PURPOSE:To provide the information reproduction system in which different system at a remote distance to each other execute processing such as reproduction of the same dynamic image, rewinding and frame feeding synchronously with each other without use of a communication line having a sufficient transmission capacity. CONSTITUTION:A local side system 1 receives a video signal from a video deck 15, scrambles the signal to form a dynamic image data file on a hard disk 113 and sends the file to a remote system 3 through a communication line 5. The remote system stores the scrambled dynamic image file to a hard disk 313. Then the lock system 1 descrambles and reproduces the scrambled dynamic image file and sends a scramble key to descramble the file, a frame synchronizing signal and a reproduction control command such as reproduction and rewinding in real time to the remote system 3 through the communication line 5. The remote system 3 descrambles the scrambled dynamic image file according to the received information and reproduces the file synchronously with the local system. |
