Affichage Image
L'affichage Image décodera également les informations du timecode RP-188 HD et VITC SD, à partir
du signal d'entrée vidéo SDI, et l'affichera sur le côté droit de l'affichage. Si les informations du
timecode sont correctes, vérifiez votre périphérique pour vous assurer qu'il achemine le signal de
timecode approprié encodé en tant que VITC ou RP188.
En conclusion, le standard vidéo est affiché sur le côté gauche de l'affichage Image pour vous
assurer que vous contrôlez le bon flux vidéo.

Blackmagic Video Device Embedded Control Protocol
Version 1.0
If you are a software developer you can use the Video Device Embedded Control Protocol to
construct devices that integrate with our products. Here at Blackmagic Design our approach is
to open up our protocols and we eagerly look forward to seeing what you come up with!
Overview
The Video Device Embedded Control Protocol is used by ATEM switchers to provide Camera
Control functionality with supported Blackmagic Design cameras. Please refer to the
'ATEM Software Control' chapter, 'camera control' section of this manual, or the ATEM Switchers
SDK manual for more information. The ATEM Switchers SDK manual can be downloaded at
www.blackmagicdesign.com/fr/support.
This document describes an extensible protocol for sending a uni-directional stream of small
control messages embedded in the non-active picture region of a digital video stream. The
video stream containing the protocol stream may be broadcast to a number of devices. Device
addressing is used to allow the sender to specify which device each message is directed to.
Assumptions
Alignment and padding constraints are explicitly described in the protocol document. Bit fields
are packed from LSB first. Message groups, individual messages and command headers are
defined as, and can be assumed to be, 32 bit aligned.
