Embodiment Construction

[0036] The technical solution of the present invention will be described below in conjunction with the accompanying drawings.

[0037] Such as figure 1 As shown, the embodiment of the present invention provides a video slice transmission method, which may include the following steps:

[0038] S101. The first server receives a video slice acquisition request sent by a terminal;

[0039] The first server receives the video slice acquisition request sent by the terminal. In one embodiment, the request for obtaining video slices may be a URL (Uniform Resource Locator, Uniform Resource Locator), and parsing the URL can obtain information such as slice numbers and slice formats. The target slice format can be HLS (HTTP Live Streaming, HTTP live data stream), HDS (HTTP Dynamic Streaming, HTTP dynamic data stream), MPEG (Moving Picture Experts Group, Dynamic Picture Experts Group)-DASH (Dynamic Adaptive Stream over HTTP, based on HTTP dynamic adaptive stream) and other formats.

Abstract

The invention relates to a video slice transmission method, device and system. The method comprises the following steps: a first server receives a video slice acquisition request sent by a terminal; the first server requests a virtual slice information file corresponding to a video slice and a video clip in an original video file from a second server based on the acquisition request in a back-to-source way; the second server sends the pre-generated virtual slice information file and the corresponding video clip in the original video file to the first server; the first server performs the sliceprocessing on the video clip according to the information in the virtual slice information file; and the first server returns the generated video slice to the terminal. In the video transmission process, the slice storage of the original video is unnecessary, and it is unnecessary to store the original video as multiple pieces of video data when multiple slice formats are existent, the first server is unnecessary to transmit multiple pieces of video data from the second server and unnecessary to cache multiple pieces of video data; the transmission bandwidth, the disk space and the cache space are saved.

Description

technical field [0001] The present invention relates to the technical field of streaming media live broadcast on demand, in particular to a video slice transmission method, device and system. Background technique [0002] With the development of Internet multimedia technology and the continuous increase of network bandwidth, online video has attracted a large number of users with its convenient access experience, diversified video sources, and real-time update speed, making online video an indispensable part of users' online life. essential component that is missing. [0003] Compared with the traditional frame-by-frame transmission method of streaming media live streaming, major video sites on the Internet now adopt a sliced ​​transmission protocol, which can be well implemented in HTTP (HyperText Transfer Protocol, hypertext transfer protocol), various Web (World Wide Web, Global Wide Area Network) cache and CDN (ContentDelivery Network, Content Distribution Network); how...
