摘要： A scrambling system for an audio frequency signal is disclosed which employs a timebase-compressing and/or expanding system to measure the compressed and/or expanded amount of a segment time length caused in a transmission recording and reproducing system. In the scrambling system of the present invention, a marker signal is inserted into a portion between the adjoining segments and transmitted from an encoder side to a decoder side, while at the decoder side, this marker signal is detected, the synchronization is achieved by this marker signal along the compression and expansion of the segment length and the respective segments are rearranged to the original correct order. Thus, the connected portion between the segments can be made smooth so that it is possible to obtain the scrambling system for an audio frequency signal having high accuracy and high reliability.

摘要： A scrambling system for an audio frequency signal in which an audio signal is divided into blocks, each block being formed of a plurality of frames, the plurality of frames are rearranged on a timebase in a predetermined order at every block so as to be encoded and the encoded signal is re-arranged on the timebase in an original order so as to be decoded, in which there are provided a first signal processing circuit for inserting a redundant portion into a portion between adjoining frames and timebase-compressing the frames in response to the redundant portions upon encoding, a control signal generating circuit for inserting a control signal other than an audio information into the redundant portions, a control signal detecting circuit for detecting the control signal upon decoding and a second signal processing circuit for removing the redundant portions in synchronism with the detected control signal and timebase-expanding the frames in response to the redundant portions. Therefore, even when the audio signal is transmitted through a system in a transmission path having a timebase fluctuation such as a transmission path of a VTR (video tape recorder) and the like the frequency band region of which is restricted, the signal waveform is not distorted and a noise is not mixed therein so that the scrambling communication having high quality and high reliability can be presented.

摘要： This invention relates to an information delivery system and method, an information transmission apparatus and method, and an information receiving apparatus and method for delivering a digital multi-channel service signal through a satellite and a cable network. A QPSK demodulation circuit demodulates an inputted TS and outputs it to an error correction circuit. The error correction circuit corrects the inputted signal and outputs it to a network information (NIT) conversion circuit. The NIT conversion circuit replaces the NIT for CS waves with NIT for cable TV and outputs it to a QAM demodulation circuit. The QAM demodulation circuit demodulates the inputted signal and pouts it to a frequency conversion circuit. The frequency conversion circuit converts the frequency of the inputted signal into a predetermined value and outputs the signal to a signal mixer.

摘要： A noise-squelching circuit in which a phase-locked loop supplies an identifiable output signal that distinguishes between those times when the voltage-controlled oscillator in the loop is locked onto an incoming carrier, and those times when it is not. This identifiable signal controls a muting circuit to allow the information modulated onto the incoming carrier to pass through the muting circuit to an output terminal only when the loop is locked to an incoming signal but not when the loop is not locked onto a carrier.

摘要： An information transmitting system capable of two way communication, suitable for use in transmitting information signals between a central control unit and a plurality of terminal apparatus units. Each terminal apparatus unit may be located at a different passenger seat in an aircraft, a train, a bus, or the like. The signals transmitted from each terminal apparatus to the central control unit are transmitted by way of two channels. In one operating mode, one channel is used as a random access channel, and the other is used as a polling channel. When polling transmission is not effected, the polling channel is used as a second random access channel, so that the system may efficiently transmit many information signals on two random access channels.

摘要： In tuning apparatus, a sensor senses when a tune indicating signal has been produced by the IF section so as to enable an adjusting circuit to change the tuning condition of the apparatus by a predetermined frequency step and then to disable the adjusting circuit if the tune indicating signal still is sensed following this frequency change so as to maintain the last-attained tuning condition. Alternatively, if the tune indicating signal no longer is sensed after the tuning condition has been changed by the predetermined frequency step, the tuning section is returned to its preceding tuning condition by this predetermined frequency step. Consequently, if the received signal is a high level signal at a frequency within a predetermined range from a broadcast frequency, the tune indicating signal is produced when the tuning condition of the tuning section differs from the broadcast frequency by this predetermined frequency step; and the tuning condition then is changed by this step so as to arrive at the desired broadcast frequency. If, however, the received signal is a low level signal, the tune indicating signal is produced only when the tuning condition of the tuning section coincides with a desired broadcast frequency, and then this tuning condition is changed by one step followed by a return of one step to the proper condition.
摘要翻译：在调谐装置中，传感器感测IF部分何时产生乐曲指示信号，以使得调整电路能够以预定频率步长改变装置的调谐状态，然后如果调谐指示在该频率变化之后仍然感测到信号，以便保持最后达到的调谐条件。或者，如果在调谐条件已经改变了预定频率步长之后不再感测到调谐指示信号，则调谐部分通过该预定频率步长返回到其先前的调谐条件。因此，如果接收到的信号是从广播频率的预定范围内的频率的高电平信号，则当调谐部分的调谐条件与广播频率不同的预定频率步长时，产生乐曲指示信号; 然后通过该步骤改变调谐条件，以达到所需的广播频率。然而，如果接收到的信号是低电平信号，则仅当调谐部分的调谐条件与期望的广播频率一致时才产生调谐指示信号，然后将该调谐条件改变一个步骤，然后返回一步到适当的条件。
