Please refer to Fig. 1, it illustrates the structure chart of ratio frequency remote control receiving device according to an embodiment of the invention.The ratio frequency remote control receiving device 100 of the embodiment of the invention is installed on TV card/box (TV card 430 shown in Fig. 4 A or the TV box 440 shown in Fig. 4 B), and it includes reception antenna 130, radio frequency chip 110 and connector 120.Radio frequency chip 110 then includes reception transmitter module 114 and processing module 112.
Reception antenna 130 is used for receiving the radiofrequency signal that wireless radio frequency remote control device (the wireless radio frequency remote control device 410 shown in Fig. 4 A) is sent.Receive transmitter module 114 and be coupled to reception antenna 130, the radiofrequency signal that is used for receiving is converted to received signal.112 of processing modules are coupled to and receive transmitter module 114, are used for converting received signal to control signal 144, so as to control TV card/box.Connector 120 is electrically connected at processing module 112, is used for control signal 144 is sent to TV card/box.
In the present embodiment, receive transmitter module 114 radiofrequency signal is zoomed into received signal, and received signal is delivered to processing module 112 handle.
In some cases, processing module 112 also can be encoded before sending control signal 144, is sent to decoding module (decoding module 434,444 shown in Fig. 4 A and Fig. 4 B) in TV card/box by connector 120 again.Wherein the coding of processing module 112 allows the control signal 144 that is encoded decipher through the decoding module in TV card/box corresponding to the decoding module in TV card/box, and then control TV card/box.Whereby, ratio frequency remote control receiving device 100 can limit and be used in specific TV card/box, avoid problem compatible between ratio frequency remote control receiving device 100 and TV card/box (the control signal definition is different between for example different label TV card/boxes), and TV card/box manufacturer also can carry out design optimization at ratio frequency remote control receiving device 100, improves the efficient of ratio frequency remote control receiving device 100 control TV card/boxes.
In addition, the radio frequency chip 100 of present embodiment also comprises power module 116, is used for the power supply signal 142 of TV card/box is converted to the running power supply of ratio frequency remote control receiving device 100.Therefore, connector 120 is except that transmitting control signal 144, also in order to transmit power supply signal 142 and earth signal 146.
Then please refer to Fig. 2, this is the structure chart of the ratio frequency remote control receiving device of another embodiment of the present invention.Ratio frequency remote control receiving device 200 is roughly the same with previous embodiment, has radio frequency chip 210, reception antenna 230 and connector 220.210 of radio frequency chips include reception transmitter module 214, processing module 212 and power module 216.Because the main mode of connection of present embodiment said elements is most of identical with previous embodiment with function, therefore identical part is not just given unnecessary details at this.
Ratio frequency remote control receiving device 200 that it should be noted that present embodiment also includes battery 250, and the running power supply of ratio frequency remote control receiving device 200 is provided.Therefore, power module 216 is converted to the required running power supply of this ratio frequency remote control receiving device with the power supply signal 242 of battery 250 in the present embodiment.220 of connectors have control signal 244 and earth signal 246 circulations.
For the mechanism of the ratio frequency remote control receiving device of the detailed ground explain embodiment of the invention more, please refer to Fig. 3, this is the operational flowchart of a kind of system of embodiments of the present invention.At first step 300 is launched control signal by the wireless radio frequency remote control device.Follow step 310, ratio frequency remote control receiving device receives control signal.Then step 320 is carried out conversion of signals by ratio frequency remote control receiving device again, perhaps further encodes.Final step 330 is sent to TV card/box to control with the control signal of changing, encoding out.
And in order to understand the range of application of the embodiment of the invention more, please be simultaneously with reference to Fig. 4 A and Fig. 4 B.This is the application schematic diagram of the embodiment of the invention.Wireless radio frequency remote control device 410 has telecontrol antenna 412, radio frequency chip 414 and battery 416.TV card/box 430,440 has control connection interface 432,442.420 of ratio frequency remote control receiving devices have reception antenna 424 and radio frequency chip 426 and connector 422.
Ratio frequency remote control receiving device 420 then receives the radiofrequency signal that wireless radio frequency remote control device 410 is sent, and converts the control signal of TV card/box 430,440 to by radio frequency chip 426.422 of connectors make ratio frequency remote control receiving device 420 electrically connect by connector 422 and this TV card/box 430,440 corresponding to 432,442 designs of control connection interface.
When TV card/box 430,440 has the control connection interface 432,442 that design can be installed infrared inductor, to utilize infrared remote controller to send infrared signal, and when using infrared inductor that the infrared signal that receives is converted to control signal, control connection interface 432,442 is the infrared inductor connector.At this moment, the connector 422 of ratio frequency remote control receiving device 420 can be designed to identical with infrared inductor, make ratio frequency remote control receiving device 420 can be inserted in control connection interface 432,442, just can utilize wireless radio frequency remote control device 410 to control TV card/box 430,440.
And when the infrared inductor connector is designed to audio connector (TRS connector) specification, the specification that connector 422 also meets, and because the infrared inductor connector is female joint, so connector 422 is male joint.
Certainly, the specification of control connection interface 432,442 and connector 422 is not only as described in the embodiment, also required frequency range of viewable design person and cost take into account line translation, only need make connector 422 can be electrically connected at control connection interface 432,442 and transmit control signal and get final product.
And reception antenna 424 and telecontrol antenna 412 are in the present embodiment, realize with circuit board antenna, having lower cost, and reach the purpose of dwindling ratio frequency remote control receiving device 420 and the volume of wireless radio frequency remote control device 410.Actual application also can otherwise realize according to designer's consideration.
Therefore the ratio frequency remote control receiving device of the embodiment of the invention receives radio frequency signal and is converted to control signal and controls TV card/box.The user need not remote controller is aimed at receiving device whereby, i.e. may command TV card/box.If TV card/box is provided with control connection interface (for example infrared inductor connector), and the connector of ratio frequency remote control receiving device also is designed to corresponding specification, can replace the infra-red remote control inductor, be installed on the control connection interface, allow the user can obtain the benefit of omni-directional remote control with minimum cost.
And if having a decoder in TV card/box, then ratio frequency remote control receiving device one can be encoded corresponding to encoder, can limit whereby and be used in specific TV card/box, avoid problem compatible between ratio frequency remote control receiving device and TV card/box (the control signal definition is different between for example different label TV card/boxes), and TV card/box manufacturer also can carry out design optimization at ratio frequency remote control receiving device, improves the efficient of ratio frequency remote control receiving device control TV card/box.
Though the present invention discloses as above with execution mode; right its is not in order to limit the present invention; any those of ordinary skills; without departing from the spirit and scope of the present invention; when can being used for a variety of modifications and variations, so protection scope of the present invention is as the criterion when looking the scope that the accompanying Claim book defined.
