【摘要】： 隨著互聯(lián)網(wǎng)的發(fā)展,傳統(tǒng)多媒體技術(shù)已漸漸難以滿足用戶日益增長的需求。而增加了豐富交互性的富媒體的出現(xiàn),為傳統(tǒng)互聯(lián)網(wǎng)廣告帶來了革命性的變化。同時,隨著移動多媒體業(yè)務(wù)的發(fā)展,富媒體也將在移動平臺上有越來越廣闊的應(yīng)用前景。 本文闡述了富媒體系統(tǒng)所具有的基本架構(gòu),以及富媒體技術(shù)所關(guān)注的關(guān)鍵技術(shù)。在分析和比較了當(dāng)前較為流行的幾種與富媒體有關(guān)的公開標(biāo)準(zhǔn)之后,采用了LASeR這一涵蓋了富媒體端到端服務(wù)的標(biāo)準(zhǔn)作為本文設(shè)計的富媒體系統(tǒng)所遵循的基本標(biāo)準(zhǔn)。本文利用開源多媒體框架GPAC,基于LASeR標(biāo)準(zhǔn)設(shè)計了富媒體系統(tǒng)的客戶端與服務(wù)器模塊。其中客戶端模塊包括了對接收的媒體流的重新排序和解析、對各種音視頻以及場景文件的播放與同步,以及對腳本交互事件的處理。服務(wù)器模塊包括業(yè)務(wù)處理模塊、場景處理模塊、場景下發(fā)模塊和媒體發(fā)送模塊等。同時實現(xiàn)了按照時間將SVG文檔分割為LASeR相應(yīng)新增\更新\插入等命令這一技術(shù)細(xì)節(jié),并在此系統(tǒng)上設(shè)計實現(xiàn)了電視投票業(yè)務(wù)。最后,本文采用了流媒體服務(wù)器端到端地驗證了該系統(tǒng)的正確性,且能夠看到電視投票業(yè)務(wù)在該系統(tǒng)上運行狀況良好。
[Abstract]:With the development of Internet, traditional multimedia technology has been difficult to meet the increasing needs of users. The emergence of rich media with rich interactivity has brought revolutionary changes to traditional Internet advertising. At the same time, with the development of mobile multimedia service, rich media will have more and more broad application prospects on mobile platform. This paper describes the basic structure of rich media system and the key technology of rich media technology. After analyzing and comparing several popular open standards related to rich media, LASeR, which covers the end-to-end service of rich media, is adopted as the basic standard of the rich media system designed in this paper. In this paper, the client and server modules of rich media system are designed by using open source multimedia framework (GPAC) based on LASeR standard. The client module includes the reordering and parsing of received media streams, the playback and synchronization of various audio and video and scene files, and the handling of script interaction events. The server module includes service processing module, scene sending module and media sending module. At the same time, the technical details of dividing SVG documents into new\ updated\ inserted commands of LASeR according to time are realized, and the TV voting service is designed and implemented on this system. Finally, this paper uses streaming media server to verify the correctness of the system, and can see that the TV voting service works well on the system.
