This paper, presented at the 2013 IPRES conference, describes the BBC migration project for its D3 and digibeta videotape collection. The systems used were developed in house by BBC R&D. It starts with a description of the core processing systems and the approach taken for both formats. This is followed by an assessment of the preservation that has been achieved, some of the challenges faced and lessons learnt. The next challenge, migrating the content held on LTO3 data tape to a new storage technology is then considered in Section 3. Section 4 considers the relationship between the archive preservation storage system and the services the archive library needs to provide.
This case study offers a good look at the difficulties of migrating and preserving large and diverse kinds of audiovisual files in a broadcast production environment. It illustrates the pros and cons of in-house tool development, emphasizes the potential value of implementing metadata standards in the workflow, the need to carefully consider when certain preservation checks occur in the workflow (such as generating checksums and performing quality control), and the complications multiple and unconnected metadata systems bring to the preservation process. This paper is of interest to anyone looking for insight into the problems confronting large broadcast archives as they try to implement preservation workflows.
