Because the hybrid decoder is configured for input port 16 on the matrix switch, ISP_1
instructs the matrix switch to switch video from port 16 to the monitor that is selected (switch
video input #16 to monitor #1). The monitor displays the recorded video on Monitor 1.
ISP_1 waits for user input and processes features such as fast-forward and rewind. When an
operator presses a key sequence to stop the digital video, ISP_1 instructs the hybrid decoder to
terminate the session with ISP_2 and instructs the matrix switch to resume live video from camera
5 to monitor 1.
Note:
Tests in a lab environment show that the average retrieval time for playback video is
approximately 1.5 seconds and that it takes approximately one second to go back to live viewing
after an operator stops digital playback.
