摘要：
When compressed video is transmitted through a data network, such as an ATM or a wireless network, data can be lost due to channel errors and/or congestion. Techniques that post-process the received video and conceal the errors in real-time are needed. In this paper we describe the implementation of an error concealment technique on a fixed-point digital signal processor.
