Abstract:- In this paper a new error detection algorithm, based on a new statistical algorithm, Statistical Parity Pair Embedding (SPPE) has been proposed and implemented. They are the pairs of high and low frequency signals which forced to be correlated in term of same parity. The way to correlate them is by embedding the parity of the low frequency coefficient into the corresponding high frequency coefficient. This SPPE algorithm has been proved to have better performance than other traditional algorithms and is very suitable for using in multipoint communications since we do not need to add any extra information into the video in order to detect the errors correctly. Key-Words:- MPEG-2, video compression, error detection. 1
