The NWE-TS is the ideal solution for inserting Nielsen Watermarks into the audio of television programming that is carried in an ATSC Transport Stream (TS). For watermarking uncompressed audio in SDI or AES3 signals, see the companion product NWE-3G.

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-TS accepts a DVB-ASI input, containing a 19.39 Mbps ATSC TS. It applies the watermark to up to 10 user-selected audio streams which can be 5.1-channel surround, stereo or mono. All watermarked audio streams are reinserted into the output TS with the same timing relative to the video as they had upon arrival at the NWE-TS input.

The NWE-TS can be configured to assign different SID values to each of the selected audio streams, making it suitable for use with both single-program and Multi-Program Transport Streams (MPTS).

The NWE-TS includes a TS delay buffer, to ensure proper audio-video synchronization. The ASI interface provides relay bypass, allowing the TS to pass transparently through the unit when power is off or bypass has been activated by the front-panel pushbutton.

The timestamp included in the watermark data can be synchronized to either SMPTE 12M unbalanced LTC or network time obtained via the network connection from an NTP server.
