Overview
The NWE-TS is a Nielsen Transport Stream Watermark Encoder. It accepts MPEG-2 Transport
Stream (TS) input, extracts and watermarks selected audio services, and then re-injects them into
the TS in place of the un-watermarked audio inputs.
The NWE-TS adds data to audio used to track a video program through many national
distribution systems. Typically, the signal is monitored as it is broadcast on all commercial
full-power United States television stations, although other stations, cable feeds, and households
can be monitored.
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, usually one per encoder. 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 audio portion of the NWE-TS uses the Nielsen Audio Encoding System (NAES) Nielsen
Watermarks (NW) 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.
Operator Interfaces
The NWE-TS can be accessed via the following interfaces:
• DashBoard Control System™ — This interface enables you to monitor and control
openGear Connect compatible devices from a computer. Refer to the DashBoard User
Manual for details on using DashBoard.
• NWE-TS Network Configuration menu system— This interface enables you to setup
network communications for your NWE-TS directly from the NWE-TS chassis. Refer to
the section “
Manual Setup ” on page 2-12 for details.
Features
The NWE-TS was designed with the following client requirements in mind:
• Supports an ATSC Transport Stream carried in a DVB-ASI signal
• Ability to watermark up to ten audio streams
• Two levels of bypass for optimal protection from signal, power, and system failures:
› relays controlled by power and front-panel push buttons; and
› “soft” bypass under watchdog, software, and user control
• Reports status and configuration remotely via the DashBoard Control System™
• Reports serial number and IP address on the front panel
• Remote monitoring with IPMI (refer to the Dell® documentation for details)
• 3-year transferable warranty
