DAB sounds worse than FM, Internet radio & radio via digital TV
FM stations WILL NOT be switched off in 2015 - that date has been dishonestly set early to scare people into buying DAB now. FM stations won't be switched off until around 2020

BBC has begun testing higher bit rates for the live Internet streams


15th November 2008

The BBC has finally begun testing higher bit rates for the live Internet streams, as they've launched 96 kbps WMA test streams for all BBC stations apart from Radio 5 Sports Extra and the World Service (the World Service isn't changing yet). The BBC is planning on using the WMA format for both the live and on-demand streams that are delivered to Wi-Fi Internet radios, because Wi-Fi radios don't support the Flash format, which the BBC is already using for the on-demand streams available via the BBC iPlayer website, and it's going to start using Flash for the live streams as well over the next few weeks, when they begin using AAC+.

The following table shows the URLs for the 96 kbps WMA test streams. Clicking on the links should launch whichever media player you use that plays WMA files. To manually play the streams, copy the URL, open your media player, click File > Open URL or File > Open, paste the URL in and press enter.

BBC live Internet radio streams update

There have been some other developments for the BBC live Internet radio streams lately as well:

  • The test streams above are being delivered using the BBC's new 'Coyopa' servers, which means that the audio isn't being 'transcoded' -- transcoding means that the audio is decoded from one compressed format followed by being encoding to a different compressed format, which degrades the audio quality.
  • AAC/AAC+ versions of the live streams are going to be launched alongside AAC/AAC+ versions of the on-demand streams over the next few weeks, and these new streams will be rolled out on a station-by-station basis with both live and on-demand streams being launched at the same time for each station.

A note about the Flash format

Just to clear up any confusion over the fact that the Internet streams are both going to start using the Flash format and they're going to start using AAC+ shortly as well: Flash is a "container format", which means that it's a format that contains other media types -- or in streaming terms, it carries other media formats. For example, the on-demand radio streams available on the iPlayer website are already using the Flash format, and the Flash stream carries the audio, which is using the MP3 format. And when the BBC switches to using AAC+ for the live and the on-demand streams over the next few weeks, the Flash streams will just contain AAC+ audio streams instead.

Playing streams with WiFi radio

By Bruce

When I added the Radio 3 stream to my stations for my Roberts WM202 account at frontier radio it plays OK but the display [and the entry on my account] shows it as a 32 kbps MP3 stream. Any thoughts?

I've just tried adding the URL above for R3 on the www.wifiradio-frontier.com website and listened to it on a Roberts WM202 I've got here, and judging by the sound quality it is the 128 kbps WMA stream - the quality of 32 kbps MP3 would be far lower.

So it'll just be a bug with the info the radio is displaying - I'll report it to someone at Frontier-Silicon, so hopefully it'll be fixed in a future version of firmware.

Jake,

The reason why the URLs in the table on this page were originally of the form (I've changed them to the proper bbc.co.uk URLs now):

http://www.digitalradiotech.co.uk/internet_radio/bbc_test_streams/Radio1_96_kbps_WMA.asx

rather than them being URLs for bbc.co.uk was because when I wrote this article the live streams were only testing, and if I'd have given the official bbc.co.uk 'playlist' URLs, such as:

http://www.bbc.co.uk/radio1/wm_asx/aod/radio1.asx

then anybody clicking on those URLs would have ended up listening to the old lower bit rate streams (because the higher bit rate streams were at the bottom of the playlist, and people receive things at the top of the playlist first), which would have defeated teh whole object of this article being about the new higher bit rate streams.

BTW, playlist files are files with an extension of .asx, .pls and .m3u, and they're just text files (albeit the text is structured according to a specification) that contain the URLs of the streams themselves. For example, if you right click on:

http://www.bbc.co.uk/radio1/wm_asx/aod/radio1.asx

save the file and open it in a text editor such as Notepad for Windows, you can see the list of stream URLs.

Until recently I was able to use the radio 6 and 7 streams from USA. Is there any non-real player (iphone compatible way) to listen to these now?

By Denis

Here in Australia unable to get any BBC Radio stations on the snazzy PURE Evoke Flow. PURE are unsure why. Can get every other radio station under the sun it seems . Can listen to all BBC stations via iplayer or Real layer on computer.

Any ideas appreciated.
 
 

Real on Iphone

If you want the Real streams on an iPhone or iPod Touch, there's a player that will work with Real available in the Apps store - WunderRadio. It's not free, but it does work. It deals with other media formats as well, of course.
