BBC switches to Flash for live streaming

The BBC iPlayer now uses Flash-based streams for live radio as well as on-demand radio on all its UK national radio stations. For live radio, the BBC iPlayer requires Flash Player v9.0.115 or above - which has been freely available since December 2007.

In the UK, the opportunity has been taken to greatly increase the audio quality: doubling the bitrates for most live streams, and using a significantly more efficient audio codec which increases the audio quality yet further. The results are excellent, says the BBC’s Executive Producer A/V Products, James Cridland in the BBC’s Internet blog.

For overseas listeners, the BBC is using 48kbps HE-AAC v2 format stereo streams (known by some as aacPlus) for all stations, excepting BBC Radio 5 Live which is a 32kbps HE-AAC v1 mono stream.
