Controlling Xplay devices using automation protocols
5. Set the P ROTOCOL Settings:
K EYERS Specify the keyers (layers) of a particular device that the Evertz protocol will
control. These keyers must be configured in advance in Xplay using the
Device Manager (see
“Adding and connecting Xplay to playout devices” on
page 2-8 ).
Since there is no keyer specified by the Evertz protocol, the Evertz driver in
Xplay will decide where to put the next element and does this by looking for
the first of the configured keyers that has nothing cued nor on air. If every
available keyer has something on air then Xplay will select the first keyer
that does not have any element cued.
Note: If a template is loaded onto a keyer external to the protocol, the Evertz
protocol driver has no knowledge of this and therefore will incorrectly
consider this keyer as an available keyer.
V ERIFY M ULTIPLE To reduce the number of verification calls made to the Xmedia Server, the
Evertz protocol may send a verify request for a particular element multiple
times in rapid succession (once a second, for example). This value sets a
throttle on the number of incoming Evertz requests for an item that result in
a call to the XMS. Xplay will reply with a cached value for that item on every
verify request for the item until the number of repeat request received is
equal to the Verify Multiple value. The recommended value for this setting
is 5.
Note that for playlists, verify only verifies that the playlist exists on the
Xmedia Server – it does not verify that all the playlist content is published
on a device.
P LAYLIST ID R ANGE Specify an inclusive range if you want to cue and take playlists via the Evertz
protocol. The range can be either numeric or alphanumeric, although
currently playlists do not fully support Recall IDs so the lookup of a playlist
will always by name.
When an element is identified to be within the playlist range, a cue
command opens the playlist and puts Xplay in Automatic playout mode. The
playlist is then played out on the Take command and play out ceases when
a Clear command is received.
I GNORE P LAYLIST C LEAR This setting is used in conjunction with the P LAYLIST ID R ANGE setting that
allows you to cue and take playlists via the Evertz protocol.
Since a Clear command from the Evertz protocol stops the playlist from
playing out abruptly, enabling this setting allows Xplay to ignore the Clear
commands, thereby letting the playlist to finish on its own.
