A remote video monitoring system based on Java Media Framework (JMF) is put forward in this paper. It is of cross-platform,
lower time-delay and lower bandwidth. The system is consisted of three layers that are data acquisition layer,
service layer and client layer. The hardware of system is connected with local area network and various video devices
can be identified in the system. The software based on Java and JMF is programmed to capture, compress, send, receive
and play video data and can be run on different operating system without modification. H.263 compression algorithm is
adopted and RTP protocol is used to transport video data with RTCP protocol in the system. The client layer can access
to the system by Internet or 3G and has convenient and flexible features. Maintenance personnel can easily supervise the
device status at any time so that the equipments are always in good condition. It is helpful to enhance the competitive
power of power plants.
The article put forward a method which had been used for video image acquisition and processing, and a system
based on Java media framework (JMF) had been implemented by it. The method could be achieved not only by B/S
mode but also by C/S mode taking advantage of the predominance of the Java language. Some key issues such as
locating video data source, playing video, video image acquisition and processing and so on had been expatiated in
detail. The operation results of the system show that this method is fully compatible with common video capture device.
At the same time the system possesses many excellences as lower cost, more powerful, easier to develop and cross-platform
etc. Finally the application prospect of the method which is based on java and JMF is pointed out.
