  • Patent number: 5406625
    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.

  • Patent number: 5289285
    Abstract: In a CS broadcast receiving system, when a station is to be selected, an AFC process is first performed with the frequency in the tuning circuit adjusted in units of a coarse frequency adjustment value for reception of a CS television broadcast signal. When a receive signal to be selected by the tuning circuit is not the CS television broadcast signal, the AFC process is performed with the frequency in the turning circuit adjusted in units of a fine frequency adjustment value for reception of a CS.With this arrangement, it is made possible to increase the tuning accuracy when tuning in to the CS sound broadcast signal, while the time required for tuning is shortened and the waiting time reduced when tuning in to the CS television broadcast signal and, thereby, both the requirements for reception of the CS sound broadcast signal and for reception of the CS television signal can be satisfied.
