Abstract: Systems and methods are disclosed herein for media quality selection of media assets based on internet service provider data usage limits. One disclosed technique herein discusses receiving a data usage limit from an internet service provider. The data usage limit includes maximum data usage for particular user account data. A media asset is selected from a media streaming server that includes a plurality of qualities having respective data sizes (e.g., for video quality—4K, 1080p, etc.) A determination is made whether a selected data size from a selected quality of the plurality of qualities of the selected media asset exceeds remaining data of the received data usage limit. If so, a request is transmitted to the to the media streaming server to retrieve the selected media asset with a quality having a data size smaller than the respective data size.

Abstract: Systems and methods are described herein for transmitting a content item to a user device using multiple delivery protocols. The system receives, at a content source, a request for the content item from the user device. The system splits a digital stream of the content item into a first video signal and a second video signal. The system then transmits, via a unicast server, the first video signal for the content item to the user device, and transmits, via a multicast server, the second video signal for the content item to the user device. The system then causes for presentation on the user device the first video signal followed by the second video signal. In other embodiments, the system is optimized between the unicast delivery of a content item and a peer-to-peer delivery.

Abstract: Systems and methods are described for recommending a proposed hardware configuration to a first user in response to determining that a performance aspect of the first user having a first hardware configuration playing a multiplayer game is worse than a performance aspect of a second user having a second hardware configuration jointly playing the multiplayer game. The proposed hardware configuration is generated based on the first hardware configuration and the second hardware configuration and caused to be displayed on a device of the first user.

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 for curation of content, such as e-learning content or online instructional materials, according to particular criteria such as the amount of pictorial representations contained therein, the amount of verbal expression contained therein, and whether the content contains a summary. Other criteria may also be employed. Users may select any one or more of these and other criteria. Content is then sorted according to the selected criteria and presented as an ordered list of content that users can select for viewing.

Abstract: Systems and methods are described for caching content items. At least first and second content items are stored in a cache. A determination is made as to whether there is common content between the first content item and the second content item. In response to determining that there is common content between the first content item and the second content item, at least a portion of one of the first content item and the second content item is deleted. A request for the common content is received. In response to receiving the request for the common content, the common content is retrieved from the other of the first content item and the second content item.

Abstract: The system and methods described aid content delivery by providing requested content using a hybrid delivery of unicast and multicast content. A content delivery system receives, from user equipment, a request for content and identifies multicast sources for the content. The content delivery system determines a recent multicast source from the multicast sources, the recent multicast source having begun more recently relative to the other sources. The content delivery system transmits, to the user equipment, an identity of the recent multicast source and provides a beginning portion of the content to the user equipment via a unicast stream.

Abstract: To filter unwanted sounds from a conference call, a first voice signal is captured by a first device during a conference call and converted into corresponding text, which is then analyzed to determine that a first portion of the text was spoken by a first user and a second portion of the text was spoken by a second user. If the first user is relevant to the conference call while the second user is not, the first voice signal is prevented from being transmitted into the conference call, the first portion of text is converted into a second voice signal using a voice profile of the first user to synthesize the voice of the first user, and the second voice signal is then transmitted into the conference call. The second portion of text is not converted into a voice signal, as the second user is determined not to be relevant.

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: Systems and methods are disclosed herein for providing a recommendation to modify deficient a deficient content item. A plurality of content items associated with a topic is retrieved. Each of the content items includes a plurality of portions each associated with a respective sub-topic. A rating for each sub-topic of the content items is calculated, and a minimum viable subset of the sub-topics is identified based on the calculated ratings. A new content item associated with the topic is accessed. A plurality of portions of the new content item is identified and a sub-topic for each identified portion is determined. An omitted sub-topic of the minimum viable subset of the sub-topics that is not included in the sub-topics of the new content item is identified, and the system interrupts upload of the new content and recommends modifying the new content item to include a portion with the omitted sub-topic.

Abstract: Systems and methods are described herein for automatically identifying spam in social media comments based on comparison of the context or topic of the popular or trending post with the context or topic of each comment associated with the post. Content of a social media post is processed to identify a topic of the social media post. A plurality of comments associated with the social media post are accessed and the topic of each comment is compared to the topic of the social media post and, if the topics do not match, the comment is identified as spam. A notification is generated for display to an administrator of the social media platform on which the social media post resides identifying the comment as spam.

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.
