that player is currently stopped, it will jump to the last recorded picture and
pause.
EJECT: if the player channel is not yet in E2E mode when the command is sent, it
will return to E2E mode on its default record train (similar to receiving a REC
command). If the player channel is already in E2E mode, it will switch to the next
recorder channel available (AÆ BÆ CÆ …Æ AÆ …). This is for example useful with
a BVE edit controller to allow the editor to select the record train he wants to work
with.
Louth VDCP Protocol
This protocol is a more complex protocol mainly used by automation systems but
also by video switchers. It is based on Louth VDCP protocol standard, and can
handle clips as well as playlists.
AVSP Protocol
AVSP is a proprietary serial protocol giving quite full access to XT server
resources:
• simultaneous multi-port control from one serial link @115kbps.
• dynamic channel configuration including mixed channel for effect (audio and/or
video)
• playlist management including train (record in progress) with or without fixed
delay
• start/stop mode and GPI conditional events
• slow-motion clips
• extended channel and clip status reporting
• ganged channels control
• duplication or move of clips among network XT servers
• auto-backup to XFile
• metadata management (1 name + 3 keywords of 12 bytes each)
• This protocol is used for other EVS products interfaced to the server, like
AIRBOX, AIREDIT, EDIT2AIR and by third-party partners for specific
applications.
