  • System for determining reliability of extracted data using localized graph analysis
    Patent number: 11714954
    Abstract: A webpage containing information to be extracted may undergo changes to a layout of elements that present the information. These changes could result in an inability to retrieve the information later. A first graph is determined that represents elements of a first version of a webpage at a first time. An element in the first graph for which information is being acquired is specified. A relevant portion of the first graph is designated that includes the element and immediate neighbors in the first graph. Later, a second version of the webpage is retrieved, and a second graph of that second version is determined. The relevant portion of the first graph is compared to the second graph. If a match is found, the information of interest is extracted from the specified element of the second graph. This allows extraction of information to proceed even if the layout of elements changes.

  • Method and system for operating a set-top-box
    Patent number: 10021365
    Abstract: A method for operating a set-top-box that supports 3D video content is disclosed. The method involves transmitting video content from an HDMI port of the set-top-box to a display device at a first resolution. The method also involves, in response to a change in the HDMI_Video_Format field or in the 3D_Structure field of an HDMI Vendor Specific InfoFrame, automatically switching to transmitting video content from the HDMI port of the set-top-box at a second resolution. The method also involves, after the switch to the second resolution, automatically switching back to transmitting video content from the HDMI port of the set-top-box at the first resolution in order to trigger a re-sync operation at the display device.
