Infrared communication control apparatus and method

摘要

An object of the invention is to make it possible to switch a plurality of infrared communication schemes without depending on an automatic detection of infrared signals. A plurality of communication ports (11A, 11B, ..., 11n) are related to a plurality of infrared communication schemes, respectively. When the communication port (11) is opened, a communication port controller (12) refers to a relating information table (24) of a memory (26) to send relating information to an infrared protocol selector (13) and an infrared modulation/demodulation scheme selector (18). An IrDA infrared protocol generator (14), an ASK infrared protocol generator (15) or a consumer IR infrared protocol generator (16) is selected, and then an IrDA modem (19), an ASK modem (20) or a consumer IR modem (21) is selected. Data communication of infrared signals (27) is conducted through an infrared unit (23) in accordance with the protocol and the modulation/demodulation scheme thus selected.
