Embodiment Construction

[0025] In order to make the above-mentioned features of the present invention more obvious and understandable, the preferred embodiments are specifically cited below in conjunction with the schematic diagrams, and are described in detail:

[0026] figure 1 It is a general architecture diagram of multiple media format stream output, figure 2 It is a diagram of the overall structure of multiple media format streaming in the present invention, image 3 and Figure 4 It is a schematic diagram of multiple media format stream output in the present invention. Client 1 initiates an http request to web server 2 to obtain the required multimedia files; web server 2 will determine whether the file required by client 1 exists locally after receiving the request, and if so, web server 2 will go to the cache system 3 Find out if the file is cached. If the cache system 3 has the file, it will directly return the data to the web server 2, and the web server 2 will return the data to the c...

Abstract

The invention provides a device and a method for outputting multi-media format flows. The device at least comprises a Web server, a distributed cache system and a transcoding server cluster, wherein the Web server is used for receiving a HTTP (Hyper Text Transport Protocol) request, and sending the content of the request to the cache system or the transcoding server cluster; the distributed cache system is used for accessing data and returning the data to the Web server or receiving real-time data flows from the transcoding server cluster; the transcoding server cluster is used for sending transcoded data to the cache system and informing the Web server to access the data. The invention provides clients with multi-media format files in the way of real-time transcoding and caching, and has the advantages of greatly reducing redundancy backup and repeated storage of the data and avoiding unnecessary loss of the multi-media data so as to improve the serviceability of the system, simplify the processing procedures of the system and reduce complexity of design and implementation of the system.

Description

technical field [0001] The invention belongs to the field of video communication, and in particular relates to a device and method capable of realizing stream output in multiple media formats. Background technique [0002] Multimedia technology is a technology that can process information on multiple carriers (media) and information on multiple storage bodies (media). It is a computer interactive and comprehensive processing of multimedia information - text, graphics, images and sounds, so that multiple information can be logically connected, that is, a technology that becomes a system and is interactive. [0003] The invention mainly relates to the application of multimedia technology in the field of computer communication. Multimedia is the combination of computer and video technology that presents information, communicates ideas and expresses emotions, allowing you to see, hear and understand the thoughts of others. In other words, multimedia technology is a form of com...
