[QUOTE="spcav, post: 1058888369, member: 1120"] Οι αλγόριθμοι είναι κοινοί σε δισκάκια / streaming. Δεν μιλάμε γενικά, μιλάμε απολύτως τεχνικά. Τώρα σοβαρά, θα κάνουμε κουβέντα για το αν υπάρχει διαφορα στην ποιότητα; Ενα πρόχειρο link [URL unfurl="true"]https://www.howtogeek.com/872777/why-even-1080p-blu-rays-are-better-than-4k-streaming-video/#:~:text=this%20particular%20feature.-,Blu%2Dray%27s%20Bitrate%20and%20Color%20Depth%20Advantage,highly%20compressed%204K%20video%20stream.[/URL] Ειδικα αυτό που λέει εδώ περιγράφει ακριβώς την αίσθηση που εχω στα περισσότερα streams: A 1080p Blu-ray disc typically has a much higher bitrate than a 4K compressed video stream. This means the Blu-ray can use more data to represent each frame, resulting in a clearer and more detailed image than the highly compressed 4K video stream. The extra data allows for a wider range of colors, more detail in the shadows and highlights, and less visible compression artifacts such as pixelation and blurring. You'll often hear of [URL='https://www.howtogeek.com/728797/what-is-black-crush-on-a-display/']"crushed" blacks[/URL] in compressed video, which refers to the loss of details in dark areas. Απο εκεί και πέρα, ξαναλέω, ο καθενας το «βλέπει» προφανώς διαφορετικά. [/QUOTE]
