    摘要: 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.

    摘要: A video signal processing circuit for producing a still image picture which can be reduced memory capacity. A digital video signal is divided into higher-significant bit and lower-significant bit which are stored in separate addresses of a memory device. The higher-significant bit data is written in the first address. The lower-significant bit data and an identification data signal are written in the following addresses when the present higher-significant bit data is the same as former higher-significant bit data written in the previous address. The lower-significant bit data and a higher-significant bit data of 1 bit are written in the following addresses when the present higher-significant bit data is different from the former higher-significant bit data of the previous address. When the data read from the memory device are the higher-significant bit data, they are compared with the previously read higher-significant bit data, and the lower-significant bit data is produced in a certain value and then the produced lower-significant bit data and the higher-significant bit data read from the memory device are combined to be outputted as a complete video signal. When the data read from the memory device is a lower-significant bit data, the latest higher-significant bit data stored in the previous address is combined with the read lower-significant bit data to be produced as a complete video signal.

    摘要: 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.

    摘要: A television signal receiving apparatus and method is provided having channel decode means for receiving a signal with a video signal, a sound signal, a data signal, and additional data multiplexed to perform tuning, demodulation, and error correction on the received signal and a demultiplexor for separating the multiplexed signal to output coded data of each of the video signal, the sound signal, and the data signal and for extracting service information as one of additional data. A storage device is provided for storing the service information extracted from the demultiplexor, together with a write controller for controlling writing into the storage device, and a read controller for controlling reading of the storage device according to a user command entered by a user. A source decoder is also provided for decoding the coded data outputted from the demultiplexor using the information outputted from said storage device to output the video signal, the sound signal, and the data signal. The storage device records the service information supplied from the demultiplexor, and the read controller performs control such that necessary data are read from the storage device as required by the user, thereby enhancing the speed of processing associated with the service information to provide a quick response to the user requirement. Also, the write controller can control storage such that only necessary information for the next processing operation is stored, thereby reducing the size of the storage device which is necessary.

    摘要: 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. A switch selects the output of a scrambled digital signal from a stage prior to the descrambler, or a descrambled digital signal from a stage subsequent to the descrambler, depending on the changeover control signal from the CPU. Thereby, a scrambled digital signal output or descrambled digital signal output can automatically be changed over depending on a program provider's policy.
