Apparatus with frame check capability for reproducing images by combining outputs of concurrently operating disk players storing portions of the images

An apparatus for reproducing images by concurrent operations of disk players, the apparatus comprising:

• means for generating a frame designation signal indicative of a frame to be reproduced;
• a plurality of disk players responsive to the frame designation signal to retrieve the frames to be reproduced and generate disk player output signals corresponding thereto and a present frame number for each frame read, said frame designation signal being common to all of said disk players;
• a synthesizing circuit to synthesize video format signals;
• relaying circuits for relaying the disk player output signals to the synthesizing circuit,
• means for comparing for coincidence the present frame number output by each of the disk players with the frame number to be reproduced as indicated by the frame designation signal and means for supplying a disable signal to a relaying circuit corresponding to a disk player for which the comparing means fails to indicate coincidence,
• the relaying circuit stopping relaying of an output signal of the disk player failing to indicate coincidence, in response to said disable signal.
