cast. Once the event list is created and loaded into a DDR channel, taking
the channel to air will play the current clip and taking the channel off air
will cue up the next one.
When building event lists for fast paced shows, there may be no time to cue
up the next clip on the same channel after the current one has run. In this
case, splitting the rundown between event lists for two playout channels
may be desirable. This may create management issues if the rundown order
changes close to air. An alternative way to handle the situation is to load the
same event list into two channels and use one as the primary playout
channel and the second as a backup that can be cued to the next clip when
back to back events with zero cue time occur
Event List News Rundown Suggestions
News programs often have last minute rundown changes. The Event List
menu allows rapid manipulation of an event list while on-air.
• Event List clips can be played in random order. With
Auto Load
on,
touching a clip in the Event List immediately loads that clip for play-
back. When that clip finishes, the next one in the list loads normally.
• Clips in an event list can be reordered quickly. The
Move Up
and
Move Down
buttons allow a story to be selected and moved to a new loca-
tion in the list. For example, if the next two stories need to be exchanged
in playout order, selecting the next story loads it so it can be played
immediately, then while that story is playing pressing
Move Up
reorders
the list so the skipped story will be loaded next.
• Dumping a story can be done with Delete , however it is usually better to
move abandoned stories to the end of the list just in case.
• Adding a story is simply an Insert operation.
Router Interface Operation
Introduction
The Karrera system can interface with an external routing system. A
routing system connects a
router source (router input) to a router destination
(router output). Changing the router source sends a different signal to the
destination (called a
take ). A router destination can in turn be connected to
a Karrera input and be configured as a routed Karrera source (called switcher
source in this discussion and in the Karrera menus). The router acts as a pre-
selector for the switcher source, and so increases the number of inputs
available to a button on a Karrera system bus (
Figure 80 ).
