<p>The remote control (10) comprises: a microprocessor (38) including a CPU (44) and a memory (40, 42); a keyboard (20) coupled to the microprocessor (38) and including a set of keys (25) including at least one MACRO key; IR lamp driver circuitry (62) coupled to the microprocessor (38); light emitting circuitry for generating and emitting IR signals coupled to the IR lamp driver circuitry (62); code data for creating the IR signals, which are sent by the light emitting circuitry to a controlled device to cause the controlled device to perform specific command functions stored in the memory (40, 42); a macro entry/definition program in the memory (40, 42) for enabling a user of the remote control (10) to define a macro for selecting at least one favorite channel by entry of a series of keystoke commands on the keyboard (20); and a macro playback program in the memory (40, 42) for enabling an operator of the remote control (10) to effect rapid selection of at least one favorite channel upon subsequent depression of the at least one MACRO key.</p> |
