Abstract:
1. A method of moving video data thru a video-on-demand system to a viewer network, where said system includes—1) a digital computer which is coupled to a random access memory that stores an operating system program, 2) a disk which is coupled to said digital computer that stores a video server program as well as other programs which are paged into and out of said memory by said operating system program, and 3) a network interface circuit which intercouples both said memory and said computer to said viewer network; said method including the steps of: segregating, from use by said operating system program, a hidden section of said memory; writing video data into said hidden section of said memory, at addresses which are selected by said video server program; sending, from said video server program to said network interface circuit, messages which identify said selected addresses; issuing read commands to said memory, directly from said network interface circuit and independent of any program in said hidden section of said memory, which request said video data at said selected addresses; and, receiving said video data in said network interface circuit directly from said hidden section of said memory in response to said read commands and independent of any program in said hidden section of said memory.
