【摘要】： 如今,無線技術(shù)日趨成熟,3G技術(shù)、WIFI技術(shù)不斷完善并得到支持。在無線接入得到保證的基礎(chǔ)上,能給客戶帶來什么樣的信息資源,能為客戶提供什么樣的移動(dòng)增值服務(wù),是獲得客戶青睞的重要條件。以移動(dòng)電視、VOD點(diǎn)播、視頻會(huì)議等業(yè)務(wù)為主的移動(dòng)網(wǎng)絡(luò)服務(wù)比文字信息和音頻信息業(yè)務(wù)具有更直觀更多樣化的優(yōu)勢(shì)。 在國(guó)外,隨著IP多媒體子系統(tǒng)(IMS,IP Multimedia Subsystem)通信方式的技術(shù)規(guī)格在日本由多家廠商聯(lián)合通過測(cè)試并獲得成功,國(guó)外的移動(dòng)多媒體業(yè)務(wù)不斷開展。但是IMS技術(shù)對(duì)國(guó)內(nèi)廠商還比較陌生,能否被國(guó)內(nèi)市場(chǎng)所接受還有待時(shí)間和市場(chǎng)的考驗(yàn)。國(guó)內(nèi)的移動(dòng)多媒體研究也不甘落后,2005年廣電總局確定了“天地一體”的移動(dòng)多媒體廣播(CMMB,China Mobile Multimedia Broadcasting)技術(shù)體制和方案。但是這套方案依賴于衛(wèi)星轉(zhuǎn)播和地面大型基站的建設(shè),而且客戶端必須加裝特定的模塊才能支持。要發(fā)展起來也需要時(shí)間和市場(chǎng)的考驗(yàn)。 然而,隨著WIFI無線信號(hào)的鋪開,通過WIFI進(jìn)行無線接入的模式已經(jīng)非常普及。同時(shí),目前流行的Symbian、Windows Mobile、Android等智能手機(jī)操作系統(tǒng)都能夠很好地支持各種編碼方式的多媒體應(yīng)用。本論文就是在這樣的背景下,基于已經(jīng)相當(dāng)成熟的WIFI接入技術(shù),針對(duì)智能手機(jī)終端設(shè)計(jì)一套WIFI廣播系統(tǒng),研究如何讓智能手機(jī)終端通過WIFI連接接收視頻信息,并可擴(kuò)展視頻點(diǎn)播、廣告推送等多業(yè)務(wù)平臺(tái),提出利用WIFI網(wǎng)絡(luò)對(duì)視頻信息進(jìn)行組播的方式,解決在視頻播放不順暢的情況下如何進(jìn)行補(bǔ)償,保證手機(jī)終端收看視頻的順暢。
[Abstract]:Today , wireless technology is becoming mature , 3G technology and Wi - Fi technology are continuously improved and supported . On the basis of wireless access , what kind of information resources can be brought to customers and what kind of mobile value - added service can be provided to customers is the important condition that customers favor . Mobile network services such as mobile TV , VOD on demand and video conference have more visual and more diversified advantages than text information and audio information service .



In foreign countries , as IP Multimedia Subsystem ( IP Multimedia Subsystem ) communication mode has been successfully tested and successful by several manufacturers , mobile multimedia service abroad has been continuously carried out . However , IMS technology is still unknown to domestic manufacturers , and can be accepted by domestic market for time and market . However , the scheme relies on the construction of satellite relay and ground large base station , and the client must install specific module to support . It also needs time and market test .



However , with the spreading of the wireless signal , the mode of wireless access is very popular through Wi - Fi . At the same time , it is very popular for smart phone operating systems such as symbian , Windows Mobile and Android to support multimedia applications in all kinds of coding modes . In this background , based on the quite mature Wi - Fi access technology , this paper researches how to make the smartphone terminal receive video information through the Wi - Fi connection , and to expand the multi - service platform such as video on demand and advertisement push .
