Connecting the output signals

Video output 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

Inserting VBI signals The S

TELLAR

provides a ghost cancellation reference signal (GCR) which may be

inserted in the composite output of the decoder. The S

TELLAR

provides internally

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 VBI signals for PAL and NTSC

systems, in The Stellar MPEG-2 Decoder, p. 3.

Video output formats The following table shows the possible video output formats for one single video

channel depending on which video output module is installed:

Audio output Up to two stereo channels can be output at the S

TELLAR

decoders. In the user inter-

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.

Example: The analog audio outputs for audio channel 1 are connected to the

XLR connector pair marked AUDIO OUT 1, L and R. Single channel

Composite only The S

TELLAR

decoders detects the output format as PAL,

PAL-M or NTSC and configures the decoding process

accordingly.

Component only The S

TELLAR

decoders detects the output format as 525

lines or 625 lines and configures the decoding process

accordingly.

Composite and

Both formats, composite and component, are output on

their respective connectors.
