In this paper. we propose an interactive broadcasting system based on MPEG-4 to provide Interactive services in digital TV broadcast. The proposed system is designed to support various functionalities such as authoringof MPEG-4. encapsulation of MPEG-4 Into MPEG-2 TS (Transport Stream) protocol, synchronization of MPEG-4 with MPEG-2 program. demultiplexing of MPEG-4 from MPEG-2 TS. decoding/rendering of MPEG-4 and interactivity through IP network on ATSC (Advanced Television Systems Committee) platform. The interactive broadcasting system based on MPEG-4 Is used to provide interactive functionality In full for user. and it has a particular advantage of substitution for the ATSC or DVB platform. as well.

We propose video management system based on MPEG-7 for mobile device(MVMS). Most of existing MPEG-7 applications manage MPEG-7 document based on file system in the desktop environment. To contrast them, because the MVMS manages only necessary information using embedded database system for MPEG-7 documents in mobile devices, it can use efficiently lack of the resource in mobile device environment. MVMS supports key image extraction and MPEG-7 document edition function. Moreover, this is possible search and management of multi document because of MVMS manage MPEG-7 data through embedded DB.

The MPEG is the standard of coding moving pictures, and MPEG-1 and MPEG-2 are widely in use. And as the performance of CPU has improved, it is now possible to implement MPEG-1 in software only. This paper introduces the techniques of developing MPEG-1 playback system in software without using hardware on Windows 95 operating system. The implemented MPEG-1 playback system shows an acceptable performance.

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.

Digital contents is used already in near place with us. Contents of MPEG-4 standard is used to process multimedia data in field of communication, computer, broadcasting mobile etc. However, absence of copyright management and protection system and interoperability problem of right system between each corporation happened. Because MPEG establish IPMP(Intellectual Property Management and Protection) system standard in agreement with MPEG-4 system standard, proposed cooperation method to manage and protect copyright. Accordingly, in this paper, put in copyright of authorized contents management and protection extension system implementation adding MPEG-4 IPMP system like plug-in into existing MPEG-4 authorizing tool. Therefore, author edits IPMP information to protect contents or object, and process the information in system and authorize MPEG-4 digital contents that have management and protection sign according to IPMP standard. This system designed and implemented to divided into IPMP information save processor, IPMP information creation processor, media IPPM processor, XMT-A to MP4 converter IPMP extension.

AUI(Advanced User Interaction) interface aims to enhance interaction between various input/output devices and scene descriptions represented by video, audio, and graphic. Recently, MPEG-U part 2 standardization for the AUI interface is under development by MPEG(moving picture experts group). This paper introduces MPEG-U part 2 standard and presents MPEG-U part 2 AUI interface system. The AUI interface system consists of user interface in/output modules and MPEG-U XML generation/interpretation modules. The former and the latter are for UID data handling and XML data processing, respectively. This system MPEG-U standards-based input/output devices and to improve the interaction with the user can be used as a framework. By implementation of the proposed AUI interface system, MPEG-U usage scenario is introduced and it is verified that the AUI interface system conforms to MPEG-U standard.

DMB is a next-generation multimedia broadcasting system that not only enables digital broadcasting services such as transmission of CD-duality audio, traffic information, and real-time stock information, but also allows reception of high-quality digital TV in high-speed driving conditions. In the DMB system, MPEG-2 TS(Transport Stream) multiplex method and MPEG-4 System SL(Sync Layer) have been selected as the delivery layer. In this paper, an efficient interface scheme between an MPEG-2 TS processing hardware and software-implemented MPEG-4 system within a DMB terminal device is proposed.

In restricted resources based on mobile environment, we can use an embedded database technology for management of MPEG-7 data. At this time, some XML clustering methods can be used. But, to improve the performance efficiency better, a new clustering method is need to store effective MPEG-7 document. In this paper, we have designed and implemented a MPEG-7 document management system to store MPEG-7 document effectively in mobile device such as PDA. The system used the 버클리 DB XML as a native embedded XML database system based on the clustering method of MPEG-7 data.

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.
