摘要： An exemplary system generates a plurality of different content files each including data representative of content of a virtual reality world, and provides the plurality of different content files to a media player device via a network. In particular, the generated and provided plurality of different content files comprises at least one of a plurality of uniform-resolution content files and a plurality of mixed-resolution content files. The plurality of uniform-resolution content files are each associated with a different respective center point within the virtual reality world. The plurality of mixed-resolution content files each correspond to one respective content sector of a plurality of partially overlapping content sectors that together form a view of the virtual reality world associated with a single center point, the one respective content sector being encoded in a high resolution while a remainder of the content sectors are encoded in a low resolution.

摘要： An exemplary interactive media content provider system generates overall data representative of interactive media content. The exemplary interactive media content provider system concurrently provides the overall data to both a first media player device associated with a first user and a second media player device associated with a second user by way of a point-to-multipoint media delivery protocol. The first media player device and the second media player device may each be configured to render different portions of the overall data to respective display screens of the media player devices at a particular point in time based on different user input from the first user and the second user, respectively, as the first user and the second user independently interact with the interactive media content. Corresponding methods and systems are also described.

摘要： The quality of a multicast broadcast that is being received by a mobile device may be determined. In one implementation, a method may include receiving a radio signal corresponding to a multicast broadcast of content; measuring a strength of the received signal; determining a minimum signal strength to receive the content associated with the multicast broadcast; determining a signal quality metric, associated with the multicast broadcast, the signal quality metric being based on a difference between the measured strength of the signal and the determined minimum signal strength; and providing a visual indication of the signal quality metric.

摘要： A service quality metric, that measures the quality of a multicast broadcast that is being received by a mobile device, may be determined. In one implementation, a method may include receiving a radio signal corresponding to a multicast broadcast of content that was encoded using a forward error correction (FEC) technique in which the content is segmented and encoded as a plurality of blocks; and reassembling the content corresponding to the received radio signal. The method may further include determining an FEC failure rate based on a relative occurrence of the successfully reassembled blocks to the unsuccessfully reassembled blocks; determining a service quality metric based on the FEC failure rate; and providing a visual indication of the service quality metric.
