You can bias TVC’s measurements using statistical noise simulation. Or you can feed TVC from a microphone pointed to any radio or loudspeaker, in a quiet test room or noisy public space. You can equalize or distort the signal going to TVC to simulate low-quality radios. TVC is switchable between endcoding formats: Layer 1 (used for US radio) and Layer 2 (Canada and some other countries). Use any convenient analog source, and get an instant reading of how strong its codes are. Or to an Internet radio, a HD receiver, or any other way listeners are getting a signal with watermarking codes. TVC-15 doesn’t depend on a particular encoder, and doesn’t have to be connected to it.
It keeps counting, and changes color to alert you to the condition. Each time you do, the timer resets and appropriate message details are displayed.ĭuring periods of low masking (silence, spoken word, some music), the timer doesn’t get as many chances to reset. Under ideal circumstances1, TVC decodes a complete message every 4.8 seconds.

It takes 4.8 seconds for the watermark system to assemble enough code symbols for full station identification. That’s fast enough to track individual program elements, or style changes in a song, or even the difference between a host and a call-in guest.Ī front panel timer updates every time your station broadcasts a complete watermark message.
The symbols that make up a complete station identification message are then processed through our proprietary algorithms.Ī front panel graph of your station’s watermark reliability updates every 400 milliseconds. Raw symbol reliability is displayed on a constantly changing bar. TVC-15 Watermark Analyzer & Monitor Overview Every 400 milliseconds - 150 times per minute - TVC-15’s tone verification codec analyzes the actual code symbols in any audio you feed it.
