Re: [Sursound] BBC Proms in 4.0
Firstly, i must say a thank you for letting us know. 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 BBC will make the BBC Proms Concerts available in 4.0 using MPEG-DASH.

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.

Re: [Sursound] BBC Proms in 4.0
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.

I should be interested to know what you mean by limited requirements Did you give feedback at the time of the experimental broadcasts in March? Actually, the glass is at least half full, as far as I am concerned. I am not a lover of MP3 files at all, but I listened in March to nearly all the the BBC R3 webcasts from the Southbank and found the sound quality to be more than adequate. It allowed me to judge the quality and quantity of the surround sound and also to enjoy the music (which is prsumably what it is about). Encouraged by this, I put up on my website some of my own experiments in MP4. This was relatively easy to do and I was surprised by the sound quality when compared with my 24-bit originals.

[Sursound] BBC Proms in 4.0
Hi It looks interesting - but access via the digital networks would be easier. At least it should be simpler than the BBC's Quadraphonic trials back in the 1970's - that required to 2 FM receivers! Not sure that my internet is currently reliable enough - especially in the evenings, but I might give it a try.

I agree dash may well be the future, though from the links in Ruperts other post I see it's not adaptive for this test. My issue is really just the limited browser/OS choice currently, maybe if mine worked I wouldn't care :-) I all for the future - just this content is unique and could be easily made available as a normal stream in addition to the trial. ___ 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.

From one of them People expect to be able to consume BBC content on any platform Yep :-) I do, and this is unique content that I can't consume. There's nothing wrong with trialling this, but given that you know browser support is limited you could have easily provided an additional old style stream. ___ 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.

Stream working well here - shame it's wildly out of sync with the broadcast picture, though. Some distortion apparent on FF passages?

Yes, I heard some distortion on the violins in places: it sounds digital but I wasnt sure where it came from, as I've heard similar from the ORF web relays (stereo). Regarding the lack of browser choice, I agree that it would be nice if all adhered to the HTML5 standard; but they dont. (What's the point of useful standards -- i.e. the HTML5 media tag -- if not everbody uses them?) I installed Chrome for the purpose of listening to these broadcasts, and it has been no trouble. I still use Firefox on principle for other browsing.
