The tuner 11 tunes a broadcast signal input through an antenna and tunes to a specific frequency to output a video / audio signal of a broadcast program to the encoder / decoder unit 12, and the encoder / decoder unit 12 is input. The video / audio signal is compressed or decompressed and output to the north bridge 22 and the south bridge 24 through the PCI bus.

The north bridge 22 and the south bridge 24 are connected through a PCI bus, which is a type of system bus, to collectively manage the DV set-top box system, and the north bridge includes a control unit 20 and a memory 21 such as RAM. ), While the south bridge 24 is connected to the storage unit 18 or the disk loader 19, etc., while controlling data exchange between devices having a relatively high data transfer rate such as a video processor 14 for processing an image signal. It is connected to Integrated Drive Electronics (IDE), Peripheral Component Interconnect (PCI), and Universal Serial Bus (USB) to control data exchange.

Accordingly, the broadcast program output from the tuner is compressed by the encoder / decoder unit 12 and stored in the storage unit 18 or recorded on an optical disc (eg, DVD or CD) through the disk loader 19. The video / audio signal of the broadcast program is output to the video processor 14 and the audio processor 16, respectively, and converts the digitized video / audio signal into analog and connects the video port 15 and the audio port 17 to each other. By outputting to a video display device such as a TV through the user can watch or record a broadcast program.

In addition, the storage unit 18 stores the video / audio data output from the encoder / decoder unit 12, that is, a broadcast program that is stored in a broadcast program or a scheduled recording set through an electronic program guide (EPG). Can be.
