The Joint Collaborative Team on Video Coding (jct-vc) of itu-t wp3/16 and iso/iec jtc 1/ sc 29/ wg 11 held its tenth meeting during 11-20 July 2012 at the City Conference Centre (ccc), a k. a

JCTVC-J0460 AHG10: Mental cross-check of JCTVC-J0075 [Y.-K. Wang (Qualcomm)] [late]
JCTVC-J0114 AHG10: On video parameter set [Y. Chen, Y.-K. Wang (Qualcomm)]

The video parameter set (VPS) was adopted into HEVC, and includes mainly sequence-level temporal scalability related information. This document proposes a changed VPS syntax as well as the corresponding changes in SPS (including VUI) and slice header syntaxes, to enable the use of VPS in session negotiation as well as to reduce the number of bits needed for the representation of SPSs. It is asserted that since SPSs in many application scenarios are transmitted out-of-band, which means the smaller the overall size of all the SPSs the shorter the initial delay, as out-of-band transmission is reliable at the cost of increased initial delay in error-prone environment. An example design of the VPS for future extensions based on the VPS proposed in this document is included in JCTVC-J0124.

The contribution suggests that it is reasonable to minimize the size of VPS data (and SPS data).

The proposal includes making VPS fundamental to the base layer.

The design intent issue of making the VPS be a system-level characteristics description versus being decoding configuration data was discussed.

A concept predicting data between VPS and SPS was discussed.

This was resolved as recorded in actions responding to BoG on VPS (J0550).
