Video transmission over error-prone channels requires techniques that are efficient in compressing the video and robust against the channel errors. The application of MPEG-4 in video communication can conform to bandwidth limitations, but, on the other hand, the highly compressed bits are more susceptible to noise errors. Therefore, many researchers have been working on error concealment techniques to recover errors caused by noise. However, the errors are always assumed to have been correctly located, which is the precondition for error concealment. We propose a novel error detection technique. This scheme can effectively and efficiently detect some errors which cannot be detected traditionally. Experimental results show that the error detection ratio (EDR) for this type of error is more than 90%, even 100% sometimes.
