First of all, we need to select the input through which the service is received and fill in the rest of the
required parameters.
3.2.2 Status of the output streams coming from DTV inputs (DTV Monitoring)
In the
Outputs
menu, we can find the module in charge of monitoring the output streaming quality,
which allows a quick check of the main channel quality indicators together with the errors found.
The 2 most significant parameters analyzed are:
•
Transport errors
: The input demodulator is unable to read the date packet, even if forward error
correction has been applied (Forward Error Correction or FEC). The packet is damaged and is
discarded.
•
Continuity errors
(TS discontinuities): the sequence indicator (continuity counter) allows the de-
coder to find out whether a transport packet was lost.
