Control unit 120 is used to discern the button operation from remote controller/keyboard, the switching of control audio passage switch unit 130, video channel switch unit 150.For example, when receiving the user when selecting the AV1 pattern, then control audio passage switch unit 130 conducting AV1 audio frequency terminals are to sound processing unit 140, and control of video passage switch unit 150 conducting AV1 video terminal are to video disposal unit 160.
Among the present invention, control unit 120 further comprises audio frequency switch control unit 121 and video switch control unit 122, be used for realizing control respectively to audio channels switching unit 130 and video channel switch unit 150, can realize independent control like this to the audio frequency switch unit, promptly can be implemented under the situation that video do not switch, separately switch audio.
Below, be under the VGA state with TV, when the user browsed the text of TV demonstration or browses image file, the user wished that it is example that TV can be play the AV audio frequency, is described the audio switching method under the different mode provided by the invention.Can an audio selection submenu be set in the OSD menu that TV provides in advance, the audio input port that is shown to each different receiving modes of user is to select.The user operates by the keyboard (being control panel) of remote controller or TV, just can access this menu, with the audio frequency of selected current desirable other patterns.Be elaborated below:
The first step: the user presses the remote-controller function key, the control unit 120 of TV receives the operation information of remote controller, access the OSD menu, and access the audio selection submenu according to user's selection, this submenu has been listed all each receiving mode and choice box, also can only list effective receiving mode and choice box.
That says here effectively refers to the situation that the signal input terminal that detects under the receiving mode has signal input, or detects the situation that corresponding input end has inserted external equipment.For preceding kind of situation, simple implementation method can be that a detecting signal unit is set, and input terminal is carried out voltage (or electric current) input, then has been considered as the signal input when detection has voltage (or electric current) signal to exist, and notice control unit 120.For back kind situation, simple implementation method can be provided with at the input terminal place one when external plug insertion input terminal saltus step be the testing circuit of conducting, this circuit saltus step can pass to control unit 120 with a signal during for conducting, thereby realizes whether the input terminal under this pattern of notice control unit has inserted external equipment.For example when the AV2 terminal did not connect external equipment, then being considered as the AV2 pattern was invalid receiving mode, is shown as unavailable emphasis or does not show this AV2 pattern in the audio selection submenu.
Second step: the user is by remote controller selected receiving mode that it needs in the audio selection submenu, the receiving mode that the audio frequency switch control unit 121 of control unit 120 is selected according to the user, determine that the audio frequency under this pattern inserts terminal, sends switching command to audio channels switching unit 130 then.
In this example, the receiving mode that the user selectes is the AV1 pattern, after then control unit 120 is determined the AV1 audio frequency terminal of AV1 pattern, sends switching command to audio channels switching unit 130.
The 3rd step: audio channels switching unit 130 is according to switching command, and the sub-conducting of audio input end under the AV1 pattern of correspondence to internal sound processing unit 140, is disconnected being connected of current VGA audio frequency terminal and internal sound processing unit 140.Like this, the loud speaker of TV has just played out sound that the AV1 audio input port sends, is signal from the VGA video port and television display screen shows simultaneously.
Wherein, when sound processing unit was supported the output of multichannel input multichannel, also the audio signal of the various modes that the user can be selected inserted sound processing unit simultaneously, exports from multichannel respectively.In this case, allow the user in choice box, to choose a plurality of receiving modes in the audio selection submenu of the OSD menu that provides of TV.Accordingly, 120 control audio passages of control unit switch unit 130 is not with the pairing different audio frequency terminals of the different receiving modes of being chosen conducting going the same way to internal sound processing unit 140 respectively.For example, if television set is supported the output of two-way input two-way, and a road in the two-way output outputs to left speaker, and one the tunnel outputs to right loud speaker, and then left and right sides loud speaker can be play the audio-frequency information from audio input end of two kinds of user-selected receiving modes respectively.As can one the road to left speaker, still be used for playing audio signal from VGA audio input end of VGA pattern, another road is used for playing the audio signal from AV1 audio input end of selected AV1 pattern to right loud speaker.Certainly, can play the sound of different audio input end separately in order to realize left and right sides loud speaker, the circuit that need be docked to loud speaker is changed, for example between the output of the two-way of sound processing unit and left and right sides loud speaker, add switch unit, can realize to send to two loud speakers respectively from the information that export on each road of sound processing unit.
Again for example, when TV is many pictures TV pattern, as when being in the state of picture-in-picture, the user can select the two-way audio of broadcast from double high-frequency head by the audio selection submenu of OSD menu, selected two-way audio is linked into respectively on the two-way of sound processing unit, can realize that then one tunnel audio signal play by left speaker, another road audio signal is by right loudspeaker plays, and this two-way sound is two programs of corresponding picture-in-picture respectively.
As seen from the above, the present invention can realize that TV receives the audio signal of other patterns under a certain pattern, thereby satisfies user's different demands.Play as the audio signal that under the VGA pattern, can play AV pattern or TV pattern or other patterns, can music appreciating, perhaps can play the sound under the TV pattern simultaneously, to understand the current television program content.And for example when TV is many pictures (as picture-in-picture) pattern, can realize switching, perhaps make the different loud speaker of TV play the different pictures corresponding audio respectively at the audio signal of different pictures.
