Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of data transmission, and in particular to a method for supporting dual-path services in an Android screen-equipped device, an Android screen-equipped device, an Android screen-equipped system, an electronic device and a storage medium. BACKGROUND

[0002] Currently, Android screen-equipped product forms include HDMI (High Definition Multimedia Interface)-CEC (Consumer Electronics Control) types.

[0003] CEC functions bring many conveniences to users. It allows end users to use one remote control to control multiple CEC-enabled devices, thereby eliminating the need to use multiple remote controls to control electronic devices such as televisions, set-top boxes, projectors, etc. However, only one of the configurations, playback (display device) or TV (television), is usually supported.

[0004] If information such as images is transmitted from a set-top box to an Android screen-equipped product, in order to achieve remote control of the set-top box by the Android screen-equipped product, the Android screen-equipped product needs to be configured as a TV product form. If information such as images is transmitted from an Android screen-equipped product to a projector, in order to achieve remote control of the Android screen-equipped product by the projector, the Android screen-equipped product needs to be configured as a playback product form. In the prior art, different HDMI channels need to be selected to achieve the conversion between different product forms, so flexible switching cannot be achieved. SUMMARY

[0047] Figure 2 This is a block diagram illustrating an Android device with a screen 200 according to an embodiment of the present invention. (Refer to...) Figure 2 This includes a first HDMI-CEC module 202 and a second HDMI-CEC module 204. It simultaneously supports HDMI IN / OUT. For Android devices with screens 200, in dual-channel scenarios, one service manages the HDMI CEC device link for the HDMI IN interface, and another service manages the HDMI CEC device link for the HDMI OUT interface. The first and second services then coordinate and interact with other relevant services in the system.

[0048] According to another aspect of the present invention, this disclosure provides an Android system with a screen. The system includes multiple sets of the aforementioned Android devices with screens; along a data transmission path, a first HDMI-CEC module of the Android device with screen is configured to connect to a second HDMI-CEC module of an Android device with screen at the next higher level in the transmission path, and the second HDMI-CEC module of the Android device with screen is configured to connect to the first HDMI-CEC module of an Android device with screen at the next lower level in the transmission path.

[0049] In some embodiments, Figure 3 This is an application connection diagram illustrating an Android device with a screen 300 according to an embodiment of the present invention. (Refer to...) Figure 3 The first HDMI-CEC module 302 is configured to connect to the set-top box device 306 (Box). The second HDMI-CEC module 304 is configured to connect to a large-screen device such as a projector 308. That is, relative to the set-top box device 306, the screen-equipped device 300 is a playback product type; relative to the projector 308, the screen-equipped device 300 is a TV product type. This allows the screen-equipped device 300 to control the Android screen-equipped device 300 during interaction with the projector 308, provided both the first HDMI-CEC module 302 and the second HDMI-CEC module 304 are connected. Furthermore, the screen-equipped device 300 can control the set-top box device 306 during interaction. Simultaneously, when the Android screen-equipped device 300 is displaying content from the set-top box device 306, interaction with the projector 308 can also control the set-top box device 306.

[0050] In specific application scenarios, both the Android device with a screen 300 and the projector 308 display the content output by the Box. In this case, for example, when the remote control or touchscreen of the Android device with a screen 300 performs operations supported by HDMI CEC (see the CEC Table 30ul Command Codes section of the HDMI Specification 1_4b), the system of the set-top box device 306 is being operated. For interactive operations such as those using the projector 308 remote control, the events are first transmitted to the Android device with a screen 300. When the Android device with a screen 300 is connected to the HDMI CEC set-top box device 306, it can then transmit the input events to the system of the set-top box device 306.

[0051] In another specific interactive application scenario, the specific interaction process is as follows. Other system services include power management services, sound management services, and event input services;Figure 3 In System Standby mode, for example:

[0052] S1, HDMI CEC TV / PLAYBACK service registers a listener to receive standby messages upon startup;

[0053] S2. When the connected Projector device is in standby mode, the Projector device broadcasts an HDMI-CEC standby message in the second HDMI-CEC module path.

[0054] When the S3 and HDMI CEC PLAYBACK services receive a standby message from the connected Projector device, they call the system power management service to enter the standby process.

[0055] S4, System power management service broadcasts standby messages;

[0056] The S5 HDMI CEC TV service registered listener receives the standby broadcast message from the power management service and broadcasts the HDMI-CEC standby message through the first HDMI-CEC module;

[0057] S6. The Box device connected to the system's HDMI CEC TV path receives the HDMI-CEC standby message and enters standby mode.

[0058] In some embodiments, Figure 4 This is another application connection diagram illustrating an Android device 400 with a screen according to an embodiment of the present invention. (Refer to...) Figure 4 Along the data transmission path, the first HDMI-CEC module 406 of the Android device with a screen (N) is configured to connect to the second HDMI-CEC module 404 of the Android device with a screen (N-1) at the next level in the transmission path; the second HDMI-CEC module 408 of the Android device with a screen (N) is configured to connect to the first HDMI-CEC module 410 of the Android device with a screen (N+1) at the next level in the transmission path. That is, when multiple devices with screens are connected, it can support interactive control functions between the Android device with a screen (N) and the Android device with a screen (N-1). Specifically, for the Android device (N), the previous Android device (N-1) is the playback device, while the Android device (N) is the TV; for the Android device (N+1), the Android device (N) is the playback device, and the Android device (N+1) is the TV.

[0059] According to another aspect of the invention, Figure 5This is a schematic diagram illustrating an electronic device 400 according to an embodiment of the present invention. (Refer to...) Figure 5 The electronic device 500 includes a memory 502, a processor 504, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it implements the steps of the dual-channel support method for a screen-equipped device as described above.

[0060] According to another aspect of the present invention, a computer-readable medium is provided. The computer-readable medium stores a computer program that is executed by a processor to implement the dual-channel support method for a screened device as described above.

[0061] In summary, the present invention provides a method, an Android device with a screen, a system, an electronic device, and a storage medium for supporting dual-channel services in an Android device with a screen. The first service, via a first HDMI interface, enables the reception of first display information and the display of first content, as well as the transmission of first CEC information for controlling the first content. The second service, via a second HDMI interface, enables the transmission of second display information and the reception of second CEC information, and the control of the second display information. Therefore, it can be applied to dual-channel service scenarios with HDMI input and output.
