Communication system, transmitter, receiver and method for using a descriptor of data being saved. RU patent 2280960.

FIELD: engineering of communication system between transmitter and receiver, where transmitter sends digital data and data descriptors to receiver via communication channel.

SUBSTANCE: communication system provides identification of multiply used data in transmitter by means of data descriptors, inserted into data stream being transferred from transmitter to receiver, data stream, being received at receiving end, is analyzed to detect presence of data descriptors, which signify presence of multiple use data, when such a descriptor is detected, it is locally saved at receiver level jointly with data to which it is related, and multiple use data saved in such a way may be utilized not only immediately after receipt at receiving end, but also later, without need to request transmission from the transmitter.

EFFECT: decreased load on transfer channel.
