Today’s “O’Really moment”
Akamai Technologies is extending its content delivery network to the Apple iPhone as it introduces the Akamai HD Network, a system for streaming high-definition live and on-demand video to a variety of devices. Source.
It’s been said twice in the comments over at Mashable that HD streaming to a device that cannot render HD is a bit of a non starter. It’s not been said with a Douglas Adams line from Dr Who. May as well get started then.
“The concept is simply staggering. Pointless, but staggering”
Actually it’s not that staggering. While there’s a case for streaming HD it’s maybe better if the end device could actually utilize it.The iPhone’s can not and is likely been mentioned just to fulfill the buzzworthy compliant criteria of the release.
The iPhone’s max output currently is 640 x480,the screen resolution of the device itself is is 480 x 320. HD is usually considered to be 720 or above but realistically anything under x2 ( 960) the resolution is really stretching the term and even the mighty 3GS currently falls far short of either mark without an external screen and short of the mark with one.
Thankfully a better post than I can justify the time in writing,without need to claim lack-of-talent, appears over on the streaming media blog. with the main thrust of the argument coming from the Workflowed blog.
Akamai…..as long as it’s above 700 kbps and starts as an HD source, it can be considered HD. So the house of cards of the iPhone claims in the rollout of the Akamai HD Network rests on HD ‘quality’ that’s below that of today’s average standard-definition stream
And in my unrefined language.
Just because you start out with a HD source doesn’t make that which you receive HD. If I were to hold my cell phone to the speaker for you to hear the song would you be happy with the term CD quality being used to describe it? If I have ATT iPhone it’s unlikely the call would last long enough to finish this experiment. That’s the second part. Even running at 640×480 with 2.5Mbps , back to those iPhone specs again, you are still not HD and are still exceeding what you could likely extract from ATT on your iPhone.
In short Penn and Teller don’t need to do a show about this claim because it’s prima fascia Bullshit!
