ABSTRACT:
A video broadcast system is provided with an apparatus for processing a plurality of program signals corresponding to, for example, movies or other prerecorded programs, to selectively reduce the bandwidth required to transmit or broadcast the program signals. The signal processing apparatus includes a rate controller for generating a rate reduction factor based upon the data rates of the first and second program signals, a first channel processor coupled to receive the first program signal, and a second channel processor coupled to receive the second program signal. Each of the channel processors includes a data path for selectively reducing the bit rate of the program signals based upon the rate reduction factor.
