Abstract: In an integrated circuit in which data can be read out from a memory (107) by supplying control data through an access port (101), this integrated circuit includes an access detecting circuit (111) for detecting an access using the access port (101) and an output inhibit circuit (120) for inhibiting the output of data from the memory (107) when this access detecting circuit 111 detects the access. Therefore, in the integrated circuit in which data can be read out from the memory (107) outside of the integrated circuit by a standardized protocol, the reading of data that should be made unintelligible can be limited.

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.
