Outcomes from the 101st MPEG Meeting Hosted by Ericsson
The 101st Moving Picture Experts Group (MPEG) meeting, organized by Visual Technology at Ericsson Research, was held two weeks ago in Stockholm. 450 persons from 26 countries attended.
High-Efficiency Video Coding (HEVC) was the main focus and was issued as a Draft International Standard (DIS) with substantial compression efficiency over AVC, in particular for higher resolutions where the average savings are around 50%.
MPEG and ITU-T established a new Joint Collaborative Team on 3D Video Coding (JCT-3V) that handles all 3D video extensions to HEVC as well as AVC.
Here are some of the other results from the meeting:
- HEVC Scalable Video Coding (SVC) was addressed in a public Call for Proposals issued by MPEG and ITU-T. Scalability modes in the temporal, spatial and fidelity domains will be considered and evaluated at the October meeting where a starting point for standardizing scalable coding is expected to be defined.
- Royalty-free video: Web Video Coding (WebVC), a pruned version of AVC baseline profile (decodable by AVC decoders) has passed the Committee Draft (CD) stage and is considered technically stable. The progression to DIS is put on hold until the IPR situation is clarified.
- Dynamic Adaptive Streaming over HTTP (DASH) receives a lot of attention in the industry, in particular due to the DASH Promoters Group (soon Industry Forum). There is a draft amendment developed in MPEG which now includes server events. Conformance and reference software as well as implementation guidelines are on their way.
- MPEG Media Transport (MMT) was issued as a Committee Draft (CD). It defines a new system layer including content model, delivery, cross-layer interface, and signaling.
- File formats: The fourth Edition of the ISO base media file format was published during the meeting. This is the basis for MP4, 3GP files. A Study text of the HEVC file format was issued as well as working drafts for carriage of timed text (SMPTE TTML and W3C VTT).
- 3D Audio was highlighted in a workshop open to the public at the Stockholm meeting. Industry panelists from BBC, NHK, Auro Technologies and DTS talked about the future needs for 3D audio in audio production, broadcast and gaming. MPEG will issue a Call for Proposals on 3D Audio at the October meeting with responses due in April 2013.
- MPEG Frame Compatible (MFC), targeting full resolution enhancement of AVC-based frame-compatible stereoscopic video, moved on after a period of low activity. A Call for Proposals was issued with responses due in September 2012.
