A system that determines that devices are co-located in an acoustic region and selects a single device to which to send incoming notifications for the acoustic region. The system may group devices into separate acoustic regions based on selection data that selects between similar audio data received from multiple devices. The system may select the best device for each acoustic region based on a frequency that the device was selected previously, input/output capabilities of the device, a proximity to a user, or the like. The system may send a notification to a single device in each of the acoustic regions so that a user receives a single notification instead of multiple unsynchronized notifications. The system may also determine that acoustic regions are associated with different locations and select acoustic regions to which to send a notification based on location.

Disclosed are various embodiments for predictive caching of content to facilitate instantaneous use of the content. If a user is likely to commence use of a content item through a client, and if the client has available resources to facilitate instantaneous use, the client is configured to predictively cache the content item before the user commences use. In doing so, the client may obtain metadata for the content item from a server. The client may then initialize various resources to facilitate instantaneous use of the content item by the client based at least in part on the metadata.

Predictive caching for content

Disclosed are various embodiments for predictive caching of content to facilitate use of the content. If account is likely to commence use of a content item, the content item is cached before the use is commenced. The cache may be divided into multiple segments with different content selection criteria.

Segmented predictive caching for content

Techniques are described for balancing traffic among content delivery networks (CDNs). A CDN balancer can analyze CDN performance data and determine CDN balancing ratios used to distribute traffic among the CDNs.

Systems, methods, and computer-readable media are disclosed for systems and methods for dynamic mode switching and management of communications between devices. Example methods include receiving a first event from a first application on a first device, determining a first application identifier of the first application, and determining that the first device is in a communal mode. Example methods may include determining a communal mode profile for the first device, where the communal mode profile is associated with a first user account identifier that is associated with the first device, determining a set of user account identifiers associated with an accessory device identifier of the accessory device, and associating the set of user account identifiers and the accessory device identifier with the communal mode profile. Example methods may include receiving an indication of a second event, and disassociating the set of user account identifiers from the communal mode profile.

Communications for multi-mode device

Disclosed are various embodiments for client-side predictive caching of content to facilitate use of the content. If account is likely to commence use of a content item through a client, the client is configured to predictively cache the content item before the use is commenced. In doing so, the client may obtain an initial portion of the content item from another computing device. The client may then initialize various resources to facilitate use of the content item by the client. The client-side cache may be divided into multiple segments with different content selection criteria.

Client-side predictive caching for content

Techniques are described for live streaming media content using on-demand manifests. Many manifest files providing playback options for different time periods of a live stream of media content can be generated and provided to viewer devices. Requests from viewer devices using the manifest files can be analyzed to determine a fragment to be provided for playback in relation to the time period of the live stream to be provided for playback.

Live streaming media content using on-demand manifests

Techniques are described for live streaming media content using on-demand manifests. A manifest file providing playback options for a portion of the duration of the playback of a live stream can be provided to viewer devices. The viewer devices can also be provided location identifiers for the live stream. Based on the location identifier used by the viewer devices to request fragments of the live stream of the media content, the requests from the viewer devices using the manifest file can be analyzed to determine a fragment to be provided for playback in relation to the time period of the live stream.

Embodiments may include the generation and use of content source rankings for improving playback quality of content streams. In embodiments, a merchant system may collect and aggregate multiple quality metrics for different content streams that various content sources provide to various clients. The merchant system may utilize the quality metrics to generate rankings of content sources for clients. In some cases, a client itself may generate a ranking of content sources for use in the selection of content sources. The merchant system may provide such rankings to clients to improve the content stream playback experience on the client. For instance, at content acquisition time, a client may request a content stream from a content resource ranked highest on a content source ranking provided by the merchant. If the content stream degrades, the client may source subsequent portions of the content stream from another highly ranked content source of the ranking.

System and method for selection and switching of content sources for a streaming content session

Disclosed are various embodiments for tracking media consumption by multiple devices. On a computing device, a first media consumption report is received. The first media consumption report is associated with a media title on a first client device. The first client device is registered by a user. A rights windows in a license associated with the media title is reconciled with the first media consumption report. Responsive to the reconciling, the reconciled license is propagated to the first client device.
