  • Publication number: 20150339264
    Abstract: 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.

  • Patent number: 7061543
    Abstract: 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, and a decision is made as to whether the currently written insertion picture (Kj) or the immediately preceding insertion picture (Kj?1) is read out.

  • Patent number: 7002635
    Abstract: In the case of picture insertions, such as picture-in-picture, for example, fluctuations in the line duration are manifested in position displacements relative to the desired position of the inserted pictures. In order to prevent position displacements in the horizontal direction, it is provided that the insertion position is corrected in a manner dependent on a determined line duration. The method according to the invention is suitable in particular for picture-in-picture insertions in television receivers.

  • Patent number: 6975779
    Abstract: 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).

  • Patent number: 6950146
    Abstract: 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).

  • Patent number: 6873370
    Abstract: 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.

  • Patent number: 6870572
    Abstract: 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.

  • Patent number: 6762800
    Abstract: The circuit takes into account whether the image on a screen is too bright, whether more than one specific number of pixels have a luminance value that is greater than a given peak value and whether this condition is met in more than one specific number of lines in a picture and in more than one specific number of successive images with one such number of lines.

  • Patent number: 6285409
    Abstract: A method for producing a frame around a video image includes the step of placing subframes around a base frame. The subframes have an offset with respect to the base frame, in order to generate a plastic impression of the frame. The base frame and the subframes are produced from the same frame signal. A device for producing such a frame is also provided. The method and the device are in particular used in picture-in-picture systems.
