【摘要】：隨著計(jì)算機(jī)、通信技術(shù)的革命性進(jìn)步和發(fā)展,手機(jī)不僅僅用來傳遞語音,而且可以傳遞文字短信、多媒體彩信、圖書、廣告等內(nèi)容,在目前的技術(shù)水平下,流暢的視頻傳輸也成為了現(xiàn)實(shí),使手機(jī)這一通信工具開始媒體化。這一的背景下,手機(jī)電視這一新興事物應(yīng)運(yùn)而生,手機(jī)的移動(dòng)性、便攜性、互動(dòng)性與具有豐富內(nèi)容的電視內(nèi)容相結(jié)合,將信息和娛樂功能的應(yīng)用提升到了新的高度。 從業(yè)務(wù)形態(tài)上看,手機(jī)電視業(yè)務(wù)分為點(diǎn)播、直播、下載三種,從實(shí)現(xiàn)方式上看,可分為單播方式(可視通話方式、流媒體方式)和廣播方式(MBMS、CMMB),由于MBMS缺少終端支撐,CMMB由廣電主導(dǎo),內(nèi)容數(shù)量偏少,且缺少上行鏈路支持,目前的手機(jī)電視業(yè)務(wù)平臺(tái)是基于單播方式設(shè)計(jì)建設(shè)的。 為了提高用戶體驗(yàn),后期計(jì)劃設(shè)計(jì)建設(shè)內(nèi)容檢索與推薦系統(tǒng),向用戶個(gè)性化的推薦用戶可能喜歡的內(nèi)容。 本文將從系統(tǒng)架構(gòu)、相關(guān)協(xié)議、功能實(shí)現(xiàn)、內(nèi)容檢索與推薦等多個(gè)方面詳細(xì)介紹基于單播的手機(jī)電視業(yè)務(wù)平臺(tái)工作原理。
[Abstract]:With the revolutionary progress and development of computer and communication technology, mobile phones are used not only to transmit voice, but also to transmit text messages, multimedia MMS, books, advertisements, and so on. Smooth video transmission has also become a reality, so that the mobile phone as a communication tool began to media. Under this background, mobile TV, as a new thing, emerges as the times require. Mobile phone mobility, portability, interactivity and rich content of TV content are combined to promote the application of information and entertainment to a new height. From the view of service form, mobile TV service can be divided into three types: on demand, live broadcast and download, and can be divided into unicast mode (visual call mode). Streaming media mode) and broadcast mode (MBMS / CMMB). Due to the lack of terminal support, MBMS is dominated by radio and television, the quantity of content is less, and the uplink support is not enough. The current mobile TV service platform is designed and constructed based on unicast mode. In order to improve the user experience, a content retrieval and recommendation system is designed and constructed in the later stage, and the content that the user may like is recommended to the user individualized. In this paper, the operating principle of mobile TV platform based on unicast is introduced in detail from several aspects, such as system architecture, related protocols, functional implementation, content retrieval and recommendation.
