Banwidth Adjustment For Real-time Video Transmission

摘要

A method for bandwidth adjustment for real-time video transmission is disclosed herein. The method comprises transmitting, by a sender, a first portion of the video bitstream encoded using a current bitrate and transmitted as a series of data packets, receiving, by the sender, a back channel message from a receiver, wherein the back channel message comprises receiver-side bandwidth parameters determined by the receiver in response to receiving the series of data packets, wherein the receiver-side bandwidth parameters comprise at least one of an accumulated time difference parameter, a received bitrate parameter, a packet loss ratio parameter, a bandwidth indicator parameter, and a FEC ratio parameter, adjusting, by the sender using the processor, the current bitrate for encoding the video bitstream based on the receiver-side bandwidth parameters, and transmitting, to the receiver, a second portion of the video bitstream encoded using the adjusted current bitrate.

1. A method of adjusting bandwidth for transmitting a video bitstream to a receiver, comprising:
transmitting, by a sender, a first portion of the video bitstream encoded using a current bitrate and transmitted as a series of data packets; receiving, by the sender, a back channel message from the receiver, wherein the back channel message comprises receiver-side bandwidth parameters determined by the receiver in response to receiving the series of data packets, wherein the receiver-side bandwidth parameters comprise at least one of an accumulated time difference parameter, a received bitrate parameter, a packet loss ratio parameter, a bandwidth indicator parameter, and a FEC ratio parameter; adjusting, by the sender using the processor, the current bitrate for encoding the video bitstream based on the receiver-side bandwidth parameters; and transmitting, to the receiver, a second portion of the video bitstream encoded using the adjusted current bitrate.
