Abstract

The invention provides a state feedback method and device of a transmission channel, belonging to the technical field of communication. The state feedback method of the transmission channel includes: determining the video data to be transmitted, and using N data packets to transmit the video data, where N is an integer greater than or equal to 1; obtaining the accumulated value of time delay and jitter of the i-th data packet, where i is greater than An integer equal to 0 and less than or equal to N; preprocess the accumulated value of delay jitter of the i-th data packet to obtain the average accumulated value of delay jitter of the i-th data packet; value and the average delay jitter accumulation value of the i-th data packet to determine the state of the transmission channel, and send the state of the transmission channel to the sending end device. The state feedback method and device of the transmission channel provided by the invention improve the transmission efficiency of video data.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for state feedback of a transmission channel. Background technique [0002] When video data is transmitted through a wireless network or a wired network, if the transmission channel is congested, it will cause packet loss, resulting in blurred or stuck video quality. To solve this problem, the packet loss rate based on RR report feedback is usually used to trigger the encoding rate adjustment of the video sending end, so as to effectively use the transmission capacity of the transmission channel and improve user perception. [0003] However, the receiver device usually detects packet loss only after the transmission channel is congested and the buffer overflows, and there is a certain delay from detecting packet loss to actually sending the RR report. Therefore, the code triggered based on the RR report packet loss rate Adaptive rate adjustment is a me...
