In this instance, the "broadband pipe" is the ATSC channel, so there's NO PROBLEM with coding efficiency. You have plenty of bandwidth within the WiFi network, assuming a reasonably up to date WiFi. Now, the box itself MAY recode the stream to H.264, if there are whatever licensing reasons to do this. But even if the indoor stream retains MPEG-2 compression, you can still fit maybe 6 ATSC multiplexes, at least, in a typical 802.11n WiFi. > 3.

I'd be surprised if MPEG-2 isn't already supported in accelerators, because that's all there was for a long time. http://www.erg.abdn.ac.uk/future-net/digital-video/mpeg2-dec.html In any event, once again, the box can always transcode to H.264, if that's really necessary. > NO BERT.

Work it out, so maybe you'll convince yourself. >> The crucial point being, it's just another MVPD. > > Nope. It's just a carriage utility.

Let's say Sinclair builds out this LTE infrastructure for the Baltimore market area. They may be the only "broadcaster" transmitting OTA TV signals in Baltimore, or perhaps there may be one other LTE TV net in that market. So, my guess is, the other content owners, now no longer "broadcasters," would either pay Sinclair for carriage (using ad revenues?), or Sinclair would pay them to carry their signals, and keep the ad revenue? Or some combination of this. This new utility is more labor intensive than the previous big sticks, though. So unless the ad revenues go up somehow, that extra cost will be covered by a subscription fee. *Very much* like the original CATV systems. And we all know what they morphed into. At this point, you HAVE to ask, what do CBS, Fox, ABC, etc. do to get their content on the air in Baltimore? If Sinclair owns the transmission infrastructure, then why would these congloms go to anyone other than Sinclair? So, the other "broadcasters" will be competing only for local news, weather, and whatever community events they cover.
