Streaming ripped 4K films

if the tv is capable of hardware decoding that type of stream, then it will be capable of doing it via HDMI or Ethernet (or wifi, but latter is not wise as it will be too slow for 4k). The same hardware decoder will be used no matter what input.

.

I do not actually see that as a given.

The TVs own internal software will decide how it decodes, from what I have seen many of the "smart" features on TVs are really not up to scratch and are often cross range.

The actual decoding software on the TV has to be configured to use any available hardware and I do not see that as a given.

For example a Netflix app might be able to use HVEC but not a media portal if that media portal is the same one they use on a large range of TVs.

I have no experience of the Samsung's mentioned and that it may not be able to hardware decode a stream is only a quick theory.

Smart features have no relevance at the level we are talking about.

It will be decided at the hardware level how each stream is handled and then handed over to either android or the OS to display once its been decoded, if the hardware cant decode it then fair enough it may then be given over to software (although your initial quote was talking about tv hardware specifically)

The actual decoding software on the TV has to be configured to use any available hardware and I do not see that as a given..

Again you are getting confused as it will be the hardware that handles any stream first, and only much later in the process will any software come into play (whether this is loaded by the manufacturer or user)

While its always possible, majority of the major manufacturers will always try and optimize everything so that the price is (even if its only in their mind) justifiable. If the hardware isnt being used to its best this will make it harder for them to set a reasonable price in comparison to any other manufacturer.

(this is why "market forces" work, and why manufacturers will always make the most of all included hardware as much as possible)

They will not include higher spec hardware etc without writing the bios & OS to make the most of it but the hardware comes 1st and then the software sits "on top".

For example a Netflix app might be able to use HVEC but not a media portal if that media portal is the same one they use on a large range of TVs.

That would only be the case if it was two different 3rd party's doing the apps - in which case it still doesnt stop the hardware being compatible - it actually HAS to be compatible for one app to work

Sony (internally) for example may also have a reason to stop something working on one of their own apps (not being able to play certain types of file) but that just means the user has to use an external box connected to the 4k compatible HDMI connections to get it working and the hardware will still work as it should do at its maximum capability.

I get Domi's point.
Although SMART tv's were not the same Apple hardware based platform , bluecube has, they share similarities; and even if there is hevc hardware decode capability on the Apple/smarttv the different apps may not all use it (or use is as efficiently) so MPC-HC may play without stutter, but vlc may have issues, and similarly on smart tv netflix maybe good but media on a usb stick may stutter (because netflix out of self interest invested in good implementation/programmers)

I am sorry but I absolutely disagree.

To stream a video to a TV you need to run an app on the TV (software , not hardware)this is pretty much regardless of make and model.

All apps are not equal and it absolutely is not a given that any given app can access all functions of the hardware, and they are certainly not all written in house by the manufacturer.

I do understand what you are saying but I absolutely think you are wrong and could give you plenty of examples of other hardware that is capable of doing things that the controlling software can not access.

You can of course disagree, but you would be wrong Im afraid.

I have got a degree in Electronic & Electrical engineering (apart from 25+ years in the industry) so I know what Im talking about.

Actually you dont HAVE to run an app at all and this kind of proves my point.

Imagine for a moment you are just using the tv as a display and nothing else, and using an external player for the source. No apps are being used on the tv what so ever, just selecting for example HDMI1 and nothing else. This will be using the TV hardware on its own (for ease of description Im including the firmware / TV's OS which is constantly running when its powered up) and its only the internal hardware & selected input that is decrypting the stream from the player and placing it on the screen. No software on the TV gets involved at all.

This goes to show that no smart app is actually necessary to display the same quality of image on the screen ( obviously dependant on the player & interconnect also).

This shows the hardware ALWAYS comes 1st, above which is the firmware / OS and then above that is any smart app you care to mention

All apps are not equal and it absolutely is not a given that any given app can access all functions of the hardware, and they are certainly not all written in house by the manufacturer..

I already said the same originally , when comparing optimized apps to standard 3rd party ones. Obviously 3rd party apps are by default not written by the manufacturer.

I do understand what you are saying but I absolutely think you are wrong and could give you plenty of examples of other hardware that is capable of doing things that the controlling software can not access.

List these examples then because market forces wouldnt allow this to happen and manufacturers wouldnt be putting on sale equiipment their own software couldnt make the most of (allowing for firmware issues etc).

Obviously there are systems like set top boxes etc which are sold "bare metal" without an OS and for an instance a KODI supplier picks it up and starts using it for their reference box and therefore its not the OEM (original equipment manufacturer) doing the reselling - in these kinds of instances there will be plenty of examples. We were of course talking about the original manufacturer.

I dont disagree at all, but then again you are talking about 3rd party apps or the OEM ones. Also as you said some programmers take care of the software and how its written and some dont.
I was reading the other day about how a new Sony TV prefers Sony USB sticks and streams perfectly from them, yet other makes (which are reputedly better when it comes to storage) the same files stutter. This could be down to many things, but the hardware itself is capable (in the TV) and its the delivery / software which is having problems. VLC would be a 3rd party app and therefore more likely to not be optimized by the manufacturer.

You understand for someone with a degree in engineering that this paragraph completely disagrees with the rest of your post.
 
I still maintain that 4k rips are pretty much pointless at this time, if 4k blurays ever get cracked (presumably will happen at some point) then the game would change, especially if they can keep the HDR metadata in the rips.

HDR/DV make far more difference to image quality than 4k itself does.

At the moment the best way to enjoy 4k is either via Amazon/Netflix, or via a proper 4k bluray system.
 
@FrankJH interesting

That reminded me of Sony 'mastered in 4K' Blu-rays

Sony 4K algorithms: this final feature is a sweetener focused on giving Sony 4K TV owners a better experience with these discs than any other 4K TV owners. Being part of the same family, Sony Pictures and Sony Bravia have shared proprietary algorithm information to give the best possible upscaling performance on these films. Sony 4K televisions will be able to identify a "mastered in 4K" disc and use an upscaling algorithm based on the same formula used at Sony Pictures to downscale the film from 4K to HD. This secret sauce is likely to give a Sony TV the edge over other TVs that must use less-specific algorithms to upscale the content.

About the point on unsued hardware capability - slightly different - but can have decode chips which have h265 capability but that is not enabled in the firmware. (since that takes up relatively small silicon area, represents an economy of scale to share same chip across product range, or just not to pay 20c h265 license) in a similar manner as original RPI did not have mpeg2 enabled and payed for a license to unlock it


@HungryHippos
yes agree with your point about absence of 4k material for dnla/kodi streaming.
With a sufficiently powerful computer it would be interesting to upscale with best in class algorithms/madVr and stream that, albeit no hdr.
