25-Seven Launches TVC-15 Broadcast Watermark Analyzer & Monitor
CLEVELAND, OH – 7 March 2017
The Telos Alliance®—leader in broadcast radio and TV technology and parent company to Telos®, Omnia®, Axia®, 25-Seven®, Linear Acoustic®, and Minnetonka™—announced today that it has launched a new product, the 25-Seven TVC-15 Broadcast Watermark Analyzer & Monitor.
Think of TVC-15 as a modulation monitor for watermarking. For the first time ever, stations in electronically measured markets can independently detect, monitor, and analyze how well each element in their programming supports audio watermarking. Measurements happen in real time, right off the air, without being connected to a watermark encoder. Every 400 milliseconds, TVC-15’s tone verification codec detects and analyzes the actual code symbols in any audio you feed it, whether yours, or any other encoding station in your market. Standard analog inputs mean you can monitor any source, live or recorded. A front-panel graph of your station’s watermark density gives you a granular, moment-by-moment display; you can also download reports to look at encoding quality over hours, days and weeks. With TVC-15, stations now have a tool to independently verify the presence and relative quality of watermark tones embedded in their programming.
"Broadcasting is a numbers business. Broadcasters' success depends on what kind of audience they attract and hold, and we all know there’s a direct link between ratings and a station’s revenue in electronically measured markets," says Geoff Steadman, founder of 25-Seven Systems. "Having comprehensive tools—ones that help you understand the entire watermarking ecosystem—is essential to your station’s competitive picture. When we introduced Voltair two years ago, users asked if we could detect watermarks right off air, or at any patch point. With TVC-15, now we can provide a complete, end-to-end picture of your and your competitors’ encoding.”
TVC-15's proprietary algorithms constantly analyze the input signal, looking for valid code symbols that combine to create a station’s unique ID and time-stamp. The input can be any real-world source: your off-air signal (or a competitor’s), a test file from a production studio, an Internet stream, or even a live mic listening to a sample radio in a public space. If there are watermarks hidden in the audio, TVC-15 will report their details.
As an option for stations with a Voltair watermark monitor and processor, TVC-15 can also be utilized to automatically adjust enhancement levels in real-time. TVC-15’s Intelligent Adaptive Enhancement (AE) closes the feedback loop, letting broadcasters dynamically control Voltair processing based on moment-by-moment analysis of their actual air signal, pushing enhancement when it is needed, while backing off when not. This application allows Voltair users to better optimize the trade off between robust watermarking and clean audio.
