Abstract

A scalable multiviewer system including at least one communication circuit is described. The at least one communication circuit includes at least one input being associated with at least one data source. The at least one communication circuit further includes at least one output being associated with at least one data sink. The at least one communication circuit further includes at least one channel interface for an inter-circuit communication channel being configured to transfer data between the at least one communication circuit and at least one further communication circuit. The at least one communication circuit further includes a processing circuit being configured to receive an input signal from the at least one input. The processing circuit further is configured to selectively transmit the input signal to the at least one output or to the at least one channel interface based on at least one preset communication parameter. The at least one preset communication parameter is programmable via a communication bus of the multiviewer system. Further, a method for distributing data from at least one data source to several data sinks via a scalable multiviewer system is described.
