Abstract
A novel method of detecting local impairment of the coded picture caused by transmission failure on digital television transmission using a reduced reference framework is proposed. The method utilizes the SSSWHT method, which is based on spread spectrum and extraction of WHT coefficients, and precisely estimates the MSE in a small region within the frame using reduced references to detect local impairment caused by MPEG bitstream error. Computer simulations show that the proposed method detects the impaired frames completely at a reference path bitrate of 425 kbps. The method also detects slices that have impaired pixel blocks with accuracy of approximately 70% at a reference path bitrate of 425 kbps. These results confirm that the proposed method is effective for television transmission monitoring.
