9.5.10 Progressive Scan
Description
The progressive scan part is integrated in the Digital Board and
built around the SAGE Fli2200 de-interlacer / line doubler
(7701). This I2C controlled de-interlacer uses a 64Mbit SDRAM
(32bit x 2M) to perform high quality deinterlacing (meshing).
The de-interlacer gets his digital YUV input data from the
STi5508 (7200). The format of the digital YUV input to the
SAGE is CCIR656 with separated Hsync, Vsync and odd/even
signal running on 27Mhz.
Because the STi5508 doesn't have a Vsync output the odd/
even output of this IC has to be translated to a Vsync signal.
Some glue logic has been added to extract the vertical sync.
The glue logic circuit consists of Flip-Flop IC 74HC74D (7701)
and EXOR 74LVC86 (7702). The next diagram shows how the
vertical sync is extracted.

Figure 9-2
The output of the de-interlacer (4:4:4 progressive video) is fed
to the Analog Devices ADV71967 MacroVision compliant
DENC (7801).
The YUV current output of the DENC is fed via a low pass filter
to the single supply output opamps AD8061/8062 (7802-7803).
The analog video is fed via a 7 poled flex to the analog board
where the YUV 2FH cinch connectors are located.

Short Description of the Module:
The DVIO Module is a decoder for DV streams. The module is
intended for the Philips DVDR1000/002 en DVDR1000/172
DVD+RW recorders. Input is a stream from a DV-camcorder
IEEE1394. Outputs are CCIR656 Video and Analog audio
(L+R). A serial control interface is present.
The following picture shows the location of the DVIO Module
inside the DVDR set.
