Embodiment
As shown in Figure 2; The utility model comprises 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 above amplifiers 13 and 15,25 and 27 and two above players 29,30 and 31 of 23, two above output interfaces; 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 be connected on the central processing unit 3; Wherein the output in first signal source 1 and secondary signal source 2 is connected to the input of first input selector 11 and second input selector 21; The output of first input selector 11 is connected to the input of first audio process 12; The output of first audio process 12 is connected to the input of first outlet selector 13 and the input of second outlet selector 23; The output of first outlet selector 13 is connected to the input end of first amplifier 14 or the 3rd amplifier 26; Output with first outlet selector 13 among this figure is connected to first amplifier 14; The output that is connected with player 29 and 31, the second input selectors 21 on the output interface 15 and 25 of first amplifier 14 and the 3rd amplifier 26 is connected to the input of second audio process 22, and the output of second audio process 22 is connected to the input of second outlet selector 23 and the input of first outlet selector 13; The output of second outlet selector 23 is connected to the input of second amplifier 24 or the 3rd amplifier 26; Among this figure the output of second outlet selector 23 is connected to the input of second amplifier 24 and the 3rd amplifier 26, is connected with player 41 on the output interface 25 of second amplifier 24, more than constitute the two-way audio treatment system.Described player 29,30,31 comprises earphone, loud speaker and wireless transmitter module, and described wireless transmitter module is wireless communication modes such as RF, bluetooth, UWB, WHDI or WIFI.
When double-tone frequency pattern, first signal source 1 is input to first input selector 11 and second input selector 21 with secondary signal source 2, and is existing with first input selector, 11 selections, first signal source 1; Second input selector 21 selects the signal in secondary signal source 2 to export the signal that has chosen to first audio process 12 and second audio process 22, and first audio process 12 is handled the signal in number one sources 1, and second audio process 22 is handled the signal in secondary signal sources 2; Carry out preliminary treatment through audio process, AD conversion, decoder; Filter, equalizer, balance adjustment; Special sound effect is handled, and decodings such as D/A conversion obtain the corresponding audio signal, exports through outlet selector respectively again; Existing signal with first outlet selector, 13 outputs, first signal source 1; The signal in second outlet selector, 23 output secondary signal sources 2 describes, and this selection can be changed through central processing unit 3 controls according to actual needs, the audio signal location A audio signal that first signal source of exporting through first outlet selector 13 1 obtains; Export through being input to player 29 through output interface 15 after first amplifier, 14 processing and amplifying; The audio signal location B audio signal that the secondary signal source 2 of exporting through second outlet selector 23 obtains is exported through having sent output interface 25 to be input to player 31 after second amplifier, 24 processing and amplifying, and the B audio signal can be through being input to player 30 outputs through the 3rd output interface 27 after the 3rd amplifier 26 processing and amplifying simultaneously; Because of the corresponding two-way player of B audio signal; In practical application, only need one road interface work to get final product, in order to reach this effect, when output interface 25 work; The 3rd amplifier 26 quits work or gets into standby mode, therefore has only output interface 25 work; When output interface 27 work, second amplifier 24 quits work or gets into standby mode, therefore has only output interface 27 work, to sum up, under double-tone frequency tupe, can reach and play the two paths of signals source simultaneously.
Under the single audio frequency pattern, be under the single-image broadcast situation of traditional tv, central processing unit 3 selects one road audio process that the signal of front end input is handled; Other one road audio process is in standby or closed condition; Signal after handling through audio process arrives second amplifier 24 and the 3rd amplifier 26 through second outlet selector 23 as the B audio frequency, and whether same whether work according to different players is controlled corresponding amplifier and worked, under this state; A road audio frequency can be closed along separate routes; First outlet selector 13 is not exported the A road, can follow the B road yet, and promptly A audio frequency and B audio frequency are consistent.Same front end also can be selected to exchange through central processing unit control.
As shown in Figure 3, be wherein a kind of execution mode of the utility model, player 29 corresponds to first earphone, and player 31 corresponds to second earphone, and player 30 corresponds to loud speaker.The concrete signal processing method is consistent as stated, and when double-tone frequency pattern, first signal source 1 is input to first input selector 11 and second input selector 21 with secondary signal source 2; Now with first input selector 11 output, first signal source, 1 signal, second input selector, 21 output secondary signal sources, 2 signals, and to the Correlated Signals of corresponding audio process output; Such first audio process 12 is handled the signal of first signal source 1, and is consistent with traditional television operation method, under this state; The A audio frequency can be closed along separate routes; Promptly first outlet selector is not exported the A road, can follow the B road yet, and promptly A audio frequency and B audio frequency are consistent.Also can select to exchange at the front end of input and output equally through central processing unit 3 controls.Handle the effect that just can reach compatible traditional tv user operation habits like this.
As shown in Figure 4; Be the another kind of execution mode of the utility model, scheme with earphone 29 and 31 be replaced by wireless transmitter module, will pass through audio frequency after the front-end processing and transfer wired voice modulation to wireless signal through wireless transmitter module and transmit; Transmission method can be RF; Bluetooth, UWB, multiple radio transmitting method such as WHDI.Main audio frequency control method and front execution mode one are basic identical, can notify central processing unit 3 in the time of wireless transmitter module 29 and 31 work, and central processing unit 3 also can be controlled the operating state of wireless transmitter module 29 and 31.When wireless transmitter module 31 work or earphone 32 had earphone to insert, then output interface 25 and 28 notified second amplifier, 26 control loudspeakers 27 not carry out work, in the application of reality, can carry out the collocation of various patterns according to user's needs.
As shown in Figure 5, for the utility model user need adjust the operational flowchart of its signal source program audio of watching, which kind of image mode is at first affirmation system be in, if the single-image pattern is then carried out traditional operating remote controller; If two image modes then need get into two screen operation patterns and adjust.System can be provided with the button of a switch dual picture control system at remote controller, when under two image modes, and the corresponding dual user of two pictures; When wherein a user need adjust the audio frequency of the signal source program of its passage of watching, it can be through clicking the button of switch dual picture control system, and whether observe current picture then has relevant OSD prompting; If do not see; Explain present control not the user when prepass picture but at the another one picture, what adjust if carry out parameter adjustment this moment is the another one passage, in this case; The user clicks the button of switch dual picture control system again; The active user just can see the relevant prompting of OSD on its picture of watching, the user obtains the control when prepass, can adjust the frame parameter that it receives according to normal adjustment signal method again.
