Abstract

A remote control system includes a remote control receiver storing an operation code controlling an electronic device, and a remote control transmitter operable to store a received operation code. The remote control receiver is operable to read the stored operation and to transmit the read operation code to the remote control transmitter. The remote control transmitter is operable to store the transmitted operation code, and to transmit the stored operation code to the remote control receiver according to operation on the operation unit. The remote control receiver is operable to control the electronic device according to the operation code transmitted from the remote control transmitter. The remote control system remotely controls the electronic device reliably with simple operation.

Claims

1. A remote control system comprising:

a remote control receiver storing a first operation code controlling a first electronic device; and

a first remote control transmitter including an operation unit, wherein

the remote control receiver is operable to;

read the stored first operation code; and

transmit the read first operation code to the first remote control transmitter,

the first remote control transmitter is operable to;

store the transmitted first operation code; and

transmit the first operation code stored in the first remote control transmitter to the remote control receiver according to operation on the operation unit, and

the remote control receiver is operable to control the first electronic device according to the first operation code transmitted from the remote control transmitter.

2. The remote control system of claim 1, wherein

the operation unit of the first remote control transmitter includes a first operation key and a second operation key,

the remote control receiver is operable to:

store a second operation code controlling the first electronic device;

transmit a key address map to the first remote control transmitter, the key address map showing an allocation for allocating the stored first operation code and the stored second operation code stored to the first operation key and the second operation key of the first remote control transmitter, to the first remote control transmitter;

read the stored first operation code and the stored second operation code,

transmit the read first operation code and the read second operation code to the remote control transmitter,

the first remote control transmitter is operable to;

allocate the transmitted first operation code and the transmitted second operation code to the first operation key and the second operation key according to the key address map; and

transmit the first operation code and the second operation code allocated, to the remote control receiver according to operation on the first operation key and the second operation key, and

the remote control receiver is operable to control the first electronic device according to the first operation code and the second operation code transmitted from the remote control transmitter.

3. The remote control system of claim 1, further comprising a second remote control transmitter storing a second operation code controlling the second electronic device, wherein

the second remote control transmitter is operable to transmit the stored second operation code to the remote control receiver,

the remote control receiver is operable to transmit the transmitted second operation code to the first remote control transmitter, and

the first remote control transmitter is operable to:

allocate, to the operation unit, the second operation code transmitted from the remote control receiver; and

transmit the allocated second operation code to the second electronic device according to operation on the operation unit as to control the second electronic device.

4. A remote control transmitter for a remote control system including the remote control transmitter and a remote control receiver controlling an electronic device, the remote control transmitter comprising:

a transmitting unit;

a receiving unit; and

a controller, wherein

the controller is configured to generate a first message including a pairing code to be sent to the remote control receiver by the transmitting unit,

the receiving unit receives a reply message including an authentication code and a key address map from the remote control receiver, the key address map including plural operation codes corresponding to operation commands of the electronic device, and

the controller is configured to generate a command message to be sent to the remote control receiver including one of the plural operation codes and the authentication code by the transmitting unit.
