Problems solved by technology

[0005] However, existing systems are not well equipped to use a wide range of infrared subcarrier frequencies, and because infrared signals can have many coding schemes, it is not always easy to recover an infrared signal from a transmitted radio frequency (radio frequency) signal easy
Simultaneously high frequency and low cost RF transmission is not possible or at least very difficult to obtain

Embodiment Construction

[0032] figure 1 An embodiment of the method and system of the present invention is schematically illustrated in which the range of an infrared remote control system is extended. The following components are present in room 1 and a separate room 2. An infrared remote control unit 3 comprising an infrared transmitter 4 for transmitting an infrared signal 5 on an infrared subcarrier, a radio frequency transmission system 6 comprising a radio transmitter 8 coupled to a radio transmitter 8 for responding to the infrared signal 5 Infrared receiver 7 which transmits radio signal 10 (in this case via antenna 9).

[0033] The radio receiver 13 receives the radio signal 10 via the antenna 11 which is coupled to the infrared transmitter 14 for generating the infrared signal 15 . The infrared signal 15 is received by an infrared receiver 16 connected to a controlled device such as a VCR.

[0034] figure 2 Features of heretofore known methods and systems are schematically illustrated....

Abstract

In a method of operating a remote control system and in such a system comprising an RF transmission and receiving system and an IR transmission device the sub-carrier information of the IR signal is transmitted in the RF signal in a signal separate from the envelope information of the IR signal which is contained in a envelope signal.

Description

technical field [0001] The present invention relates to a control method of a remote control system including a radio frequency transceiver system, wherein the radio frequency transceiver system includes a radio transmitter for transmitting a radio frequency signal and a radio receiver for receiving the radio frequency signal sent by the radio transmitter, so The receiver is coupled to an infrared transmitter for transmitting an infrared signal on the infrared subcarrier in response to receipt of the radio frequency signal. [0002] The invention also relates to a remote control system comprising a radio frequency transceiver system, wherein the radio frequency transceiver system comprises a radio transmitter for transmitting a radio frequency signal and a radio receiver for receiving the radio frequency signal transmitted by a radio receiver, the receiver is coupled to an infrared transmitter for transmitting an infrared signal on the infrared subcarrier in response to receip...
