  • Publication number: 20210126854
    Abstract: Systems and methods for a path selection by a network router are disclosed. The router receives a data packet destined to travel a current path, as identified by a packet header, to a destination router. The router determines whether the current path is the best path of a set of network paths for the data packet to travel to reach the destination router based on telemetry characteristics of a set of network paths. The telemetry characteristics include a bandwidth availability estimate that is a function of one or both of a corresponding path throughput and a corresponding path packet loss rate. In response to determining the current path is not the best path, the router chooses a best path based on the telemetry characteristics of the set of paths and replaces the current path with the best path for travel by the data packet to the destination router.

  • Publication number: 20210120253
    Abstract: A disclosed configuration includes a system (or a computer implemented method or a non-transitory computer readable medium) for automatically preprocessing higher dynamic range image data into lower dynamic range image data through a data adaptive tuning process. By automatically preprocessing the higher dynamic range image data into the lower dynamic range image data through the data adaptive tuning process, an existing encoding process for encoding the standard dynamic range image data can be applied to the lower dynamic range image data while preserving metadata sufficient to recover image fidelity even in the high dynamic range. In one aspect, the system (or a computer implemented method or a non-transitory computer readable medium) provides for backwards compatibility between high dynamic range video services and existing standard dynamic range services. In one aspect, regrading is applied in a domain that is perceptually more uniform than the domain it is initially presented.

  • Publication number: 20210099715
    Abstract: Video quality analysis may be used in many multimedia transmission and communication applications, such as encoder optimization, stream selection, and/or video reconstruction. An objective VQA metric that accurately reflects the quality of processed video relative to a source unprocessed video may take into account both spatial measures and temporal, motion-based measures when evaluating the processed video. Temporal measures may include differential motion metrics indicating a difference between a frame difference of a plurality of frames of the processed video relative to that of a corresponding plurality of frames of the source video. In addition, neural networks and deep learning techniques can be used to develop additional improved VQA metrics that take into account both spatial and temporal aspects of the processed and unprocessed videos.

    Abstract: A compressor includes a compressor housing containing a compressor wheel and defining an inlet duct that leads air into the compressor wheel, and a wheel shroud located adjacent the blade tips and extending upstream from the blades. An annular space is defined between the wheel shroud and an inner surface of the inlet duct. The wheel shroud defines a bleed port that extends into the annular space to bleed a portion of the air entering the compressor wheel into the annular space to be recirculated back into the main flow. A noise attenuator for attenuating compressor blade passing frequency noise is formed as a blind slot located opposite the bleed port and extending for a length L from the radially inner surface of the inlet duct toward the radially outer surface of the inlet duct.

  • Publication number: 20210014497
    Abstract: A video coding system in which video images of a video bitstream are rescaled prior to encoding, and again at the decoder upon reception. When encoding a given video frame, the video encoder deduces a level of resampling to apply to a reference frame in order to properly predict blocks in the given video frame or the full given video frame, and carries out one or more predictions by first applying a resampling process on the reference frame data at the deduced level. To decode the given video frame of the bitstream, a video decoder compares a size of the given video frame to sizes of a reference frame to determine a level of resampling for the reference frame data, and carries out predictions to generate predicted data by first applying the determined level of resampling to the reference frame data.
