Apple trailers: when 720p isn’t always 720p

One of the best places to look for high-quality movie trailers is Apple Trailers. They have lots of bandwidth and a large selection (altough they don’t have e.g. the new Indiana Jones 4 trailers, which are exclusively on Yahoo HD trailers).

Apple typically offers its HD trailers in 3 formats: 480p, 720p and 1080p. The “p” stands for “progressive” i.e. not interlaced, every frame is a full picture instead of only the odd or even lines. The 480 in “480p” stands for the number of lines in the image. 480p is roughly equivalent with DVD quality, 720p is “HD Ready” and 1080p is “Full HD”.

But let me give a concrete example of the resolution of 3 trailers:

Buying an HD-Ready TV

I get the question a lot, so I thought I might write a post about it as a ready-made answer to the next few.

“I’m gonna buy a new (LCD) TV, should I go for HD Ready or for Full HD?”

Nothing even remotely like HD

1. What’s the difference?

Full HD is (at least) a 1920 x 1080 pixels (also called 1080i or 1080p, depending on whether the signal is interlaced/not as good or progressive/better) resolution. An HD Ready TV will typically only have a 1366 x 768 (WXGA) resolution, but it will still accept 1920×1080 input (that’s why it is ‘ready’).

2. What’s your budget?

You will have a hard time finding a TV that is “Full HD” under the 1000€ mark (Pixmania now has 1 Hitachi of 975€). If you want to spend more like 600€, that solves a lot of difficult choices!
