| JCTVC-O0020 JCT-VC AHG Report: Multi-layer hypothetical reference decoder (AHG20) [K. Suehring, A. Tabatabai, S. Deshpande, M. M. Hannuksela, J. Kan, A. K. Ramasubramnian]
There was light email traffic and discussions, total 3, mainly to capture and clarify the essence of problem and issues being addressed and whether in sync with the AHG20 mandate?
Besides, some discussions, on HEVC multilayer delivery, took place during USNB meeting Oct. 1 – 3, at Apple campus. Statement shown below reflects USNB position regarding HEVC Multi-layer delivery:
The USNB of WG 11 requested for HEVC multi-layer extension plans to be harmonized with systems specifications such that some operation mode(s) are enabled with a layer-specific buffer flow model rather than a whole-bitstream buffer flow model, and bitstream multiplexing and picture association are established using system-level functionality rather than multiplexing within a single video bitstream. Operation with an AVC base layer and an HEVC scalability enhancement layer should also be supported
Four related input contributions were noted.
O0021 AHG21 Best-effort decoding with reduced decoding complexity
Reviewed Thu 31st morning (GJS).
A contribution on the topic that summarizes the previous work, provides some new data for a 12-bit process, and provides very high level specification text is provided in JCTVC-O0043.
JCTVC-O0022 JCT-VC AHG Report: Test sequence material (AHG22) [T. Suzuki, R. Chen, T. K. Tan, S. Wenger]
Intention to maintain a document which lists test sequences, licensing conditions etc..
Existing and newly offered test sequences were described in the report. Six relevant contributions and two checks of coding performance were identified.
Gathering information on licensing statements for test material would be beneficial.
Viewing of test sequences was suggested during this meeting.
