摘要
A method and apparatus for encoding/decoding a multi-layer interlaced video signal having macroblocks coded in an interlaced manner is provided. The method includes determining whether a pair of macroblocks of a current layer are of a frame type and a corresponding pair of macroblocks of a lower layer are of a field type; and predicting and encoding a macroblock of the current layer by interpolating information of the top or bottom field of a corresponding macroblock of the lower layer, if the pair of the macroblocks of the current layer are of the frame type and the corresponding pair of the macroblocks of the lower layer are of the field type, and the top and bottom fields of the corresponding pair of the macroblocks of the lower layer have been coded in different prediction modes.
