ABSTRACT:
This invention relates to an image reproduction apparatus for performing video signal processing by utilizing a plurality of DSPs. A digital video signal is supplied to a DSP signal processor constituted by combining the plurality of DSPs, and programs to be supplied to the plurality of DSPs are time-divisionally switched on the basis of a transmission timing of the video signal, so that the DSP signal processor can execute a plurality of systems of processing operations, and many functions can be added without increasing a circuit scale.
