A video stream transmission control method and a video stream transmission control device

Abstract

The embodiment of the invention discloses a video stream transmission control method and a video stream transmission control device. The video stream transmission control method comprises the following steps of obtaining an available bandwidth of a current network; when the current speed of a teleoperation robot is not 0, determining a first code rate value of the video stream according to the current speed of the teleoperation robot, wherein the minimum code rate value of the experience requirement of a video stream receiving terminal of the teleoperation robot can be met by the first code rate value at the current speed of the teleoperation robot; and by integrating the current bandwidth of the current network and the first code rate value, adjusting the current video stream transmission bandwidth of the teleoperation robot in a way of firstly adjusting the average code rate of the video stream, so as to furthest meet the experience requirement of the video stream receiving terminal of the teleoperation robot when the current video stream transmission bandwidth of the teleoperation robot is smaller than the available bandwidth of the current network. The method and the device with the technical scheme have the advantage that the real-time performance of the video stream transmission and the experience feeling of a user can be effectively improved.

Description

technical field [0001] The invention relates to the field of streaming media, in particular to a video streaming control method and a video streaming control device. Background technique [0002] Teleoperation is an important technology for robot applications. Operators can monitor and control remote robots to complete various tasks through the teleoperation platform. [0003] With the development of the times, teleoperation robots have played an irreplaceable role in more and more fields, such as remote ward monitoring, internal management of nuclear reactors, etc., and teleoperation robots can be seen. Among them, audio and video Communication becomes an important part of teleoperating robot experience. The transmission method of audio and video plays a decisive role in the interactive experience. With the development of streaming media coding and decoding technology and high-definition television (HDTV, High Definition Television), manufacturers of teleoperated robots c...

Problems solved by technology

[0006] However, since the mobile robot often moves in the area covered by the wireless network, when the network condition changes with time, it will constantly switch the encoding method, and there will be a transition transient process of about 1 second between the switching encoding methods, which will affect the video quality. The real-time nature of streaming reduces the user experience
