    摘要: Device for splitting a digital interlaced television signal into components in which interlaced frames are applied to a vertical low-pass filter (6). To prevent motion artefacts in the spatial signal thus obtained, the interlaced frame is also applied to a vertical high-pass filter (8). This vertical high-pass filter supplies a motion auxiliary signal which may have a small vertical bandwidth. When combining the spatial signal and the motion auxiliary signal, noticeable motion artefacts do not occur in the interlaced frame. The device may be used for deriving a standard television signal from a high-definition television (HDTV) signal and for compatible transmission of HDTV signals.

    摘要: In a motion vector estimation method, a block-based motion vector estimation process (BME) that involves comparing a plurality of candidate vectors is carried out to determine block-based motion vectors, at least a most frequently occurring block-based motion vector (MFMV) is determined, a global motion vector estimation process (GME) using at least the most frequently occurring block-based motion vector (MFMV) is carried out to obtain a global motion vector (GMV), and the global motion vector (GMV) is applied as a candidate vector to the block-based motion vector estimation process (BME).
