I will guess that as you are replying to this message, you did not receive any reply from someone in the UK with access to Freeview :-) I am myself not in the UK, and so I cannot help you with a stream of one or more Freeview Muxen; also, I do not know the details about Red Button via Freeview there, or such details as `channels 301 and 302' which I must translate in my head into the satellite equivalents which I receive. However, if my experience is enough, Freesat has given me the `quick glance' I needed to see that Red Button exists, and that I can receive it, and, other than that, I'm not impressed -- but it works, and that's the important thing! I should first point you to (if you do not already know) the programs: redbutton-download and redbutton-browser (which I think are on sourceforge). These were written for Freeview (DVB-T) and did not work via sat until the launch of Freesat; then they worked automagically for me :-) > > dish in Zuerich long before I was aware of the spotbeam. > > > i know that i could try freesat albeit has a tight footprint, but i just have > a fixed dish toward 13 east Actually, Freesat itself consists of both services on the tight Astra2D footprint, consisting of the BBC television services, plus the other commercial/PSB broadcasters, as well as services which can be received easily throughout Europe on Eurobird or a different Astra satellite. But the Red Button services are limited, as far as I know, to the BBC UK television and radio services, and perhaps some of the other PSB broadcasters -- most of which are on the UK spotbeam. Of course, this does not help if you only have one dish, but it does give you an alternative if nobody can send you the full transport stream you wish ;-) > > However, the BBC radio services are on a pan-european beam > is there really MHEG over the BBC radio service? Yes, but... I have probably confused you by the difference between the domestic BBC UK services, and those of BBC Worldwide or the World Service... A selection of the BBC UK radio services, just as the television programmes, are broadcast at 28E2. While the latter TV programmes are sent via Astra 2D on a spotbeam tightly focussed on the UK, the radio services (Radio 1, 2, 3, 4 and family, plus 6music and Radio 7) are at 28E at -- if I remember -- 11953MHz, which can be received throughout most of Europe -- that is, if you have a dish you can aim towards 28E... These services, plus Radio London, and several others in different languages, do carry a minimal MHEG service, and I've been able to see that with `redbutton-browser', but it's pretty much the station logo, some information about the present programme, and similar fluff. Which is why I've said, woo, I can see it, now back to work... > do you mean on these BBC "World service" at 13 degree? No, none of the BBC programming directed at the Real World (ooops, guess I can't immigrate into the UK now) carry MHEG info, as far as I know. That means, neither the televisio World Service or BBC Prime (to move to 9E), nor any of the many radio services on Hotbirds, which do not include the domestic services (Radios 1 through 7). So no, you will not see MHEG from the BBC on Hotbirds. Unless I am wrong, but then, I think it would have long since been public... (this is a disclaimer, in case I am wrong :-) First, an apology, in case I am writing at a level which is too simple for you, and also in case I am writing about things which you do not yet understand... Anyway, what I see with `redbutton-download' are directories with the MHEG data, which is transmitted in a cycle, so that you will be receiving identical data after a short time... beer@ralph:/usr/local/src/mini_dab$ ls -alrt /home/beer/carousels/ total 36 drwxr-xr-x 3 beer dialout 4096 Oct 14 04:08 3846 drwxr-xr-x 3 beer dialout 4096 Oct 14 04:08 3847 drwxr-xr-x 3 beer dialout 4096 Oct 14 04:45 3852 drwxr-xr-x 3 beer dialout 4096 Oct 14 05:36 3845 The directory structures under this are too much to show in this mail, but I suspect these refer to four of the BBC radio services on that day when I could not sleep and decided to check out the radio MHEG services. So, what I am trying to say, is that a snapshot of a minute or two will give you the PIDs of the carousels for the MHEG data on one particular multiplex, but it will not give you the complete extent of possibilities for additional services beyond digital teletext, which includes the occasional trigger for ITV-HD or the varied multiscreen offerings on Freesat, which require changing to a different transponder for those services via sat. Also, that you can receive -- with an extra dish -- at least some MHEG data for radio services, which will deliver a constant stream for you to play with, rather than just a minute or three. barry bouwsma -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
