VBI signal Recovered from the TS
VITC Time coded data is recovered
from the transport stream signal
and inserted in the composite or
embedded in the SDI output.
IDS/VPS The IDS/VPS signal is recov-
ered from the transport stream
and inserted in the composite or
embedded in the SDI output.
GCR no
S optionally supports audio, VBI and EDH embedded in the SDI signal.
TELLAR
The S needs no external synchronization to the network or transport stream.
TELLAR
The S synchronizes to the encoder through the network or transport stream
TELLAR
signal. The video and audio signals are timed to the MPEG-2 specified program
clock reference (PCR) to synchronize the program components including VBI sig-
nals.
Alternatively the S can be set in a free running mode where it does not lock to
TELLAR
the PCR. This enables the S
TELLAR
PCRs which typically occurs when other equipment in the transmission link adjusts
the TS bit rate without restamping the PCR values.
