o
For the
-m
option, the “File evaluated” line should specify an HLS m3u8 index file
as shown in Figure 2.
o
For the
-r
option, the “File evaluated” line should be an mp4 file that has
embedded tags or an encrypted tag file such as a file extracted from a mobile-
device log running the Nielsen sample application.
o
For the
-t
option, the “File evaluated” line should refer to an MPEG-2 transport
stream.
o
For the
-d
option, the “File evaluated” line should refer to a set of MPEG-DASH
segments merged, in the correct order, into a single file.
o
For the
-df
option, the “File evaluated” line should hold the folder name, followed
by “MpegDash.txt.” Note that there is no file named “MpegDash.txt.” The name is
simply a placeholder. The folder name, however, should refer to the folder that
you named after the -df option.
o
For the
-dr
option, the “File evaluated” line should hold the base name (including
the folder name) of the segments that were processed. When stripped of the path
name, this base segment name should match the string that you entered on the
command-line after the -b option.
•
Check the “Duration” line to make certain that the PCM-to-ID3 SDK generated tags
for all of the watermarked content that it processed.
Note
The reported duration (in seconds) is calculated by subtracting the tag time of the first
decoded ID3 tag from the tag time of the last decoded ID3 tag.
If the beginning or the end of the processed file has no Nielsen watermarks, the
reported duration is less than the number of seconds of processed audio/video
content. Otherwise, the duration listed in the Summary Report header should be
within 20 seconds of the duration of the processed content.
•
Make certain that the reported breakout type matches the setting that you used when
you configured your application. Your application should always set the breakout
code to 0.
SID List
Description
The SID List identifies the PC (Program Content) and FD (Final Distributor) SIDs (source
identifiers) that Validator found in the ID3 tags in the analyzed content. Validator lists only
the SIDs that it associates with the PC or FD code. Due to bit errors during the decoding
process, invalid SIDs may appear in the SID List, but their counts are significantly less
than those of valid SIDs. SIDs with a “UK” (unknown) watermark level or distribution type
may not appear in this list at all, even if the same SID is later identified as a PC or FD
SID.
In the SID List in Figure 4, the valid FD SID is
9151
, and the valid PC SID is
9051
. In the
entire file, the level was incorrectly interpreted as PC instead of FD for five unique NAES
2 audio codes.
