INFRARED COMMUNICATION APPARATUS AND INFRARED COMMUNICATION METHOD

摘要

An infrared communication apparatus and infrared communication method are provided as those enabling data communication with a receiving device, regardless of a protocol with which the receiving device is compatible. An apparatus is provided with a transmitting unit 100 for performing transmission of a first packet to inquire whether a receiving device 2 is compatible with a first protocol and transmission of a second packet to inquire whether the receiving device 2 is compatible with a second protocol, to the receiving device 2 at least once, and thereafter transmitting a plurality of third packets to inquire whether the receiving device is compatible with a third protocol, to the receiving device 2; a receiving unit 104 for receiving a response packet to indicate a protocol with which the receiving device 2 is compatible, from the receiving device 2 having received the first packet, the second packet, and the plurality of third packets; and a data transmitting unit 106 for transmitting data to the receiving device 2, based on the protocol indicated by the response packet received by the receiving unit 104.
