Abstract: A memory management control for a memory section is provided for use in a motion estimation or a compensation unit using a plurality of reference images. The plurality of reference images is stored in a memory section providing a memory area for each of the reference images. Each of the memory areas being adapted to store video data of one frame including a top field and a bottom field. The storage of video data in the memory section is controlled by a memory control section. A storage enable flag is assigned to each of the memory areas to enable the storage of image data of two successive fields in a single memory area.

Abstract: Provided is a data regeneration device, which is enabled to realize regeneration of no interruption at an effective/ineffective switching position of a band extending function, even in case the effectiveness/ineffectiveness of the band extending function is switched in a stream. The data regeneration device (2000) comprises an input frequency acquisition unit (2001) for analyzing header information (Hdr) to acquire an input frequency (FSin) or the frequency of basic data, an output frequency determination unit (2002) for performing a predetermined processing on the basis of the input frequency (FSin) to determine an output frequency (FSout) or the sampling frequency of a decoding frame (Fdata), and a decoding unit (2003) for decoding sample data with the input frequency (FSin), if an SBR function is effective in a frame to be decoded, to expand the band of the sampling frequency to the output frequency (FSout) by an SBR processing for the decoded result, thereby to sampling up, if the SBR function is ineffective, the decoded result in the input frequency (FSin) to the output frequency (FSout).

Abstract: A weighting factor mode determination unit (13) determines whether to code an interlaced picture in a field mode or a frame mode, based on a value of a flag "AFF" indicating whether or not to switch between the field mode and the frame mode on a block-by-block basis and notifies switches (14 and 15) and a multiplexing unit (106) of the determined mode. The switches (14 and 15) select either the field mode or the frame mode according to the notified mode. A field weighting factor coding unit (11) or a frame weighting factor coding unit (12) performs respectively the coding of respective weighting factors when the respective modes are selected.
