Saorview audio and visual are out of sync?

    Hi again lads

    Just called around to my mothers house and decided to turn on the tv for a while, when I turned it on picture quality is perfect and so is audio but they are out of sync? When somebody speaks you hear the audio first and then a few seconds after their mouths move?

    The mother says it was working grand last night and there was no lag or sync issues?

    Could this be a transmitter issue rather than a problem with the set up here at home?

    (house near ballybunion co kerry)

    Cheers

    Ah

    Glad im not the only one. Its pretty annoying but hopefully it'll be sorted out by later on this evening.

    I thought it may have been a problem with the STB but probably a transmitter issue seeing as though ye have the same problem.

    Only got my Saorview box a couple of weeks and it has been that way since. It's a bit annoying alrite. Hopefully they'll sort it out. :rolleyes:

    You mean yours has been out of sync since you bought the box two weeks ago? It was working fine down here up until last night :confused:

    Hope it's just RTE doing work on site's although two weeks sounds like a very long time to have that issue.


  • Registered Users, Registered Users 2 Posts: 506 ✭✭✭Alibaba


    Ya. Noticed it shortly after getting the box. Just looking at it now and doesn't seem to be too bad . I'm in Kerry as well so maybe just a problem down here.

    I rang the contact number on the saorview website just there and was talking to someone, they said they were not aware of any issue in this area and nobody had contacted them about it. An engineer is supposed to be calling me back tomorrow so hopefully we can get to the bottom of it.

    I'll keep you posted...

    Not sure if it's a transmitter problem or receiver problem but have you tried uplugging the box for 30-60 secs. Sometimes it can sort out small glitches.


  • Moderators, Science, Health & Environment Moderators Posts: 20,154 Mod ✭✭✭✭Sam Russell


    If you can get mux 2, then the test cards used there are showing video cues for sound sync. Different test cards exhibit it differently. The sound either starts or ends at a visual cue, such as when the vertical bar passes a mark.

    If this is out, it's the box. Otherwise, it them.

    Hi again Cush

    Tried the following but to no avail

    1.Plug box and TV out and plug them in again at the same time
    2.Clear channel list and re scan for channels
    3.Checked for system updates to the box
    4.Unplugged box for 60 seconds
    5.Made sure all leads (scart etc) were inserted properly

    All of the above failed to resolve the problem. Both picture and audio are 100% perfect but the sound comes about 3 seconds before the visual so if someone says "hello" you hear the hello first but 3 seconds later you see their mouth say it.

    According to my mother she was watching the rose of Tralee last night and everything was perfect :confused:

    Could it be a SCART lead issue? Im heading into town this week to buy a decent one because there was a slight buzzing noise since day one and it was suggested this was caused by a poor SCART, maybe this new problem is because of the same lead?

    Hi Sam

    Sorry for being such a noob but I have no idea what "mux2" is or how to test it? Could you explain a little further :o

    Mentioned it back in our previous discussion - http://www.boards.ie/vbulletin/showthread.php?p=73870055#post73870055

    Not on yet, maybe next week. Intermittantly testing with test cards.

    Mux = Multiplex or UHF Frequency channel e.g. UHF Ch 47. All the TV & radio channels, digital text etc. you see on Saorview now are carried in one 8 MHz wide frequency channel or multiplex (Mux 1). A second multiplex (Mux 2) is required by a Ministerial Decision to start by Sept 1st, see the current thread http://www.boards.ie/vbulletin/showthread.php?t=2056216183

    Getting the same up in Galway, since yesterday.....

    Thought it might be my walker box, but I guess I'll wait for more info here.

    Just switch channels once, and back to your programme. Fixed.

    Cush has explained. Currently, RTE NL are broadcasting a second set of test programmes on a second multiplex (mux). Most are test cards. The test cards demenstrate the sound/vision sync using a moving bar. If you can receive these test cards, it will show conclusively whether the sound is in sync or not.

    Same problem with dubbing in Ennis - all day Wed and same this morning. Not a box problem as I have the prob on 2 TVs with IDT. All saorview channels are affected and analogue version of same channels fine. I'm finding it annoying enough that I'm watching snowy analogue rather than the out of sync digital! Sent an email to info@saorview.ie last night, no reply yet


  • Closed Accounts Posts: 11 MiseEireannach


    Just got the reply pasted below from Saorview - hopefully they will be as quick fixing the problem.

    We are experiencing some trouble with the Maghera transmitter which you are receiving your signal from.

    An engineer is on site looking at the matter now and it will be rectified ASAP.

    Apologies again for the disruption


  • Registered Users, Registered Users 2 Posts: 29 wikily


    Yep, appears fixed now.....:P


  • Registered Users, Registered Users 2 Posts: 1,619 ✭✭✭LaVail


    It seems to have fixed itself here too, everything working as before :)

    Hi! I am finding that the subtitles are a good bit of out of sync too.
    Is this related do you think? It isn't just RTE as it is happening on TV3 too :-(
    I'm in Dublin.


  • Registered Users, Registered Users 2 Posts: 11 Greenman555


    This is the response I got from saorview:

    Unfortunately your television is not a SAORVIEW-approved model and is not guaranteed to be compatible with the signal transmitted

    All the best,

    The SAORVIEW team

    I just find it odd that my subtitles are working - but well out of sync. What does anyone else think?

    I must ask them why my Saorview approved Walker also does this on occasion??
    I did mail Walker directly to ask if there there were any firmware updates to improve the crappy response of the telext (tried over the air updates without any result) but it would appear that the Walker technical team operate at even lower speeds than their text does!;)


  • Registered Users, Registered Users 2 Posts: 11 Greenman555


    Yeah - Would be interesting to see what saorview say. I got the impression that I was going to get no joy given that my tv wasn't "approved". Sure email them and see what they say. I got a reply really quickly actually today. :-)


  • Registered Users, Registered Users 2 Posts: 21,499 ✭✭✭✭Alun


    I've noticed some bad lipsync in the last few days here in Bray too, getting my signal from Three Rock. Seems worse on RTE 1 than other channels too.

    Regarding Greenman55's reply from RTE, I'm using Windows 7 MCE .... I guess that isn't "approved" either :) That's just a cop-out reply though, the fact that after the last incident of this, after a few people complained, it magically fixed itself is testament to that.


  • Registered Users, Registered Users 2 Posts: 11 Greenman555


    Yeah - I felt a bit fobbed off... I even highlighted that there were issues before and included a link to this discussion. Anyway - I've noticed the subtitles are really badly out of sync on RTE1 now but ok on RTE2....
    But I'm sure an "approved box" would sort all this out :-) :-)
    Anyone with an approved box have any issue with subtitles?


  • Moderators, Science, Health & Environment Moderators Posts: 20,154 Mod ✭✭✭✭Sam Russell


    You can check lipsync issues by looking at the test cards on Future Services. They all show audio/vision sync with the moving bar and a tone that either starts or stops in a definite place. If it is OK there, then it is probably a transmission/originator fault. The fact that is different on one channel than another is obviously an originator fault.


  • Registered Users, Registered Users 2 Posts: 21,499 ✭✭✭✭Alun


    It seems to have sorted itself out now. Odd.


  • Registered Users, Registered Users 2 Posts: 11 Greenman555


    Yes - mine is working perfectly now (subtitles and dubbing).
    I guess if there's an issue again though someone with an "approved box" is going to have to complain. :-)

    I purchased a set top box yesterday and have noticed a slight sync issue (picture lagging sound by less than a second). Have two TVs already receiving Saorview so checked them and no problems which would suggest the problem is with the STB. However, the STB sync issue is only obvious on RTE 1. All the other channels seem fine, so this has me rather baffled.

    Any thoughts anyone..??


  • Registered Users, Registered Users 2 Posts: 11,907 ✭✭✭✭Kristopherus


    Well, right now, RTE 1 is way out. I'm watching the prog on the President and the sound is a full 2 seconds ahead of the visual.:mad::mad::mad:


  • Registered Users, Registered Users 2 Posts: 11,907 ✭✭✭✭Kristopherus


    Back ok again after the adverts:D.

    I notice RTE1 a good bit out again today. I'm in Dublin West. Not sure who to go as my TV was not "approved", and that is the only thing saorview say when you go to them if you are in my situation.

    Quackster... I'd email saorview if you have the issue again as you have an approved box. There seems to be a lot of this happening. I wonder will it ever get sorted? At least if you email them they'll have to follow up on it.

    I think this is something to do with each programme. Some programmes are perfect and some are well out. Anyone know what could be causing it?


  • Registered Users, Registered Users 2 Posts: 2,647 ✭✭✭channelsurfer2


    rte1 out by at least a second when live programming on such as the news. when you turn on rtenews now its not as bad.. using an lg tv... seems to be the major issue with saorview in most tv's and some decoder boxes from what people are saying.


  • Moderators, Science, Health & Environment Moderators Posts: 20,154 Mod ✭✭✭✭Sam Russell


    I have noticed it particularly on News, but never on the test cards on Mux2. It is a production problem as far as I can tell. I do not watch analogue atall, so does it happen on that? If it does, it is much further down the production system.

    By the way, is the digital (Saorview) the normal service, with the analogue service derived from it, or is the Saorview treated as a seperate production? When 405 was running at the end, it was just produced from the 625 signal just before transmission, so I was curious to know if Saorview would ever be treated by RTE as the premium service before ASO.

    Wouldn't the HD dog show up on RTÉ2 if it was?

    I think it is outside the analogue picture, but the DOG would be added later anyway.

    I've had my Triax 112 Set Top Box since October 2011 and have this sync problem all along. Told by my retailer that I needed a bigger outside UHF ariel. Got said ariel ( circa €43) and problem still persists. I'm in Sligo, about 10 to 15 miles from Truskmore (transmitter), with a clear view of the TV mast. Retailer now says I need a booster for my ariel. Saorview compliant TV's also have this problem.

    Picture and Audio Sync is nothing to do with aerials or reception. Breaking up picture is to do with reception. If your reception (ie not breaking up) you need nothing more than you have already.

    It is caused by RTE's playout/encoder system which I am sure they are well aware of.

    Be aware there are plenty of chancers trying to make hay whilst the sun shines. Bring it back and whack him over the head with it. Anything to make a fast buck.

    Sometimes flicking back and forward between a channel will solve this issue but not always.


  • Registered Users, Registered Users 2 Posts: 7 Jandee


    Modern Digital TVs process audio faster than video and this causes a time lag in milliseconds between the sound being heard and the picture appearing on the screen. Known as lip sync it's liable to appear to be correct and then drift slightly during a programme. It has NOTHING to do with aerials reception or transmission signals.

    Thanks for your reply Jandee and STB

    Might explain why hitting the 'pause' button and pressing it immediately a second time, seems to fix any sync issues I have here.


  • Moderators, Education Moderators, Technology & Internet Moderators, Regional South East Moderators Posts: 24,056 Mod ✭✭✭✭Sully


    Is this still happening to people? All our Irish channels tend to be out of sync, bit hit and miss. Right now RTE1 is out of synch.

    We have a slightly different setup with one box per channel in the attic then fed out to several rooms. Its been like this since we got it a while back and since the frequency changed in the South East yesterday, which was hoped might address it!


  • Registered Users, Registered Users 2 Posts: 7 Jandee


    To save me re-typing I've pasted below my original post from last month -

    "Modern Digital TVs process audio faster than video and this causes a time lag in milliseconds between the sound being heard and the picture appearing on the screen. Known as lip sync it's liable to appear to be correct and then drift slightly during a programme. It has NOTHING to do with aerials reception or transmission signals"

    At present, the Saorview approved boxes don't appear to have a delay option in their set up, to allow lip-sync correction.

    However, if you have a fairly modern hi-fi system, the amplifier should have an SPDIF socket and this can be used to correct the problem. I'll explain about SPDIF in a future post, if necessary.

    My experience of Saorview is with the Triax TR 112 (Saorview only) and the Triax TSC 114 (Saorview & Freeview combination). Both have the same menu set-up and include an SPDIF Delay in the A/V Menu. Check if your set top box has this facility in it's menu, come back to me and I'll see if I can help you.


  • Registered Users, Registered Users 2 Posts: 8 spedygirl


    hi i have bought the 4life combo box and it seems to weaken my sound signal by half on both terrestrial and satellite and the sync is out on satellite only,does anyone have any info on these units-otherwise its great can record and watch different channels ,like record bbc1 watch itv ,ch5,anything so i would like to get sound issue fixed. all help appreciated, thanks carol ;)


  • Registered Users, Registered Users 2 Posts: 7 Jandee


    Hi Carol,
    Please read my post from Thursday last 8.11.12. It'll explain why you have a lip sync problem.

    I spoke with the guy who setup our system and he is of the understanding that its a problem on Mt. Leinster that RTE are aware off and are trying to fix. This is why the audio and visual is not matching up. But Saorview didn't know anything about it.

    All our set top boxes are in the attic, one box per channel fed down to the rooms.
