    A lot of people have no idea how much storage uncompressed HD would require. I'm always amused when I see someone commenting about "uncompressed HD".

    Same with audio. You have to compress everything or you are going to have some major bandwidth taken up. Maybe he mean't lossless?

    I think he actually did mean uncompressed. That was a rumor for a while with the uninformed(no offense to him) and it has taken off. Its mainly just a lack of understanding about the whole subject

    rcoleman,

    No Kidding 1920x1080 that is 2 plus Million Pixels (picture Elements). Ok then, Video is 30 Frames per second although 1080 is interlaced so that is 15 Even Frames of about 1 Million Pixels, and 15 Frames of about another 1 Million Pixels. This equals about 30 Million Pixels per second in standard 1080i. Considering a Standard Over the Air Broadcast can only carry 18 Megabits per second how could HD exist without compression.

    720p doesn't use much less bandwidth either, as a complete frame uses about 920,000 Pixels. Remember that a 720 HD stream is progressive so you use just under 1 Million Pixels per frame but every line is scanned each 30th of a second pass. So each second of 720p uses about 27.5 Million Pixels per second.

    John

    From a reply I got in another forum in May 2007.

    "The Blackmagic card is mainly for capturing uncompressed HDMI from an HD camcorder and for feeding a monitor from an uncompressed NLE timeline. It probably won't work as a HTPC capture or monitor solution unless your PC can handle uncompressed HD or SD bitrates (270-1435Mb/s). Be prepared for file sizes at up to 750GB/hr."

    Imagine how big a drive array you'd need to hold 40 hours of Uncompressed HD at those rates. Hmmmm 750Gb time 40 + humongous

    Try doubling some of those numbers. 1080i is about 30 full frames a second. 720p is about 60 full frames a second.

    And don't forget to multiply by the number of bits per pixel for color depth.

    I think a few pixels fell on the floor. You really should clean those up before someone notices that they are gone. :lol:

    and those darn Pixels are all over my floor I had to compress them in my DISH compactor.

    Now back to the subject with Direct Tv weekly release of HD what will dish do to stay ahead??

    Add more HD programming or come up with a new math formula to brag about being #1???

    I'm pretty happy with the current DISH HD lineup - I do get frustrated with having to watch the NFL and Superbowl in standard def. I like HD sports, and DISH did get me Fox Northwest and the Mariners in HD - without even announcing that it was on the schedule - so that was a nice surprise. Then the MLB playoffs come along - and they add TBSHD, pretty responsive. I don't pay attention to whether they're ahead or behind DirecTV - but I'm satisfied with the progress that I see - and what I get compared with 2 years ago. Sure, I'd like to see some more HD movie channels - more is always better, but I've been happy with the rate of addition of HD movie channels. I also like the HDPPV even though I seldom use it -but it's an excellent option if you have guests/visitors and want to find something instantly that you all haven't seen. I enjoy the Monsters HD channel, Filmfest, and RAVE - which I think are all VOOM. I'm just curious to know what is on USAHD that is so appealing? I would check out SCIFI HD, as Sci-Fi/Fantasy is perhaps my favorite genre, but I only like full length movies, not hour long TV series, and my recollection is that the SCI-FI channel movies are filled with commercials? Wouldn't things be stretched etc.? I never watch anything on TNT other than the NBA as I hate all the weird upconversions and weird aspect ratios, and I won't watch ComedyHD or SCIFI HD if they do things like TNT does.

    All they have to do is add the same channels that Direct has and they will have more. Your forget all the voom channels.

    I really don't understand the need to bash channels that a person doesn't watch. Could it be that the bashers don't even have the service bashed? Judging from the posting history of the basher, I would suspect that this is the case. I watch Voom channels as much or more as any of the other HD channels that Dish carries. I would never consider switching services so long as another potential service didn't carry Rave, the best HD channel out there. Would you like to explain your comment, Tony?

    There really is no lossless HD video option either. Lossless is only with audio ...

    USA HD has been showing a marathon of last season's episodes of Law & Order: Criminal Intent, in addition to first-run episodes of the new season. They are doing the same with L&O: SVU. They also had repeat showings of the premiere episodes of Chuck, Journeyman, and Life this past weekend. They are repeating Life after the episodes appear on NBC. They've shown a ton of HD content since DirecTV picked up the HD channel and even the SD content looks great - I haven't seen any of it stretched so far. I've watched some JAG episodes that are in pillar box format and they look incredibly sharp (I'm pretty sure it's upconverted SD, but it looks so good it's hard to be sure). Catherine Bell looks so good on the HD channel I'm thinking of watching all of the episodes again. I'm definitely going to DVR the Boomerang episodes.

    SciFi has a number of their shows in HD now - Flash Gordon and Stargate Atlantis, plus the upcoming season of Battlestar Galactica.
