Yes, I pay for Sprint PCS Vision, but to get unlimited internet at maybe 500-700 kbps, not for TV. A few TV channels like CNN then come free and others can be subscribed, though I don't. Nor do I really watch CNN on my phone, but I can.
And my Sprint HTC Mogul phone has 2.8" diagonal screen with a 240x320 (or 320x240) resolution. Like the iphone it can be switchably viewed in either portrait or landscape mode but is not a wide screen aspect ratio like M/H recommends.
I'm not claiming my phone is the neatest thing since slice bread but definitely do believe the mobile phone services will compete with M/H for low bandwidth video, offering a base line that must be matched.
BTW, I've always liked math and been rather good at it. Take that as you will. ;-)

It's always interesting to see what people come away with when they are exposed to new things. Tom, do you actually pay for Sprint PCS Vision? If so, that's funny. You don't' get 30fps video in 16:9 with that phone, Tom. And, you only get pre-digested clips. As for the iPhone, Craig and I went into that a few days back. You see, the iPhone screen is taller than it is wide, Tom. It's 240 wide. And, Tom, a "single screen" handset here is wider than high. And, it's 240 high, and 416 wide. Are the numbers hurting your head? But, it will be possible to stack the video with other video, or map presentations, or other data, so that you can have two video sources on -- say -- a suitably-equipped iPhone, stacked one atop another. The video size is appropriate even in the rear seat of a car, but it might be just a bit ofa stretch.Did you note the part about the possibility of having SVC (scalable video coding) in a pay sub-channel, with the main video free? In other words, it's possible, bandwidth willing, to offer enhanced video, and even to charge for it! Indeed, with proper business and technical arrangements, it might even be possible to have enhanced video (SVC) offered on say a MediaFlo type network, and the lower-resolution video on M/H. I could say more, but much of the early, basic considerations, including "system requirements" have not been made public, and will probably never be made public. I'll go out on a limb and say that with M/H it will be technically possible to, say, drive up I-95 and have the same "service" on your screen continuously usable, despite shifting from transmitter to service to service area, and back again. It's all in the metadata ... I strongly doubt that your 2" wide phone screen presents as much as 240 pixels, and it certainly doesn't present 416 pixels. The three screen heights is for "home viewing" and not too many people will want to watch m/h content at home, where higher resolution screens are available. It will be very difficult to present M/H content in the same transport stream with HD content, at least if there is much motion in the HD content. However, there are several ways of provisioning this service, and Ion Networks for one has indicated that they will be interested in talking to other broadcasters about providing some of their content in an M/Hbroadcast.Only time will tell. Also, there are several ways to charge or not charge for this content. The point is that your Sprint phone cannot offer you network or local content on a day and date basis. M/H can do just that. If you want to watch pre-digested clip casts and pay for the privilege, you are free to do that, but you don't pay for cable tv, right? That's why I doubt you make much use of Sprint PCS vision. PEOPLE DON'T WATCH TECHNOLOGY, they watch content. Ubiquity is the word here -- and "don't miss a second." What you were exposed to in this presentation is a technology that broadcasters can use to repurpose (most of) their existing content to a new arena, at a cost of less than $300k. You were also exposed to at least one hand-held receiver that would support DVB-H, ATSC M/H, MediaFLO, etc in a single unit, with -- ahem -- a unified Electronic Service Guide. You were also exposed for the first time to a rich media environment (OMA-RME for traffic maps, and eventually location-based presentations. One that ALSO works across all the above media platforms. What you talk about is the "chimp" of Sprint PCS Vision (a unicast, not broadcast) system, and screen size. You are lucky if your 2" phone even has 120 pixels across, Tom. 120 pixels across a 2" screen is 60 pixels per inch. Which is a fairly high dot pitch. It's simply math, but Barbie says "Math is hard."

I'm not sure 240p will be enough even for mobile. It has to compete with what I can get already as part of my Sprint PCS Vision plan and is I think already less than the rez of an iphone.Supposedly at a viewing distance of 3 screen heights the sweet spot for human vision is about 1080p. I guess I view my 2" high phone screen (sideways) at maybe 8 screen heights viewing distance so it would peak out at about a resolution of 1080p * 3/8, or about 405 lines even for that very small screen. I'm guessing even smart phones will soon have an average resolution of above 240p.But maybe a free advertising supported mobile simulcast of the network HD broadcast could still be viable. ??- Tom John Willkie wrote:----------------------------------------------------------------------http://www.oab.org/cffm/custom/PDFs/Jay%20Adrick%20presentation.pdfwhich tends to open the tent door quite a bit .John WillkieYou can UNSUBSCRIBE from the OpenDTV list in two ways: - Using the UNSUBSCRIBE command in your user configuration settings atFreeLists.org- By sending a message to: opendtv-request@xxxxxxxxxxxxx with the word unsubscribe in the subject line.----------------------------------------------------------------------You can UNSUBSCRIBE from the OpenDTV list in two ways:- Using the UNSUBSCRIBE command in your user configuration settings at FreeLists.org- By sending a message to: opendtv-request@xxxxxxxxxxxxx with the word unsubscribe in the subject line.
