I should have explain myself more

Devices like iphone, Android phones, Apple TV, Roku etc... "billions to develop"
Why add the complication of devices? If all of your terminal devices connect via Wi-fi, what purpose would something like a DECA adapter serve? What do you plan on using for a server to serve up streams those devices? For their part, DIRECTV uses RVU which requires a very special server running software that must be licensed on both the server and the clients.
Are you familiar with what goes into creating software for media servers and device apps?
Yes that's whats awesome. Think about having 4 SD-LNBF's you could be watching a TS stream via one of the units and have the other 3 blind-scanning using hardware based blind scan.
Are you going to create this hardware to do blind scanning in association with your SDR tuners? If you're going to use conventional tuner chips to do your blind scanning, how will your streaming server collect the results so it knows what is available?
I think you may be getting all gooey about hardware and completely forgetting the software side of things.
In fact it would allow you to watch more stuff. It's just the TS('s) streams you choice delivered over IP.
What software is it that will do this magic on the server? What about the clients?
Do you know of any apps other than VLC that can handle TS streams or are you envisioning some sort of tuner plug-in for VLC?
