I have a couple of older TV's that have really slow and crappy interfaces and limited file support.

If i could fix this by a simple card upgrade I would.

And, solves the issues about supporting future file formats, plug in a new card and presto.

robjg63:

Isnt VP8 and VP9 googles codec for high quality compressed video?

HEVC and H.265 (or x265) are a completely different codec.

They are competing codecs. One hasnt replaced the other.

Yup

Edit: fixed my other post

Is this really likely to happen? Would a device manufacturer build a slot in which gets ride of planned obsolescence of their devices and future upgrades.

There are many reasons why it might not happen, including that. However, I guess intel think there is a chance. If I could upgrade the smarts on my 5yr old samsung I'd jump at it.

You can never rely on an appliance for encoding/decoding content for any reasonably long period of time. Often the implementation is severely limited or just plain half arsed. I want my TV to last 10 years, and I'm sure the codecs I'm using will have changed a lot by the end of that time frame.

Just treat it as a dumb 'output' screen, and have other smart devices do all the heavy lifting.

IMHO is more important to be getting the latest (or even n-1 in a bargain) HDMI standard.

Found this page that shows what the 2016 Samsung TV's support http://www.samsung.com/us/support/answer/ANS00050186/ this includes HEVC (H.265 - Main, Main10, Main4:2:2 10)

But then they'll change the slot "To take advantage of new and exciting future products"

x265/HEVC ability was what lead me to the Xbox One S recently, as it can run the VLC app, and the PS4 can't. I can now read directly from a network drive on my computer and play to my TV.

File sizes about about 1/3 of x264 files, so it really is impressive, but requires something grunty to decode.

Like some others have said, I wouldn't be looking for my TV to undertake these duties. For me the TV is still just a display device.

Been testing a 2016 samsung ku7000 4k TV. Its built in player is really good except for audio support. Unable to test dolby atmos passthough as dont have a receiver.

Supported filetypes are here http://www.samsung.com/us/support/answer/ANS00050186/

It supports HVEC Main4:2:2 10 60fps 80Mbps. So far raw 4k UHD bluray rips are playing fine, thats because the titles I have tested are not using the full bitrate the UHD bluray spec which allows 128Mbps. In the future when titles start using higher bitrates there is going to stuttering problems. But that happening not anytime soon.

I found a chromecast ultra via emby cast app to stutter, I suspect roku and many of those streaming boxes would also stutter from trying to play high bitrate 4k UHD blurays rips. Probably because they targeting low bitrate 4k internet streams from netflix and youtube etc.

I could not find any info on what bitrate the chromecast HVEC could handle, But I found encoding the rips down below a average of 50Mbps removed the stutter.

So far a HTPC running kodi would be best for high bitrate 4k bluray HVEC rips.

Some HVEC video to tests your player can found here http://jell.yfish.us/

Does the Xbox One uses a software solution to decode HVEC ? So 4k blu ray rips might have a stutter problem to.

Have you tried using the built in Plex to a Plex server maybe connected through a Ethernet connection to cope with high bitrate.

Considering they sell the xboxes as a 4k bluray player, I would hope that their decoder can take the full bitrate of a 4k bluray otherwise they will have some mighty annoyed people.

Good point. So Xbox One S must be the best 4k UHD player for the price out there then.

Agreed. Though their native media player software (separate to the Bluray player app) may not be able to work with the file type.

Hence the VLC mention, which can.

PS4 can't play 4K Bluray discs from memory.

At this point it can't handle lossless audio formats for surround sound playback (Dolby True HD / Dolby ATMOS / DTS Master HD / DTS:X).

I tried the 140Mbps Jellyfish example on the Xbox One S.

I don't have a 4K TV and VLC player literally just shut the whole system down when I tried to play the file off a USB drive on the rear port.

Tried twice and it switched off both times. Don't have the MS media player app on there, but as I understand it, that won't play HEVC files anyway.
