The SCN bit in the SCM register enables or disables scan conversion. When scan conversion is disabled
(SCN = 0), the input scan lines are interlaced at a field rate of 60 Hz for 525-line systems or 50 Hz for 625-line
systems. When scan conversion is enabled (SCN = 1), the input scan lines are non-interlaced at a frame
rate of 60 Hz or 50 Hz.
2.4
Scaling Processor
The scaling processor scales down the input image in both horizontal and vertical directions. In addition to
scaling, the scaling processor filters the image in the vertical direction and removes annoying flickers, which
are common when a computer-generated graphics or text, especially a static image, is displayed on TV. The
scaling processor uses a 3-tap adaptive filter, whose coefficients are dynamically adjusted on a line-by-line
basis to maintain optimal performance.
The scaling processor is enabled by setting the SCN register bit to 1. When scan conversion is enabled,
the data manager receives non-interlaced pixel data via the demand mode interface and passes pixel data
on to the scaling processor for overscan-compensation processing. The output of the scaling processor
feeds the video encoder core for encoding. See Section 2.5, Video Encoderfor a detailed description.
When the scaling processor is disabled, SCN reset to 0, the data manager receives pixel data via master
or slave mode and passes pixel data directly to the video encoder core, bypassing the scaling processor.
The scaling processor, when enabled, is controlled by the following registers: SPPL, DPPL, SLPF, and
DLPF. These registers define the size of the image before and after scaling. The SPPL register defines the
number of active pixels per line before scaling and the DPPL register defines the number of active pixels
per line after scaling. The SLPF register defines the number of active lines before scaling and the DLPF
register defines the number of active lines after scaling. Refer to Section 2.11, Register Descriptionsfor
additional information on these registers.
