Method of audio-assisted field of view prediction for spherical video streaming

A device, comprising:

• a processing system including a processor;
• and
• a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, the operations comprising:
• determining that a first source and a second source in a first sorted list of a plurality of sources of audio have approximately a same amount of energy and different spatial locations;
• determining that a third, dominant source in the first sorted list of the plurality of sources of audio has a location that is nearer to the first source than the second source;
• ordering, based on the determining that the third, dominant source in the first sorted list of the plurality of sources of audio has a location that is nearer to the first source than the second source, the first source higher than the second source in a second sorted list of the plurality of sources of audio, wherein the second sorted list of the plurality of sources of audio is based on the first sorted list of the plurality of sources of audio;
• prefetching, in an order of the second sorted list of the plurality of sources of audio, video data;
• and
• rendering audio data and the video data corresponding to a selected field of view.

A non-transitory, machine-readable medium, comprising executable instructions that, when executed by a processing system including a processor, facilitate performance of operations, the operations comprising:

• determining that a first source and a second source in a first sorted list of a plurality of sources of audio have approximately a same amount of energy and different spatial locations;
• determining that a third, dominant source in the first sorted list of the plurality of sources of audio has a location that is nearer to the first source than the second source;
• ordering, based on the determining that the third, dominant source in the first sorted list of the plurality of sources of audio has a location that is nearer to the first source than the second source, the first source higher than the second source in a second sorted list of the plurality of sources of audio;
• and
• prefetching video data in an order of the second sorted list of the plurality of sources of audio in plural fields of view centered on spatial coordinates of each audio source in the second sorted list of the plurality of sources of audio.
