摘要： A pattern analyzing portion analyzes a pattern of a detected repeat field and determines whether or not the pattern of the repeat field is continuous. An inverse pull-down controlling portion controls a memory to read video data in such a manner that the repeat field detected by a comparator is removed from input video data in a period that the pattern of the repeat field is continuous. The inverse pull-down controlling portion controls the memory to read video data in such a manner that a repeat field detected by the comparator is not removed from the input video data in a period that the pattern of the repeat field is discontinuous. In other words, an inverse 2:3 pull-down process is controlled corresponding to the continuity of a pattern of a repeat field. In addition, it is determined whether an input original material is a progressive-scanned video material or an interlace-scanned video material corresponding to the continuity of the pattern of the repetitive material.

摘要： A video data compression apparatus with which compressed video data of suitable amounts of data can be produced and in addition the time required for processing is short. An encoder control unit performs a preprocessing for compression and coding and, at the same time, produces a flatness and an intra AC as parameters indicating the difficulty of the pattern of pictures to be compressed to I pictures. A motion detector calculates a predictive error amount (ME residual) of the motion prediction. An FIFO memory delays each picture of the input video data. A host computer approximates a real difficulty data Dj indicating the difficulty of the pattern of each picture by the ME residual, flatness, and intra AC and further calculates the target amount of data Tj of the compressed video data from the approximated real difficulty data Dj. The encoder performs the compression and coding so that the amount of data of the compressed video data becomes substantially the target amount of data Tj.
