More About IP Codecs

NEW YORK — Last week’s article on IP codecs generated numerous emails. (In case you missed it, read that piece here.) The general gist of the emails is that these devices are not understood very well. Granted, they are still a fairly new technology, but they are a mystery. So, I’ll touch on several of the emails I received in hopes of clearing up some of the mystery.
The first note was from a station that is presently using an IP codec as an STL (Studio to Transmitter Link). When they moved their facility several years ago, they found they would not be able to make a microwave shot to the transmitter site, and the local phone company fouled up the program line installation they requested (big surprise). The station opted for the IP Codec route.
EAS LESSON: Protect Your Station
from Hackers

NEW YORK — By now, you have heard that there was an EAS hack at a TV station the other day. An alert went out about a zombie attack. Now, before anyone goes off about EAS, it should be noted that the CAP feed was not affected. This appears to be strictly a case of computer network security.
And before we go deeper, it should be stated that when something like this happens, it is only natural that it becomes a news story. And news stories require actualities. If something goes awry with EAS, please keep in mind that it is OK to play the actual audio message that went out – but it CANNOT contain the EAS data bursts or the two-tone alert signal. It is illegal to transmit those outside of an actual EAS activation or test, per FCC regulation 47 CFR 11.45.
