Abstract

There is provided an AV system including a display device and a plurality of video devices connected to the display device, wherein remote control operation of the video devices can be performed toward the display. At the side of display (100), a manufacturer code and a device code are read from all the STB (110 to 112) connected to the display (100) to create a table of connected devices. When a user depresses a button of a remote controller, a remote control code issued from the remote controller is received. The manufacturer code and the device code contained in the remote control code are searched in the table of the connected devices. A selector (105) is switched so that a reception interface connected to the STB whose manufacturer code and the device code are matched with the searched ones is connected to a display section (102) and the AV data transferred from the STB is displayed and reproduced on the display section (102).

Embodiment
Below, with reference to the description of drawings embodiment of the invention.It should be noted that,, be not limited to this embodiment at the embodiment of this expression example only.
(embodiment 1)
Below, the AV system of the embodiment of the invention 1 is described.
Fig. 1 is the figure of structure of the AV system of the expression embodiment of the invention 1.
In Fig. 1, the 100th, display shows the image of importing, or output sound.The 101st, remote controller, be attached to describe later respectively connect instrument.The 102nd, display part, displayed image, output sound for example is CRT or liquid crystal panel, plasma scope and loud speaker.The 103rd, the remote control acceptance division receives the signal from remote controller 101.The 104th, the control part of display, the control display is all, for example is CPU.The 105th, selection portion is selected from pictorial data that is connected a plurality of instruments on the display and voice data.The 106th, memory, the tabulation of the connection instrument that storage is described later.107～109 is first～the 3rd receiving interfaces.It should be noted that, in following embodiment, be digital interface, wherein, is example with HDMI (High DefinitionMultimedia Interface), describes.110～112 is the first～the Three S's TB (Set Top Box), receives broadcasting, picture reproducing and sound.It should be noted that, at this, as connecting instrument, be that example describes with STB, still, if the instrument of DVD, VTR, game machine, other output images just can be arbitrarily.In addition, STB can be that STB is used in BS/CS broadcasting, can be surface wave STB, can be game machine of use STB.113～115th, HDMI cable, transmission diagram image data, voice data, control signal.It should be noted that, the situation that connects display and STB with the HDMI cable is described, but can is DVI (Digital Visual Interface).
Fig. 2 is the block diagram of the structure of expression the one STB110.At this, the STB of receiving digital broadcast is described.
In Fig. 2, the 1001st, transmission interface is connected with the receiving interface of display 100, to display 100 output images, sound.During for digital interface, for example be the transmission interface of HDMI.The 1002nd, control part is controlled each piece in the STB110.The 1003rd, memory is stored manufacturer code and the instrumented code of a STB110.The 1004th, antenna, the electric wave of receiving digital broadcast.The 1005th, tuning portion carries out the demodulation of broadcast wave.The 1006th, preposition portion carries out error correction to the signal of demodulation, reproduces TS (transmitting stream).The 1007th, the TS decoding part is from extracting the multiplexed TS of a plurality of programs out the packets of information (image, sound, data etc.) of user selected program.The 1008th, the AV decoding part carries out by the pictorial information bag of TS decoder extraction and the expansion of acoustic information bag the picture intelligence and the voice signal of output numeral.
It should be noted that the 2nd STB111, Three S's TB112 and a described STB110 are same structure, so elliptical structure figure.
Below, the structure of HDMI is described.Fig. 3 represents the structure of HDMI.HDMI is made of sending part (transmitter) and acceptance division (receiver), and sending part is that the instrument of demonstration output images such as the instrument that STB or DVD, VTR etc. become image, sound source has, the acceptance division display or sound has.Connect by the HDMI cable between sending part and the acceptance division.
The 1301st, sending part carries out the TMDS coding to picture intelligence (Y, Pb, Pr) and audio signal (IEC958), exports to acceptance division 1304 with the form that is suitable for high-speed transfer.The 1302nd, the TMDS encoder about pictorial data, is transformed to serial 10 * 3 passages to the pictorial data of parallel 8 * 3 passages, about voice data, parallel 4 voice datas is transformed to 10 of serials.The 1303rd, send control part, control sending part 1301.The 1304th, acceptance division carries out TMDS decoding to the pictorial data of sending from sending part 1301, voice data, reproduces pictorial data, the voice data of base band.The 1305th, the TMDS decoder is transformed to parallel 8 to the pictorial data of 10 of serials, and the voice data of 10 of serials is transformed to parallel 4.The 1306th, receive control part, control acceptance division 1304.The 1307th, instrument control line, the control signal that transmission people's livelihood instrument is used.The instrument control line for example is CEC (Consumer ElectronicsControl) line.The 1308th, DDC (Display Dada Channel) line, the control signal of transmitting and displaying device.
