The wireless speed you are measuring is to the ISP and is constrained by the fibre speed. In reality the maximum throughput within the LAN could be vastly greater even on a 40 MHz wide 5 GHz channel.

Apologies for my dumb suggestions, but if your wifi definitely can't send 4k to your TV, can Handbrake or something similar compress it - would cut the data rate down quite a bit. Obviously this may not appeal with your new top end TV though. For my 1080 files it cut some files by three quarter or more in size and data rate. Its a slow process though.

 

 

 

Also, as a fan, you could try Emby, which is similar to Plex. Install on server / NAS and send media to TV / laptop / iPhone etc. You have to pay for it though (like Plex as far as I am aware).

It beats the heck outta me why you even need 50GB files for 4K TV/Movies you are not going to notice the difference between a 50GB file and say 12~15GB file

If you encode at h.265 then its more work to reassemble on the other end, but less traffic to send the smaller file size via wifi.

Put a false/feature wall behind the TV to hide the cable behind.

Even if you can't somehow stomach this, then an intel NUC mini pic tucked behind the TV should suffice.

Get a new MacBook that supports wireless AC so everything is on wireless AC. Can't see any issues, should do everything

Those files are huge. You should cable it in. Even if you have to get plastic wall cable covers to make it look tidy. I must have mis-understood this last time I read it.

 

A great article on WiFi. Why it kinda sucks and what you can do about it, after reading this 18Mbit doesn't actually seem that bad.

This thread still reads as two issues. One of how to play files remotely, which you should be able to do in a Sony TV, and one of why wifi isn't up to your (admittedly unusual 50MB file size/can't easily cable apartment) requirements, which isn't Sony specific.

Do that TV some justice and get a 4K UHD Disc Player and 4K UHD discs like I do.

We bought a Quad Core 4GB QNAP TS-541A in the weekend plus also 16GB RAM to upgrade it... soon as this is here we will install 4 x 5TB Seagate's into it, update this thread & inform on how we get on.

 

We will run HDMI & CAT6 interconnects from the NAS to the TV, it will certainly mean making (quite) a bit of a mess of the marble & carpet, but, theres no other way it seems to get the files to the panel 'in good shape'.

 

The difference between a 15Gb file, and a 50Gb file, is actually quite noticeable, maybe not on a smaller panel but on a 65' X930D the differences appear marked.

 

Thank you all very much for the assistance, will definitely continue to update this thread in time.

Some points:

 

  • There is no way to reliably play high-bitrate 4K videos on a TV over wireless without transcoding. High-end wireless AC on paper has enough bandwidth, but the wireless adaptors built into TVs are going to be 2:2 stream at best. That means even if you bought a whizzbang spaceship-shaped $600 router with ludicrously high speeds, the TV wouldn't be able to take advantage of them. In my experience high-bitrate 4K pretty consistently stutters over wireless.
  • Your options for getting your 4K files on to your TV are then: either hard wiring (Ethernet or HDMI), or transcoding the files in real time to a bitrate low enough to reliably stream over wifi. The first option has the advantage of the highest video quality and not needing any additional purchases - but involves wires running all over the place, and doesn't help with any other TVs or devices you have in your house. The second option avoids the wires and will scale to any other devices you have, but will involve a drop in video quality - and you need a pretty beefy PC to transcode 4K in real time. A NAS can't do it.

Now that you've bought the NAS, and seeing you seem very keen to watch these huge files at the original quality - I'd say you're on the right track by wiring your setup.

allio, thanks for that, mostly makes sense to us noobies:

 

 

 

It certainly seems impossible to reliable steam high quality 4k media, we tried a top of the line Asus Alien (mostly to reassure ourselves) and it made little to no discernible difference compared to the freebie ISP supplied HG659B… both returned ~100Mbs (99-102Mbs). Wi-Fi & CAT6 with 1-2Mbs in the ‘Speediest.net test’.

 

 

 

You are right, 100Mbps of AC Wi-Fi is not enough, to stream 4k, it stutters… any file >15Mbs will stutter (about a 15Gb+ file).

 

 

 

Q: When people say ‘transcoding’, would this refer to having the source (in this case the QNAP NAS) ‘play’ the files, sending them wirelessly (or on CAT6) to the TV, and at the same time somehow shrinking them? We couldn’t find a NAS that seemed to be ‘rated as capable’ of properly transcoding 4k files… seems that 16Gb Quad Core Intel NAS’s like this QNAP ‘kind of do it’ but are seemingly not good at it (listed as stuttering I think).

 

 

 

Q: We’re running HDMI & CAT6 to the TV from the QNAP TS451A, but we’re not asking this device to actually ‘play’ or ‘transcode’ the files are we? What actually plays the files, assume the TV right? Is having the files on the NAS, and HDMI / CAT6 running to the TV is the same as having a 64Gb Memory Stick plugged into the TV right?

 

 

 

Q: What sort of PC is required to transcode 4k in real time?

 

 

 

Dates for arrival are early May, we’ve ordered 4 x 5TB Seagates so we’ll have to pop those into the QNAP then copy films across, that might take a fair few days, then we can run the HDMI / CAT6 across the room & go from there.

 

 

 

Thanks for the replies, there all helpful peoples.

I can answer all of these together. Transcoding means instead of the original file being transferred in full to your TV, some sort of device instead reads it and recompresses it to a smaller size, then sends the new smaller file in real time to your TV. This gets around the problem of the wireless link being too wimpy to send the original file.

 

I've looked up the NAS you bought and it seems to be quite a fully functioned one, which claims to be capable of transcoding 4K H264 in real time. This gives you three options: 1) use the NAS to transcode your files and then transmit wirelessly to your TV, 2) connect the NAS to your TV with Ethernet and have the TV decode the original full-quality files, or 3) connect the NAS to the TV by HDMI and use it as a media centre. 

 

The problem with the first option is that, as you say, a NAS is pretty low powered compared to a full PC, and its transcoding ability is probably pretty marginal. Additionally 4K H265 (as opposed to H264) is becoming more common, and that definitely won't work - it needs a tonne more horsepower to transcode. I've heard that even a i7 7700K struggles, and you really need a 6 or 8 core CPU to do it. So in that case you would need to add a grunty PC to the chain, i.e. NAS serves files to the grunty PC, which transcodes them using software like Plex or Emby, and then sends them to the TV over wireless. That's hardly ideal, but it's the only way to have reliable wireless playback of ALL high-bitrate 4K video.

 

I suggest you first explore the built-in functionality in the NAS for real-time transcoding and see how well it works over the wireless. If you don't have any H265 files, it might work just perfectly. If you're not happy with the results, I'd connect the NAS to the TV with Ethernet and use the TV to play the original files.

 

If you decide that you're not happy with cables, your only options are to buy a grunty PC to transcode your files in real time, or to manually compress all of your videos to a smaller size.

Or get a 60GHz wireless HDMI link between a separate player and the tv. Have seen some claiming 4k support but not sure if that's proper or just 4.2.2 at 30 hz crap that most things that do 1080p 60 can do.

Xbox One S seems a good buy for this, especially after that recent audio software update.

For the money, the XBox One S is the winner in my books.

 

Add a proper remote and it's better again.

 

The Oppo 203 is losing to the Panasonic UHD player in the best round-up I've seen to date, so that would be my pick for a 2nd place.
