Master AD continues to answer questions. Is video on digital board the internal memory or does it translate like TV?
Look at the carrier attentively. You will not find a place for flash cards or receiving antenna. It turns out that the downloading of videos is not automated.
Digital board is a simple system unit. Video, displayable on the screen, stored on a hard drive of "computer", which is in the vicinity of the carrier.
Coordination, on / off of digital board or the changing of video occurs with the participation of a person. And poured a promotional video over the Internet.
