Using the Equipment
DECODE ERROR
If DVB subtitles are enabled but there are no DVB subtitles present in the transport
stream for the selected service then a DECODE ERROR alarm is raised.
A DECODE ERROR alarm is also raised if an attempt is made to decode an object
with a zero width. This can occur if subtitle recovery is enabled and the source of the
subtitles is transcoded from SCTE-27. In this situation the object data may have a
ragged right edge which prevents correct operation of the recovery mechanism. To
clear the alarm, disable subtitle recovery.
