An image reproduction apparatus with a plurality of disk players which concurrently perform play operation so as to produce a plurality of division video format signal concurrently. The video format signal are combined into a signal/final video format signal. The respective frame numbers extracted from the respective division video format signals are compared with the corresponding designated frame numbers. When the extracted frame number and the designated frame number do not coincide to each other, the corresponding division video format signal is ignored in the synthesis operation for producing the final video format signal.

Apparatus with frame check capability for reproducing images by

A video format signal recording and reproducing method wherein a plurality of division video signals are obtained by dividing a single video format signal and are recorded onto a plurality of recording media, set indication ID numbers are recorded. When the division video signals are reproduced from the recording media, the set indication ID numbers are automatically discriminated. Only when the set indication ID numbers coincide each other, the reproducing operation of the single video format signal is executed.
