Abstract
The differential value of the adjacent pixels is calculated firstly and is coded by a VLC coding. The VLC coding includes codes representing the Quotient and Remainder with a marker bit inserted in between. The divider is predicted with no code in the coded data stream. If three pixel components are presented in the same clock time, three VLC encoders and three VLD decoders are applied to encode and decode one pixel at a time. During encoding, both Remainder and Quotient of the same pixel component are encoded in parallel followed. During decoding, both Remainder and Quotient of the same pixel component are decoded in parallel and the results of the first pixel component are used a reference to decode the second pixel component which adopts the same decoding procedure and the decoded results of the second pixel component is used as reference to decode the third pixel component.
