 Furthermore, it is also possible that a technically known but economically not yet relevant kind of use could be part of a contract if specifically named and explicitly agreed upon between the parties.According to jurisdiction, contracts on yet unknown types of use (representing a so-called business of risk) are only effective if such a type is specifically named, explicitly discussed and agreed upon in the contract; never does this form a part of the general terms and conditions.As kinds of independent and formerly not yet known types of use exploitation on e. g. narrow-gauge film, on video and via video on demand are all recognised by the legislator.
