Initial Bandwidth Estimation For Real-time Video Transmission

摘要

A method for initial estimation of bandwidth for real-time video transmission is disclosed herein. The method comprises encoding, by the sender using a processor, a first portion of the video bitstream comprising an I-frame, transmitting, by the sender starting from a first point in time, the encoded first portion of the video bitstream as a series of data packets having a packet size based on a predetermined encoder bitrate, receiving, by the sender and at a second point in time, a message from the receiver, wherein the received message comprises a parameter indicative of a total number of bits received by the receiver, determining, by the sender using the processor, an initial estimated bandwidth, based on the received parameter, the first and second points in time, and a round trip delay between the sender and the receiver, and transmitting, to the receiver, a second portion of the video bitstream encoded using the initial estimated bandwidth.

1. A method for estimating an initial bandwidth for transmitting a video bitstream between a sender and a receiver, comprising:
encoding, by the sender using a processor, a first portion of the video bitstream comprising an I-frame; transmitting, by the sender starting from a first point in time, the encoded first portion of the video bitstream as a series of data packets having a packet size based on a predetermined encoder bitrate; receiving, by the sender and at a second point in time, a message from the receiver, wherein the received message comprises a parameter indicative of a total number of bits received by the receiver; determining, by the sender using the processor, an initial estimated bandwidth, based on the received parameter, the first and second points in time, and a round trip delay between the sender and the receiver; and transmitting, to the receiver, a second portion of the video bitstream encoded using the initial estimated bandwidth.
