Abstract
Incoming decoded data (1), for example from an H264 decoder, is fed to an encoder unit (2) that entropy encodes the decoded data using a parallel encoding scheme that includes context-based arithmetic encoding. The syntax is chosen so that the context does not depend on the immediately previously encoded symbol. The output of the encoder (2) is fed to a FIFO memory whose output is fed to a complimentary decoder (4) whose output produces a delayed copy of the incoming decoded data (1).
