In this paper, an implementation example of Java based MPEG-4 system that follows MPEG-4 standard protocols in order to provide multimedia-messaging service is introduced. The multimedia-messaging service is a wireless LAN based wired and wireless service that delivers multimedia contents including video and audio information. Detailed Methods to develop a MPEG-4 system like technology of MPEG-4 system implementation, definition for wired and wireless multimedia service, DMIF implementation, and mp4 file Parsing are described.

Informations of multimedia centering in the images, are combined acoustic and letter, etc. Although the network advances and the capacity of the storage media extends, these huge informations will not be able to accommodate. From meaning which is like this, International standards for the compression and a multiplexing of image, acoustic and voice H261 where admits standard, JPEG, JBIG, MPEG-l, MPEG-2, MPEG-4 and H263, G series etc, are core techniques of multimedia. At initial step of the base technique which creates the base of like this multimedia service time, we developed the real-time MPEG-4 transmission systems to provides real-time MPEG-4 multimedia services. This system means becomes the base technique which hereafter is developed and is applied various system. This system Will be able to apply from a videoconference, a building protection system and a VOD video system to use the Internet. And, They, the image sensing, embedded linux, and MPEG4 software, will become sourceful technique to develop the different system.
