The following information about the Joint Video Team (JVT) and its work may be helpful to some of you. [version: 2005-07-19]
The primary work of the JVT currently consists of:
1) scalable video coding (SVC) extension development, and
2) maintenance of the existing Advanced Video Coding (AVC) standard ITU-T Rec. H.264 & ISO/IEC 14496-10, e.g., including errata reporting and maintenance of reference sotware and conformance specifications.
The JVT currently has 3 active email reflectors.
You can subscribe to two of them (the general JVT reflector and the conformance/interop bitstream exchange activity reflector) through
http://mailman.rwth-aachen.de/mailman/listinfo/jvt-experts and
http://mailman.rwth-aachen.de/mailman/listinfo/jvt-bitstream
Alternatively, you can send email with subject or body 'help' to
[email protected].
You can reach the person managing the list at
[email protected] or
[email protected].
To subscribe to the 3rd JVT reflector (which is devoted to SVC work), send email to
"
[email protected]" containing "subscribe svc" in the body of the message.
JVT documents can be found at
http://ftp3.itu.int/av-arch/jvt-site
No password is required for access to nearly all documents on that site. A select few documents (such as integrated-format standard drafts) require password access, using a password given only to formal JVT members.
That document archive can alternatively be accessed by ftp using the same top-level site address (ftp3.itu.int) with the user ID "avguest" and the password "Avguest". This accesses the file system at the same level as the http access point
http://ftp3.itu.int/av-arch, so the directory "jvt-site" there contains the JVT document archive (the other directories there are are for various ITU-T groups -- note that "video-site" there is for ITU-T VCEG, not the JVT). That user ID and password can be considered PUBLIC information.
The JVT reference software coordination site for non-SVC work is:
http://iphome.hhi.de/suehring/tml/
No password is required for access to that site.
That software site does not have ftp access capability.
The JVT reference software access information for SVC work is:
Document JVT-O203 contains the JSVM 2 software. [Busan output, should be available *very* soon if not there yet]
Document JVT-N024 contains the JSVM 1 software. [Hong Kong output]
Document JVT-N022 contains the JSVM 0 software. [Hong Kong basis]
A CVS server for the JSVM software has been set up at RWTH Aachen, hosted at garcon.ient.rwth-aachen.de. It can be accessed using WinCVS or any other CVS client using the "pserver" method, with the user ID "jvtuser" and the password "jvt.Amd.2". The path is "/cvs/jvt", and the module name is "jsvm". For example, with a command line client, you can check out the software using the following commands.
"cvs -d :pserver:
[email protected]:/cvs/jvt login"
and
"cvs -d :pserver:
[email protected]:/cvs/jvt co jsvm"
(you can use "co" or "checkout")
The server is configured to allow read access using the above-described jvtuser user ID.
Write access to the SVC software server is restricted to JVT software coordinators Justin Ridge, Heiko Schwarz, and Mathias Wien.
Some key current documents of the JVT include:
JVT-O201/N7086 Working Draft 2 of Scalable Video Coding [05/05/20]
JVT-O202/N7084 Joint Scalable Video Model (JSVM) 2 [05/05/20]
JVT-O203/N7085 JSVM 2 Software [05/05/20]
JVT-O204/N7083 Text of Corr. to ITU-T Rec. H.264 | ISO/IEC 14496-10 AVC [05/05/13]
JVT-O205/N7081 Updated Text of ITU-T Rec. H.264 | ISO/IEC 14496-10 AVC [05/05/20]
The next JVT meeting will be in Poznan Poland. The dates that were preliminarily announced for that meeting were 23-29 July. However, we have decided to postpone the start of the meeting until the 24th. It will end around noon on the 29th. Document registrations and uploads should be completed already. If your document has not yet been uploaded, please provide it as soon as possible.
For information about logistics for the upcoming JVT and MPEG meetings in Poznan Poland (meeting location, logistics, hotels, etc.), see
http://mpeg73.multimedia.edu.pl/.
After the Poznan meeting, the plan for the next two JVT meetings will be to co-locate them with each MPEG meeting (i.e., 16-21 October in Nice France and 15-20 January in Bangkok Thailand). That co-location of meetings is expected to continue until the 1st 2006 meeting of ITU-T SG 16, upon which we plan to meet alongside SG16, approximately 12-17 March 2006. We are then likely to return to meeting with MPEG (16-21 July in Klagenfurt Austria and 22-27 October in Hangzhou China).
The JVT has two parent bodies, which are MPEG (ISO/IEC JTC 1/SC 29/WG 11) and VCEG (ITU-T SG 16 Q.6). Participation in the JVT is open to anyone who is qualfied to participate either in MPEG or VCEG, and to those personally invited by the chairmen. We are liberal in granting invitation requests.
To progress the work of the JVT between meetings, the JVT has created the following ad-hoc groups, and has appointed the following listed chairpersons for that work. The discussions involved in the work of those ad-hoc groups will be conducted on the above-listed email reflectors.
1. JVT Project Management and Errata Reporting (Gary Sullivan, Jens Rainer Ohm, Ajay Luthra, and Thomas Wiegand)
2. JM Description and Reference Software (Thomas Wiegand, Karsten Sühring, Alexis Tourapis, and Keng Pang Lim)
3. Bitstream Exchange and Conformance (Teruhiko Suzuki and Lowell Winger)
4. SVC Core Experiments (Justin Ridge, Ulrich Benzler)
5. JSVM software improvement and new functionality integration (Greg Cook)
6. JSVM Text and WD Text Editing (Julien Reichel, Heiko Schwarz, Mathias Wien)
7. Spatial Scalability Resampling Filters (Gary Sullivan)
8. Test conditions and applications for error resilience (Ye Kui Wang)
9. Test conditions for coding efficiency work and JSVM performance evaluation (Mathias Wien, Heiko Schwarz)
10. Study of 4:4:4 video coding functionality (Teruhiko Suzuki)
In the work on scalable video coding (SVC), the JVT is conducting the following core experiments (CEs). A document describing each of these CEs is available on the JVT ftp site in the 2005_04_Busan directory as document number JVT-O3xx, where "xx" is the number of the core experiment as listed below. The appointed core experiment coordinator, some participating companies, and some relevant documents (prefix the numbers below by "JVT-O" for the complete document number) are also listed below.
