Abstract :
When multi-path fading and interference frequently disrupts a mobile radio communication system, it can seriously undermine its reliability for transmission of compressed video signals. In this paper, we present a pixel interlacing based video transmission system for low-complexity Intra-frame error concealment over error-prone mobile networks, especially under severe channel conditions. The proposed method, despite its low-complexity which is based on a simple pixel interlacing technique at the encoder, can significantly enhance the quality of the corrupted video signal. Experimental results show that the proposed method can significantly improve image quality (with the average PSNR gain up to 15.80 dB) in comparison with the existing methods.
