itunes

It’s Sunday afternoon here in jolly (but exhausted) old England. I just caught a post by George Ou at ZDNET called “Don’t believe the low bit-rate ‘HD’ lie.” It’s right on the money about the reality of downloading HD content as proposed by Apples new iTunes service.

There’s more to HD than spatial resolution. Just as a cheap digital camera might take pictures with a lot of pixels and nonetheless turn out lousy images. Bit rate matters, even given consideration for various compression schemes.
