Problems solved by technology

[0003] When playing a video, the corresponding video data can be sent to the user's terminal device for playback according to the resolution selected by the user, so that the video server will store decoded video data of different resolutions in order to provide users with different resolutions video viewing experience, but this will inevitably take up a lot of storage space and storage devices

Embodiment Construction

[0052] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0053] Such as figure 1 As shown, an embodiment of the video playback method provided by the present invention, the video playback method includes:

[0054] In step 101, a virtual slice is performed on a video source.

[0055] Step 102, receiving a video play request, where the play request includes the play time node, definition and play format.

[0056] Step 103, check whether there is a video slice corresponding to the playback request in the content distribution network.

[0057] Step 104, if it exists, directly send the corresponding video slice to the playback terminal.

[0058] Step 105, otherwise, search for the first virtual slice corresponding to the time node of the playing request.

[0059] Step 106: Carry...

Abstract

The invention discloses a video playing method and system. The method comprises the steps that a virtual slice module conducts virtual slicing on a video source; a request receiving module receives a video playing request, wherein the video playing request contains a playing time node, definition and a playing format; a slice search module searches a content distribution network for a video slice corresponding to the playing request; if the video slice corresponding to the playing request exists, a video slice sending module directly sends the corresponding video slice to a playing terminal; otherwise, a virtual search module searches for a first virtual slice corresponding to the time node in the playing request; a slice processing module conducts slicing on the first virtual slice, and a video slice corresponding to the definition and the playing format in the playing request is obtained and sent to the playing terminal. According to the video playing method and system, a virtual slicing mode is adopted, a video is transcoded or decoded in a real-time online slicing mode, and occupation of storage space of a video server is reduced.

Description

technical field [0001] The present invention relates to the field of multimedia playing, in particular to a video playing method and system. Background technique [0002] A video website is an online media that allows Internet users to smoothly publish, browse and share video works online with the support of a complete technical platform. After the video resources are acquired, they are often data in video formats such as wmv, avi, etc. After acquiring the video resources, the video website needs to use a video transcoding tool to convert the video format into H.264 format, and then convert it into the user's Commonly used video formats in clients or terminal devices, such as MP4 format; at the same time, in order to meet the viewing experience of different users, the same video resource can be set to a variety of different resolutions, such as smooth, standard definition, high definition and ultra-high definition. During format conversion, the video resource needs to be tr...
