Abstract: A boundary position detection apparatus in which the position of an imageless part (containing no meaningful image information) lying at the upper part or/and the lower part of a picture is precisely detected from a video signal. A line decision circuit decides whether each of lines constituting the picture belongs to an image part (containing meaningful image information) or to the imageless part. A boundary decision circuit decides the boundary between the image part and the imageless part. A time integration circuit integrates the detected boundary positions temporally, and determines a final boundary position. A detection control circuit finds an image-part region from the final position, detects the average luminance of the region and controls the integrating time interval of the time integration circuit with the average luminance.

Abstract: An arrangement to automatically change between a scrambled digital data output and descrambled digital data output of a receiver by inserting a control signal conforming to a program provider's policy into a transmission signal. In a receiving side, a descrambler descrambles a channel-decoded signal, a demultiplexer demultiplexes the multiplexed signal from the descrambler into encoded video and audio data for output to a source decoder, and extracts the control information inserted in the transmitting side for output to a switch or CPU. The CPU decrypts a control signal from the control information extracted by the demultiplexer to determine whether the scrambled digital signal or descrambled digital signal is appropriate for output, and outputs a changeover control signal depending on the result of decryption.

Abstract: To provide an image which is matched with an aspect ratio of a screen of a display unit by compressing and enlarging the whole of the image to a desired size. A video signal is sequentially written into a field memory in response to a write clock from an input terminal. A clock generating circuit supplies the field memory with a read clock having a frequency which is about 4/3 times as high as that of the write clock. A vertical enlargement control circuit reads a video signal from the field memory with a line period corresponding to a magnification factor and inhibits writing to a one-line memory with the same period to provide a line delayed output for an output signal from the field memory. A vertical interpolating circuit generates a scanning line signal by an interpolation operation in accordance with a control signal from the vertical enlargement control circuit.

A non-standard signal is beforehand processed so as to separate Y and C signals, and the signal thus processed is input to a motion-adaptive processor to thereby reduce a deviation in center of gravity between a still picture signal and a moving picture signal on the timebase to thereby suppress unnatural motion of the picture.

Abstract: In a television receiver in which scanning for an incoming video signal is performed at a frequency n times as high as the input horizontal synchronous frequency by suitably controlling writing and reading on its video memory, the signals for writing and reading on the video memory unit are generated by a horizontal synchronization/deflection circuit. The horizontal synchronization/deflection circuit is arranged by having a clock generation/synchronous deflection circuit for generating reference signals to control the writing and reading on the video memory unit provided with a phase comparator such that a horizontal drive signal to drive a horizontal deflection circuit and a flyback pulse are brought in phase.

Abstract: There is provided a detection circuit for TV receiver which includes a frame comb filter and a field comb filter and which generates a luminance signal or a chrominance signal by effecting addition or subtraction upon video signals of two frames adjoining each other included in the received TV signal. This detection circuit includes a synchronization separation circuit, an APC circuit, a frequency division circuit connected to the APC circuit, and a comparator circuit connected to the frequency division circuit. The frequency of the chrominance subcarrier signal is demultiplied by the frequency division circuit. The phase of the chrominance subcarrier signal thus frequency-divided is compared with the phase of the synchronizing signal separated by the synchronizing separation circuit. It is thus judged whether the received TV signal is a standard TV signal or a nonstandard TV signal.
