A Study On the Quality Improvement Effects of Using STBC with H.264/SVC Video Transmission

Abstract

H.264/SVC is a widely used compression standard with a very high lossy compression rate. The completeness of the H.264/SVC bitstream is very crucial in achieving high quality video decompression. This is especially true in regard to the base layer which contains the important coding data. In this paper, we improve the quality of H.264/SVC video transmission by using the Space Time Block Code (STBC) technique. STBC is a technique to increase the reliability of the wireless transmission by transmitting multiple copies of the signal along multiple transmit antennas and is thus suitable for the need of H.264/SVC. We compared STBC with conventional SISO and MIMO techniques using the IEEE 802.11ac standard. The simulation results show that our method which uses STBC has superior performance in terms of both of high PSNR and low BER.
