主权项

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.
