60 videos can be displayed, each 20
restricted to one display area but within these boundaries freely movable and scalable.
It is also possible to configure video in a way that it is freely movable and scalable on the whole display wall.
This is called distributed video. It consists of a group of Q

(2-4). A distributed video can be displayed freely movable and
scalable on the whole wall regardless on the different display areas. Also combinations between distributed
video and normal video are possible. E.g. one channel of a Q

of each O

be grouped to display one free movable distributed video, whereas the data of the other channels of the Q
