While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
The embodiment of the present invention provides a method for acquiring an HDMI-CEC function of an electronic device, as shown in fig. 1, the method acquires a CEC main menu of the electronic device by one-key triggering, and for this, the following specific steps are provided in the embodiment of the present invention:
101. when a user operates the CEC shortcut key on the touch remote controller, a signal triggered correspondingly by the touch CEC shortcut key is received.
In the embodiment of the present invention, the electronic device is associated with a remote controller, and in the embodiment of the present invention, a CEC shortcut key needs to be set on the remote controller in advance, and the CEC shortcut key has the following functions: the user can call the CEC main menu on the side of the electronic equipment by operating and touching the shortcut key.
In an actual application scenario, when a user operates a CEC shortcut key on a touch remote controller, a signal is triggered accordingly, and the electronic device side receives the signal triggered by the remote controller.
102. And calling a CEC main menu from a client application of the electronic equipment by processing the signal, and displaying the CEC main menu, wherein the CEC main menu is used for configuring the HDMI-CEC function of the electronic equipment.
In the embodiment of the present invention, for the CEC shortcut key added to the remote controller, the electronic device side may also perform corresponding configuration in advance, for example, have a function of automatically calling out the CEC main menu by recognizing a signal triggered by the remote controller side.
For the embodiment of the present invention, the electronic device is equivalent to a terminal device having a client, for example, an intelligent television having an Android (Android) system, the client is an application program providing an intelligent application service, the provided intelligent application service includes setting an HDMI-CEC function (i.e., controlling other devices connected to an HDMI interface through a remote controller), so that the client provides a CEC main menu to a user for conveniently setting the HDMI-CEC function.
Further, the embodiment of the present invention exemplifies the HDMI-CEC bus communication diagram, as shown in fig. 2, including: the HDMI signal transmitting terminal and the HDMI signal receiving terminal; transition-minimized differential signaling (TMDS), also known as Transition-modulated differential signaling, TMDS channel 0/TMDS channel 1/TMDS channel 2 is used to transmit video and audio information; TMDS Clock Channel (TMDS Clock Channel); a Display Data Channel (DDC) Channel for acquiring extended Display Data enhanced by the HDMI signal receiving end, and acquiring device information or configuring the device information; the CEC bus, a universal control bus, is used for interconnection with HDMI devices.

For example, if the electronic device is in a standby state, a sleep state and a normal use state, the CEC main menu can be called from the client application of the electronic device by touching the CEC shortcut key on the remote controller with one key.
Moreover, according to the CEC shortcut key of the remote controller provided by the embodiment of the present invention, it can be determined whether the electronic device associated with the remote controller has the HDMI-CEC function.

Compared with the prior art, the technical problem that the operation steps of searching the CEC main menu on the electronic equipment are complicated, and the efficiency is low, so that the user experience is reduced is solved. The embodiment of the invention realizes that the CEC main menu of the electronic equipment is obtained by one-key triggering, thereby greatly efficiently and conveniently setting the subsequent HDMI-CEC function and improving the operation experience of obtaining the HDMI-CEC function by a user.

201. when a user operates the CEC shortcut key on the touch remote controller, a signal triggered correspondingly by the touch CEC shortcut key is received.
In the embodiment of the invention, when a user operates a CEC shortcut key on a touch remote controller, which is equivalent to triggering a key event, an electronic device associated with the remote controller receives a trigger signal. For example, if the remote controller is an infrared remote controller, the electronic equipment receives an infrared modulation pulse signal; in the case of a bluetooth remote control, the electronic device receives a radio signal.
202. And capturing message information corresponding to the key event by using the first processor according to the signal.
In the embodiment of the present invention, the first processor may be a Micro Controller Unit (MCU), and after receiving a signal triggered by a key event, the first processor captures message information corresponding to the key event, where the key event is an event triggered by a user operating a key on the touch remote controller.
In the embodiment of the invention, the message information at least comprises key values, key pressing information and key bouncing information. And judging whether the key operation corresponding to the key event is abnormal or not by identifying the key pressing information and the key bouncing information. For example, if it is recognized that the time of pressing a key is much longer than the time of bouncing the key, it may be predicted that a key is pressed but may not bounce.
Further, as shown in fig. 4, an embodiment of the present invention provides a simple flow chart of signal processing for an Android system electronic device, and the following steps 203 and 207 are explained with reference to fig. 4:
203. and transmitting the message information corresponding to the key event to the kernel of the second processor by using the first processor.
The second processor may be a processor using an ARM architecture, and the ARM architecture is a Reduced Instruction Set (RISC) processor architecture.
For the embodiment of the invention, the electronic device comprises a first processor and a second processor, wherein the first processor is equivalent to a slave processor, and the second processor is equivalent to a master processor in the working process of the electronic device.
For example, when the electronic device is in a normal use state, the second processor is used as a main processor to realize the corresponding control function; but the first processor implements the respective control function (e.g., mainly a low power consumption function) as a slave processor when the electronic device is in a sleep or unused standby state. And when the electronic device further needs to be woken up to enter a normal use state, the first processor receives the trigger signal and transmits the trigger signal to the second processor, for example, the communication between the MCU processor and the ARM core processor is utilized to complete a corresponding wake-up operation.
Further, for example, the first processor captures message information corresponding to the KEY event, and transmits the message information to the second processor, specifically, a KEY code driver module in a Kernel (Kernel) of the second processor reads the message information sent by the first processor, as shown in step (r) in fig. 4. And the step (c), (d) shown in FIG. 4 is a processing flow performed on the second processor side, and the following step 204 and 207 are explained.
204. Message information is passed to the hardware abstraction layer using key event actuation in the second processor core.
Among them, Hardware Abstraction Layer (HAL), interface Layer located between kernel of operating system and hardware circuit, its purpose is to abstract hardware, it hides hardware interface details of specific platform, provides virtual hardware platform for operating system, makes it have hardware independence, can be transplanted on various platforms.
In the embodiment of the present invention, the message information corresponding to the key event received by the second processor core is transmitted to the HAL layer, as shown in step two shown in fig. 4, specifically, the message information may be notified to the HAL layer in a socket cross-process communication manner. As shown in fig. 4, the Key processing module (Key _ code) implements related processing of message information in the HAL layer.
205. The message information is passed to the Java native method layer using the hardware abstraction layer.
For a Java Native method layer (KEYJNI), the layer provides C + + Native function service for implementing an interface for Java to call non-Java code, specifically: the Java native method layer is a communication layer planned in the Android system, and the HAL layer is C + + for code processing, so that the code processing is converted into Java processing by using the Java native method layer, so that the Java native method layer is suitable for the application program of the Android system. This step is shown in fig. 4.
206. The message information is passed to the Java application framework layer through the Java native method layer.
In the embodiment of the invention, a key processing manager (Phone Window manager) module in a framework layer of a Java application program receives message information transmitted by a Java native method layer. This step is shown as step (r) in fig. 4.
207. And processing the message in a Java application program framework layer, calling a CEC main menu from the client application and displaying the menu.
In the embodiment of the present invention, the step is represented as a step (c) shown in fig. 4, and the detailed explanation is as follows:
firstly, a key value corresponding to a key event is analyzed from message information, and an application identifier matched with the key value corresponding to the key event is determined by searching a preset mapping relation between the application identifier and the key value.
Secondly, calling a CEC main menu from the client application according to the matched application identification, and outputting and displaying the CEC main menu.
Wherein, the application identification means: identification of different smart application services provided by an electronic device client application. It is possible to know what the application service is provided according to the application identification, for example, calling up the CEC main menu from the current display screen.
It should be noted that, for different keys arranged on the remote controller, relevant configurations are pre-made on the electronic device associated with the remote controller, and the relevant configurations at least include: and pre-configuring a preset mapping relation between different application identifications and key values on the electronic equipment side. Therefore, according to the situation that different keys are pressed, different pictures are correspondingly shown by the electronic equipment to serve as feedback (namely, certain application service is called out), and then the operation control of the electronic equipment by using the remote controller is realized.
Accordingly, for the CEC shortcut keys added to the remote controller in the embodiment of the present invention, a preset mapping relationship between key values of the CEC shortcut keys and specific application identifiers is preconfigured on the electronic device side, and the specific application identifiers are used for referring to the provided application service for calling out the CEC main menu. Therefore, the method realizes that the CEC main menu is triggered and called out by one key through operating the CEC shortcut key on the remote controller so as to facilitate the subsequent related configuration of the HDMI-CEC functions on the CEC main menu.
