ABSTRACT:
An apparatus for statistically multiplexing a plurality of video signals is provided with a complexity detector, coupled to receive a pre-compressed video signal, for generating a complexity signal which relates to the complexity of the pre-compressed video signal, an encoder for compressing a non-compressed video signal at a variable compression rate to generate a compressed video signal, a controller for controlling the variable compression rate of the encoder based on the complexity signal, and a multiplexer coupled to receive the pre-compressed video signal and the compressed video signal. The apparatus may be provided in a broadcasting system, such as a satellite broadcasting system. The broadcast system may include a transmitter coupled to receive the video signals from the multiplexer, a satellite coupled to receive the video signals from the transmitter, a receiver for receiving video signals from the satellite, and one or more decoders connected to receive video signals from the receiver.
