AUDIO LOUDNESS MANAGEMENT

SPOTCHECK®

〉〉

TRANSPORT STREAM COMPLIANCE MONITOR

SpotCheck® provides easy to use, no-guesswork, automatic A/85
and EBU R128 loudness measurement and access to all audio
loudness records. Because SpotCheck® monitors an IP, ASI, or a trans-
mitted over-the-air MPEG stream at the transmit (emission) encode
point, SpotCheck® measures and logs loudness for all programming
emanating from the facility.

Programming thumbnails with date-time and as-run ID provide ready

correlation between loudness measurement records and programming

Clearly displayed session

loudness plot continuously

displayed for all programming.
Where loudness deviates from

dialnorm by more than 2 LU,

segment is highlighted.

On-screen mode selections including ATSC A/85 and EBU R128 measurement.

Instant selection of audio sub-programs.

Select plotting to show Dialnorm, True Peak, and/or

Loudness Envelop (min/max instantaneous LUFS)

Select spot segmenting to correlate to as-run data. Where as-run is not

available, programming can be segmented into regular user-selected Short or Long intervals.

Selecting a date on the Reports calendar shows a report

for the day, with segments grouped into loudness too

high, too low, or complying.
A list of segments is displayed, with direct correlation to

loudness, airtime, and as-run data for each spot or

segment. Reports can be set up to sort by loudness, time,

as-run code or other criteria.
Reports can be automatically e-mailed, triggered to send

at several severity level choices.

Segments can be searched using date – time with the intuitive display
of loudness plots along with date-time-stamped thumbnails of the ac-
tual corresponding programming, or can be queried and correlated with
the facility as-run automation list. SpotCheck® readily pinpoints any seg-
ments that are out of CALM A/85 or EBU R128 compliance, and con-
versely helps in documenting compliance should an erroneous complaint
appear.

Options allow even more transport stream/programming analysis. Option
QUALITYCHECK checks for the presence of CEA708/608 closed-cap-
tioning, as well as the string content text, and also can detect transport
communication errors as well as frozen/black frame and audio silence,
with Alert Manager sending these alerts to your designated personnel as
simple e-mails. Option AIRCHECK provides easily managed lo-res proxy
downloads of user-selected transport stream segments that can be sent
and viewed over e-mail to recipients with common smart devices and
media players.

Easy to use web user interface provides for easy setup and use. Requiring
no breakout from the MPEG stream and not affecting the emission stream
in any way, SpotCheck® provides an easily integrated, facility-based, su-
perior solution for loudness records and compliance verification.
