  • Page 9: Background And Overview

    Playing a commercial or promo? Our research indicates a sung jingle usually encodes better than a dry voice-over… even though the spoken words might be more important to the selling message. TVC-15 Installation and User’s Guide Version 2.0 • January 2018...
  • Page 10 You need to understand the entire electronic rating system. You need tools that can quickly and precisely measure how it works. And you need efficient ways to apply this knowledge so it can optimize your station’s product. That’s why we developed TVC-15. TVC-15 Installation and User’s Guide Version 2.0 • January 2018...

  • Page 11: Tvc-15 Benefits

    TVC-15 doesn’t pair to a specific encoder. It doesn’t even need to be connected to the encoder. All it needs is a signal that’s had watermarks applied.
  • Page 12 3 You’ll need a mic and preamp, but probably have plenty of those. 4 In fact, we use TVC-15 in our own labs while developing Omnia processing algorithms and evaluating presets. TVC-15 Installation and User’s Guide Version 2.0 • January 2018...
  • Page 13 And if you want, there’s a big benefit for Voltair users: TVC-15 can control your Voltair in real-time! TVC-15’s Intelligent Adaptive Enhancement [AE] closes the feedback loop. It lets TVC automatically and dynamically control how Voltair is processing your signal in real-time, based on moment-by-moment analysis of your actual air signal.

  • Page 14: About 25-Seven, Watermarking, And You

    Got a call-in guest on a very compressed cell phone? Airing a stopset with jingles, dry announce, and produced sweepers? Just feed TVC-15 your encoded air signal, and give it your Voltair’s network address. The two units will form a closed loop that continuously adjusts for real-world program conditions.

  • Page 15: Benefiting From Tvc-15

    TVC-15 lets you do the same thing for your encoding. TVC-15 doesn’t need an encoder. It can analyze any audio signal from a monitor receiver, or to a consumer radio tuned to your station—or to any other station using electronic ratings.
  • Page 16 Encoder it recognizes, and then displays that code whenever it sees watermarks from that Encoder. You can rename any encoder for convenience: Main, HD2, 103.5, or whatever else makes sense. TVC-15 Installation and User’s Guide Version 2.0 • January 2018...

  • Page 20 This is based on the actual Encoder ID that accompanied the last valid message, along with an optional display of the time stamp that accompanied it . Encoder IDs are arbitrary and set by the ratings agency, and don’t include a station’s call letters or frequency. So TVC-15 Encoder A Encoder B identifies them simply as , and so on.
  • Page 21 BACKGROUND AND OVERVIEW | 13 These different Noise-analysis techniques underscore an important distinction between Voltair and TVC-15: TVC is a high resolution analysis tool, and as such, its noise injection needs to be highly uniform over time. Voltair’s analysis tools are modeled over longer time averages, and can use more random “real world”...
  • Page 22 This graph shows the confidence level for complete messages during the past two minutes. A complete message consists of twelve individual code symbols in a valid pattern, so TVC-15 draws a new Confidence line every 400ms. The line height displays zero to 100% confidence, and its color provides a quick visual reference: n Dark green lines indicate 80% confidence or better.
  • Page 23 14 If you’ve recently changed these limits, the graph might still be showing old commands based on previous limits. http://suitable.dyndns.org:14080/index.html TVC-15 Installation and User’s Guide Version 2.0 • January 2018...
  • Page 24 Check the encoder setup instructions. Other user controls TVC-15 includes complete, flexible control over its operation. Clock and system settings, network access, how TVC controls a connected Voltair, and remote passwords can be set from the front panel. Most of these settings, along with maintenance and customization functions, are also available remotely using any web browser.

Connect it to your network Connect TVC-15’s RJ-45 Ethernet Network jack to an appropriate data network, via Cat5 cable or higher. This connection is used for AE control of a Voltair, to synchronize TVC with an NTP server, for browser-based remote control, for downloading data reports, and for maintenance.

    Enter the server name using alphanumeric control as described above. When you first enable NTP, TVC-15 sends a message to the server specified on the screen. Then it synchronizes with the server’s clock. The process takes slightly less than a minute.

  • Page 41: Adaptive Enhancement [Ae]

    So finding the “right” enhancement level has been as much art—or voodoo—as it is science. We invented TVC-15 to put more science into the equation. It reads actual watermark messages from real-world encoded audio. TVC analyzes the code symbols in an audio stream 150 times a minute—fast enough to catch any program changes—and reports the...
  • Page 42 And we gave TVC-15 the ability to constantly send this enhancement information to your Voltair. With TVC-15 and Voltair working together, enhancement never has to rely on guesswork.

  • Page 43: How Adaptive Enhancement "Thinks

    The fictional ever-vigilant operator from our analogy—the one who has one eye on TVC and one hand on Voltair—would have beads of sweat by now. TVC does it all, easily and reliably. TVC-15 Installation and User’s Guide Version 2.0 • January 2018...

  • Page 44: Ae Signal Path

    STLs and AoIP systems won’t introduce an error.) We’ve found that the best AE installations for non-delayed broadcasts have Voltair connected to the insert point of the airchain processor, and TVC-15 connected to an off-air monitor. The entire hookup looks like this: AEIdealNonDelayed.pdf...
  • Page 45 TVC does not have to be calibrated or matched to a specific Encoder. All it needs is a non- delayed balanced audio signal at nominal +4 dBu line level from the receiver or monitor feed, and a network data connection to Voltair.
