【摘要】：机顶盒中间件一般由第三方芯片厂商提供,不同芯片厂商根据集成文档定制开发中间件,API标准和特点各自不一,这对机顶盒厂商来说,每需推出新的中间件或与不同芯片厂商对接时都意味着一次重复定制研发过程,很大程度影响生产效率和规模,同时也增加了成本。所以有必要对机顶盒集成接口进行统一化规范化设计。本文针对这一需求研究一种机顶盒统一接口,基于mstar芯片平台而设计,该设计将芯片厂商所需提供的各种数字机顶盒功能进行规范化封装,以统一接口形式提供给芯片厂商,仅需简单调用便可完成相关功能研发。系统的功能和性能测试表明,该接口与现有的一些系统接口相比,具有低耦合、易集成、易扩展和易维护性,同时具备更完善的功能,更高的集成效率,更优越的稳定性和移植性。本论文基于对当前常规的数字机顶盒业务调查研究,做出其统一接口功能需求分析,得出系统各业务涉及的具体集成功能列表,随后对应的依据功能列表需求分析对系统集成功能模块划分做出系统体系结构设计,并进一步对各模块具体内容进行模块设计,具体包括:OS模块,对应操作系统功能;SOCKET模块,对应网络通信功能;FS模块,对应文件存储功能;OSD模块,对应界面绘图功能;多媒体模块,对应多媒体应用功能。接下来对系统各主要模块进行具体实现并完成系统功能和性能测试,最后得出结论并提出下一步系统完善工作。本课题采用代表性的知名晨星半导体芯片mstar,并选择三家代表性的芯片厂商:天柏集团、同洲电子以及数码视讯。系统依据较为严格的广东省、河南省及天津市广电验收标准良好通过各项测试。本课题研究设计的统一接口稳定可靠的满足中间件各项功能需求,其完善良好的功能支持在充分提升集成性能和效率的同时大大降低集成难度和成本。在公司产品推广、经济创效以及研发成本和效率等多发面都能够发挥非常实际有益的应用价值。
[Abstract]:STB middleware is generally provided by third-party chipmakers. Different chipmakers customize and develop middleware API standards and characteristics according to integration documents. Each time a new middleware is introduced or interfaced with different chipmakers, it means a repeat of the custom R & D process, which greatly affects production efficiency and scale, but also increases costs. So it is necessary to unify and standardize the STB integrated interface. In this paper, a unified STB interface is studied, which is based on mstar chip platform. The design encapsulates all kinds of digital STB functions provided by chip manufacturer and provides them to chip manufacturer in the form of unified interface. Only a simple call can complete the development of related functions. The system function and performance tests show that the interface has low coupling, easy integration, easy expansion and maintainability, better function and higher integration efficiency, compared with some existing system interfaces. Superior stability and portability. In this paper, based on the investigation and research of the current routine digital set-top box service, the unified interface function requirement analysis is made, and the specific integrated function list of the system is obtained. Then, according to the requirement analysis of the functional list, the system architecture is designed for the partition of the system integration function module, and the specific contents of each module are further designed, including the specific module of the: OS, the module of the corresponding operating system function and the module of socks. Corresponding network communication function / FS module, corresponding file storage function / OSD module, corresponding interface drawing function, multimedia module, corresponding multimedia application function. Then the main modules of the system are implemented and the system function and performance are tested. Finally, the conclusion is drawn and the further work of system improvement is put forward. This thesis adopts the famous Morningstar semiconductor chip Mstar. and selects three representative chip manufacturers: Tianbo Group, Tongzhou Electronics and Digital Video. The system passed the tests according to the strict acceptance standards of Guangdong, Henan and Tianjin. The unified interface designed in this paper meets the functional requirements of middleware stably and reliably, and its perfect and good functional support can greatly reduce the difficulty and cost of integration while fully improving the performance and efficiency of integration. In the company product promotion, economic efficiency and R & D costs and efficiency can play a very practical and useful application value.
