Abstract:
A method and system are provided to minimize the size and complexity of bitstreams associated with encoded data by using a new compression scheme. An entropy encoder receives a list of run/data value pairs and entropy encodes separately the runs and data values, selecting their codewords according to length and magnitude, respectively, and catenates the resulting codeword pairs—run codeword first—in an encoded bitstream.
