Abstract
A method of encoding non-key frame data is disclosed. The method includes forming a bit stream from the data by arranging the bits from the data in a known order. The bit stream is interleaved to form an interleaved bit stream, and parity bits are generated for each of the bit stream and the interleaved bit stream. Bits are deleted from the generated parity bits dependant upon the bit plane of those bits, and an encoded bit stream is created from the remaining parity bits.
