NWE-3GA Nielsen® Watermarks Encoder


Nielsen® Watermarks Encoder

High quality insertion of Nielsen® Watermarks into embedded and / or AES3 digital audio.

The NWE-3GA is the ideal solution for inserting Nielsen® Watermarks into the audio for television programming. The timestamp 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-3GA accepts an SDI input (3 Gb/s, 1.5 Gb/s, or 270 Mb/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. 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 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-3GA 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-3GA 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.
