S801. Obtain device information of at least one access device.

The device information includes at least one of the following: device name, device type identification, priority, and user name.

In some embodiments, at least one HDMI interface in the display device obtains device information of at least one access device. As shown in Figure 4, the display device 200 obtains the device information of the DVD player 501 through the HDMI1 interface, the display device 200 obtains the device information of the set-top box 502 through the HDMI2 interface, and also obtains the device information of the audio 503 through the HDMI3 interface.

Exemplarily, the display device receives device information of at least one access device as shown in Table 1.

Table 1

As shown in Table 1 and Figure 4 above, the display device 200 obtains the device information of the access device DVD player 501 through the HDMI1 interface. The device information of the DVD player 501 includes the device name DVD player, device type identifier CEC, and priority. 1; The display device obtains the device information of the set-top box 502 through the HDMI2 interface. The device information of the set-top box 502 includes the user name Xiao A. The display device obtains the device information of the audio 503 through the HDMI3 interface. The device information of the audio 503 includes the device name. 5282871055, user name audio, where the device name 5282871055 can be understood as the audio 503 sends the identification number (Identity Document, ID) as the device name to the display device 200.

It should be noted that CEC refers to consumer electronics control equipment, which refers to equipment that supports consumer electronics control functions. Consumer Electronics Control (CEC) allows display devices to use one control device (for example, a remote control) to control multiple supported devices. CEC-enabled devices. CEC devices such as DVD and Chromecast.

S802. Determine an indication identifier of at least one access device based on the device information of at least one access device.

Wherein, the indication mark is the mark of at least one access device that is finally displayed in the user interface of the display device, and is used to distinguish each access device. The user can accurately distinguish different access devices according to the indication mark.

In some embodiments, the device name included in the obtained device information of at least one access device is used to determine the indication identifier of at least one access device based on the device name. For example, refer to the device name of at least one access device shown in Table 1. Information, according to the device name DVD player, it is determined that the indication mark of the device connected through the HDMI1 interface is a DVD player.

It should be noted that due to the particularity of its functions, the CEC device will directly set the device name before leaving the factory, making it simple, concise and easy for users to understand. Therefore, the embodiment of the present application provides an implementation method to determine the CEC device in at least one access device, and use the device name of the CEC device as an indication identifier. Specifically, first, according to the obtained device information of at least one access device, the device information of each access device is traversed, and the target device type identifier is determined based on the device type identifier of each access device. The target device type identifier is used to indicate the target. The access device corresponding to the device type identifier is a CEC device, that is, the target device type identifier is CEC. When it is determined that the target device type identifier exists, determine the access device corresponding to the target device type identifier CEC, and use the device name included in the device information of the access device as the indication identifier of the access device for display .

Exemplarily, the device information of at least one access device obtained by the display device is as shown in Table 1. After traversing each access device, the CEC device—DVD player—is determined from at least one access device according to the device type identifier CEC. , and then use the device name of the CEC device DVD player: DVD player as the indicator of the access device DVD player.

In the above embodiment, the target device type identifier CEC is determined from at least one access device through the device type identifier included in the device information sent by the access device, so that the simple and concise device name of the CEC device is used as the indication identifier corresponding to the CEC device. , to facilitate users’ understanding and identification.

In some embodiments, the obtained device information of at least one access device includes a user name. First determine whether the access device is a CEC device. When the access device is not a CEC device and the device information includes a user name, the user name of the access device is used as the indicator of the access device. For example, refer to Table 1. The access device corresponding to the HDMI3 interface is not a CEC device. device, but the device information of the access device includes the user name "Audio", then the user name "Audio" is used as the indicator of the access device corresponding to the HDMI3 interface.

In some embodiments, when the device information does not include the device name or user name, the channel name of the HDMI interface is used as an indicator of the access device to avoid the situation where the access device is connected to the HDMI interface but no display is performed. . For example, if the display device is connected to device S through the HDMI4 interface, and the device information sent by device S to the display device through the HDMI4 interface does not include the device name and user name, then "HDMI4" will be used as the indicator of device S.

In some embodiments, after obtaining the device information of at least one access device, the target HDMI interface is determined from at least one HDMI interface. There is a target name corresponding to the target HDMI interface to distinguish it from other HDMI interfaces. For example, the target HDMI interface supports audio. Audio Return Channel (ARC) function, the target name corresponding to the target HDMI interface is ARC. Among them, the main function of audio return is to transmit sound signals. On the HDMI interface that supports ARC, the display device can use ARC to transmit the audio signal back to the power amplifier or other audio equipment that supports the ARC function through the HDMI cable. In this way, No additional digital output cables are needed anymore.

Further, an indication identifier of at least one access device is determined according to the device information of the access device and the target name. For ease of understanding, here the indication mark determined based on the access device information is first noted as the to-be-displayed mark. After the identification to be displayed is determined based on the access device information, the target name is added to the identification to be displayed as an indication identification to instruct the access device to access the display device through the HDMI interface that supports the ARC function.

For example, the HDMI3 interface supports the ARC function. Following the above example, when it is determined that the indicator mark of the access device corresponding to HDMI3 is "sound", add the name "ARC", which is the final indicator mark of the access device corresponding to HDMI3. for "Audio (ARC)". It should be noted that the way of adding the ARC identifier is only exemplary. For example, the way of adding the "ARC" name can also be "-ARC", and the position of adding the "ARC" name can also be after the parent name. Here, for adding There are no specific restrictions on the position and method of the "ARC" name, and will not be described in detail here in this application.

TIF is mainly used to create TvInput modules To control TVs with Android systems and provide management of system signal sources, the corresponding system service is TvInputManagerService (TV input management service). HDMITvInputService (High Definition Multimedia Interface TV Input Management Service) is a signal control service provided by TV manufacturers to control HDMI channels. It can provide identification, registration, creation, control and destruction of HDMI channels. It starts running after the TV system starts. The operating system of the display device may be an Android system.

Correspondingly, after the access device is connected to the display device, the display device automatically turns on the CEC Control function by default. If the CEC function is not turned on, you can set CEC Control to on and TV auto power on in Settings. open. At the same time, the access device is connected to the display device through an HDMI cable. When TV auto power on is set to on, HDMI is connected to the signal source (access device, such as DVD), and the signal source and display device are turned off. When the signal source is turned on, the display device automatically turns on and switches to HDMI aisle.

Therefore, when the processor of the display device detects the access device, it can determine the HDMI channel accessed by the access device through the TIF provided by the operating system of the display device, and directly set the channel of the display device to the HDMI channel accessed by the access device. HDMI channel.

In this example, the channels of the display device are set through the above channel setting method, which is efficient and fast, and is conducive to the smooth progress of the subsequent process.

In some embodiments, the physical channels of the display device in the TIF may include Tuner (Tv channel, that is, the channel to which the signal lines of the display device are connected), HDMI channel, and Composite channel (AV channel, that is, the channel to which the yellow, white, and red lines are connected). channel), etc. Each channel corresponds to a unique string inputId (input identification), which serves as the unique identification of the channel. Among them, the HDMI channel is quite special. When an access device (such as DVD, box, etc.) is inserted into the HDMI port, the access device will be added to the channel list as a sub-channel (i.e., access device name, CEC Name), and After the access device is plugged into the HDMI port, the Android system will receive a notification from the underlying hardware, and the access device will be automatically added to the channel list. At the same time, the sub-channel will also disappear after the access device is unplugged to avoid being displayed all the time.
