  • Patent number: 6195033
    Abstract: The invention teaches remote control device for reassigning functions associated with one key to another key, wherein the functions are stored in memory. In one embodiment the remote control comprises a memory and a plurality of function instructions stored in the memory, including a first function instruction and a second function instruction. A plurality of keys, including a first key, is operably connected to execute the first function instruction. Reassignment programming is stored in memory and provides for connecting the first key such that it will execute the second function instruction instead of the first function.

  • Patent number: 5414426
    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.
