    AppleTV X - I am playing with something new

    Interesting. Sounds promissing :) I have issues when I pick non-HDR material tho. As long as the Envy gets out of the way and the ATV does not flag the SDR material as HDR then that should be ok. I use Pluto TV and the Classic TV section to evaul who well a processor is working along with high...

    Exactly... And when you go to settings, turn off System > Updates > Auto updates.

    AppleTV X - I am playing with something new

    Sadly, I can't fix Apple induced issues. I recommend turning off auto updates. Dont fix what is not broken. Overall in everything I do from IT, to automation like Crestron to computers and even cars,,, DONT UPDATE UNLESS THE UPDATE ADDRESSES SOMETHING THAT AFFECTS YOU or if there is a new...

    The plasma project

    Wellll.... I was bored and I have a Panasonic ST60 plasma that sits next to my Sony A90K in my lab... I use the Panasonic as part of pic quality evaul because it has nearly no video processing. Over a long time tho, i have clearly seen that from a suitable distance, the Plasma can hold its...

    AppleTV X - I am playing with something new

    This will be a fun project. Modding a Sony OLED should be really fun. It will be VERY interesting to see what performance improvements I can get out of it. I want to have the best display known in order to REALLY see the Apple TV X. I was talking to a friend who is a SMPTE, SPIE, AES guy with...

    Oh really.... Hmmm.... I liked the LG panels in Sony... I wonder what my 42" A90K uses..

    AppleTV X - I am playing with something new

    Mad Scientist, hahaha.. Well... It so happens I just bought a Sony 42" A9K. My intent is to mod the **** out of it. The smaller size is because the smaller size panel requires less power, less power means the regulation of the power supplies can be better and have less noise. Well, once I am...

    AppleTV X - I am playing with something new

    I have to give a shout out to Alex. He was asked by one of his clients if there was anything that could be done to help a AppleTV. We had talked a few days earlier and so Alex gave him my info and that resulted in my first real sale of a ATVX. So thank you Alex. I had a LOT of beta testers that...

    Audio extraction. A number of people i know are using this for 2ch extraction into high end DACs. https://keydigital.org/category/4k-18g-hdmi-switchers-with-optical/KD-Pro4x1X-2 This has come up and looks really nice. I do not have any direct experence with this tho...

    AppleTV X - I am playing with something new

    I think ATVX owners are seeing, and hearing, more then even post and DP people are seeing, so its no surprize we are uncovering all sorts of stuff that post and DPs most likely could not see. I have recently become really aware of depth of field focus on STart Trek The Orginal Series. Its quite...

    WHATS UP ALEX !!!!!!!!! It has been a bit, We should talk on the phone :) Its always fun to talk :) Sorry I somehow missed your post :( Thank you, its been a fun adventure. I have learned a LOT of interesting things, some of which seem to be unique. I say unique because i have passed some of...

    AppleTV X - I am playing with something new

    The bitrate for HDR is the same as SDR. A HDR stream is just the SDR stream plus HDR metadata which is very very little bitrate. The whole point of HDR is to use about the same bitrate as SDR and hence why they do perceptual based lossy compression. The other advantage is its one stream for SDR...

    AppleTV X - I am playing with something new

    So a lumagen, and maybe the MadVR, is way better at tone mapping then most displays. So if your going to do HDR then a processor is most likely better then a built-in tone maps on a display. A video processor might also better at gamma and color space then a display is. So there ARE...

    AppleTV X - I am playing with something new

    Oooo.. Good question... I have not personally played with the MadVR.. I know some clients have one, but I have not heard anything from them. So I do not know. Jim at Lumagen tho is REALLY smart. Its a good product. I would need to do a direct AB with C being no processing. I would start with...

    AppleTV X - I am playing with something new

    Well there is no such thing as a HDR display. Science cant do that yet. The real spec is a MEASURED 1,000,000:1 CR. If a device uses tone maps, its not HDR. A tone map is used to fit a HDR pic into a SDR space. Projectors are the lowest CR. Remember HDR is a perceptually lossy compression. The...

    AppleTV X - I am playing with something new

    Yes, A very good question... Experimentation is required to get the best audio & video in each system.. Ideally... In a surround system.. I use a Datasat rs20i to switch audio/video and this output goes to the projector. I dont use a Lumagen even tho I have one. For me the Lumagen was used to...

    AppleTV X - I am playing with something new

    Well yep, it will trigger HDR and show HDR flags and will look like its HDR, but,, if you look at the HDR metadata,,, there isn't any. So no remapping occurs. HDR works by remapping the native SDR stream pixel brightness frame by frame into a new brightness in the HDR space. Then a tone map...

    AppleTV X - I am playing with something new

    One thing to keep in mind. I have a VPLGTZ380 handy and my Sony OLED A90J just blows away the projector for picture quality. The OLED shows so much more contrast ratio its insane and this makes it look so much clearer. Projectors have loss that is unavoidable because of the light path and...

    AppleTV X - I am playing with something new

    I have also seen some weird stuff. Like HDR gets turned on, and the show is "in HDR" yet there is no HDR metadata. So it just shows the native SDR stream.

    AppleTV X - I am playing with something new

    Interesting.. I think we have a very clear view of these streams. HDR is just metadata, not more bit depth or detail. These poor cinematographers and DPs. WHo knows how the whole SDR/HDR thing is going on thier end. What displays are they using, what tone maps,, and then what happens in post...

    AppleTV X - I am playing with something new

    Interesting. I was just discussing this over at the Stereonet forum. I think it is VERY system dependent for a huge number of reasons. I have a Wireworld platinum 48 and a WIreworld Plat 7. Its weird to go between them. The 48 has more detail, but, looks a tad artificial VS the Plat 7.. BUT...

    AppleTV X - I am playing with something new

    A LOT of people have asked me which HDMI cable is best.. This is a hard question. Its really system dependent and the differences can be quite personal. Its tradeoffs. More detail, but kinda artificial. Differences in the Pantone like color accuracy. The 3D feel.. Sound wise its just like...

    AppleTV X - I am playing with something new

    I have looked at the key digital. It would be hard to mod that. This device looks pretty awesome tho. I have not looked inside that one yet. https://www.jvbdigital.com/vanitypro.html?id=255624296&quantity=

    AppleTV X - I am playing with something new

    I do 2ch mostly. I have not noticed any lipsync issue myself. I have a bunch of clients using it in high end 2ch rigs and they have not mentioned any issue. Doesn't the surround processor processing introduce more processing delay ? Picking it off directly without processing would seem to not...

    A fun vid... Making a ATVX.. The fast version.. This does not show the main board rework, that is done by a SMD rework company. It also does not show me potting the cap area.

    That works great tho. Take care in the digital audio cables as you would a high end digital audio source.

    AppleTV X - I am playing with something new

    There is no way to do this. That signal does not exist on the board. You cant add a chip for it with out doing something in firmware and I can't/wouldn't do that. It sure would be awesome. But a external HDMI device like the Key Digital or a Oppo is the best way. Unless someone could somehow...

    AppleTV X - I am playing with something new

    Yes.. What you said... BUT.. Its SURPRIZING how well the clarity and stuff gets thru. The source HDMI device has a lot of affect on devices downstream. There are a number of clients using various ways to pick off audio. Here in my lab area I have a Oppo that is highly modded and it has a HDMI...

    AppleTV X - I am playing with something new

    DIY is fun ! It still gets you a big jump. Of course its quite the project and its a tiny space. Its worth it tho. WELL.. Pic/sound seem the same. I dont think I have any bugs I know of.. The IMPORTANT thing about ANY firmware upgrade is to make sure you NEED something in the update. There...

    AppleTV X - I am playing with something new

    Yes,, there are clear technical reasons for this. Temp drift of parts. Its important for any lab grade kind of gear to warm up at least 30 mins before use. This is improtant. Yes ALWAYS leave it on all the time. Well,,, most likely after months of use, like any modern device, it might need a...
