Abstract
The remote control comprises: a microprocessor including a CPU and a memory; a keyboard including a set of keys including one or more MACRO keys coupled to the microprocessor; lamp driver circuitry coupled to the microprocessor; circuitry for generating IR signals coupled to the IR lamp driver circuitry; code data for executing command functions which can be sent to a controlled device for causing the controlled device to perform specific functions stored in the memory; an entry/definition program in the memory for enabling a user of the remote control to define a macro for selecting at least one favorite channel by entry of series of keystroke commands on the keyboard; and a playback program in the memory for enabling an operator of the remote control to effect rapid selection of at least one favorite channel upon subsequent depression of the MACRO key.
