摘要：入力信号が周波数領域に変換され、サブキャリア周波数に関する周波数成分の対称性が比較される、複合信号復号の方法。この比較は、処理される周波数に依存して変化する。この方法で分離は、入力スペクトルの異なる部分の既知の特性に合うように適応させられ得る。これは、ＮＴＳＣ信号を処理するために特に有用である。クロミナンスへの特定の成分の割当は、対応する空間周波数における複合信号の輝度情報の測定値に依存して片寄らされ得る。

摘要： PROBLEM TO BE SOLVED: To provide a system for multiplexing a plurality of digital services including auxiliary data services. SOLUTION: In a video system for processing compressed video data to obtain composite video data corresponding to a standard composite video signal form selected out of a plurality of standard forms, the system includes a processor 34, and a standard video expander 32 for obtaining expanded video data resulting from processing compressed data, and user data. VBI (vertical blanking interval) data are encoded to the user data and the processor 34 extracts the VBI data from the user data. A video interface 40 processes the expanded video data and the VBI data to provide composite video data. A video interface 40 is equipped with a VBI data generator for processing the VBI data to obtain VBI signal data, and a mixer for receiving the expanded video data and the VBI signal data to generate output Y, U, V data in a term of an active video portion of a scan line.

摘要： PROBLEM TO BE SOLVED: To provide a signal processor capable of accurately detecting frame or field switching timing with a simple configuration even when the number of pieces of pixel data for one frame image or one field image obtained by sampling a frame image signal or field image signal on the basis of a reference signal of a prescribed frequency is a number that brings about a remainder in a division by the number of pieces of pixel data for one line.
SOLUTION: A memory control circuit 15 detects a trigger used for sampling in a clock signal CLK in each of line periods, detects first timing at which lines are switched on the basis of a discrete value showing the number of times of detecting the trigger, and holds the number of times which corresponds to the remainder and a discrete value from detecting the trigger till detecting the next trigger in a process of detecting the trigger about all lines in one frame or field.

摘要： PROBLEM TO BE SOLVED: To reduce jitters and to reduce the circuit scale as well by cumulatively increasing a unit addition to a frame, outputting sine wave shapes for which the cumulatively increased output is changed to a sine wave as analog sine waves and generating a clock phase synchronized with the analog sine wave output. SOLUTION: To a cumulative addition control circuit 2, a 4 fsc clock and frame pulses are inputted. The cumulative addition control circuit 2 outputs the unit addition 9 to a cumulative phase addition circuit 1 and the cumulative phase addition circuit 1 cumulatively adds the unit addition 9 and outputs the added value for sine wave generation 3. When the sine waves of 3.375 MHz are outputted from the sine wave generation 3, the output is turned to analog 3.375 MHz by D/A conversion 4. In a PLL 5, the 3.375 MHz is inputted and 27 MHz is outputted. Also, a unit amount to be added is temporarily changed, the frequency is finely changed, the need of a value exceeding 360 degrees is eliminated and the bit number of cumulative addition is reduced.

摘要： PROBLEM TO BE SOLVED: To suppress an area cross color that is unable to be suppressed at a receiver side by conducting two-dimensional contour along with plural straight lines that are drawn through positions of a color subcarrier frequency appearing a both left and right sides on the lateral axis around the origin, through positions of the color subcarrier frequency appearing discretely along with a straight line in parallel with the longitudinal axis and not through the origin. SOLUTION: A color image signal of the PAL system that is fed to an input terminal 11 and whose contour is to be corrected is divided into two, the one is fed to a 1st 2H delay circuit 12 and the signal that is outputted from this delay circuit and delayed by 2H is fed to a 2nd 2H delay circuit 13. The image signal that is outputted from the 2nd 2H delay circuit 13 and delayed by 4H is divided into two, and the one is fed to a 4th 2T delay circuit 15. Furthermore, the image signal that is outputted from the 1st 2H delay circuit 12 and delayed by 2H is fed to a 5th 1T delay circuit 16. The image signal that is outputted from a 3rd 2T delay circuit 14 and delayed by 2T is fed to a 1st gain adjustment circuit 17.
