Abstract
To reduce the needed bandwidth of video communication system, a portion of the video image that differs from a preceding frame of the video image is predicted from the decompressed audio data with a model operating at both the transmitter and the receiver. The model accuracy is increased and the synchronisation enhanced by reducing the number of degrees of freedom of the model and by making the prediction of the next phoneme in a hierarchical manner.
