【摘要】：近年來,隨著我國經(jīng)濟以及通信業(yè)務(wù)的快速發(fā)展,第三代移動通信網(wǎng)絡(luò)被廣泛的應(yīng)用在人們的日常生活中；同時,嵌入式技術(shù)以其低成本、低功耗、小體積、高穩(wěn)定性和內(nèi)核可裁剪性等特點,廣泛的進入了通訊、網(wǎng)絡(luò)、工控、醫(yī)療、電子等行業(yè)中；而多媒體做為傳遞文字、聲音、圖像和圖形等信息的載體,早已成為了人們?nèi)粘Ｉ钪械囊徊糠帧?本文的研究課題就是把以上三個方面的內(nèi)容結(jié)合起來：3G網(wǎng)絡(luò)、嵌入式系統(tǒng)和多媒體。在3G無線網(wǎng)絡(luò)環(huán)境下,嵌入式設(shè)備上,實現(xiàn)了多媒體的編碼采集、網(wǎng)絡(luò)傳輸以及解碼播放,并在此基礎(chǔ)上實現(xiàn)了3G嵌入式圖像傳輸系統(tǒng)。 3G嵌入式圖像傳輸系統(tǒng)采用OMAP3530處理器,在功能上實現(xiàn)了CDMA2000無線上網(wǎng)、在線實時播放、線下本地播放、自動下載本地文件等功能。服務(wù)器能控制客戶機在什么時候播放什么內(nèi)容,從而解決了市場上現(xiàn)有的流媒體播放設(shè)備更新播放內(nèi)容困難以及各個客戶機之間播放不同步等問題。項目開發(fā)經(jīng)過了前期的選題、市場調(diào)研、技術(shù)分析等階段,現(xiàn)在已經(jīng)進入試驗階段且運行測試效果良好。
[Abstract]:In recent years, with the rapid development of economy and communication services in our country, the third generation mobile communication network has been widely used in people's daily life, at the same time, embedded technology with its low cost, low power consumption, small volume, Features such as high stability and tailoring of the kernel are widely used in the fields of communication, network, industrial control, medical treatment, electronics and so on, while multimedia is used as the carrier of information such as text, sound, image and graphics, etc. It has long been a part of people's daily lives. The research topic of this paper is to combine the above three aspects together: 3G network, embedded system and multimedia. In the 3G wireless network environment, the multimedia coding collection is realized on the embedded equipment. On the basis of network transmission and decoding and playing, a 3G embedded image transmission system is implemented. The 3G embedded image transmission system uses OMAP3530 processor to realize the functions of CDMA2000 wireless internet access, online real-time playback, offline local playback, automatic downloading of local files, etc. The server can control when and when the client plays what content. In order to solve the problems such as the difficulty of updating and playing content of the existing streaming media playback equipment in the market and the non-synchronization of the playback among the various clients, the project development has gone through the earlier stage of selected topics, market research, technical analysis, and so on. Now it has entered the experimental stage and runs the test well.
