Bangalore: Certain iPad apps are dramatically scaling back or even blocking the video altogether when on the 3G-ready iPad, according to some new owners. The YouTube app significantly degrades the quality of video, while ABC's TV viewer doesn't allow video at all unless via Wi-Fi. Only a few apps, such as Netflix, appear to work normally.
While at first it was suspected that AT&T had demanded the limits itself, an AT&T representative tonight denied the carrier's involvement. It was suspected that AT&T had demanded the limits, but an AT&T representative has denied the carrier's involvement. Apparently the policies are so far self-imposed. ABC is allegedly prevented from streaming over 3G due to rights issues, while YouTube is most likely emulating the same bitrate scaling seen on the iphone, with the larger screen size magnifying the drops in quality.
AT&T is known to have called for adaptive video quality on iPhone apps to avoid over saturating its network, but it has stopped short of making that a requirement on its own. Self-throttling is common on mobile apps for other platforms, but it has usually been voluntarily imposed to maintain a constant connection rather than for concerns about the carrier or for rights issues.
