Digital Audio Interstitial Errors: Raising Awareness And Developing New Methodologies For Detection
It is abundantly clear that a primary component of legacy audio preservation and access is digitization. Recognition of this fact has promoted en-masse digitization of legacy media. Recent years have proven to be very productive in the way of creating best practices and standards for audio preservation and digitization. However, as usual the devil is in the details and there are still some issues to resolve. One such area of concern is integrity issues which exist within the digitization process materializing in one form as “Interstitial Errors”.
Wrappers And Codecs: A Survey Of Selection Strategies
Chris Lacinak – AudioVisual Preservation Solutions
Carl Fleischhauer – Library of Congress
Isaiah Beard – Rutgers University
Hannah Frost – Stanford University
This session consults some of the leading thinkers in the field to help answer one of the most widely asked questions in archives today: What preservation master file format should I use for digitizing analog video? Three case studies will be presented that will walk the audience through the decision-making process, address the special considerations specific to each organization, and relate final outcomes when answering this question. Carl Fleischhauer represents the Federal Agencies Audio-Visual Working Group and their project to document target formats for digital video preservation, focusing here on the MXF wrapper and on JPEG 2000 and uncompressed picture encodings. Isaiah Beard discusses the selection of AVI Uncompressed as part of the recommendations for the Rutgers Community Repository. Hannah Frost discusses the decision-making process behind the selection of QuickTime Uncompressed for the Stanford University Libraries and Academic Information Resources Preservation Lab.
Funding Outside Of The Box
As AV archives work to digitize legacy works and increasingly acquire born-digital works, the sustainability of these rapidly growing digital collections is a new and intimidating challenge. Digital works require ongoing management if they are to survive beyond a few years, which means securing steady funding to keep servers running, to ingest content and update metadata, and to stay abreast of evolving user expectations for online access. The costs associated with these activities are not trivial. New business models for AV archives are essential for sustainable digital preservation. New workflows are needed to make preservation and access more efficient and cost effective. Panelists will discuss a number of innovative and effective sustainable funding and revenue models, which will not only help AV archives keep the lights on, but also enable us to compete and even shine in the fierce world of online video, while offering unique materials and unparalleled value.
Embedded Metadata: A Look Inside Issues And Tools
Metadata is an integral component of digital preservation and an essential part of the digital object. Files without appropriate metadata are not understandable, interpretable, or manageable. Effectively, there is no preservation or meaningful access without metadata.
This presentation explores recent studies and advancements focusing on embedded metadata, or metadata that is stored in the file itself. While this session is audio-centric, we believe that these studies and advancements lay the foundation for work to be performed addressing similar needs in the video domain.
