Abstract: PURPOSE:To ensure the automatic switching of circuits with a simple constitution when the voice multiplex TV signal is reproduced, by superposing the pilot signals on different voice tracks along with the voice signal in accordance with each voice multiplex mode for recording. CONSTITUTION:The voice multiplex TV signal receives the wave detection through a wave detecting circuit 3, and the video signal is recorded on a tape T by a rotary magnetic head 6 via a recording circuit 4. While, the signal received the wave detection through an FM wave detecting circuit 12 is applied to a matrix circuit 18 after the subchannel voice signal SS is extracted via a BPF14, an FM wave detecting circuit 15, etc. as soon as the main channel voice signal SM is extracted via an LPF13. At the same time, the control signal that passes the BPF19, 21, 22, etc. and in accordance with the stereo mode, the voice multiplex mode, etc. is applied to the circuit 18. Then the pilot signal in accordance with the voice multiplex mode is superposed on the voice signal to be recorded on two sets of different voice tracks via the circuit 18. As a result, the switching of circuits is automatically carried out in accordance with the multiplex mode based on the pilot signal in the reproduction mode.

Abstract: PROBLEM TO BE SOLVED: To display an electronic program guide or the like independently of a state of a switch. SOLUTION: When a remote command transmitter 2 or the like is used to make display command of an electronic program guide, a microcomputer (μcon) 13 selects a 2nd switch SW2 to the position of a VTR, then the electronic program guide data decoded by the μcon 13 are sent to a television receiver 23 via the SW2. Simultaneously the μcon 13 sends a remote command code to select a channel to a light emitting section 22 to select a channel of the television receiver 23. Thus, the electronic program guide is displayed on the television receiver 23.

Abstract: PURPOSE: To facilitate operations of various kinds of broadcasting mode settings by recognizing types and operations of each AV equipment forming a system and controlling them with a controller while setting addresses of them. CONSTITUTION: The controller 14 of a television receiver 1 becoming an AV center and controllers 23, 33, 43, 53, 63, and 72 of respective AV equipments 2 to 7 are bi-directionally connected with buss 9. The controller 14 recognizes where respective controllers are, what kinds of operations are possible and how signal paths are made by using addresses. Moreover, the controller 14 controls mode settings such as stereo broadcasting, bilingual broadcasting, dubbing and operations of each equipment 2 to 7. The controller 14 forms signal paths by transmitting addresses to AV equipments 2 to 7 becoming sources and to AV equipments 2 to 7 becoming destinations based on recognized contents to set respective modes. Thus, mode setting is easily performed.

Abstract: PURPOSE:To instantly discriminate index information and hence to improve operation convenience by forcibly displaying the index information during a given period of time when a cassette incapable of recording is set by an erasing preventing member. CONSTITUTION:When a tape cassette which is under the incapable state of recording is set by the erasing preventing member, and when the incapability of recording is detected by an erasing prevention detecting circuit 25 with a control of a control circuit 24, the reproducing state is automatically effected, for instance, for one sec. During this time, the index information in recorded information is read out, and data such as, for instance, the date, time and chapter, etc., is supplied via a display circuit 19 to a television monitor 20 to be displayed by an index decoder 22 at the time of operating an operating panel 23. Consequently, whether a magnetic tape 2 is recorded with the index information or not can instantly be discriminated, while the whole information can be confirmed, and hence the operation convenience is improved.

Abstract: PURPOSE:To prevent considerably the effect of jitter, etc. without changing such as a truck pattern by applying phase detection to a pilot signal with a regenerative synchronizing signal related to a vertical synchronizing signal when reproducing and obtaining a control signal corresponding to the pilot signal. CONSTITUTION:The pilot signals Pb and Pc are separated from voice signals Sb and Sc in band pass filters 31 and 32. The control signal CP is counted down in a counter 34 to the half to form a since wave signal CW, and supplied to multipliers 35 and 36 together with the pilot signals Pb and Pc separated in the filter 31 and 32 to perform multiplying process for phase detection. The two multiplied outputs are then supplied to the third multiplier 37, and then to a three-value comparator 39 through a low pass filter 38 to form the control signal corresponding to the level of the multiplied output. This permits the fluctuation of regenerative control signal CP against the fluctuation of time base of the pilot signals Pb and Pc by jitter. Therefore, this removes the affection by jitter on the multiplying process for the phase detection, and the pilot signal can be detected correctly against jitter.

Abstract: PURPOSE:To realize the control of reproduction in accordance with the multiplex mode with a simple constitution, by superposing the pilot signals of different frequencies for recording along with the voice signal of the voice multiplex TV signal in accordance with the multiplex mode. CONSTITUTION:The voice-related signal separated from the received voice multiplex TV signal receives the wave detection through an FM wave detecting circuit 12 and is separated to the main channel signal SM and the subchannel signal SS via an LPF13 and a BPF14 respectively. The the voice multiplex mode is detected by a BPF19, narrow band BPF21, 22, etc., and a changeover switch 34 is controlled via a switch signal producing circuit 23 to select the signals of different frequencies in accordance with the voice multiplex mode. The selected signal is mixed with the signal SS, etc. by a mixer/synthesizer 25 and superposed on the voice signal on a voice track of one side of a magnetic tape T in the form of a pilot signal. In the reproduction mode, the reproduced voice signal is controlled by the reproduced pilot signal. In such way, the control of reproduction is possible with a simple constitution in accordance with the multiplex mode.
