Definition

★4K（K＝1000） means the number of the horizontal pixels.

⇒ Four times the resolution of Full-HD

★2 kinds of 4K standard.

Visual influences human eyes

★The density of pixels ： PPI = √（H

In general, it is said that the resolution of human eyes is approximately 90 ppi at 1m distance.

Input / Transmission

★There are three kinds of input mainly. 3G-SDI / HDMI / Display Port

⇒ Various inputs are required by customer to connect various equipments.

★High bit rate is required. (4 times the data size of Full-HD)
