About remote control protocols
This section provides information for using remote control protocols to operate K2 Summit/Solo
systems. It is intended for use by installers, system integrators, and other persons responsible for
setting up automation systems at a customer site.
For information about configuring AppCenter to enable protocol control of a K2 channel, refer to
topics in "K2 AppCenter User Manual".
Using AMP protocol to control K2 systems
Advanced Media Protocol (AMP) is an extension of the Odetics protocol.
AMP commands are available via Ethernet or RS-422 serial ports.
The automation setting for preroll should be at least 10 frames.
Preroll is 1 second for mixed compression format playout. Preroll is 10 frames for same compression
format playout.
The AMP's socket interface uses IANA assigned port number 3811 for TCP.
In AppCenter, you must set a channel’s options to enable protocol control of the channel.
Subsequently, when the K2 Summit/Solo system starts up, the channel is immediately available for
protocol control. Manual log on is not required.
For channels in gang mode, the protocol must connect to the lowest numbered channel in the gang.
This is required to support jog/shuttle of ganged channels.
AMP Two-Head Player Model
The AMP protocol supports the use of a two-head player model in that two clips can be loaded for
playout, as follows:
•
Current clip — The AMP “preset id” is the active clip.
•
Preview clip — The AMP “preview preset id” is the preview clip. The preview clip becomes the
current clip and begins playing when the current clip completes. When controlling AMP in Auto
mode, the “in preset” (and “out preset”) command should be sent before the Preview in commands.
Related specifications are as follows:
•
A 3D/Video+Key player channel does not support a two-head player model.
Controlling transfers with AMP
Remote control automation applications can initiate transfers via AMP. The AMP command must
be sent to the K2 Summit/Solo system, not the K2 Media Server. This applies to both stand-alone
and shared storage K2 systems.
If using AMP to initiate transfers between K2 systems and Profile XP systems, you must send the
AMP command to the K2 system, not the Profile XP system. Transfers (both push and pull) are
