AI Technical Summary
Technical Problem
Existing avatar representation formats like ARF lack flexibility in signaling different properties of avatar components, requiring redundant definitions or external references, which hinders efficient encoding and decoding processes.
Method used
Introduce new data types within the ARF data property, specifically using a type property with mime types to define additional properties of avatar components like meshes, blendshapes, and textures, allowing for internal referencing and flexible signaling.
Benefits of technology
Enhances encoding efficiency by allowing internal referencing of avatar component properties, improving flexibility and reducing redundancy in signaling, thereby optimizing the encoding and decoding processes.

Abstract
Methods and apparatus are provided for adding new data types to the Avatar Representation Format data property. The type property is a string providing the mime types of the data. At least one embodiment refers to different signaling ways for the geometry objects using one or more data types. The embodiments define one single signaling way of the Mesh object and add the geometry properties as a Data property. The embodiments then switch between the different signaling ways of the geometry objects by changing the value of type in mesh data. In this case the definition of the Geometry containers is external to the ARF description.
