Abstract

Disclosed is an IR data transmitting device having an ID that converts a RF signal received from a remote controller into an IR signal and transmits it to a device to be controlled. The IR data transmitting device having an ID includes a remote controller provided with an IR transmitter for transmitting an IR signal and a RF transmitter for adding a distinguishment ID allocated to the remote controller to a RF signal and transmitting the RF signal added with the ID; and a relay for receiving the RF signal added with the distinguishment ID from the RF transmitter of the remote controller to check the distinguishment ID, removing the distinguishment ID from the RF signal added with the distinguishment ID according to whether the distinguishment ID is identical to a previously stored set ID or not, and then converting the RF signal from which the distinguishment ID is removed into an IR signal to output the IR signal to a device.

Description

technical field [0001] The present invention relates to an infrared (IR, Infrared Ray) data transmitting device, in particular to a device with identification (ID, Identification), which converts a radio frequency (RF, Radio Frequency) signal received from a remote controller into an IR signal, and Send it to the IR data transmitter of the controlled device. Background technique [0002] Generally, IR data transmission technology is used for data transmission between different devices, such as: data transmission between personal computers and mobile devices. However, the characteristics of data transmission using IR are: due to its basic characteristics in the application field, as well as being limited by the field of view and distance between the IR sending unit of the signal output device and the IR receiving unit of the controlled device, The transmission distance is limited within 5 meters. [0003] Therefore, it is required to solve the problem of limited transmissio...
