The object of this part of IEC 1079 is to define the conditions and methods of measurement to be applied to MAC/packet decoder units.
The specifications of the limit values of the various parameters of the decoder are outside the scope of this part.
This unit can either be connected to the output of a DBS tuner unit or be a part of it. The methods of measurement concerning the DBS tuner part are described in part 2
of IEC 1079.
The input signal is a baseband video signal encoded according to one of the following MAC standards:
- D-MAC/packet;
- D2 MAC/packet.
The output signals are:
- red, green, blue colour signals (R,G,B);
- one or more audio signal(s);
- the composite synchronization signal.
NOTE The methods of measurement can also be used for MAC/packet receivers with built-in MAC decoder units if R,G,B output signals are available.
