9, the encoder is able to adjust the amount of intra refresh according to the network error conditions and the available bit rate. This intra refresh method typically increases the intra refresh for the more complex MBs, which are those typically more difficult to conceal. The main problem of this approach is that it does not guarantee that all MBs in the scene are refreshed. 7 for the Foreman sequence, where the right image represents the relative amount of MB intra refresh along the sequence (lighter blocks mean more intra refresh).

3 General Concept The theorems of Slepian–Wolf and Wyner–Ziv apply to DSC, and therefore also to the specific case of DVC. Basically, the theorems indicate that a DVC system should be able to achieve the same compression performance as a conventional video compression system. However, the proofs do not provide insights on how to actually construct such a system. As a result, the first DVC systems have appeared in the scientific literature only about 30 years later. The common approach in the design of a DVC system is to consider Y as being a corrupted version of X.
