【摘要】：随着近年来互联网的迅速发展,信息时代的到来,作为三网融合下的产物,IPTV已经成为家电领域产业发展的一个重要方向。IPTV集宽带互联网、多媒体等多种技术于一体,向用户呈现出来的各项业务越来越丰富多彩。同时在云计算、大数据的时代所产生的WebOS,其与IPTV的结合也将带来更多的技术创新。浏览器作为IPTV中用户使用其许多业务的重要应用软件,它更多的是相当于一个平台而非仅仅只是一个软件。因此,根据用户需求来设计出一个高性能的、功能丰富的、体验效果好的浏览器将变的尤为重要。本文首先分析了常见浏览器与WebOS的相关技术特点,研究了开源浏览器内核WebKit的架构及其相关技术;通过分析SDL与其他GUI系统的优缺点,提出了适用于中低端设备、多功能的浏览器解决方案。其次,通过对WebKit的PlatForm模块进行优化,设计了一个基于SDL平台的中间件模块,使机顶盒中的浏览器具有高效的外部事件处理和显示能力,为IPTV的视频点播提供了快进、快退、暂停等相关业务接口,以及控制屏幕上焦点框快速且正确的移动到目标结点的相关接口。最后,设计实现了一个具有IPTV人机交互功能的浏览器原型,对所研究方案和中间件进行了验证。结果表明,该浏览器能够正确并高效的处理遥控器事件以及进行IPTV视频点播业务。
[Abstract]:With the rapid development of the Internet in recent years and the arrival of the information age, IPTV, as a product of the integration of three networks, has become an important direction of industrial development in the field of home appliances. IPTV integrates broadband Internet, multimedia and other technologies. The various services presented to the users are becoming more and more colorful. At the same time, the combination of big data and cloud computing will bring more technological innovation. As an important application software for users to use many of their services in IPTV, browser is more like a platform than just a software. Therefore, it is very important to design a browser with high performance, rich function and good experience effect according to the needs of users. In this paper, the characteristics of common browsers and WebOS are analyzed, the architecture of open source browser kernel WebKit and its related technologies are studied, and the advantages and disadvantages of SDL and other GUI systems are analyzed. Multifunctional browser solution. Secondly, through the optimization of platform form module of WebKit, a middleware module based on SDL platform is designed, which makes the browser in the set-top box have efficient external event handling and display ability, and provides fast forward and fast retreat for IPTV VOD. Pauses and other related business interfaces, as well as the control screen focus box quickly and correctly moved to the target node related interfaces. Finally, a browser prototype with IPTV human-computer interaction is designed and implemented, and the research scheme and middleware are verified. The results show that the browser can handle remote control events correctly and efficiently and perform IPTV VOD service.
