Overview
All five models covered in this guide have the same basic construction, board layout
and electronic circuit design. Block diagrams shown will be of the DVR-520H-S and
DVR-65H-S. The adjustment and test mode sections will be the same for all models
with the exception of additional test modes for the hard drive models.
Basic differences in models from the DVR-520H-S & DVR-65H-S are as follows:
• DVR-320-S………..No hard drive.
• DVR-225-S & DVR-220-S………..No hard drive or DV in/out terminal.
All models listed use the (R-7) DVDR/RW writer drive

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 48khz.

Signal flow Record Preview Mode
In the normal viewing mode (non record) or recording modes the video signal passes
through the AV-codec IC on the main board with very little processing visible at the
monitor output.
If the user selects Preview Mode the video output at the monitor will show the
effects of all encoding, 3D Y/C separation, decoding and record mode settings.
This preview mode was designed to provide the user a way of viewing the record
quality prior to making a disc.
All models have the capability to select different recording quality based on time
from one to six hours.
