Abstract

A data processing apparatus has a de-compressor and an input interface. The de-compressor de-compresses a compressed display data in an input bitstream. The input interface receives the input bitstream from another data processing apparatus via a display interface, parses indication information included in the input bitstream, and configures the de-compressor to employ a de-compression algorithm according to the indication information.
