Cause Code 8 - Excess glue frame
events – Glue frames prevent
macroblocking. Excess glue frame
events indicate that the associated
output port is receiving too much
data. When the MPEG engine in the
GQAM nears full output capacity, it
begins to selectively choose video
PIDs on which it will issue a "freeze
frame" code in the MPEG video
stream for that program and will
drop the video packets for that
session momentarily. This will
happen only for sessions in which
blue framing was enabled when the
sessions was created. If this alarm
occurs frequently, it is a signal that
the output QAM carrying that
session contains to much data
