Abstract:
A switched digital broadcast network having real-time encoding and decoding of video signals for multi-point routing in an ATM network and automated central control and testing of the video signals with a high level of security and protection of signal content, comprising:a switch packet network having multiple gateways, each gateway receiving video signals in analog form from a plurality of video signal sources and comprising: an analog/digital video switch coupled to an encoder for receiving and distributing the video signals in packet form; a multiplexer coupled to the encoder for inserting the digital packets into the ATM network through a digital switch, the digital switch and multiplexer encoding destination address information into the digital packets to ensure proper routing; a de-multiplexer and decoder coupled to the digital switch for receiving and separating the digital packets from the digital switch into individual video streams subsequently decoded into analog video for distribution to the video sinks through the analog/digital video switch; and a network test manager including an in-service test executive, an out of service test executive, and a video feed monitor running continuously for automated central control of all aspect of network testing and monitoring of the video signals; each of the test executives controllable from a manual test console.
