The following document describes the use case applications for the ivitec MediaSeeker Core Platform, pertaining to video-based fingerprinting and its functional extensions within the post-production and archive environments.
Improving Management of Media Archives
1. Ensuring media is “universally identifiable” through consistent metadata: Assets in archives are often plagued with inconsistently applied metadata for files that did not conform to a pre-established process. By using ivitec MediaSeeker to create a unique and permanent finger- print, the presence of a fingerprint database enables a return to the highest definition source material regardless of whatever subsequent resolution or formats were used during the content creation process.
2. Reconciling mismatched timecodes: During the media production process, via the use of standard external house sync generation or other forms of master timecodes, video, audio,
and resulting files stay synced to this external reference and are archived with the original time-code intact. However, once content is broadcast, it is often the case for the receiving-end entity to copy an on-air program and impair sync due to latency associated with both the over-the-air transmission and/or the decoding chain at the receiving site. If no house sync or master timecode is present, then the timecode could potentially become corrupt. By using fingerprint comparisons between the source and the target, timecodes can be reconciled and repaired.
3. Detecting duplicate or down-resolution versions in the archive: Consider a production that has been previously archived and is checked out for inclusion in a new project. After the new project is completed, the new work is procedurally checked into the archive. However, the source material may be largely duplicative resulting in wasting costly storage space. Using fingerprinting, duplicate files with minimal changes (e.g. transcoding, re-encoded, subtitled, etc.) may be identified and subsequent decisions can be made whether to retain those files in the archive, thus eliminating unnecessary storage and duplication. Similarly, once fingerprinted, archived elements that are reused and edited into highlight reels may be identified and linked back to their original source footage, enabling intelligent decision-making and other forms of metadata augmentation.
Improving Operational Efficiency
4. Detecting and locating high-resolution source material: Often, post-production starts its process by searching a DAM and viewing proxies of cataloged content. By using a finger-printing comparison process, high-resolution source material and other variants can be found quickly and automatically, enabling the editing process to begin sooner.
5. Improving versioning and storage efficiency: When programs are exported, “regional-ization” requires the creation of several intermediary files, such as subtitling and language dubbing. To maintain creative control and protect the brand, the media owner will often require that each regional version be returned for audit and archive. By using ivitec MediaSeeker, these regional differences can be identified, isolated, and active decisions made as to which copies and what passages should be retained on the working storage repositories. The practical result of this is that digital fingerprinting enables on-demand recreation and delivery of these alternate versions without cumbersome human intervention.
Enforcing Compliance and Legalities
6. Detecting content with limited production allowances: In distribution agreements, content licenses are typically encumbered with usage rights or time limitations. However, in the case of multiple versions or “highlight shows” the editor often combines scenes from previously aired shows. This reused material may not have the necessary rebroadcast rights and licens-ing information. Lacking such details, ivitec MediaSeeker may be used to run fingerprinting comparisons to search the archive and reveal and propagate the original licensing metadata information from the original source material, thus ensuring compliance before the material is aired.
7. Reverse engineering regional EDLs: To reconcile archived materials for regulatory compli-ance, a fingerprint of the entire production may be used to compare with the individual finger-prints of files used in a compilation, including programs, advertisements, and PSAs. In this manner, the files, cut points, and overall timecode can be reconstructed. The ivitec Media-Seeker Core Platform offers the fingerprinting technology, the comparison engine, and the structured database to perform these tasks in an automated manner.
