Receiving infrared communications on a mobile device

摘要

A system and a method are disclosed for receiving an infrared signal on a mobile device. The mobile device receives an infrared signal by creating an intermediate bitstream based on the received infrared signal. The intermediate bitstream is trimmed, downsampled, and demodulated in the time domain. The intermediate bitstream is then converted into a raw infrared code. The received bitstream is processed in a software layer, enabling the mobile device to process infrared signals without the use of additional hardware configured on the mobile device.

1. A method of receiving an infrared signal to generate an infrared code on a computing device, comprising:
generating a clock signal on a data bus from a processor, the data bus connecting an infrared system to the processor configured on the computing device, the clock signal disconnected from the infrared system; receiving, at the infrared system, an infrared signal that is transmitted on data bus; generating, through the data bus, an intermediate signal on the processor by sampling the infrared signal at an operating frequency determined by the clock signal, the intermediate signal comprising a plurality of bits; receiving a waveform of the infrared signal; determining a carrier frequency of the infrared signal based on an analysis of the waveform; and generating the infrared code based on the intermediate signal and the carrier frequency.
