    Now that I guess we're through the 1080p/720p debate...

    :backtotop

    :(

    Well it's still not as far east as it has been, let's see what tomorrow brings. It definately will be doing some moving by the end of the week.

    I should just walk away from this thread and check back in on the morning of the 10th.

    It is true that 1080P cannot be broadcast over OTA channels. It would take approx. double the bandwidth to do so.

    MPEG-4 compression as a OTA broadcast standard is a long way off. That would require another round of FCC rulemaking, with all the tests, public notices, hearings etc. That ain't gonna happen with the digital transition already long delayed.

    Also the broadcasters have spent the last 9 years spending a ton of money doing their digital buildout and bearing the operating cost of both analog and digital facilities, for which they have not yet nor will they anytime soon recoup a penny of revenue. They naturaly would not be willing to invest yet again on encoders and transmitter exciters.

    Keep in mind that OTA broadcasting is a MASS market, and research shows that most viewers claim to be satisfied with the tv they are getting now, Analog standard def. (Egad!) Even though the demand for HiDef is rapidly increasing it will still be a while before the masses are clamoring for it. I have had the sad experience of demonstrating my home theater to some friends whose reaction was "gee that's nice, when it costs only a few hundred bucks I'll look into it".
    Also the broadcasters are currently shooting themselves in the feet by doing not near enough to promote Hi Def. Holy cow Batman!

    1080P at 24 frames per second is a preferred production format because it is the format that is best adaptable to conversion to most other formats. This gives the producer the flexibility to distribute their product for a variety of purposes. It transferrs directly to film, say for european distribution without the need for standards converters.

    :welcome_s to the forum, tonyn, but :backtotop please...

    Note that the movement this afternoon and last night is still from the TLEs from yesterday afternoon. Let's see what happens when the TLEs are updated a little later this morning. Hopefully things will change a wee bit. :)

    Cheers,
    John

    In its current orbit, the D10 is continuing to move west a little less than one degree per day, within a 5 degree range. It reaches its maximum west longitude at about 8:00 P.M. EDT each day. Without any changes to the orbit, it should be at 99.4 Degrees West today. It should reach 102.6 on August 9. Of course, since it is still not in a circular orbit, there are bound to be some adjustments in the next few days.

    (I don't mean to re-hijack the thread, but we need some clairty on this)

    Absolutely true. The difference between 720p/1080i is indiscerible by the human eye at anything approaching a reasonable viewing distance, assuming the same equipment and source material. The laws of optics and human anatomy still apply.

    1080p would be nice, I guess, but since we still don't have 720p/1080i as the broadcast standard (480i rules until the changeover), don't expect the public or the broadcasters to be willing to dump their new equipment anytime in the next 10-15 years. Most US households currently can't "see" any digital format and probably won't until forced. And this transition has taken nearly a decade from start to Feb 09.

    Another expensive upgrade just isn't going to be endorsed by anyone, except maybe the mfgrs.:lol:

    Can you imagine telling Joe that his new Chinese made LCD, which he just bought to accept 1080i and cost him more than his first car, will not accept the new 1080p format?

    No time soon, I am sure.

    Well, only if you mean 1080p60. There is plenty of 1080p24 or 1080p30 that is encapsulated in 1080i60 with 3:2 or 2:2 pulldown right now.

    Of course. Nobody is going to upgrade all of their gear to 1080p just to do 1080p24 or 1080p30.

    It is slowly moving West, even though it moves back East each day it is moving farther West and less East. They are still circularizing the orbit. It SHOULD be in the proper spot towards Thursday, since they requested to test starting on the 10th.

    Remember that while the n2yo.com site claims to offer "Real Time Satellite Tracking", the information isn't derived from real-time telemetry. It is based on a sophisticated function that projects the position of the satellite. As such, the numbers you see may change inexplicably one way or the other as the function is updated.

    That makes sense, as D* got FCC permission to start testing on D10 starting this Fri., Aug. 10.

    I hope the rumors are true that D* expects to be done testing by Labor Day Weekend.

    Spaceway 1 is supposed to end up at 102.885 to give D10 some room for testing... Spaceway has moving about .01 each day for the past few days...

    It should be at 102.885 tomorrow or Wednesday.

    First off, they are NOT RUMORS. This info is on the FCC filing as posted in the OP of this thread:
    http://svartifoss2.fcc.gov/servlet/ib.page.FetchAttachment?attachment_key=-130667

    And the date listed for insertion into permanent orbit is September 15th. The 2 week delay has to to with the 2 week delay of the launch.

    Are you saying that D* is sticking to the Sept. 15 date, even though they got permission to start testing a week earlier than on the said document? Is it possible that they might also seek permission to move D10 into it's permanent slot earlier (Say around Labor Day Weekend as rumored)?

    It is absolutely possible, and they would definitely be granted permission if they did ask.
