Claim Text:
1. A method comprising: directing a user to select a first indicator to radiate a first command signal of unknown modulation technique from a native remote control; interpreting, by a universal remote control programmer the first command signal to provide a first command code expressed in parameters of a pre-determined modulation technique, the parameters including a carrier frequency; determining, by the remote control programmer, based on correspondence between the first indicator and the first command code, if a command set of the native remote control can be uniquely identified; and in an event that the command set of the native remote control cannot be uniquely identified directing the user to select a second indicator to radiate a second command signal, wherein the first indicator and the second indicator are selected to minimize a number of indicators necessary to identify the command set of the native remote control; determining the shortest on period t(on) for which all other on intervals are integer multiples; inserting a zero length off period for each t(on) period; and determining the shortest off period t(off) for which all other off intervals are integer multiples; inserting a zero length on period for each t(off) period.
