Method for packet transmission using packet retransmission requests, and mechanism for controlling transmission of such requests

摘要

The transmission system has a transmitter and receiver with packet transmission (Pi) with a means of detecting lost packets (Pk-j) as a function of the label of importance (ILk-j) associated with the packet. The transmitter transmits one or several importance levels relative to other packets and the receiver has a mechanism recovering the packets relative to the importance of the last packet to the packet received.
