1 Functions
The Response and Scene Rendering (PAF-RSR) AIM produces the Avatar in an Audio-Visual Scene from AV Scene Descriptors, Point of View of the viewer, Speech or Text and Personal Status:
| Receives | Point of View | Selected by viewer to see/hear the scene. |
| AV Scene Descriptors | Describing the Audio-Visual Scene. | |
| Avatar PoV | The Point of View of the Avatar in the AV Scene. | |
| Input Speech | Speech alternative to Speech synthesised from Text Object. | |
| Speech Model | The Speech Model used to synthesise Speech. | |
| Text Object | To be used to: 1. Synthesise into Speech using a provided or an internal Speech Model 2. Generate Face Descriptors and Body Descriptors. |
|
| Personal Status | To be used as additional information to synthesise Speech and generate Face and Body Descriptors. | |
| Avatar Model | When a specific Avatar Model is externally provided. | |
| Produces | Output Speech | The output Speech Object . |
| Audio Speech | The Audio of the Audio-Visual Scene Descriptors. | |
| Output Visual | The rendering of the animated avatar and the visual scene. |

8 Conformance Testing
Table 2 provides the Conformance Testing Method for PAF-PSRAIM.
If a schema contains references to other schemas, conformance of data for the primary schema implies that any data referencing a secondary schema shall also validate against the relevant schema, if present and conform with the Qualifier, if present.
