Systems, apparatuses, and methods are described for relocalizing a mobile device within an extended reality environment. A subset of a data set, such as a feature pointcloud may be generated based on determining an approximate location of a mobile device. The approximate location may be determined based on data received from one or more sensors in the extended reality environment. Features associated with the approximate location may be included in the subset while other features may be removed. Features extracted from an image taken by the mobile device may be compared with the subset of the data set to relocalize the mobile device.

Extended reality localization

Systems, methods, and devices for providing guided collaborative viewing are described herein. In example implementations, a user navigates navigable image content such as immersive content, 360° video, and the like. During the navigation, navigation data is generated that indicates the orientations of the user's view of the navigable image content. Various techniques are employed to obtain variant navigation data from the navigation data generated during the user's navigation. The techniques used to obtain the variant navigation data include techniques to stabilize the orientations of the user's view and smooth transitions between orientations of the user's view. The variant navigation data is provided to another user in order to enable the other user to follow the navigation of the navigable image content. By using the variant navigation data rather than the original navigation data, following the user's navigation may be more comfortable and less disorienting for the other user.

Guided collaborative viewing of navigable image content

The disclosure relates to a method of delivering a video frame. One implementation may involve spatially partitioning a video frame into a plurality of blocks, encoding at least one of the plurality of blocks of the video frame, and transmitting the at least one of the plurality of blocks of the video frame.

Video delivery

Methods and systems for providing content are disclosed. Content may be provided to a first device. A manifest file may be generated. The content may be provided to a second device.

Efficient data distribution to multiple devices

Methods, systems, computer-readable media, and apparatuses for providing policy-based copyright enforcement of media content items streamed to client devices are described. Various aspects discussed herein relate to managing content access rights in an adaptive bitrate environment (e.g., where an asset may be encoded and delivered at multiple different bitrates). The system discussed herein permits differentiated access to the same video, or portions of the same video, where any DRM-type client may read a manifest file including content verification data, which may be video authentication information that is specific to the video. Additional aspects discussed herein provide DRM metadata specific to each frame of a multi-bitrate video to enable the client device to verify the multi-bitrate video on a frame-by-frame basis.

Adaptive rights management system

Provided are methods and systems for ambient system control, comprising multiple detection devices with varying levels of detection capability. The methods and systems contemplate the use of both voice and gesture commands, as well as other inputs, for system control.

Methods and systems for ambient system control

Methods and systems are described for providing conditional access to a service. One or more tasks may be associated with a user profile. The one or more tasks may be indicated as required to be completed to access the service. The one or more tasks may have associated deadlines. If a task is not completed by the deadline, then any device associated with the user profile may be blocked from access to the service.

Access control using task manager

Systems, apparatuses, and methods are described for identifying and managing event notifications. An event notification manager may determine whether the received data corresponds to an occurring or a false event. The event notification manager may cause one or more user devices to output an event notification by at least partially interrupting output of other content.

Managing event notifications

An enhanced viewing device may move with a user as the user moves around the room. An amount of movement associated with the enhanced viewing device may be determined. Based on the amount of movement, an enhanced viewing experience may be determined and displayed to the user.

Determination of enhanced viewing experiences based on viewer engagement

A viewer may zoom in on an image to see a portion of the image. The image may be analyzed to determine if zoom enhancement is necessary. The zoomed region may be matched to a replacement texture. The replacement texture may be used to enhance the image by replacing some or all of the image data.

Method to generate additional level of detail when zooming in on an image

Systems, methods, and apparatuses are described for verification of wireless network connection. A wireless local area network may comprise a client device and a gateway. A data connection, within the wireless local area network, between the client device and the gateway may be verified based on gateway identifiers provided to the client device via data communication channels internal and external the wireless local area network.

Verification of wireless network connection

Systems and methods are described to enable the creation and use of one or more interest meshes that may comprise interest values associated with points of interest in a virtual environment. A mesh may adapt to different environments and may be automatically created based on predefined criteria used to assign interest values to digital assets or points (e.g., coordinates) in the virtual environment. The virtual environment may use a mesh to guide a user toward points of interest by determining desired positions and viewpoint orientations for the user and guiding the user from point to point. Further, events may be triggered in the virtual environment that may change one or more meshes and/or create a new point of interest for a user. The user may then be guided using the changed mesh(es) to points of interest, including new points of interest.

Overlay placement for virtual reality and augmented reality

Methods and systems are disclosed relating to proximity detection of devices and targeted information services, such as information campaigns. Disclosed methods provide targeted campaigns to a user, such as targeted campaigns to presentation devices based on proximity of user devices near the information devices. Other methods provide targeted campaigns across various applications, while other methods provide for scheduling campaigns to premises device identifiers based on an event schedule, and other methods provide a hierarchal system for monitoring different sets of premises device identifiers when a user device can monitor for a limited number of premises device identifiers at a time.

Systems and methods for low energy beacon management

Methods, systems, and apparatuses are described for context-based speech processing. A current context may be determined. A subset of trigger words or phrases may be selected, from a plurality of trigger words, as trigger words that a computing device is configured to recognize in the determined current context. The computing device may be controlled to listen for only the subset of trigger words during speech recognition.

Voice command trigger words

A wireless signal may supply a wireless power signal to a device to power the device for an authentication. If the device is authenticated, the wireless signal may be adjusted to provide power to the device. If the device is not authenticated, the wireless signal may be adjusted to avoid providing power to the device.
