Abstract: There is provided a signal processing device, including a partitioning section which partitions input data into a plurality of different partitioned data, and a plurality of signal processing sections which respectively process the plurality of different partitioned data. The signal processing sections each have a first processing section which performs a first data process targeting the partitioned data, and a communication section which transmits a first processing result by the first processing section to another of the signal processing sections, and receives a second processing result transmitted from another of the signal processing sections.

Abstract: A scanning line converting apparatus for converting the number of scanning lines of an output video signal into an arbitrary under of the scanning lines to form an output image signal. The scanning line converting apparatus includes a discriminator for discriminating an aspect ratio of a picture formed in accordance with a format of the input video signal and a display for displaying the discriminated aspect ratio. Since the discriminator discriminates the aspect ratio of the picture indicated by the input image signal and the display displays the discriminated aspect ratio, it is possible to adjust the monitor to display a picture of a proper aspect ratio based on the displayed aspect ratio.
