Apple TV, iTunes, streaming regular and hd movies

[Coarse]

I have aplle TV hooked up to my 1080p TV, streaming a hd movie from iTunes. The Internet speed is between 15-20 Mbps. How many megabytes/ gigabytes should be chewed up for a 2 hour movie? How many gigabytes for a regular movie?
Appreciate if someone can tell me how to calculate that in general?

Not sure exactly what you're asking, are you asking what's the minimum speed to stream an HD or SD movie?

At a GB per hour, the speed would be (1000MB / 3600s) x 8 b/B = 2.2 Mbps

HD movies are probably about twice that, and SD may be a little under that.

If the movie is already in iTunes, it's not your internet speed that matters, but your wifi speed (or is that what you meant?).

Just look on your Mac or Windows box - the download size is the streaming size. So 3-10GB for HD movies 1-3 GB for SD.

All I wanted to know is how many gigabytes should a movie chew up from say an 80 gb allowable limit

It varies.

eg1: JAWS [HD] ~2hrs05mins is abt ~4.6gb(1080p) : so 80gb limit would give u about 17movies
eg2: Five Year Engagement[SD] ~2hrs05mins is abt ~1.9gb: so 80gb limit would give u about 42movies

Does that answer ur q?

Ahhh, your internet speed was the red herring, I guess.

Anyway, if you look on iTunes on your desktop (not on the iPad, it seems), it will tell you exactly how many GB a movie is in HD AND SD, so no guessing is required. But, if you don't have a particular movie in mind, the answer was still there: about 1GB/hour for SD, and 2GB/hour HD.

SD movies usually taake 400mb-1.5gb
720P between 1.5-5 gig
and 1080 3.5-10gig

Depend on the movie compression
