HDMI ARC vs Digital Optical: Which is Better and Why?

HDMI ARC and Digital Optical are very different as far as what they can support.
Basically here's what each supports!
Digital Optical: 2 channels of uncompressed PCM audio or up to 5.1 channels of compressed audio. End of story. This is the max that digital optical is capable of supporting.
HDMI ARC:
All TVs: 2 channels of uncompressed PCM audio or up to 5.1 channels of compressed audio.
TVs made around or after 2018 may support up to 7.1 channels of compressed audio, including height or upward-firing channels.

In something of a throwback to the old VHS/Betamax battle, the reason that optical connections are called either TOSLINK or SPDIF, despite being the same, is because they stand for 'TOShiba LINK' and 'Sony/Phillips Digital InterFace'.

[@TheOsirisOne]

🤯

[@peter.s.3207]

Further clarification, Toslink is the name of the physical connector standard and optical transmission system, which can transmit multiple audio encoding standard. SPDIF, meanwhile, is the name of the communication protocol used to represent uncompressed, 2 channel audio as 1's and 0's. SPDIF cables can be optical (i.e. Toslink) or standard copper connections (i.e. Coaxial and AES).

I hate that nonsense. CEC is the same way - no consistency between manufacturers in what they call their implementation of CEC. Sometimes whole marketing departments should be made to cage match until they learn to stop that crap. “While other car companies just give you some lame tires, all our vehicles come preinstalled with four high strength power plant energy transfer devices made of rubber and steel!

Great explanation, finally some facts and simple info.

[@gregfaris6959]

Good video! Just a bit of clarification, likely of interest to very few; TOSLINK stands for Toshiba Link, in recognition of the developer of this early optical interface, but it does not describe the interface protocol. That would be SPDIF (Sony Philips Digital Interface), developed at the time of the two industrial giants' collaboration on the development of the Compact Disk, and indeed its data rate and format correspond to those of the CD. You may see the TOSLINK connector labeled "SPDIF", and indeed you may find the SPDIF interface implemented on different connector types (RCA connector). They are identical, but of course you need the corresponding connector at both ends of the connection you are hoping to make, and these days, in consumer devices, the TOSLINK is the most common. By contrast, you will not find TOSLINK connectors on most professional devices, (probably due to tribalism amongst major Japanese manufacturers) and indeed the entire SPDIF standard is obsolescent, but it is worth noting it was never superseded for reasons of higher quality, but lower quality and cost, as well as access to more diverse formats with greater channel counts. Obviously any skepticism you may read into this regarding the success of eArc for high channel counts without compression is purely fortuitous, and not intended by the author.

[@CrashCarson14]

Also it’s important to note with ARC lip sync is usually matched automatically. Though if it is off there usually isn’t a way to change it. With Toslink there isn’t any adjustment and may need to be manually set. Though with Toslink there are some CEC type of commands that can be sent. My old tv would be able to run my sound bar on or off and the TV remote will send a pulse for the volume. Less issues with sync as the TV always just passes the audio, and with ARC it must handshake first before sending audio.

[@JonahMatthes]

Yeah, I've heard of the CEC type commands that can be sent via Digital Optical, but from what I understand, they aren't super common. You're spot on though!

Likely a different type of cable and protocol. It’s not optical cables themselves, it’s the digital optical standard used for home audio equipment

You are not using the consumer TOSLink there. Not that you even could, since these conduct the light through plastic and you would need more than 20 meters of optical cables in a live concert hall.

A 2.0 b HDMI cable 24mbs will happily carry UHD HDR and 96kbs of audio. eARC is required for greater bandwidth which is hardware related, 2.1 HDMI 48mbs is required to take full advantage of that format. ARC effectively bundles two cables into one and using an A/V receiver means only a single cable is required which can be easily hidden or pulled through.

Great explanation! also, as a tip: if your soundbar or home theater is 2.1 (stereo bar and subwoofer speaker), it´s better to output only PCM uncompressed audio via optical, because any other output (i.e. Dolby 5.1 or DTS) will decrease significantly the volume of the audio stream (due to dynamic range and processing). Hence you will have to set the soundbar volume to the MAX and even with that set, the volume will be barely loud. Try it for yourself folks 😉

[@feelda303]

One nitpick: when CD players came out, in the early 1980s, there were no receivers with optical inputs. That only came about with the advent of Dolby Digital in the mid 90s. Before then, if you were going to use the optical output, it was either to connect to the input of a digital recorder, or to an external DAC, typically called a digital decoder back then.

ARC can be a little unreliable on older TV's due to some functions not being implemented or licensed. I found some earlier LG's would constantly drop out the signal with ARC. Also, a lot of TV's don't have ATMOS, even in 2021, so the ARC channel, although supporting it, still may not send the ATMOS channels to the soundbar. This would have to be checked on the TV Specs, not just the soundbar :). The big advantage of HDMI using ARC, for me, is that it can be dual direction Audio if needed. If the Soundbar has multi HDMI inputs, then HDMI using ARC will save you a cable between the TV and Soundbar.

[@paulie0706]

@@veinssublime2164 I think it came down to the model of sound bar and the age of it. I now use ARC to a stereo receiver and the sound never cuts out.

[@benfogarty535]

I tested both connections with the Xbox One X and Optical gave a way louder and clearer signal through my receiver. I was upset that the new console ditched the optical port

Fantastic video. Thanks for making it short, sweet, and to the point. Def getting a subscribe

Thats what i was looking for last 2 days.. Thanks for such a useful information.

What I really like about HDMI ARC, is that I can controll my entire setup (tv, soundbar and Shield TV) with one single remote. When I turn on my Shield TV, both my soundbar and tv starts up as well. Same when I want to turn them off.

[@nazeershaw66]

Have to try it. Thanks 👍

[@EazyDuz18]

I can do that without ARC tho. My Xbox has settings so that I can control the 5.1 connected to it via optical audio and my tv all link up so tv controller controls surround sound audio

[@TheRealLaughingGravy]

One thing you didn't mention - at least on my TV, which is nine or ten years old - is that the digital optical volume control is separate from the TV volume control. In fact, there is NO volume control for my digital optical audio. Turning the TV's speaker volume up or down has no effect on the volume of the digital optical audio. My TV's only audio output (other than an HDMI ARC port) is the digital optical port, so I have my headphones connected to the digital optical port through an analog converter. My headphones have their own volume control. When I watch TV late at night, I mute the TV speakers and listen through my headphones, adjusting the headphones' volume control as needed.

Very good info, clear explanation, nice graphics. Thank you!

[@naz0079]

Brilliant and clear explanation. Thumbs up mate!

[@kmac540]

Great breakdown - as someone who deals with this day in and day out I only have a minor correction / comment. Toslink absolutely supports 7.1 (DD+ / Atmos) just not in lossless compressed format. Anytime you see DD+ it implies Atmos too - you certainly get more headroom and better (if not very noticeable) clarity / channel separation.

[@dannyboy8474]

Use the movie prometheus when they are returning to the ship and the sand storm hits them. The difference on ARC with 7.1+ is insane. It makes me sad that windows doesn't care about audio.

[@mindrover777]

It does. Good to know. Does toslink support Atmos on soundbar too?

[@ckought69]

They really need to come out with a new optical standard that can put through newer things like Atmos and TrueHD. It shouldn't be that difficult, considering how much optical data transmission rates have increased in the past 35 years. It could even be backward compatible by using different light wavelengths for different standards (red for PCM / DD5.1 & blue for Atmos / TrueHD).

Not difficult, you must listen. Doing Bose 900 sound bar ant 700 subwoofer. He PLAINLY stated use HDMI eArc for best sound quality.

[@davecarsley8773]

@@scottsmith7756 Not difficult. You must read. He clearly stated in his comment that he's talking about OPTICAL. That has nothing to do with HDMI or ARC. Don't be such a dick-- especially if you're not capable of actually reading or understanding the thing you're replying to.

I agree with you. However, it will be hard to find a company to upgrade optical devices. Especially, when HDMI already taken the market.

Really good clear info, thanks. Getting my Klipsch cinema 400 tomorrow and this helped a lot. Kudos

[@MkProductionQ8]

its all about limitations . HDMI Can Support a wide range of Audio Codecs like Dolby Atmos and DTS-X , the Digital Optical Can't support atmos etc, it only supports Dolby Digital and DTS 5.1 old codecs ..

[@David35687]

I’ve got a basic 5.1 audio amplifier connected via HDMI and optical to a Blu-ray player. I use the Amp to send a 1080P HDMI video signal to my 1080P TV. My older TV does not have ARC. With some of my Blu-ray discs with sound formats like HD-DTS, I don’t get the center channel while watching. However, when I send the audio input through the optical cable, I get the center channel. I think the optical cable out of the Blu-ray player seems to translate the newer multi channel format into the 5.1 format that my Amp wants to use. I don’t mind having multiple remotes and I’m afraid to upgrade anything on my system that’s going to end up obsoleting my older components. I am gonna go without upward firing speaker channels and a universal remote, no thanks.

[@paul8926]

You would be very surprised to know how many people don’t know the difference between HDMI ARC and Digital Optical. I always have to school my family and friends on how to connect their gear properly.
