ABSTRACT:
An edit suite combines a vision mixer and digital video effects device. A routing matrix (100) is arranged on a back board and interconnected with a number of signal processing devices including two mixers, two effects devices and a key store. Video inputs are supplied from time base controllers (102-108). The matrix comprises a plurality of dedicated buses and each processing device selects an input from one of a number of buses and returns an output to a different bus where it can be selected for further processing by a different device.
