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 4 Block Diagrams SIGNAL FLOW DEC SDRAM 64Mb ENC SDRAM 128Mb ATA SDRAM 256Mb Tuner & Line Input Recording 1394 Link DV-codec 1394 Phy.

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. 7 SIGNAL FLOW DEC SDRAM 64Mb ENC SDRAM 128Mb ATA SDRAM 256Mb Recording Preview Mode 1394 Link DV-codec 1394 Phy.

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. 9 BOARD LAYOUT LAYOUT TUNB ASSY REAR FAN TUNER FrontFront-end JCKB ASSY Power Supply Unit MAIN ASSY (under HDD) HDD 80GB (520H) 160GB (720H) FL FRJB ASSY FLKY ASSY 8mm space 420mm FRONT 10 59mm mm 69 Æ 59 Writer Unit ÆDRIVE ASSY R7 (520H) ÆDRIVE ASSY R7R (320) MAIN BOARD 1 Chip CODEC LSI (M65672WG) MAIN FUNCTIONS ・ 10bit*27MHz(1ch),8bit*27MHz(3ch) Video ADC ・ PAL/NTSC Decoder Process ・ 3-Dimensional YC Separation Æ 0.13μm、CMOS 6 Layers (6Cu) Gate Scale ・ Frame TBC Æ about 4 million gate (Except memory) ・ 3-Dimensional DNR Supply voltage ・ MPEG Video Encoder Æ Internal 1.2V, External 3.3V (Voltage-proof 5V) Package ・ Dolby Digital Consumer Encoder Æ 576pin PBGA ・ Graphics Engine (OSD, Scaling, Mixing) ・ MPEG Video Decoder ・ Audio Decoder (AC-3, MPEG) ・ PAL/NTSC Encoder ・ 10bit*54MHz(5ch) Video DAC ・ Progressive Conversion ・ Audio I/F ・ Drive I/F(ATA/ATAPI, 2ch) ・ Main CPU (32bit RISC, 54MHz) 11 MAIN BOARD DV Device 1.
