Abstract: A video signal processing apparatus which is provided for a digital video decoder and can automatically and properly adjust a fluctuation of the number of sampling data of digital composite video signals includes: an adjusting circuit which performs a partial adding/deleting process to the video signals so as to correct the fluctuation in number of sampling data constructing the digital composite video signals supplied to the decoder; and a discriminating circuit which compares the number of sampling data of each video signal and the preset reference number of sampling data and outputs an operation signal for the adding/deleting process to the adjusting circuit when a difference between them as a comparison result lies within a predetermined adjusting range.

Abstract: A SECAM video signal is decoded by selecting different combinations of chrominance signals according to the luminance difference between the current line and the preceding line. The chrominance signals from the current line and the preceding line are selected when this difference is smaller than a threshold. The chrominance signals from the current line and the next line are selected when the difference is greater than the threshold. The average value of the chrominance signals in the preceding and following lines may be calculated and selected in place of the chrominance signal from the preceding line.

Abstract: Coaxial resonators serving as input and output stages are arranged on a dielectric substrate having input and output coupling strip lines and a grounding electrode formed in the same plane as the strip lines and surrounding the strip lines. The substrate is shaped substantially in conformity with the bottom contour of the resonators as arranged on the substrate.
