  • Patent number: 10553235
    Abstract: A method for controlling a speech enhancement process in a far-end device, while engaged in a voice or video telephony communication session over a communication link with a near-end device. A near-end user speech signal is produced, using a microphone to pick up speech of a near-end user, and is analyzed by an automatic speech recognizer (ASR) without being triggered by an ASR trigger phrase or button. The recognized words are compared to a library of phrases to select a matching phrase, where each phrase is associated with a message that represents an audio signal processing operation. The message associated with the matching phrase is sent to the far-end device, which is used to configure the far-end device to adjust the speech enhancement process that produces the far-end speech signal. Other embodiments are also described.

  • Patent number: 10140359
    Abstract: A distributed database management system provides a central database resident on a server that contains database objects. Objects, e.g., program guide data, to be replicated are gathered together into distribution packages called “slices,” that are transmitted to client devices. A slice is a subset of the central database which is relevant to clients within a specific domain, such as a geographic region, or under the footprint of a satellite transmitter. The viewer selects television programs and Web content from displayed sections of the program guide data which are recorded to a storage device. The program guide data are used to determine when to start and end recordings. Client devices periodically connect to the server using a phone line and upload information of interest which is combined with information uploaded from other client devices for statistical, operational, or viewing models.

  • Patent number: 10045050
    Abstract: A perceptual filter may be implemented to filter one or more spatial frequencies from a video signal that are below a contrast sensitivity limit of a viewer of the video signal. The perceptual filter may be configured to adapt one or more perceptual filter parameters on a pixel-basis based on, for example, content, viewing distance, display density, contrast ratio, display luminance, background luminance, and/or age of the viewer. A spatial cutoff frequency of the perceptual filter may be mapped to a contrast sensitivity. The perceptual filter may be used as a preprocessing step for a video encoder so as to lower an encoded bitrate. Temporal filtering of the video frames may be used to maintain continuity of a spatial cutoff frequency to ensure the perceptual filtering effects are not identified as motion by a video encoder, and the temporal filtering may be restricted to static areas of a frame.

The video coding components may include intra-prediction modes, discrete cosine transform (DCT) coefficients, motion information, or combinations thereof, and may be used as a basis for objectively predicting a Quality of Experience (QoE) or Motion Opinion Score (MOS) score of the degraded bit-stream.

    Abstract: According to one embodiment, an electronic device receives a broadcast signal includes a high-speed transmission channel and a low-speed transmission channel. The electronic device estimates a CN when the electronic device is in an environment corresponding to a stationary state, based on a measured reception power, reception sensitivity required for receiving a broadcast service of the high-speed transmission channel and a necessary CN required for receiving the broadcast service of the high-speed transmission channel, and controls a processing of switching a demodulation target between the high-speed transmission channel and the low-speed transmission channel, based on a difference between the estimated CN and the measured CN.

  • Publication number: 20130222608
    Abstract: An imaging sensor is signaled to capture a digital image of a dark scene. For each of the pixel columns in the image, a respective column value is computed that represents at least some of the pixels in the column. For each of the pixel columns in the image, a respective comparison is made between the respective column value of the pixel column and a reference value. A respective column score is computed, for each of the pixel columns, based on the respective comparison. An indication that identifies one or more of the pixel columns as anomalous is stored, when the respective column score of the one or more the pixel columns does not meet a criterion. Other embodiments are also described and claimed.

    Abstract: A method for creating and displaying points of interest in video test results comprises obtaining a plurality of video test results, each of the plurality of video test results corresponding to a tester, and for each of the plurality of video test results, displaying the video test results, receiving at least one indicator of a point of interest in the video test results, receiving a text comment associated with the point of interest, and saving a timestamp that indicates a position in the video test results of the point of interest and a text comment in a memory. Then a graphical user interface is created that displays the timestamp and text comment of each point of interest in the plurality of test video results, where selection of a point of interest causes the corresponding video test result to be displayed beginning at the timestamp of the selected point of interest.

  • Publication number: 20130128055
    Abstract: A system includes a content evaluation device is configured to receive reproduced media content and compare the reproduced media content to reference media content to determine a quality of the reproduced media content relative to the reference media content. The content evaluation device is configured to apply an entropy factor to the determined quality to model human perception of the reproduced media content. A method of determining the entropy factor includes converting the reference media content or the reproduced media content to a grayscale image, counting a number of unique luminance values in the grayscale image, determining the total number of possible luminance values, and defining the entropy factor to be the number of total pixels compared relative to the maximum number of pixels represented by any single luminance value multiplied by the number of possible luminance values.
