66.9.1 Overlay Graphic in ETX-G

ETX-G supports “Keying” modes to overlay graphics; there are two types of Keying, namely “Internal Keying” and “External Keying”.

• Internal Keying
  In Internal Keying mode, an external software or external stream will set the Blackmagic card to superimpose the graphics over the incoming signal, as illustrated in the image below.
  
  Etx-g_internal_keying
  
  Configure the following settings when adding graphic overlays using Internal Keying mode:
  
  • Set color space of the playlist to ARGB32.
  • Set the output resolution equal to the input resolution.
  • Make the frames transparent by setting a source object background to “transparent”.

• External Keying
  In external Keying mode, an external software or stream sets the Blackmagic card to generate video and key SDI signals; the Keying is made by an external keyer as a master switcher, as illustrated below.
  
  Etx-g_external_keying
  
  For External Keying mode, configure the following settings (similar to Internal Keying):
  
  • Set color space of the playlist to ARGB32.
  • Set the output resolution equal to the input resolution.
  • Make the frames transparent by setting a source object background to “transparent”.
