The Design And Implementation Of Videophone With Android4.0OS In CS Domain

Videophone is a very important application after human beings entered the era of3G. We can communicate with each other in a face-to-face style using videophone. Inthis way, we can not only hear the voice, but also see the image of each other. As thedevelopment direction of personal communication, smart phones are an importantplatform of videophone application. Since android4.0was published, we still cannotfind a smart phone which has realized the videophone with android4.0Operate System(OS) in Circuit Switched (CS) domain.This article makes a research on the design and implementation of videophonewith android4.0OS in CS domain in view of the fact that there is no such application.Firstly, this article elaborates the basic concepts, principles and related methods aboutvideophones. Secondly, it introduces the current realizations of videophones. Thirdly,it makes a requirement analysis of the videophone with android4.0OS in CS domain.Fourthly, it designs a method by which we can realize the application. Fifthly, itrealizes the application. Finally it tests the application and analyzes the experimentalresults.This paper involves in the key technology which realizes a videophoneapplication with android4.0OS in CS domain. It provides technical support to extendthe videophone, and fills the blank that there is no smart phone realized this application.
