How do they encode your digital audio and video to identify the source without making it audibly or visually apparent?
Niels Thorwirth of Verimatrix will present an overview of content identification, recognition and marking technologies used as a data carrier or forensic tool with a deep dive into one implementation of digital watermarking.
Join us Wednesday, September 19th at 12 noon at iHeartMedia, 9660 Granite Ridge Drive, San Diego. We’ll serve a free lunch, followed by the presentation.

On August 29, 2018, the FCC granted a Construction Permit for Christyahna Broadcasting to build a 500 W day/night AM station on the 1400 kHz “graveyard” channel in Lemon Grove. The daytime pattern location is in the middle of the old KSDO tower site. The evening pattern location is at a residence on Berry Street in Lemon Grove.
Accompanying the CP is an application to operate a translator on 93.7 MHz from Mt. San Miguel with 4 watts vertical aimed northeast toward El Cajon and Santee.
According to Wikipedia, Christyahna principal Gerry Turro was past Chief Engineer at WNEW New York, then the operator of the famous “Jukebox Radio” network WJUX in northern New Jersey. The FCC eventually broke up the network of low power FM stations in 2003 after it was accused by competitors of improperly extending its coverage with translators outside its primary coverage area using fiber links to the various transmitters. Turro built KRLY-LP in Alpine, California, but transferred it in 2005.

After KPBS-TV abandoned channel 15 during the digital conversion in June 2009, the FCC allocated that spectrum to first responders in the Los Angeles and Orange Country for use in mobile 2-way voice communications, otherwise known as “T-band” public service spectrum. Past UHF-TV channels 14, 16, and 20 are also so designated in the L.A. metro area.
According to TV Technology magazine, satellite relay provider SES has offered to reimburse C-band dish owners for the cost of registering their earth stations with the FCC. The only catch is…you have to have procrastinated till at least July 28, 2018, to be eligible. Get more information by contacting FCCregistration@ses.com. The NAB encourages members to register all C-band earth station dishes by October 17, 2018 to ensure that they are eligible for protection going forward.
The reason the industry is asking broadcasters to register receive-only dishes is that the FCC is proposing to reassign C-band terrestrial receive frequencies to the telecom industry. If you maintain a receive antenna for radio or TV network services, this could present an interference problem. As users register, the FCC can get a better idea on how large the impact would be.
If you need assistance with your C-band dish registration, Signal Wiz in San Diego can file your application.
KPBS-TV atop Mt. San Miguel tackled their antenna work last week as part of their TV spectrum repack project. They must move from UHF channel 30 to channel 19 while KSWB-TV moves from channel 19 to 26 and KNSD (TV) from 40 to 17. These full-power TV stations, all in Phase 2 of the FCC Broadcast Incentive Auction, must switch to the new channel alignment by April 12, 2019.
