Over the past few decades, we've migrated from handling a single channel of content using composite video and analog audio pairs, to elaborate multi-channel facilities routing HD video with embedded audio over SDI or in many cases discrete AES pairs. These audio signals are often a mix of 5.1 and stereo programs and in many cases encoded to or decoded from Dolby® at some point in the chain.

With TVC-15, radio stations in electronically measured markets can now monitor how each element in their programming supports audio watermarking. Measurements happen in real time, without the need of a watermark encoder. Every 400 milliseconds, TVC-15 detects watermarks in any audio you feed it. This could be your own station's audio, or that of a competing station in your market. You can monitor any source, live or recorded.

Forgotten by many, but not all, are the soundscapes of the past; both technological and natural in origin. If you've worked in radio long enough, you already know something about changing soundscapes. The clattering of a [teletype machine](https://www.youtube.com/watch?v=FWa6u5_Itvs) in the newsroom, the sound of records and reel tapes being cued and the once per second chunk-chunk-chunk of the Western Union master clock as it counts down the time remaining till the next hourly newscast, are all gone but not forgotten.

It’s no accident that AoIP is taking radio and TV by storm: the economies of scale, ease of use, and return on investment are undeniable. Traditional POTS and ISDN phone services are steadily being supplanted by SIP- and VoIP-based methods at the service-provider level. ISDN is already unavailable for many new installations, and POTS is moving that way now. A SIP/VoIP phone system offers digital phone services that cost less, sound better, and are more easily managed than traditional services.

In one extreme, the control room may have been a dream for jocks to operate, but a nightmare for techs to service. Too far the other way, and you had a setup that could be easily serviced, but required an octopus to operate. Most were a compromise (although some would be better termed a stalemate).
