Embodiment Construction

[0075] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0076] figure 1 It is a flowchart of a video switching method provided by an embodiment of the present invention. see figure 1 , the method includes:

[0077] 101. During the playback of the video, send a code rate switching signaling to the server, where the code rate switching signaling is used to instruct to switch the video stream data of the first code rate in the current streaming channel to the video stream of the second code rate Data, different bit rates correspond to different resolutions.

[0078] 102. Receive the video stream data of the second code rate sent by the server through the stream fetching channel.

[0079] 103. Based on the current playback channel, render the video stream data of the second bit rate.

Abstract

The invention discloses a video switching method and device, and belongs to the field of multimedia. The method comprises the steps that in a video playing process, a code rate switching signaling issent to a server, wherein the code rate switching signaling is used for instructing video stream data with a first code rate in a current stream acquisition channel to be switched to video stream datawith a second code rate; receiving the video stream data with the second code rate, sent by the server through the stream acquisition channel; and rendering the video stream data with the second coderate on the basis of a current playing channel. According to the method, one code rate switching signaling instructs the server to obtain the video stream data with different code rates, and the video stream data subjected to code rate switching is transmitted on the existing stream acquisition channel; an electronic device renders the switched video stream data based on the existing playing channel; and a new channel is not required to be established, so that the problems of resource occupation and time consumption caused by establishing the new channel are solved, the resources saved, and the switching speed of videos is improved.

Description

technical field [0001] The invention relates to the field of multimedia, in particular to a video switching method and device. Background technique [0002] During the playback of the video, the user may have a need to switch the video definition. If the user feels that the current video playback is not clear enough, the current video needs to be switched from low-definition (SD) to high-definition (HD), or, The user feels that the playback of the current video is not smooth enough, and needs to switch the current video from high-definition to low-definition. In order to meet the user's switching needs, the electronic device can provide a video definition switching function. When the user's switching operation on the video definition is detected, the electronic device can obtain the current video with different bit rates for playback according to the switching operation, thereby Realize the resolution switching of the current video, where different bit rates correspond to d...
