Abstract:
An encoding apparatus includes a processor configured to receive a video frame including screen content and generate a block containing an index map of colors for screen content in the video frame. The block includes a first string of index values and a second string of the index values immediately below the first string. The processor is also configured to encode a second string palette_run_type flag corresponding to the second string without referencing a first string palette_run_type flag corresponding to the first string and using a single available context. A transmitter operably coupled to the processor is configured to transmit the second string palette_run_type flag in a bitstream to a decoding apparatus.
