Telemetry monitoring method and device therefor for transmitting information by means of asynchronous transfer mode technique in broadband ISDN

摘要

A telemetry supervisory system in an asynchronous transmission mode network which discriminates less information when less variation rates occur and more information when more variation rates occur, and provides a transmission system for transmitting the discriminated information as a cell having a fixed length, includes an object detecting and monitoring device, a coder for coding picture signals from the detecting and monitoring device, a transmission unit which changes the output of the coder into cells each having a fixed length and a monitor station. Monitoring information such as a picture image or sound from a monitored object is transmitted by the transmission unit for a discrimination of the information. A number of cells transmitted as data is monitored at the receiving side, e.g. monitor station, and a variation of the number of cells is treated as a change in the state of the monitored object.
