Patent Images

1. A method comprising:

  • receiving, by a computing device, spherical content for video;

    generating, by the computing device, a plurality of face images from the spherical content to represent an image in the video;

    generating, by the computing device, a two dimensional sheet for the plurality of face images, wherein one or more face images are positioned next to each other based on the one or more face images associated position on an object structure;

    reducing, by the computing device, a size of the plurality of face images;

    adding, by the computing device, a pixel frame around each of the plurality of face images on the sheet, the pixel frame including pixels from a neighboring face image on the object structure;

    adding, by the computing device, a plurality of gaps on the sheet next to edges of the plurality of face images;

    adding, by the computing device, gap content in the plurality of gaps, wherein the gap content is based on content in an area proximate to the plurality of gaps;

    encoding, by the computing device, the plurality of face images, the pixel frame, and the gap content on the sheet; and

    sending, by the computing device, the encoded sheet to a decoder, wherein the plurality of face images are decoded using the pixel frame and the gap content for placement on the object structure to display the spherical content.
