Signal flow Record Mode
All video and audio record signals from tuner assembly, composite or S inputs pass
through the jack panel assembly with the exception of the DV input/output.
The Tuner/FL Control CPU instructs an input selector based on user settings and
sends the audio and video analog signals to the AV-codec IC .
This AV-codec IC will take the analog audio and video input signals convert them
to a digital DVD format and interface with the DVD-R/RW drive or the Hard Disk
for recording.
In normal recording mode the video output signal from the AV-codec IC is basically
a direct loop through the processing IC.
DV input/output record and playback line enter the AV-codec IC from the DV jack
assembly. An audio sampling rate converter (SRC) is used to convert all incoming
DV audio to 48kh
z.
