- is now the default rendering technique on 8-bit color displays. You can
- revert to the ordered dithering technique (similar to that used in nv) by
- specifiying the "od" color model with the Vic.colorModel
- resource or the -c command option. Error-diffusion runs somewhat slower
- than the ordered-dither but the quality is higher. Also added support for
- computing statistically optimized colormaps using Heckbert's median cut algorithm.
- You can invoke the colormap optimization from the "Colors" panel
- in the control menu. This causes vic to compute a color histogram across
- all unmuted video streams. The histogram is then passed to a separate

- (based on the code in nv and the RTP/CellB Internet Draft). Sped up the

- conditionals in the Y/Y VQ computation. Changed the U/V VQ to use straight
- subsampling instead of LPF/subsampling since the chroma planes usually
- have little high frequency energy (and visual comparisons show negligible
- gain). Sped up decoder by replacing conditionals with straight-line code.
- But the biggest improvement was to run the conditional replenishment
- algorithm in the pixel domain instead of the cell domain. There is little
- hope of doing good temporal compression on quantized values, because the
- quantization noise is approximately a random process with variance
- proportional to the quantizer step size, and this additive noise will
- completely defeat the conditional replenishment algorithm. Running the

+<H1>vic: Change History</H1>
+<H3>v2.8ucl-1.2.1</H3><UL>
+<li> Critical Windows fix for DirectX grabber - it was crashing on startup when no devices present.
+</ul>
+
+<H3>v2.8ucl-1.2.0</H3><UL>
+<li> New codec h261as - contributed by Rhys Hawkins (Rhys.Hawkins at anu.edu.au) at Adelaide National University (ANU). This codec enables interoperability with Rhys’ VP tool available to the AccessGrid community. Use “configure –disable-h261as” to disable it. Built also for Windows.
+<li>Removed win32/vergen.bat from repository as it is auto-generated.
+<li>Added NSIS installer script to auto-generate installer (requires NSIS installed on Windows, http://nsis.sourceforge.net).
+<li>Added image overlay support. This allows a PPM image to be used as an institutional logo, (for example, added sample UCL logo file: ucl_logo.ppm), which can be placed and moved over the video window. Overlays work with all grabbers and codecs. The logo image can also be specified as a vic resource (in .vic.tcl) so that it is made available at startup. Also, tweaked error return values from oTcl to C++, so that all errors relating to overlays are handled gracefully.
+<li>Added STATIC_BUILD to preprocessor to get rid of nuisance MS Linker warnings (tcl/tk libraries are statically built and linked).
+<li>Got rid of 422 format in the Windows DirectX/WDM grabber. 422 was crashing vic as it doesn’t return any grabber (not implemented). Maybe we should write one.
+<li>Added a LICENSE file.
+<li>Added “focus” property in the generic tcl mk.entry() function that builds text entry widgets.
+<li>Fixed isset call to is_set() - isset is defined elsewhere in Linux
+<li>Added more graceful error handling so Vic will bring up a warning dialogue instead of crashing.
+<li>Added Source-Specific Multicast (SSM) support - tested IPv4 on WinXP. IPv6 on Linux not fully tested.
+<li>Adapted confbus Tcl/Tk application startup code to using WIN32 socket API (net/cbAppInit.c).
+<li>Fixed various compiler warnings (VS7.1).
+<li>FreeBSD patch to use system-wide functions MD5_xxx(). (Continue use MD5xxx() functions on Windows/Linux).
+<li>Changes contributed by Colin Perkins to account for MacOS X. Vic now builds on MacOS X 10.4.6.
+<li>Commited a number of fixes mainly by peeking into Debian, FreeBSD, and Gentoo ports. These fixes are described in detail on the wiki: https://frostie.cs.ucl.ac.uk/nets/mmedia/milestone/sumover-1Qb-release and related tickets: 37, 41, 42, 43, 44, 45, 46. Summary of main fixes:
+<UL>
+ <li>fixed rat man page problem for Debian
+ <li>using intptr_t casts for 64-bit architectures in vic
+ <li>added missing #includes, and removed redundant ones
+ <li>added some missing function prototypes
+ <li>better fix for GETTIMEOFDAY_TO_NTP_OFFSET
+ <li>using delete[] for some objects allocated with "new"
+ <li>using various casts, including (sig_t) for unix signals
+ <li>now using intmax_t cast for time_t struct
+ <li>use srandomdev() instead for srandom() in FreeBSD
+ <li>use openssl's md5 instead of vic's own, link to -lcrypto
+</UL>
+</UL>
+<H3>v2.8ucl-1.1.7</H3><UL>
+<LI>New Windows DirectX/WDM Grabber - contributed by Mark Petrovic (mspetrovic at gmail.com) whilst at Earthlink.net
+<LI>Updated video4linux2 driver so it works with latest API - i.e. with linux kernel 2.6.x. Modified configure to so it can be selected. The old v4l2 driver is still there as grabber-v4l2-old.
+<LI>Updated configure so it includes both v4l1 v4l2 drivers as there are still devices that use v4l1 in 2.6.x kernel - like the Philips USB cams.
+<LI>Updated v4l1 to cope with some more v4l1 devices (Philips USB) - based
+on MASH <a href="http://www.openmash.org/lxr/source/video/video-v4l.cc">v4l</a>
+<LI>Modified grabbers to set status_= -1 for graceful tcl error handling (instead of curret exit() or abort()).
+<LI>Added Visual Studio Project files (*.vcproj)
+<LI>Modified xv-grabber so it's optional in configure. Also modified it to handle mulitple devices - though none to test with. </ul>
+<H3>v2.8ucl-1.1.6</H3><UL>
+<LI>Modified Windows grabber so 'configure on Transmit' is required for any video grabber config dialogues to appear.
+<LI>Fixed tcl to handle hostnames properly
+</UL>
+<H3>v2.8ucl-1.1.5</H3><UL>
+<LI>Added generic case to vfw grabber that doesn't abort.
+<LI>Added support for Intel Smart Video Recorderer to vfw grabber.
+<LI>Fixed code in cf-network.tcl to handle ttl's greater than 16 and to do IPv6
+properly with layered streams.
+<LI>Added fix from Chris Greenhalgh <cmg at cs.nott.ac.uk> to syncronise the vfw
+callback thread with vic - stops frames being grabber before vic has finished
+processing them.
+</UL>
+<H3>v2.8ucl-1.1.4</H3><UL>
+<LI>Added check in configure to turn off optimisation in h261 decoder code if we're using GCC 2.96 (otherwise it crashes).
+<LI>Spec file for Linux RPMs
+<LI>Added loopback fixes
+<LI>Added win2k debug and release builds.
+<LI>Increase size of ipv6_mreq struct by 4 bytes on win2k because of bug in MS v6 library
+</UL>
+<H3>v2.8ucl-1.1.3</H3><UL>
+<LI>Updated so a new menu item is added to each decode window allowing users to select number of layers to receive on a layered feed. The Encode layers slider used to attempt do this but didn't work with more than one layered feed.
+<LI>Added number of layers indicator to info field on decoded feeds
+<li>Added windows dialog for display of usage info.
+<LI>Tweaked decoder control so it changes when ecnoding changes
+<LI>Added -v option to ouput version number.
+<LI>Added command line options to specify interface (-i addr) and IPv6 interface index (-x index)
+<LI>Updated to use getaddrinfo for name lookup - using the supplementary function included into common library when using MUSICA IPv6.
+<LI>Re-enabled the fprintf to print warnings u as dialogue boxes under Windows.
+<LI>Altered the way the addresses are allocated - Now referenced through the network object (Before they were allocated by stepping thru all available address types untill one address type resolved - Which could have caused some problems - also generated errors from the failed resolve attempts)
+<LI>Tweaked IPv6 address allocation functions to compile on gcc-2.9
+<LI>Corrected the positioning of the padding bit in the rtcp header. Retained some compatibility with old version which used to put it in first packet. Also the length in the rtcp packet did not include the padding - it now does. It doesn't appear to break when interworking with the older version so far....
+<LI>Corrected bug which meant vic attempte to delete it's local src from the list of sources when it appears to go idle for a long time - happens when vic gets suspended for a while.
+<LI>Altered net-ipv6 so the IPv6 interface index is not used IPV6_MULTICAST_IF unless set on the command line as it seems to cause problems for FreeBSD. It is now set to -1 in the resourses to indicate its uninitialised state.
+<LI>Tweaked config.h to include some defines needed by FreeBSD 2.2.8
+<LI>corrected IPPROTO_IP used in net-ipv6 loopback command to use IPPROTO_IPV6
+<LI>Tweaked so the send socket binds to command line specified -i interface, if specified, otherwise it binds to in6addr_any
+<LI>Corrected bug in IPv6 when TTL is set on Command line - it was calling the ipv4 proc to check for multicast - now calls in6_multicast
+<LI>Enabled -m (mtu) option on command line - Use with care as not all codecs will behave correctly. (it's default is 1024).

+<H3>v2.8ucl-1.1.2</H3><UL>
+<LI>Fixed RTCP bug - The SSRC wasn't being set when transmitting (well it was always -1)

+<LI>Reorganised code into directory structure reflecting the functionality of
+the different modules of vic - in a style not disimilar to
+<a href="http://mash.cs.berkeley.edu/mash/index.html">MASH</a>.
+<LI>Moved vic over to use <b>UCL's version's of tcl/tk</b> - this is due to a
+number of problems we have encountered here;
+The variety of versions of tcl/tk installed on target machines can be very
+wide and therefore provides us with a multitude of bugs and 'problems' that are
+not related to our code. We now ship the code now with UCL statically linkable
+version of tcl/tk (which also uses compiled in versions of the 'init' scripts
+as opposed to system installed which also lead to trouble) to minimise such
+problems. It is still possible to get vic to use the standard libraries by
+specifying -without-ucltk, and/or -without-ucltcl (though we cannot offer
+much help with problems created by different tcl/tk versions).
+<LI>Moved vic over to use <b>UCL's common library</b> so it shares the codebase
+provided by rat - where possible; It now uses common DES code and Mbus code -
+so both the DES and Mbus sections have been re-written.
+<LI>The meteor grabber has been fixed (using the source from the freeBSD version) for FreeBSD and vic now compiles under FreeBSD.
+<LI>A number of useful fixes for the video4linux grabber plus new control panel
+from <a href="mailto:jmo at medialab.chalmers.se">Jean-Marc Orliaguet</a>
+<LI><b>IPv6 support under UNIX and WIN32</b>. Under UNIX this enabled by specifiying
+the --enable-ipv6 directive to configure. We have tested it with
+Solaris 7 ipv6, Linux 2.2.5 ipv6 kernel support.
+<LI>Created an MS Visual C++ 6.0 project for compilation of vic under win32
+environments - this also, unfortunately, meant we had to rename all C++ files
+from .cc to .cpp. The project has a number of different configuration choices;
+Debug, Release, Debug_IPv6 (Microsoft research's IPv6 - requiring NT 4.0,
+<a href="http://www.research.microsoft.com/msripv6">MS ipv6</a> version 1.3 and
+MS DDK), Debug_IPv6-Musica (a non-free ipv6 implementation from Thompson-CSF).
+<LI>Now IPv6 host addresses and multicast addresses are automatically
+recognised and vic will attempt to use IPv6 (if compiled in).
+</UL><H3>v2.8ucl5</H3><UL>
+<LI>Fixed -l option so it instead generates a filename automatically of the form: "vic-{timestamp -seconds}-{local IP addr}-{username}". It now works under Windows and UNIX. (Under Windows the tcl command 'puts' had been redefined so that it did not write to a file at all (only to stdout/stderr) - I added the necessary code). The output is of the form:<br>
+Cname timestamp framerate bps loss

+<LI>Added support transmitting a static JPEG image from a file. Contributed by <A HREF="mailto:olson at mcs.anl.gov">Bob Olson</A>. You need to set <I>Vic.stillGrabber</I> to <I>true</I> in order to get a <I>still</I> device in the Device menu-button. When you select this device, a panel will be inserted in the control menu to let you specify the file anme for an RTP/JPEG type-0 frame. This crude interface is currently just for testing. </LI>
+<LI>Fixed compilation problems with SGI's C++ compiler. Reported by <A HREF="mailto:arc at sgi.com">Andrew Cherenson</A>. </LI>
+<LI>Kevin Fall added support for ``fast Intra-H.261'' encoding using JPEG hardware. The idea is to use a JPEG board as a DCT engine by Huffman decoding each JPEG MCU. We then carry out conditional replenishment in the DCT domain and hand the frame buffer of DCTs to a modified H.261 encoder. The trick is to convert 4:2:2 color decimated JPEG into 4:1:1. This technology is described in our <A HREF="http://www.cs.berkeley.edu/~elan/articles/pub/vgw.ps">ACM Multimedia paper</A>. (By default, this is currently disabled. Enable it by setting <I>Vic.useJPEGforH261</I> to true.) </LI>

We now use an md5 hash and the algorithm/key syntax suggested by <A HREF="mailto:M.Handley at cs.ucl.ac.uk">Mark Handley</A>. For example, DES1/secret-key implies the standard DES algorithm with cipher-block chaining with key "secret-key" while DES3/secret-key implies triple DES. Added "DULL" encryption module for test purposes and as an example for integrating modules. </LI>
+<LI>Fixed md5 header file (global.h) to set 32-bit typedef appropriately for alpha; otherwise, it doesn't work correctly (and encryption keys are synthesized incorrectly). </LI>
+<LI>[internal] Merged the Transmitter and SessionManager objects since packet transmission depends on the session type. </LI>

+<LI>Added check for *rtpName and *rtpEmail resources at start-up. If they don't exist, a dialog box queries the user and stores the new values in ~/.RTPdefaults. This seems like a more robust (albeit annoying) approach compared to the heuristics of used to find a fully qualified domain name. </LI>

+<LI>Added a frame grabber for the SlicVideo SBus adaptor. Contributed by <A HREF="mailto:Toerless.Eckert at Informatik.Uni-Erlangen.de">Toerless Eckert</A>. </LI>
+<LI>Added a new mechanism to present grabber specific controls in the main menu. If a grabber wants such controls, the corresponding tcl procedure build.grabberName should exist (and build the UI). grabberName is the device "nickname", e.g., build.slicvideo exists to build the SlicVideo controls. When the user switches devices, the corresponding control panel is automatically removed and inserted by tcl support code. This extension suggested by <A HREF="mailto:Toerless.Eckert at Informatik.Uni-Erlangen.de">Toerless Eckert</A>, <A HREF="mailto:allas at Apple.COM">Joe Pallas</A>, and others. </LI>
+<LI>[internal] Changed SessionManager::chkdup() to match sources who never sent data so that sites that exit abnormally don't build up source table. </LI>
+<LI>Fixed some bugs in the conditional replenishment algorithm and changed implementation to make it more intuitive. Encoders no longer alter the contents of the cr vector. Also, extended the old model from two types of blocks to three (motion, aged, and background), with three levels of quality. </LI>
+<LI>Enhanced H.261 encoder to do adaptive quantization. High motion areas are sent at low-quality (for higher update rate), ``aged'' blocks are sent at medium-quality, and background blocks are sent slowly at very high quality. </LI></UL>

Reported by <A HREF="mailto:Craig.M.Votava at att.com">Craig Votava</A> and <A HREF="mailto:hoofar at sgi.com">Hoofar Razavi</A>.

+<LI>[internal] Added tcl hook so that decoder can assert that stream parameters have changed in a way that might affect the rendering modules. For example, the RTP/JPEG type might change causing the output format to change from YUV-422 to YUV-411. In this case, we might have disable hardware decoding (because the hardware doesn't support 411) or reallocate the software renderers because they depend on the decimation factor. </LI>

+<UL>
+</I><LI>Added support for the Parallax jpeg adaptor (both JPEG and standard capture are supported). Contributed independently by Joe Pallas (Pallas at Apple.COM) and Sai Rathnam (rathnam at cse.ogi.edu). </LI>
+<LI>Added a "Message" form to the control window so that user's can leave a descriptive message on the state of the transmission (for example, "out of office" or "meeting resumes at 2pm"). When the message is present in a stream, the corresponding "info" button is highlighted, which invokes the info window containing the text. (These messages use RTPv2 TXT SDES items.) </LI>
+<LI>Added Vic.sunvideoDevice X resource to indicate an alternative device to use. Set it to a small integer n to tell vic to use device /dev/rtvc{n} and /dev/rtvcctl{n}. This change suggested by Hanan Herzog. </LI>
+<LI>Added support for sending decoded video to an external (analog) output port under SGI VL (for example, SGI's galileo board has a composite output jack). </LI>
+<LI>Changed the default format to H.261. </LI>
+<LI>Added encryption hooks. You need to obtain a DES library elsewhere in order to build a vic with encryption support. </LI>
+<LI>Improved statistics displays with a legend and the ability to plot (via a stripchart) multiple statistics simulataneously. A stripchart is created in a separate window by clicking on the name of the desired statistic. Added an "info" window without the clutter of all the stats. </LI>
+<LI>Added a "Decoder panel" to the control menu with several controls for manipulating vic's decode-side functionality. You can now interactively select the dithering algorithm on an 8-bit display to dynamically change the number of colors used by vic. For example, if you want to run a color-intensive application but leave vic up, you can select the "Gray" dithering option, run your application and when done, revert vic back to color dithering. You can also adjust the gamma factor. If you set the gamma factor to 1.0 and select and "ordered dither", vic will use the standard 5x5x5 color cube. Since other applications use this same cube (e.g., wb, gs, and nv), you are less likely to run out of colors because of colormap conflicts. These controls are disabled when your running on an 24-bit or mono display. With these changes, you no longer specify the dithering algorithm using Vic.colorModel. Instead, you specify a visual with Vic.visual (i.e., truecolor, pseudocolor, etc) or with -V or -Xvisual (e.g., -Xvisual=truecolor). For 8-bit pseudcolor visuals, the default dithering algorithm is specified with Vic.dither (or -c, or -Xdither), but can be overridden in the user-interface (as explained above). The visual cannot be changed after startup. </LI>
+<LI>Added a "Save-CPU" toggle-button under the viewing-window "Modes" pulldown menu, which reduces the update rate of the window. This allows you to open a local looped back window for monitoring the outbound transmission without incurring the cost of rendering every frame in real-time. </LI>
+<LI>Changed "for" statement conventions to adhere to the proposed ANSI standard change which re-defines the lexical scope semantics of the initializer statement as described in http://www.cygnus.com/~mrs/wp-draft/stmt.html#stmt.for In order to be compatible with both the old and new semantics, we have changed all instances of for (int i = ... ) ... use(i); to int i; for (i = ... ) ... use(i); </LI>
+<LI>Ported to tk-4.0. You'll need BLT-1.8 to build vic from source. An unofficial BLT-1.8 is available from http://www.cs.uoregon.edu/jhobbs/. </LI>
+<LI>Merged changes from Michael Speer (speer at eng.sun.com) to compile with Sun's C++ compiler. </LI>
+<LI>Deleted -r option (for RTIP) and added more generic -n option to specify the communications protocol underneath RTP. "ip" (for IP or IP Multicast), "rtip" (for Tenet RTIP), and "atm" (for the Fore SPANS ATM API) are supported. </LI>
+<LI>Added Vic.defaultDevice X resource to specify initial selection of device when multiple devices are present. </LI>
+<LI>[internal] Migrated voice-activated switcher code from C++ to tcl. </LI>
+<LI>Added code to randomize the RTP initial sequence number and media timestamps to foil plaintext attacks in case encryption is used (as specified in the RTP spec). Choose a heuristic random seed using an MD5 hash as suggested in the spec. </LI>
+<LI>Eliminated support of unidirectional RTIP connections (i.e., connections are now always esatblished in both directions). </LI>
+<LI>Changed VL module to query available devices and list each device separately in the control panel. Also, added code to query the available input ports and dynamically configure the port menu accordingly. </LI>
+<LI>Changed RTP presentation timestamps to the 90Khz format agreed upon at the July 1995 Stockholm IETF. </LI>
+<LI>[internal] Fixed bug where a garbage video stream (e.g., from an encryped session) could cause rendering code to fault. Problem is that rendering code assumes (possibly scaled) output image width is an integral multiple of four (which is true for the range of supported scales and the geometries of standard video streams). Since this is a pathological condition, the fix is to simply disable rendering of such streams thereby avoiding the software fault. In theory, non-standard video sources (like X screen captures) could fall into this category and hence appear as a "gray window". This problem reported by Ian Wakeman (I.Wakeman at cs.ucl.ac.uk). </LI>
+<LI>Added support for point-to-point ATM transport via Fore's API, thanks to Anastasio Andrea Scalisi (scalisi at mailer.cefriel.it). In the process of integrating this code, reworked network object support so that new network abstractions can be more easily added. Added -n flag to specify network type. For example, "-n ip", "-n atm", and "-n rtip" are currently supported (ip is the default). </LI>
+<LI>Added hack to be able to utilize two DEC JPEG boards simultaneously. The environment variable JVIN_PORT specifies the jvdriver port number to connect to for the capture board. The decode side uses the default port. This change contributed by Lance Berc (berc at pa.dec.com). </LI>
+<LI>Deal gracefully with shared memory allocation failures. Added code to print out an error message and revert to non-shared buffers. </LI>
+<LI>Fixed bug in voice-switched windows where a speaker without a video stream would cause the window to be switched to the first thumbnail. </LI>
+<LI>Added validity check for new packet stream. Only accept a new source when we've seen two in-sequence packets; suggested by Ian Wakeman (I.Wakeman at cs.ucl.ac.uk). This check prevents vic from allocating an unbounded number of demultiplexing data structures when confronted by a stream of garbage (e.g., such garbage results when listening to an encrypted session without the key). </LI>
+<LI>Changed reception reports loss semantics to conform to 3/21/95 RTP draft (draft-ietf-avt-rtp-07.txt) (in particular, the extended highest seqno received field, the loss fraction, and the cumulative loss fields of the reception report were updated). </LI>
+<LI>Added check for duplicate packets in common receive path so that they are now reported in the stats window for all compression formats. </LI>
+<LI>Added support for SGI Cosmo JPEG board. Because this board was designed for non-linear video editing, it has large latencies that preclude good interactive operation. </LI>
+<LI>[internal] Moved code to allocate framer buffers etc., which is shared among all the grabber subclasses, into the grabber base class. Changed the way grabbers specify their attributes; they simply return a nested tcl list. Reorganized all tcl-style objects (i.e., widgets that implement tcl commands) so that they derive from a shared TclObject base class. Support hardware assisted decoding via new Assistor class (instead of having separate Decoder objects). Assistors are analogous to Renderers; the latter support software decoding. Revert to model where there is only one Decoder object per incoming stream. </LI>
+<LI>[internal] Reworked the way encoders and grabbers are allocated to make it easier to add support for the encode-side of a new format. Suggested by Joe Pallas (Pallas at Apple.COM) </LI>
+<LI>Fixed bug that caused crash using DEC j300 hardware JPEG decoder. Problem was that default Vic.jvColors was not defined. Reported by Stefan Savage (savage at cs.washington.edu). </LI>
+<LI>Changed video capture modules to embed NTSC sized images into CIF sized frames with a gray border instead of using ugly scaling. PAL is still handled the same way (i.e., 16 pixels from each line are discarded). </LI>
+<LI>Changed default position on frame rate slider from two to eight. </LI>
+<LI>Added support for native size 4:1:1 YUV grabbers (i.e., not just CIF dimensions). </LI>
+<LI>Added support for the VigraPix frame grabber. Thanks to Steve Haehnichen (steve at vigra.com) and Vigra for the donation of a board. </LI>
+<LI>[internal] Changed CR to operate on 16x16 instead of 8x8 blocks. </LI>
+<LI>Changed perceptually weighted H.261 quantization. Previous scheme that folded the weighting in with the DCT quantization was deficient because in addition to increasing the dead zone, it threw away bits unecessarily (and the loss of these bits was not captured by the h.261 entropy coder). Instead, we now increase the dead zone using perceptual weighting after we do quantization. </LI>
+<LI>Fixed bug in conditional replenishment algorithm. CR decision was based solely on the first 8 pixels of every block, so motion of small items (like pointers) left artifacts behind. Fix was to advanced CR scanline pointer (as intended in the algorithm). </LI>
+<LI>Updated H.261 framing to conform to July 1995 Internet Draft "RTP payload format for H.261 video streams" (draft-ietf-avt-h261-01.txt). Maintained backward compatibility with ivs encoder by using the RTP version number to imply the old encapsulation format. Once ivs switches to RTPv2, we can abandon the GOB reassembly code. </LI>
+<LI>Patched memory leak in nv encoder. Thanks to Bernd Lamparter (lampart at ICSI.Berkeley.EDU) and Wieland Holfelder (whd at ICSI.Berkeley.EDU). </LI>
+<LI>Fixed bug where checkXshm was not detaching the test shared-segment in the X server. The X server could see two XShmAttach's with the same shmid (one readonly the other read/write), and the prior one becomes invalid. Bug fix from Srinivasan Seshan (ss at cs.berkeley.edu). </LI>
+<LI>Added check for session packets arriving on data port. This should eliminate the gray windows with fmt-0x1 and fmt-0x0 as the media type. </LI>
+<LI>Fixed bug where source sequence number was reset to 0 when changing the compression format. This would cause receivers to reset their packet counts, which in turn, caused inconsistent reception reports. Problem reported by Paul Stewart (stewart at hibp6.ecse.rpi.edu). </LI>
+<LI>Shared memory with the X server now works under BSD/OS 2.0. Unfortunately, the BSD/OS 2.0 X server is not compiled with the XShm extension. You might ask Srinivasan Seshan (ss at cs.berkeley.edu) for a pre-compiled XFree86 server, if you don't feel like building one from scratch. </LI>
+<LI>Fixed session message timestamps to conform to NTP epoch instead of unix 1970 epoch. Bug reported by Bernd Deffner (deffner at fokus.gmd.de). </LI>
+<LI>[internal] Fixed bug where rtpv2 source tcl-methods were derived from the RTP SSRC. This caused numerous problems when sources would come and go (or when SSRC's collided, which is relatively common with the heuristic to generate them in rtpv1 compat mode). </LI>
+<LI>Changed semantics of -u. File argument to -u is sourced after the built-in tcl script. Previously, -u completely overrided built-in script. </LI>
+<LI>Added code to source $HOME/.vic.tcl if it exists. This file is sourced after the built-in tcl script, but before the file argument to -i. Suggestion from Bill Fenner (fenner at parc.xerox.com). </LI>
+<LI>[internal] adaptive load rendering </LI>

+<LI>[internal] Made it easier to add new decoders. A new format can be supported without having to change any existing code. Design change suggested by Joe Pallas (Pallas at Apple.COM). </LI>
+<LI>[internal] Established convention that all YUV image buffers are contiguous so that chroma offsets can be computed where needed (and only a single pointer need be maintained). </LI>
+<LI>[internal] Reimplemented switcher architecture in tcl and created generic Conference Bus object. </LI>
+<LI>Changed semantics of -u option so that file argument is sourced in addition to (rather than in place of) the built in tcl code. </LI>
+<LI>Incorporated Garrett Wollman's (wollman at lcs.mit.edu) patches for FreeBSD. </LI>
+<LI>Fixed some problems with the VL grabber. Added PAL CIF support and code to choose from set of allowable frame rates (frame rate problem reported by many - thanks). Deleted vlSelectEvents call. Fixes from Andrew Cherenson (arc at sgi.com). </LI>
+<LI>Converted configuration scheme to use GNU autoconf. If you encounter problems running ./configure, please see if you can fix things by modifying configure.in and running autoconf (avaialable in ftp://prep.ai.mit.edu/pub/gnu/autoconf*). Then, send us your fixes so vic's configure script will work out of the box for you in the future. </LI>
+<LI>Changed binding on pull-down menu buttons so that you can click on button a second time to make the menu go away. This change suggested by Pat Parseghian (pep at research.att.com). </LI>
+<LI>Fixed xil grabber to conform to Solaris-2.4 API. Problem reported by David Meyer (meyer at network-services.uoregon.edu) and Michael Mealling (Michael.Mealling at oit.gatech.edu). </LI>
+<LI>Changed Vic.defaultRate to Vic.framerate to make less ambiguous, and fixed explanation in man page, which was bogus. Reported by Pat Parseghian (pep at research.att.com). </LI>
+<LI>Fixed bug with default format (it was never used). Reported by Pat Parseghian (pep at research.att.com). </LI>
+<LI>Fixed bug where color button would get out of sync with actual color disposition when changing encoding formats. Reported by Pat Parseghian (pep at research.att.com). </LI>

+<LI>Changed VIC.SD.TCL script to use ivs (instead of vic in ivs compat mode) by default, since ivs' rate control scheme depends on feedback reports that vic does not generate. </LI>
+<LI>Made H.261 decoder more robust to packet loss and reordering. Problem reported by terje.vernly at usit.uio.no. </LI>
+<LI>Upgrade release status from ALPHA to BETA. </LI>
+<LI>Incorporated John Brezak's (brezak at apollo.hp.com) changes to support generic Xvideo devices. He says: </LI>

+<UL>
+<LI>You need a fixed libXv.a (get the source from ftp.x.org and apply patch in grabber-xv.cc) </LI>
+<LI>Haven't implemented cif_grabber(). Maybe next week. </LI>
+<LI>There are 2 config options - XV_PSEUDO8 and XV_USES_XSHM . XV_PSEUDO8 is for allowing an 8bit visual to be used to upply a capture window for a 24bit image. HP does this. XV_USES_XSHM is for an Xv extension that can use the SHM versions of image operations. Parallax currently doesn't support this on HP. </LI></UL>

+<H3>v2.4alpha (no v2.3) <I>Tue Nov 29 04:53:15 PST 1994</H3>
+<P>(First public release)</I> </P>
+
+<UL>
+<LI>Added -P command line argument to force use of private colormap. </LI>
+<LI>Added the -X command line argument. "-X resource=value" will override an arbitrary vic resource on the command-line. Removed -e and -p options. </LI>
+<LI>[internal] Reworked packet demultiplexing code so that it is independent of vic, eventually allowing it to be shared by other applications (i.e., vat, wb, etc). The motivation is to share as much code as possible with vb. </LI>
+<LI>Fixed usage message. </LI>
+<LI>Added support for -o, which dumps locally sourced video to an RTP clip file. </LI>
+<LI>Added Vic.filterGain resource for controlling time constant on bit-rate, frame-rate, and loss estimators. Default is 0.25. </LI>
+<LI>Changed menu popup to have generic layout indepedent of capture device. Portions of the interface are enabled or disabled by querying the device to see what features are supported. </LI>
+<LI>Fixed H.261 encoder to do GOB-oriented rather than frame-oriented fragmentation. </LI>
+<LI>[internal] Added traffic smoothing so packets are evenly spaced across a frame time. This adds latency but is necessary given the current constraints of Internet routers. </LI>
+<LI>[internal] Do second cut on rtp/jpeg reassembly code. This version does a reasonable job with misordered packets etc. </LI>
+<LI>[internal] Reorganized grabber/encoder architecture so that conditional replenishment algorithm is carried out by the grabber. This saves bus bandwidth because blocks that are to be suppressed need not be copied from the grabber specific format to the format expected by vic. If the capture device uses programmed I/O, there is little advantage but no disadvantage. You might think this would complicate the grabbers, but most of the work is carried out by a generic macro. </LI>
+<LI>[internal] Converted bstrings routines to posix equivalents. </LI>
+<LI>Changed the polarity of -H, which nows means use hardware decoding if available. The default is not to use hardware assist (see the man page for an explanation). </LI>
+<LI>Added support for error-diffusion dithering, thanks to Elan Amir. Error diffusion dithering is now the default rendering technique on 8-bit color displays. You can revert to the ordered dithering technique (similar to that used in nv) by specifiying the "od" color model with the Vic.colorModel resource or the -c command option. Error-diffusion runs somewhat slower than the ordered-dither but the quality is higher. Also added support for computing statistically optimized colormaps using Heckbert's median cut algorithm. You can invoke the colormap optimization from the "Colors" panel in the control menu. This causes vic to compute a color histogram across all unmuted video streams. The histogram is then passed to a separate program (vic_colord) to carry out the median cut. We fork off a separate process because the computation is CPU intensive and will block the user-interface if not run as a separate thread. </LI>
+<LI>Changed 24-bit display code to use full 24-bit precision instead of a 16-bit lookup table (thanks to Van Jacobson). </LI>
+<LI>[internal] Reworked the way windows are sync'd to the frame buffer. </LI>
+<LI>Use private colormap when default colormap is too full. </LI>
+<LI>Compile with gcc-2.6.0 under DEC OSF. DEC's C++ compiler is no longer supported. </LI>
+<LI>[internal] Changed ppmtolut and color-lut.cc to use convention that grays are explicit in the stored color map. </LI>
+<LI>Added support for simple INTRA-only H.261 encoding. </LI>
+<LI>[internal] Major changes to DCT code and software decoders for substantial speedups. Employ Arai, Agui, and Nakajmia's 8pt 1D DCT, from Fig. 4-8 Pennebaker & Mitchell (i.e., the pink JPEG book). By computing scaled DCTs on each of the column and row passes and folding the descaling step with quantization step, only five multiplies per 8-pt DCT are required, resulting in a 90-multiply 8x8 DCT. Thanks to Martin Vetterli for explaining how to do this. </LI>
+<LI>Fixed bug that caused core dump if there is no USER enviroment variable defined (and Vic.sessionName is not defined). Some shells don't define USER (i.e., ksh under solaris). </LI>
+<LI>[internal] Reworked speedups in software jpeg decoder. Instead of caching mappings between huffman strings and decoded blocks (which required an infeasibly huge hash table for good quality video), we reduce load by skipping over any block that is sufficiently similar to the same block that's currently displayed. The similarity comparison can be carried out cheaply in the quantized, DCT domain. </LI>
+<LI>Change thumbnail frame rate to report decoding frame rate when not disabled and receiving frame rate when disabled. The decoding rate can be lower than the receiving rate if the local cpu can't keep up with the source, or if there are no active windows (besides the thumbnail) which means we don't have to decode every frame. </LI>
+<LI>Modified thumbnail/info window so that sites are always sorted in lexicographic order (by rtp NAME attribute). </LI>
+<LI>Modified thumbnail/info window to tile according to the number of columns specified in the "Tile..." pulldown in the Menu window. The default value is 1, and can be overridden with the the Vic.tile resource. You can also type a number into the thumbnail window as a shortcut. </LI>
+<LI>If 75dpi fonts aren't available, change all fonts to wildcard the pitch. </LI>
+<LI>Sourcing video from clip files is no longer supported. This functionality is now provided by rtp_play. </LI>
+<LI>Added source rate statistics to transmission panel in menu window. This way you can monitor how fast you're sending even if the loopback decoding can't keep up. </LI>
+<LI>Added Vic.defaultFormat resource to set the default video transmission format. If not specified the default is determined by your capture hardware (for example, jpeg is default if you have jpeg hardware ). </LI>
+<LI>Ported to Solaris 2.3. Added XIL support for raw capture and JPEG, H.261 and CellB hardware capture (the sunvideo card currently doesn't implement H.261). </LI>
+<LI>[internal] Generalized jpeg decoder to deal with arbitrary decoder parameters (and subclass special cases to optimize). In particular, we can now deal with 4:1:1 jpeg, which the SunVideo produces. </LI>
+<LI>Add code to distinguish between j300 and jvideo and for the latter to disable non-JPEG formats and 1:1 decimation. </LI>
+<LI>Added code to receive path to always deal with RTP version 1 packets properly. </LI>
+<LI>[internal] Created SoftwareDecoder, PlaneDecoder, and SoftwareRenderer sub-classes so that a bunch of common code could be shared among the decoders. </LI>
+<LI>[internal] Broke out block suppression code into separate sub-class so it can be shared among the nv, nvm, and cellb encoders. </LI>
+<LI>Small change to architecture to cope with dynamic geometry and video format changes. </LI>
+<LI>Ported to DEC OSF/1 v2.0. </LI>
+<LI>Added CellB support (based on the code in nv and the RTP/CellB Internet Draft). Sped up the encoder by a factor of two by using straight-line code instead of conditionals in the Y/Y VQ computation. Changed the U/V VQ to use straight subsampling instead of LPF/subsampling since the chroma planes usually have little high frequency energy (and visual comparisons show negligible gain). Sped up decoder by replacing conditionals with straight-line code. But the biggest improvement was to run the conditional replenishment algorithm in the pixel domain instead of the cell domain. There is little hope of doing good temporal compression on quantized values, because the quantization noise is approximately a random process with variance proportional to the quantizer step size, and this additive noise will completely defeat the conditional replenishment algorithm. Running the differencing in the pixel domain will give much more effective temporal compression, which reduces network bandwidth and saves CPU cycles. </LI>
+<LI>Fixed bug that caused nv & ivs senders to never be deleted from the main window. </LI>
+<LI>Changed model so that video capture device is opened first time transmission is invoked, as opposed to at start-up. Still need to implement device sharing as vat does with non-shareable audio hardware. </LI>
+<LI>Fragment JPEG streams instead of letting IP do the fragmentation. RTP/JPEG protocol still in limbo. </LI>
+<LI>Changed semantics for clicking on thumbnail. If the site is already being displayed (in locked mode), the corresponding window is deleted. Otherwise, it is created as before. This gives toggle-like behavior as in nv. </LI>
+<LI>Always use vanilla rtp headers instead of vic-specific packet format. </LI>
+<LI>Improvements to ordered dithering code. Incorporated Ron Frederick's model from nv v3.3alpha, i.e., to fold the dither matrix into the color-to-pixel lookup table. Van sped up this code by incorporating his hacks from the 24-bit color code. </LI>
+<LI>Improvements to user interface. Looks more like vat now. </LI>
+<LI>Added -c to specify the color rendition technique. </LI>
+<LI>Added support for 24 bit displays (thanks to Van Jacobson). </LI>
+<LI>Added support for pip/tx grabber on decstations. </LI>
+<LI>[internal] Reworked grabber/encoder architecture. Added Device class. Arranged for most action to be initiated via tcl "device" command. </LI>
+<LI>[internal] Reworked jv grabber so that SharedVideoImage class allocates the shared memory. This means won't match the mme grabber model (i.e., the mme server will do the memory allocation), but that's okay since the right way to handle this is derive an MmeVideoImage from a SharedVideoImage. </LI>
+<LI>[internal] Changed all tcl grabber hooks to use the "grabber" command. Subclasses can catch invocations via the virtual method Grabber::command(argc, argv). </LI>
+<LI>Changed -f to -u to be compatible with vat (since vat already used -f for audio format). Changed previous -u flag to -U. Changed "-e encoding" to "-f format" to be consistent with vat. v2.2alpha Tue Nov 23 15:20:59 PST 1993 </LI>
+<LI>Added support for decoding H.261 video. (The encoder isn't implemented yet.) </LI>
+<LI>Added the -A flag. '-A nv' for nv compatibiliry; '-A ivs' for ivs compatilibility. Took away '-n'. </LI>
+<LI>Fixed bug introduced in 2.1a that caused core dump on window resize. v2.1alpha Tue Nov 9 14:52:59 PST 1993 </LI>
+<LI>Fixed bug that caused sparc-10 core dumps during xunet conference. </LI>
+<LI>Default JPEG decoder to color output instead of gray scale. </LI>
+<LI>Allow control window to be vertically resized. </LI>
+<LI>Fixed conference title bug. Default addr/port version wasn't displayed. </LI>
+<LI>Fixed bug that caused 12 bytes of garbage at front of nv packets. </LI>
+<LI>Fixes to compile with gcc under DEC/OSF. </LI>
+<LI>Update to tcl7.1/tk3.4. </LI>
+<LI>First cut at man page; needs much more work. </LI>
+<LI>Eliminate chud at bottom of J-Video windows that are 232 pixels high instead of 240. </LI></UL>
