DIRECT ENTRY REMOTE CONTROL WITH CHANNEL SCAN

摘要

The remote control (10) comprises a microprocessor including a CPU and memory, a keypad (20) including keys (25) for operating the remote control coupled (10) to the microprocessor (38) IR, lamp driver circuitry (62) coupled to the microprocessor (38), hardware and software, including the microprocessor (38), for generating infrared (IR) signals coupled to the IR lamp driver circuitry (62), code data for executing command functions for operating a home entertainment device stored in the memory. The keys (25) include a SCAN key (28), circuitry for coupling the SCAN key (28) to the microprocessor and a channel scan program stored in the memory for effecting a channel scan of channels when the SCAN key (28) is depressed.
