With the development of wireless network and multimedia technology

error control technology in video coding and video transmission over lossy channels has been widely studied. This paper reviewed the error-resilient coding and transmission technology

including encoder based error resilience

decoder based error concealment

network based error control and joint source and channel coding. In error resilience

redundant information is added into the bitsream to confine the error propagation. Error concealment estimates or recovers the losing data making use of the character that most nature scenes change smoothly between neighbor blocks. Network based error control

joint source and channel coding utilize the channel feedback information to guide the encoder to make an optimum decision. Additionally

error resilient tools in the latest video coding standard H. 264/AVC and the preview of the future error resilient technology are also considered. Experiments indicate that the proposed error resilient methods are effective in video transmission over lossy channels.
