【摘要】 下一代网络(NGN)是一个建立在IP技术基础上的新型公共电信网络,能够容纳各种形式的信息,在统一的管理平台下,实现音频、视频、数据信号的传输和管理,提供各种宽带应用和传统电信业务,是一个真正实现宽带窄带一体化、有线无线一体化、有源无源一体化、传输接入一体化的综合业务网络。3Tnet网络作为下一代网络(NGN),是计算机互联网、传统的电话网和有线电视网络三网的融合。中国科学院声学所数字信号处理中心承担了国家863计划-宽带信息网运营支撑环境。其中,研制的宽带多媒体网关为3Tnet网络提供了智能终端。本文介绍了宽带多媒体网关中嵌入式浏览器的研制工作。主要完成的工作包括:根据宽带多媒体网关对浏览器的要求选择浏览器的内核,设计浏览器的整体软件框架,实现浏览器上层应用程序以及下层与平台相关的图形、网络、文件等模块的接口,设计与实现用户图形界面,设计与实现多媒体终端的人机交互,定义和实现宽带多媒体网关中浏览器与其它模块间的消息通讯等。论文的主要内容组织如下:首先,介绍了宽带多媒体网关的背景及相关技术;然后,给出了嵌入式浏览器的发展、特点、结构及相关的协议和标准;再次,介绍了与系统平台相关的硬件平台、操作系统、开发调试过程和用户图形界面Microwindows;下一步,详细给出了嵌入式浏览器在宽带多媒体网关中的实现方案,包括嵌入式浏览器在宽带多媒体网关中的位置、浏览器内核的选择、软件体系结构、各接口层的实现、与其它模块的通讯协议,并在最后给出了嵌入式浏览器的特点;最后,对所做的工作进行总结,对未来的工作进行设想。目前嵌入式浏览器已在宽带多媒体网关中实现,它既是一个网络信息浏览器,又是一个为宽带多媒体网关定制的浏览器,在宽带多媒体网关中起承上启下的作用。更多还原

【Abstract】 Next Generation Network is a new kind of network over IP, which canhold all kinds of information. In the uniform plat, NGN implements thetransmission and management of digital signals, video and audio, and alsoNGN supports broadband application and traditional telecom operation .NGNis a integrative platform for wire and wireless, broadband and narrowband,transmission and accessing.As NGN, 3TNet is the amalgamation of computer network, communityantenna television and the traditional telecom. DSP Research CenterChinese Academy of Sciences carries on the 863 project of development ofbroadband accessing and integration. Among the project, the BroadbandMultimedia Intelligent Gateway (BMG) developped turns into the necessaryuser equipments of 3TNet.This paper focuses on the development of embedded browser in BMG. Themain work includes the selection of the browser kernel, the design of thearchitecture of the browser, the implementation of the browserapplication and all the related API such as network, file, drawing, thedesign and implementation of UI and human-machine interacting, thedefinition and implementation of message communications between thebrowser and other modules in or out the BMG.The paper is organized with the following framework. Firstly, thebackground and the related technologies of BMG are introduced. Secondly,the knowledge about embedded browser, such as the evolution, features,the structure, related protocols and standards, is given. Thirdly, theplatform of BMG is described. Fourthly, the implementation of embeddedbrowser in BMG is detailed. Last, all the work is summarized and somesuggestions about the future work are given. Now embedded browser has been implemented in BMG.It is not only anetwork browser but also a customized browser for BMG, acting as theconnecting link between the preceding and the following.更多还原
