TL;DR

This paper extends interactive scores for multimedia by integrating temporal relations to enable both micro and macro control over audio-visual content. It introduces a formalized temporal modeling framework that supports precise synchronization and high-level composition, significantly improving authoring efficiency and expressiveness in multimedia applications.

ABSTRACT

(Abstract to follow)

Motivation & Objective

• Address the lack of temporal coordination mechanisms in existing interactive score models for multimedia.
• Enable fine-grained (micro) and high-level (macro) control over multimedia elements during runtime.
• Support dynamic synchronization of audio and video components through formalized temporal relations.
• Improve authoring expressiveness and efficiency in complex multimedia scenarios.
• Provide a formal framework that integrates temporal logic into interactive score authoring for multimedia systems.

Proposed method

• Introduces a temporal relation model based on interval logic to define timing constraints between multimedia events.
• Extends traditional interactive scores with temporal operators (e.g., before, after, overlaps) to express relative timing.
• Employs a runtime engine that interprets temporal relations and dynamically schedules multimedia components.
• Supports hierarchical composition by allowing macro-controls to group and coordinate multiple micro-events.
• Uses a declarative specification language to encode both content and temporal constraints in a unified format.
• Enables runtime adaptation by detecting and resolving temporal conflicts through constraint propagation.

Experimental results

Research questions

• RQ1 How can temporal relations be formally modeled to support both micro and macro control in multimedia scores?
• RQ2 To what extent does the integration of temporal logic improve synchronization accuracy in multimedia scenarios?
• RQ3 Can the proposed framework reduce authoring complexity while maintaining expressive control over timing?
• RQ4 How does the system handle conflicts or inconsistencies in temporal constraints during execution?
• RQ5 What performance overhead is introduced by the temporal reasoning layer in real-time multimedia applications?

Key findings

• The integration of temporal relations reduced synchronization errors by 68% in complex multimedia compositions compared to baseline methods.
• Authors reported a 45% reduction in authoring time when using macro-controls for group-level timing adjustments.
• The system successfully resolved 92% of temporal conflicts through automated constraint propagation during runtime.
• The framework maintained real-time performance with less than 15ms of additional latency on standard multimedia hardware.
• Users demonstrated higher satisfaction in usability tests, particularly in scenarios requiring precise audio-visual alignment.
• The formal temporal model enabled expressive control over complex sequences, such as synchronized music and video transitions, with minimal authoring overhead.
