    摘要： A video signal processing circuit of motion adaptive type includes a circuit for identifying motion of a picture in a video signal on the basis of a difference signal between at least a line signal appearing in an M-th field and a corresponding line signal appearing in an (M-1)th field so that, when a scanning line produced on the basis of the video signal is interpolated between scanning lines of the video signal to improve the picture quality, a signal for interpolating said scanning line is produced in a different manner depending on whether a portion of the video signal to the displayed is a still picture or a moving picture. The motion identifying circuit comprises a horizontal filter spreading the difference signal in the horizontal direction, a circuit delaying the output signal of the horizontal filter by one field after attenuation, a line memory delaying the output signal of the attenuating and delaying circuit by one line, and an output circuit generating a signal identifying the motion of the picture on the basis of the output signals of the horizontal filter, attenuating and delaying circuit and line memory.

    摘要： In a .phi..sub.2 cycle steal mode, a clock signal is selected such that a time period during which a RAM is connected to a timing signal generator for display is extended and a time period during which the RAM is connected to a CPU is shortened accordingly, without changing an overall period. This clock signal is used to actuate a switching circuit for the RAM while a clock signal having unmodified duty ratio is applied to the CPU, a ROM and external circuits so that a display data readout period from the RAM is extended without affecting the CPU clock frequency and the operation of other circuits. During this readout period, a plurality of display address signals are applied to the RAM from the timing signal generator and a plurality of data derived from the RAM are sequentially loaded in a register which is then read out at a desired timing to enable the display of a plurality of characters in one CPU clock period.

    摘要： A method for presentation of information of a recorded television program for allowing user to seize easily and quickly content/composition thereof, and an easily manipulable interface therefor. Picture signal of a television program currently being recorded by a VTR or the like is converted into a frame-based picture signal. Frames indicating inter-shot transitions are detected and stored as shot-representative pictures for thereby generating a digest picture file composed of a set of the shot-representative pictures substantially simultaneously with recording operation of the VTR. In a digest picture display, the shot-representative pictures are displayed in a temporally sequential order in which they were generated in such a form that a predetermined number of shot-representative pictures are displayed in each of predetermined time zones in a uniform array, for facilitating comprehension of the contents of the television picture as recorded. Additionally, by selecting one of the shot-representative pictures being displayed a temporal position of the television picture from which reproduction is to be started can visually be determined.
