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.
Claims20
A device comprising:
- a processing system including a processor;
- and
- a memory that stores executable instructions that, when executed by the processing system, perform operations, the operations comprising:
- obtaining data indicative, for a frame of a streaming video, of a field of view of a user;
- determining from a set of homogeneous tiles of the frame of the streaming video a subset of the homogeneous tiles that covers the field of view of the user, each tile of the set of homogeneous tiles having a first area, the set of homogeneous tiles having been constructed for the frame of the streaming video based upon a bandwidth required to transmit some or all tiles of the set of homogeneous tiles at a given quality level, and the set of homogeneous tiles having 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, the larger tile having a second area that is greater than the first area, the merging being based upon at least a first parameter that is indicative of a first estimated network bandwidth required to support the given quality level, and the merging comprising merging only a portion of the first tile with at least the second tile into the larger tile.

A non-transitory computer-readable storage medium comprising executable instructions that, when executed by an end user device including a processor, facilitate performance of operations, the operations comprising:
- sending to a server data indicative, for a frame of a streaming video, a field of view of a user of the end user device, the server facilitating a determining from a set of homogeneous tiles of the frame of the streaming video a subset of the homogeneous tiles that covers the field of view of the user, each tile of the set of homogeneous tiles having a first area, the set of homogeneous tiles having been constructed for the frame of the streaming video based upon a bandwidth required to transmit some or all tiles of the set of homogeneous tiles at a given quality level, the set of homogeneous tiles having been constructed prior to the sending of the data, the server facilitating a merging of 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, the larger tile having a second area that is greater than the first area, the merging being based upon at least a parameter that is indicative of an estimated network bandwidth required to support the given quality level, and the merging comprising merging only a portion of the first tile with at least the second tile into the larger tile;
- receiving, from the server, a set of heterogeneous tiles including the larger tile and one or more tiles from the subset of tiles that do not overlap the larger tile;
- and
- presenting, based upon the set of heterogeneous tiles that is received from the server, an image to the user of the end user device.

A method comprising:
- storing, by a processing system including a processor, a set of homogeneous tiles that has been constructed for a frame of a streaming video based upon a bandwidth required to transmit some or all tiles of the set of homogeneous tiles at a given quality level, each tile of the set of homogeneous tiles having a first area;
- determining, by the processing system, a frequently requested portion of the frame of the streaming video;
- obtaining by the processing system data indicative, for the frame of the streaming video, a current field of view of a user, the frequently requested portion having been determined by the processing system prior to the obtaining of the data indicative of the current field of view of the user;
- determining by the processing system, from the set of homogeneous tiles of the frame of the streaming video, a subset of the homogeneous tiles that covers the current field of view of the user, and the set of homogeneous tiles having been constructed prior to the obtaining the data;
- and
- merging, by the processing system, 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, the larger tile having a second area that is greater than the first area, the merging being based upon at least a first parameter, and the merging comprising merging only a portion of the first tile with at least the second tile into the larger tile.
