Working with DSKs
Notes
• When you set a transition type, it is set within the Imagestore 750. Other panels attached to the
Imagestore 750 can detect, and use, its transition type.
• The transition type in the current Imagestore 750 might not be represented on your panel. In
that case, all transition type buttons on your panel will be disabled.
Changing Transition Rates
To change the rate of the A/B mixer, follow these steps:
1 From the main menu, press an ‘A/B Mixer’ button to access the ‘A/B Mixer’ menu.
2 Use the keypad or knob proxy adjacent to the slow, medium, or fast value to change the value.
The new rate is immediately available for use.
To change a DSK rate, follow these steps:
1 From the main menu, press a DSK button or press a ‘DSK Browser’ menu button to access a
‘DSK Browser’ menu.
2 Use the keypad or knob proxy adjacent to the slow, medium, or fast value to change the value.
The new rate is immediately available for use.
3 Repeat steps 1 and 2 to change the transition rates for other DSKs.
No further action is required to use the new transition rate(s). A new rate remains active until you
enter another rate.
Working with DSKs
Imagestore 750s used in the master control system provide 4 DSKs (downstream keyers). A key is
a video effect that usually consists of two video sources, fill and key. The keyer mixes the fill,
masked by the key, with upstream program video. In some cases, key values are derived from the
luminance of the key’s fill values. A key can be partially or fully opaque. It is possible for an oper-
ator to control the way the key values mask the fill values.
The Imagestore 750 performs video effects in a configurable order:
DSK 1 is upstream of DSK 2, which is upstream of DSK 3, which is in turn upstream of DSK 4.
The DVE (if present) can be placed before DSK 1, before DSK 2, or before DSK 3.
The effects to the right have visual priority over effects to the left. We say the effects to the right are
downstream and effects to the left are upstream. Your panel’s effect buttons, if any, might occur in
any order. Your panel might not have buttons for all video effects.
S
In an Imagestore 750 configuration, some or all DSKs can be disabled.
Keys can be external or internal. The Imagestore 750 supports up to 3 external key sources. Internal
keys are generally called clips, stills, or animations. The number of internal keys is potentially large
and is limited only by available memory.
The use of DSKs is affected by certain transition options. See
more information.
