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.
