1 Functions
The Basic Visual Scene Description (OSD-BVD) receives Visual Objects with their Space-Time information and produces the Descriptors of a Scene composed of Visual Objects and optionally an Alert:
| Receives | Space-Time | of the input Objects having the same time base. |
| Visual Objects | Individual Objects. | |
| Produces | Basic Visual Scene Descriptors | Scene Descriptors produced by AIM. |
| Alert | Data concerning potential anomalies in input Object. |

8 Conformance Testing
Table 2 provides the Conformance Testing Method for OSD-BVD 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 OSD-BVD AIM
| Receives | Space-Time | Shall validate against Space-Time schema. |
| Visual Objects | Shall validate against Object schema. Media-specific Data shall conform with their Qualifiers. |
|
| Produces | Basic Visual Scene Descriptors | Shall validate against Scene Descriptors schema. |
| Alert | Shall validate against Alert schema. |
