Fig. 1 is a flowchart illustrating an extended use method of an AV OUT interface according to an embodiment of the present invention.
An extended use method of an AV OUT interface, wherein the AV OUT interface comprises a video output jack, a left channel jack and a right channel jack, and the method comprises the following steps:
s1: acquiring occupation information of the video output jack, the left sound channel jack and the right sound channel jack;
s2: selecting a signal output mode of the AV OUT interface according to the occupation information, wherein the signal output mode comprises an AV OUT mode and a LINE OUT mode;
s3: calling corresponding codes based on the signal output mode;
s4: and executing codes to control the occupied video output jacks, the left channel jacks and the right channel jacks to output corresponding signals.
In the prior art, from the hardware point of view, the jack specification of the AV OUT interface and the jack specification of the LINE OUT interface are consistent, the difference is that the LINE OUT interface does not have a video output jack, but the AV OUT interface and the LINE OUT interface are functionally independent of each other, and the AV OUT interface can only be used for outputting the pictures and sound of the ATV and the AV, and particularly for outputting the signals of the TV channel and the CVBS channel. The LINE OUT interface may be used to output the sound of each channel. The extended use method of the AV OUT interface is applied to a machine, and particularly can be a television. The television has a plurality of signal channels, each signal channel for receiving a corresponding input signal. The extended use method of the AV OUT interface of this embodiment is applied to a television, so that the AV OUT interface on the television can implement both the function of the original AV OUT interface and the function of the LINE OUT interface.
In step S1, the user plugs in the video output jack, the left channel jack, and the right channel jack using the signal lines as needed. Specifically, if the user wants to obtain the pictures and sound of the video of the television, the AV OUT interface can be connected to a display screen by using signal lines to realize signal transmission, in this case, the video output jack, the left channel jack and the right channel jack are all plugged with signal lines, and all three jacks are occupied. If the user wants to obtain the sound of the appointed channel of the television, the AV OUT interface is connected with a sound box by using the signal wire to realize signal transmission, in this case, the video output jack does not have the function, and the signal wire is only plugged into the left sound channel jack and the right sound channel jack. The embodiment forms corresponding occupation information according to the occupation conditions of three jacks of the AV OUT interface.
In step S2, a signal output mode of the AV OUT interface is selected according to the occupancy information acquired in step S1, where the signal output mode includes an AV OUT mode and a LINE OUT mode. Specifically, if the video output jack, the left channel jack and the right channel jack are occupied at the same time, the AV OUT mode is selected as the signal output mode of the AV OUT interface; and if only the left channel jack and the right channel jack are occupied, selecting the LINE OUT mode as the signal output mode of the AV OUT interface.
In step S3, the corresponding code is called based on the signal output mode, where the AV OUT mode and the LINE OUT mode each have a corresponding code.
In step S4, when the signal output mode of the AV OUT interface is selected as the AV OUT mode, executing a code corresponding to the AV OUT mode, and controlling the video output jack, the left channel jack, and the right channel jack to output signals of corresponding signal channels. And when the signal output mode of the selected AV OUT interface is the LINE OUT mode, executing codes corresponding to the LINE OUT mode, and controlling the left channel jack and the right channel jack to output signals of corresponding signal channels. In both the AV OUT mode and the LINE OUT mode, the sound volumes of the sound signals output from the left channel jack and the right channel jack are not adjustable, and therefore, the sound signals of the corresponding signal channels are output from the left channel jack and the right channel jack at a default fixed sound volume value.
The invention provides an extended use method of an AV OUT interface, which is characterized in that a signal output mode of the AV OUT interface is selected according to the occupation information of three jacks of the AV OUT interface, the signal output mode comprises an AV OUT mode and a LINE OUT mode, and corresponding codes are preset in the AV OUT mode and the LINE OUT mode. After one of the modes is selected as a signal output mode of the AV OUT interface, corresponding codes are executed, thereby controlling the video output jack, the left channel jack, and the right channel jack to output signals of a specified signal channel. The expanded use method of the AV OUT interface can enable the AV OUT interface to output signals of a plurality of signal channels, thereby enabling the AV OUT interface to realize the function of a LINE OUT interface, solving the problem of single function of the existing AV OUT interface, and being very simple and practical.
In this embodiment, when the signal output mode of the AV OUT interface is selected as the AV OUT mode, the step S4 of executing codes to control occupied video output jacks, left channel jacks and right channel jacks to output corresponding signals includes:
s41: judging whether the current signal channel is a TV or CVBS channel;
s42: if yes, controlling the video output jacks to output the picture signals of the current signal channel, and controlling the left channel jacks and the right channel jacks to output the sound signals of the current signal channel;
s43: if not, controlling the video output jack to output the picture signal of the TV channel, and controlling the left channel jack and the right channel jack to output the sound signal of the TV channel.
Therefore, in this embodiment, when the signal output mode of the AV OUT interface is selected as the AV OUT mode, the picture signals and the sound information of the TV or CVBS channel are always output by the AV OUT interface, and the original function of the AV OUT interface is realized.
Further, when the signal output mode of the AV OUT interface is selected as the LINE OUT mode, the step S4 of executing codes to control occupied video output jacks, left channel jacks, and right channel jacks to output corresponding signals includes:
s44: closing the picture signal output of the video output jack;
s45: and controlling the left channel jack and the right channel jack to output the sound signal of the current signal channel.
In this embodiment, when the signal output mode of the AV OUT interface is selected as the LINE OUT mode, the video output jack of the AV OUT interface does not output a signal, and the left channel jack and the right channel jack output a sound signal output by the current signal channel, so that the AV OUT interface realizes the function of the LINE OUT interface, can output a sound signal of each channel, and is not limited to outputting signals of a TV channel and a CVBS channel.
The extended use method of the AV OUT interface of this embodiment enables the AV OUT interface of the television to multiplex the function of the LINE OUT interface on the original function, and the function of the AV OUT interface is no longer single, so that the applicability is higher.
In particular, the signal channels include, but are not limited to, TV channels, CVBS channels, HDMI channels, and YPBPR channels. The signal channels may also include a VGA channel, a SCART channel, and a SVIDEO channel.
Further, in this embodiment, after step S4, executing the code to control the occupied video output jacks, left channel jacks and right channel jacks to output corresponding signals, the method further includes:
s5: receiving a command for switching to an earphone mode;
s6: judging whether the signal output mode of the current AV OUT interface is a LINE OUT mode or not;
s7: if yes, the signal output mode of the AV OUT interface is switched from the LINE OUT mode to the earphone mode, the output volume of the left channel jack and the right channel jack is reduced, and the sound output of the TV loudspeaker is turned off.
In this embodiment, the signal output mode of the AV OUT interface can be switched from the LINE OUT mode to the headphone mode, so that the AV OUT interface of the television can realize the function of the headphone interface in software. Specifically, the command for switching to the earphone mode is a UI _ EVENT _ SPEAKER command, and after receiving the command for switching to the earphone mode, the television determines whether the signal output mode of the current AV OUT interface is the LINE OUT mode, and if so, reduces the output volume of the left channel jack and the right channel jack and closes the sound output of the TV SPEAKER, so that the AV OUT interface outputs the sound signal of the current signal channel at the volume in the earphone mode. Further, in terms of hardware, since the specification of the AV OUT interface is inconsistent with the specification of the headphone interface, and the jack size of the headphone interface is smaller than that of the AV OUT interface, when the AV OUT interface is modified into the headphone interface, a patch cord needs to be used to plug the AV OUT interface, one end of the patch cord is a contact pin which is matched with the left channel jack and the right channel jack, and the other end of the patch cord is the headphone jack.
Further, if the signal output mode of the current AV OUT interface is not the LINE OUT mode but the AV OUT mode, the AV OUT interface is controlled to switch from the AV OUT mode to the LINE OUT mode, so that after the AV OUT interface outputs the sound signal of the current signal channel, the output volumes of the left channel jack and the right channel jack are reduced and the sound output of the TV speaker is turned off, and further the AV OUT interface is switched from the LINE OUT mode to the headphone mode.
Further, in the present embodiment, before step S5 of receiving a command to switch to the headphone mode, the method includes:
s5 a: monitoring whether a specified shortcut key is triggered or not;
s5 b: and if so, generating a command for switching to the earphone mode.
The embodiment generates and sends a command for switching to the headset mode by triggering the shortcut key, so that the AV OUT interface is switched from the LINE OUT mode to the headset mode. In other embodiments, the triggering may also be performed by inputting a password, which is not limited in the present invention.
Further, after step S7, it is also possible to switch the signal output mode of the AV OUT interface from the headphone mode to the LINE OUT mode by receiving a command to switch to the LINE OUT mode. Specifically, after receiving a command for switching to the LINE OUT mode, the television set determines whether the signal output mode of the current AV OUT interface is the headphone mode, and if so, increases the output volume of the left channel jack and the right channel jack and turns on the sound output of the TV speaker, so that the AV OUT interface outputs the sound signal of the current signal channel at the volume in the LINE OUT mode. In general, the output volume of the left channel jack and the right channel jack is set to the highest. In this embodiment, the command for switching to the LINE OUT mode and the command for switching to the headphone mode may be the same command, i.e., the UI _ EVENT _ SPEAKER command.
