Abstract
A method and system for generating compressed image signal. The system generates an analog image signal corresponding to the image, generates unencoded three-component image data from the analog image signal, and encodes the unencoded image data. After encoding, the image data has an OPERATING SYSTEM header, a BITSTREAM header, a Y-COMPONENT DATA field, a U-COMPONENT DATA field, and a V-COMPONENT DATA field. Each of the DATA fields has a four-byte MC VECTOR COUNT field, an MC VECTORS field, and an ENCODED DATA field that has interleaved binary tree codes and region codes. The system also stores the OPERATING SYSTEM header, BITSTREAM header, Y-COMPONENT DATA field, U-COMPONENT DATA field, and V-COMPONENT DATA field. In a preferred embodiment, the invention generates compressed video signals.
