Picture signals are encoded so that one of a frame-based orthogonal transformation or a field-based orthogonal transformation is selected as a function of frame-based orthogonal-transformation coefficients and field-based orthogonal transformation coefficients. The coefficients representing the smallest quantity of data are selected and encoded for transmission. Alternatively, a picture signal is encoded so that one of intra-frame coding and inter-frame coding, as well as either a frame-based or field-based orthogonal transformation, are selected as a function of the respective orthogonal transformation coefficients.
