    Abstract: Techniques, described herein, may enable a computing device (e.g., a set-top-box, a user equipment (UE), etc.) with an array of sensors (e.g., microphones, antennas, etc.) to engage in beamforming in a manner that optimizes the signal strength of the target signal. For example, the computing device may create an optimized beam pattern by applying a pre-selected band width to a steering direction of the target signal. The beam width may include steering vectors at equal, angular distances from the steering direction, enabling steep transition slopes to be applied to the optimized beam pattern. In some implementations, the beam width and transition slopes may be standardized, such that the optimized beam pattern for any signal may be uniform, regardless of variables such as frequency and time.

    Abstract: A method, a system, and a non-transitory storage medium provides to store first recording information that indicates programs that are recorded and stored at user devices, and programs to be recorded and stored at the user devices, receive, from a user device, a message that includes second recording information, wherein the second recording information includes second data instances; compare a portion of the first recording information with the second recording information; determine whether there is a difference between each first data instance relative to each corresponding second data instance; determine a master source for each first data instance that differs from each corresponding second data instance; update each first data instance that differs, one of the network device or the user device based on the master source, and provide the DVR service based on an updated portion of the first recording information, an updated second recording information, or both.

    Abstract: A device may receive an audio sample, and may separate the audio sample into multiple sub-band signals in multiple frequency bands. The device may modify an upper boundary and a lower boundary of at least one of the frequency bands to form modified frequency bands. The device may modify the sub-band signals to form banded signals associated with the modified frequency bands. The device may smooth the banded signals to form smoothed signal values. The device may identify peak values included in the smoothed signal values, and may generate an audio fingerprint for the audio sample based on the smoothed signal values and the peak values.
