Video transport over wireless networks

In this paper, we propose an efficient scheme to transport video over wireless networks, specifically cdma2000® 1x. Speech transmission over cdma2000® uses a variable rate voice coder (vocoder) over a channel with multiple fixed rates. We apply these ideas to compressed video transmission over wireless IP networks. Explicit Bit Rate (EBR) video compression is designed to match the video encoder output to a set of fixed channel rates. We show that in comparison with VBR video transmission over a fixed rate wireless channel, EBR video transmission provides improved error resilience, reduced latency and improved efficiency.
