US 6,211,797 B1 · Infrared communication control apparatus and method

Abstract

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 are related to a plurality of infrared communication schemes, respectively. When the communication port is opened, a communication port controller refers to a relating information table of a memory to send relating information to an infrared protocol selector and an infrared modulation/demodulation scheme selector. An IrDA infrared protocol generator, an ASK infrared protocol generator or a consumer IR infrared protocol generator is selected, and then an IrDA modem, an ASK modem or a consumer IR modem is selected. Data communication of infrared signals is conducted through an infrared unit in accordance with the protocol and the modulation/demodulation scheme thus selected.

Dependent claims

An infrared communication control apparatus comprising:

a plurality of communications ports, each said communication port having an open configuration and a closed configuration, and being respectively related to a plurality of infrared communications schemes;
selecting means for selecting, prior to the operation of said apparatus to receive and/or transmit data when at least one of the plurality of communications ports is in its open configuration, a protocol and modulation/demodulation scheme of a selected one of the infrared communication schemes related to the at least one communication port to be opened;
protocol generating means for generating data conforming to the protocol selected by the selecting means;
and
infrared modulation/demodulation means for modulating the data generated by the protocol generating means in accordance with the modulation/demodulation scheme selected by the selecting means to generate and transmit infrared signals, and for demodulating received infrared signals into data.
