The Software Integrated Multimedia & Data Communication And Video Processing Optimization

With demand for communication and Internet technology fast increasing, multimedia communication technology has been in its rapid development. The real-time multimedia communications is one of the most prominent directions. To meet these needs, this paper has developed a real-time multimedia terminal.The main work of this article is to implement a multimedia conference system terminal software. First, through investigation and analysis of multimedia communications software, we identified the soft terminal functions and related technologies, according to which we achieved real-time communication of multimedia features. In this article, SIP protocol is used for multimedia communications session initiation and Java media processing framework for real-time multimedia processing. Under the management by the JMF framework, multimedia data are captured from the video and audio devices, compressed by H.264 codec, packaged into RTP packet, and finally sent to the destination through network. When the client receives the multimedia data, the software will decode and display them to users. To assist audio and video communications, we also define the text module to expand multimedia conferencing system. The flexible text communication module can work in parallel with the audio and video module..There are many points needed to be optimized in the video processing of JMF. For example, to implement high compression H264 codec, and to control bit rate according the network conditions. We can optimize the media processing in sending and receiving stages to improve the multimedia data transfer rate.
