Abstract
The present invention relates to field of set-top, disclose a kind of set top box with laser-projection keyboard function, including set top box system of subject, keyboard image projection module, infrared image acquisition and processing module and infrared laser alignment system, the keyboard image projection module, infrared image acquisition are connected with processing module and infrared laser alignment system with set top box system of subject, and input data realizes laser-projection keyboard function.Consumer's Experience and online convenience are improved using the technical scheme.
Description
Technical field
The present invention relates to field of set-top, more particularly to a kind of set top box with laser-projection keyboard function.
Background technology
Present Intelligent set top box has increasing function of surfing the Net requirement, and user inputs typically by remote control, but
When carrying out the input of the words such as network address letter, character with remote control, to be switched by multiple remote keying to realize, Er Qiejing
Often there is the problems such as keys deactivation, not enough power supply loose contact, bring input efficiency low to user, error rate is high, and use is not square
Just experience is waited.
The content of the invention
The purpose of the embodiment of the present invention is to provide a kind of set top box with laser-projection keyboard function, effectively increases use
Family online experience.
A kind of set top box with laser-projection keyboard function provided in an embodiment of the present invention, including set top box system of subject,
Keyboard image projection module, infrared image acquisition and processing module and infrared laser alignment system, the keyboard image projective module
Block, infrared image acquisition are connected with processing module and infrared laser alignment system with set top box system of subject, and input data is realized
Laser-projection keyboard function.
Alternatively, the set top box system of subject is by master chip, internal memory, modulator, audio frequency and video output, CA interfaces, network
Interface, external storage controller composition
Therefore using the present embodiment technical scheme, due to using dummy keyboard projection input, improving input efficiency
With user's online experience, there is excellent operability, the benign development for promoting whole set top box industry to be interacted with internet.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
There is the required accompanying drawing used in technology description to be briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments of invention, for those of ordinary skill in the art, without having to pay creative labor, may be used also
To obtain other accompanying drawings according to these accompanying drawings.
Fig. 1 is a kind of set up box structure figure with laser-projection keyboard function provided by the invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Embodiment：
There is increasing function of surfing the Net requirement to solve Intelligent set top box, and traditional remote controller input efficiency is low, goes out
Error rate is high, inconvenient problem with use, and the present embodiment provides a kind of set top box with laser-projection keyboard function, realizes virtual key
Disk projection input, as shown in figure 1, including the set top box system of subject 10, keyboard image projection module 20, infrared image acquisition
With processing module 30 and infrared laser alignment system 40, it can be, but not limited to, the set top box system of subject 10 is by master chip, interior
Deposit, modulator, audio frequency and video export, CA interfaces, network interface, external storage controller composition.The keyboard image projection module
20th, infrared image acquisition is connected with processing module 30 and infrared laser alignment system 40 with set top box system of subject 10, inputs number
Factually show laser-projection keyboard function.When using laser-projection keyboard, it is projected out using the keyboard image projection module 20
The virtual graph of keyboard, when finger touches the virtual graph of keyboard, the infrared laser alignment system 40 senses the resistance of signal
It is disconnected, and the infrared image acquisition and processing module 30 are sent a signal to, by the infrared image acquisition and processing module 30
Process signal data, so as to extrapolate user's button to be inputted.
Inputted it can be seen that the input of this programme dummy keyboard can be laid out with analog mechanical key board, input efficiency is high, accuracy
It is good, space is saved, it is convenient to use and surf the Net.
Embodiments described above, the restriction to the technical scheme protection domain is not formed.It is any in above-mentioned implementation
Modifications, equivalent substitutions and improvements made within the spirit and principle of mode etc., should be included in the protection model of the technical scheme
Within enclosing.
