Abstract: A digital data display in which each display unit includes a RAM character definition buffer store and a screen buffer. The character definitions and screen buffer for each picture to be displayed are constructed in a remote host central processing unit. In order to minimise the time that a user has a blank screen the character definition and screen buffer data is sent from the c.p.u. to the display unit in groups relating to rows of character cells on the screen, then a coherent picture is displayed growing from the top downwards, giving a roller blind effect. Data relating to the first significant row is sent initially followed by groups of character definitions and screen buffer data, the size of the groups dependent upon the characteristics of the transmission buffer.
