Audiovisual documents are works comprising reproducible images and/or sounds embodied in a carrier whose;
• recording, transmission, perception and comprehension usually requires a technological device
• visual and/or sonic content has linear duration
• purpose is the communication of that content, rather than use of the technology for other purposes.
