NEC’s Approach Toward IEEE1394 Devices
■ IEEE1394 High-Speed Serial Bus Most Powerful as Interface for Multimedia
Network
Recently, the trend towards handling data such as video and sound as digital content in home electronics
has been increasing due to the start of digital broadcasting and the digitization of AV systems. At the same
time, standards for multimedia networks have advanced and are being applied on a global scale. As a result,
the demand for a high-speed interface that can be used to integrate and connect AV systems and computer
peripherals has grown.
The IEEE1394 high-speed serial bus is an interface that can be used to transmit and receive multimedia
information between multiple systems. It has a function that guarantees bandwidth, which is essential for
transmitting multimedia signals, a wide bandwidth of 100 to 400 Mbps, and has already been employed as
an external interface in digital AV systems such as digital video camcorders and PCs. This interface is also
considered the most powerful candidate for realizing multimedia home networks in the future (see Figure 1).

■ IEEE1394 Becoming the Standard of the Next Generation
Figure 2 illustrates the recent trends in standardization of the IEEE1394 high-speed serial bus. IEEE13941995 standard specifications are used for digital camcorders. P1394a standard specifications are used for
PCs and digital AV devices. Deliberations about the P1394a specifications were concluded this year and the
IEEE1394a-2000 standard was established. These specifications, however, assume the use of metal cables,
and therefore, the transmission distance is limited to a maximum of 4.5 m because of electromagnetic radiation and signal attenuation. Consequently, these specifications are not suitable for networks such as multimedia
home networks. Therefore, specifications that can extend the transmission distance and handle information
at higher speeds have been under evaluation. One standard that extends the transmission distance and
offers an increase in speed is called P1394b and is currently under deliberation. In addition, a standard
called P1394.1 is also under consideration for a bridge specification that is used to separate equipment that
should not be included in a network, or to segment a network into individual rooms in a house.

■ NEC’s IEEE1394 Solution for the Multimedia Home Network Age
NEC is developing and commercializing new LSIs as standardization of IEEE1394 progresses, and is involved in research and development and the standardization of transmission technologies for multimedia
home networks. Figure 3 shows a multimedia home network using IEEE1394. A safe, low-cost plastic
optical fiber (POF) with an acrylic resin core will be used for connection between rooms that are far apart.
Already NEC is offering products that support long-haul IEEE1394 transmission technology, and has been
successful in research and development of other core technologies for home networks. NEC will continue
developing solutions to support the development of its customer’s systems and applications.
