In recent years, with the increase of the wireless business, people are more and more interested in videophone, and wireless video communication becomes the new demand of the wireless communication.(近年來，隨著無線業(yè)務(wù)的增加，人們對(duì)可視電話等視頻業(yè)務(wù)越來越感興趣，無線視頻通信成為無線通信的新需求。)

Your wristwatch videophone suddenly rings.(突然，你手表上的可視電話響了。)

The videophone, which combinewiths the computer's alternation, the communication's distribution, and the multimedia's real-time characteristic, is accepted by more information and timely responds.(可視電話系統(tǒng)正是以這種信息多元化、響應(yīng)及時(shí)化等特點(diǎn)頗受大眾接受，它將計(jì)算機(jī)的交互性、通信的分布性和多媒體的實(shí)時(shí)性完美的結(jié)合起來。)

The invention solves the problems that the creating process ofthe videophone session has more links, and the switching-on consumed time is longer.(解決了可視電話會(huì)話建立流程環(huán)節(jié)較多，接通耗時(shí)比較長的問題。)

TECHNOLOGICAL prophets have forecast the triumph of video calling ever since 1936, when Germany's Reichspost launched the first public videophone service.(早在1936年，當(dāng)?shù)聡蹏]政首次推出公共視頻電話服務(wù)時(shí)，科技預(yù)言家就預(yù)言可視電話將會(huì)取得巨大成功。)

The invention also discloses method for writing information on videophone.(本發(fā)明還公開了一種在可視電話上書寫信息的方法。)

The videophone includes following parts: video encoding and decoding units;(本發(fā)明公開了一種可視電話，包括視頻編解碼單元；)

IntroductionIn the communication systems, echo and noise will seriously affect speech communication quality, such as IP telephone, videophone and hand-free digital cell phone systems etc.(引言在通信系統(tǒng)中，例如IP電話、可視電話及免提數(shù)字蜂窩電話系統(tǒng)中，回聲和噪聲會(huì)嚴(yán)重影響通信質(zhì)量。)

In 2003, the Company launched its first consumer videophone services on the Packet8 network.(2003年，公司推出了其第一消費(fèi)者可視電話服務(wù)的利用Packet8網(wǎng)絡(luò)。)

The videophone software system is devided into two parts. One is the graphic frame and the other is the application module.(嵌入式可視電話的軟件系統(tǒng)主要分成兩部分，即圖形框架和應(yīng)用組件。)
