    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...
