This contribution proposes an Intra TMP fusion probing method to select a fusion candidate with minimum probing cost from a fusion candidate list. The probing cost is derived as the SAD between the reference and current block’s probing lines. The simulation results on top of ECM-10.0 are summarized as follows:

AI(Y/U/V): -0.09%/ -0.04%/ -0.11%, EncT 102.1%, DecT 101.5%

It was asked why there is a 2% runtime increase. According to the proponent, there are two factors that could cause the runtime increase: the calculation of the probing cost, and an additional RDO that is conditionally triggered.

Encoding time should be further reduced to provide better tradeoff.

Several experts expressed interest in studying this in an EE.

It was agreed to investigate this in an EE, and a better performance vs. runtime tradeoff should be investigated.
