3、ision recording and it has become particularly acute with the introduction of digital technology that allows to produce, post-produce, record and archive all sorts of intellectual products on computer-type supports, which are indifferent to the type of information stored on them; c) that such need i

4、s particularly felt in the case of digital programme archives, which are one of the main assets of broadcasters and often also represent the permanent memory of a nation, its culture and its lifestyle; d) that the use of metadata is clearly the key to providing adequate information on the content of

5、 programme recordings, and would be most useful for this purpose, and notably for the purpose of the international exchange of recorded sound and television programmes, if it were universally used and harmonized, e.g. through appropriate ITU Recommendations based on carefully researched user require
