Test A.2 – Run coding for two-colour palette – withdrawn
Test A.3 – Restricted run coding
Proponent: Canon, JCTVC-R0085, JCTVC-S0062

This test limits the amount of palette_run syntax element decoded for the index mode of the current palette implementation. When the colour index is larger than a threshold, the palette_run is not signalled. The issue of the parsing dependency noted for this contribution will be investigated.
Some gain was shown – 0.0 to 0.5% per source content category (all-intra).
Note: Parsing depends on reconstructed palette index values.
