Embodiment Construction

[0013] The present invention relates to a system by which a user of a home entertainment system can control multiple audio and video devices from a master or central control station called an audio-video platform (AVP). Audio-video equipment is a general term used to describe the electronic components of home entertainment systems such as satellite STB, TV monitor, DVHS VCR, CD player, etc. Many users have traditional audio-visual equipment that does not have a digital link (ie, VHS-VCR or tuner / amplifier). On the other hand, many users purchase audio-visual equipment that use digital links to transmit compressed audio and video signals and communicate with other audio-visual equipment through interconnecting buses.

[0014] Fig. 1 shows a home AV network 100 according to an exemplary embodiment of the present invention. Network 100 includes nine devices, digital VHS (DVHS) video recorder 104, open cable STB108, high-definition digital satellite system (HD-DSS) receiver 112, Natio...

Abstract

An audio-video platform (AVP) performs as a master controller to interconnect other AV devices and provide unified control of all the AV devices connected to it. The AVP receives all control signals from users and controls slave mode AV devices via an IEEE-1394 bus and master mode AV STBs by using an infrared (IR) blaster, having a command set equivalent to the infrared remote control of the master-mode AV device. The AVP also controls legacy devices via the IR blaster. The AVP has on screen display (OSD) and provides unified graphic user interface (GUI) for connected AV devices. The AVP can transfer compressed AV signals for processing and display in one common format, making it possible to display video from all AV devices.

Description

Technical field [0001] The invention relates to the field of audio-video entertainment systems. More specifically, the present invention relates to the main control of various audio-video components combined by bus transmission commands and infrared transmission commands. Background technique [0002] A typical home audio-video system includes a variety of electronic components. For example, a radio, a compact disc (CD) player, a digital versatile disc (DVD) player, a pair of speakers, a television (TV) receiver, a home video system-video cassette recorder (VHS-VCR), etc. These typical components are connected to each other by cables, and one of the components is often considered to be the central or main component of a home audio-video system. The radio is usually used as the central element because it includes an AM / FM tuner, multiple amplifiers, sound adjustment capabilities, and multiple conversion functions. There are control buttons and switches on the panel of the receiver...
