System and method for adaptive spatial content streaming with multiple levels of detail and degrees of freedom

A method, comprising:

• receiving at a client device, a manifest file identifying a plurality of content representations available for streaming, the available content representations comprising representations designed for user navigation using multiple different degrees of freedom (DoF);
• selecting at the client device, a first representation designed for user navigation using a first DoF;
• sending a request for the first representation to a content server;
• receiving the first representation as streaming content from the content server;
• rendering the first representation using the first DoF;
• selecting at the client device, a second representation designed for user navigation using a second DoF, the second DoF being different from the first DoF;
• sending a request for the second representation to the content server;
• receiving the second representation as streaming content from the content server;
• and
• switching from rendering the first representation of the content using the first DoF to rendering the second representation of the content using the second DoF.

A device, comprising:

• a processor, and
• a memory, the memory storing instructions that, when executed by the processor, cause the device to:
• receive a manifest file identifying a plurality of content representations available for streaming, the available content representations comprising representations designed for user navigation using multiple different degrees of freedom (DoF);
• select a first representation designed for user navigation using a first DoF;
• send a request for the first representation to a content server;
• receive the first representation as streaming content from the content server;
• render the first representation using the first DoF;
• select a second representation designed for user navigation using a second DoF, the second DoF being different from the first DoF;
• send a request for the second representation to the content server;
• receive the second representation as streaming content from the content server;
• and
• switch from rendering the first representation of the content using the first DoF to rendering the second representation of the content using the second DoF.

A method, comprising:

• receiving at a client device, a manifest file identifying a plurality of content representations available for streaming, the available content representations comprising representations designed for user navigation using multiple different degrees of freedom (DoF) and having multiple different levels of detail (LoD), the manifest file identifying a DoF and an LoD for each of the plurality of available content representations;
• selecting at the client device, a first representation of the plurality of available content representations, the selection of the first representation based on the DoF identified in the manifest file for the first representation, the LoD identified in the manifest file for the first representation, and an estimate of available network bandwidth,
• wherein the first representation is designed for user navigation using a first DoF;
• sending a request for the first representation to a content server;
• receiving the first representation as streaming content from the content server;
• and
• rendering the first representation on the client device using the first DoF.
