Video-on-demand system with program relocation center
First Claim
1. A video-on-demand system for providing video signals from a video information provider to any one of a plurality of subscriber terminals, comprising:
- a plurality of video storage devices distributed over a network area for storing one or more video programs supplied from said video information provider;
a database;
a video gateway for receiving subscriber requests from said subscriber terminals,a service request monitor for analyzing subscriber requests received by the video gateway to produce a list of recorded calls;
a program relocator for analyzing said list to identify a first video storage device and selectively identifying a second video storage device between which said video program is to be transferred;
a transfer command generator responsive to said program relocator for producing a program transfer command signal, said video gateway being responsive to the program transfer command signal for updating said database; and
a switched telecommunication network responsive to said program transfer command signal for transferring said video programs from the first video storage device to the second video storage device.

Abstract
A video-on-demand system provides video signals from a video information provider to any one of subscriber terminals. The system comprises video storage devices distributed over a network area for storing a video program supplied from the video information provider. A video gateway receives a subscriber request from a subscriber terminal and produces a control signal according to the information stored in a database. A service request monitor analyzes subscriber requests received by the video gateway to produce a list of recorded calls. A program relocator analyzes the list to determine first and second video storage devices between which the video program is to be transferred. A transfer command generator is responsive to the determined video storage devices for supplying a program transfer command signal to the video gateway for updating the database. A switched telecommunication network is responsive to the program transfer command signal for transferring the video program from the first video storage device to the second video storage device and responsive to the control signal for establishing a connection between the subscriber terminal and the second video storage device,

5. In a video-on-demand system for providing video signals from a video information provider to any one of a plurality of subscriber terminals, comprising, a plurality of video storage devices for storing a copy of a video program supplied from said video information provider, a database, a video gateway for receiving a subscriber request from one of said subscriber terminals, said plurality of video storage devices being respectively located in video service nodes which are distributed over a network area and interconnected by links through a switched telecommunication network,
a method for relocating said copy of video program, comprising the steps of: -
a) analyzing subscriber requests received by the video gateway to produce a list of recorded calls, b) analyzing said list to identify a first video storage device and select a second video storage device between which said video program is to be transferred; c) producing a program transfer command signal depending upon the identification of said first and second storage devices; and d) supplying said program transfer command signal to said switched telecommunication network so that said video program is transferred from the fist video storage device to the second video storage device said video gateway for updating said database. - View Dependent Claims (6)
