Configuring the HE4000
HE4000 Encoding System
5.1 Setting the Default Configuration
The HE4000 is configured with a set of default, DVB-compliant parameters before it is shipped
from the factory. This DVB configuration consists of a standard set of operating parameters that
allow the user to quickly and easily begin operations. When configured to the DVB default
settings, the HE4000:
•
Encodes both audio channels and the video channel at the default DVB rate.
•
Compresses the channels.
•
Includes the channels with a standard set of table information in the internal transport stream.
•
Does
not
include either of the Aux data channels in the transport stream.
•
Adds modulator settings
Modulation: QPSK
Code Rate: 5/6
Data Rate: 8448000
Frequency: 70Mhz / 140 MHz
The HE4000 should be operated using either the DVB default configuration unless site-specific
operations require a change to the default settings. If a change is required, modify only those
parameters meeting operational requirements.
When beginning operations use the DVB default configuration to ensure that the decoder is also
initialized to the appropriate defaults. If the HE4000 operating parameters are modified, ensure
that the decoder parameters are also modified to match the new HE4000 parameters.
Setting the HE4000 to the default DVB configuration will return it to the factory delivered
configuration with the exception that any user custom configurations are preserved.
