The Design And Realization Of Embedded Browser In Broadband Multimedia Gateway

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.
