1. A system for routing an input serial digital interface (SDI) signal from an input SDI port to an output SDI port, the system comprising:
at least one input card coupled to the input SDI port;
at least one output card coupled to the output SDI port;
a midplane coupled to the at least one input card and the at least one output card; and
a controller coupled to the midplane configured to:
determine addressing rules, the addressing rules corresponding to a destination address for the input SDI signal;
generate a control signal corresponding to the addressing rules; and
transmit the control signal to the midplane;
the at least one input card being configured to:
receive the input SDI signal at the input SDI port;
process the input SDI signal to generate one or more packetized media streams, each packetized media stream comprising a plurality of packets, wherein each packet has a packet header comprising a source address corresponding to that packetized media stream; and
transmit each packetized media stream from an IP output port to the midplane;
the midplane being configured to:
identify the source address corresponding to each packet of a packetized media stream;
update the corresponding packets of each packetized media stream with a destination address based on the control signal from the controller, and generate a corresponding processed packetized media stream; and
route the processed packetized media stream to an output card based on the destination address; and
the output card being configured to:
receive one or more processed packetized media streams at an input IP port;
process the one or more processed packetized media streams to generate a corresponding output SDI signal; and
providing the output SDI signal at the output SDI port.
