Media Stream Reconstruction via Proprietary Header Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Media streams encoded and transmitted using proprietary protocols and file formats become unintelligible to systems lacking knowledge of these specifics, as they modify streams by adding headers, trailers, or removing original components, rendering them incompatible across different devices and networks.
Innovation Solution
A method and system that reconstruct a standard media stream from two modified media streams by normalizing and aligning them to identify and replace proprietary headers and trailers with standard ones, allowing the reconstruction of the original media stream without prior knowledge of the proprietary protocols or formats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If proprietary protocols and file formats are used to encode and transmit media streams, then devices can use their own custom formats and headers, but the media streams become unintelligible to systems lacking knowledge of these proprietary specifics
Solution Approach 1:
The patent introduces a reconstruction system that acts as an intermediary between proprietary media stream formats and standard formats. The system receives modified media streams with proprietary headers, reconstructs the original standard media streams by removing proprietary additions, and outputs compatible standard formats. This mediator approach allows devices using different proprietary formats to communicate through a common standard interface.
Solution Approach 2:
Instead of attempting to make standard systems understand proprietary formats, the patent inverts the approach by having the proprietary-modified streams transformed back into standard formats. The reconstruction system works backwards from the modified stream to recover the original standard media stream, making it intelligible to standard systems without requiring them to understand proprietary protocols.
2Ease of manufacture
If proprietary headers and trailers are added to media streams, then devices can implement custom functionality, but the media streams become incompatible across different devices and networks
Solution Approach 1:
The reconstruction system extracts and removes proprietary headers and trailers from modified media streams, separating the custom functionality additions from the core media stream data. By taking out the proprietary elements that cause incompatibility, the system recovers the original standard media stream that can be transmitted across different devices and networks without compatibility issues.
3Adaptability or versatility
If media streams are modified by adding headers or trailers, then proprietary functionality can be implemented, but the original media stream structure is altered and becomes unusable to standard applications
Solution Approach 1:
The reconstruction system performs preliminary processing of modified media streams by identifying and removing proprietary headers and trailers before the streams reach standard applications. This preliminary action restores the original media stream structure, ensuring that standard applications can process the streams without needing to understand proprietary modifications, while still allowing proprietary functionality to be implemented in the modification stage.
