There supposedly is a dual-feed for TWC viewers that have cable in an area that severe weather is occurring, but what about the many viewers that have satellite? Since those customers don't see local STARs unlike cable subscribers, I assume they're unable to receive the severe weather coverage. This dual-feed system definitely has some big flaws.
Not only do they need to have cable, but they need to have access to an IntelliStar and hope that the IntelliStar is properly configured to receive the proper dual feed signal.
You're right - the dual feed has serious issues. I have no idea what the proportion is, but it would be interesting to know what percentage of TWC's viewers watch on satellite, or subscribe to a cable company that doesn't have Stars to begin with (is AT&T's one of them?), or have a Star that isn't an IntelliStar.
I can understand the rationale behind the dual feed: relevant breaking weather information gets sent to those who need to watch it while everyone else isn't "interrupted" with news about what isn't happening to them. That said, there are actually plenty of people watching TWC who want to see news about severe weather, regardless of where it's happening. And, given the very strict technical requirements for successfully getting a dual feed to the right audience, there are certainly plenty of people in an area receiving a dual feed at any given time who just aren't able to watch it, period.
DirecTV and Dish might as well use the IntelliStar severe weather feed nationally more often (even if your area isn't affected by severe weather). Because that Dish's "master headend" is in Colorado and DirecTV's is in California, that is one of the only downsides of watching TWC on satellite since both satellite providers are only capable of beaming the satellite signal from outer space and back down to Earth to each one of their subscribers that have their satellites installed.
In fact, that was one of the main reasons why Dish previously dropped them for four days back in May 2010 (besides the retransmission fee increase, plus the failed "Flick & a Forecast" campaign and other longform programing). That's also what DirecTV did earlier this year until April (also having to do with both retransmission fee increases and longform programing). Either way, neither satellite providers are capable of providing with their own
localized IS/IS2 or even
localized EAS alerts whenever severe weather occurs in your area. Ironically, I once saw a "local" EAS alert on DirecTV that came all the way down in Los Angeles. Yet, I don't even live down there and other DirecTV subscribers outside of L.A. could of seen that same EAS nationally too. Dish also could of done it if a local Denver-based EAS would of happened and also of their subscribers could of seen it nationally too (except DirecTV of course).
Either way, neither satellite provider is prefect when it comes to TWC or even EAS alerts.
