Chapter 3: Configuration <strong>and</strong> <strong>Operation</strong><br />
Four frame synchronized outputs of the input video <strong>and</strong> four scaled<br />
outputs are available in this mode. The frame synchronizer <strong>and</strong> the<br />
scalar processor are on separate paths. This makes it possible for you to<br />
configure the XHD6801+ as an independent four-output frame<br />
synchronizer <strong>and</strong> a four-output up/cross/downconverter. The following<br />
special features <strong>and</strong> limitations apply to this video processing mode:<br />
• The input video st<strong>and</strong>ard control for the frame synchronizer in<br />
effect also controls the output video st<strong>and</strong>ard of the frame<br />
synchronizer.<br />
• The output video st<strong>and</strong>ard of the scalar is selectable through the<br />
scalar output video st<strong>and</strong>ard control (Video > Output > Output<br />
Video St<strong>and</strong>ard Select). However, the video format of the frame<br />
synchronizer outputs is controlled by the frame synchronizer input<br />
video st<strong>and</strong>ard control.<br />
• Two independent sets of horizontal <strong>and</strong> vertical phasing controls<br />
are available to both video frame synchronizer <strong>and</strong> scalar processor<br />
(Video > Processing > Synchronizer). This makes it possible for<br />
you to adjust the phasing of the frame-synchronized outputs <strong>and</strong> the<br />
scalar outputs independently with respect to the reference.<br />
• The LOV parameter (Video > Output > Primary LOV Mode)<br />
controls the behavior of both the frame synchronizer outputs <strong>and</strong><br />
the scalar processor outputs.<br />
• Since the scalar processor resides on a path different than the frame<br />
synchronizer, the frame delay induced by the frame synchronizer<br />
will not be added to the scalar processing path <strong>and</strong> therefore the<br />
maximum frame delay through the scalar processing path is limited<br />
to two frames (the amount of propagation delay through the scalar<br />
processor). This setting is available in Audio > Other> I/O Delay<br />
Configuration. Also, there are some problems on the scalar<br />
processor when h<strong>and</strong>ling “dirty” video input. Without the frame<br />
synchronizer acting as a filter at the scalar video input, the scalar<br />
outputs may not be perfectly clean when there are glitches at the<br />
input video (for example, when the video format is changed).<br />
