This paper propose a hardware architecure of multimediasysgem for integrated processing of the multimedia data such as audio and video, and describes on the design and implementation of multimedia integrated processing Unit. The unit comprises most commonly needed multimedia processing function for computer-based video conference: audio-visual datacapture, playback, compression, decompression as well as interleaving/disinterleaving of compressed audio-visual data. The proposed architecture minimizes the CPU overhead that might be caused by multimedia data processing and assures the fluent data flow among system components. Also, this unit is tested and analyzed under the computer-based video conference to confirm the multimedia unit of proposed architecture using communication protocol and application software through Ethernet and FDDI (Fiber Distributed Data Interface) networks.

The digital multimedia era has come and almost everyone creates and publishes multimedia contents over the internet. When the available amount of multimedia content is exponentially increasing, searching through the sea of the multimedia content is a big problem. In this paper, we present MPEG Query Format (MPQF), which is a new standard for multimedia query language based on XML-schema. MPQF provides a standardized interface for users of heterogeneous multimedia information service providers to access their services of choice in a homogeneous way.

Multimedia conference systems are classified into the tightly coupled conference and the loosely-coupled conference, the former is a peer-to-peer-conference or multi-point-conference based un the ITU-T H.323 standard, and the latter is the H.332 standard extended from the ITU-T H.323 standard. Loosely-coupled conference based on the H.332 standard is composed of small participants with the capacity of the send-receive mode and large participants with the capacity of the receive-only mode. In the H.332 conference, a subject and a media type of the multimedia conference is pre-announced for conquest of the difficulty of capability negotiation, and used SDP of IETF for that. Therefore, the H.332-conference can conquer a defect of the H.323 multimedia conference scalability. This paper analyzes H.332 standard for the loosely-coupled conference and describes an implementation of the H.332 multimedia conference systems.

To transmit multimedia information efficiently and use it in realtime, it needs a private multimedia terminal for service type. But multimedia information terminal was developped for of offered service type in case by case. Accordingly, general multimedia terminal have not been developed yet. Multimedia database structure and standard communication protocol must be designed first to develop the general multimedia terminal. Multimedia database structure needs to store the various multimedia information consistently and, standard communication protocol access the database transparently. In this paper, we design a multimedia database structure and communication protocol that are able to access the multimedia information on distributed database servers in the network.
