Abstract
The utility model relates to a digital television technology, in particular to a remote controller for a digital television set-top box. The utility model discloses a remote controller for a digital television set-top box. The technical proposal of the utility model is that: the remote controller for digital television set-top box comprises a microprocessor, a keyboard, an infrared transmitter unit, a touch screen unit and a gravity switch, the touch screen unit is connected with the microprocessor; the touch screen unit is supplied with electricity under of the control of output signals of the microprocessor; The output signals of the touch screen unit subject to the compression algorithm of the microprocessor are transmitted to the infrared transmitter to be sent. The utility mode has the advantages of combining the analog touch screen with the remote controller for the digital television set-top box to allow the remote controller to perform the basic remote control function for the digital television set-top box, and realizing character input when users are online.
Description
Technical field
The utility model relates to a kind of digital television techniques, particularly the digital TV set box remote control device.
Background technology
Country is carrying out Digital Television energetically at present, and developing rapidly as digital TV set-top box excessive between simulated television and the totally digitilized TV, simultaneously, its function is also from strength to strength, begin to realize and replace the function of some computers, as browse Internet, receiving and dispatching mail etc.But corresponding, the input equipment on the set-top box is also very original, can only import the cursor control of fixing several orders and limited service orientation key, can't adapt to existing requirement of using.
The utility model content
The purpose of this utility model is to overcome the shortcoming that above-mentioned existing remote controller exists, and a kind of digital TV set box remote control device that uses analog touch-screen to carry out cursor control is provided.
The utility model solves its technical problem, the technical scheme that adopts is, a kind of digital TV set box remote control device, comprise microprocessor, keyboard and infrared emission unit, it is characterized in that, also comprise touch screen unit, described touch screen unit comprises analog touch-screen, touch screen controller, two-way analog to digital converter; Described touch screen controller is connected with microprocessor; Described analog touch-screen is connected with touch screen controller; Described two-way analog to digital converter input is connected with analog touch-screen, and output is connected with microprocessor;
Further scheme is, also comprises gravity switch, and described gravity switch is connected with microprocessor.
The beneficial effects of the utility model are, analog touch-screen is combined with the digital TV set box remote control device, make its basic distant control function that both can finish digital TV set-top box, can also when the user surfs the Net, realize cursor control, and can realize the Chinese character input; And use analog touch-screen to carry out cursor control, have continuous steady when mobile, the resolution height, freedom of movement, advantage such as speed is fast, it realizes that effect can reach the level of computer mouse, and can realize mouse gestures; The input identification of touch-screen is finished by digital TV set-top box, has made full use of the disposal ability of existing set-top box CPU, and is less demanding to the disposal ability of remote controller end, reduced the cost of whole system.
Description of drawings
Fig. 1 is the structural representation of embodiment
Embodiment
Below in conjunction with drawings and Examples, describe the technical solution of the utility model in detail.
The utility model has increased touch screen unit and gravity switch on the digital TV set box remote control device, not only can finish the basic distant control function of digital TV set-top box, can also realize cursor control and Chinese character input when the user surfs the Net.
Embodiment
This example is to increase analog touch-screen at the back side of digital TV set box remote control device, increases by two buttons simultaneously or divide two buttons on touch-screen, is used for replacing the right and left key function of mouse.Concrete structure figure schematic diagram such as Fig. 1.
Send the signal controlling microprocessor whether to the touch screen unit power supply and scan analog touch-screen or keyboard by gravity switch.
When the remote control keys card made progress, gravity switch was in off-state, and microprocessor stops to power to touch screen unit, and while keyboard scan, obtain press key message sent by user, send to infrared emission unit in real time, this information is sent by infrared emission unit after deciphering;
When the remote control keys card downwards, analog touch-screen is installed simultaneously upwards the time, when gravity switch was in conducting state, microprocessor was powered to touch screen unit, stopped keyboard scan simultaneously; By scanning analog touch-screen, note all point coordinates information that touch-screen uses, through after the certain computing and packed data of microprocessor, do not do any pattern recognition, be sent to main frame by infrared emission unit in real time, by showing after the host process.
Because the touch screen unit circuit in the technical solutions of the utility model belongs to prior art, no longer describe in detail herein.Those of ordinary skill in the art according to foregoing description, can adopt various circuit to realize the technical solution of the utility model, and it all belongs to protection range of the present utility model.
