Nielsen watermarking is a feature used by Nielsen customers to insert watermark codes into the source audio. The watermark is inaudible to the human ear but can be detected by Nielsen monitoring devices for tracking and measurement purposes. Nielsen watermarking technology can be applied to various media streams, including linear TV broadcasts, video-on-demand (VOD) services, and live streams delivered over the Internet. The watermarking process involves embedding a unique code within the audio content, which allows Nielsen to track when and where that content is being viewed.
The current implementation of Nielsen Monitoring is based on SDK for Nielsen version 1.4. All 48Khz and 24Khz audio sources are monitored for the Nielsen (TS, OTT, NDI, 2110, 2022-6, CDI). The library produces results every 60 seconds. Light-monitored channels and SD sources are monitored in a longer interval or 3 minutes (i.e., monitored for one minute and not for the next 2 minutes).
Note Nielsen requires an additional license; please contact TAG support if you require a Nielsen License.
Please follow the steps below to configure the same.
Navigate to System → Devices. Double-click on the Device Management. In the Nielsen License HASH field, provide the hash for enabling Nielsen watermarking and click on save.
On the Device Management do a Soft Reset to enable Nielsen watermarking contents.
Once the soft reset is done, the Nielsen related events are available under Thresholds. Please refer to Nielsen for details about Nielsen events.
To view the contents that are Nielsen watermarked, go to Sources → Statistics on the MCM device that is monitored for Nielsen.
** From MCS version 1.2.0 onwards compatible with MCM 6.3.14 and above, Nielsen SID is available for multiple audio PID’s.
Nielsen Reference Configuration
The expected watermarks values template doesn’t scan during the scanning process. To set the template manually, Navigate to Sources → Configuration → Common → Miscellaneous tab. Specify the Nielsen Reference template.
The template is text based in the structure: N2FD=1234,NWPC=0x1111,CBL5=*
an * can be used as a wild card for a ‘don’t care' definition.
same watermark can be defined multiple times.
total list length can be 16 elements
value is text based.
** MCS version 1.2.0 onwards compatible with MCM 6.3.14 and above, Nielsen Reference can be configured for each audio PID’s seperately.
Configure Nielsen Reference per audio under Profiles tab.
