Lectures

On Audio-Visual File Formats

The audio-visual file formats will be the guideline of this lecture which will discuss topics such as sampling, quantisation, compression and colour models. We will delve deep into the file structure and discover for example how video and audio codecs works together in a container. The advantages and the disadvantages of the different file formats will be discussed. (2 hours)

Data Storage and Data Migration

This lecture presents the LTO-based solutions, the most efficient possibility archives have to deal with the large quantities of digital media they must handle today. Not only the technical aspects are considered, but also how this technology can be part of the archival workflow and provide a reasonable level of security. The goal is to master the technology and not to become its slave. (1/2 hour)
