BBC iplayer app bit rates

Assuming you mean "On Demand"    (iPlayer is TV)     .........   its 127kb/s  

...........   full banner reads  HLS 48kHz 127kb/s

Hi there Mike-B,

Sorry mate my mistake I meant the I- radio app. I usually listen to radio via Tune-in when out and about etc. The previous incarnation of the BBC i radio app wasn't all that stable on my iPad for some reason but this new one is much better and sounds very good. On the Tune-in app I get BBC Radio @329kbps so I was just wondering if this BBC app was streaming the same ?

Mike..

OK no probs,  but sorry I can't help much as I have either FM or iRadio at home or FM/DAB in the car,  don't do walking around radio.

Assuming that the app is accessing the HLS  streams from the BBC they would be 320 kb/s AAC.

I believe the BBC use different streams for different devices. So for an iPhone using 3G, you'd get a lower bit rate MP3 stream to ensure better stability. I find playing from the iPlayer radio app on my phone, sending it over Airplay to my Superuniti sounds poor compared to native iRadio on the SU. For listening straight from the iPhone, I suppose it's acceptable.

The BBC seem to be constantly introducing new streaming formats. Last year they introduced the HLS format for some streams, but before it was even launched, they had already announced that they were developing a replacement called MPEG-DASH. 

Thanks Chris. I may be wrong but I got the impression from the long discussions on the BBC blog pages at the time that MPEG-DASH would be running alongside the HLS streams, not replacing them. They were saying that the MP3 streams were only temporary, so I don't know how much longer they will be available.

You may well be right, Nick - given that the Beeb currently seem to have a mishmash of HLS, MP3 and AAC streams. As for 'temporary'- do they mean months, or decades?!

IIRC they were suggesting a year or two for the MP3 feeds. It would be a bad move if they did pull them as it would leave a lot of standalone internet radio devices unable to access BBC radio!

Wouldn't be the first time!

The high def radio streams come in at between 319 and 326 kbps AAC.

The TV programmes, such as the Glastonbury concerts, come in at 93 kbps.
