Digital technology entered the television domain about 20 years ago, replacing progressively and unavoidably analogue television. Digital has introduced lot of changes in the audiovisual domain and therefore archiving: new technical systems, new uses, new delivery modes… This digital world evolves very fast:
•Files have totally replaced video and audio tapes
• there are new uses with new technical environment : image resolution and sound have evolved and are still evolving : from SD to HD to Ultra HD/4K to 8K and sound from mono to stereo to Surround sound
•Servers and networks have replaced physical media like video and audio tapes.
•There is a great variety of file essence and wrapper standards
•Storage means are in constant evolution in capacity and speed.
For the archivists, the dilemma in this changing context is:
•How to ensure everlastingness of my assets/contents?
•How can I be sure that my format and technical choices are the right ones? What are the criteria?
•How to ensure integrity of data? What are the risks? What are the tools and methods to apply?
The presentation will draw the current situation and some guide lines or best practices to answer these questions.
