Kayak HD — Installation and Service Manual

Section 2 — Installation

The three buttons on the upper right-hand side of the

Genlock

Menu affect

video timing. These buttons are primarily used by Engineering when
setting up the switcher.

The first button is located in the

Video Std.

data pad (shown as

HD Auto

Detect

in

Figure 40

). This button selects the Video Standard that you

want to use for the Kayak HD switcher. Press this button to display a
list of the possible video standards, including

HD Auto Detect

and

SD Auto

Detect

. Select the video standard you want to use for the switcher.

The second button is in the

SD Ref Inp.

data pad (shown as

Analog

in

Figure 40

). This button is used to select the SD (Standard Definition)

Reference source which can be either the SD Analog Reference or any
one of the serial digital video inputs to the switcher. The digital input
must match the video standard that the switcher is running (the one
you selected from the

Video Std.

data pad).

The third button is in the

HD Ref Inp.

data pad (shown as

Analog

in

Figure 40

). This button is used to select the HD (High Definition) Refer-

ence Input video source which can be either the HD Analog Reference
or any one of the serial digital video inputs to the switcher. The digital
input must match the video standard that the switcher is running (the
one you selected from the

Video Std.

data pad).

There are two displays showing the Current Standard and External Refer-
ence settings that have been selected for your switcher:

The currently selected video standard is reported in the

Current Std.

field

in the middle of the

Genlock

menu.

The incoming reference signal rate is reported in the

Ext. Ref.

field (to the

right of the

Current Std.

field).

If you are using

Auto Detect

the video standard you have selected persists

until a different video standard is detected and locked for use by the
switcher.

If the reference signal is temporarily lost, the Kayak system will continue
using the previous reference standard and a

NONE

status will be reported.

Note

The Kayak HD cannot support both SD and HD at the same time; you must
choose one mode or the other. If you change the mode from SD to HD (or
vice versa) then the Kayak HD hardware must reprogram itself to process the
change. This takes a minute, but you only have to do it when changing from
HD to SD, or from SD to HD.
