Embodiment
As shown in Figure 2, the present invention includes two signal sources 1 and 2, two input selectors 11 and 21, two audio process 12 and 22, two outlet selectors 13 and 23, two or more amplifier 14, 24 and 26, two or more output interface 15, 25 and 27 and two or more player 29, 30 and 31, described input selector 11 and 21, audio process 12 and 22, outlet selector 13 and 23, amplifier 13 and 23 and output interface 15, 25 and 27 are connected on central processing unit 3, wherein the output in first signal source 1 and secondary signal source 2 is connected to the input of the first input selector 11 and the second input selector 21, the output of the first input selector 11 is connected to the input of the first audio process 12, the output of the first audio process 12 is connected to the input of the first outlet selector 13 and the input of the second outlet selector 23, the output of the first outlet selector 13 is connected to the input end of the first amplifier 14 or the 3rd amplifier 26, in this figure, the output of the first outlet selector 13 is connected to the first amplifier 14, the output interface 15 and 27 of the first amplifier 14 and the 3rd amplifier 26 is connected with player 29 and 30, the output of the second input selector 21 is connected to the input of the second audio process 22, the output of the second audio process 22 is connected to the input of the second outlet selector 23 and the input of the first outlet selector 13, the output of the second outlet selector 23 is connected to the input of the second amplifier 24 or the 3rd amplifier 26, in this figure, the output of the second outlet selector 23 is connected to the input of the second amplifier 24 and the 3rd amplifier 26, the output interface 25 of the second amplifier 24 is connected with player 31, more than form two-way audio treatment system.Described player 29,30,31 comprises earphone, loud speaker and wireless transmitter module, and described wireless transmitter module is the wireless communication mode such as RF, bluetooth, UWB, WHDI or WIFI.
When dual-audio pattern, first signal source 1 and secondary signal source 2 are input to the first input selector 11 and the second input selector 21, now select the first signal source 1 with the first input selector 11, second input selector 21 selects the signal in secondary signal source 2 to export to the first audio process 12 and the second audio process 22 signal chosen, first audio process 12 processes the signal in number one source 1, second audio process 22 processes the signal in secondary signal source 2, preliminary treatment is carried out through audio process, AD conversion, decoder, filter, equalizer, balance adjustment, special sound effect process, the decodings such as D/A conversion obtain corresponding audio signal, export respectively through outlet selector again, the signal of the first signal source 1 is now exported with the first outlet selector 13, the signal that second outlet selector 23 exports secondary signal source 2 is described, this selection can control to exchange by central processing unit 3 according to actual needs, through the audio signal location A audio signal that the first signal source 1 of the first outlet selector 13 output obtains, after the first amplifier 14 amplification process, be input to player 29 through output interface 15 export, the audio signal location B audio signal obtained through the secondary signal source 2 that the second outlet selector 23 exports, after the second amplifier 24 amplification process, send output interface 25 to be input to player 31 export, simultaneously B audio signal can be amplified through the 3rd amplifier 26 and is input to player 30 through the 3rd output interface 27 after process and export, because of the corresponding two-way player of B audio signal, only need a road interfaces in actual applications, in order to reach this effect, when output interface 25 works, 3rd amplifier 26 quits work or enters standby mode, therefore output interface 25 is only had to work, when output interface 27 works, the second amplifier 24 quits work or enters standby mode, therefore only has output interface 27 to work, and to sum up, can reach and play two paths of signals source simultaneously under dual-audio tupe.
Under single audio frequency pattern, under being the single-image broadcasting situation of traditional tv, central processing unit 3 selects a road audio process to process the signal that front end inputs, an other road audio process is in standby or closed condition, signal after audio process process arrives the second amplifier 24 and the 3rd amplifier 26 through the second outlet selector 23 as B audio frequency, it is same that according to different players, whether whether the corresponding amplifier of job control works, in this case, A road audio frequency can be closed along separate routes, first outlet selector 13 does not export A road, also B road can be followed, namely A audio frequency and B audio frequency are consistent.Same front end also can control to carry out selection by central processing unit and exchange.
As shown in Figure 3, be wherein a kind of execution mode of the present invention, player 29 corresponds to the first earphone, and player 31 corresponds to the second earphone, and player 30 corresponds to loud speaker.Concrete signal processing method is consistent as mentioned above, when dual-audio pattern, first signal source 1 and secondary signal source 2 are input to the first input selector 11 and the second input selector 21, export the first signal source 1 signal with the first input selector 11 now, second input selector 21 exports secondary signal source 2 signal, and to the Correlated Signals that corresponding audio process exports, such first audio process 12 processes the signal of the first signal source 1, consistent with traditional television operation method, in this case, A audio frequency can be closed along separate routes, namely the first outlet selector does not export A road, also B road can be followed, namely A audio frequency and B audio frequency are consistent.Also can control to carry out selection by central processing unit 3 in the front end of input and output equally to exchange.Such process just can reach the effect of compatible traditional tv user operation habits.
As shown in Figure 4, for another embodiment of the invention, scheme is by earphone 29 and 31 and be replaced by wireless transmitter module, through wireless transmitter module, wired voice modulation is transferred the audio frequency after front-end processing to wireless signal to transmit, transmission method can be RF, bluetooth, the multiple radio transmitting method such as UWB, WHDI.Main audio control method is substantially identical with earlier embodiments one, and wireless transmitter module 29 and 31 operation can notify central processing unit 3, and central processing unit 3 also can control the operating state of wireless transmitter module 29 and 31.When wireless transmitter module 31 works or earphone 32 has earphone to access time, then output interface 25 and 28 notifies that the second amplifier 26 control loudspeaker 30 does not carry out work, in the application of reality, can need the collocation carrying out various pattern according to user.
As shown in Figure 5, for user of the present invention need adjust its watch the operational flowchart of signal source program audio, first confirm which kind of image mode is system be in, if single-image pattern, then carries out traditional remote controller operation; If two image mode, then need to enter two screen operation pattern and adjust.System can arrange the button of a switch dual screen control system at remote controller, when under two image mode, the corresponding dual user of two picture, when wherein a user needs the audio frequency of the signal source program of the passage adjusting its viewing time, it can by clicking the button of switch dual screen control system, then observe current picture and whether have relevant OSD prompting, if do not seen, illustrate that current control is not at user's current channel picture but at another one picture, if now carry out parameter adjustment, what adjust is another one passage, in this case, user clicks the button of switch dual screen control system again, active user just can see the relevant prompting of OSD on the picture of its viewing, user obtains the control of current channel, again according to normal adjustment signal method and its frame parameter received of adjustable.
