Purpose of different formats: acquisition/production formats, patrimonial formats, pivotal formats, delivery/exploitation formats.
Native formats: analogue representation of sound and images,
- native sound formats,
- stills, video, film,

Formats and compression tools: audio (MP2, MP3 audio, AAC, Dolby, FLAC,...), stills (JPEG,...), video (MPEG-2, MPEG-4 / H.264, H.265, VC-1, DivX, Flash, JPEG2000...), film (DCP, DPX), - practical workshop: media transcoding.
Container formats: storage formats,
- transport formats: liaison, exchange, broadcast, streaming,
- focus on HTML5 with flash formats and WebM,
- practical workshop: transforming formats with different tools (open source, professional).
Metadata: types, examples,
- representation (XML), standardising metadata models in the media (Dublin Core, MPEG-7, NewsML G2,...),
- metadata chain.
Principles of digital file archiving and storage:
- choice criteria, storage supports,
- stock management: access, naming, volumes, security, preserving, migration...
