    摘要: A method for encoding an interlaced sequence of digital video data decomposes the interlaced video sequence (I) into first (F1) and second (F2) fields, performs digital filtering (SF1) to get lower frequency (L) and higher frequency (H) component signals of the first fields (F1), and uses spatio-temporal filtering (STF) and motion estimation (ME1) for generating base layer signals (P, MV1) being suitable for reconstruction of a progressive mode video sequence (V1,V2) in a receiver. Advantageously, both the spatio-temporal filter (STF) at the encoder, and the inverse process (STS) at the receiver, can perform scaling in spatial and temporal dimension. The second fields (F2) are used to generate enhancement signals (FF2, MV2), which enable a receiver to reproduce an interlaced video sequence of the full, or scaled, spatial and/or temporal resolution.
