    Abstract: Page layout of web content is performed based on templates. Publishers publish web content referred to as “sources.” Each source comprises one or more assets from one or more asset types. The asset types include title, subtitle, byline, dateline, pull quote, image, video, audio, caption, and in-line text. A content processing system processes the sources using a conversion module and a rule database. The conversion module restructures a received source into a standardized format of the source, wherein each asset of the source is tagged with an asset type according to rules present in the rule database. A layout module interprets the standardized source, determines one or more templates from a template database to use for the layout of the assets of the source, and lays out the assets of the source based on the selected templates.

  • Patent number: 9870375
    Abstract: Various embodiments relating to reducing memory bandwidth consumed by a continuous scan display screen are provided. In one embodiment, scoring criteria are applied to a reference image of a first image format having a first bit depth to generate an image conversion score. The scoring criteria are based on a histogram of one or more characteristics of the reference image. If the image conversion score is greater than a threshold value, then the reference image is converted to a modified image of a second image format having a second bit depth less than the first bit depth, and the modified image is scanned onto the continuous scan display screen. If the image conversion score is less than the threshold value, then the reference image is scanned onto the continuous scan display screen.

  • Patent number: 9866789
    Abstract: A smart multimedia content receiver automatically resizes video images based on the content being displayed on the TV screen. Such a self-formatting content receiver includes on-board image processing capability that provides continuous video analysis to detect changes in program formatting and convert each frame as it is received in real time, as opposed to processing and re-releasing an entire program or movie, or relying on the viewer to re-format programs manually. In response to detecting a change, aspect ratio adjustments are made as needed. Because the self-formatting content receiver has access to the video data before it is displayed, such automatic on-the-fly adjustments ensure that the viewer's experience during program changes is seamless and without distortion. Subscribers can influence decisions made by the content receiver by pre-setting viewer preferences for aspect ratio adjustment.

  • Patent number: 9800857
    Abstract: A video coder scales a motion vector of a current prediction unit (PU) of a current picture in order to compensate for a difference in temporal distance. In addition, the video coder determines a predictive block for the current PU, determines a disparity reference block based on samples of the disparity reference picture at a location indicated by a disparity vector of the current PU, and determines, based on samples of the fixed reference picture at a location indicated by the scaled motion vector, a temporal-disparity reference block for the current PU. The video coder then determines a residual predictor for the current PU. Each sample of the residual predictor for the current PU indicates a difference between a sample of the temporal-disparity reference block for the current PU and a corresponding sample of the disparity reference block.
