Barcode Scanners, MiniDV Decks, And The Migration Of Digital Information From Analog Surfaces

28 October 2010

Dave Rice and Stefan Elnabli – October 28, 2010

Due to the susceptibility and challenges of both digital and analog carriers, data must be periodically moved from one carrier to another within a preservation process. When analog data is migrated from its original carrier to a new digital carrier, the analog data is ultimately transformed through the process of sampling. Challenges are then posed to authenticating the accuracy of such a migration. Despite the perceptual exactness of an analog source to its digital copy, the analog data and the digital data are never exactly the same. However, in the realm of file-based digital-to-digital migration, exactness can be achieved and evaluated. Within the entirely file-based environment, checksums and data comparison tools can verify that two copies are exact matches or reveal their deviation in a way that is not feasible between analog and digital environments.

IASA/AMIA 2010 Presentations

8 June 2010

AVPS moderated or presented on a number of panels at the 2010 International Association of Sound & Audiovisual Archives / Association of Moving Image Archivists conference in Philadelphia, PA. The topics covered a wide breadth, including embedded metadata, new tools and strategies for digital media preservation, and new approaches to funding and advocacy for collection management.

Digital Audio Interstitial Errors: Raising Awareness And Developing New Methodologies For Detection

6 January 2010

AVPS is involved in leading parallel projects within the Federal Agencies Digitization Guidelines Initiative and the Audio Engineering Society on the development of new standards and tools for performance testing of digital audio systems. As part of this work AVPS is proposing a Comparative Analysis tool which departs from existing error detection tools and is particularly well suited to identifying a particular type of error, labeled here as interstitial errors. This paper by Chris Lacinak uncovers one type of error that can occur and discusses the theory behind the comparative analysis methodology and approach to the development of new tools for test and measurement.

Association Of Moving Image Archivists (AMIA) 2009 Accessioning & Managing Born Digital Video

8 July 2009

Born Digital File-Based Video recording is pervasive. Tape is not even an option on many new cameras being sold today. This shift has made accessioning and management of file based content and the associated challenges a new reality to archives. This presentation offers insights into the challenges that born digital file-based video brings to your archive and strategies for managing it.
