Optimised source and channel coding for video transmission over ADSL

In this paper we tackle the problem of video transmission over ADSL channel. Due to the delay constraint of the transmission, the Shannon's theorem is not strictly applicable and it seems challenging to evaluate which is the contribution of joint source/channel coding. The ADSL system is standardized to work at a bit error rate (BER) of 10/sup -7/. In this work we relax this constraint in order to understand if this constraint (suitable for data transmission) is optimum also in the case of video transmission. The aim of this work is twofold: first, it jointly optimize source and channel coding in order to find out the best point of work for the overall system and second, it compares in this scenario the single and multiple description video coding approaches.
