DVBT Transmitter
Identifier
Use this field to set the address identifying this transmitter. The value
0x0000
“broadcasts”
to all transmitters in the network.
Time Offset and Time Offset Enable
Use the
Time Offset
field to specify the offset of local time from UTC time before the
daylight saving time transition. The range is
-12:00
to
+12:00
(hours:minutes). Numbers
above
0
do not require a
+
sign. This parameter is used with the
Time Offset Enable
parameter.
Frequency Offset and Frequency Offset Enable
The value in the
Frequency Offset
field sets the amount of offset of the centre frequency
of the emitted DVB-T signal relative, to the centre frequency of the RF channel. This is
expressed in kHz.
Tx Power and Tx Power Enable
Use these parameter to set and enable the transmitter’s power effective radiated power in
decibels.
General
New Channel and New Channel Assigned
The
New Channel
parameter allocates a new channel for this multiplexer function;
New
Channel Assigned
indicates the index of the most recent channel that was allocated to
this multiplexer.
Standard
The SEL-MDX1 multiplexes the following output standards:
ASI-188-ACBR, CBR, and VBR
ASI-204-ACBR, CBR, and VBR
ASI-DVB-T and DVB-T-SFN
SMPTE 310M
The
ASI-188-CBR
and
ASI-204-CBR-
standards use Asynchronous Serial Interface (ASI) with
a constant bit rate. The downstream receiver must be explicitly configured to use either
188-byte, or 204-byte packets, as per this setting. The module reads packets out of its
buffer at a constant rate and inserts null transport stream packets to bring the
Output Rate
of the multiplexer up to the required value.
