QT/BT/TT Split Constraint Syntax Elements Signaling Method
Abstract
A mechanism is proposed to enable overriding of the split constraint syntax elements in the slice header. According to the proposal syntax elements that are used in the derivation of minimum quadtree split size, maximum binary tree split size and maximum multi-type tree split depth are signalled in the SPS and can be overridden in the slice header. It is asserted that the proposed mechanism provides more flexibility for encoders to adapt to the scene characteristics and to encoding time limitations.
JVET-L0678 QT/BT/TT Split Constraint Syntax Elements Signalling Method [H. Gao, S. Esenlik, J. Chen, B. Wang, A. M. Kotra (Huawei), M. Park, M. W. Park, K. Choi (Samsung)] [late]
Text-wise, this was considered OK, confirmed by B. Bross. The split constraints in the CTC were agreed not to be changed, but the encoder needs to be modified to signal them.
Decision: Adopt JVET-L0678.
