COOPERATION BETWEEN PACKETIZED DATA BIT-RATE ADAPTATION AND DATA PACKET RE-TRANSMISSION

摘要

A method for improving a cooperation between a packetized data bit-rate adaptation and a data packet re­transmission transmits data packets from a server to a client with a first bit-rate; stores transmitted data packets in a server buffer; stores transmitted data packets in a client buffer; signals impairment information related to an impairment of transmitted data packets during transmitting to the server, wherein the signaled impairment information is analyzed by the server to decide if a re-transmission of data packets stored in the server buffer is required; and signals client buffer information related to a state of the client buffer to the server, wherein the client buffer information is analyzed by the server to decide if a re-transmission of data packets is required.
