JCTVC-B097 [W.-J. Chien, M. Karczewicz, P. Chen (Qualcomm)] TE1: Decoder-side motion vector derivation report from Qualcomm

This contribution presented a decoder-side motion vector derivation (DMVD) scheme with a multi-hypothesis control. The DMVD scheme used in this contribution is based on the template matching prediction method described in JVT-AA040. A multi-hypothesis control flag is signaled when the DMVD mode is selected and indicates how many hypotheses are used for motion compensation. Results show an average of 5.8% gain for IPPP configuration and 3.2% gain for hierarchical B configuration.

JMKTA 2.0 context.

Remark: Complexity impact of decision-making process to decide the number of hypotheses.

Remark: Not using extended Macroblock. Somewhat weaker anchor.
