What the Decoder Does

The front-end DVB-SPI and ASI interfaces are used to present a transport
stream in the format required by the internal decoder circuitry.
The Decoder can be used to receive an input signal from a variety of
sources. No error correction is supported at the input of the unit; if it is to
receive signals via a telecom network, 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.
Multiple services on the transport stream
