Description

Home network server, apparatus and method for controlling AV system

The present invention relates to a home network server, an AV control apparatus and a method, and more particularly, to a home network server, an AV control apparatus and a method for directly operating AV devices on an AV network.

Recently, with the development of digital TV-centered home network technology, DVD players, home theaters, digital camcorders, set top boxes (STBs), and various video and audio devices are being distributed to each home. In particular, in the home theater, a DVD player, a plasma display panel (PDP), an audio video (AV) amplifier, a set-top box, and a plurality of speakers form one system, and each component forms a home network.

In addition, the XHT (eXpandable Home Theater), a home network solution adopted as a standard of the Consumer Electronics Association (CEA), is used in the IEEE 1394 cable and the Internet for the most stable transmission of a large number of high definition (HD) signals. It is a technology using the communication standard (Internet protocol) to be used, and the user can conveniently control multiple TVs as well as video and audio devices connected to the TV. IEEE 1394 is a transmission technology standard between digital devices that connects communication devices, computers, and home appliances in a single network, and transmits and receives multimedia data at high speeds from 100 Mbps to 1 Gbps. In addition, up to 63 devices can be connected in series per bridge and communication is possible even if one device is interrupted in the middle.
