Abstract: A recently proposed Intelligent Pixel Mobile Multimedia Communicator
(lPM
3
C) 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 M
3
C.
