Abstract: Various embodiments are described herein for systems and methods that can be used to operate a media transmission network. In at least one embodiment, the media transmission network comprises a plurality of media processing devices configured to receive and process media streams based on control data. The media transmission network also comprises a controller coupled to the plurality of media processing devices and configured to generate a control signal for some or all of the media processing devices in the network. The controller is configured to determine the timing at which to transmit the control signal to a respective media processing device in order for the instructions in the control signal to be executed at the same time as the media data is received. The controller determines the transmission timing of each control signal by determining the latencies and delays of the network and the devices, such as, for example, network latency, processing delay, and/or control delay.

Abstract: Various embodiments are described herein for a radio frequency (RF) signal router. In one example embodiment, the RF router comprises a controller, an input stage, an intermediate stage and an output stage. The input stage includes RF input terminals, pre-processing circuit and input processors, where each RF input terminal receives an incoming RF signal, each pre-processing circuit processes the incoming RF signal based on its power level, and each input processor adjusts a power level of an input RF signal based on a first controller signal to generate a processed input RF signal. The intermediate stage comprises intermediate switch matrices coupled to a controller and input processors, and configured to route intermediate RF signals. The output stage comprises output processors coupled to the controller, where each output processor is configured to adjust a power level of an output RF signal based on a second controller signal and generate a processed output RF signal, and where the second controller signal corresponds to the first controller signal.
