Abstract:
An apparatus for statistically multiplexing a plurality of video signals, said apparatus comprising:a first complexity detector coupled to receive a first video signal having a complexity which varies over time, said first complexity detector generating a first complexity signal which relates to said complexity of said first video signal;a second complexity detector coupled to receive a second video signal having a complexity which varies over time, said second complexity detector generating a second complexity signal which relates to said complexity of said second video signal;a first encoder for compressing said first video signal at a variable compression rate to generate a first compressed video signal;a second encoder for compressing said second video signal at a variable compression rate to generate a second compressed video signal;a controller for controlling said variable compression rates of said first and second encoders based on said first and second complexity signals; anda multiplexer coupled to receive said first and second compressed video signals.
