Next, by instructing a specific channel or program (for example, a so-called pay-per-view program or channel, or a movie with a specific high viewing fee) by the instruction unit 404, the user is forced to watch the channel or program when watching the program. Connect the switch 801 to the b side, and
By enabling the answering machine function of No. 3, the television is not interrupted by the telephone. In FIG. 8, if an ordinary telephone is connected to the connection terminal 803 instead of the answering machine 804 and the changeover switch 801 is set to the a side and the switch 802 is turned on, the telephone will ring even if there is an incoming call. do not do. If there is an incoming call in this state, the incoming call and the outgoing telephone number of the other party are displayed on the screen of the display unit 110 or by voice, and when the receiver is picked up, the switch 801 is set to b.
It is also possible to switch to the side and make a call. This operation may be performed continuously when the power of the receiving apparatus is turned on, or may be automatically performed when a specific program or channel is being viewed as described above. Alternatively, the operation mode may be turned on / off by a remote controller or the like. In addition,
When the switch 801 is on the a side and the switch 802 is on,
When making a call using the answering machine 804 or the telephone connected to the connection terminal 803, when the receiver is picked up, DC flows to the hook detection unit 805. When this is detected, the switch 801 is turned to the a side and the switch 802 is turned off. do it.
