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: Embodiments here broadly relate to a system which allows for flexibly, and adaptively, accommodating for various analog and digital streams. In one example case, the system can accommodate for the use of both legacy modems as well as newer digital modems. The system may not require the use of complex and expensive, very high data rate and/or very high throughput wideband digital switches in some architectures, as well as potentially eliminating the need for some additional processing equipment found in traditional architectures (i.e., wideband signal processors (WSP), legacy modem data converts (LDMCs), etc.).

Abstract: The present disclosure generally relates to multi-stage digital converters, including multi-stage digital down-converters (DDCs) and multi-stage digital up-converters (DUCs). In at least one example, the multi-stage digital down converter (DDC) comprises a plurality of stages, each stage comprising a frequency mixer and a decimation filter, and at least one controller coupled to one or more of the plurality of stages and operable to control one of the frequency mixer and decimation filter. In another example, the multi-stage digital up converter (DUC) comprises a plurality of stages, each stage comprising a frequency mixer and interpolation filter; at least one controller coupled to one or more of the plurality of stages and operable to control one of the frequency mixer and the interpolation filter.

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.
