Preserve authenticity of a broadcast archive across format migration
Can the archive prove an asset's origin and editorial state after storage and codec migrations?
Operational pain
Transcoding and restoration necessarily change files, while old signatures, certificates, metadata, and playback systems expire.
Trigger
Archive digitization, cloud migration, rights dispute, or cryptographic transition.
QNSI contribution
Connect the decision to a controlled security path
Record QNSI-compatible signatures for source asset, preservation master, transformation method, operator, and validation material.
Decision artifact
An archive authenticity chain distinguishing original, preservation, restored, and distribution derivatives.
What still requires validation
Archivists and counsel define authenticity, rights, preservation metadata, acceptable transformations, and retention.
External problem context
Primary sources
These sources establish the external requirement or risk context. They do not endorse HEOSSI or prove that QNSI completed this scenario.
Evidence boundary
What this page does—and does not—prove
This is a product evaluation pattern, not a customer case study, certification, legal opinion, regulator endorsement, or claim that a production deployment completed the described work.
