JCTVC-B120 [F. Bossen (BoG)] Report of TMuC design BoG
A break-out session was held on July 22 from 2pm to 5pm in room T103 to discuss future TMuC software development and testing. Notes taken during the meeting were included in this document.
Settings were agreed as in that document (including the selection of InterpFilterType = 4 for the high-coding efficiency configuration), relative to JCTVC-B003 configurations, with additional notes as follows:
Three coding structures are planned to be used in experiments:
-
IBBB (without frame re-ordering and without hierarchical QP assignment among B frames)
-
Hierarchical B (as in Alpha CfP anchor) with length-8 structure (using forward-predictive B frames rather than P frames)
-
All-intra
Each of these has two complexity-level configurations, i.e. 6 configurations in total.
The configuration files were made available by Monday noon on the reflector. Hierarchical coding should be set to 0 for low delay, and NRF should be set to 0 for the low delay case.
It was decided to issue the agreed configurations as JCTVC-B300.
Experiments for intra may only use all-intra coding. Experiments for inter techniques may omit the all-intra case, but should include both of the other coding structures.
Test sequences to be used – as in the CfP.
Number of frames to be encoded: full length as used in CfP.
This also applies for cross-checking – in this context it was emphasized again that cross-checking is a serious task including more than just running software. Particularly, cross-checkers shall inspect the source code and be able to understand the implementation.
New planned integrations - agreed:
-
Modification of MV prediction in JCTVC-B094 (config issue)
-
Harmonization of intra prediction modes per JCTVC-B100
-
Rounding-related proposal JCTVC-B074 (B frame rounding control, for which verification was reported in JCTVC-B046, and more transform LSBs)
