Abstract

The transmission of video over wireless is a particularly involved problem-requiring as it does the transmission of a variable length highly compressed, delay-sensitive stream over an error prone medium. In this paper, this problem is addressed within the multiple description coding paradigm. In particular the problem of wireless video conferencing over a constant bit-rate channel is addressed. A low-complexity, low-delay adaptive coder that uses multiple description coding to combat channel errors is proposed. Error propagation is curtailed by using a leaky prediction mechanism. A low-complexity rate control scheme based on the LMS algorithm is also proposed.
