1. A method of managing media storage and delivery, the method being implemented by at least one processor and comprising:
obtaining, by a media access function (MAF), a Graphics Language Transmission Forma (glTF) file corresponding to a scene;
obtaining from the glTF file a uniform resource locator (URL) parameter indicating a binary data blob;
determining that the binary data blob has a Concise Binary Object Representation (CBOR) format;
converting the binary data blob into an object having a JavaScript Object Notation (JSON) format using a CBOR parser function implemented by the MAF; and
obtaining media content corresponding to the scene based on the object,
wherein the binary data blob is determined to have the CBOR format based on a prefix included at a beginning of the binary data blob.
