Description
Technical Field
The present invention relates to the field of Internet Protocol Television (IPTV), and more particularly, to a system and method for automatically switching between a remote controller mode and a mouse mode based on a scene.
Background
In the field of mobile devices, smart tv set-top boxes of IPTV have gradually entered people's daily life to replace traditional digital tv set-top boxes.
The input module of the smart television set top box is a core module for interaction between a user and an IPTV, and the use experience of the input module directly influences the experience of the user. In the existing IPTV system based on the android platform, the interaction mode with the user is mainly remote controller, but the APP which needs to be installed supports the remote controller mode, and for the part of APPs which do not support the remote controller mode, the operation can be carried out by using a mouse or a touch mode. There are roughly two existing solutions to this problem.
The first solution is to provide a remote control button or trigger in another way for the user, and when the user finds that the remote control cannot operate the APP, the user presses the button or activates the trigger, and switches the remote control input mode of the remote control buttons to the mouse input mode, so that the user can continue normal use. Although the problem of the APP which does not support the remote controller can be solved in the mode, sometimes great trouble is brought to the user, the problem that the user does not respond to the remote controller as a system probably because the user does not know the existence of the mode, and although the problem can be solved in a consultation mode, the user experience is influenced to a great extent.
The second solution is to add a touch panel on the infrared remote controller to support click touch, so that the remote controller has two input functions of a mouse mode and an infrared remote controller mode, and further the problem that the remote controller mode APP operation is not supported is solved. However, the method needs to add a touch panel and a chip on the remote controller, which undoubtedly increases the manufacturing cost of the product, and for the set-top box of the IPTV, the price is already relatively low, and the sensitivity to the price is also relatively high, so that the problem of the APP operation that does not support the remote controller mode can be solved by using a mode that does not increase the equipment cost, and the overall competitiveness of the product is undoubtedly improved.

Detailed Description
The preferred embodiments of the present invention will be described below with reference to the accompanying drawings, and it should be understood that the preferred embodiments described herein are merely for the purpose of illustrating and explaining the present invention and are not intended to limit the present invention.
The invention provides a system for automatically switching a remote controller mode and a mouse mode based on a scene, which is based on a code flow running on an android platform, an infrared remote controller and a driver supporting the infrared remote controller, wherein the driver supporting the infrared remote controller is adapted to the android system and can enable the system to detect a key signal of the infrared remote controller.
Fig. 1 is a schematic diagram of a system for automatically switching a remote controller mode and a mouse mode based on a scene according to the present invention, and as shown in fig. 1, the system for automatically switching a remote controller mode and a mouse mode based on a scene according to the present invention includes a first call module 110, a second call module 120, a third call module 130, a fourth call module 140, and a fifth call module 150.
The first calling module 110 is a kernel infrared driver module, and can obtain and identify a key operated by a user when using a remote controller, and report a key value of the remote controller to the android system.
The second calling module 120 is a module (InputDispatcher) for distributing events in a local library module (libinputservervice) in the android input subsystem, and acquires a key value corresponding to the remote controller reported by the first calling module 110 and sends the key value to the APP of the current interface; meanwhile, the second calling module 120 receives feedback information that the infrared key value sent by the APP is processed and sends the feedback information to the third calling module 130.
The third invoking module 130 sends a feedback processing module for the key value added in the local library, and determines whether the input mode needs to be switched according to the feedback information obtained from the second invoking module 120.
The fourth calling module 140 is a system calling module for switching between the infrared remote controller mode and the mouse mode, and switches between the remote controller mode and the mouse mode based on the determination result of the third calling module 130.
The fifth calling module 150 is a module that converts the received specific key of the remote controller into a mouse event report in the infrared driver and shields the report of other remote controller events. Specifically, if the key value received by the fifth calling module 150 is a specific key (e.g., up, down, left, right, OK, or return key) of the remote controller, the specific key is converted into a corresponding mouse event in the driving, optionally, for example: converting the up key to an up shift unit of the mouse event; converting the down key into a unit for moving down the mouse event; converting the left button to a left shift by one unit of a mouse event; converting the right button into a mouse event and moving the mouse event to the right by one unit; converting the OK key into a left key of a mouse event; converting the return key to a right key of the mouse event; and reports to the upper layer through the reporting interface corresponding to the mouse event. If the fifth calling module 150 receives the key value of the remote controller other than the specific key, the reporting process is not performed.
Based on the system 10 for automatically switching the remote controller mode and the mouse mode based on the scene in the above embodiment, an embodiment of the present invention provides a method for automatically switching the remote controller mode and the mouse mode based on the scene, which includes a process of automatically switching from the remote controller mode to the mouse mode and a process of automatically switching from the mouse mode to the remote controller mode. Fig. 2 is a schematic flow chart of switching from the remote controller mode to the mouse mode according to the present invention, and the following describes in detail the switching from the remote controller mode to the mouse mode according to the present invention with reference to fig. 2:
first, in step S101: and reporting the key value of the remote controller.
In this step, the kernel infrared driver module, i.e. the first calling module 110, acquires and identifies the operated keys of the remote controller and reports them to the android system, i.e. the user uses the infrared remote controller to operate any key thereof, e.g. press any key of the up, down, left, right, and OK keys of the remote controller, and the first calling module 110 in the android system acquires and identifies the corresponding key value and reports it to the android system.
Step S102: and sending the key value to the APP for processing and receiving a feedback key processing result.
In this step, the second calling module 120 obtains the key value reported by the first calling module 110 and sends the key value to the APP on the current interface, and meanwhile, the second calling module 120 receives feedback result information that the infrared key value sent by the APP is processed.
Step S103: judging whether the key is normally processed; if the processing is normal, the processing proceeds to step S107; if not, the process proceeds to step S104.
In this step, the third invoking module 130 determines whether the input mode needs to be switched according to the feedback result information from the second invoking module 120, that is, the third invoking module 130 determines whether the remote control key is normally processed based on the feedback result information obtained by the second invoking module 120.
Step S104: and saving the currently registered window packet name, and marking that the window does not support the remote controller.
Step S105: and calling an ioctl interface provided by the kernel to switch the remote controller mode into a mouse mode and marking the remote controller mode as the mouse mode in the local library.
The fourth calling module 140 calls an ioctl interface provided by the kernel to switch the remote controller mode to the mouse mode, and meanwhile, the remote controller mode is marked as the mouse mode in the local library.
Step S106: and converting the received specific key value into a mouse event to be reported, and shielding other remote controller events.
The fifth calling module 150 calls the kernel, converts the received specific key of the remote controller into a mouse event report and shields other remote controller event reports. Specifically, the kernel turns on a switch supporting a mouse mode in the infrared drive, and if the received key value of the remote controller is an up, down, left, right, OK or return key, the fifth calling module 150 converts the key value into a corresponding mouse event in the drive, for example, the up key may be converted into an upward movement unit of the mouse event; converting the down key into a unit for moving down the mouse event; converting the left button to a left shift by one unit of a mouse event; converting the right button into a mouse event and moving the mouse event to the right by one unit; converting the OK key into a left key of a mouse event; converting the return key to a right key of the mouse event; meanwhile, the fifth calling module 150 reports the mouse event to the upper layer through the reporting interface corresponding to the mouse event. If other key values of the remote controller are received, the report is not carried out.
Step S107: and processing according to the normal flow of the remote controller mode by default.
In step S103, if the key of the remote controller is normally processed, the normal flow processing is performed by default in the remote controller mode, and at this time, the switching from the remote controller mode to the mouse mode is not required.
The steps realize the automatic switching from the remote controller mode to the mouse mode, and at the moment, if a user or a system opens an APP supporting the remote controller, the mouse mode needs to be automatically switched back to the remote controller mode.
Fig. 3 is a schematic flow chart of switching from a mouse mode to a remote controller mode according to the present invention, and the following describes in detail the flow chart of switching from the mouse mode to the remote controller mode according to the present invention with reference to fig. 3:
step S201: and reporting the received specific key value in the mouse mode.
In the mouse mode, the second calling module 120 obtains the mouse event reported by the first calling module 110.
Step S202: events are dispatched to the registered windows in the local library's interface.
Step S203: judging whether the registered window packet name is the same as the stored window packet name needing to switch the mouse mode or not; if the two are the same, go to step S205; if not, go to step S204.
And calling a third calling module 130 in the local library, namely a feedback processing module in the local library, and comparing the stored window packet names which do not support the remote controller window with the window packet names of the mouse event distribution object APP one by one.
Step S204: and calling an ioctl interface provided by the kernel to switch to a remote controller mode and marking the ioctl interface as the remote controller mode in the local library.
In step S203, if the registered window packet name is not the same as the stored window packet name that needs to switch the mouse mode, the fourth calling module 140 calls the ioctl interface provided by the kernel to switch the mouse mode to the remote controller mode, and meanwhile, marks the mouse mode as the remote controller mode in the local library.
Step S205: the mouse mode continues.
In step S203, if the registered window packet name is the same as the stored window packet name for which the mouse mode needs to be switched, the mouse mode does not need to be switched to the remote controller mode, and at this time, the process of simulating the mouse mode is continued.
By the steps, the system for automatically switching the remote controller mode and the mouse mode based on the scene switches the remote controller mode back to the remote controller mode from the mouse mode so as to realize automatic switching from the remote controller mode to the mouse mode and then from the mouse mode to the remote controller mode.
In the system and method for automatically switching the remote controller mode and the mouse mode based on the scene according to the embodiment, whether the remote controller mode and the mouse mode need to be switched can be judged according to the APP interface where the intelligent set top box of the IPTV is located currently, and the automatic switching between the remote controller mode and the mouse mode is realized according to the judgment result, so that an additional trigger mechanism is not required to be provided or an additional hardware module is not required to be added, the cost can be saved, and the user experience is improved.
Those of ordinary skill in the art will understand that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
