4K IFE arrives mid-2020 (NH and LH)

Sun Sep 15, 2019 7:03 am

Even in Y... 4K IFE panels. Most interesting is that content storage is at each seat, avoiding backbone congestion.

NH intl F will have 4K on 42" panels!

Does 4K have noticeable difference to 1080p on a 13.3' screen?

That's a hard one.

IMHO it is noticeable if you make an effort, but it doesn't enhance the experience.

Won't notice a difference really, especially considering most content will be upscaled.

Also interested how they talk about being a secondary market because screens that small aren't made for home users. Yet 10.1" and 13.3" are very common tablet and laptop screens. Even talking about how they're so good at spares for older systems which is absolutely untrue.

IME, there is a difference in smaller 4K panels if the panel is OLED and HDR: the higher res and HDR produce better luminance and chroma gradation, even on 13" panels. Without OLED and HDR, I don't see any perceptible difference at 13" and below. Above 14", there is perceptible res improvement... but OLED and HDR are more important than >FHD res below roughly 15.6".

NH will use Panasonic Avionic's IFE. Panasonic's retail panels include OLED HDR models, but the linked article is silent about OLED and HDR. Of course, an HDR panel must have HDR-encoded content to render HDR. The article is also silent about content encoding. That said, I would love to enjoy a 42" OLED HDR panel TPAC... who wouldn't? Oh wait... who's picking the titles? No more cooking shows!

In my opinion yes. It’s just a nicer experience.

title is incorrect..

per article, NH's new 777-300ER retrofitted planes (~Aug 2019) are already flying with 42" 4K in first class and 24" 4K in business

i did sample the 15.6" touchscreen in NH 787-10 PE (which is the same PE seat/screen in NH 777-300ER retrofit). wished more screens were like that (touchscreen is very responsive), though a lot of content was noticeably compressed/pixelated

didnt check if Y had a box under seat

I've only known/heard of semi-centralized IFEs (a box under seat, sharing data for that row). how much of a congestion is there for truly shared IFE?

You see congestion in long load times, and stutters during playback. Higher res, higher data rates per seat ... eliminate congestion with one server per seat.

As for "title is incorrect", you may be better than me in reconciling "ANA will deploy Safran’s 13.3-inch 4K displays to its economy class passengers while first class passengers will use the larger 15.6-inch displays".

with the broken grammar in:

"The airline is rolling out its new Ultra HD experience on 12 re-designed Boeing 777-300ER aircraft used for international flights came into service this past August."

in an article posted on 12 Sept. 2019.

was taking more about the title of this thread... 4K arrived in 2019 since NH has planes flying around with 4K

I saw the article mentioned a lack of true 4K content. Was there any indication within the system if something was being offered at true 4K or simply upscaled?

no, there's no indication (or info) whether true 4K content is available, or at what bitrate/compression


there's a HDMI input for both first and business, so you can still provide your own device and 4K content

Interesting! Wonder how many people would take advantage of this. Would be funny to bring your own Ultra HD Blue Ray player and connect it up.

What about heat dissipation?...those higher-resolution screens need more processing power...

the large 15.6" screen that I used for NH PE wasn't that hot (when I was using the touchscreen). maybe 720p/1080p?

I've felt worse (heat-wise) IFE in economy on older airplanes.

where does the 12 retro-fit 773ER flys to besides the current LHR, FRA, SFO, JFK, LAX, ORD, IAD that I guess , and routes out of tokyo that still supports first class

Only if the data rate is high enough, which would surprise me as you already pretty much can't watch anything on an IFE without compression artifacts now and then..

But in this hypothesis, we assume only the panel size changes, ceteris paribus. Case 1: UHD of Kubrick's 2001 played an Oppo UDP-205 driving current model OLED+HDR panels, I can see differences among panel sizes. Case 2: "2001" streamed from Amazon Prime, I can still see differences. That said, alot depends upon the active path... We know the IFE is not made by Oppo and LG. ;)

Whether or not you can notice the difference depends mostly on viewing distance (more accurately how much of your field of view the screen occupies). You'll notice a difference on a 2" screen if you hold it just in front of your nose. You won't notice the difference on a 100' screen if you are 500' away from it.

Since the article given by the OP mention that the 13" screens will be deployed on economy class seats, how about the distance between an economy class passenger's eyes while seating comfortably and the back of the seat in front of him/her?
