Özet

We combine an optimal filtering approach with a multiple description coding (MDC) approach to enhance the quality of video at the receiver. Optimal filter coefficients are computed at the encoder and added to each description. At the decoder, optimal filter coefficients are obtained directly from the bit stream and employed to improve the quality. Experimental results show that the proposed approach enables better MDC performance for video in case of packet losses. (C) 2009 SPIE and IS&T. [DOI: 10.1117/1.3247861]
