Abstract: Aspects of the subject disclosure may include, for example, obtaining data indicative, for a frame of a video, of a field of view of a user; determining from a set of homogeneous tiles of the frame a subset of the homogeneous tiles that covers the field of view, wherein the set of homogeneous tiles has been constructed prior to the obtaining of the data; and merging at least a first tile of the set of homogeneous tiles and a second tile of the set of homogenous tiles into a larger tile, wherein the merging is based upon at least one parameter. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, for example, identifying a field of view (FoV) within a first frame of a video that occupies a sub-portion of the frame. A size is determined by subdividing a portion of the video according to a tiling scenario. Tiles overlapping the FoV are detected, and an updated size is determined based on an encoded version of the tiles and compared to a reference size. Responsive to the updated size being less than the reference size, the reference size is adjusted to the updated size, the tiling scenario is adjusted according to an adjusted tiling scenario, and the determining of the size is repeated based on the adjusted tiling scenario. Responsive to the updated size not being less than the reference size, a preferred tiling scenario is identified based on the adjusted tiling scenario for tiling the video. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, for example, a process that analyzes image content of an immersive video frame and identifies a first group of segments of the immersive video frame based on the analysis. The segments collectively span an entire space portrayed by the immersive video frame and the first group of segments spans less than the entire space. A size of a display region of an immersive video viewer is determined that spans less than the entire space and a second group of segments is determined based on the first group of segments and the size of the display region. Transport of the second group of segments, spanning less than the entire space, is facilitated via a communication network to the immersive video viewer for presentation, without requiring transmission of all of the segments. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, for example, identifying FOV and OOS tiles of the video content. The FOV and OOS tiles are received from a video server. The FOV and OOS tiles are encoded using AVC and a first layer of SVC, respectively. Further embodiments include providing the FOV and OOS tiles for presentation on a display, detecting a change in a field of vision, and identifying other FOV tiles of the video content, which comprise a portion of the OOS tiles. Also, embodiments include requesting the portion of the OOS tiles and receiving the portion of the OOS tiles from the video server over the communication network, which are encoded using an enhancement layer of SVC and then provided, to the display, according the enhancement layer in conjunction with the providing of the OOS tiles according to the first layer. Other embodiments are disclosed.
