Decoding system for decoding video signals.

摘要

A decoding system for decoding encoded video signals by transforming the video signal into reference frames and dependent frames placed between them. The display information of the reference frames is obtained from the encoder and is used to predict the display information in the dependent frames. The encoder generates and outputs a prediction error signal for each dependent frame which corresponds to the difference between the predicted and actual display information. The decoding system is provided with decoding means for receiving and decoding the encoded reference frames and the prediction error signal for the dependent frames and with processing means for reconstructing the display information for each dependent frame from the corresponding prediction error signal together with the reference frames preceding and succeeding the dependent frame being reconstructed.
