Description

Startup interface control method and display device

Technical Field

The invention relates to the field of display equipment, in particular to a startup interface control method and display equipment.

Background

In some application scenarios, the display device may be connected to an external device, such as a DVD device, a set-top box, etc., through an HDMI (High Definition Multimedia Interface), if the external device has a CEC (Consumer Electronics control) control function enabled, when a user starts a certain external device, the external device becomes an Active Source, and the Active Source sends a CEC signal to the display device through the HDMI, so that the display device is automatically turned on after receiving a notification of the CEC signal, and the turn-on mode is no longer limited to triggering a turn-on key on the local device or the remote controller.

For example, the external device is a DVD, the display device is waken up to be started up by starting the DVD, if the display device is installed in an android system, the display device is limited by a native architecture of the android system, the display device cannot acquire a CEC message broadcasted by the DVD in the starting process, and a signal channel parameter of the DVD cannot be analyzed from the CEC message, so that the TV is generally set as an Active Source by default when the android system is started up, and the display device can only display a homepage interface after being started up, but cannot display a DVD playing interface desired by a user.

Disclosure of Invention

The invention provides a startup interface control method and display equipment, which can automatically identify the startup reason and acquire the current Active Source when the display equipment is started, thereby adaptively switching signal channels and correspondingly controlling the display of a startup interface.

A first aspect provides a display device comprising:

the display is used for displaying a starting interface;

HDMI for connecting external device;

a controller configured to perform:

after receiving a starting-up instruction, acquiring a driving source for controlling the display equipment to start up;

when the driving source is detected to be HDMI, sending a target device acquisition request to external devices, wherein the target device acquisition request is used for requesting to acquire a target device which is in an active state currently in the external devices;

when response information sent by the target equipment is received, switching a video channel to a signal channel matched with the response information;

and after the display equipment is started, controlling the display to display a starting interface according to the data output by the video channel.

and after the display equipment is started, displaying a starting interface according to the data output by the video channel.

According to the method and the device, on the basis of the native architecture of the android system, in a display device starting program, a signal channel is accurately determined according to the type of a driving Source and the current Active Source, so that the display device can display a starting interface corresponding to the current real signal channel. The driving source is a source acquired from a driving layer and used for instructing to wake up the startup of the android system, that is, the driving source is used for instructing a startup reason, for example, when the driving source is HDMI, the startup reason is that the external device synchronously controls the television to be started based on CEC, and when the driving source is not HDMI, the startup reason may be that a user presses a power key on a remote controller, or the user presses a power key on the television, or the like. When the driving Source is detected to be the HDMI, the target device needs to send an acquisition Request, that is, a Request Active Source is executed, so as to Request an external device, that is, the target device (Active Source), on the CEC bus, which is currently in an Active state, the Active Source feeds back response information after responding to the Request, the response information generally carries parameters related to a signal channel of the Active Source, such as a port number of the HDMI, and the display device automatically switches the video channel to a signal channel matched with the response information, so that after the display device is started, a native startup interface is displayed according to video data output by the Active Source signal channel, and no longer, as in an android system architecture, a home page interface is displayed regardless of a startup reason and the Active Source, so that the display of the startup interface is more consistent with the user expectation, and the startup time of the android system is not increased.

The above embodiments describe the hardware/software architecture and functional implementation of the display device. In some application scenarios, a plurality of HDMI interfaces are generally preset on the display device, and the display device can be connected with external devices through the HDMI interfaces, where the external devices include video signal source devices such as DVD devices and set-top boxes, and video signals of the external devices are transmitted to the android system through the HDMI, and the system controller controls the display device to display the video signals. For example, if the external device is a DVD, if the DVD has the CEC control function enabled, when the user starts the DVD, the DVD sends a CEC wakeup signal to the display device through the HDMI, so that the display device is automatically turned on after receiving the notification of the CEC wakeup signal, and waking up the display device through the external device to automatically turn on is an important link in the CEC control function.

In some embodiments, fig. 5 shows an execution logic of a start-up program in a native architecture of an android system, and when the display device is in a standby state, if a CEC wake-up signal transmitted by an HDMI is received, or a user clicks a power key of a remote controller, or a local on-off key is received, that is, a start-up instruction is received, the android system is started. After an Android (Android) System is started, firstly, a System Service is started, a CEC related Service program built in the Android System, namely an HDMI Control Service is loaded, and then a starting interface OnStart of the HDMI Control Service is called to be responsible for allocating a logic address; after the logical address allocation is completed, a launch routing control interface is called, a factor (namely, a startup reason) for triggering a startup instruction is not obtained from an android system native code, and an Active Source in an Active state on a CEC bus is not obtained, but the launch routing control interface is used for directly setting a TV as the Active Source by default, after loading of other subsequent system modules is completed, the display device inquires that the current Active Source is the TV, and because a startup interface corresponding to the TV is a homepage (Launcher) interface, the startup interface displayed after the display device is started is a preset homepage interface.

Therefore, the native architecture of the android system does not consider that the display of the startup interface is controlled according to the startup reason of the display device and the current actual Active Source, but automatically defaults the Active Source to be a TV, so that the startup interface is unified into a homepage, and if a user starts a DVD to wake up the television to start, the user more expects the relevant interface of the DVD to be displayed after the television is started, so that the android television cannot provide better CEC service for the user.

Referring to the HDMI-CEC technology, a display device (i.e., a root device) and at least one external device are connected to a CEC bus, query and communication between devices are controlled through the CEC bus, only 1 external device is generally in an Active state on the CEC bus, and the external device is the current Active Source, and after the display device sends a Request Active Source, the Active Source receives the Request and then gives a response, and the display device can obtain the Active Source. In order to solve the problem and defect existing in the native architecture of the android system, the method and the device have the advantages that the boot reason and the information acquisition program of the Active Source are additionally arranged at the boot stage of the display device, the signal channel corresponding to the actual Active Source is adaptively matched through the combination of the two items of information, the video channel is switched to the corresponding signal channel, the signal output of the video channel is changed, the display of the boot interface is adjusted, the boot interface is more in line with the expectation of a user, and the application experience of the user is improved.

In some embodiments, fig. 6 illustrates a power-on interface control method, the execution subject of the method is a controller 250 of a display device, the method includes the following program steps:

in step S10, after receiving the power-on command, a driving source for controlling the power-on of the display device is obtained.

The driving source is a transmission source of the power-on command, for example, if the external device sends a CEC wake-up command to the display device through the HDMI, the driving source is the HDMI; if the user sends a starting-up instruction to the display equipment by pressing a power key of the remote controller, the driving source is the remote controller; if the user inputs a power-on instruction by pressing a power-on key of the display device, the driving source is the power-on key of the display device. The driving source of the power-on instruction input by the remote controller, the power-on key of the display device and the like belongs to non-HDMI.

In step S20, it is detected whether the drive source is HDMI. If the driving source is HDMI, executing the step S30-S50; on the contrary, if the drive source is non-HDMI, step S60 is executed.

Step S30, the target device acquisition request is sent to the external device. The target device obtaining Request is used for requesting to obtain a target device which is in an Active state currently in the external devices, wherein the target device obtaining Request is a Request Active Source, and the target device is an Active Source which is in an Active state currently on the CEC bus.

And step S40, when the response information sent by the target device is received, the video channel is switched to the signal channel matched with the response information.

In some embodiments, the acknowledgement information includes a physical address of the Active Source device, such as a port parameter of the HDMI to which the Active Source is connected. For example, after the Active Source responds to the Request Active Source, the feedback response information is < Active Source > BF:0x82:30:00, wherein the < Active Source > information is generated by triggering of the Request Active Source, B represents a logical address of the Active Source, F represents broadcasting, 0x82 represents an Opcode, and 30:00 represents a port number of an HDMI to which the Active Source device is connected, indicating that the Active Source is connected to an HDMI3 interface.

In some embodiments, the underlying Source management module registers the inputchangelist to the CEC module at the boot stage of the display device, the CEC module calls the invokeinputchangelist interface when subsequently receiving the response message < Active Source >, the port number carried in the response message is used as a parameter and is transmitted to the Source management module, and the Source management module completes the switching of the video channel Source, so as to switch to the signal channel of the device connected to the HDMI corresponding to the port parameter, after the signal channel is switched, the data of the channel data is changed, and the boot interface displayed after the display device is booted is not the home interface, but the video signal output by the Active Source signal Source.

And step S50, after the display device is started, controlling the display to display a starting interface according to the data output by the video channel.

Because the Source switching of the video channel is completed in the step S40, and the video channel is tuned to the signal channel of the Active Source, the output data is the video signal from the current actual Active Source, the booting interface is no longer the homepage, and the booting interface can be accurately matched with the external Active Source, thereby improving the display accuracy of the booting interface.

And step S60, setting the target device as the display device local machine, not switching the video channel, keeping the video channel as the TV channel, and controlling the display to display the homepage interface after the display device is started.

In step S60, when the driving Source is not HDMI, it indicates that the factor triggering the display device to power on is not a CEC wake-up signal sent by the external device, so that the Active Source does not need to be recognized from the external device, but the display device local (i.e., TV) is directly set as the Active Source, and a preset home interface is displayed after the display device is powered on.

In some embodiments, after receiving the Request Active Source, the Active Source generally returns a response message within a predetermined time, such as 2 seconds. And after the display equipment sends the Request Active Source, starting a timer to monitor the timing of the response information, wherein the time set by the timer is the preset time, and if the display equipment receives the response information within the preset time, analyzing the response information and switching a Source channel according to the parameters carried in the response information. The preset time can be specifically set according to practical application, and the application is not limited.

In some embodiments, if the display device does not receive the response information within the preset time, it is considered that the response is overtime, a retry mechanism may be started, that is, Request Active Source is sent again, the number of retransmissions needs to be counted and recorded under the retry mechanism, every time the Request Active Source is sent again, the number of retransmissions is cumulatively added by 1, and it is detected whether the number of retransmissions exceeds a threshold, for example, 2 times, if the number of retransmissions is less than or equal to the threshold, the loop retry is allowed to continue, but if the number of retransmissions exceeds an upper limit of the threshold, the display device still does not receive the response information, it is considered that there is no Active Source in the current external device, the execution of the retry mechanism needs to be forcibly terminated, and step S60 is executed, the TV local machine is set to be Active Source, the Source channel is not switched, and the display device displays a home page interface after being turned on. By means of the retry mechanism, missing of receiving response information in case of response timeout is avoided, and by means of threshold value constraint when retry, repeated execution of invalid retry procedure can also be avoided. The threshold may be set according to practical applications, and the application is not limited.

In some embodiments, the display device receives the message within the preset time, but the message may not be response information, but may be feature abort information, for example, when the Active Source cannot immediately process the Request Active Source, or an abnormal condition such as an error occurs in the layer data of the higher-level protocol in the information transmission process, the Active Source returns the feature abort to the display device; if the display device receives the feature abort within the preset time, step S60 is executed, the TV native is set to Active Source, the Source channel is not switched, and the display device displays the homepage interface after being turned on.

The foregoing embodiments are control logic provided from the perspective of a display device system controller. In some embodiments, fig. 7 shows the execution logic of a boot program after android architecture is improved, and a more detailed underlying control program is executed in a controller as follows:

when the display device receives a starting instruction, an android System and a System Service are started in sequence, then a driving Source is obtained from a driving (driver) layer, a starting attribute field of the android System is set and stored according to the driving Source, the starting attribute field is configured into a format of sys.

When the System Service is started, the HDMI Control Service is loaded, an OnStart interface is called, and the OnStart interface is responsible for distributing a logic address; after the logical address allocation is completed, a launch routing control (route mapping control) interface is called, and the launch routing control reads the replay value in the startup attribute field, so that the type of the driving source is identified, the startup reason is obtained, and whether the driving source is the HDMI or not is judged.

If the driving Source is not HDMI, the LaunchRouteingControl sets the TV to be the current Active Source, keeps the video channel as the default TV channel, does not switch to the signal channel of the external device any more, and displays the preset home page interface after the display device is started.

If the driving Source is HDMI, it indicates that the external device connected to the display device through the HDMI wakes up the android system to start automatically, the CEC module sends a Request Active Source to Request a target device currently in an Active state on the CEC bus, and the target device in the Active state responds to the Active Source after receiving the Request, and the CEC module needs to detect whether information fed back by the Active Source is received within a preset time.

If the CEC module does not receive the information fed back by the Active Source within the preset time, triggering a retry mechanism, resending the Request Active Source, updating the recorded retransmission times, and judging whether the retransmission times exceed the threshold value. If the retransmission times do not exceed the threshold value, the cycle retry is allowed, until the response information is received within the preset time after a certain request, the execution retry mechanism is terminated, the CEC module analyzes the response information and transmits the HDMI port parameters carried in the response information to the Source management module, the Source management module switches the Source to the signal channel of the HDMI connected equipment corresponding to the port parameters, and the startup interface displayed after the display equipment is started is not the homepage interface any more, but the video signal output by the Active Source signal Source.

If the retransmission times exceed the threshold value and the CEC module still does not receive the response information, the execution retry mechanism is terminated, the LanunchRoutetingControl sets the TV as the current Active Source, the video channel is kept as the default TV channel, the switching to the signal channel of the external device is not performed, and then the display device displays the preset home page interface after the startup is completed.

If the CEC module receives information fed back by the Active Source within the preset time, whether the information is response information is detected, if the information is the response information, the CEC module analyzes the response information and transmits HDMI port parameters carried in the response information to the Source management module, the Source management module switches the Source to a signal channel of equipment connected with the HDMI corresponding to the port parameters, and a starting interface displayed after the display equipment is started is not a homepage interface any more but a video signal output by an Active Source signal Source.

If the CEC module receives not the response information but the feature abort in the preset time, the LaunchRoutengControl sets the TV as the current Active Source, keeps the video channel as the default TV channel, and does not switch to the signal channel of the external device any more, and then the display device displays the preset homepage interface after the startup is completed.

On the basis of a native architecture of the android System, a slave driver layer is additionally arranged after System Service is started to inquire a starting reason, a starting attribute field of the android System is set and stored, a replay value in the starting attribute field is read after a route mapping control interface is called, and adaptive control logic is executed according to the replay value and a response condition received after a Request Active Source is sent, so that a starting interface meeting user expectation is displayed after the starting of display equipment is completed, the starting time of the android System cannot be increased, and the user experience is improved.
