Abstract: Through the analysis of MPEG-4 video coding essential technology and principles,a video-medical system was developed,based on JMF and applied in the intellectualized community by using real-time,highly effective wireless video transmission features of MPEG-4.In video service system,JMF provides a unified construction and correspondence agreement to manage the gain,processing and the transmission of the time-based media.The adoption of real-time transmission agreement/Real-time transmission controlling agreement(RTP/RTCP) guarantees the video transmission process timeliness well,and introduces MPEG-4 compression algorithm plug-in unit in JMF to ensure the video compression.The compression rate of MPEG-4 compression algorithm is relatively higher and has strong network compatibility,which produces good effect in the procedure realization process.

摘要: 通过对MPEG-4视频编码关键技术及原理的分析,利用MPEG-4视频技术实时、高效无线视频传输的特性,开发、设计并实现了基于JMF技术、应用于智能化社区的视频医疗系统。在视频医疗系统中,由JMF提供一个统一的架构和通信协议来管理基于时间媒体的获取、处理和传输。采用实时传输协议/实时传输控制协议(RTP/RTCP)很好的保证了视频传输过程中的实时性,并在JMF中引入了MPEG-4压缩算法插件进行视频压缩。MPEG-4压缩算法压缩比高,并且具有良好的网络适应性。
