Characteristic Specification
power
Voltage 90-132 or 175-264 VAC auto-detect/selected
Frequency 60/50 Hz ± 2%
Consumption < 35 watts typical with full LNB DC load & QPSK receiver
Transport-In Options See Table 1.2: Transport-In Options on page 6.
Conditional Access
Wegener COMPEL  /CA Transport-level or by program
PIN Scrambling
Turnaround option to bypass scrambled
streams to ASI output (Contact factory)
Transport Demultiplexing
Aggregate MPEG Transport Rate 2.5 to 86.25 Mbps (55 Mbps in Release 1) if not limited by symbol-rate
limits of installed receiver card. This rate is guaranteed for reception
and transmission to ASI port only. For local decompression of audio
and video, the maximum transport rate remains 55 Mbps.
Number of Programs Unlimited
PSI Recognition Automatic

Stream Padding Minimum of one K28.5 null character padding in inter-byte gaps,
strategy after that is to add equal pad amounts between bytes before
adding extra padding between TS packets
Stream Processing (network-controlled) Program mapping (routing of incoming program content to up to 16
virtual programs at output) and/or conditional DPI filtering.
