Abstract: PURPOSE:To make a reception mode at scramble decoding clear. CONSTITUTION:Scramble on/off information of a voice signal and voice mode information are fed to a microcomputer 3 from a PCM demodulation circuit 11. The microcomputer 3 discriminates whether or not scrambling is decoded based on the scramble on/off information in the voice signal. When it is discriminated that the scrambling is decoded, the PCM demodulation circuit 11 is controlled to mute the voice. Moreover, in this case, a display data DCH of a channel and voice mode is supplied to a video signal processing circuit 7 to display the channel and voice mode onto a picture tube 8. Thus, the reception mode at the time of scramble decoding is made clear.

Abstract: PURPOSE:To correctly recognize the state of an equipment by displaying a message showing that a power supply voltage is not supplied to a BS converter, on a display means when a changeover switch is not in an OFF state at the time of newly providing the satellite broadcasting equipment. CONSTITUTION:A control means 20 is provided to supply the power supply voltage from a BS tuner 27 through a signal transmission line 9 to a BS converter 10 and to display a menu function on a display means 18. This control means 20 is equipped with a judging means to judge the ON/OFF state of a switch 21, which regulates supply of the power supply voltage to the BS converter 10, provided in the BS tuner 27 and to judge the presence/absence of a BS broadcasting. When a judging means 20 judges that the switch 21 is in the OFF state and the BS broadcasting is absent, the display means 18 displays that the power supply voltage is not supplied to the BS converter 10. Thus, trouble caused by the mishandling of the changeover switch 21 is prevented.

Abstract: PURPOSE:To simplify the operation by applying the control to output a content screen when a command signal by a character key is detected at the teletext broadcast mode. CONSTITUTION:A system controller 7 outputs a control signal so as to output a content screen on the screen when an operation command signal from the TV broadcast into the teletext broadcast is detected and the state of the teletext broadcast selected already is confirmed by a mode discrimination means 7C and the information is sent to an operation control means 7B. Thus, the operation of character keys is an operation to obtain the program screen for the teletext broadcast at all times and at least the content screen is obtained by using the character key. Thus, when the program screen of the teletext broadcast is desired to be watched, the character key is to be operated for the time being in any case and the operation by the user is simplified.

Abstract: PURPOSE:To facilitate the confirmation of the setting state by applying the screen display representing the present setting state when a command signal is fed in a 1st period and applying the screen display while the setting state is switched when a command signal fed in a 2nd period. CONSTITUTION:When a noise reduction on/off key is depressed while no screen display is applied, the present noise reduction on/off key state is displayed. When the noise reduction on/off key is depressed while screen display is applied, the on/off state of noise reduction is switched and the on/off state of noise reduction after the changeover is displayed. Thus, if the on/off state of noise reduction is not clear, the noise reduction on/off state key is depressed to detect the present noise reduction on/off state.

Abstract: PURPOSE:To omit an operation to return a mode to a television mode without a confusion at the time of tuning by a user when a superimposed program ends by automatically switching the mode to the mode just before the superimposed program is selected at the time when the superimposed program ends. CONSTITUTION:To a storing means 16, the mode before the superimposed program selection is stored. A microcomputer 13 decides whether the superimposed program ends or not. In a condition in which the superimposed program ends, whether the mode before the superimposed program selection stored in the storing means 16 is 'character' or 'television' is decoded, the said mode is transferred through a control line 13b to a character signal processor 14, the status signal of the character signal processor 14 is made into the mode before the superimposed program selection, and thereby, an R, G, B switching circuit 10 executes a switching action. In such a way, since, when the superimposed program ends or when the user switches channels, a character broadcasting receiving mode or a television receiving mode can be made, the user cannot be confused at the time of the selecting operation of keys.

Abstract: PURPOSE:To discriminate from which station the teletext broadcast comes by devising the device such that it is confirmed by the depression of a screen display key as to which channel of teletext is being received when the mode is switched from the external video signal reception mode into the teletext signal reception mode. CONSTITUTION:With a teletext key depressed, a microcomputer 13 controls a video control signal 14v and a voice control signal 14s so as to throw switches SW1, SW2 to the position of the TV terminal via a teletext processor 14. Simultaneously, an RGB changeover circuit 10 is thrown to the position of the processor 14 to establish the teletext reception mode. With a screen display key of a remote control operating means 17 depressed in this state, the computer 13 controls a teletext signal generating circuit 16 to extract a channel number of a teletext broadcast station received at present and gives the number to the circuit 10 via the circuit 16. Thus, the channel number is displayed on the screen of the display means 11.

Abstract: PURPOSE:To listen to the voice of the opposite party in an excellent way even during a period from the hook-off of a handset till the contact of it to the ear by interrupting a received voice signal supplied to a speaker when the handset is hooked off till a prescribed time elapses. CONSTITUTION:With a handset 2 hooked off, a detection signal 10a is outputted from a hook switch 10 and given to a control means 11. The detection signal 10a outputted from the hook switch 10 is given to a delay section 12 and supplies to a speaker switch control section 13 with a delay of several seconds. Thus, the received sound voice is outputted from a speaker 3 during the period A and from the receiver 2 during a period B, the voice is outputted overlappingly from both the speaker 3 and the receiver 2 during the period B. Thus, the absence of voice from the hook-off of the receiver 2 till the contact to the ear is avoided and smooth talking is applied.

Abstract: PURPOSE:To adjust to a just tuning state with all receiving band by correcting an AFT voltage according to the switching of the receiving band. CONSTITUTION:The correction means of the AFT voltage EO is disposed, and the AFT voltage is corrected according to the switching of the receiving band. For instance, when a(c) band is switched to a (ku) band in a receiving, an offset voltage VO is raised by a prescribed value according to this switching. For instance, when the receiving is switched from the (c) band to the (ku) band, the AFT voltage EO is raised by the prescribed value. According to the switching, when the offset voltage VO is raised by the prescribed value, the raised part of the AFT voltage EO is offset. Accordingly, when the receiving is switched from the (c) band to the (ku) band, an ATF operation is correctly carried out.

Abstract: PURPOSE:To improve the operability of a slave equipment by reading sound format information of all receptible channels at a satellite from a memory every time a received satellite is changed and transferring the information to other receiver. CONSTITUTION:In case of the change of satellite, sound format information Di1-Din of all receptible channels by the selected satellite is read from the memory 60 and the information Di1-Din is enabled to be transferred to other receiver. Thus, as the other receiver, even if a receiver having a small capacity of memory is provided, which can only store all receptible channels by one satellite, when the satellite is changed, the sound formats of all the channels of the changed satellite are transferred to the small capacity of the memory. Thus, the sound tuning is not especially required.

Abstract: PURPOSE: To easily confirm a position where the polarizing plane of an antenna coincides with that of the broadcast wave of a receiving channel without being affected by the broadcast wave of an adjacent channel, by adjusting the porolarizing plane of the antenna based on a difference between the signal levels obtained in the states that the broadcast waves of the receiving channel, and the adjacent channel are channel-selected respectively. CONSTITUTION:Detecting means 3, 4, 5, and 6 which detect the difference between the signal levels of the broadcast wave obtained in the state that the broadcast wave of the receiving channel CH2 is channel-selected, through a channel selection circuit 2, and the broadcast wave obtained in the state that the broadcast wave of a CH1 adjacent to the broadcast wave of the CH2 is channel-selected, through the channel selection circuit 2, is provided, and the polarizing plane of the antenna is adjusted to the broadcast wave of the CH2, based on an obtained detected result. In this way, it is possible to easily recognize the position where the polarizing plane of the antenna coincides with that of the broadcast wave of the receiving channel, even when the signal level of the broadcast wave of the adjacent channel CH1 is large.
