I remember reading about this company (Telegent) which was making analog only tuners for cell phones. Perhaps someday, they can come up with something for ATSC, though broadcasters are trying a different approach (at an expense in terms of bandwidth of course).

There is nothing to kill - no one is watching NTSC TV on their phone. They might be watching on a portable TV, which will be a paperweight in 6 months.

The only hope for mobile TV is that chips for ATSC-M/H will be cheap enough to put into portables (phones and others).

It is ironic that an American company puts an NTSC/PAL/DVB chip into phones that other countries can use while neglecting our own system. More info on one of their chips:

For UHF at least, I have to think it is technically feasible to use the existing ATSC system for cell phones. It works for the laptop, but perhaps it's just too hard to hold a phone in one spot. Are Doppler effects from a few mph that hard to overcome? In strong signal areas, I can sometimes even pull a DTV signal at full speed on the freeway (with an On-Air GT).

Yes it would work but makers are not going into invest in something that's not more reliable. Plus on a portable you don't need the full HD signal - a much more scaled back, BW friendly signal would suffice - which I assume the new ATSC-M/H will do.

I suppose that is the main drawback of a system designed for HD. The connection has to support the entire channel, even if only 1mbps of data is actually needed at the time. I've wondered why SD/480i channels are just as hard to receive, but I hadn't thought about why until now.

In Japan, which according to the article has "tens of millions of viewers," 1 segment of the DTV stream is reserved for mobile TV. I suppose that is what we are trying to do with ATSC-M/H.
