1. A system for updating infrared control code information in a remote control device to be used to remotely control an electronic device, the system comprising:
- a data store storing particular infrared control code information for a particular electronic device, the particular infrared control code information for use by a remote control device to control the particular electronic device, the particular infrared control code information including a sequence of 1 and 0 bits;
at least one signal modulating device for obtaining the particular infrared control code information from the data store and for converting the particular infrared control code information to a sound wave signal, the at least one signal modulating device converting the particular infrared control code information by converting each 1 bit of the infrared control code information to a first sine wave pulse of a first frequency, and each 0 bit of the infrared control code information to a second sine wave pulse of a second frequency different than the first frequency, the at least one signal modulating device generating a pause pulse between each sine wave pulse representing each bit; and
a communication device for communicating the sound wave signal to the remote control device, which uses the sound wave signal to update the remote control device to control the particular electronic device.

12. A system for updating infrared control code information in a remote control device used to remotely control an electronic device, the system comprising:
-
a microphone for receiving a sound wave signal, the sound wave signal including first sine wave pulses of approximately a first frequency, second sine wave pulses of approximately a second frequency different than the first frequency, and pause pulses, each pair of sine wave pulses being separated by one of the pause pulses; and at least one signal demodulating device for demodulating the sound wave signal to generate the infrared control code information for use by a particular remote control device to remotely control a particular electronic device, the at least one signal demodulating device demodulating the sound wave signal by converting each first sine wave pulse following one of the pause pulses as a 1 bit and by converting each second sine wave pulse following one of the pause pulses as a 0 bit, the combination of the 0 bits and the 1 bits in the sound wave signal comprising the infrared control code information. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 23, 24)
