摘要： The invention relates to a method for changing the image size of video images, in which a decimation of video image signals (V) by an integral decimation factor (MHD, MVD) is carried out, and the decimated video image signals are subsequently read into an image memory for buffering.In order to achieve better possibilities of adjusting the image reduction with a relatively low outlay and high image quality, a fine decimation of the video image signals (V) is additionally carried out before buffering by a fine decimation factor (SHS, SVS) which can be adjusted to non-integral values, and a total decimation factor (MH, MV) relevant to the decimation of the video image signals (V) is formed from the integral decimation factor (MHD, MVD) and the fine decimation factor (SHS, SVS).

摘要： In display apparatuses, particularly television receivers and monitors, a video picture can be inserted into a main picture (HB) from a first video signal (VS1), in which a second picture (ZB) from a second video signal (VS2) has a first picture format and is composed of picture lines (BZ) and filling lines (FZ). The picture lines (BZ) forming a sub-picture (UB) with the second picture format is adjoined by the filling lines (FZ) in the vertical picture direction. The second picture format of the sub-picture (UB) is determined and the determined second picture format is used for determining the filling lines (FZ). The picture lines (BZ) and a portion of the filling lines (FZ) are inserted as an insertion picture into the main picture (HB). Additional insertions (OSD) from an additional signal, which at least partly lie within the filling lines (FZ), is displaced into the sub-picture (UB).

摘要： A method for picture-in-picture insertion is described, which is distinguished in particular by the fact that the inset pictures are written to a memory device (2) in a circulating manner under continuously incremented write addresses, the first and last address of each written-in inset picture is stored, an overtake signal is formed by comparing the instantaneous address with the previously stored address, said signal indicating whether a previous address has been reached again and, consequently, the corresponding picture content has been overwritten, by evaluation of the overtake signal, the current or preceding segment is selected for read-out depending on whether or not overtaking took place before the start of the read-out, and the inset picture stored in the selected segment is read out with continuously incremented read addresses and is inserted into the main picture. A corresponding circuit arrangement is also described.

摘要： The invention relates to a method and a circuit arrangement for picture-in-picture insertion, in which a sequence of insertion pictures (Kj=K1,K2, . . . ) is read, with vertical decimation (VD≧1), into a memory device (S) and subsequently read out, the sequence of insertion pictures (Kj) read out is inserted into a sequence of main pictures (Hi=H1, H2, . . . ) and the memory device (S) is continuously overwritten by the insertion pictures.In order to prevent the occurrence of a seam during the insertion of the insertion pictures into the main pictures in a cost-effective manner and with a relatively low outlay on apparatus,the memory device (S) is subdivided into memory segments (X,Y,Z) which are continuously cyclically overwritten by the insertion pictures,the memory device (S) has a storage capacity of less than two insertion pictures, anda decision is made as to whether the currently written insertion picture (Kj) or the immediately preceding insertion picture (Kj−1) is read out.

摘要： An FFT device for performing a Fast Fourier Transform (FFT) of an operand vector of length N is described. The FFT device comprises a control unit, a coefficient unit, and a transformation unit. The control unit controls a sequence of transformation rounds, the transformation rounds including two or more FFT rounds and further including or not including a window round. The control unit also maintains configuration data indicating for each of said transformation rounds whether the respective transformation round is an FFT round, a window-FFT round, or a window round. The coefficient unit provides transformation data. The transformation unit is arranged to receive the transformation data and to perform the respective linear transformation on the basis of the transformation data. A method for performing a Fast Fourier Transform is described as well.

摘要： A data processing device and a method for performing second or next stage of an N point Fast Fourier Transform is suggested. The processing device comprises an input operand memory unit and an input buffer comprising a plurality of addressable memory cells arranged in lines and columns. Furthermore, the device comprises a number of radix-P operation units for producing output operands that are buffered in an output buffer. Input operands are read from the input operand memory unit and buffering into the input buffer. The input operands are stored and fetched from the input buffer according to a reordering scheme that allows efficient parallel processing of the operands by the butterflies and the buffering of subsequent input operands.

摘要： A method and a circuit arrangement for picture-in-picture insertion are described, in which, in order to prevent a write operation from being overtaken by a read operation and also to avoid the associated picture disturbances, a field is stored under an address which precedes a previous field by a number of N lines. A read address is then shifted to the same line of the older field in the event of a minimum distance to a write address being undershot.
