| JCTVC-M0181 SEI message: independently decodable regions based on tiles [Y. Ye, Y. He, Y. He (InterDigital), X. Yang, P. Yue, Y. Zhang (Huawei), M. Horowitz (eBrisk Video)]
Chaired by J. Boyce.
This is a follow-up proposal to JCTVC-L0049, JCTVC-K0116 and JCTVC-K0248. At the 11th and 12th JCT-VC meetings, it was proposed to add an SEI message to support independently decodable regions using tiles. Simulation results of the proposed SEI message showed that, for typical use case scenarios, the restrictions on motion compensated prediction as required by the proposed SEI message incur RD performance penalty of 1.4% and 2.5% when loop filter across tile boundary is disabled and enabled, respectively. Subjective viewing of the reconstructed video did not reveal noticeable coding artefacts.
Address tiles only, not slices.
Identifies tile regions, and explicitly lists which tiles are contained within the region.
Some experimental results provided at QP = 22 only.
Refer to discussion in JCTVC-M0235.
