Audio format matching

[John6289]

Apprecite some technical advise as I am confused with the latest dozens of "audio format logos".

1. The main purpose is watch netflix and youtube on my existing samsung ua55mu6300 tv and "to be brought" HTiB, Home theatre in a box set. I believe BTiB is good enough, instead of buying receiver and better speakers. The tv is smart, with ethernet and built in netflix and youtube software

2. Is Netflex 5.1?

3. The Tv setup can select several output modes, dobly digital, dobly digital plus, dts, dts neo 2:5. It has hdmi arc

4. If i buy onkyo ht-7800 or ht-s3800, which support dolby digital and dolby digital plus, would it match with my existing tv?

5. Is it true that as long as tv and receiver have "common dobly digital plus", it is okay and i do not need to use nor worry about other formats, like dts?

6. What is dts neo 2:5? Web search show many dts formats, but not this one

Many thanks in advance

Any TV which properly can receive and output 5.1 surround sound audio that Netflix provides should handle the audio without issue. I have no idea if your TV actually supports this feature, but you should check the TV itself to find out. There is also this information from the Netflix website:

To check if your device supports 5.1 audio, go to any Netflix original to see if there is a 5.1 audio option. If not, your device may not support this feature, or it may need to be turned on.

The digital audio output of the TV can connect to the receiver, or perhaps the ARC can be used to get the audio from the TV to the receiver. It should be noted that the audio will be limited to dolby digital and nothing beyond that as high definition audio is not supported through the connections available. Still, it will sound very good.

If you want better audio then you would need an external player which can provide that audio. At this point, for Atmos support, very few do.

This is how it looks like on my samsung tv setup menu. Only dobly digital and dobly digital plus can be selected. Do not know why the dts and dts neo 5:2 were grey out.

So, if i buy the Onkyo which states that it support dd and dd+, it will work "best" with dd+, right?

I meant, it will not work in "degraded mode", due to lack dts modes.

Netflix show 5.1

Thanks for detailed reply. Really answer most of my queries. Just some clarifications

The samsung smart tv has arc hdmi. It will feed onkyo receiver in dd+ mode, right?

Is dd+ mode better than dts and dts neo 5:2? Hence, i do not need to shop for another brand model that support dts, if dd+ is equal or better than dts and dts neo 5:2. Right?

You'll have to check (in its manual or by trying it out) to make sure your particular model of Samsung TV can forward DD+ (or Atmos) over ARC. Many TVs can't. So far as I know, any receiver which supports Atmos also supports decoding DD+ over ARC.

An annoyance, though, it that CEC (which Samsung calls AnyNet+) and ARC are not always compatible between devices from different manufacturers. They might fail to work at all or they might be intermittent. It's quite frustrating. You'll have to verify that they work reliably for you. Often people have to resort to using an optical audio connection from the TV to the receiver. That can carry DD but not DD+.

Dolby Digital and DD+ are used by streaming services but the various DTS formats are not. The streaming services prefer DD+ because it can do a better job of compressing the audio than DD can, resulting in less data having to be transmitted. Forwarding the various flavors of DTS through a TV usually is necessary only if you have a DVD or Blu-ray player plugged directly into the TV and need to get its sound to the receiver. It's usually better to plug a disc player into the receiver than into the TV, though.

ARC was not designed to handle HD audio codecs. I believe this has been recently upgraded, but I don't know if any TV or AVR has implemented this feature. So, I would not expect DD+ or Atmos to be supported via ARC in any manner.

Dolby digital is about all that can be hoped for, and it's no better over ARC than it is using the digital audio out of the TV directly into the AVR. For what it's worth, I would try both optical and ARC and see if one of them works if the other one does not.

I have seen comments that DD+ can be played via current ARC...no verification myself tho.

This forum and other web info i searched suggest that my tv may or may not be able to support dolby digital plus over hdmi arc and optical output. Seem depends on model and how new version it is.

1. Will dd+ goes from tv to av receiver via wifi or bluetooth? I am choosing these models, some has wifi and bluetooth. denon avr-x1400h, avr-x540bt, avr-x2400h. Onkyo ht-r395 (htin ht-s3800 set),ht-r695 (ht-s7800)

2. If dd+ goes work, will dd likely widely supported by a high percentage of models? Would it be unlikely that they will go to even lower grade format, like pcm, etc? Tv is samsung ua55mu6300, 6 months old, main stream model.

3. What "function" will i loss if dd+ not working, and only dd works?

It can be depending on what plan you are buying. I am on a UHD family plan on #2 son and the TV info last night showed 5.1 on season 2 of Iron Fist.

What’s the goal here? A 5.1 Dolby Digital Plus without meta data (no Netflix titles are 7.1 that I know of at least) or with the Atmos meta data? (Just a few devices support this with Netflix, check link above).

Most ARC has a single mode with only limited bandwidth. There are also some TVs with ARC common mode with more bandwidth. Some new TVs have eARC with even more bandwidth

If the audio system you use is a home theater in a box like you mentioned in the first post the difference between DD and DD+ is unlikly to be noticeable at all.

Not unless it is eARC introduced with for HDMI 2.1.

https://denon-uk.custhelp.com/app/answers/detail/a_id/6333/~/arc-/-earc-compatibility

ARC will full on support all current HD audio formats at some point, but today is not (quite) the day.

That link is actually really solid because it shows that standard HDMI connections with ARC that are currently available support the same audio formats which optical/coaxial digital audio supports. Plus, no questionable ARC issues which pop up from time to time.

Yeah that's the research conclusion I've had but some people insist they've done it and that Denon article isn't listing bandwidth specifics either. DD+ can be dialed down to a fairly low bitrate and I'd assume that's the difference in this? Dunno, but I have seen several postings of people that are certain of it (and their technical acumen seems to back it up, altho just a few instances and I can't find any at the moment).
