[EAS] EAS on Internet Streams

[ed.czarnecki at monroe-electronics.com]

Gary - to your first question...

Yes, I did this a few years ago as a lab test (streaming EAS tones and audio,  over the Internet, as well as via satellite and data broadcast streaming).  

As far as Internet streaming, there were a number of issues one needs to pay attention to.  One thing I recall vividly in one test was that the audio stream buffered again around 3/4 way through the alert - that caused it to time out longer than 2 minutes, so the audio portion of the message was cut off, with an awkward pause in the middle.  There are lots of potential reasons for that, including local LAN traffic, general Internet traffic & routing, the computer used for receiving the stream being low on resources, etc...

My question is, has anyone TRIED feeding EAS into a stream, and then hooking the stream output up to an EAS unit input and see if it decodes the EAS codes?

Does this even work? Reliably?

Does it depend on the streaming rate used?

I presume Internet monitoring would not qualify with the FCC to meet Part 11 Monitoring Assignment rules? (but you are talking of it as just a better-than-nothing back-up?) Gary Timm
