Abstract

A remote control for consolidating several native remote controls of consumer electronic devices identifies, stores and re-transmits signals of the other remote controls for operating several of the electronic devices with one remote control unit. The remote control includes a receiver, a microprocessor, memory, and a transmitter. The remote control identifies a Protocol or transmission technique of each native remote control by comparing a transmitted signal from the native remote control to a preprogrammed data base of Protocols of the universal remote control. During the identification process, frequency and cycle count are detected to determine a Protocol carrier family. Pause and bit modulation information of the transmitted signal are detected for further refining the selection of the Protocol from the preprogrammed data base of Protocols. Finally, a second signal is examined to make the final selection of the correct Protocol. By knowing the bit modulation technique or how the bit is being sent, the universal remote control detects the code pattern of the transmitted signal and stores the code pattern and identified Protocol for later re-transmission to remotely control the electronic device.
