  • Patent number: 10788392
    Abstract: Conduit leakage detection system and method are provided. The system includes a first detection unit, a processor, and a memory. The first detection unit includes a first transceiver and a second transceiver communicates with the first transceiver to detect a conduit. The first transceiver sends a first probe signal toward a first direction, and the second transceiver is configured to receive the first probe signal. The memory stores a first preset channel state information (CSI), and the first preset CSI including a first CSI and a first normal CSI. The processor obtains a first current CSI from the first probe signal by performing a time-reversal process, and compares the first current CSI to the first preset CSI. When the first CSI is matched to the first current CSI, a first conduit leakage event associated with the conduit is determined to be occurred.

  • Patent number: 10743007
    Abstract: A video data stream is rendered reducible in a manner so that the reduction leads to a restriction of pictures of the reduced video data stream to merely a predetermined subarea of the pictures of the original video data stream and in a manner so that transcoding, such as re-quantization, may be avoided and a conformance of the reduced video data stream relative to the codec underlying the original video data stream be maintained. This is achieved by providing the video data stream with information including an indication of the predetermined subarea and replacement indices for redirecting the indices included by the payload portion so as to refer to, and/or replacement parameters for adjusting the first set of coding parameter settings so as to result in, a second set of coding parameter settings.

  • Patent number: 9392061
    Abstract: A highly predicable quality shared distributed memory process is achieved using less than predicable public and private internet protocol networks as the means for communications within the processing interconnect. An adaptive private network (APN) service provides the ability for the distributed memory process to communicate data via an APN conduit service, to use high throughput paths by bandwidth allocation to higher quality paths avoiding lower quality paths, to deliver reliability via fast retransmissions on single packet loss detection, to deliver reliability and timely communication through redundancy transmissions via duplicate transmissions on high a best path and on a most independent path from the best path, to lower latency via high resolution clock synchronized path monitoring and high latency path avoidance, to monitor packet loss and provide loss prone path avoidance, and to avoid congestion by use of high resolution clock synchronized enabled congestion monitoring and avoidance.

  • Patent number: 9325985
    Abstract: Devices and methods for determining image quality using full-reference and non-reference techniques. Full reference image quality may be determined prior to output of an image or video frame from an image sensor processor by temporarily retaining image data from the image sensor and comparing processed image data of the image to the retained, non-processed image data of the same image. Full reference image quality determination may be assisted by a heuristic-based fault indicator. Image quality may also be determined by a non-reference technique of matching the image to one of various scenarios that are associated with sets of heuristics and applying the heuristics of the particular scenario to the image. Instead of relying on a nominal frame rate, video timing quality may be determined by comparing the capture time interval between successive video frames to the presentation time interval of the same video frames.

  • Patent number: 9232217
    Abstract: A method for assessing the quality of a transmitted video signal sequence at a receiver side includes: capturing the input video bit stream; extracting at least one feature or a set of features; determining the continuous probability of visibility for each packet loss event which occurred within a specific time interval; and employing the continuous probability of packet loss visibility as a weighting factor of the at least one feature or set of features extracted from the video bit stream to calculate an estimate of the overall quality, Q, of the transmitted video sequence.

  • Patent number: 9049420
    Abstract: A relative quality score is provided that takes into account properties of an encoded version of a source video. For example, one such quality score calculates a difference of higher and lower quality transcoded versions of the source video, and computes quality metrics for each to evaluate how similar the transcoded versions are to the source video. A relative quality score quantifying the quality improvement of the high-quality version over the low-quality version is computed. The relative quality score is adjusted based on a measurement of the quality of the source video. If the relative quality score for the video indicates a sufficient quality improvement of the high-quality version over the low-quality version, various actions are taken, such as retaining the high-quality version, and making the high-quality version available to users, e.g. via a video viewing user interface.

  • Patent number: 9038119
    Abstract: A handheld leakage detector for finding digital signal leaks in a HFC network, comprises a radio receiver, a leakage receiver, leakage sampler, a correlator, and a display. The radio receiver receives samples of the digital signal taken from the HFC network, called “reference samples.” The leakage receiver receives a leakage signal, which is a leaked version of the digital signal from the HFC network. The leakage sampler samples the leakage signal to form leakage samples. The correlator performs a cross-correlation of the reference samples and the leakage samples, to produce a correlation function. An optimizable value is determined from the correlation function. The value generally becomes more optimized as the detector approaches the leak. The leak is sought by iteratively changing the position of the detector until the value becomes substantially optimized or the leak is found.

  • Publication number: 20150130952
    Abstract: A method and system that assesses video quality of transmitted video packet signals suffering from packet loss and delay. This packet loss and delay can create freeze events, which are observed as a jerkiness while viewing the video. The system and method compares the frames in a video transmission to determine freeze events; extracts a set of features from the locations of the freeze events and decoded video frames; and maps the set of features into a video quality score using a neural network. The video quality score provides an assessment of the effects of irregular frame freezes due to packet loss or delay on the quality of the video.

  • Patent number: 9007467
    Abstract: The invention pertains to a method for operating an image-processing device in which an image signal on which a noise signal is superimposed is digitally transmitted between a transmitter and at least one receiver, and in which the image signal comprises a timed sequence of images, each containing its own image content and a noise pattern of the noise signal superimposed on the image content. At least certain areas of at least two successive images of the image signal are compared to each other after the transmission, and if a difference is found between the noise patterns contained in the images, it is concluded that the images have been transmitted successfully even if the image content of the images is identical. The invention also pertains to an image-processing device for the digital transmission of an image signal on which a noise signal is superimposed.
