Abstract
Systems, methods, and devices for spatial adaptation with dynamic adaptive streaming are disclosed. In an embodiment, systems, methods and devices are disclosed for signaling a spatial relationship of one or more tiles in a tiled presentation with an attribute in a media presentation description. In other embodiments, systems, methods and devices are disclosed for server-managed adaptive streaming wherein a client generates and transmits a spatial adaptation URL query parameter to the server for free-zooming or free view-angle spatial adaptation to a region of interest.
Claims15
In a dynamic adaptive streaming system, a method of signaling a spatial relationship of one or more spatial objects in a media presentation description, the method comprising:
- specifying spatial division and layout information of spatial objects;
- and,
- specifying location and spatial relationship information of the spatial objects, wherein streaming adaptation in the spatial domain is from one spatial object to another spatially related spatial object.
A server-managed adaptive streaming system, comprising:
- a client operable to generate and transmit a set of URL query parameters for spatial adaptation to a region of interest;
- and
- a server operable to transmit one or more segments to the client responsive to the set of spatial adaptation URL query parameters, the one or more segments corresponding to the region of interest indicated by the URL query parameters for spatial adaptation.
A method of server-managed adaptive streaming, the method comprising:
- generating, by a client, a set of URL query parameters for spatial adaptation to a region of interest;
- transmitting the generated set of URL query parameters to a server;
- and
- transmitting, from the server, a segment to the client in response to the received set of URL query parameters, the segment corresponding to the URL query parameters.
