Abstract
A determination is made whether recording by a recording apparatus is or is not feasible. This determination is made on the basis of whether or not scrambled reception signals can be descrambled. Recording is discontinued when it is determined that descrambling is not feasible. This prevents wasteful recording. A user can check visually and/or audibly to see whether or not descrambling has been effected. The user is thereby apprised of whether or not recording is carried out.
