    Abstract: Systems and methods are described for streaming content to multiple devices from a shared sliding window buffer in kernel space, thereby reducing memory resource use and minimizing context/mode switching between kernel space and user space. For example, concurrent streaming sessions may be seen, e.g., as a live multimedia stream. If a live video is being transmitted as a multicast stream to many devices, rather than each device having a corresponding sliding window buffer in kernel space, each device will share a shared sliding buffer in kernel space. The sliding window buffer size will be at least large enough to stream the slowest connection speed and can be, e.g., multiple times as large as necessary, in case of the issues beyond the worst-case scenario. The system then transmits chunks of the content from the shared sliding window buffer to each of the plurality of client devices.

    Abstract: Systems and methods are provided for automatically recommending content. One example method includes receiving, from a computing device, a request for content and generating an initial result set in response to the request. A user profile associated with the request is identified.
    Based on the initial result set and the user profile, a positivity index score for the initial result set is determined. Based on the positivity index score, a type of additional content to add to the initial result set is determined. A modified result set is generated by adding the additional content to the initial result set. At least a portion of the modified result set is transmitted to the computing device.

    Abstract: To filter unwanted sounds from a conference call, a voice profile of a first user is generated based on a first voice signal captured by a media device during a first conference call. The voice profile may be generated by identifying a base frequency of the first voice signal and determining a plurality of voice characteristics, such as pitch, intonation, accent, loudness, and speech rate. These data may be stored in association with the first user. During a second conference call, a second voice signal captured by the media device is analyzed to determine, based on the voice profile of the first user, whether the second voice signal includes the voice of a second user. If so, the second voice signal is prevented from being transmitted into the conference call. A voice profile of the second user may be generated from the second voice signal for future use.
