A technique for high capacity data hiding in MPEG-2 streams is presented data hiding techniques to reduce the signaling information resulting from an improvement of Inter-coding.. The objective is to maximize the payload while keeping robustness and simplicity by transforming the co-efficient. The authors propose a robust error resilient approach for MPEG video transmission over internet. In this paper, they develop an error resilient video encoding approach to help error concealment at the decoder and the modification is performed via rate-distortion optimization.
