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
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.
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.
sign. This parameter is used with the Time Offset Enable
