Apple Patents: Tailoring Music Playback and Dynamically Prolonging Battery Life on iPods and iPhones

While perhaps not as glamorous as 3D display technology, a couple of other patent applications from Apple reveal that the company is working on improving the audio/video experience of their iPod and iPhones.

Apple describes how they might keep track of individual playback characteristics of songs on an iPod in order to improve the overall user experience. Apple could, for example, track a user's preferences for volume, start time, equalizer settings and other factors and apply those automatically in the future. As an example, Apple gives the start time of a track:

For example, the usage metadata may indicate that a user skips, on average, the first 22 seconds of a particular song so the next time that song is played, the first 22 seconds will automatically be skipped.

In another example, Apple suggests that skipped songs which are rarely listened to might be dimmed out or otherwise obscured in favor of songs that the user prefers.


More frequently played songs appear larger.

Meanwhile, another application suggests that the iPod or iPhone could actively determine if there is enough battery life to play the selected video. If not, the user could be given a warning as well as options to degrade the video settings or reduce backlighting in order to prolong battery life enough to watch the entire selection. When not enough battery life is detected, a warning dialog would pop up giving the user an option to simply proceed or make the desired adjustments:

The System Does not Have Sufficient Power for Playing the Entire Selected Video Segment.

Choose "Adjust Settings" for Lowering Power Consumption or Otherwise Choose "View Video" to View Selected Video for the Remaining Time.

It seems this would be a welcome feature for travelers to avoid missing the last bit of a movie due to a low-running battery.

This sounds awesome. Dynamically changing the list of songs based upon what I listen to and how I listen would make scrolling through my playlists a breeze.

Who votes "negative" on stuff like this?!

This is a good idea. Goodbye, intro to Teenage Riot. No need to fast forward through J vs. S to get the correct playcount on Shady Lane. Et cetera.

That's pretty neat. Like the dimming of rarely listened to songs, and the video adjustment is very cool.

I really wish, in particular, Genius had a thumbs up/down feature like Pandora. I generally think the mixes are quite good, but the major problems are (1) that mixes from the same starting song are almost always the same, in spite of having >6000 songs on my iPhone, and (2) they frequently contain one or two songs that I really don't like (usually freebies I picked up from the iTunes Store), and yet even though I skip them, they keep getting populated into the list.

sounds sort of nice (if implemented properly, software that tries to guess what you want do can be more annoying then useful) but at the same time i really can't understand how this kind of stuff can be patented.

Maybe it's just me, but this is really exciting to me.

Sounds like it could be good.
For songs with long intros or long outros, i just adjust the song length to where it begins/ends via the Cmd-I in iTunes.

I do. Any software that tries to be "helpful" based on past behaviour tends to get it completely wrong and ends up very annoying.

Take the "skip beginning" bit: So I tried to compare the quality of 128 KBit and 192 KBit encoding. Ripped the same song twice, then played both copies repeatedly, always skipping a minute of music to get to a complex part where I hoped to hear a difference. Did that ten times in a row, then deleted the 128 KBit copy. Result: The stupid "clever" software makes it impossible for me to listen to the first minute of the song!

This is the kind of behaviour that Microsoft regularly gets complaints about. Like from a university professor who entered grades into Excel; first three students had an A+, and based on this Excel "helpfully" changed the grades of the next five students from A to A+ because obviously the professor wanted to enter an A+ as before.

In my personal life, Amazon never, ever will forget which three books about a related subject I bought for my daughter as a Christmas present, and it continuously asks me if I want more related books. No, I don't ****ing want _any_ books about this, and three is enough for my daughter, and she has moved on to something else anyway. And the music that I buy from iTunes is very often purchased to fill gaps in my collection, so I might have the best, second best, and third best album of an artist on CD and buy the fourth best on iTunes. So if you judge my music taste by my purchases, you may go very wrong.

And if I play some music twice, its usually because I got a phone call after it started and I missed most of it, so I play it again. So the songs in an album that are played twice are not the ones that are best or that I like best, they are the ones where I got interrupted.

The only good idea is adjusting movie playback to battery life.

This is why Apple software sells the hardware and why other vendors copy it... the enhancement of user experience combined with great hardware... the combination is what makes the differene...
