Abstract

PURPOSE:To discriminate a descrambler and to promote a proper processing at the time of a non-connection by transmitting the key data of a prescribed level to a tuner from the descrambler at the time of switching to the receiving mode of a scramble signal. CONSTITUTION:When a receiving program is switched from a free broadcasting program to a charged broadcasting program and a control code PAY meaning a charge is applied to a controller 20, a switch circuit 21 is switched and a control code CC meaning a free broadcasting is applied to a control output terminal. Thereafter, a switch circuit 22 is switched to fetch a decision signal CNE from a descrambler connection decision circuit 24, light a display lamp 26 when it is in the non-connection state and maintain a muting state at the time of charged boardcasting. ON the contrary, when it is in the connection state the muting state is cancelled to apply the sound signal of the charged broadcasting to a sound output device 19. At the time of receiving a scramble broadcasting program, when the descrambler 2 is not connected, it is displayed. Thereby, that the receiving is impossible can be recognized by a user.
