Mediaproxy LogServer Adds Nielsen CBET for Radio Audience Measurement
Mediaproxy's LogServer now supports Nielsen CBET (Critical Band Encoding Technology) layer 1 watermarking, expanding on its existing Nielsen NAVE (Nielsen Audio Video Encoder) decoding capabilities. This enhancement allows Mediaproxy to extend its compliance monitoring into the radio market for audience research data. The company is one of the few compliance system manufacturers officially certified by Nielsen.
Key Takeaways
- Mediaproxy's LogServer now includes certified encoding/decoding for Nielsen's CBET layer 1 watermarks.
- CBET watermarking, introduced by Nielsen in 2015, facilitates audience research in the radio market using PPM devices.
- Mediaproxy is one of few compliance system manufacturers officially certified by Nielsen, also supporting its NAVE technology.
- CBET is used by Nielsen in the US and Numeris in Canada for ratings measurement.
Why It Matters
This update allows Mediaproxy to offer a more comprehensive compliance solution across both broadcast television and radio, integrating passive audience measurement data directly into its LogServer platform. For broadcasters and streaming providers, this means enhanced tools for compliance and a unified approach to audience measurement data collection, particularly as audio content evolves. The development signals a continued convergence in measurement technologies across different media types; watch for further integration of these watermarking capabilities into wider cross-platform analytics for a holistic view of consumption.
Additional Context
The integration of CBET by Mediaproxy (14 March 2023, via TV Technology and Broadcast Beat) continues a trend of measurement companies enhancing their watermarking solutions. Harmonic and NAGRA, for instance, have been working together on a 'watermarking-as-a-service' model for live sports streaming (per 4rfv.co.uk archives, August 2022). Nielsen itself has been innovating in broader measurement strategies, including a pilot program to better account for co-viewing to offer a more accurate picture of total television audiences (4rfv.co.uk, February 2026, though this seems to be a forward-looking date and might indicate an error in the source data). Additionally, Nielsen and Lionsgate expanded their partnership for combined measurement of FAST channels and digital networks (4rfv.co.uk, November 2025 – again, likely a future date). These efforts underscore the industry's focus on granular, multi-platform audience data, moving beyond traditional metrics to capture consumption across diverse content delivery methods.
