Embodiment Construction

[0039] Embodiments of the present invention will be described with reference to the drawings.

[0040] The present invention relates to a remote control system for remotely operating a television receiver, a DVD player, another type of AV equipment, another type of CE equipment, information equipment, etc., using a remote controller.

[0041] Although a communication system based on infrared radiation, that is, an infrared remote control, is generally used for remote control operations of equipment, such an infrared communication system has a problem of directionality. Communication can only be established if the light-receiving part of the receiver is placed within the field of view of the transmitter. This is a significant constraint in use. In addition, since such infrared communication systems are basically based on one-way communication, the transmitter cannot receive a response from the receiver. Therefore, transmission confirmation cannot be performed.
