Channel-optimized video coding for low-power wireless applications

Abstract: This paper presents an error-robust channel-optimized coding algorithm for the transmission of low-rate video over wireless channels. The proposed coder uses a robust channel-optimized trellis-coded quantization (COTCQ) stage that is designed to optimize the image coding based on the channel characteristics. The resilience to channel errors is obtained without the use of channel coding or error concealment techniques. Additionally, a novel adaptive classification scheme is employed, which eliminates the need f… Show more
