The decision may be based on a policy which may include a weighted score based on a combination of usage and network efficiency scores. In other aspects, methods and systems are provided to initially provide to a user device a stored version of a content item, and then switch, as needed, to a different version of the content item using on-demand transcoding.

Systems, apparatuses, and methods are described for providing audio assistance during trick play. Users, for example, visually-impaired users, may enable audio assistance features for trick play operations and customize audio assistance settings. The audio assistance may comprise outputting one or more audio cues during trick play. The audio cues may be associated with one or more types of scenes may indicate the progress of a trick play content item. The audio cues may also indicate automatic skipping of an objectionable scene or commercial and the output of a next scene.
H04N 21/454 - Content filtering, e.g. blocking advertisements
H04N 21/439 - Processing of audio elementary streams
H04N 21/44 - Processing of video elementary streams, e.g. splicing a video clip retrieved from local storage with an incoming video stream or rendering scenes according to encoded video stream scene graphs
H04N 21/6587 - Control parameters, e.g. trick play commands or viewpoint selection
Systems, apparatuses, and methods for detecting the reactions of primary and secondary viewers of content are described. Reactions of a primary or secondary viewer of content may be detected through use of a sensor and machine learning model. Based on the reaction of the primary or secondary viewer satisfying some criteria, outputting of the content may be modified and/or alternative content may be provided. Furthermore, metadata may be generated based on the detection of adverse reactions to intrusions by a viewer of content that is associated with an indication that the outputted content is associated with certain predefined types.
H04N 21/442 - Monitoring of processes or resources, e.g. detecting the failure of a recording device, monitoring the downstream bandwidth, the number of times a movie has been viewed or the storage space available from the internal hard disk
H04N 21/422 - Input-only peripherals, e.g. global positioning system [GPS]
H04N 21/462 - Content or additional data management e.g. creating a master electronic program guide from data received from the Internet and a Head-end or controlling the complexity of a video stream by scaling the resolution or bit-rate based on the client capabilities
H04N 21/466 - Learning process for intelligent management, e.g. learning user preferences for recommending movies
Systems, methods, and apparatuses are described for detecting synchronization errors between audio and video signals. Scene changes may be detected based on anchor frames. Offsets between a scene change in a video signal and a reduced audio level or burst of high audio level in the audio signal may indicate a synchronization error.
H04N 21/43 - Processing of content or additional data, e.g. demultiplexing additional data from a digital video streamElementary client operations, e.g. monitoring of home network or synchronizing decoder's clockClient middleware
A privacy gateway may communicate with user devices located at a plurality of premises. The privacy gateway may receive a data packet, from one of the user devices, indicating destinations, such as other computing devices, located external to the premises. The privacy gateway may decrypt at least a portion of the data packet to determine that at least a portion of data in the packet is associated with the user device. The privacy gateway may remove the data associated with the user device from the data packet and replace the removed data with data associated with the privacy gateway. The privacy gateway may send the data packet with the replaced data to a destination device. The privacy gateway may receive a response to the data packet from the destination device. The privacy gateway may encrypt a portion of the response and send the response to the user device.
H04L 9/32 - Arrangements for secret or secure communicationsNetwork security protocols including means for verifying the identity or authority of a user of the system
H04L 67/02 - Protocols based on web technology, e.g. hypertext transfer protocol [HTTP]

Systems, apparatuses, and methods are described for tracking and monitoring access of Rich Call Data (RCD). An RCD system may append call invites with unique links. The RCD system may determine if a recipient device is configured to access RCD by maintaining records relating to access of the unique links.
A computing device (e.g., a content packager) may receive a request for content (e.g., video, audio, games, applications, data). The computing device may send a second request for the requested content to an encoder. In response to the second request, the computing device (e.g., the content packager) may receive the requested content and a content manifest associated with the requested content. The computing device may determine that encryption key data (e.g., an encryption key and/or key metadata) for the requested content is not in a cache associated with the computing device. The computing device (e.g., the content packager or a cache associated with the content packager) may send a request for the encryption key data associated with the requested content to a cache associated with a second computing device, based on the determination that the encryption key data is not in the cache associated with the computing device.
Systems and methods are described herein for authentication and password security. The system may detect involuntary and voluntary brain signals of a user and measure the characteristics of those signals. The signals may be detected and analyzed using a wearable device comprising a plurality of sensors. The system may authenticate the identity of the user by triggering the user to imagine content or react to presented content. The content may comprise an image or movement, and brain signals of the user may indicate signals that are consistent for the user. The system may authenticate the user based on the brain signals based on data stored for the user or profile for the user. This determination may be performed by a machine learning model trained to classify users based on the brain signal data.
