ABSTRACT:
The video switch system remotely controls on a per switch, and hence a per channel, basis the insertion of a programmed channel video signal sent over one telecommunications network, a commercial video signal sent with the switch commands over another network or a locally generated video signal compiled from digitally stored video signals located on a digital storage device by insert locator data sent with the switch commands and the commercial insert video. The video switch system, in preferred embodiments, can generate a plurality of third video signals based upon a plurality of insert location information that is part of the insert locator data and apply respective third video signals to one or more of the video switches dependent upon switch commands and insert locator data generated remotely and received at the cable head end. The digitally formatted video signals can be sent to the video switch system via the second telecommunications network or via phone lines or be hand delivered on compact disc-read only memory (CD ROMs), magnetic tape, or other transportable media capable of storage of digital data.
