- [Geeky] O2 re-compressing images on the iPhone
Just did a quick experiment to demonstrate what I was wittering on about the other day.
This is me zoomed in on the image on the STW front page while on WiFi:
And here is the same image zoomed in when on 3G:
Basically O2 are re-compressing images on-the-fly when you're on 3G. Saves them bandwidth and makes it looks like their 3G is running faster than it actually is.Posted 8 years agoskidartistMember
I get the same thing using my vodafone mobile dongle thing on my laptop. Its not specific to iPhones, or to phones, or to 02.
Nothing sneaky about it really, I think its just making mobile internet feasible.
Mind you I'm also sure I've seen the same thing with slow dialup connections. It might be the case that the website you are viewing is serving up images to suit your connection speed and it has nothing to do with the ISP. I generally find that thumbnails will be more compressed, but the images you click through to are notPosted 8 years ago

Nah it's definitely the service provider. Websites don't really have any reliable standard way to know your connection speed.
There are several "Speed Up Your Internets!!"-type services out there that do exactly the same thing.
Makes perfect sense to me, why waste bandwidth on a system not designed for amazing graphic output?
I agree it does make a degree of sense. Though it does suggest that 3G capability is being knowingly oversold. Be interesting to see if there was anything actually noting this in the terms of the contract.
I can see the problem if you're looking for really close-up detail in your porn
How do you think I noticed it? The "stills" on ipg are a blurry mess. Fortunately (and oddly) the err.. "movies" seem fine. 😳
Is your phone still jailbroken with the 3.1 OS update, Graham?
Actually I've just got a 3GS (and given the missus the jailbroken 3G one) so not got round to jailbreaking this one yet, (as I spent most of last weekend restoring a fecked hard drive) but I gather that the dev team has a crack already.
The 3.1 update is a bit flaky though.. My phone keeps randomly turning itself off. 😯Posted 8 years ago
My phone keeps randomly turning itself off.
My 3GS does the same and has done on 3.0, 3.0.1 and 3.1 though it hasn't done it in the last two days (since I did a reboot – hold down the home and lock (top right) buttons until it restarts) and it used to do it about twice a day. I kept meaning to take it to the shop (to see a w@nky concierce/guru – seriously, how lame is that…) but haven't got round to it yet.

What movies are you watching I didn't think it could do movie playback except in mobile formats.Posted 8 years ago
The interesting thing about the internet is that frot almost always leads the charge with technology.
Basically these, err, "sites" all have mobile-specific versions which are set up to output mp4 and other mobile formats directly. Other "non-specialist" sites may not have caught up yet.
And there's always YouTube.Posted 8 years ago
sutrely its a good thing for mobile broadband
Well only if the mobile broadband itself isn't up to scratch and needs a helping hand from sneaky tricks like this.
One could arguably be pissed off that they are paying for "Unlimited Mobile Internet" and the O2 site doesn't appear to mention this little hack.Posted 8 years ago
do you ever stop complaining
Rarely. It's the joy of middle age.
you wanted the compression off, i gave you a workaround that your not using cos it'll slow things down.
I just wanted to expand on a point from a previous thread where I said they were re-compressing images because their networks weren't fast enough to cope.
why do you think they use compression in the first place?
Cos their network is crap.Posted 8 years ago
