In this article, a prescription-based error concealment (PEC) technique, based on a three-stage (diagnosis, prescription, and remedy) process, is proposed for video transmission on error-prone channels. A prescription is meant to be the best error concealment scheme among several pre-chosen ones, which are evaluated at encoder side for each MB. The collection of prescriptions for each frame is compressed and transmitted through a reliable channel to provide flexible and better error-recovery performance at decoder side. Experimental results show that the proposed PEC method is capable of achieving a PSNR improvement of up to 1.5dB, with respect to the best single-mode scheme, when video bit rate and PER (packet error rate) are up to 512kbps and 20%, respectively, whereas only a small amount of overheads (i.e., the coded prescriptions) is generated for reliable transmission.
