  • Patent number: 8805683
    Abstract: An audio recognition service recognizes an audio sample across multiple content types. At least a partial set of results generated by the service are returned to a client while the audio sample is still being recorded and/or transmitted. The client additionally displays the results in real-time or near real-time to the user. The audio sample can be sent over a first HTTP connection and the results can be returned over a second HTTP connection. The audio recognition service further processes check-in selections received from the client for content items indicated by the results. Responsive to receiving the check-in selections, the service determines whether a user is eligible for a reward. If the user is eligible, the service provides the reward.

  • Patent number: 8806215
    Abstract: Methods and systems for robust watermark insertion and extraction for digital set-top boxes are disclosed and may include descrambling, detecting watermarking messages in a received video signal utilizing a watermark message parser, and immediately watermarking the descrambled video signal utilizing an embedded CPU. The embedded CPU may utilize code that may be signed by an authorized key, encrypted externally to the chip, decrypted, and stored in memory in a region off-limits to other processors. The video signal may be watermarked in a decompressed domain. The enabling of the watermarking may be verified utilizing a watchdog timer. The descriptors corresponding to the watermarking may be stored in memory that may be inaccessible by the main CPU. The watermark may comprise unique identifier data specific to the chip and a time stamp, and may be encrypted utilizing an on-chip combinatorial function.

  • Patent number: 8805809
    Abstract: According to one embodiment, an apparatus stores a plurality of datapoints. A datapoint comprises a first value and a second value that depends upon the value of the first value. The apparatus associates the datapoint with a group from a plurality of groups. The group is associated with an identifying range and the datapoint is associated with the group based at least in part upon the first value of the datapoint and the identifying range of the group. The apparatus calculates a median of the second values of the datapoints associated with the group and a performance value by performing a regression based at least in part upon the identifying range and the calculated median of the group. The apparatus determines that the performance value exceeds a baseline value and in response, presents, on a display, an illustration depicting the identifying range and the associated median of the group.

  • Patent number: 8803906
    Abstract: A video receiver receives a compound transport stream (TS) comprising 3D program video streams and spliced advertising streams. The received one or more 3D program video streams are extracted and decoded. Targeted advertising streams are extracted from the received advertising streams according to user criteria. Targeted advertising graphic objects of the extracted or replaced targeted advertising streams are spliced into the decoded 3D program video streams. The decoded 3D program video with the spliced targeted advertising graphic objects is presented in a 2D video. The extracted or replaced targeted advertising streams are processed to generate the targeted advertising graphic objects to be spliced based on focal point of view. The generated targeted advertising graphic objects are located according to associated scene graph information. The decoded 3D program video streams and the spliced targeted advertising graphic objects are converted into a 2D video for display.

  • Patent number: 8806377
    Abstract: A method and system for providing a graphical user interface with contextual views. In various embodiments, the present invention provides a graphical user interface that allows the changing contents of a global menu in the graphical display based upon the selected nodes that belong to a hierarchical chart. Only those actions applicable (contextual) to the selected nodes will be determined and displayed in the menu. Accordingly, the contents of the selectable options are updated based upon the selected nodes. When more than one node is selected, the displayed selectable actions are an intersection of the actions permitted for each selected node. In a specific embodiment, a comparison menu is provided to allow the user to be able to compare unique corresponding properties of selected nodes.

  • Patent number: 8802469
    Abstract: A method for the separation of multiple dies during semiconductor fabrication is described. On an upper surface of a semiconductor wafer containing multiple dies, metal layers are deposited everywhere except where a block of stop electroplating material exists. The stop electroplating material is obliterated, and a barrier layer is formed above the entire remaining structure. A sacrificial metal element is added above the barrier layer, and then the substrate is removed. After the semiconductor material between the individual dies is eradicated, any desired bonding pads and patterned circuitry are added to the semiconductor surface opposite the sacrificial metal element, a passivation layer is added to this surface, and then the sacrificial metal element is removed. Tape is added to the now exposed barrier layer, the passivation layer is removed, the resulting structure is flipped over, and the tape is expanded to separate the individual dies.
