Abstract

A system for adding monitoring capability to equipment located within a video, audio and/or data production facility. A sampling device is connected to a data communications network and transmits a continuous representation of the video, audio or data being sampled over a data communications network in response to commands from an operator station. To accommodate monitoring of large numbers of sampling devices on a single network, the sampling device may encode and/or compress the video, audio or data being monitored prior to transmitting the sample over the network. The sampling device may also further reduce its contribution to network loading by providing an instant sample of the stream being sampled, such as a single video frame, either a single time, or repeatedly at regular predetermined time intervals.

Claims

1. A data monitoring system comprising

a signal processing block,

at least one output connected to said processing block,

a compressor connected to said output of said processing block, and

a data network connected to said compressor and to at least one monitoring station,

whereby said monitoring station receives an output of said compressor in order to monitor the output of said signal processing block.

2. The data monitoring system of claim 1, wherein signals received by said data network are controlled by commands transmitted from said data network.

3. A television monitoring system comprising

a television signal processing block,

at least one output connected to said processing block,

a video compressor connected to said output of said processing block, and

a data network connected to said video compressor and to at least one monitoring station,

whereby said monitoring station receives an output of said video compressor in order to monitor the output of said signal processing block.

4. The television monitoring system of claim 3, wherein signals received by said data network are controlled by commands transmitted from said data network.

5. A television monitoring system comprising

a television signal processing block,

at least one video output connected to said processing block,

a video compressor connected to said video output,

at least one audio output connected to said processing block,

an audio compressor connected to said audio output, and

a data network connected to said video compressor and said audio compressor,

and to at least one monitoring station

whereby the data network receives outputs of said video compressor and said audio compressor in order to monitor outputs of said signal processing block.

6. The television monitoring system of claim 5, wherein signals received by said data network are controlled by commands transmitted from said data network.
