Archiving of finished programmes Clause Samples

Archiving of finished programmes. Distribution is a suitable point in the programme chain at which to take finished programmes to be stored in the archive. The Orpheus project advocates the use of open standards throughout, and BW64 with ADM is the assumption for archiving. This is to ensure that the files remain easy to interpret and decode in future, as codecs (which might be proprietary) come and go. The use of compressed formats (such as MPEG-H) is not recommended for archiving. Even though high bit rates offer excellent audio quality, the possible loss of quality that concatenated coding would incur means that these are not suitable. As stated in another Deliverable, sampling at 48kHz, with 24 bits, is necessary and sufficient for programme production.
