Selective streaming of immersive video based on field-of-view prediction

The method of claim 21, further comprising:

• determining, by the processing system, an updated position of the immersive video viewer at an update time after the sample time;
• comparing, by the processing system, the updated position of the immersive video viewer at the update time to the predicted orientation of the immersive video viewer at the presentation time to obtain a comparison result;
• and
• determining an error based on the comparison result.

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

• identifying an immersive video viewer comprising a field-of-view;
• determining a present orientation of the immersive video viewer at a first time;
• predicting a future orientation of the immersive video viewer occurring at a second time using a predictive algorithm, to obtain a predicted orientation of the immersive video viewer based on the present orientation of the immersive video viewer, wherein the predictive algorithm uses one of an average, a linear regression, or a weighted linear regression of a plurality of actual orientations of the immersive video viewer;
• identifying based on the predicted orientation of the immersive video viewer and the field-of-view, a first spatial region of an immersive video frame corresponding to the second time, wherein the immersive video frame comprises the first spatial region and a second spatial region;
• and
• facilitating wireless transmission of the first spatial region of the immersive video frame to the immersive video viewer for presentation at the immersive video viewer at the second time, without requiring transmission of the second spatial region.

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:
• identifying a video viewer comprising a field-of-view;
• determining a present orientation of a display region presented at a first time on a display of the video viewer;
• determining a plurality of actual orientations of the video viewer occurring at a plurality of times preceding the first time;
• predicting a future orientation of the display region occurring at a second time using a predictive algorithm, to obtain a predicted orientation of the display region to be presented at the second time on the display of the video viewer, wherein the predictive algorithm uses one of an average, a linear regression, or a weighted linear regression of the plurality of actual orientations of the video viewer;
• identifying based on the predicted orientation of the display region and the field-of-view, a first spatial region of an video frame corresponding to the second time, wherein the video frame comprises the first spatial region and a second spatial region;
• and
• facilitating wireless transmission of the first spatial region of the video frame to the video viewer for presentation at the video viewer at the second time, without requiring transmission of the second spatial region.
