The IEEE1394 is a favorable protocol for A/V networks recently in home and there are two types of transmission in this protocol which are asynchronous and isochronous. The more nodes participate in the IEEE1394 network, the more problems of resource exhaustion and connection repetition may occur. So this paper proposes a middleware for isochronous connection management and reliable multimedia data transmission in the IEEE1394-IEC61883 based home networks. In this paper, proposed middleware is supporting the various types of isochronous connection, guaranteeing the reliability of isochronous connection and providing the characteristic of a real-time data transmission. We support CORBA API for multimedia service and the proposed architecture was implemented using a test-bed and we verified the proposed architecture in a test-bed.

It is necessary to have enough transmission capacity for advanced internet techniques and various digital home appliances networking. Home appliances interface IEEE1394 technique has much wealthy transmission skill. IEEE1394 is using home appliances through various information form image and voice change data real time print out. In this paper, AVC CTS technology and IEEE1394 technology are introduced. Digital Video Camera includes compression format using DV. System composition control is consisted of protocols like IEC-61883 and AV/C command set standard.

Recently the interest in digital home services and its related technology has increased rapidly. Multimedia data transmission between digital devices that are connected to home network is essential function. This paper presents the design and implementation of multimedia streaming system based on IEEE1394 in Linux environment. The key features of proposed system are as follows. First, it can transmit and receive not only DV format data but also MPEG2-TS format data through IEEE1394 bus. Second, it uses device drivers that handling IEEE1394 and IEC61883 protocol transparently to reduce the complexity of communication program. Third, it applied capacity adaptation technique considering various specifications of PCs to get smooth streaming for HD data. These characteristics are tested on testbed of IEEE1394 based home network. The proposed media streaming technique can be used as a home media sever in Linux environment.
