Embodiment 1

[0048] Such as figure 1 As shown, it is a method for video playback freeze switching described in Embodiment 1 of the present application, the method includes:

[0049] Step 101, when the video file freezes in the terminal, obtain the download code stream value of the video file, wherein the download code stream value is the code stream value during the process of downloading the video file from the server.

[0050]In step 101, the video file is stored in the server, which may be a corresponding video server or a database dedicated to storing videos. Of course, the stored video has been transcoded and converted into a suitable format. The format of transmission and playback (including a variety of stream formats), in this embodiment, the server can adopt a cloud architecture, wherein the video server can be used as a cloud storage server for video storage, that is, users everywhere or transfer The code server can upload the video resources suitable for transmission and playba...

Embodiment 2

[0061] Such as figure 2 As shown, it is a method for video playback freeze switching described in Embodiment 2 of the present application, the method includes:

[0062] Step 201, when the video file freezes in the terminal, obtain the download code stream value of the video file, wherein the download code stream value is the code stream value during the process of downloading the video file from the server.

[0063] It should be noted that when the video is transmitted over the network (such as when downloading or uploading), the entire video file is not transmitted in a coordinated manner, but the video files are transmitted in a certain order to form a data sequence, that is, to form a data stream. way to transmit. Then, the client can obtain the download stream value corresponding to the video file by monitoring the amount of data transmitted per unit time during the downloading process of the video. Of course, the client may acquire the code stream value corresponding t...

Embodiment 3

[0082] The specific application of the method for video playback freeze switching is described in detail below:

[0083] Setting: the client in this embodiment is a multi-functional Internet TV, and the user uses the Internet TV to watch videos during the peak period of the Internet (the state of the network bandwidth at this time is relatively poor), and the level of the code stream value is determined by Small to large can be: 350, 800, 1000, 1300, 720P, and 1080P. The Internet TV currently downloads ultra-high-definition video A (the corresponding download stream value is 1080P) from the server for playback.

[0084] The process of video playback freeze switching (that is, the adjustment in the above technical solution) is as follows:

[0085] Step 1: Video A freezes during playback on the IPTV. At this time, the IPTV obtains the download stream value corresponding to the video A, that is, the acquired download stream value of Video A is 1080P.

[0086] Step 2: The IPTV di...

Abstract

The invention discloses a video playing unsmoothness switching method and system. The method comprises, when playing unsmoothness of a video file occurs on a terminal, obtaining the downloading code stream value of the video file, wherein the downloading code stream value is the code stream value of the video file during the downloading process from a server; instructing the server side to adjust the downloading code stream value of the video file step by step to be smaller than the obtained downloading code stream value of the video file; downloading the video file according to the adjusted downloading code stream value and meanwhile determining whether the playing unsmoothness of the video file on the terminal is eliminated; if so, instructing the server side to stop the step-by-step adjustment and downloading the video file according to the downloading code stream value corresponding the elimination of the playing unsmoothness. The video playing unsmoothness switching method and system can achieve downloading code stream switching when the playing unsmoothness occurs, thereby solving the problem of playing unsmoothness of videos due to code streams of the videos.

Description

technical field [0001] The present application relates to the field of video transcoding, and more specifically, to a method and system for video playback freeze switching. Background technique [0002] With the rapid development of information technology, the form of expression and transmission of information has changed: from traditional text (such as: books, newspapers) and audio (such as: broadcasting) to more vivid and expressive Informative video way. Today's TV and the Internet present and share rich and comprehensive resources such as various film and television programs, news, advertisements, chats, education, and games in the form of video, so that video has become an irreplaceable and important tool for people to learn, socialize, and entertain. Way. [0003] At present, video websites convert rich video resources into various streams suitable for playback after transcoding. The code stream is also called the code rate, which refers to the data flow used by the...
