Abstract

An analog/digital set-top box is used with a digital TV signal source, an analog TV signal source and a display. The analog/digital set-top box includes a housing; a digital demodulating unit disposed in the housing for receiving and demodulating a digital TV signal outputted by the digital TV signal source into a digital data flow; a decoder disposed in the housing and electrically connected to the digital demodulating unit for receiving and decoding the digital data flow into a first image signal; an analog demodulating unit disposed in the housing for receiving and demodulating an analog TV signal outputted by the analog TV signal source into a second image signal; an image signal processor disposed in the housing and electrically connected to the decoder, the analog demodulating unit and the display for receiving and processing the first and second image signals into a display signal for the display; and a micro-controller disposed in the housing and electrically connected to the digital demodulating unit, the decoder, the analog demodulating unit and the image signal processor for controlling the image signal processor to select and process one of the first and second image signals in response to a change of a using status, thereby outputting the display signal corresponding to the first or second image signals.
