Configuring Nielsen Watermarking

The Nielsen watermark is an inaudible cue tone in the audio stream of the channel output

signal. In the USA and Canada, the Nielsen watermark is detected by devices that provide

information for television audience measuring.

Both Nielsen watermarking version 2 (N2) and version 4 (NW) are supported. Either format

can be inser

ted individually or both can be inserted simultaneously into the data stream.

Note: Unlike N2 watermarking, NW processing does not support the

overwriting of audio codes that are present in the stream before the

watermarking process begins. Instead, the watermark engine leaves

space for a second (and possibly a third) Final Distributor Service ID in the

program band.

To configure Nielsen Watermarking on audio output:

1 Open the Output Server 2 user interface for

the channel you want to configure, as

described in Accessing the Output Server 2 User Interface, on

page 31.

2Go to Co

nfiguration > Watermark tab.

3Check Enable W

atermarking On Audio Output.

The Nielsen Watermark Encoder Configuration panel appears.

4In the Audio Output Group field, enter the output group to which you want to apply

the watermark.

5In the P

rocess Type field, select one of the following:

• N2

• NW

• Bo

6In Ser

vice ID field, enter the Nielsen channel ID number.
