ABSTRACT:
In video on demand (VOD) problems may be caused by potential transmission, queuing and processing delays in the network which can lead to erratic and erroneous operation of VOD systems when responding to viewer commands. This problem is overcome by employing a video frame reference number in the return signalling channel to the video server so that the command is related to the correct frame. At the same time the viewers display is halted until the revised frame is re-received so that the display is re-enabled at the correct point in the program.
