Hi Ehlerz

I don't think it's because of the distance (unless you have a villa with more than 50m distance).

By how much should then the Video (and audio) be delayed in your opinion (BTW, it takes a lot of memory and processor to delay a full hd picture)?

You mean it should delay the same as it does for the audio on ML. But then as I described above, the delayed video and audio arrives at the link-TV at the same time when it is played in the mainroom. Now when you have a BV7-40 as a link-TV, this 7-40 has to delay the sound while creating the picture. Then 200ms later the 7-40 link-TV would play the sound and the picture. But this is 200ms later than in the mainroom (and in fact 400ms later than from the wall).

It seems, that all your other TV's either have that very fast picture processor to not having to delay the sound or their picture is not in full sync with the sound.

The sound delay is needed to give the picture processor time to create the picture.

I fully understand what you would like to have, but I think that there is no solution to fit all the different needs.

Hi again, i am not talking about delaying a HD picture, but the equivalent downscaled to SD as the tv already does. Be aware that I am only talking about the old ML system and coaxial distribution, not the future CAT7 solution. SO here is an example. In my case, the linkroom tv´s has no independent delay, because they cant receive digital signals out of the box, and hence does not have to process anything. SO here, the RF output from my mainroom should be the same as the audiodelay to mainroom speakers. IN your case, or the case you describe, be aware that when you use a newer 10-40 as linkroom tv, you will set this up with the delay that suits your DIGITAL DVB-HD input that needs processing just like your mainroom tv. BUT when you watch say a DVD source from your mainroom, this signal is not digital anymore, but downscaled, hence your linkroom tv will NOT need to process it, AND not need to delay the sound. I don't know if the delay settings on the tv´s only apply when the signal is digital, otherwise when you receive the synched SD signal from your mastertv, your linkroom tv will delay the sound, and then make sound and picture unsynced. but if it only applies to digital signals, you will not have a problem on your 10-40 either. IF it delays everything, regardless of digital or analogue, it should be possible to set two different delays, one for analogue (0 ms) and one for digital. SO yes there might be some work in making it work, but i really do not think or hope it is impossible. Has anyone else god an opinion on this, i mean it will definitely be solved when CAT7 is introduced, but what about us with older Linkroom tvs? It would be wise to introduce RF out delay for older linkroom tv´s, while owners of newer tv´s will rely on the CAT 7 distributing everything digitally and process the signals in every room independently.

 

What do you guys think, am i totally wrong in pointing this issue out?

 

P.s: Maybe we should start another thread about this issue as i am sure a lot of others could benefit from this as well :-)

All signals are processed, not just digital ones.

Any LCD/Plasma TV has a 'digital' display.  Some have a variety of picture processing (such as the pixelworks chip in the BS3) that clean up or enhance the picture.  Everything and anything's going to go through this - analogue will need to be sampled digitally, and digital just fed straight in.  These take time, hence the sound delay.

It's not really possible to know what delay the TV accepting the RF input is going to suffer.

To be honest, I solved this by turning the delay to 0 on my BV7.  I must be totally blind or oblivious, but I can't even see the sync difference.

Hi csmager

Ok, admittedly it might not be as easy as first anticipated :-). However, can you guys live with this??? i absolutely can not in the long run.

Wow, sounds great that your delaysettings are so minimal, unfortunately  it varies from provider to provider and I have to set my audiodelay to 250 ms for the sound and picture to be in synch. That, unfortunately is very noticeable in my linkrooms :-(

But i am happy for you, you dont even need the 8.12a update then :-)

Hi Ehlerz

What happens if you let the sound in the linkroom run thru the ML when watching DVD? That is selecting AV+DVD to get the sound over ML, then the sound is also in stereo.
Do you still have sync of sound? But no sync between picture and sound?

 

Hi Beolion

But will this not just give me the sound and NO picture? IF it does, the sound is in synch with mainroom, but i cant get a picture at the same time, can i?

You'll have to use LINK+<Video source> to get picture via the RF and sound via the ML.

Hi

All I do in my linkroom if I want to watch DVD is to press DVD and then I get the sound and picture via the RF. If I then afterwards press AV+DVD on my Beo4, then the sound comes from ML, and the picture still comes from RF.
But I wonder if the sound and picture will be in sync with the SW 8.12 then.

Hi Beolion

I think the sound and picture will no more be in synch if you do that. But again, why would anyone want picture from RF and sound from ML  at the same time, when the synched sound is also distributed via RF?

I will have to test that later today, but i am convinced that EVERYTHING over ML is delayed. So IMO, B&O has solved the synch issue in audio linkrooms, but not video linkrooms...

Rf = Mono. ML = balanced stereo. One very good reason!

I have now also sw 8.12 on my BV9....thanx GBG....the curtain was fast before, but now!!...it´s very slow!!!

ok it´s little better then before....nice that you can rename source....but when I press on my BV9(let´s say DTV) that I rename to "canadigital" it shows that first but then before picture comes it display DTV also...[:'(]

these danish guys......

what hardware do you need for HD in linkroom?except running CAT7 cable??

Can anyone please help? I have a 7-40 MkII, type 9354.  Apparently the software level is 7.0.   

Is this the latest software update for this type, or are there later ones?  If so,  would you please advise the subsequent updates for this model. 

 Very many thaks,
