Optional SDI Interface
The GTM supports de-embedding and embedding audio from/to an SDI video feed.
The GTM can support speeds of 2.970Gb/s, 2.970/1.001Gb/s, 1.485Gb/s,
1.485/1.001Gb/s, and 270Mb/s and is compliant to SMPTE ST 425 (Level A and Level B),
SMPTE ST 424, SMPTE 292 and SMPTE ST 259-C.
The SDI input supports typical equalized length of Belden 1694A cable up to:
-
200m at 2.97Gb/s
-
280m at 1.485Gb/s
-
500m at 270Mb/s
With the SDI output capable of typically driving at least 800mV at 75Ohms.
De-embedding
The GTM can de-embed up to 8 channels of audio at 48kHz.
These audio channels can then be used to feed game audio to the game encoder. Mix
and panning controls are available in GlenController, see
Embedding
In accordance with SMPTE ST 272 and SMPTE ST 299, the GTM can embed 8 channels of
audio at 48kHz.
The GTM supports embedding device audio (such as the
user’s
microphone) onto the
SDI feed as well as passing through audio from SDI input to SDI output.
Mixing controls for the SDI interface are available in GlenController.
