Patent ID: 8139942

Claim:
A remote controlling system, comprising: an infrared remote controller which generates a first serial signal containing a command corresponding to a user's operation and outputs the first serial signal by infrared communication; a radio remote controller which generates a code signal containing a key number corresponding to a user's operation and outputs the code signal by radio communication; and an electronic device having: a light receiving section which receives the first serial signal and outputs the first serial signal, a radio receiving section which receives the code signal, converts the code signal into a second serial signal containing a command corresponding to the key number, and generates a control signal which denotes that the code information has been received, and outputs the second serial signal and the control signal, a selecting section which receives the first serial signal, the second serial signal and the control signal and which selects one of the first serial signal and the second serial signal based on the control signal and outputs the selected serial signal such that while the control signal is being supplied, the selecting section selects the second serial signal, and a controlling section which controls the electronic device based on the first serial signal or the second serial signal selected by the selecting section, wherein the radio receiving section starts converting the code signal into the second serial signal after the radio receiving section has started generating the control signal and a predetermined time has elapsed, and the radio receiving section completes generating the control signal after the radio receiving section has completed outputting the second serial signal to the selecting section and a predetermined time has elapsed.
