Abstract
A method and apparatus is described for implementing a real time video processing system based on the rationalized Haar transform. The system operates in real time to remove redundant information from video data for the purpose of compressing the video bandwidth. A digital apparatus for implementing the system is described which is capable of processing video in real time at data rates up to 60 M bits per second.
