Abstract

An encoding apparatus and coding methods. The method includes receiving a video frame including screen content, generating a block containing an index map of colors for screen content in the video frame, wherein the block includes strings of index values, encoding one or multiple consecutive index values in a first string of index values using same escape colors index values and a run value identifying how many of the same escape color index values have been consecutively encoded, where the escape colors index values represent escape colors, and where the escape colors are colors not included in a palette corresponding to the block, sequentially encoding the escape colors corresponding to the one or multiple consecutive index values after all of the strings of index values of the block have been encoded, and transmitting the strings of index values and the escape colors in a bitstream to a decoding apparatus.
