Apple TV 4K and HDR

[archer75]

Very likely what you heard is just one of them being louder than the other (which doesn't mean it's better).

Volume appeared similar. But I can verify with a sound meter.
Unfortunately my avr has no way of displaying bitrate that I know of.

Keep in mind that some TV makers implement ARC weirdly. Some only allow 2.0 to go through for some reason. If anything I would test HDMI vs Optical, since they are both known to support DD+/DD (HDMI/Optical).

Mine does DD 5.1 over ARC.

You could use an optical cable instead then. I'm not sure how your TV works, but on my Samsung KS8000 I just connect everything with HDMI to the little box (One connect or something) and then plug the Optical Out into my receiver. I think Optical only supports 5.1 though, so if you have 7.1+ your SOL.

Good, you can answer my question then, I also have the un65ks8000 and just got an ATV4K which I had to connect direcly to the tv because my receiver does not support 4k yet. So how does the audio work out of the tv optical out? is in sync with the picture or is it a little off? Im wondering because going from ATV to TV to receiver, there might be some slow downs...
Thanks!

Ps, one last question, what do you think of the image quality vs 4k blurays? thanks

I’m not sure on the delay, so either I never noticed it or it’s just not there.

I don’t own the ATV4K or a 4K Blu-ray player, so I can’t answer that :/. I would assume a real 4K Blu-ray will look better though. Depends on distance and how much compression the streaming is doing though.

Your receiver is not 4K, but doesn't it have ARC?

I think optical cannot support DD+.

 

[Strelok]

ARC cannot support DD+ either.

Yes it can. And Atmos DD+ (not full Atmos).

If you bought a newer TV or have one that is slightly older and supports it. It looks like the KS8000 doesn't. https://us.community.samsung.com/t5...am-Dolby-Digital-and-saved-options/td-p/55253

The easiest solution is to get a newer AV receiver that supports 4K/HDMI. ARC seems like it's a cluster**** to get working properly since everyone supports it differently.

Ok, what is ARC exactly? I’ve noticed that the ks8000 remote controls the volume on the preamp without me settings any codes. I think is sending a signal through hdmi to turn volume up or down (it knows not to use the tv volume) is this ARC?
I have a Nad Masters Series M15HD2 soon to upgrade the video module to support 4K.

The remote controls the preamp via CEC.

ARC is Audio Return Channel, which allows to send audio from the TV to the receiver via the same cable the latter uses to output the other way.

You might not be able to send 4K video from the receiver to the TV (HDMI 2.0), but it can be OK for 1080p 3D and audio back (HDMI 1.4). But DD+ over ARC is not that common yet.

My receiver does not have ARC (and it cannot pass 3D), so I will be trying if a certain box also converts the ARC into normal HDMI audio (this extractor also supports DD+). I am not sure if my TV can output DD+ via ARC (the format is supported but maybe it is always converted).

Then I could use the ARC input in the TV to output audio to an HDMI input in the receiver, and another HDMI input in the TV to send 1080p video from the HDMI output in the receiver.

The Roku can send DD+ via optical if the stream is low bitrate.

Sort of. Right now this is only available on newerish vizio tv's as they are doing something beyond what is spec'd for ARC. The rest of the tv's, including the high end 2016's LG OLEDs can only do DD over ARC.

There are more TVs that can do it, including some Sony, TCL, and Insignia.

Apple TV will not output DD+ stream from it's HDMI anyway.
DD+ it can decode internally, but from the back it will output a PCM 7.1 audio.
Hence, Atmos is lost in the process.
