【摘要】：本論文利用J2ME技術(shù)設(shè)計(jì)和實(shí)現(xiàn)手機(jī)終端媒體信息實(shí)時(shí)傳輸和儲(chǔ)存系統(tǒng)。所謂J2ME，，英文全稱為Java2Micro Edition，進(jìn)入本世紀(jì)之后，這項(xiàng)技術(shù)在移動(dòng)通信領(lǐng)域的發(fā)展十分迅猛，尤其是在電子商品方面得到了廣泛應(yīng)用。目前普通的電子商品很難滿足消費(fèi)者的需求，無論是使用手機(jī)，機(jī)頂盒，還是專用設(shè)備，消費(fèi)者都有明確的期望值。甚至對(duì)于傳統(tǒng)的獨(dú)立設(shè)備，可靠性，易用性，個(gè)性化和網(wǎng)絡(luò)感知都成為越來越重要的特性。作為支持這些設(shè)備的基本平臺(tái)，Java ME完全符合要求，因?yàn)樗?guī)模小，高度可移植且功能強(qiáng)大。對(duì)設(shè)備的智能化、多樣化提供了革命性的解決方案，并因其“Write Once, run anywhere”的Java特性而提高開發(fā)效率。 本論文正是基于該項(xiàng)技術(shù)，專門針對(duì)手機(jī)研發(fā)了這套程序，目的是實(shí)現(xiàn)媒體信息實(shí)時(shí)傳輸以及儲(chǔ)存。本文設(shè)計(jì)并實(shí)現(xiàn)了四個(gè)模塊：媒體資源獲取模塊，媒體資源編輯模塊，媒體資源上傳模塊，媒體資源存儲(chǔ)模塊。系統(tǒng)在媒體信息上傳過程中，改進(jìn)LZW算法對(duì)媒體信息進(jìn)行壓縮，提高了壓縮率，減少帶寬和流量，提高網(wǎng)絡(luò)傳輸率。在媒體信息實(shí)時(shí)傳輸中，設(shè)計(jì)并實(shí)現(xiàn)了能自動(dòng)調(diào)節(jié)“心跳時(shí)間”的心跳包，能夠及時(shí)檢測(cè)網(wǎng)絡(luò)的連接狀態(tài)，保證數(shù)據(jù)傳輸?shù)膶?shí)時(shí)性和有效性。 本系統(tǒng)已經(jīng)在實(shí)習(xí)公司內(nèi)部投入使用，本論文的研究成果在用戶對(duì)移動(dòng)終端大批量信息數(shù)據(jù)的網(wǎng)絡(luò)存儲(chǔ)，以及圖片，音頻，視頻等媒體資源分享的迫切需求中具有重要的實(shí)際應(yīng)用價(jià)值。
[Abstract]:And the realization of mobile phone terminal media information real-time transmission and storage system design. This paper uses J2ME technology called J2ME, English called Java2Micro Edition, after entering the new century, the development of this technology in the field of mobile communication is very rapid, and it is especially widely used in electronic products. At present, it is difficult to meet the ordinary electronic goods the needs of the consumers, whether it is the use of mobile phone, set-top boxes, or special equipment, consumers have clear expectations. Even for the equipment, independent of traditional reliability, ease of use, personalized and network have become more and more important. As a basic platform to support these devices, Java ME fully meet the requirements for it is small, highly portable and powerful. The intelligent equipment, diversification provides a revolutionary solution, and because of its "Write Once, run anywhere Java Characteristics and improve the efficiency of development.
This thesis is based on the technology, specialized research and development of this set of procedures for the mobile phone, is to achieve the purpose of transmitting real-time media and information storage. This paper presents the design and implementation of four modules: media resource acquisition module, media resource editing module, media resources, media resources upload module, storage module. The system information in the media upload process in the improved LZW algorithm to compress the media information, improves the compression rate, reduce the bandwidth and traffic, improve the network transmission rate. In the transmission of real-time multimedia information, is designed and implemented to automatically adjust the "heartbeat time" heartbeat packet can detect network connection state, to ensure the effectiveness and real-time data transmission.
The system has been put into practice in the internship company. The research results in this paper have important practical application value in the urgent need for users to share the mass data and information of mobile terminals, and share media resources such as pictures, audio, video and so on.
