The iPhone and iPod touch are able to stream shows using iPlayer over WiFi. Currently the iPhone is not capable of streaming video over cellular. The video is 400Kb/s H.264, while audio runs as a 116Kb/s AAC stream.
Anthony Rose, writing on the BBC internet blog, said: "We started with iPhone because it is the device most optimised for high quality video currently available."
"It displays the BBCiPlayer site and BBC programmes nicely."
