Protocols

4.1 PROTOCOL OVERVIEW

These protocols allow the XT[2] server to be controlled by external devices.

Sony BVW75 Protocol

This protocol allows the server to be seen as a VTR by the controlling device. On

a playback channel, all usual transport commands (play, PlayVar, pause, goto

timecode, pause, stop, etc…) are supported. On a record channel, only Rec and

Stop commands are supported.

This protocol is the simplest one but does not support clip management. It should

be used when the controlling device does not support the XtenDD35, Odetics or

Louth VDCP protocols (ex: edit controllers, NLE applications, some video

switchers, VTR controllers, etc.)

XtenDD35 Protocol

This protocol is based on the Sony BVW75 protocol for all standard transport

commands. It has extended commands so that it supports clip management: using

this protocol, the controlling device can create, name, recall and delete clips.

This protocol can be used with Thomson/GVG XtenDD range of switchers, and with

DNF ST300-EVS and 4040CL-EVS controllers.

Odetics Protocol

This protocol is based on the Sony BVW75 protocol for all standard transport

commands. It has extended commands so that it supports clip and playlist

management: using this protocol, the controlling device can create, name, recall

and delete clips, but it can also manage playlists.

This protocol can be used with many different control devices and automations

software, including DNF ST300 and 4040CL controllers.
