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 made 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.;Monitoring information such as a picture image or sound from a monitored object (10) is transmitted for a discrimination of the information, a number of cells transmitted as data is monitored at the receiving side (20), and a variation of the number of cells is treated as a change in the state of the monitored object.
