Introduction
1.4 The Telco Receiver/Decoder
1.4.1 Typical Decoder System
The Decoder is a component of Ericsson’s range of equipment. It is designed for
use by broadcasters and distributors of video and audio Services. It can be used as
a Transport Stream monitor or to decode signals received over a
telecommunications network.

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.
