Overview
The NWE-IP is a fully compliant SMPTE ST2110-30 Nielsen Watermark encoder that will add watermark
information to track a video program through many national distribution systems. The information that is encoded
is used to uniquely identify the content of the creative and, if desired, track the transport path of the creative through
any other point in the distribution system that does watermarking. This patented ability to add information at
various stages is called multi-level encoding.
The encoded information typically consists of:
•
Source Identification Number (SID)
— A unique number is assigned to each source of creative.
Post-production facilities that serve more than one Automated Measurement of Lineups (AMOL) client may use
a separate SID for each client.
•
Date/Time
— The local time that the creative was encoded. The NWE-IP uses the Nielsen Audio Encoding
System (NAES), Nielsen Watermarks (NW) and Critical Band Encoding Technology (CBET) audio encoder.
Audio is encoded on a continuous basis. The data is embedded in an audio signal by performing minor
modification of selected spectral frequency components of successive blocks of audio data.
