The apparatus includes a transmitter (1) and a receiver (2). Each includes a processor (10,20) with a hard disk (12,22) and a communications interface (15,25). The interfaces communicate across the digital access network (RN) with both parts containing communications modules with a predetermined protocol for transfer to disk. The receiver has a temporary memory store (26) which is used to communicate with the processor. An anti-virus module (220) within the temporary store contains information on viruses, for comparison with the incoming data and extraction of the uncontaminated data. |
