System and method for high resolution video compression by tiling

摘要

A system and method for communicating a high-resolution image represented by a digital video signal divide the image into a number of tiles (60) which are independently digitally encoded and multiplexed (80) to produce the digital video signal which is characterized by a substantially constant serial bitstream rate. A complexity measure (70) indicative of spatial frequency content of each tile may be used to provide a rate control signal for each encoder. The present invention utilizes standard encoders and decoders to implement a high-resolution video communication system capable of transmitting a digital video signal over a single transmission channel.
