Реферат: The apparatus (1) comprises an input unit (2) for receiving and converting an analogue video signal to digital form. A storing unit (5) stores the digital signal which is read by a first output unit (6) and relayed to a visual display unit (not shown); a second output unit (10) on command reads a stored video frame from the storing unit (5) and downloads the frame to a printer for printing. The storing unit (5) comprises a DRAM (15), and the digital video signal is written to the DRAM (15) alternately through input latches (16 and 17) for providing sufficient time to allow a DRAM row address to be changed in a line of the video signal.
