摘要

The receiver has a demodulation and decoding module (10) to demodulate and decode digital TV signals according to user commands, and a user interface to receive and transmit the user commands to the module. The user interface includes a power supply circuit (12) to supply voltage to the module in response to a power supply command, and to supply power to the user interface. The user interface includes a user command processing circuit (14) to partially filter the user commands from a remote control (11) and to generate power supply commands based on the user commands.
