After much rumour, the BBC has made its iPlayer TV catch-up service available on iPhone - its first mobile implementation. The service does not use the new SDK nor an iPhone version of Flash but delivers 516Kbps streams in H.264 format through the handset’s web browser, over WiFi - theoretically, this should make it available over iPod touch. It offers on-demand shows transmitted in the last seven days, but only in the UK (BBC Worldwide’s forthcoming Kangaroo project will be international and has pledged a mobile component). Digital media technology head Anthony Rose distinguished between delivering iPlayer to phones with browsers and those without - the former being much easier.
