first loop. These adaption functions are only available when playing transport-stream files.

Loop adaption for the Continuity Counter:

When selecting Continuity Counter StreamXpress will modify, in real time, after the 1

loop, the

Continuity Counter of each PID in the stream to ensure that there is no discontinuity in the count that

may result in decoder error or reset. As a result after the 1

loop, the continuity count of the original

file will not be maintained when that option is enabled.

Loop adaption for the PCR and DTS/PTS:

When selecting PCR, DTS/PTS StreamXpress will modify, in real time, after the 1

loop, the PCR

and DTS/PTS of each program/component in the stream to ensure that there is no discontinuity in

the PCR that may result in decoder error or reset. As a result after the 1

loop, the PCR and PTS/DTS

of the original file will not be maintained when this option is enabled.

NOTE: This option should be not used when testing time sensitive element like interactive data

triggered by PCR value or add insertion trigger with SCTE35 flags. As the PCR and PTS/DTS are

re-stamped, the trigger will be lost in these applications after the first loop.

Loop adaption for the TDT/TOT:

When selecting TDT/TOT StreamXpress will modify, in real time, after the 1

loop, the TDT and TOT

according to the setting below. It will re-stamp each packet with a TOT/TDT packet updating the

timetable so it appears to be continuous in time. There are 3 options for updating the TDT/TOT.

Do Not change the TDT/TOT time in first loop: In this case StreamXpress will use the TDT/TOT from

the original stream as reference and when looping will increment the TDT/TOT accordingly.

Use current date/time: In this case StreamXpress will discard the TDT/TOT from the stream and

replace it with the current time and date of the PC.

Change date/time to: In this case StreamXpress will use the specified date/time and replace the

TDT/TOT. Upon looping, the date and time will be updated accordingly.
