We can't deliver over normal broadcast channels because we don't have the bandwidth and there would be very significant costs for a small audience.
We are using MPEG DASH because it handles surround sound well and can be decoded entirely within the browser without any third party software and this will become important as more and more consumer devices such as TVs and set top boxes have web browsers built in. It is also rapidly becoming the standard for audio and visual content delivery over the web and we need to explore how it works. There are more detailed explanations in the blogs from the first experiment using this technology. http://www.bbc.co.uk/blogs/radio3/posts/Radio-3-in-40 http://www.bbc.co.uk/rd/blog/2014/03/media-source-extensions Please ask any further questions via the blog or twitter using #BBCProms4 not through this list, so the questions and answers can reach a wider audience as I don't want to have to answer the same questions twice if possible.

But, after the last test it is obvious that a large majority of us were unable to enjoy these broadcasts due to the limited requirements. May i ask a question as a BBC licence payer. Why is this not available via the standard broadcast methods, Freeview & Freesat?

The stream will be available internationally. So the're available to the world subject to what browser/os you use, but not to me who pays the licence fee. Why must MPEG-DASH be used for this? It's not like it's some UHD Video that may need bitrate considerations. Why not just do a 4ch version of the 320kbit ADTS R3 stream, which works fine with pretty much anything, and also gives users the choice of aac decoders. _______________________________________________ Sursound mailing list Sursound@music.vt.edu https://mail.music.vt.edu/mailman/listinfo/sursound - unsubscribe here, edit account or options, view archives and so on.
