Massively Parallel Intelligent Pixel Implementation of a Zerotree Entropy Video Codec for Multimedia Communications

A recently proposed Intelligent Pixel Mobile Multimedia Communicator (lPM3C) integrates the capture, encoding, decoding and display of optical images into a single array of Intelligent Pixel (IP) processors. The real-time video processing required both for compression of the captured images and decompression of the received data stream presents a significant challenge for the required pixel based coding. This paper presents an architecture for the implementation of a massively parallel wavelet based zerotree entropy video codec, designed for implementation on the IP array, capable of fulfilling the very low bit-rate coding requirements for M3C.
