Flexible Digital Core

The ADV8003 has a flexible digital core, allowing multiple options for the routing of video data. This allows the user to place the OSD in
front of the video processing so the OSD will be overlaid on one or more outputs. Alternatively, video processing can be placed before the
OSD ensuring all outputs are processed to the highest quality. The digital core can also be configured so that the ADV8003 can output one
or all of the inputs in various arrangements, for example, picture in picture with one input appearing as a window within another or two
inputs routed to two outputs.
Several common modes of operation are defined to assist the user to quickly integrate the ADV8003 into a system. Refer to Section 2 for
more details.

Video Signal Processor

The motion adaptive de-interlacer in the ADV8003 offers excellent edge detection and ultra low angle performance. The per-pixel de-
interlacing algorithm used delivers excellent performance which can be seen with specialist test patterns, on facial features like eyebrows
or on shirt collars. This algorithm decides on whether an area of an image is moving or not and then applies the appropriate de-interlacing
approach accordingly. The de-interlacer can also determine when interlaced video originated as progressive and can reconstruct the
original frames.
The ADV8003 features dual scalers referred to as primary PVSP and SVSP. The PVSP uses a contour-based interpolation scaler which can
upscale from 480i to 4k x 2k. It can also arbitrarily up and down scale between 480i and 1080p. The advanced scaling algorithm used in
the ADV8003 eradicates many common problems associated with scaling video such as ringing and jagged or blurred edges. The SVSP
