A video codec using re-transmission

摘要

A method of video decoding comprising receiving encoded video data; decoding said video data to form decoded video data and determining if the decoded video data contains an error. When it is determined that an error is present, a message is sent to a transmitting video encoder requesting an update of at least the portion of the video data containing the error wherein said update message is only sent if a pre-determined period has elapsed since a previous update message was sent. A complementary encoder is also described.
