3. Scanning Line Conversion Function
LN DAT (address 6x) and MD DAT (address 7x) are data which indicate scanning line conversion coefficients.
There are the following 8 conversion coefficients:
1.67/1.75/2/2.22/2.33/2.67/2.8 = K
K =
The conversion coefficient equals the ratio of one scanning line to scan lines generated by interpolation. The
coefficient can be changed on the screen.
In the WIDE-ZOOM mode, compression and expansion on the screen can be changed by combining these 8
coefficients as desired.
Compression and expansion are carried out by setting the coefficient and the number of switching lines.
The upper 6 MD DAT bits (bits 3 to 8) provide coefficient data.
The lower 2 MD DAT bits (bits 1 and 2) and 8 LN DAT bits provide line number data.
The coefficients and corresponding MD DAT are shown below.

The interpolation coefficient 2.0 has two modes which are determined by the value of bit 3.
When bit 3 is 1, an interpolation line is generated by outputting the same signal as that of the
preceding line. This mode realizes images with a higher vertical resolution.
When bit 3 is 0, an interpolation line is output by averaging signals of the preceding and following
lines. This mode realizes images with smoother diagonal lines.
4. DA Converter Clock
RYCK and BYCK, which are YCK halved and phase inverted, are output as D/A converter clocks.
5. Output Control
A black signal is output when BLNK is high.
number of scanning lines of output signal
number of scanning lines of input signal
