摘要： A system (10) for transferring digital data from one data bank to another. The system (10) is designed especially for transmitting audio/video signals in digital format from a central processing center (16) to a plurality of cable networks for viewing either instantaneously or in the future. The system (10) incorporates four processing units: a central processing unit (16), a transmission processing unit (18), a receiving processing unit (20), and a master processing unit (22). The central processing unit (16) includes a scripter computer (24) for receiving a video signal (26), converting it to a digital signal (30), and storing the digital signal (30). The transmission processing unit (18) includes a transmission computer (34) and associated transmission hardware (36). The transmission computer (34) will attach a checksum to the end of each packet of information to be sent, along with any other identifying and scheduling information related to that particular file. The transmission hardware (36) sends the data blocks to a satellite (40). The receiving processing unit (20) includes receiving hardware (46) and an associated receiving computer (48). The master processing unit (22) is comprised of at least a master computer (50), a plurality of slaves (54), and a matrix hardware (56).
