Summary of S4-260218: Proposed Changes to Example Solution Deliverables

1. Introduction and Context

This contribution from Fraunhofer IIS and Dolby Laboratories proposes modifications to the example solution deliverables list for the DaCAS (Diverse audio Capturing System for UEs) work item. The document builds upon the candidate list of example solution deliverables previously specified in S4aA260009.

Key Rationale

• Development of immersive audio capture example solutions is a main objective of DaCAS according to the WID (SP-241962)
• Example solutions are not mandatory and thus not relevant for interoperability
• Example solutions serve primarily as proof of feasibility rather than normative implementations
• Deliverables should be restricted to what is necessary to ensure plausibility and reproducibility

2. Main Technical Contribution

Proposed Streamlined Deliverables List

The document proposes that example solution deliverables should include the following components:

1. List of target device(s) supported

2. High-level description of data used to develop the example solution

3. List of supported output format(s)

4. High-level algorithmic description

5. Executable or library with API (Windows or Linux), including:

6. Guide on how to compile (if applicable)

7. Guide on how to run

8. Report of evaluation results, following at minimum:

9. Test methodologies specified in DaCAS-2 and DaCAS-3

10. Evaluation scenarios specified in DaCAS-2 and DaCAS-3

11. Legal framework (if any) necessary by the solution provider to share the content (e.g., user license for the example solution)

12. Supplementary information

Key Simplifications

The proposed changes appear to emphasize:
- High-level descriptions rather than detailed technical documentation
- Focus on algorithmic description and dataset description at a conceptual level
- Practical implementation artifacts (executable/library) with usage guidance
- Evaluation results aligned with DaCAS test methodologies

3. Conclusion and Next Steps

The document proposes that these modified example solution deliverables be included in the DaCAS-3 permanent document.

The streamlined approach aims to balance the need for proof of concept demonstration with practical considerations around what is necessary for validation and reproducibility of immersive audio capture capabilities.
