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.
