1.3.2 Input Connections

The Satellite Receiver interfaces directly to Low-Noise Block (LNB) and
accepts an intermediate frequency (IF) input in the band 950 - 2150 MHz
(L-band) for operation in the specified symbol-rate range (see Annex B,
Technical Specification). The unit can provide dc power and polarisation
switching to the LNB.

Introduction

1.3.3 What the Satellite Receiver Does

The Receiver can be tuned to a specified satellite channel frequency and
polarisation. The input is down-converted via a Low-Noise Block (LNB) to
provide an L-band input to the Receiver. The front-end tuning is
microprocessor controlled with a frequency synthesised local oscillator. A
software tuning and acquisition algorithm resolves translation errors
(mainly due to the LNB).

The signal is then passed to a demodulator that recovers the signal using
soft-decision decoding. The resulting stream is Reed-Solomon decoded and
descrambled to provide inputs to the Decoder circuit. The received channel
may contain multiple Services, therefore the Receiver’s demultiplexer is
configured to select a single video Service and other audio/data
components and present them at the output.

Introduction

1.4.2 What the Decoder Does

The ASI interface is used to present the Transport Stream in the format
required by the internal Decoder circuitry. At this point, the operation of
the unit is the same as the Satellite Receiver.

The Decoder can be used to receive an input signal from a Public Telecom
Network via a Network Adapter Unit (NAU). No error correction is
supported at the input of the unit so a level of Quality of Service should be
negotiated with the Telecom Network Provider.

The Decoder is configured to select a single video Service and other
audio/data components from the multiple Services on the incoming
Transport Stream and present them at the output.
