Hi everyone, welcome to another blog from the no 1 video company Durban. Today I would like to talk about 4 K vs H D, how has the progression been in the year 2019?
Lets start off with what is 4 K? Basically in a nutshell 4 K is HD x 4
The above diagram explains the resolution of 4 K vs HD
Top of the image left hand side shows the size taken by DVD, 720 lines of resolution by 480 lines of resolution. the next size is HD 720p, this is the smaller HD screen size, in South Africa DSTV broadcasts in 720 p H D. This gives us an idea of why 4K in South Africa can still be early days, SA is not even close to broadcasting in 4 K, and even though TVs are 4K quality they very seldom playing in 4 K mode. TV in SA is not 4 K, Blu Ray DVD is not 4 K. Even seldom are you playing a video on Youtube because of bandwidth required to play 4 K
Netflix suggests bandwidth of between 15 mbs to 25 mbs to support 4K broadcast. There isn’t many homes with that amount of bandwidth are out there. And that also means not having any other devices using the bandwidth.
This means the 4 K resolution is maybe too high for South African viewers right now in 2019.
