Method and apparatus for MPEG encoding 

                                         Abstract

MPEG compression for video/audio data is completed in real- or better
than real-time by using computer processors in thousands of television
receiver set-top boxes interconnected to a cable television network. The
set-top boxes form a massively parallel, distributed computer network.
MPEG compression for video/audio services is completed by partitioning
the processing of video/audio frames into subtasks, and distributing
these subtasks to set-top boxes which are not being used for subscriber
services. After compression, the compressed video/audio frames are
collected from the set-top boxes and are reconstructed into a compressed
video/audio stream in the proper temporal order.
