I used to be down on streaming and lossy codecs. Not any more! As usual the classical arena leads the development, not the world of pop.
The big advantages are codecs that do better with less. I never liked mp3 and its past its sell by date.
I like AAC plus the best, especially if coupled with MPEG Dash.
In my view AAC and AAC plus are better than MP3.
The BBC now use AAC plus coupled with MPEG DASH, the latter being codec agnostic. DASH is an adaptive streaming system. It times with bursts, often 20 sec or more apart. It knows your buffer capacity and when it has a clear shot to your rig. It pretty much stops stream interruptions.
The other advance is native decoding in Windows 10 which does not need flash player. It decodes Dolby Digital plus which my pre/pro can not, so I now have Netflix in 5.1.
When I get BBC UK radio or TV the audio is AAC plus with MPEG DASH. This is equivalent to 320 kbs, but remember the streaming is dynamic. The Proms I down loaded and could watch for 30 days, had superb HD video and audio download the bit rate was 640.
Of course it does not end there. The BBC microphone system and mix is absolutely wonderful and this year was astonishing for realism and dynamic range. I have to say I think most of these broadcasts were the best audio I have ever heard.
For US audio only iPlayer the bit rate is equivalent to 96 kbs. The Stream out of Salford UK though is definitely better and is true HD audio.
The Berlin Philharmonic Digital Concert Hall and Medici TV have also improved apace.
AAC plus 320 kbs at least MPEG DASH. I can tell it is MPEG DASH.
MPR have gone to AAC plus. Live stream seems to be 96 to 120 kbs, and the archived 320 kbs. They are not using MPEG DASH.
Some of the Medici TV broadcasts have been superb, especially a concert including the Saint Saens organ symphony.
The BPO is uniformly excellent. However for shear impact to deliver the full impact, with beautiful string sound, brass, woodwind, totally realistic percussion and organs that shake the floor, the BBC are now in the lead. In fact when it comes to strings I have never heard them more realistically captured that at this year's Proms. It was a wonderful season, and quite frankly I think as good or better than being there.
The BBC have just announced that they will start a subscription iPlayer service in the US in 2016. The starting date is not even hinted at yet, nor what will be on offer. Some or all programs will be on offer for purchase as a permanent download, not one that vaporizes in 30 days.
Every day that passes I rejoice I do not have to deal with the pop culture with its offerings and very second rate (probably third or fourth rate at best) engineering and technology. If that is all you listen to then probably a very basic system is all you need.
