ABSTRACT:
A method of transmitting a video signal includes separating one or more parts of the video signal into a high frequency component and a low frequency component, encoding the low frequency component using an adaptive delta modulation process and transmitting the encoded low frequency components during non-active intervals of the high frequency component. In one embodiment, the high frequency component is encoded using an entropy code. A receiver is provided for reconstructing a video signal in response to the received encoded signals.
