Abstract: An apparatus for the display and storage of television picture information by using a dynamic random access memory accessible from a computer. The apparatus includes an interface providing connection to the computer, an address modifying circuit, an address switching unit including a first input group connected to predetermined address lines of the address bus of the address generator and a second group connected to predetermined address lines of the interface, and a parallel to series converter. The inputs of the address modifying circuit being coupled to the output of the address switching unit to provide modified addresses for the memory when any of the input groups addresses the memory. The control inputs of the address switching unit and of the data switching unit are connected to a horizontal address line of the address bus associated with a horizontal address bit (X.sub.3) of low significance.
