3Play responds to a number of AMP of commands received across a network connection from external
devices.
17.7.1 CONFIGURING AMP
3Play’s AMP support is not unlike the macro implementation just described, but AMP does not enjoy the
same ‘auto-magic’ communication configuration advantages. Thus you will generally need to configure
the external controller to communicate with 3Play by providing its IP address (which you can locate, for
example, by exiting to Windows and using the system Network and Sharing Center). You will also need to
configure the external control system to address one or both of 3Play’s A and B output channels.
In all likelihood, the developer of your external system will have documented AMP configuration and
usage, but the next section provides details of the 3Play implementation for your interest.
17.7.2 AMP SHORTCUTS
AMP commands sent to trigger native 3Play shortcut commands of the same sort used by the user
interface and Macro system. These shortcuts consist of two parts: a prefix that identifies the target 3Play
output channel (A or b); and a suffix constituting the command to be executed. The AMP instruction may
also include values, such as unique clip identifiers, similar to 3Play’s Clip IDs.
The supported prefixes are amp_vtr1 and amp_vtr2. These address 3Play’s Output A or B respectively.
Supported suffixes are listed in the following table:
Suffix Value Description
_loop bool Changes looping playback status for the playout channel.
If no value is specified then looping is toggled.
_play void Play at 1X speed
_stop void Stops playback
_query void Query returns a result (string) identifying the content
currently on output and stores it for a subsequent _cue
_cue String Populates a special playlist tab named EXT VTR with a clip
or playlist previously identified by a query. (If the value is
void, performs a ReCue operation.)
_eject void Clears the current EXT VTR content
