Redundant cache for reusable immersive media assets

A non-transitory computer-readable medium storing instructions that, when executed by at least one processor of a device for streaming media assets during a media streaming session using a redundant cache managed by a media streaming server in a media streaming network, cause the at least one processor to:

• receive, by a media streaming server, immersive media stream comprising one or more immersive media assets associated with one or more scenes;
• determine that a subset of the one or more immersive media assets are included for a plurality of times in the one or more scenes;
• store a redundant copy of each of the subset of the one or more immersive media assets in a cache maintained by the media streaming network to ensure that the each of the subset is accessible to both the media streaming server and a client;
• and
• stream at least one media asset of the subset of the one or more immersive media assets in response to a local cache of the client not storing the at least one media asset.

An apparatus for streaming media assets during a media streaming session using a redundant cache managed by a media streaming server in a media streaming network, the apparatus comprising:

• at least one memory configured to store computer program code;
• and
• at least one processor configured to read the computer program code and operate as instructed by the computer program code, the computer program code comprising:
• receiving code configured to cause the at least one processor to receive, by a media streaming server, immersive media stream comprising one or more immersive media assets associated with one or more scenes;
• first determining code configured to cause the at least one processor to determine that a subset of the one or more immersive media assets are included for a plurality of times in the one or more scenes;
• first storing code configured to cause the at least one processor to store a redundant copy of each of the subset of the one or more immersive media assets in a cache maintained by the media streaming network to ensure that the each of the subset is accessible to both the media streaming server and a client;
• and
• streaming code configured to cause the at least one processor to stream at least one media asset of the subset of the one or more immersive media assets in response to a local cache of the client not storing the at least one media asset.

The non-transitory computer-readable medium of claim 17, wherein the instructions further cause the at least one processor to:

• determine whether a media asset has been streamed to a client device;
• based on determining that the media asset has been streamed to the client device, determine whether a copy of the media asset is stored on a local cache managed by the client device;
• based on determining that the copy of the media asset is not stored on the local cache managed by the client device, generate a first substitute proxy for the media asset, wherein the first substitute proxy indicates that the client device use the copy of the media asset stored in the redundant cache managed by the media streaming network;
• and
• stream immersive media comprising the first substitute proxy of the media asset instead of the media asset.

The non-transitory computer-readable medium of claim 17, wherein the instructions further cause the at least one processor to:

• based on determining that the media asset has not been streamed to the client device, determine one or more format conversions to be performed on the media asset;
• perform the one or more format conversions on the media asset;
• stream immersive media comprising the converted media asset;
• and
• based on determining that the converted media asset is to be reused in the media streaming session, generate the copy of the media asset to be stored on the redundant cache managed by the media streaming network.
