لان القنوات الاتش دى كلها 1080 i و القنوات العادية 576
اما سؤالك بالنسبة ل 1080P دى حاجة شبة مستحيلة مفيش اى قناة بالخاصية دى نظرا لانها تحتاج من اى قناة تكاليف عاليه جدا حتى يتم تطبيق تلك الخاصية

************************
At present, 720p and 1080i cameras output video at about 1.5 Gigabits per second, but 1080p would roughly double that to 3 Gbps, Pagano says. To convert that into a standard 19.4 Megabit per second channel for transmission across a cable network, "there's a whole set of other technologies that have got to be accomplished in between there."

While video channel bandwidth does depend on the compression scheme used, 1080p would likely require greater compression or greater bandwidth. That's one reason Starz! Encore Group isn't actively looking at the 1080p format, according to John Beyler, executive vice president of technology operations at Starz!.

"It would take too much bandwidth to do it. 1080i barely fits for some types of content–for example, sports–and concerts and specials," Beyler says. "For some types of content there just are not enough bits with 1080i. 1080p would be even that much more demanding."
