The First JCT-VC Meeting, Dresden, DE

Jie Dong — Sat, 19 Jun 2010 08:51:43 +0000

During Apr. 15-23, 2010, the first meeting of JCT-VC was held in Dresden, DE. In the meeting, 27 responses to the Call for Proposal, issued in Jan. 2010, were reviewed and the associated video material was evaluated in extensive subjective tests.

Tentative Conclusions from CfP Responses Reviews

Coding tools used in respective proposals are listed in JCTVC-A203. High-level noteworthy aspects from the review of the proposals and the outcome of the subjective tests are outlined:

Substantial progress in coding efficiency has clearly been demonstrated, compared with H.264/AVC
There is no indication of a need to change the fundamental architecture of “conventional” hybrid video coding designs to achieve a substantial improvement
Inclusion of support of larger block sizes in a highly variable (typically tree-structured) block segmentation approach is a major common theme, although large block sizes were not found in all proposals that did well subjectively (and objectively)

The 100th MPEG Meeting Held in Suzhou, China on April 16-20, 2012?

Yu Liu — Wed, 20 Jan 2010 13:37:33 +0000

[Update]: Confirmed by MPEG official website, the 100th MPEG meeting will be indeed held in Suzhou, China on April 16-20, 2012!

The China National Body (CNNB) first proposed to hold the 100th MPEG meeting in Suzhou, China on April 16-20, 2012 during this Kyoto MPEG meeting. This proposal has a good chance of being approved by MPEG plenary if there are no other competitors. Good luck to CNNB!

Final Call for Proposals on H.NGVC/HVC Issued Jointly by VCEG and MPEG

Yu Liu — Wed, 20 Jan 2010 08:23:09 +0000

[Update]: A new email reflector, jct-vc@lists.rwth-aachen.de, is created for discussions of the new team effort. For subscription, you should follow this link: http://mailman.rwth-aachen.de/mailman/listinfo/jct-vc. Only subscribers to the list will be able to send messages to this list.

During the 39th VCEG and 91st MPEG meeting held in Kyoto, Japan on January 17-22, 2010, the call for proposals (CfP) on video compression technology (H.NGVC/HVC) will be finally issued jointly by ITU-T SG16 Q.6 (VCEG) and ISO/IEC JTC1/SC29/WG11 (MPEG) on January 22, 2010. A Joint Collaborative Team (JCT) on Video Coding Standard Development will also be established accordingly between VCEG and MPEG.

Some minor modifications to draft CfP issued in November 2009 are made. The modifications involve the timeline, test conditions and test fees, etc., as follows:

Delay the Submission of Responses to CfP on HVC, or not?

Yu Liu — Mon, 26 Oct 2009 08:31:57 +0000

In the beginning plenary of 90th MPEG meeting on Oct. 26, several national bodies, such as USNB, FRNB, SGNB, and CNNB, recommended to delay the submission date of responses to the Call for Proposal (CfP) on HVC from December 2009 to March 2010. The major concerns from the national bodies are:

the need of sufficient time to finalize the establishment of collaborative team with VCEG and only then issue a joint CfP;
the need of sufficient time to determine the cost of the subjective evaluation tests after the CfP is finalized;
the need of sufficient time to refine the CfP test conditions/materials and only then generate the proposed bitstreams;
the need of sufficient time to define the complexity evaluation criterion in an objective method for quantitative analysis,
the need of sufficient time to perform the subjective evaluation tests but currently planned in the year-end holidays period.

This recommendation aroused controversy between the delegates of national bodies and the convenor,[......]

Vote for Your Favorite Name of Next Generation Video Coding Standard

Yu Liu — Sun, 11 Oct 2009 02:31:52 +0000

As mentioned in the previous post, MPEG/VCEG has launched a new video coding standardization project, which is tentatively named as High-performance Video Coding (HVC). The formal name is still under discussion. A short list of candidates most supported in MPEG-newvid mailing list are summarized by Ken McCann from ZetaCast,

HVC – High-efficiency Video Coding (Note: not High-performance Video Coding? I prefer the latter)
EPVC – Enhanced Performance Video Coding
HEVC – High Efficiency Video Coding
HCEV – High Coding Efficiency Video

An online poll was set up at Doodle [Poll: Name of new MPEG/VCEG Standard]. Your opinion is very important. Please vote with your real name to keep the process transparent.

Future Collaboration between MPEG and VCEG

Yu Liu — Fri, 03 Jul 2009 15:42:13 +0000

As well-known, JVT (a joint video team between MPEG and VCEG) has achieved great success in the standardization of the state-of-the-art video compression, including H.264/AVC, SVC, and MVC. The academic and industry want to continue the success in the collaboration between MPEG and VCEG. Some proposals from VCEG suggest the H.NGVC (or H.265) standardization should be collaboratively done with MPEG to produce a significantly advanced video coding standard and to avoid producing multiple similar standards, which confuse the market. VCEG agrees that conducting this work jointly with MPEG will be beneficial to avoid duplication of efforts in this area. Therefore, in this MPEG London meeting, a joint meeting between MPEG and VCEG discusses the future collaboration. However, the collaboration method arouses a lot of controversy, focusing on which one of the following practical experiences should be chosen:

Practical experience 1: MPEG-2, a integrate part of video subgroup when under WG 11 a[......]

Current Status of HVC (High-Performance Video Coding) in MPEG

Yu Liu — Fri, 03 Jul 2009 12:24:54 +0000

In the last MPEG meeting, MPEG issued a Call for Evidence (CfE) on High-performance Video Coding (HVC). Nine responses to the CfE are received in this meeting (89th MPEG London). Those reponse proposals adopt typical coding tools in KTA, such as adaptive loop filter (ALF), extended macroblock size (EMS), larger transform size (LTS), internal bit depth increasing (IBDI), adaptive quantization matrix selection (AQMS), as well as new tools, such as modified intra prediction, modified de-block filter, decoder-side motion vector derviation (DMVD).

The objective experimental results show that 20% average bit reduction is achieved compared with H.264/AVC High Profile for all classes of test video sequences (Class A: 19%, Class B:25%, Class C:22%, Class D: 15% bit reductions, respectively). Subjective evalution is also conducted during this meeting. The purpose of subjective evaluation is identifying examples that give the best evidence and assessing whether the evidence is large enough. The s[......]
