No I didn't say that. I'm EXPLAINING as to why many people don't notice the difference in HD quality. A 17 Mbps HD broadcast and a 12 Mbps broadcast is going to look the same on a old 480i SDTV. stations know the demographics of thier viewers and if they see most viewers are using SDTV and if adding a subchanel or 2 will add revenue then they'll take the money and run. Now once you get a majority of viewers watching via HDTV and complaining about picture quality will you might see things change.
More and more people are moving to HDTV, slowly, then they too will notice a difference in quality
yes and in 5-8 years most will notice. Just not now.
I don't know where you're getting that number from. ATSC actually supports 999 sub channels. A broadcaster could have a dozen 1080i sub channels if they wanted to.
Sure but a broadcaster only has 19 Mbps to spread around. A dozen 1080i subchannels would be about 1.5 Mbps for each channel. Now 480i looks crappy at 1.5 Mbps I can't imagine what 1080i would look like at that bitrate. You complain that your HD picture already looks crappy and that crappy signal is at least 10 Mbps so why you claim a station could have a dozen 1080i subchannels is weird. Below 12 Mbps a 1080i broadcast really starts to suffer. If you have a larger( 50" + ) HDTV you'll notice it at even at 14 Mbps. Realistically a broadcaster could have one 720p and one 480i/480p subchannel and both be very good quality.
And how many TV's have tuners that support MPEG-4? How many OTA set top boxes do?
right now, none. Once these tuners get into TVs and those TVs get bought in massive numbers this technology can really be useful. Of course that's 10-12year out at least.
And believe me its possible for MPEG-4 channels to look like garbage, ask any Dish Network subscriber.
Dish Network. Nuff said.
Look I would love to be able to drop the middle man (Dish Network in my case) for a system where there are a reasonable number of channels thru the air. But its just not going to happen anytime soon.
I never said it would happen overnight
