Challenging sentence edit

Latest comment: 1 year ago1 comment1 person in discussion

Here's a single sentence from the article expanded out in bullet form:

Research of DSC using the ISO/IEC 29170 interleaved protocol

in which an uncompressed reference image is presented side by side

with a rapidly alternating sequence of
compressed test image

uncompressed reference image

performed with various types of images
people

natural and man-made scenery

text

known challenging imagery

shows that

for most images

DSC satisfies the standard's criterion for visually lossless performance

although
in some trials

participants were able to detect the presence of compression

on certain images

That's too much to pack into one sentence, IMO. — MaxEnt 14:24, 17 January 2023 (UTC)Reply

So what compression Ratio is possible with DSC? edit

Latest comment: 2 months ago1 comment1 person in discussion

At the end: What compression ratio is possible? For example with DSC and Displayport 2.1 ? Is 8k 240Hz possible with DP 2.1 and DSC (on 10Bit with 4:4:4)? What is maximum for DP 2.1 with DSC on these Settings ?

Second: It's "visually lossless". Ok, it is described, what that means. But not clear enough. I mean, i guess, on a higher compression ratio, it's more visible than on low ratios. So for what compression ratio is this 75% claim ? 2A02:1210:8CF9:D100:D9A5:FB86:AC84:9418 (talk) 15:16, 21 February 2024 (UTC)Reply
