  • Publication number: 20190132641
    Abstract: A client device accesses a video input stream from an intermediate device for display. The client device analyzes the video input stream to determine that the video input stream matches a template indicating a change of speed. In some example embodiments, the analysis is performed while the client device is generating a video output stream that replaces video content received from a content source via the intermediate device. Based on the video input stream matching the template, the client device modifies the video output stream to show the change of speed. For example, commercials transmitted from a national content provider to a smart TV via a set-top box may be replaced with targeted commercials. During the replacement, fast-forwarding of the commercial may be detected by matching a template with the video input stream. While the video input stream is being fast-forwarded, the smart TV fast-forwards the targeted commercial.

  • Patent number: 10185718
    Abstract: A machine can compress an entry of an index, starting with accessing first data that corresponds to a segment of content and is expressed in a first number of bits. The machine classifies the content into a first class or a second class and generates second data that is expressed in a fewer, second number of bits. To generate an upper portion of the second data, the machine selects and executes one of two algorithms based on the class of the content. The machine then assigns the generated second data to the segment. To decompress the second data and thereby recover the first data, the machine parses upper and lower portions of the second data, determines the class of the content, and recovers upper and lower portions of the first data. The upper portion is recovered via one of two algorithms based on the class of the content.

  • Patent number: 10136183
    Abstract: A client device accesses a video input stream from an intermediate device for display. The client device analyzes the video input stream to determine that the video input stream matches a template indicating a change of content source. The analysis is performed while the client device is generating a video output stream that replaces video content received from a content source via the intermediate device. Based on the video input stream matching the template, the client device ceases replacement of the video input stream. The client device continues to analyze the video input stream and determines that the video input stream matches a second template indicating a return to the original content source. Based on the video input stream matching the second template, the client device resumes replacement of the video input stream.

  • Patent number: 10123073
    Abstract: A client device accesses a video input stream from an intermediate device for display. The client device analyzes the video input stream to determine that the video input stream matches a template indicating a portion of the video input stream that is created by the intermediate device. Based on the video input stream matching the template, a video output stream generated by the client device is modified to include the portion of the video input stream generated by the intermediate device. For example, commercials transmitted from a national content provider to a smart TV via a set-top box may be replaced with targeted commercials. During the replacement, informational messages or menus generated by the set-top box may be detected and the replacement video altered by the smart TV to include the messages or menus generated by the set-top box.

  • Patent number: 9959345
    Abstract: Methods and systems for searching for and retrieving video content via fingerprint matching are described. In some example embodiments, the methods and systems access an index of reference fingerprints, such as quantized values associated with multiple values calculated from patches of a frame, that are associated with sequential frames of known video content. The methods and systems may receive a search query that includes a group of query fingerprints associated with sequential frames of video content presented at a client device, access the index, compare the group of query fingerprints to reference fingerprints of the index, determine that the group of query fingerprints match the reference fingerprints of the index, and identify the video content presented at the client device based on the determined match.

  • Publication number: 20170180792
    Abstract: A client device accesses a video input stream from an intermediate device for display. The client device analyzes the video input stream to determine that the video input stream matches a template corresponding to a screen portion. Based on the video input stream matching the template, a video output stream is generated and caused to be presented on a display. In some example embodiments, the analysis is performed while the client device is replacing video content received from a content source via the intermediate device. For example, commercials transmitted from a national content provider to a smart TV via a set-top box may be replaced with targeted commercials. During the replacement, menus generated by the set-top box may be detected and the replacement video altered by the smart TV to include the menus.

  • Publication number: 20170180793
    Abstract: A client device accesses a video input stream from an intermediate device for display. The client device analyzes the video input stream to determine that the video input stream matches a template indicating a semi-transparent overlay. Based on the video input stream matching the template, a video output stream is generated and caused to be presented on a display. In some example embodiments, the analysis is performed while the client device is replacing video content received from a content source via the intermediate device. For example, commercials transmitted from a national content provider to a smart TV via a set-top box may be replaced with targeted commercials. During the replacement, semi-transparent menus generated by the set-top box may be detected and the replacement video altered by the smart TV to include the menus.

  • Patent number: 8472289
    Abstract: A method and system is provided for doing compact disc TOC look-ups cheaply and efficiently by using a special indexing mechanism particularized to TOC look-ups. The indexing scheme allows a successful search of TOCs using as few as 2 disk seeks in contrast to the usual hundreds of disk seeks required by a general purpose indexing scheme. This performance improvement is achieved by using a static database of TOCs in a read-only implementation so that the data organization and code for lookups can be optimized without regard for any updates to this data at a later time. The index data structure is arranged in a fashion that allows for seek-less, linear scans of index information once the proper scan location in the index has been identified.
