PTS
18 1444645043 155 9020
The PTS field reports the presentation timestamp of the metadata PES packet in
which the Nielsen ID3 tag was found. The PTS value, which is truncated to the
nearest second, should match the PTS of the last audio packet presented to the
PCM-to-ID3 SDK before the ID3 tag was packaged and released. If this value is not
set correctly, the Nielsen ID3 tags may fall out of sync with the audio stream and
result in improper crediting.
The PTS should advance at roughly the same rate as the tag time.
