*End-of-Sale and End-of-Support Notification for Wegener Nielsen Audio Video Encoder (NAVE) IIC

WEGENER® '''NAVE IIc™''' Nielsen Audio Encoder is the first industry product to encode the Nielsen proprietary NAVE™ identification information into a compressed ATSC transport stream. Nielsen's proprietary audio watermarking was introduced as a way to identify and track program content for TV rating purposes. This technology plays a key role in Nielsen’s Active/Passive metering initiative because it is both transport and consumer electronics agnostic, surviving intact through the entire broadcast distribution process.

== Digital Program Distribution ==
As more and more television stations migrate their transmissions to the FCC’s mandated ATSC DTV service, new network distribution models are being deployed where program content is distributed in compressed ATSC format from the network origination source through the local network affiliate and then on to the consumer’s home. In these environments, ATSC stream multiplexers are employed by the affiliate TV stations to add local programming.

== Supporting Compressed Transport Streams ==
The WEGENER® NAVE IIc™ expands upon NMR’s audio coding capabilities by supporting the ability to code pre-compressed MPEG-2 transport streams. The WEGENER® NAVE IIc™ encoder will insert NMR data into MPEG-2 Multi-Program Transport Streams compliant with the US ATSC standard.
