Methods, systems, and apparatuses are disclosed for server selected bitrate streaming. A server receives a request from a user device for data segments at a first bitrate. The server determines a second bitrate for transmission of the data segments to the user device. The server transmits the requested data segments at the determined second bitrate.

Server selected variable bitrate streaming

Systems, apparatuses, and methods are described for monitoring data transmitted and/or received via multicast transmission and, based on latency, segment loss, and/or other occurrence, modifying sources and/or other characteristics of additional data transmission. The data may be video segments of media content items. Sources of video segments can be changed based on comparisons of rates of arrival of video segments, failure to receive segments, etc. Selection of an encoded version of content for multicast and/or unicast transmission may be based on indications of delay and/or non-receipt, and/or based on predictions of increased load on a network.

Adaptive multicast streaming

Systems, apparatuses, and methods are described for providing updated manifests for content items. The updated manifests may present one or more expected characteristics for a given one or more segments of the content items. The device receiving the content item may use the updated manifests to select a representation of the content item or portion thereof.

Dynamic content delivery

The disclosure relates generally to providing content from a source to a user device. In one implementation, a source such as a server receives a request for a master manifest file. The server may identify one or more other manifest files and at least one data block associated with the content. The other manifest files can include manifest files referenced by the master manifest file, or can include manifest files associated with related content. The requested master manifest, the one or more other manifest files, and the at least one data block can be pushed to the user device.
