Perhaps the MediaFlo guys/gals can answer. Is local content insertion (...whatever that means to you...) a possibility? And if so....


Well perhaps I don't understand the MediaFlo "physical" and "transport" layers. If you have a 'seamless' "NATIONWIDE" service, how can you 'do' different bits in different parts of the country? Not saying you can't 'do' different bits, I am implying that at some point there has to be a 'break' (or is that BRAKE??? ;-) ) in the service. You can not 'mesh' the bitstream with different contents (at least in no way that I know...), or can you?

Thanks in advance...

have a clue, or they haven't considered the broadcaster's opportunity costs.)

"Local interest" has an even more distant connection to local.

P.S. By the way, at least two Qualcomm (and I assume MediaFlo) engineers if not 
executives are on this list.  I believe I've even met one face-to-face 
(although I didn't let on that I 'knew.')

50 national and 15 local services that will deliver ~20 minutes of content per day to receiver cache.
What does local mean?
Really? The effective resolution of NTSC is 320 x 240 at 60 fields per second. With good de-interlacing, I would suggest that these streams will come close to equaling NTSC quality, however, that is irrelevant since we are talking about displays in handsets. Apple started the iTunes video service at this resolution, and the stuff looks fine when output to an interlaced TV. But the LPTV guys could deliver something like 640 x 480 @ 60P which would be significantly higher quality than NTSC, perhaps with a 320 x 240 base layer.
NTSC is 'effectively' 320 x 240? Really?

This argument must be tempered with reality. People are consuming vast amounts of video content via the Internet, most of which is less than NTSC quality. It is all driven by applications and competition. Mobile Tv does not need to equal the family room viewing experience.
Very true...
