7.1SVC bit depth, gamut, and chroma format scalability
Remarks made in this discussion include the following:
How ready is the market for such a thing?
Display technology development is not mature.
Need ability to demonstrate benefits clearly.
Need good testing conditions for experiments, etc.
Need display capability for standard development.
SVC would be just an efficiency improvement of something that can be done already in another way.
7.2MVC profiles and levels
JVT-Z049-B was reviewed and the following topics were further discussed with decisions as recorded below:
Use a constraint set flag with Main/High profile values to indicate compatibility with MVC. JVT decision: Agreed.
How do we specify the memory capacity? Use a fixed multiplier of buffering capacity and maximum ref_idx value, associated with a nominal number of views expected in the profile. The fixed multiplier should be 2. JVT decision: Agreed.
View random access friendliness constraint / parallel-processing friendliness constraint: Editors to put their best effort into the draft – others can review and comment as things move forward. JVT decision: Agreed.
Should we have a slice size constraint like we have in the "professional" profiles? Yes. JVT decision: Agreed.
