Revolutionizing Broadcast Workflows: Telestream's New Vantage Option for Nielsen C3/C7 Watermarking

May 12,2025

Introduction

The media industry is undergoing a rapid transformation, with broadcasters and content providers seeking faster, more efficient ways to monetize live and on-demand content. In a significant move to address these needs, Telestream has introduced a groundbreaking new feature for its Vantage media processing platform—automated Nielsen C3/C7 watermarking with reserved clip SID (Source Identifier). This innovation enables broadcasters to accelerate the delivery of VOD and OTT content, including ads, by seamlessly integrating Nielsen’s audience measurement technology into their workflows. The result? Faster monetization, improved efficiency, and maximized revenue potential.

Understanding Nielsen C3/C7 Watermarking and Its Importance

What Are C3 and C7 Windows?

In television advertising, C3 and C7 refer to the metrics used to measure commercial viewership:

C3: Measures ad views within 3 days of live airing

C7: Extends this window to 7 days

These metrics are crucial for advertising revenue, as they determine how much networks can charge for commercials based on delayed viewing (DVR, VOD, OTT).

The Role of Watermarking

Watermarking embeds invisible identifiers into content, allowing Nielsen to track:

When and where content is viewed

Ad exposure across platforms (linear TV, VOD, OTT)

Audience demographics for better ad targeting

Traditionally, applying these watermarks was a manual, time-consuming process—until now.
