There is only so much bandwidth to work with, and the EPG might be the first to go so other nonsense features fit in what's left in the carrier signal after the visual programming gets crammed in there. If that happened it would kill one of the big draws of an OTA DVR, further driving viewers toward streaming.
You're both right. The intent is, your antenna will be hooked to what the 3.0 boosters call a "router," which will resemble a SiliconDust HDHomeRun network tuner, or (if it has DVR capability) a Tablo, AirTV, or Amazon Recast network DVR. Your TV(s) will then stream from the "router." This is meant to make it easy to integrate interactive features and targeted ads from the Internet with the content received by the antenna.
That said, there's no reason the tuner, er, "router" can't be built into a TV, so your antenna cable can hit that TV, then other TVs can "stream" from that one. There's also no reason you can't have more than one "router" on your home network; if every TV in your home has one, there'd be no need to stream any content aside from those interactive features and targeted ads. In that case, a multi-TV home may look pretty traditional, with coaxial cables running from an antenna through a splitter to each TV.
But Greasemonkey made a good point I hadn't thought of before. If your TVs, DVRs, and other "routers" are all expected
to be hooked to the Internet, why bother with PSIP?
My only comment is that the issue isn't bandwidth. Even a detailed, 21-day EPG with graphical thumbnails for each show would require a minuscule fraction of the data rate that a single HD (let alone 4K) video broadcast takes. Broadcasters may claim they need to dispense with PSIP "to serve man" - er, I mean "to save bandwidth" - but that should be recognized as a lame cover for their true motive: Profit! Just force everyone to get their EPGs from the Internet (for a fee, of course), making the idea of going "off the grid" (and avoiding those targeted ads) that much less attractive.
