摘要： 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.

摘要： Methods and system for managing media clips over a data network. Media streams may be received over a data network and stored by a storage server. Metadata regarding the media streams may be generated and stored at a metadata server. A control station can retrieve media frames originating in the stored media streams from the storage server, based on metadata. Media frames from multiple media streams can be retrieved and displayed in synchronization, based on respective timecodes.

摘要： The described embodiments relate to methods and systems for detecting the blockiness of a video signal comprised of a number of pixels. The method includes the steps of determining if the pixel forms a part of at least one visible horizontal transition along a macroblock border, at least one visible vertical transition along a macroblock border, at least one flat area or at least one flat macroblock; calculating a horizontal border transitions count, a vertical border transitions count, a flat area count and a macroblock flat area count; and generating at least one blockiness indicator for the region of interest selected from the group consisting of a block border indicator, a flat area indicator and a flat block indicator, wherein the at least one blockiness indicator is based on at least one of the horizontal border transitions count, the vertical border transitions count, the flat area count and the macroblock flat area count.

摘要： Various embodiments are described herein for methods and systems for operating a video compression system. In one example embodiment, the method of operating a video compression system includes determining an encoding complexity limit for an encoding module within the video compression system, determining signal complexity of an input signal to the video compression system, comparing the encoding complexity limit to the signal complexity at an adaptive scaling module within the video compression system, and if the signal complexity is determined to be greater than the encoding complexity limit, manipulating the resolution of the input signal at the adaptive scaling module to generate an output signal.

摘要： Apparatus, systems and methods for receiving one or more input signals and providing output signals in various video, audio, data and mixed formats are described. One or more input processors receive the input signals. Each of the input processors provides one or more packetized signals corresponding to one or more of the input signals received at the input processor. Each output processor can receive one or more packetized signals and generate one or more output signals. The output signals correspond to one or more of the input signals, additional locally generated signals or data relating to the signals or any combination of such signals. Use of a packet router according to the invention allows input signals encoded as one set of packetized signals to be recombined to provide additional packetized signals incorporating the same or different combinations of the packetized signals.
