9.5 Progressive Scan Board
The DVD963SA series offer progressive scan YUV outputs,
and the option to select the interlace YUV output
by a sliding switch on the board (selectable at the rear of the
player).

9.5.2 Progressive YUV
This creates a picture signal with double the scan lines of a
conventional interlaced picture, to create a noticeably sharper
and smoother image. It offers higher picture resolution and
eliminates virtually all motion artefacts. Even on large screens,
the progressive scan lines are barely noticeable and it reduces
picture flickering significant.
Two new IC's are used: the Faroudja FLI2310 Digital Video
Format Converter, and the Analog Devices ADV7300
Progressive Scan Video Encoder.
This board also offers the Digital Crystal Clear feature, which
allow you to fine-tune the following parameters:
• Gamma correction.
• Chroma and Luma delay.
• Sharpness.
• DCDi: to produce a smooth and natural looking image
without visible artifacts (like jagged edges).
• True life: brings out details in the picture, producing a more
life-like image.
9.6 Double SCART
This board consists of two SCART connectors and a SCART-
switch (item 7501, STV6410), which is controlled by I
2
C.
In a P50 player with double SCART connectors, video and
audio loop-through must be available. This loop-through is
controlled by the P50 commands, which are send via pin 10 of
the SCART connector. When the DVD player is in standby, the
loop-through is active. During standby, the display (slave)
processor is active (takes over the I
2
C-bus), and will manage
the P50 commands.
Note: The loop-through only functions when the DVD-player is
in standby (NOT in low power standby)
Figure 9-12 Loop-through set-up
The B component (from RGB) and the C component (from Y/
C) share the same pin on the SCART connector (pin 7).
Because the B-signal is an "up-stream" signal (towards the TV)
and the C-signal is a "down-stream" signal (towards the VCR),
this pin 7 must be a bi-directional pin. Because the STV6410
