At this, receiving system 2 is described with reference to Fig. 2.Fig. 2 is the block diagram of summary structure of the receiving system of expression embodiments of the present invention 1.As shown in Figure 2, this receiving system 2 has: the antenna element 2a and the receiving system main body 2b that have connected above-mentioned a plurality of antenna A1～An.Such antenna element 2a is connected by adapter 2c with receiving system main body 2b, and antenna element 2a has demodulation control part 20 and demodulation section 21, and the high-frequency signal that receives is demodulated into baseband signal S2.Therefore, even under the situation that changes antenna amount or under the situation about receiving by different wireless frequencies, by changing antenna element 2a, receiving system main body 2b also can import same baseband signal S2.
The concrete condition of receiving system 2 then, is described.Antenna element 2a has: antenna switching part 23, and it connects a plurality of antenna A1～An, carries out the switching of antenna; Demodulation section 21, it carries out demodulation to the high-frequency signal that receives via antenna switching part 23; Demodulation control part 20, its demodulation action to demodulation section 21 is controlled; Signal strength detection portion 22, it detects from the signal intensity of the high-frequency signal of antenna switching part 23 inputs the receiving intensity of (promptly, by any wireless signal that receives a plurality of antenna A1～An); Switch 24, it is to the high-frequency signal of any output in demodulation section 21 and the terminal 25 via 23 inputs of antenna switching part; And the terminal 25 that is connected with switch 24.By switch 24 being switched and monitoring, carry out the diagnosis of the abort situation of antenna element 2a thus by 25 pairs of high-frequency signals of terminal.
The high-frequency signal that the antenna switching part 23 of antenna element 2a receives via a plurality of antenna A1～An to 22 outputs of signal strength detection portion, the signal intensity of the high-frequency signal of being imported detects in signal strength detection portion 22, to receiving system main body 2b output antenna strength signal S1.Antenna switching part 23 input switching signal SB select to switch to an antenna from a plurality of antenna A1～An, export the high-frequency signal that is received by the antenna that is switched via switch 24 to demodulation section 21.Demodulation section 21 is demodulated into baseband signal S2 according to the control signal SA from 20 inputs of demodulation control part with high-frequency signal, to receiving system main body 2b output baseband signal S2.Import control signal SD from receiving system main body 2b, under the situation of control signal SD indication starting beginning, demodulation control part 20 is according to the demodulation action of control signal SA control demodulation section 21.Switch 24 is according to control signal SC control change action, switches between demodulation section 21 sides and terminal 25 sides and exports high-frequency signal via 23 inputs of antenna switching part.
Receiving system main body 2b has: signal processing part 29, and it is imported by the baseband signal S2 after the antenna element 2a demodulation, and carry out this baseband signal S2 is converted to digital signal and generate the signal processing of view data, storage part 28, it stores this view data at least; Display part 27, it shows the various information of output; And control part 26, it is controlled above-mentioned each one, simultaneously antenna element 2a is driven control.
The control part 26 of receiving system main body 2b is exported switching signal SB, the antenna change action of control antenna switching part 23 according to the antenna strength signal S1 that is imported to antenna element 2a.In addition, control part 26 is to antenna element 2a output control signal SD, and the demodulation action of beginning demodulation section 21 obtains view data according to the output of signal processing part 29, to display part 27 output image signal SS1, comprise the data signal SS2 of view data simultaneously to storage part 28 outputs.Display part 27 received image signal SS1 and display image data, storage part 28 input data signal SS2 and storing image data.
