    I can get watchable analogue VHF from Kippure on an indoor aerial where I am so I tried scanning 198.5 but found nothing. Might need someone with a proper VHF setup to test.

    Maybe they are listening to the voices on here complaing about Mount Leinster jamming the Welsh transmisions. Or maybe they want to jam VHF as well.

    If its the same as on DAB it'll only carry audio rarely - sporting and religious services. Its whats carried on longwave, just with the rest of the time filled with normal R1.

    DAB+ uses the same audio codec HE-AAC as MPEG4 on Freeview HD while the current DAB and Irish DTT use the same ( crap) Mpeg1 audio. If we assume that a lot of our gear will be Irish purpose Freeview HD gear, going forward, then we could have a stab at broadcasting DAB+ which relies on the HE-AAC codec for its plusness. The UK will also deploy DAB+ sometime won't they??

    But I am only specumalating :)

    Irish DTT can use AAC for audio, it's in the NorDig spec.
    MP2 is what DAB and Sky Satellite radio use, difference is that Satellite is usually 256kbps MP2 and UK DAB (MP2) often 128k.

    Since 128k MP3 is unacceptible..

    The issue is not just MP2, MP3 or AAC, but what bitrate is used. There is no quality benefit if AAC is simply used to have twice as many stations in the same bitrate.

    Its been on satellite for EU audiences for a couple of years now. As per above- its mostly R1 highlights, along with some very good plays that normally go out late at night etc.
    Not a bad addition......

    Wonder why? You can get a R1 FM or LW in the clear (from the same satellite) anyhow- so its a bit pointless....... Doubtless part of some bigger plan......

    What audio decoding are they using for the HD test? Can you display the audio information page?

    Brillance, my LG TV is also showing this test card in clear on RTENL2 and it is in HD.
    Will RTE show World Cup football in HD on this channel next month? or run any parallel program with RTE1 SD and RTE HD?

    It would be nice if that was the case, I'd prefer Irish commentary over the commentary offered by BBC or ITV.

    Lets hope the RTENL engineers are thinking along the same lines.

    I have also notice that the AD, Audio Description, feature on my LG on RTENL2 channel is duel audio
    when AD is off, I hear the radio audio
    when AD is on, I just hear the clappers clicking when they meet together.

    Had to retune one of the Samsung's in the house tonight, was giving errors on every channel.

    It and the LG are now giving LCN-ed channels again. My own Samsung isn't! Still alphabetical order on it. Only time it ever gave me LCNs was when the DAB stations were carried for a short while. Anyone any idea why?

    edit: setting country for digital to Ireland gives me LCN, it was unknown. Still no MHEG but I don't actually know if the unit supports that.

    Go to the RTÉ News Now channel and press the text button, what do you get - no text, MHEG-5 text or regular "analogue" text?

    Have noticed previously on a Samsung TV in store that it gave MHEG-5 text on the News channel and regular text on the other channels.

    I have also notice this on all channels except TG4 which never did transmit MHEG-5
    It used to be on RTE1, RTE2, RTENL1, RTENL2 and RTE News. Now nothing...

    Programme listings on MHEG-5 text aren't being updated at the moment. They've been showing listings for Thursday programmes for a few days now.

    That's automation for you! Things break and can go un-noticed for days on end.

    I just noticed this on my htpc RTE 1 , RTE 2 and TG4 have no 7 day epg data coming from the dvb source, however the RTEN_L test channels seem to have EPG up until the 8am on the 29th.

    I've seen it happen before, it was only for a day or two.

    EDIT :- I just forced an EPG update and it all working again.
