The invention relates to a method and a device (50) for transferring data between an open computer network (2) and a closed computer assembly (1). For this purpose, first image and/or audio data (VD1, AD1) of a computer (3) of the open computer network (2) is recorded in a previously precisely reserved first transfer memory region (16U, 13U) of a memory that is connected to the open computer network (2). The first image and/or audio data (VD1, AD1) is read by means of a data-copying unit (11) via uni-directional memory access (20) from the first transfer memory region (16U, 13U). On the basis of this, second image and/or audio data (VD2, AD2) is generated, each representing an image that is defined by the first image and/or audio data (VD1, AD1). The second image and/or audio data (VD2, AD2) is then passed on to the closed computer assembly (1). |
