Abstract

A system and a method of controlling an RF transceiver are provided. The system includes a key input unit for detecting a key selection, a memory unit storing control data required for operating the RF transceiver and a code table matching with a key value, a liquid crystal display (LCD) for displaying operational information of the RF transceiver, a controller for turning off the LCD that is in an on-state when a data transmitting/receiving request is detected from the key input unit and turning on the LCD when the data transmitting/receiving is completed, and an RF transmitting/receiving unit for modulating a transmitting signal, power-amplifying the transmitting signal, transmitting the amplified signal as an RF signal to an object device through an antenna, and receiving a response signal as an RF signal from the object device.

Claims

1. A system for controlling a radio frequency (RF) transceiver, comprising:

a key input unit for detecting a key selection;

a memory unit storing control data required for operating the RF transceiver and a code table matching with a key value;

a liquid crystal display (LCD) for displaying operational information of the RF transceiver;

a controller for turning off the LCD that is in an on-state when a data transmitting/receiving request is detected from the key input unit and turning on the LCD when the data transmitting/receiving is completed; and

an RF transmitting/receiving unit for modulating a transmitting signal, power-amplifying the transmitting signal, transmitting the amplified signal as an RF signal to an object device through an antenna, and receiving a response signal as an RF signal from the object device.

2. The system of claim 1, further comprising a light emitting diode (LED) for displaying an operation state of the RF transceiver in accordance with a control of the controller in a state where the LCD is turned off.

3. The system of claim 1, wherein, when the RF transceiver is a multipurpose remote controller, the memory unit stores a lessened control code table for the object device.

4. The system of claim 1, wherein, when the RF transceiver is a one-way communication type that is designed to only transmit the RF signal, the controller transmits the RF signal in response to a data transmission request in a state where the LCD is turned off, and when there is no transmission request for a predetermined time after the RF signal is transmitted, the controller determines that the RF signal transmission is completed and thus turns on the LCD.

5. The system of claim 1, wherein, when a device ID contained in a response signal from the object device is analyzed and it is determined that the analyzed device ID corresponds to an ID of the transceiver, the controller determines that the RF signal transmitting/receiving is completed and subsequently turns on the LCD.

6. A method of controlling a radio frequency (RF) transceiver, comprising:

determining if a data transmitting/receiving request from a key input unit is detected in a standby mode where a liquid crystal display (LCD) maintains an on-state;

converting, when the data transmitting/receiving request is detected, data into a code value and turning off the LCD;

modulating the converted code value, power-amplifying the modulated code value, and transmitting the amplified code value as an RF signal;

determining if the data transmitting/receiving is completed by analyzing a response signal that is transmitted as an RF signal from an object device; and

turning on the LCD when it is determined that the data transmitting/receiving is completed.

7. The method of claim 6, further comprising, when one or more RF transceivers transmit and receive the RF signal to and from one host, transmitting data containing a device ID of a current transceiver as the RF signal to the host in a state where the LCD is turned off, and turning on the LCD by determining that the data transmitting/receiving is completed when the device ID of the current transceiver is detected by analyzing the device ID contained in a response signal transmitted from the host.

8. The method of claim 6, further comprising, when the RF transceiver is a one-way communication type that only transmits the RF signal, transmitting the RF signal in response to a data transmission request in a state where the LCD is turned off, and turning on the LCD by determining that the RF signal transmission is completed when there is no transmission request for a predetermined time after the RF signal is transmitted.
