[0002] With the rapid development of radio and television networks, telephone networks, and the Internet, the concept of triple play has attracted more and more attention from academia and industry, and smart set-top boxes have been widely used. Smart set-top boxes refer to devices equipped with an Android system. Set-top boxes, in addition to traditional TV box functions, smart set-top boxes can realize all functions on the computer: browsing the web, watching movies, watching TV, listening to music, chatting on QQ, playing games, etc. The most important function inside the smart set-top box is to play multimedia , and the development process of media applications will encounter many challenges: 1) The amount of multimedia data is large, and the development of media applications must ensure the efficiency of data processing in order to successfully play media data; 2) The audio and video in media data must be guaranteed Time synchronization; 3) It must be able to handle multiple formats of media formats, such as AVI, MPEG, MOV, etc.; 4) It must take into account new hardware and media formats that may appear in the system in the future

The invention discloses a multimedia frame of an intelligent set top box and a method for establishing a multimedia player. According to the multimedia frame, functional modules are abstracted as a source filter, a transmission filter and a delivery filter according to differences of inputting, transmitting and outputting functions of the modules. Filter assemblies are used for producing, processing and displaying data. A pin assembly is used for connecting the adjacent filter assemblies and transmitting data. An image assembly is used for managing the filter assemblies, establishing images and interacting with applications. The development procedure of the multimedia application can be standardized. Technological guidance is provided for module dividing, data transmitting and function switching of the multimedia application development, and the modules have the characteristic of high cohering, low coupling and the efficient code reusability and extendibility, is suitable for all intelligent set top boxes, capable of efficiently processing multimedia data and supporting more multimedia formats and high in practicability and extendibility and has good application prospects, and the modules can be increased according to different function demands.
