Nielsen Watermarks Encoder
NWE-3G Nielsen Watermarks Encoder
Rear Module Sufx (ex: [model]-R2)
-R2 Rear Module for NWE-3G
Advanced Audio Processing
• 3GHz video path with bypass relay protection
• Handles all popular SD and HD video formats, up to
1080p/59.97
• 4 AES-3id paths with bypass relay protection
• Transparent to VANC and HVANC data
• Both video and audio are delayed by one video frame
time (two frames for 59.97Hz progressive formats)
• Up to 5 NWE-3G modules can be installed in a single
2RU frame; alternatively, 1 NWE-3G can be installed
with up to 16 other cards
• RS232 port for external / automation control and
monitoring
• DashBoard control with selectable alarming
on video, audio and time inputs
• 5-year transferable warranty
The NWE-3G is the ideal solution for inserting Nielsen Watermarks into the audio for television programming.
The timestamp structured watermarks make use of the “SID” (Source Identier), which is a serial number
used by Nielsen and the television industry to uniquely identify program content, to ensure proper crediting
of viewing.
The NWE-3G accepts an SDI input (3 Gb/s, 1.5 Gb/s, or 270 Mb/s) and 4 AES-3id digital audio inputs. It
applies the watermark to up to 16 PCM audio channels selected from the 16 embedded and 8 AES channels.
Embedded audio signals that are watermarked are re-embedded into the same location in the SDI output.
AES audio signals that are watermarked are re-encoded into the same AES output.
The module can be congured to support a variety of audio congurations, from a single stereo pair up to two
5.1 surround groups plus two stereo pairs.
The NWE-3G includes a video frame delay to ensure proper audio-video synchronization. The companion rear
connector module provides relay bypass of the video and AES signals, allowing the NWE-3G module to be
inserted or extracted without interrupting the program path.
The timestamp included in the watermark data can be synchronized to either SMPTE 12M LTC (both
balanced and unbalanced inputs are provided) or network time obtained by the frame from an NTP server.
