摘要： An encoding circuit (1) encodes an input image. A thinning-out decision unit (2) determines whether or not a picture needs to be thinned out. A dummy picture storage device (4) stores a dummy picture. A dummy picture is encoded data in which all the blocks refer to the same picture, motion vectors of all the blocks are zero, and none of the blocks has prediction residual information. A reference picture selection unit (5) selects a reference picture from among a plurality of referenceable pictures. A header generating unit (7) generates a header to be added to a dummy picture. In the header, the selected reference picture is assigned to an index specifying a reference picture for the dummy picture.

摘要： The apparatus includes: orthogonal transforming means for orthogonally transforming an input video signal for each element block, quantizing means for quantizing each obtained transformation coefficient using a quantization parameter; coding means for coding the quantization parameter; decoded picture generating means for generating a reference picture signal for a motion compensation prediction from the quantized results of the quantizing means; filtering means for filtering the obtained reference picture signal at a strength corresponding to the quantization parameter when a non-zero effective transformation coefficient is present with respect to the element block; and controlling means for controlling at least anyone of transformation coefficients to be not zero, when all of the transformation coefficients are zero. This allows, even when all of the quantized results of the transformation coefficients of the element blocks are zero, coding of quantization parameter of current element block and control of filtering strength.

摘要： An encoding apparatus having a direct mode as a prediction mode, when a pixel with opposite parity from a top field to a bottom field, for example, is referred to for obtaining a reference vector in the direct mode, performs correction by adding or subtracting a value corresponding to a half pixel to or from a value of the obtained reference vector. The encoding apparatus, when a pixel with opposite parity is referred to for obtaining a first and a second direct vector by temporally scaling the corrected reference vector, performs correction by adding or subtracting a value corresponding to a half pixel to or from values of the obtained direct vectors.
