HAVi is a standard, developed by several leading electronics and computer manufacturers, that allows a number of different home-entertainment and communication devices to operate from a single controller device such as your TV set. The specification uses IEEE 1394 (FireWire or i.LINK) as the interconnection medium. With a HAVi-based system, users of home appliances will be able to add new devices without going through complicated installation processes or wading through arcane instruction manuals or help files. Personal computers may be part of a HAVi-based home system, but it will not be necessary for such a system to function. HAVi is a digital AV networking initiative that provides a home networking software specification for seamless interoperability among home entertainment products. Equally important, the HAVi specification is AV-device-centric, so it has been designed to meet the particular demands of digital audio and video.
