George Ou over on Zdnet wrote an excellent piece outlining why those too-good-to-be-true HD downloads we see in Xbox 360, and even Apple TV are a bit bogus. He points out that while these services deliver on their 720p resolution promises, the encoded bitrates are so low, compressing the data to such small proportions, that the image within the said resolution has inadequate fidelity. He's dead wrong, forgetting that MPEG-4 generation codecs can take the same bitrates from sources like DVDs and ratchet up the res and quality in the same space. Duh. [zdnet via engadgethd]
