Video Database Management
The existing video databases are generally little digitized. The progressive passage to digital television should quickly change this point. As a matter of fact, TF1 passed to an entirely digitized production, the cameras remaining the only analogical stage of the production. Treatment, assembly and diffusion are digital. In addition, domestic digital decoders can, from now on, be equipped with hard disks allowing a storage initially modest, of ten hours of video, but larger in the long term, of a thousand of hours.
One can then distinguish two types of digital files. First of all those of the private individuals, including recordings of diffused programs and films taken using digital camcorders. If the effort of management of such bases will be probably weak, without rigorous method, there is a great need for tools to help the user: automatic creation of summaries and synopses to allow to find information easily, or to gain, in a few minutes, a general idea of a program. Even if the service is rustic, it is initially evaluated according to the appreciation which it brings to a system (video tape recorder, decoder), will have to remain not very expensive, but will benefit from a large diffusion.
On the other hand professional files (TV channels archives, registration of copyright, cineclubs, producers...) are of a much larger size, but benefit from the attentive care of professionals of documentation and archiving. In this field, systems can be much more expensive and are judged according to the profits of productivity and the assistance which they bring to documentalists, journalists and users.
