Cleveland, OH (March 9, 2017)— 25-Seven Systems, part of the Telos Alliance, has launched a new product, the 25-Seven TVC-15 broadcast watermark analyzer and monitor.
Using the device, 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, off the air, without being connected to a watermark encoder.
Every 400 milliseconds, TVC-15’s tone verification codec detects and analyzes the code symbols in any audio fed to it. Standard analog inputs mean stations can monitor any source, live or recorded. A front-panel graph of a station’s watermark density provides a granular, moment-by-moment display. Users can download reports to look at encoding quality over hours, days and weeks.
Geoff Steadman, founder of 25-Seven Systems, explained, “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 algorithms 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: a station’s off-air signal (or a competitor’s), a test file from a production studio, an Internet stream, or a live mic listening to a sample radio in a public space. If there are watermarks hidden in the audio, the unit will report the details.
