Abstract:
A system for controlling the source coding of a digital video signal by a video encoder, the digital video signal being encoded by the video encoder in accordance with predetermined encoding parameters so as to provide an encoded video data signal for transmission by means of a radio frequency communication signal by a first radio communication device to a second radio communication device, the radio frequency communication signal being received at the second radio communication device, the system comprising:means for monitoring at least one parameter indicative of a property of the radio frequency communication signal received at the second radio communication device; means for forming a feed back signal responsive to the at least one monitored parameter for controlling at least one of the predetermined encoding parameters used by the video encoder in the source coding of the digital video signal; means for transmitting the feedback signal from the second radio communication device to the first radio communication device; means for receiving the feedback signal at the first radio communication device; means for providing the feedback signal received at the first radio communication device to the video encoder; and means for modifying at least one of the pre-determined encoding parameters used by the video encoder in the source coding of the digital video signal.
