Progressive Transmission of Uncompressed Video over mmW Wireless

Abstract

In this paper we propose a new progressive rate adaptation scheme for uncompressed video over millimeter wave wireless (mmW) in which the video data rate can be adapted to any rate smoothly and with minimal video quality degradation. Two major steps: 1. Progressive pixel differential transformation (PPDT) in which difference values of pixels are compressed and transmitted in a new systematic way for progressive rate adaptation. 2. Progressive pixel dropping (PPDP) in which pixels at different positions are evenly dropped in a new systematic way for progressive rate adaptation if the data rate is still too high to fit into the available channel bandwidth after the first step. Simulation results show that our proposed rate adaptation scheme can achieve at least 20 dB quality improvement in PSNR (Peak Signal to noise ratio) than the conventional rate adaptation schemes.
