FEEDBACK CONTROL TO ENCODER

摘要

A method of transmitting a compressed video data stream (CVDS) generated by an encoder from a transmitter to a receiver over an end to end communications link, said end to end link including a transmit side wireless channel between the transmitter and the receiver, the method including the steps of: ascertaining a quality parameter indicative of the transmission capability of the wireless channel between the transmitter and the receiver; and at the transmitter, altering the bit rate of the compressed video data stream generated by the encoder in dependence on the quality parameter and other information.
