Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple alternative bitstreams are provided for immersive media, then adaptability and versatility are improved, but device complexity increases due to lack of clear relationship indications
Solution Approach 1:
The patent introduces relationship indication information as an intermediary element that mediates between multiple alternative bitstreams and the decoding device. This information explicitly describes the alternative relationships, allowing the decoder to understand how different bitstreams relate to each other without requiring complex analysis or heuristics, thus resolving the contradiction between adaptability and complexity
Solution Approach 2:
The patent segments the overall bitstream structure into distinct alternative bitstreams with clear demarcations and relationship indications. By dividing the immersive media content into separately identifiable alternative representations with explicit relationship metadata, the system achieves high adaptability while maintaining manageable complexity through structured organization
2Manufacturing precision
If relationship indication information is added to indicate alternative relationships between bitstreams, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The relationship indication information is prepared and embedded in advance during the bitstream encoding and packaging phase, before the decoding process occurs. This preliminary action ensures that all necessary relationship information is already in place, allowing precise decoding without requiring complex real-time analysis, thus achieving precision while controlling complexity

AI summary
In a method for decoding immersive media data, a media file of immersive media is obtained. The immersive media includes N alternative bitstreams. The media file includes relationship indication information. The relationship indication information indicates an alternative relationship between the N alternative bitstreams. N is an integer greater than 1. The media file is decoded based on the relationship indication information to present the immersive media.
