Abstract: We have proposed a new system architecture for an MPEG-2 video encoder designed for high-resolution video. The system architecture uses the spatially parallel encoding approach and has scalability for the target video resolution to be encoded. Three new techniques have been introduced to the system. The first is a general video interface that supports multiple video formats. The second is a bitstream generation control scheme suitable for the spatially parallel encoding approach. The third is a simple data sharing mechanism for all encoding units. With these techniques, the system achieves both scalability and high encoding efficiency. Video encoding systems based on this system architecture will enable high quality video encoding to be used for visual applications for commercial and personal use at reasonable system cost. !10
