摘要： PROBLEM TO BE SOLVED: To provide a nonlinear video editing system capable of guaranteeing the prevention of occurrence of deviation between video scene and audio scene never deviated from each other. SOLUTION: Pluralities of cut scenes are displayed in time series in parallel with each track on an external display device. The user puts video scenes and audio scenes desiring to warrant same positions over pluralities of tracks on a skewer. In the case that the user operation possibly causing a timewise deviation of scenes on a track put on the skewer is caused, the scenes put on the skewer are moved integrally in a direction of the time base and blank scenes without real data are inserted in blank periods in an optional track caused by the movement. Number of blank scenes of each track is counted for each execution of edit and displayed on a display device. Furthermore, the blank scenes are searched.

摘要： PROBLEM TO BE SOLVED: To provide a nonlinear video editing system capable of executing the user operation usefully in the case of moving an editing point being the border of cut scenes. SOLUTION: This system has 1st, 2nd and 3rd reproduction modes that are selected by the user at reproduction of a video image for editing purpose. In the 1st reproduction mode (PREVTRIM), a 1st cut scene is reproduced before an editing point based on a play list and a 2nd cut scene is reproduced after the edit point based on a play list. In the 2nd reproduction mode (EPTRIM), the 1st cut scene is reproduced continuously before and after the edit point. In the 3rd reproduction mode (NEXTTRIM), the 2nd cut scene is reproduced continuously before and after the edit point. In these reproduction modes, data are reproduced at a variable speed in an optional direction by means of a dial and any of the reproduction modes is selected in one operation by three corresponding keys while making a current position.

摘要： PROBLEM TO BE SOLVED: To provide the nonlinear video broadcast system where a cue of a cue sheet is electronically generated and corrected flexibly, quickly and easily. SOLUTION: A clippers processing is started at a point of time t3 by a preview for a roll R3 placed on a cue sheet acting like a list for progressing programs. Thus, a package P2 having a clipped position among packages of the roll R3 is divided into two new packages P21, P22 at the clipped position. A scene having the clipped position among scenes of the package P2 is divided into two scenes at the clipped position. Thus, the new packages P21, P22 are used as independent packages as edit objects. For example, even when the package P1 has been on the air, the package P2 is edited.

摘要： PROBLEM TO BE SOLVED: To allow the circuit to generate a fractional frequency signal while realizing a shorter lock-in time. SOLUTION: A reference signal generating circuit 10 employs a crystal oscillator to generate a reference signal with a reference frequency. A reference signal frequency divider circuit 21 frequency-divides the reference signal to produce a frequency division reference signal Fdr. A VCO 18 has a 1st frequency control circuit 17 and a frequency of an output signal of the VCO 18 is controlled in response to a control voltage applies to the circuit 17. A phase comparator circuit 12 produces a control voltage in response to a phase difference between a phase of a reference frequency Fr and a comparison frequency Fp outputted from a frequency divider circuit 20. An SSB mixer 30 mixers the output signal of the VCO 18 with the frequency division reference signal to produce a mixed signal. A coaxial dielectric filter DRF 16 passes only a desired frequency component of the mixed signal because its pass frequency band is controlled in response to a control voltage applied to its 2nd frequency control circuit 15. An offset circuit 11 produces an offset between control voltages to be respectively applied to the 1st and frequency control circuits 17, 15 in response to the frequency of the frequency division reference signal.

摘要： PROBLEM TO BE SOLVED: To simplify the direction control by confirming easily a reception status of an antenna. SOLUTION: A video signal separation device 20 is placed between an antenna 10 and a coaxial cable (signal line) 30, and a reception/video signal mixture device 40 is placed between the cable 30 and an image generation device 50. The device 40 supplies the reception signals, existing on the cable 30 to the device 50 and also receives the video signals from the device 50 to supply them to the cable 30. The device 20 supplies the reception signals to the signal line 30 and also separates and outputs the video signals existing on the cable 30. Under such conditions, the device 20 is placed between the antenna 10 and the cable 30, i.e., at a place near the antenna. Thus, it is possible to confirm the reception state of the antenna 10 at a nearby place by displaying the video signals outputted from the device 20 on a compact display device 32.

摘要： PROBLEM TO BE SOLVED: To supply a power with little noise by a method, wherein a required number of capacitors are connected, so as to form a matrix of (i) columns and (k) rows and the range of the output voltage of a charging means is controlled, in accordance with the column number (i). SOLUTION: One or more ranges of the output voltage of a 1st capacitor bank 14 are provided and a row number (k), i.e., the number of capacitors which are connected in parallel to each other, is switched in accordance with the range. Specifically, the higher the voltage of the range, the smaller the number (k) of the rows. Although a current or a voltage with little droop can be outputted, when the row number (k) is large, as the charging value is large when the output voltage of the 1st capacitor bank is high, a current or a voltage with relatively little droop can be outputted, even if the number of capacitors connected in parallel to each other is small. With this constitution, the total number of capacitors of which the 1st capacitor bank 14 consists is not changed within the range of allowable drooping, even if the range of the output voltage is changed.

摘要： PROBLEM TO BE SOLVED: To exactly discriminate the digital phase modulating system of an input signal from unknown radio equipment by finding an estimated carrier frequency from the frequency area data of an unknown digital phase modulated signal, detecting that frequency, operating it, finding the symbol point of phase modulation and displaying data provided by detecting and operating that frequency again. SOLUTION: A down converter 12 converts the radio wave of unknown radio equipment received by an antenna 10 to an intermediate frequency signal and a data spectrum analyzer 14 converts that signal to digital frequency component data and stores them in a memory. Afterwards, a computer 16 finds the estimated carrier frequency from the digital frequency component data in the memory and finds an orthogonal coordinate by detecting and operating time area data based on this frequency. Further, the symbol point of phase modulation is found at the respective points of these coordinate data and a true carrier frequency is found from this symbol point. Then, the time area data are detected and operated again based on the found carrier frequency and the provided symbol point is displayed on a coordinate plane.
