1 Functions
The Audio-Visual Scene Creation (PAF-AVC) AIM receives the Descriptors of a Visual Scene that includes Avatars, the Speech Objects uttered by the Avatars and the Spatial Attitudes of the Avatars, and provides the Descriptors of an Audio-Visual Scene where the Speech Objects associated with each Avatars are attached to the Mouth of each Avatar using the Mouths’ Spatial Attitudes:
| Receives | Visual Scene Descriptors | Descriptors of a Visual Scene. |
| Avatars | Avatars in the Visual Scene. | |
| Mouth Spatial Attitude | Spatial Attitudes of the Avatars in the Scene. | |
| Speech Objects | Speech Objects uttered by the Avatars | |
| Produces | Audio-Visual Scene Descriptors | New AV Scene Descriptors where Speech Objects are located at Avatars’ mouths. |

8 Conformance Testing
Table 2 provides the Conformance Testing Method for the PAF-AVC AIM as a Basic AIM.
Note that a schema may contain references to other schemas. In this case, validation of data for the primary schema implies that any data that refers to a secondary schema shall also validate.
Table 2 – Conformance Testing Method for PAF-AVC AIM
| Receives | Visual Scene Descriptors | Shall validate against Visual Scene Descriptors Schema. |
| Mouth Spatial Attitudes | Shall validate against Spatial Attitude Schema. | |
| Avatars | Shall validate against Avatar Schema. Avatar Model Data shall conform with 3D Model Qualifier. |
|
| Speech Objects | Shall validate against Avatar Schema. Speech Data shall conform with Speech Qualifier. |
|
| Produces | Audio-Visual Scene Descriptors | Shall validate against Visual Scene Descriptors Schema. |
