Field Explanation
Active Stream Displays Active Transport stream.
ASI Packet Status In non-hierarchy mode only the high priority (HP) input is used. In
hierarchy mode both high priority (HP) and low priority (LP) inputs are
used.
The DVB-T Packet Status sub window displays the status of parameters
for the four ASI input transport streams shown following:
ASI 1 HP: Primary input, high priority channel
ASI 1 LP: Primary input, low priority channel
ASI 2 HP: Auxiliary input, high priority channel
ASI 2 LP: Auxiliary input, low priority channel
ASI Input "OK" if input is present, "Error" if input missing.
ASI Uncorr(ected)
Error
ASI Uncorr(ected) Error displays "OK" if no errors are uncorrected,
"Error" if some packets had errors that could not be corrected by Reed-
Solomon error correction.
ASI Corrected Error ASI Corrected Error displays "OK" if no errors detected, "Error" if some
packets had errors that were corrected by Reed-Solomon error correction.
ASI Input Overflow ASI Input Overflow displays "OK" if input data rate OK. "Error" if input
data rate too high (FIFO overflow).
NIT Status NIT Status displays “NIT OK” if an NIT (Network Information Table)
packet is detected in input transport stream. If no NIT packets are
detected then “No NIT” will be displayed.
PCR Status PCR Status displays “PCR OK” if PCR (Program Clock Reference) has
been detected in transport stream. If no transport stream is present it will
display “No NIT”. If transport stream is present, but PCR is not present it
will display “No NIT”.
