The NWE-3G is the ideal solution for inserting Nielsen Watermarks into the audio for television programming. The time stamp structured watermarks make use of the "SID" (Source Identifier), 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 Gbit/s, 1.5 Gbit/s, or 270 Mbit/s) and 4 AES3 digital audio inputs. It applies the watermark to up to 16 PCM audio channels selected from the 16 embedded and 8 AES channels. The watermarked audio is embedded into the SDI output and 8 of the 16 channels can be routed to the 4 AES outputs. The module can be configured to support a variety of audio configurations, 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.
