1 Functions

The Audio-Visual Scene Rendering (PAF-AVR) AIM

  1. Receives an input Point of View and all or some of the following input data: an input Portable Avatar, input Audio-Visual Scene Descriptors, and an input Spatial Attitude.
  2. Produces the Audio, Speech, and Visual components resulting from the rendering from the input Point of View of one of:
    1. The input Audio-Visual Scene Descriptors – if no input Portable Avatar is present.
    2. A speaking avatar constructed according to the data of the input Portable Avatar embedded in the input Potable Avatar’s Audio-Visual Scene Descriptors with the input Spatial Attitude  – if the input Audio-Visual Scene Descriptors are not present.
    3. The input Audio-Visual Scene Descriptors that include an avatar constructed according to the data of the input Portable Avatar and embedded in the input Audio-Visual Scene Descriptors with the input Spatial Attitude – if both input Portable Avatar and input Audio-Visual Scene Descriptors are present.
Receives Portable Avatar Jointly with or alternatively with AV Scene Descriptors.
Audio-Visual Scene Descriptors Alternative to or superseding that of the Portable Avatar.
Spatial Attitude Spatial Attitude of the Avatar in the Audio-Visual Scene.
Point of View To be used in rendering the scene and its objects.
Transforms Portable Avatar Into generic Audio-Visual Scene Descriptors if input Portable Avatar is present.
Produces Portable Avatar’s Output Speech Always integrated in the Audio-Visual Scene. Output Speech results from the rendering of Audio Scene Descriptors from human-selected Point of View.
Output Audio Resulting from the rendering of Audio Scene Descriptors from human-selected Point of View.
Output Visual Resulting from the rendering of Audio Scene Descriptors from human-selected Point of View. View Selector tells the OSD-AVR AIM where the visual components of the Portable Avatar should also be integrated.

8 Conformance Testing

Table 2 provides the Conformance Testing Method for PAF-AVR AIM.

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.

Table 2 – Conformance Testing Method for PAF-AVR AIM

Receives Portable Avatar Shall validate against Point of View Schema.
AV Scene Descriptors Shall validate against AV Scene Descriptors Schema.
Point of View Shall validate against Portable Avatar Schema.
Portable Avatar Data shall conform with respective Qualifiers.
Spatial Attitude Shall validate against Spatial Attitude Schema.
Produces Output Speech Object Shall validate against Speech Object Schema.
Speech Data shall conform with Speech Qualifier.
Output Audio Object Shall validate against Audio Object Schema.
Audio Data shall conform with Audio Qualifier.
Output Visual Object Shall validate against Visual Object or 3D Model Schema.
Visual Data shall conform with Visual Object.
