It's diagram time. Take it with a pinch of salt but it's a suitable summary...
Code: Select all
vTuner <---> database servers <---> station list maintenance
Frontier Silicon <---> time and location services Other 'portals'
<Your Frontier Account> <----> 'My Added Stations', |
| 'My favourites' |
|-----------------. Numerous audio equipment mnftrs:
V V Onkyo, Pioneer,
Your Roberts Addn. Roberts? Yamaha, Denon, etc.
vTuner is the top level in the chain. They run the database services containing all manner of Internet Radio stations and podcasts. They are in charge of finding new stations and purging defunct ones.
Frontier Silicon bolt on time services (so the radio can get the time and date) and location services. You'll notice that your radio gives "Local United Kingdom" in the menu - this will change accordingly if you go abroad on holiday and take your radio with you like. I can imagine Frontier filter the stations too so that they don't give you streams that are in a format that the radio can't handle.
The term 'portal' is thrown about a lot probably because it's the interface between user devices (our Roberts) and vTuner's database. I'm sure there are a raft of similar portals used by different manufacturers, each with their own flavours no doubt, that connect to vTuner.
An optional step is your personal Frontier account, if you've signed up. This allows you to 'Favourite' existing stations or add URLs for stations that vTuner don't list (if you don't know what this is... Read The Manual!).
Roberts is the last in the chain. Roberts themselves don't actually have any function other than making the shiny box that actually lets you listen to stuff. Of course if that device breaks then it's their problem (and yours!) but if you suddenly can't access a certain station one day it's not going to be because of something that Roberts have done. Yes, Roberts will no doubt be working closely with Frontier and vTuner for development and the like but ultimately they have no real control day-in, day-out of what you can and can't listen to.
This brings me now to the BBC. Where do I begin with this bunch of finger-pointers? Their broadcasting facilities could be burning to the ground around them and they'd still blame your TV or your aerial when you complain that you can't watch the latest episode of Stricly Come Eastenders On Ice. Both Joe and Professor have commented on similar problems with Reciva devices which I don't think is affiliated with vTuner and is a competitor for Frontier, thus indicating something BBC related. All the other podcasts I picked at random on my Roberts worked a charm, it was just the BBC ones that didn't, adding more suspicion.
"Chipset Partners" are manufactures that produced electronic ICs ('chips') with the specific use of connecting to vTuner.
