Abstract: A system and method are provided for controlling data distribution in a network (108, 109). The network has data-generating and data-receiving devices (101, 102, 103, 105, 106, 111, 112, 113, 116, 117, 118, 206). The system includes memory means (209), processing means (203), networking means (212), at least one input controller (404) and at least one output controller (404). The memory means (209) stores instructions (402) which configure said processing means (208) to identify data-generating devices (101, 102, 206, 111, 112 113) and data-receiving devices (103, 105, 106, 107, 116, 117, 118) in said network. The identified devices (102, 103, 105, 106, 111, 112, 113, 116, 117, 118, 206) are initialised across said network by way of said input controller (404) and one output controller (404). Input data (405, 406) is controlled by said input controller (404). Output data (407, 408) is controlled by said output controller (404). Control is performed selectively according to user input (409).
