④ User marker coordinates
・In the "DATA (X Y)" column, the coordinates for
S：START POINT and E：END POINT of the
currently set user markers are displayed.
without such settings, the "—" marker appears.
・Move the cursor to the X/Y data. Using the ENT
switch, new user markers can be drawn or
already registered user markers can be modified.
・The setting can be made in 1-pixel increments.
The top left of the effective screen serves as the
reference point (0001, 0001) of the coordinates.
From this point, the coordinates can be adjusted
in the pixel range of 1920 x 1080.
・Default setting is —(unregistered).
●Resetting the data
・With the "DATA (X Y)" settings blinking in
magenta, hold down the
righthand button on the mouse) longer than 3
seconds, and the preset data may be deleted (—).
●Coordinate reference point
This panel has 1200 vertical pixels. In the
broadcast format, 60 lines of non-picture area is
created each at the top and the bottom. Markers
cannot be displayed in this non-picture area.
Therefore, the X-Y coordinate of the effective
screen starts at the reference point (0001, 0001)
as shown below.

●Marker lines and coordinate values
There are 2 line widths for the user markers.
However, the coordinate for the start point and
that for the end point are different by 1 pixel.
「スタートポイント」が示す座標のピクセル位置
Pixel position in the coordinate for the "start point"
ライン幅：2ピクセル
Line width: 2 pixels
Pixel position in the coordinate for the "end point"
Accordingly, in drawing a horizontal line, the
Ydirection address has a coordinate value with 1
pixel added, as shown below.
「スタートポイント」が示す座標のピクセル位置（Ｘ、Ｙ）
Pixel position (X, Y) in the coordinate for the "start point"
Pixel position (X+a, Y+1) in the coordinate for the "end point" 「エンドポイント」が示す座標のピクセル位置（Ｘ+ａ、Ｙ+1）
When a vertical line is drawn, the X-axis address
has a coordinate value with 1 pixel added, as
shown below.
「スタートポイント」が示す座標のピクセル位置（Ｘ、Ｙ）
Pixel position (X, Y) in the coordinate for the
"start point"
ａ
「エンドポイント」が示す座標のピクセル位置（Ｘ+1、Ｙ+ａ）
Pixel position (X+a, Y+1) in the coordinate for the
"end point"
