Problems solved by technology

However, these technical solutions are all applied to specific platforms. For example, Live HTTP streaming is mainly used in the Apple ios system, and calculations are mainly based on two aspects of network fluctuations and playback buffers. The conditions for determining the optimal stream are relatively simple and cannot be completely Reflect the playback behavior of the actual player

Embodiment Construction

[0136] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0137] refer to figure 1 , which shows a flow chart of the steps of an embodiment of a code stream switching method embodiment of the present invention, which may specifically include the following steps:

[0138] Step 101, when the previous video is finished playing and the target video is continuously broadcast, or when the player is started for the first time to start playing the target video, key parameters are obtained;

[0139] The embodiment of the present invention starts with the play trigger operation of the target video. The play trigger operation of the target video may include: after the previous video has been played, the trigger operation of continuously playing the target video, or when the user starts the player f...

Abstract

The embodiment of the present invention provides a code stream switching method and a code stream switching device, wherein the method comprises the steps of obtaining a key parameter when the previous video is played, and a target video is played continuously, or when a player is started for the first time to play the target video; based on the key parameter, deciding an actual optimal code stream; when the actual optimal code stream is different from the current playing code stream, calculating a switching opportunity; and when the switching opportunity arrives, switching the current playing code stream of the target video into the actual optimal code stream. According to the present invention, the seamless and smooth switching of the two code streams can be guaranteed, and the user watch experience is improved.

Description

technical field [0001] The invention relates to the technical field of video playback, in particular to a code stream switching method and a code stream switching device. Background technique [0002] Streaming media technology refers to a technology and process of compressing a series of multimedia data and then performing real-time and continuous transmission of multimedia data in the form of streams for viewing. Compared with the traditional way of downloading and playing multimedia files, the biggest advantage of streaming media is that users only need to download the first part of the data to the local buffer to play, and download while broadcasting, so as to realize continuous playback. This streaming transmission method not only greatly shortens the start-up delay of program playback, but also greatly reduces the demand for the user's local buffer space. [0003] However, since the Internet provides best-effort services, it cannot provide QoS (Quality of Service) gua...
