Multi-Bit Multimedia Streams for Variable Bandwidth and Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multimedia data processing systems waste CPU resources and degrade signal quality due to redundant compression and decompression procedures caused by unpredictable storage space and bandwidth limitations, leading to distorted data.
Innovation Solution
A system and method that utilize an ASIC or DSP to convert primitive multimedia signals into multiple digital data streams with varying compression ratios or types, allowing for direct selection of suitable streams based on storage space and bandwidth limitations, thereby eliminating redundant processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the processed digital signal is decompressed and compressed again according to required compression ratio, then the data can be adapted to storage space or bandwidth limitations, but CPU resources are wasted and system performance degrades
Solution Approach 1:
The patent applies preliminary action by pre-compressing the digital signal into multiple data streams with different compression ratios before transmission or storage. This allows the receiving end to directly select the appropriate stream without needing to decompress and recompress, thereby eliminating redundant processing steps and improving system performance while maintaining adaptability to different storage and bandwidth conditions.
2Adaptability or versatility
If the processed digital signal is decompressed and compressed again, then the compression ratio can be adjusted for different storage or transmission requirements, but the quality of the signal deteriorates and multimedia data becomes distorted
Solution Approach 1:
The patent applies segmentation by dividing the single compressed signal into multiple parallel data streams, each with a different compression ratio. This segmentation allows the receiving end to select the most appropriate stream for the given conditions without needing to reprocess other streams, thereby maintaining signal quality while providing flexibility in compression ratio selection.
3Adaptability or versatility
If a compressor decompresses and recompresses the digital data stream, then the data can be optimized for specific storage or transmission paths, but the processing procedure becomes complicated and redundant
Solution Approach 1:
The patent applies preliminary action by performing all necessary compression variations in advance at the source end, creating multiple ready-to-use data streams. This eliminates the need for complex decompress-recompress operations at intermediate points, simplifying the processing procedure while maintaining the ability to optimize for specific storage or transmission paths.
Data Source
AI summary
A system for processing multimedia data outputs multiple digital data streams of different compressed ratios or types to adapt to multiple limitations of storage spaces and transmission bandwidths, and thus reduce the repetition for processing the digital data streams to save the central processing unit (CPU) resources.
