MXF File Blockchain Hash Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The Material eXchange Format (MXF) lacks robust security mechanisms for ensuring the integrity and error-free transmission of digital video and audio media files, particularly during digital transmission over various communication links.
Innovation Solution
Integration of blockchain hash technology within the MXF format to create a secure container that includes metadata and blockchain hash digest information, enabling error checking by comparing the hash digest of the received file with a cloud-based hash digest, ensuring data integrity and authenticity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blockchain hash technology is integrated into MXF format, then data integrity and security are improved, but device complexity increases
Solution Approach 1:
The blockchain hash digest is nested within the existing MXF file structure as metadata, specifically utilizing the SMPTE 423-10 metadata schema. The hash information is embedded in a nested manner within the MXF container, allowing the security feature to be integrated without fundamentally altering the outer structure of the MXF file, thus minimizing complexity increase while maintaining reliability improvement
Solution Approach 2:
The patent introduces an intermediary verification process where the blockchain hash digest acts as a mediator between the media content and the verification system. Rather than directly complexifying the MXF structure, the hash digest serves as an intermediary layer that enables integrity verification through comparison with cloud-based references, resolving the contradiction by adding a functional layer without excessive structural complexity
2Reliability
If cloud-based hash digest verification is implemented, then transmission error detection is improved, but loss of time increases due to cloud access
Solution Approach 1:
The blockchain hash digest is calculated and embedded in the MXF file during the file creation or encoding stage, before transmission occurs. This preliminary action allows the verification process at the receiving end to be simply a matter of comparing the embedded hash with a cloud reference, significantly reducing the verification time during actual transmission while maintaining high error detection capability
Solution Approach 2:
The patent implements a selective verification approach where only the hash digest portion of the file needs to be verified against cloud references, rather than verifying the entire media file content. This partial action approach maintains comprehensive error detection capability while minimizing the time required for verification, as only a small portion of the file (the hash) needs to be accessed and compared
Data Source
AI summary
Digital media that has been blockchained into a blockchain file format may be stored into a secondary file format like a Material eXchange Format (MXF) digital file by deconstructing the blockchain file and storing its subcomponent blockchain data and blockchain hash digests for each block within separate structures of the MXF digital file by generating a table for the blockchain hash digests that links to the blockchain data through data pointers. These separate structures of the MXF digital file are the generic container for a media file and a SDTI-CP (Serial Data Transport Interface—Content Package) compatible system item.
