5.3.4.3.Setting the Horizontal Phase of the Output Video – 525 Line Video
Video
525 H Phase Offset
0 to 1715
0
With this control, you can set the horizontal timing of the output video with
respect to the NTSC input when operating with a 525 line video output.
Setting this control to 0 keeps the output video in time with the input video.
Increasing the value will delay the output video in one-sample increments.
In order to advance the horizontal timing of the output video set the control
to 1716 minus the number of samples that you wish to advance the output
video. (E.g. to advance the output video 5 samples set the value to 1711.)
When increasing the
H Phase Offset
value causes it to go beyond the limit
of the line buffer, the
H Phase Offset
will wrap to the beginning of the line
buffer, resulting in a change of one line of throughput delay between the HD
input and the video output. See Table 3 for the minimum and maximum
delays possible.
5.3.4.4.Setting the Vertical Phase of the Output Video – 625 Line Video
Video
625 V Phase Offset
0 to 624
0
With this control, you can set the vertical timing of the output video with
respect to the PAL input when operating in a 625 line video output. Setting
this control to 0 keeps the output video in time with the input video.
Increasing the value will delay the output video in one-line increments. In
order to advance the output video set the control to 625 minus the number
of lines that you wish to advance the output video. (E.g. to advance the
output video 5 lines set the value to 620.) When increasing the
V Phase Offset
value causes it to go beyond the limit of the frame buffer,
the
V Phase Offset
will wrap to the beginning of the frame buffer, resulting in
a change of one frame of throughput delay between the HD input and the
video output. See Table 3 for the minimum and maximum delays possible.
5.3.4.5.Setting the Horizontal Phase of the Output Video – 625 Line Video
Video
625 H phase Offset
0 to 1727
0
With this control, you can set the horizontal timing of the output video with
respect to the PAL input when operating with a 625 line video output.
Setting this control to 0 keeps the output video in time with the input video.
Increasing the value will delay the output video in one-sample increments.
In order to advance the horizontal timing of the output video set the control
to 1728 minus the number of samples that you wish to advance the output
video. (E.g. to advance the output video 5 samples set the value to 1723.)
When increasing the
H Phase Offset
value causes it to go beyond the limit
of the line buffer, the
H Phase Offset
will wrap to the beginning of the line
buffer, resulting in a change of one line of throughput delay between the HD
input and the video output. See Table 3 for the minimum and maximum
delays possible.
5.4. CONFIGURING THE OUTPUT PICTURE
The
Output Picture
menus are used to configure parameters associated with the output picture. These
menu items are not applicable when a standard definition input video is connected. The chart below
