Abstract:
1. A method of transmitting video data related to a sequence of video frames, comprising: encoding a current video frame in said sequence according to a first predictive encoding to generate encoded video data, the encoded video data comprising a prediction error based on a difference between a portion of the current video frame and a first predictor of said portion of the current video frame, the first predictor being derived from a first preceding video frame in said sequence; generating auxiliary video data related to said portion of the current video frame, said generating auxiliary video data comprising calculating a correlation between the first predictor and a predetermined second predictor, the second predictor being derived from a second preceding video frame that precedes the first preceding video frame in said sequence; transmitting the encoded video data to a receiver over a first channel; and transmitting the auxiliary video data to the receiver over a second channel.
