Paper Abstract

This paper presents an effective and simple video decoding and simple video decoding method in H.263 over noisy channels without use of any kind of feedback information. We address that through the computer simulations the negotiable options of H.263 are of not use for error-robustness against error-prone channel, and propose one of easy error detection/correction methods. The key idea is that sacrifice of coding efficiency by restricting some functionalities of H.263 reduces the number of a set of possible administrative information, which allows a decoder to easily check whether or not the desirable syntax has been obtained and to try syntax correction. Applying this method, for example, syntax errors such as 'MCBPC' errors can be easily detected and corrected, which are crucial for removing visually annoying 'green/pink' block artifacts completely. Since the proposed method is completely H/263-compatible, the decoder is very good at finding H.263 syntax errors caused by channel errors. The channel model we have chosen was DECT2 with bit- error-rate of 2.1 X 10-3.
