As always, I disagree on the "back channel." This would take away two of the biggest advantages of OTA broadcast: simplicity and scalability. And as we saw with the RAI "interactive" channel, so far anyway, it does not depend on any such return channel. Instead, you tune to the subchannel, wait some, and then you get the "interactive" info stored in your STB. So interactivity stops at the STB. They will provide phone numbers or URLs, if you need real interactivity. Just move over to the telephone or PC and get interactive. (I'd like to know how successful that has proven, in the test markets.) Others have commented on the economics. My only addition would be that the only way for such a scheme to pay for itself is for advertizers to pay a meaningful premium to broadcasters, for the privilege of having their ads directed. This could be done in a one-way broadcast, but only with a small number of ad options. And you don't need any form of IP encapsulation either, unless you want it for snob appeal. With or without "back channel," the broadcasters would have to figure out how to get the new-design STBs or integrated receivers out to customers. It would take another FCC mandate. The NAB doesn't seem to have much clout with the CE vendors. And I would expect that the MVPDs would oppose any such NAB attempt strenuously, for instance, which in turn would make the broadcasters quickly back off. Same objections to this would also exist in the MVPD nets, if more customers would resist having proprietary STBs installed in their homes. If customers don't resist, such boxes could be designed for the MVPDs, who will in turn take the additional ad revenue and charge the marginal extra cost of the boxes back to the customers, via the monthly fee. Will the customers be given the option, or will they be graced with these boxes no matter what?
