Description

A TV remote control device utilizing touchable buttons

technical field

The invention belongs to the technical field of digital home appliances, and in particular relates to a TV remote control device using touchable buttons.

Background technique

Application No. 200610036120.2 mentions a touch TV remote control capable of previewing programs. This technology enables the remote control to have a visual interface, preview programs on the remote control, and implement touch. However, the touch method used in this method is a touch screen, and it needs to be able to preview programs, so the touch screen is relatively large. For simple control, the use of a large-scale touch screen increases the cost, and affects the life and display effect of the touch screen. A remote control that can realize the program preview function needs 7 touchable buttons in total.

With the development of technology, the method of combining scroll bar and button function has become more and more common, and has the advantages of low cost, easy operation, long life and increased screen area. The cost of an ordinary screen is lower than that of a touch screen with the same area, which wastes a part of the area of the touch screen. On this basis, the screen area can be expanded without increasing the cost.

The disadvantage of the existing remote control is that there are too many buttons, which is very cumbersome for the user to use, requires a lot of memory, and is not easy to give feedback, and the user cannot intuitively know where he is and what he is doing.

As a kind of entertainment equipment, the TV set should also be able to better reflect the entertainment function with the matching remote control. But its cost is an important factor, which affects consumers' desire to buy. Therefore, the remote control should have the following characteristics: reasonable cost, visualization, a small number of buttons, and conform to the user's operating habits.

Contents of the invention

In order to overcome the deficiencies of the existing technology, the present invention provides a TV remote control device using touchable buttons, the user can use the least buttons to control the TV, and can use the remote control to preview or watch programs independently, which is ergonomic principle.

In order to realize the object of the invention, the technical scheme adopted in the present invention is as follows: the remote control device includes common buttons, touch buttons, LCD display screen, control signal sending module, remote controller central management module, program grouping and processing module, small screen display module , RF signal receiving module, key detection module.

There are 7 common buttons, which are responsible for handling shortcut key operations, confirming, canceling, and switching function menus.

The touchable button is composed of a vertical array of 4 touchable buttons and a horizontal array of 3 touchable buttons, responsible for selecting the LCD display area and realizing the scrolling function.

The control signal sending module is used for sending control information to the TV.

The central management module of the remote control converts user input into control commands and is responsible for processing and controlling video signals.

The program grouping and processing module is responsible for grouping the received video information and transferring it to the video buffer. It can also receive the control interface information from the central management module of the remote control and wait for the command of the central management module of the remote control to process the LCD output content. deal with.

The small screen display module is responsible for receiving instructions from the program grouping and processing modules, and fetching data from the video buffer for display.

The radio frequency signal receiving module is used for receiving TV signal input.

Button detection module for handling input.

The remote control device receives the TV signal input through the radio frequency signal receiving module, groups the TV signal according to the predetermined format through the program grouping and processing module, and sends a request to the remote control central management module and adjusts the output according to the module instruction, and then displays it on the small screen The module sends the output format and control signaling, and the small screen display module is triggered to output the content of the video buffer. The other process is used to listen to the user's operation. When the user performs a button operation, the button detection module triggers and makes a judgment, sends a request to the remote control central management module and transmits the button operation data, and the remote control central management module according to the machine The pre-stored information is used for matching judgment, and the control command is sent to the TV through the control signal sending module.

The connection between the radio frequency signal receiving module and the digital TV uses radio frequency signals.

The TV signal received by the radio frequency signal receiving module is obtained from the digital TV set-top box, which is divided into three ways, one way is to receive the channel program list, the other way is to intercept a certain frame of video for different channels according to the frequency, and the other way is to adjust the video frequency according to the frequency. Capture a frame from different channels and save it as a picture.

The program grouping and processing module will store channel number information and related display content for different channels when grouping. This module will buffer 3 pages of content after the current page being browsed. When the user switches pages, the remote controller sends an instruction to transmit the preview content of the new page to the TV through the control signal sending module.

The touch buttons are divided into two groups in layout, one is vertical, and the other is horizontal. The vertical corresponds to the vertical scroll bar, and the horizontal corresponds to the horizontal scroll bar. When the two groups of buttons are pressed, one program can be selected from 12 programs. The corresponding method is to mark the first column with the first button counted from the left horizontally, and then mark the first row with the first button counted vertically from top to bottom. This filters out the first button, and so on for other usages. In the process of browsing the program, the function of the vertical touch button is the same as that of the horizontal touch button. The vertical touch button is down or the horizontal touch button is to the right to turn the page backward, and the vertical touch button is up or the horizontal touch button is to the left to turn the page forward. When performing other operations on the remote control, the vertical touch button corresponds to the down button, the horizontal touch button to the right corresponds to the right button, the vertical touch button upward corresponds to the up button, and the horizontal touch button to the left corresponds to the left button.

The button detection module first detects the type of operation. For ordinary buttons, there are three different function buttons. If it is a shortcut key, it will find information from the shortcut key mapping table. The shortcut key mapping table can be changed by the user; if it is cancelled, return to the previous page . If it is confirmation, this key is used for confirmation on the page that requires the confirmation key. This key is multiplexed with the menu switching key. When the page does not need to use the confirmation key, this key will switch between different menus with the number of presses.

The remote control is set to sleep mode. When the user does not operate for a certain period of time, the remote control will automatically sleep. When the user inputs, the remote control wakes up and sends a wake-up signal to the set-top box. At this time, the remote control has the original video signal and displays , while updating the content. When the sleep time of the remote controller exceeds the shutdown time, the remote controller will be turned off. After that, the hold key becomes the switch key. When the hold key is on, all key requests are ignored.

The control signal sending module uses radio frequency signals to communicate with the digital TV set-top box. The conflict resolution method is: when the remote control is active, the remote control is the active party, and the TV sends a signal only after receiving the control signal from the remote control to avoid conflicts.

Effects brought by the present invention:

1. Use a graphical interface to replace traditional buttons, reduce user memory requirements, and the operation is simple and easy to understand. The operation options are not limited by buttons, which is convenient for combining with entertainment.

2. The remote control uses an LCD screen, which can reduce the burden on human eyes caused by digital TV switching, and is easy to locate, so that you can easily find the program that suits you.

3. The use of touch buttons can be combined with commonly used scroll bars, which is convenient and simple to use, reducing the gap between man and machine, and it has a matrix positioning function, which can reduce the cost of using the touch screen.

4. Due to the reduction of buttons, the size of the remote controller is reduced, and the use of a small number of compact button layout design can reduce the space required for the user's fingers to move and speed up the operation.

Detailed ways

The present invention will be further described below in conjunction with drawings and embodiments.

As shown in Fig. 1, the remote controller of the present invention only needs 12 buttons, which is half of the common remote controller, and the LCD is used, so that the control operation can be visualized.

As shown in Figure 2, the remote control device of the present invention is composed of common buttons, touchable buttons, LCD display screen, radio frequency signal receiving module 1, program grouping and processing module 2, small screen display module 3, remote controller central management module 4, control The signal sending module 5 and the key detection module 6 are composed. The radio frequency signal receiving module 1 is used for receiving TV signals. The program grouping and processing module 2 processes the received video information into groups and transfers them to the video buffer. It can also receive the control interface information from the central management module of the remote control and wait for the instructions from the central management module of the remote control to process the LCD output content. . The small screen display module 3 receives instructions from the program grouping and processing modules, and fetches data from the video buffer for display. The central management module 4 of the remote controller converts user input into control instructions, and is responsible for processing and controlling video signals. The control signal sending module 5 is used for sending control information to the TV. The button detection module 6 is used to process the input.

As shown in Figure 3, the remote controller receives the TV signal input through the radio frequency signal receiving module, groups the TV signal according to a predetermined format through the program grouping and processing module, and sends a request to the remote controller central management module and adjusts the output according to the module instruction, and then The output format and control signaling are sent to the small screen display module, and the small screen display module is triggered to output the content of the video buffer. The other process is used to listen to the user's operation. When the user performs a button operation, the button detection module triggers and makes a judgment, sends a request to the remote control central management module and transmits the button operation data, and the remote control central management module according to the pre-stored data in the machine The information is matched and judged, and the control command is sent to the TV through the control signal sending module.

The radio frequency signal receiving module 1 is connected by radio frequency technology, and the remote control does not need to be used for a long distance. The key is that the radio frequency module used by the digital TV set-top box and the remote control should be able to realize a fast and stable connection, so that the radio frequency signal receiving module 1 can receive TV signals normally. In addition to processing the program grouping and processing module 2 according to the received data, it also needs to process the control interface information, and the control interface information is provided by the remote control central management module 4. The key is that the image drawing of this module can simultaneously process video information and Interface information, when the control interface appears, the video playback is suspended. The control signal sending module 5 can use radio frequency or infrared. If radio frequency is used, the remote controller should be used as the active party.

In addition to realizing basic functions, energy consumption must be considered as a remote control, so the entire system must be able to perform self-maintenance, mainly energy-saving maintenance. The remote control central management module 4 will set a timer, and can adopt dormancy or even shutdown to save electric energy when the user does not operate. This embodiment adopts a three-layer energy-saving mode: brightness adjustment of the screen, dormancy, and shutdown.

The following describes each part separately:

1. Normal button

Such buttons include 4 shortcut buttons for quick input, confirmation/menu switching button, and cancel button. The function of the shortcut button can be customized, and the function information is saved in the remote control. The confirmation/menu switching button is multiplexed, and the specific function is determined by the usage scene displayed on the screen at that time. If the confirmation key is used, the confirmation key will be effective. When the key is pressed continuously, the menu switching function gets priority.

2. Tactile buttons

It consists of 7 buttons, which are divided into two parts: the first one is the selection button, the usage is shown in Figure 4, the screen is divided into a 4×3 matrix, and two buttons can determine a grid, which is mainly used for Program or block selection. The second function is the scroll bar. When the key is touched but not pressed, the counter starts and the key will be recorded. If the touch only stays on the key, it means that the user does not intend to operate. If the key is slid within 0.5 seconds to another block, the direction can be judged and sent to the central management module of the remote controller for processing. If it appears that the user starts to put their fingers on two buttons at the same time, judge the direction according to the finger that leaves. In other cases, it should be regarded as an illegal operation, and an error message should be displayed.

3.LCD display

Using a 3-inch LCD with a resolution of 320×240, each program occupies a space of 80×80, which can accommodate 4×3=12 channels in total. Interface control elements appear as menus from the bottom, overlaid on top of the video.

4. RF signal receiving module

The radio and television company provides signals to the digital TV, and the digital TV set-top box performs remote control playback service within a certain time range, and it scans different channels to obtain program previews. These signals will be sent to the remote controller through radio frequency signals. In order to avoid interference, the frequency of the radio frequency adopts a special frequency.

5. Program grouping and processing module

This module is the core processing module of the display. When grouping, channel number information and related display content will be stored for different channels. This module will buffer 3 pages of content after the current page being browsed. When the user switches the page, the button is triggered, and the remote controller sends an instruction to transmit the preview content of the new page to the TV through the control signal sending module. When the user presses a button, the central management module of the remote control issues a command to display the menu, and the program grouping and processing module responds to the command and draws a control interface.

6. Small screen display module

This module displays the content of the video buffer. This module is responsible for the first layer of energy-saving measures. When the user does not perform a page-turning operation within the first energy-saving effective time, the small screen display module will reduce the screen brightness; if the second energy-saving is effective If there is still no operation within the time, the small screen display module will turn off the screen.

7. Remote control central management module

This module is responsible for controlling signal input and key input, judging the key type and information, querying the user-defined library and converting it into corresponding commands, and outputting control interface information to provide the second and third layers of energy-saving measures. When the user still does not operate within the third energy-saving effective time, the central management module of the remote control will perform on-site protection, close most running processes, open the key response interrupt, and keep the timer. If the user still does not operate within the fourth energy-saving effective time, the central management module of the remote control shuts down the system until the user uses hold, touches reset, the system restarts, and reads the last saved scene content from the memory.

8. Control signal sending module

The control signal sending module uses radio frequency signals to communicate with the digital TV set-top box. The method of conflict resolution is: when the remote control is active, the remote control is the active party, and the TV sends a signal only after receiving the control signal from the remote control to avoid conflicts .

9. Button detection module

First, detect the operation type. For ordinary keys, there are three different function keys. If it is a shortcut key, look up the information from the shortcut key mapping table. The shortcut key mapping table can be changed by the user; if it is cancel, return to the previous page; if it is Confirmation, on the page that requires the confirmation key, this key is used for confirmation, when the page does not need to use the confirmation key, this key will switch different menus with the number of presses.
