JCTVC-J0308 Context index derivation method for level 0 significance map coding [K. Panusopone, W.-Y. Kung, X. Fang, L. Wang (Motorola Mobility)]

This contribution proposes to share contexts for level 0 significance map coding between 4x4 and 8x8 TUs. To reduce complexity, the proposal uses common logic to derive context index instead of using mapping table. The simulation results show that overall performance loss is less than 0.1%.

Only some implementations might draw a benefit (and even then questionable how large the benefit would be) – not justified against the loss that occurs.

No action.
