1. A system of managing media streams over an IP network, the system comprising:
a first device configured to:
extract a first instruction from a first control signal;
process a received media stream based on the first instruction to generate a transformed media stream;
transmit the transformed media stream to a second device;
the second device coupled to the first device and the second device being configured to:
receive the transformed signal from the first device;
extract a second instruction from a second control signal; and
process the transformed media stream based on the second instruction; and
a controller coupled, over the IP network, to the first device and the second device, the controller being synchronized with the first device and the second device, wherein the controller is configured to:
generate the first control signal, wherein the first control signal includes instructions for the first device;
determine a first time of transmission of the first control signal to the first device such that the first control signal is received by the first device simultaneously with the received media stream;
transmit the first control signal at the first time of transmission to the first device;
generate the second control signal, wherein the second control signal includes instructions for the second device; and
determine a second time of transmission of the second control signal to the second device such that the second control signal is received by the second device simultaneously with the transformed media stream.
