9.5Progressive 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).

9.5.2Progressive 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.

This board consists of two SCART connectors and a SCART- switch (item 7501, STV6410), which is controlled by I2C.

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 I2C-bus), and will manage the P50 commands.

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
