A conventional FVAL system will be described.

1 is a connection diagram showing a connection of a conventional TV system and a TV.

Referring to FIG. 1, the conventional TV system is provided with input means for receiving digital TV broadcasting, digital satellite broadcasting, and digital cable broadcasting, and signals high quality video / audio digital data input through the input means. It processes and records on the large capacity storage media built in itself.

A configuration for performing the recording function is shown in FIG.

FIG. 2 is a block diagram of a circuit of a conventional FV system.

Referring to Figure 2 will be described the configuration of a conventional FB system.

FVAL central processing unit 210 controls the FVAL system as a whole.

The MPEG (Moving Picture Expert Group) decoder 260 receives a broadcast signal output from the tuner 201 and MPEG-decodes the broadcast signal.

The video digital to analog converter (DAC) / NTSC decoder 240 converts digital video data among the signals output from the MPEG decoder 260 into analog video data and outputs the analog video data.

A north bridge 220 controls the data flow between the CPU 210, the video DAC / NTSC decoder 240, and the memory 221.

The video port 241 outputs an analog video signal output from the video DAC / NTSC decoder 240 to an image display device (not shown).

The audio DAC 250 converts digital audio data among analog signals output from the MPEG decoder 260 into analog audio data and outputs the analog audio data.

South Bridge 230 is responsible for interfacing with the audio DAC 250 and controls the flow of data through other PCI or IDE buses.

The audio port 251 outputs an analog audio signal output from the audio DAC 250 to a speaker (not shown).

The mass storage means HDD 270 and the DVD 480 store high quality high quality video / audio data.

The third memory 221 and the fourth memory 261 temporarily store data necessary for signal processing.

It describes the operation of the conventional FB system configured as described above.

The MPEG decoder 260 decodes the digital broadcast stream input from the tuner and outputs the decoded digital broadcast stream to the north bridge 220 and the south bridge 230.

The north bridge 220 outputs video data from the input signal to the video DAC / NTSC decoder 240, and the signal converted into an analog video signal by the video DAC / NTSC decoder 240 is a video port 241. It is supplied to the image display unit through.

The south bridge 230 outputs audio data from the input signal to the audio DAC 270, and the signal converted into an analog signal by the audio DAC 270 is supplied to the speaker through the audio port 251. .

At this time, the user inputs a recording command to the FV system in order to record the digital broadcasting contents currently being serviced.
