Abstract

This paper introduces a new three descriptions data transmission for multiple description scalar quantization (MDSQ) system using the designed index assignment of k = 2. This paper focus on improving the reconstructed image in terms of PSNR for the central decoder and to reduce the central distortion. Analysis of the system with different value of k is also carried out. The three descriptions system requires three encoders and at the receiver requires one central decoder and six side decoders. Simulation results show that the performance of the proposed three description MDSQ scheme out performs the ordinary two descriptions MDSQ scheme.
