Digital Media Storage

Storing digitized audio and video from the Montreux Jazz Festival archive onto a 3 x 4.7PB Active Archive System by HGST and LTO tapes as backup.

Hard-disk storage is used for providing an immediate access to the archive as advantages to this technology include streaming of multiple media, automatic backup, redundancy, integrity check, automatization of workflows and all life-cycle processes of archive mainenance. After digitization of the Montreux Jazz Festival archive, media files are supplied to EPFL on LTO tapes for storage and meta data ingestion.

As described in the digitization process, the Montreux Jazz Festival digital archive consists of an uncompressed primary version which remains untouched and a secondary slightly compressed version for broadcasting, post-production and streaming purposes. In 2011, an innovative archive solution based on hard-disk and LTO tapes was implemented at EPFL for preservation and access to the Montreux Jazz Festival digital archive.
