With this control, you can set the horizontal timing of the output video with
respect to the PAL genlock reference input when operating with a 625 line
video output. Setting this control to 0 keeps the output video in time with the
Genlock reference.
Increasing the value will delay the output video in one-sample increments.
In order to advance the horizontal timing of the output video with respect to
the genlock 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 7
and Table 8 for the minimum and maximum delays possible.
With this control, you can set offset between colour frame A of the NTSC
reference and colour frame A of the NTSC analog output video.
Setting this control to 0 aligns the colour frame A of the output video with
colour frame A on the Genlock reference. Increasing the value will delay
the output colour frame A in one-frame increments.
Selects the aspect ratio of the output picture.
