Multimedia Bitstream Content Embedding for Temporal Compression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for processing and editing multimedia content, such as digital audio or video, are inefficient due to repeated analysis of multimedia bitstreams without consideration of prior processing, leading to time-consuming and resource-intensive reanalysis, especially when the content is converted between formats or modified temporally.
Innovation Solution
An automated system that embeds derived content information into multimedia bitstreams, allowing for the embedding and extraction of metadata for modifying playback duration, enabling efficient temporal compression and reuse of analysis results across different software and users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multimedia bitstream is completely re-analyzed without consideration of prior analysis, then analysis accuracy is maintained, but processing time and computing resources are wasted
Solution Approach 1:
The patent performs content derivation and analysis beforehand, embedding the derived content information directly into the multimedia bitstream during encoding. This preliminary action ensures that when the bitstream is subsequently decoded or processed, the analysis results are already available, eliminating the need for repeated full analysis and thus resolving the contradiction between maintaining analysis accuracy and reducing processing time
Solution Approach 2:
The patent introduces derived content information as an intermediary element that carries pre-analyzed content characteristics within the bitstream. This intermediary allows downstream processes to access analysis results without performing complete reanalysis, thereby maintaining accuracy while significantly reducing processing time and computational resources
2Adaptability or versatility
If multimedia bitstream is passed to another user or analyzed using different software, then content accessibility is improved, but prior analysis information is lost
Solution Approach 1:
The patent merges the derived content information with the original multimedia content by embedding it directly into the bitstream structure. This combination ensures that when the bitstream is transferred to another user or analyzed by different software, the valuable analysis information travels with the content, preventing information loss while maintaining broad accessibility and compatibility
Solution Approach 2:
The patent creates a universal bitstream format that incorporates derived content information in a standardized manner, allowing the same bitstream to be successfully decoded and utilized by different software applications and users. The embedded information serves multiple functions across different platforms, ensuring both accessibility and information preservation
3Adaptability or versatility
If format conversion is performed without considering prior analysis, then format compatibility is achieved, but redundant analysis increases processing complexity
Solution Approach 1:
The patent performs content derivation during the initial encoding phase, embedding the results into the bitstream before format conversion is needed. This preliminary analysis eliminates the need for repeated analysis during format conversion operations, reducing processing complexity while maintaining full format compatibility through proper bitstream restructuring
