Minimal function remote control without digit keys and with a power toggle program and with a channel rotation program

摘要

The remote control comprises: a microprocessor including a CPU and memory; a keypad including several keys coupled to the microprocessor for operating the remote control, some of the keys being a "POWER" key, a "Channel Up" key and a "Channel Down" key; lamp driver circuitry coupled to the microprocessor; structure and program instructions, including said microprocessor, for generating infrared (IR) signals coupled to the IR lamp driver circuitry; and code data for executing command functions for operating a home entertainment device stored in the memory. A power toggle program is stored in the memory for effecting the sending of the IR code for "STANDBY" or the IR code for the number digit "1" each time the power key is pressed. Also a channel rotation program is stored in the memory for effecting the sending of digit number signals in an ascending or descending order number digit each time the "Channel Up" key is pressed or the "Channel Down" key is pressed.
