SMART DVB Monitoring
SMART can inspect the contents of MPEG video and audio streams. Besides parsing and alerting on stream header information these services can also be checked for frozen or black video (tied to a tolerance level for noisy analog inputs further upstream) as well as for audio level and audio silence. For data components on these services (such as DVB subtitles) data freeze detection is available. These features are particularly useful to automatically identify issues in playout with severe intermediate transmission issues. This allows DVB transport stream monitoring on 24/7 base.
Content verification process can run in background, i.e. with no need for the verified service to be displayed.
