It's the informal name of H.264/MPEG-4 Part 10 or AVC (Advanced Video Coding). MPEG-4 AVC is the most widely used video codecs in Blu-ray discs. It supports 4096x2304 pixels in resolution and up to 26.7 Mbps for bit rate. This is the optimized video codec for Blu-ray, which delivers high quality picture even at the low bit rate than MPEG-1 in VCD.
Besides used in Blu-ray discs, MPEG-4 AVC (H.264) codec is also widely adopted to stream online videos, such as YouTube, Vimeo, and the iTunes Store."
Anyway it's horrible as codec, all broadcast look artefacted, loose a lot of details and textures with minimal lateral motion, even when the camera itself it's fine. Creates banding instead of gradientes, and much more banding than fine 8 bits JPEG images. The best youtube video have all that.
Even Blu-Rays have artefacts and loss of textures and details. It had terrible shaddow details compared to most DVD, since the shadows always get more artefacts.
Nobody will convice me this technology it's true, good, with true HD details, cause a good deal of detail and tecture of it it's lost somehow.
And please don't tell me that I need to watch it 4 meter aways to do not see the defects, cause 4 meter you will not see much difference comparing 4K to 1080p.
About TV, all stores I went have the same issue. Many TVs had their own DEMO indvidual video running a 4K. It's like damn LCD PC monitor, you sit in fornt of it 90 degree, straight, and the center looks brigther than the side, so you move to one side, still straight, and the side got brighter than the center and than the other side. You turn 20 degree and the entire screen turns with a different contrast. Even the crap IPC tecxhnology have this issue, despite lie about stating it's free from distortions.
Pure lie, pure crap.I refuse to watch movies or even watch TV in this technology.
I only use a LCD (LED backlight) for PC cause I'm forced, since there is no 16:9 CRT monitor. But if I stop to think about I feel desire to do the same as Elvis did to his TV (shoot it). Luckly I don't have guns and don't loke guns...
OLDED TV are no solution. It's a lot more expansive, have a 50% lispam in comparissom, making it 4 more expansive for year of life use. It have burn in prob,ems and have inferior brightness capability.
HDR don't impress me, It looks like a Photoshop expanded Dynamica range image. Even HDR have white clipping when we increase contrast, despite need less contrast adjust to look not faded.
It's just a scam world of home video.
And the ecologic argument it's another scam. People replaced their CRT for much larger LCD TVs, and these hugher sizes take as much or more energy as the CRT TVs they had before.

And yes, there's a good chance all the TVs in the store looked bad. Stores usually split the signal to go to all the TVs, and that looks terrible.
