Abstract: A system (e.g., NVMe controller) for managing access to a memory resource by multiple users may include memory storing function queue categorizations for function queues associated with each user, and circuitry to store and execute a multi-user arbitration algorithm that arbitrates access to the memory resource by the multiple users. The function queue categorizations assign a function category to each function queue associated with each user.

Abstract: A display management unit configured to provide a modified video signal for display on a target display over an electronic distribution network. The unit may access information regarding the target display and at least one input. The unit comprises a database interface configured to retrieve display characteristics corresponding to the information regarding the target display from a characteristics database, and a mapping unit configured to map at least one of tone and color values from the at least one input to corresponding mapped values based at least in part on the retrieved display characteristics to produce the modified video signal.

Abstract: Methods and systems for color grading video content are presented. A component (e.g. a frame, a shot and/or a scene) of the video content is designated to be a master component and one or more other components of the video content are designated to be slave components, each slave component associated with the master component. A master component color grading operation is performed to the master component. For each one of the slave components, the master component color grading operation is performed to the slave component and a slave color grading operation that is specific to the one of the slave components is also performed. Metadata, which form part of the video content, are created to provide indicators on to whether components of the video are designated as master or slave components.

Abstract: MEMS shutters are applied in displays and imaging devices. In a display, sensors may detect light from a light source that is back-reflected by a MEMS shutter and/or ambient light that enters through the MEMS shutter. The sensors may be used to monitor performance of the light source and/or ambient lighting conditions. In an imaging device, MEMS shutters may be applied to selectively block light to prevent overexposed areas within an image.

Abstract: A display management unit configured to provide a modified video signal for display on a target display over an electronic distribution network. The unit may access information regarding the target display and at least one input. The unit comprises a database interface configured to retrieve display characteristics corresponding to the information regarding the target display from a characteristics database, and a mapping unit configured to map at least one of tone and color values from the at least one input to corresponding mapped values based at least in part on the retrieved display characteristics to produce the modified video signal.

Abstract: A method and system for detecting and characterizing an input signal receive a signal having an in-phase (I) component and a quadrature-phase (Q) component. A first IQ sample of the signal is acquired at a first point in time, and a second IQ sample of the signal is acquired at a second point in time, Using one or more processors, a delayed complex conjugate multiply (DCM) is applied to the first IQ sample of the signal and the second IQ sample of the signal to produce a constant product having an in-phase (IC) component and a quadrature-phase (QC) component. A signal magnitude and a signal frequency are determined from the IC component of the constant and the QC component of the constant, using the one or more processors.

Abstract: A system and method for enhancing data coherency and potential of at least one metadata associated with a video data configured to operate in a visual dynamic range (VDR) format are detailed. One system embodiment employs a metadata framing structure which includes a header start of frame bit set, a packet type bit set, a configuration bit set, a variable depth configuration/metadata bit set, a header end of frame bit set, a timestamp bit set for specifying a frame delay count to apply the at least one metadata to the video data and a checksum check bit set. The at least one metadata is designed to embed within a code word guard bit position of at least one color channel of the video data and adaptable to embed within the VDR pipeline to enhance the quality of the video data.

Abstract: Architecture for slicing data defined on both tabular data sources and in OLAP (online analytical processing) multidimensional data sources by time relative to the current date simultaneously with the same time intelligence (TI) filter on a dashboard page. The architecture employs a simple time period specification (STPS) language used to specify time periods in monitoring server TI filters, and key performance indicator (KPI) filters. The architecture maps all time dimensions to a common set of time aggregations (hierarchy) and to a common calendar.
