Video data is moved thru a video-on-demand system by the following steps: a) segregating, from an operating system program, a hidden section of a random-access semiconductor memory which cannot be paged by the operating system program; b) writing video data into the hidden section of the memory at addresses which are selected by a video server application program; c) sending, from the video server application program to a network interface circuit, messages which identify the selected addresses; and d) issuing read commands, from the network interface circuit with the selected addresses as identified in the messages, which read the video data directly from the hidden section of the memory into the network interface circuit for transmission to a network.
