【摘要】：本论文利用J2ME技术设计和实现手机终端媒体信息实时传输和储存系统。所谓J2ME，，英文全称为Java2Micro Edition，进入本世纪之后，这项技术在移动通信领域的发展十分迅猛，尤其是在电子商品方面得到了广泛应用。目前普通的电子商品很难满足消费者的需求，无论是使用手机，机顶盒，还是专用设备，消费者都有明确的期望值。甚至对于传统的独立设备，可靠性，易用性，个性化和网络感知都成为越来越重要的特性。作为支持这些设备的基本平台，Java ME完全符合要求，因为它规模小，高度可移植且功能强大。对设备的智能化、多样化提供了革命性的解决方案，并因其“Write Once, run anywhere”的Java特性而提高开发效率。本论文正是基于该项技术，专门针对手机研发了这套程序，目的是实现媒体信息实时传输以及储存。本文设计并实现了四个模块：媒体资源获取模块，媒体资源编辑模块，媒体资源上传模块，媒体资源存储模块。系统在媒体信息上传过程中，改进LZW算法对媒体信息进行压缩，提高了压缩率，减少带宽和流量，提高网络传输率。在媒体信息实时传输中，设计并实现了能自动调节“心跳时间”的心跳包，能够及时检测网络的连接状态，保证数据传输的实时性和有效性。本系统已经在实习公司内部投入使用，本论文的研究成果在用户对移动终端大批量信息数据的网络存储，以及图片，音频，视频等媒体资源分享的迫切需求中具有重要的实际应用价值。
[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.
