Abstract:
A coded signal processing device for executing preselected processing with a coded signal representative of a moving picture and coded by a preselected coding system, and outputting a processed coded signal, said coded signal processing device comprising:a code storage for sequentially storing an input coded signal;a decoder for decoding the input coded signal to thereby produce an original moving picture signal;an encoder for re-encoding the moving picture signal output from said decoder by the preselected coding system;a selector for selectively outputting a coded signal output from said encoder or the coded signal read out of said code storage;a signal controller for controlling reading of the coded signal out of said code storage, output of the coded signal from said encoder, and switching of said selector, said signal controller causing said code storage or said encoder to output the coded signal based on a preselected reference synchronizing signal which is a reference for a frame synchronizing signal included in the moving picture signal while synchronizing said coded signal frame by frame, and causing said selector to select said coded signal; anda coded signal processor for executing the preselected processing with the coded signal selected by said selector to thereby process the moving picture, and outputting said coded signal in a form of a coded signal.
