Universal multimedia player frame

Abstract

The invention provides a universal multimedia player frame, which comprises a player module, a multimedia type identifier, a media file analyzer, an audio and video decoder and an audio and video synchronous output module which are connected in sequence; the multimedia type identifier and the media file analyzer are connected with a player data operating interface module; the player data operating interface module is carried with a universal file type identifier; the media file analyzer is carried with a universal file analyzer; and the audio and video decoder is carried with a universal audio and video decoder. In the invention, a suit of universal interfaces can be expanded on different types of media players so that the developer is convenient to realize expanding function to the player under the precondition of without caring about the type of the media frame, which is particularly easy to realize the function of protecting multimedia digital edition.

Description

【Technical field】 [0001] The invention relates to the field of a multimedia player framework on an embedded development platform. 【Background technique】 [0002] With the common development of Internet technology and digital technology, more digital (audio and video) works have been placed in the open environment of the Internet, and digital works have also been widely disseminated and applied due to the development of network technology. Many people can share information, but too many people ignore how many people's interests will be damaged from the generation of digital works to the dissemination of them. In recent years, the legal use of digital works, copyright ownership, and legitimate income issues have plagued content providers, disseminator, and users of digital works from different fields, and many people can freely and freely use the original version of digital works Editing, modifying, copying and distributing, so the issue of copyright protection of digital wor...

Problems solved by technology

[0007] The first kind of multimedia player provided by the development platform of the international large company mentioned above, because their respective platforms have their own set of media process standards, so the technology in digital copyright protection also has its own set of standards, and this set The standard is closely connected with the player. If product developers want to implement playback technology on their platform and at the same time protect their own copyrights, they can only use the digital copyright protection technology on the development platform, which requires Product developers have to re-implement their own copyright protection technology. In this way, product developers not only increase the development cost, but also lengthen the development cycle

[0008] The second type of embedded platform provided by domestic manufacturers, generally, multimedia players use currently known open source player frameworks, such as FFMPEG, opencore, or their own players developed based on currently commonly used player framework processes. Generally speaking, the embedded platform has strong scalability and can achieve the purpose of manufacturer transplantation. However, since it is not a player developed by itself, it will definitely take a lot of time and manpower to implement the player on the code transplantation and architecture process layer. The purpose of transplantation, in this case, the development cycle is subject to the type of multimedia player provided by the platform manufacturer, which seriously affects the time to market of the product

[0009] The last mentioned development platform, because it is a general-purpose platform, does not support many media types in the multimedia playback framework and software development kit. Product developers can easily implement their own encryption and decryption technology, but it is limited by playback. There are not many media types supported by the framework. If you want to increase the media type yourself, it will undoubtedly increase more and more human cost investment and prolong the development cycle.
