Testers at iLounge say some video delivery applications act differently on an Apple iPad when using the 3G network than they do when the same device is using Wi-Fi access. Specifically, the iPad’s built-in YouTube application strips both standard and HD videos to a dramatically lower resolution over the cellular data connection, something that iTunes Store video previews notably do not do, instead staying at a higher quality and consuming a greater amount of data, iLounge says.
Other third-party applications, such as the ABC Player, refuse to work at all over the cellular connection, producing a notification pop-up that states, “Please connect to a Wi-Fi network to use this application. Cellular networks are not supported at this time.”
But Netflix appears to work fine.
The immediate temptation will be to blame AT&T for the variable performance, but since the applications are executing variably, it seems more likely there are video coding or even playback rights issues at play.
