Certainly, the function of detecting unit also can be arranged in the television set control unit, is directly removed to detect the input port of audio channels switching unit and video channel switch unit by control unit.
Shown in Fig. 2 is the example of the control unit of television internal DVD unit as command unit, wherein, DVD unit output also is connected on the switch unit input, the control unit of DVD unit links to each other by string line with the control unit of television set, control unit judgement DVD video disc by the DVD unit is play/is stopped, and notify the control unit of television set with corresponding information, the control unit of television set is according to the switching from the information Control television set receiving mode of the control unit of DVD unit.
Be that the present invention is described in detail for example to automatically switch to the DVD pattern below.
At first, realize that in the mode that detects audio channels switching unit, video channel switch unit input port it is that example illustrates method of the present invention that television set automatically switches to the DVD pattern.When DVD player insertion video disc is play the video disc program automatically, the signal of DVD player broadcast program passes through holding wire, as by being connected the holding wire of television set AV terminal or high definition terminal, be transferred to television set, the detecting unit that is provided with in the television set detects the input port of switch unit, when this detecting unit detects the corresponding port in signal (promptly showing as curtage) when input, the instruction of sending the pattern that switches to described port correspondence to control unit, arranged.For example DVD player is connected television set AV2 terminal, when detecting AV2 Voice ﹠ Video terminal the signal input is arranged, and then switches under the AV2 pattern, has so just realized that television set automatically switches under the AV2 pattern, and the user can watch the DVD program of DVD player broadcast.
Below the changing method under this mode is elaborated, as shown in Figure 3, may further comprise the steps:
Step 301: under the OSD menu input port that can automatically switch being set is the automatic switchover effective efficiency.
Can be provided with respectively at the input port of each audio channels switching unit, video channel switch unit.As the AV1 port being set for automaticallying switch, the AV2 port is for automaticallying switch.When being provided with, according to the prompting of OSD menu, the automatic transfer switch of the port that selection can be switched is for effective.When certain port switch places " effectively ", can trigger automatic switchover, when certain port switch placed engineering noise, then expression can not trigger automatic switchover.For the port that is set to engineering noise, mask detection to this port, whether this port connected equipment has signal can not switch to this port.
Step 302: detecting unit detects the port that is set to " effectively ", trigger switching signal when detecting the DVD signal, report control unit, and can send information by control unit before automaticallying switch selects to user prompt, can select whether to switch, after receiving the affirmation information that the user sends by remote controller, execution in step 303.
Prompting user's mode can be: control unit shows the pattern that whether switches to the current correspondence of DVD by display screen, as the AV2 pattern; In addition, when television set is supported picture-in-picture, also can further show the menu of selecting for the user: as, switch to AV2 pattern all over the screen or switch to picture-in-picture mode and play the AV2 signal program, or do not switch.
Step 303: control unit control audio passage switch unit, video channel switch unit are connected the corresponding input end mouth, are about to television set and switch under the associative mode of DVD playing back, promptly switch under the pattern of AV2 in this example.When supporting above-mentioned pair of image mode (as picture-in-picture, picture out picture), according to user's selection, television set control unit may command enters two image modes, and plays the program of described AV2 port by one of them picture.
By detection mode to different input ports, television set can be realized only switching at the port that signal is arranged, as, when only detecting audio input port signal arranged (as put into be CD, MP3 dish), after reporting control unit, control unit is only given an order to the audio frequency switch control unit and is only carried out the switching of voice-grade channel, keeps the picture program not switch.Corresponding is when only carrying the CD of picture when what put into, only can detect video port signal is arranged, after the information that control unit reception detecting unit reports, only give an order to video control unit and only carry out the switching of video channel, television set keeps the sound of current program to continue to play.

Specifically, as shown in Figure 4, this handoff procedure may further comprise the steps:
Step 401: the input port that the employed audio channels switching unit in built-in DVD unit, video channel switch unit are set under the OSD menu is the automatic switchover effective efficiency.
The control unit of step 402:DVD unit is judged and is put into the DVD video disc and when playing, send the control unit that signal is given television set.
Certainly after the television set control unit received signal, also can add the step whether the access customer selection is switched and whether adopted the picture-in-picture mode to switch.
Step 403: tv audio passage switch unit, the video channel switch unit input of television set control unit control appointment are connected, and promptly switch under the receiving mode of the correspondence that receives the DVD player signal.
And, as mentioned above, the DVD unit can identify the form of the video disc of putting into, video disc as forms such as VCD/CD/MP3/PIC, can represent the video disc form to send to the television set control unit by DVD unit controls unit with two digits, the television set control unit be selected to carry out audio frequency or/and the switching of video channel according to form.Can certainly carry out audio frequency or/and the switching of video channel by the DVD unit notice that sends instructions, as two digits, one is used for corresponding video, whether one is used for corresponding audio frequency, switch with 0 and 1 representative, switches as 11 expression video/audios, 10 expression video switchs, 01 expression audio frequency switches.The television set control unit switches accordingly according to the instruction of DVD unit.Only can realize switching like this, or only to the switching of picture, perhaps two passages switch simultaneously to sound.
Switch back the process of previous status for television set, may further comprise the steps: the DVD blackout that detects the AV2 terminal when detecting unit, for example when DVD player enters holding state or shutdown, signal output is not being arranged, detecting unit then sends signalisation television set control unit; The television set control unit switches back former television set pattern.Concrete handoff procedure repeats no more owing to principle and last similar.
For another example, under the pattern of non-reception DVD correspondence, when the user inserted the DVD video disc, the automatic perception in DVD unit had video disc to insert, DVD unit starting and by input/output port notice television set control unit, to switch under the corresponding receiving mode.When playing programs finished, detecting unit detected programme signal and disappears, and notice television set control unit is to switch back original television set receiving mode.When the user sees TV, when wanting to use the built-in DVD unit to see video disc, then directly video disc is inserted into the DVD unit like this, television set jumps to DVD playing back video disc under the corresponding receiving mode automatically.
In addition, when the control unit of DVD player and the communication of television set control unit, the content of communication can be abundanter, as sending instruction by the control unit of control unit to the DVD unit of television set, for example when television set leaves the DVD pattern, as be transformed into television set pattern or when shutdown, and then can send an instruction to DVD unit controls unit, after receiving the unit, DVD enter halted state or holding state.
