All video output signals are output at BNC connectors. Each video output comprises
two BNC connectors, one marked 1 and the other one marked 2. The two connectors
carry the same signal.
The following video output signals are supported:
• 270 Mbit/s digital SDI, connector pair marked SDI OUT, 1 and 2
• Analog composite PAL or NTSC, connector pair marked COMPOSITE OUT 1
and 2
The S
provides a ghost cancellation reference signal (GCR) which may be
TELLAR
inserted in the composite output of the decoder. The S
stored VITS lines. These signals may be inserted in the composite output of the
decoder. Up to two VITS lines per field can be inserted in the composite output in the
decoder. For further information on VBI signals, see
systems,
in The Stellar MPEG-2 Decoder, p. 3.
The following table shows the possible video output formats for one single video
channel depending on which video output module is installed:

Up to two stereo channels can be output at the S
face you configure the output to be analog or digital AES/EBU. All audio output is
output at XLR female connectors. The following table shows the pin allocation for an
XLR connector.
