Embodiment Construction

[0024] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] The present invention provides a transmission control scheme for video data. In this scheme, the transmission of video data to be transmitted is controlled in combination with the encoding rate of video data during encoding and the token shaping algorithm, which can reduce traffic fluctuations in the transmission process, reduce Data Loss Risk.

[0026] The video data transmission control scheme of the present invention is mainly applied to video stream transmission when users watch videos online, and can improve the user's video viewing experience by controlling the fluctuation of video streams during the transmission process. like figure 1 As shown, the vid...

Abstract

The invention discloses a transmission control method of video data. The method comprises the steps as follows: obtaining the video data to be transmitted and code rate of the video data; generating a token with a preset rate and placing the token in a token container, wherein the token capacity in the token controller is adaptively adjusted according to the maximum code rate of the video data to be transmitted; controlling the transmission of the video data to be transmitted according to the token in the token container. The invention further discloses a transmission control device of the video data. The method and the device of the invention improve the flow shaping efficiency in the transmission process of the video data.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a video data transmission control method and device. Background technique [0002] During the encoding process of video image data, often due to the change of the recording scene, such as switching from a static scene to a moving scene, the bit rate of the encoded video stream fluctuates greatly. During network transmission, fluctuations in the bit rate of the video stream will cause instantaneous traffic fluctuations and increase the risk of data loss. Therefore, it is necessary to perform traffic shaping on the encoded video stream during transmission. [0003] In the prior art, a constant encoding rate is set during encoding to encode video image data. In this way, image details will be lost, and traffic shaping efficiency will be low. Contents of the invention [0004] The main purpose of the embodiments of the present invention is to provide a video data transmission co...
