  • Patent number: 10021457
    Abstract: A computerized method for engaging a user of a mobile computer system. The mobile computer system may be connectible to a server over a wide area network. An audio signal of ambient audio is autonomously sampled in the vicinity of the mobile computer system to capture one or more audio samples of the audio signal. The multiple samples of the audio signal are autonomously sampled without requiring any interaction from the user, thus avoiding an input from the user to capture each of the samples. The audio sample may be processed to extract an audio signature of the audio sample. The audio signature may be compared with multiple previously stored reference audio signatures. Upon matching the audio signature with at least one reference audio signature a matched reference audio signature may be produced.

  • Patent number: 9998513
    Abstract: A method, system and computer program product for selecting a bitrate to stream encoded media. A manifest file is fetched, where the manifest file contains metadata for encoded media segments which includes tags signifying the associated encoded media segments being important to the viewer. A playback occupancy level is then increased before reaching these tagged media segment(s). A high bitrate (high quality) is selected to stream the tagged media segment(s) which are then fetched and played at the selected high bitrate in response to the new playback buffer occupancy level being above a threshold level. In this manner, those media segments that are of higher importance to the viewer will be viewed in a higher quality since content information is used to select the bitrate to receive the encoded media segments. As a result, the user's quality of experience in viewing media is improved.

  • Patent number: 9984728
    Abstract: Various embodiments identify differences between frame sequences of a video. For example, to determine a difference between two versions of a video, a fingerprint of each frame of the two versions is generated. From the fingerprints, a run-length encoded representation of each version is generated. The fingerprints which appear only once (i.e., unique fingerprints) in the entire video are identified from each version and compared to identify matching unique fingerprints across versions. The matching unique fingerprints are sorted and filtered to determine split points, which are used to align the two versions of the video. Accordingly, each version is segmented into smaller frame sequences using the split points. Once segmented, the individual frames of each segment are aligned across versions using a dynamic programming algorithm. After aligning the segments at a frame level, the segments are reassembled to generate a global alignment output.

  • Patent number: 9916125
    Abstract: Method and systems are provided for identification of device groups in a network. In an example implementation, a first playback device receives, from a second playback device, first data indicating a first group identification corresponding to a zone group, the zone group including the first playback device and the second playback device, and the second playback device operating as a group coordinator of the zone group. After receiving the first data, the first playback device receives a message indicating that the second playback device is leaving the zone group. In response to receiving the message, the first playback device determines a second group identification corresponding to the zone group and after determining the second group identification, transmits, over to at least one controller device configured to control at least the first playback device and the second playback device, second data indicating the second group identification.
