Scene Composition Information Separation for Multimedia Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multimedia communication systems face challenges in efficiently transmitting and receiving scene composition information, particularly in broadcasting environments, where media attribute information is intertwined with spatial-temporal information, leading to repetitive data generation and discontinuity of media when scenes change.
Innovation Solution
A method and device for separating media attribute information and spatial-temporal information into distinct formats, allowing for efficient transmission and reception of scene composition information, enabling independent composition and updating of scene parts, and maintaining media continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If scene composition information is transmitted in integrated format with media attribute information and spatial-temporal information combined, then the information structure is simple, but the system cannot ensure media continuity when scenes change and generates repetitive data
Solution Approach 1:
The patent divides scene composition information into separate components: media attribute information and spatial-temporal information. This segmentation allows each component to be independently managed and transmitted, ensuring that media continuity is maintained when scenes change while avoiding repetitive data generation. The separated structure enables the receiving device to efficiently process only the changed portions rather than reprocessing entire integrated information blocks.
2Ease of operation
If scene composition information is transmitted in integrated format, then transmission is straightforward, but media attribute information is repetitively generated even for substantially identical media data
Solution Approach 1:
The patent extracts media attribute information from the integrated scene composition information and separates it from spatial-temporal information. This extraction allows the system to transmit only the essential media attributes once, and then reference them across multiple scenes without repetitive generation, thereby reducing data redundancy while maintaining ease of transmission through standardized reference mechanisms.
Solution Approach 2:
The patent creates a universal media attribute information structure that can be referenced across multiple scenes and media elements. This universal format allows substantially identical media data to be described once and reused through references, eliminating repetitive data generation while maintaining the straightforward transmission process through standardized protocols.
3Adaptability or versatility
If a new XML file is created for each scene change, then scene composition is flexible, but media data continuity cannot be ensured between scenes
Solution Approach 1:
The patent establishes preliminary connections between media attribute information and spatial-temporal information that span across scene boundaries. By pre-defining these relationships and using persistent identifiers for media assets, the system maintains media data continuity between scenes while still allowing flexible scene composition through the adaptable XML structure. This preliminary action ensures that when scenes transition, the media data flow remains uninterrupted.
