[Dtb-talk] iPhone/iPad/iPod touch NLS Playback question

[Flint Million]

I think another possible issue is that the iPod has an AAC/MP3 decoder
in hardware, but not an AMR-WB+ decoder. I may be completely wrong on
that since the iPhone is probably using some kind of AMR audio for the
phone component, but I have never read any specs on it. Also it'd  be
logical that the iPod touch would lack such a decoder even if one is
in the iPhone. (And it could also be that the iPhone's decoder, if
any, is part of the GSM hardware itself and not part of the media
playback chipset.) This would mean we'd be reduced to decoding the
book content in software, which would potentially reduce battery life.
One of the selling points of the iPod touch is its seriously long
playback time - they rate it at about 30 hours for music, which
matches our big tabletop NLS players - but they achieve this by doing
as much as they can in hardware using specialized very-low-power
chips. Anything done in software on the device eats the battery life
away, because the main processor, while efficient, can't compete with
a specialized low-power decoding chip for media content.

And of course, the issue still stands with how to get the book content
on to the device. I may be wrong, but I think Apple disapproves of
methods of loading content that involve simple drag-and-drop. All of
the apps I've seen available on the app store for content consumption
require you to either use WebDAV or FTP or a traditional web server
style upload mechanism. This adds yet another complexity to the
process. Apple's App Store policies seem to include some unwritten
rules about things like this (I'm sure some have heard the stories of
apps being rejected for no apparent reason), so this is just another
thing to worry about.
