| JCTVC-M0204 Ultra-low delay multi-layer decoding by interleaving of decoding units in SHVC and 3D/MV-HEVC [K. Sühring, R. Skupin, Y. Sanchez, T. Schierl (Fraunhofer HHI)]
(Presented initially in joint discussion with JCT-3V Sat 20th pm, but not closed in that discussion.)
Discussed in BoG; see BoG report M0450.
The contribution proposes to allow a bitstream layout that enables multi-layer ultra-low delay decoding operation by parallel decoding of pictures. Decoding units belonging to different layers/views would be allowed to be interleaved within an access unit. The order is constrained in a way that all necessary reference layer/view data shall be available before sending an enhancement layer decoding unit. In addition this contribution proposes a clarification on the definition of access units and coded pictures in multi-layer coding environments.
A definition of access unit was adopted that can make this feasible. Consideration of whether to allow mixing of NAL units of different layers, ordering constraints within such a mixture, and any additional HLS needs to support this are for further study.
M0464 was submitted toward resolving this.
