Abstract
Code words, which correspond to orthogonal-transform-resultant coefficients having order numbers equal to or higher than an order number “n+1”, are deleted from code words composing each 1-intra-frame segment of an input digital picture signal to generate special picture data with a frame period NS on the basis of the input digital picture signal. Estimation is made as to a code amount CF(nmin) of special picture data generated by deleting code words, which correspond to orthogonal-transform-resultant coefficients having order numbers equal to or higher than an order number “nmin+1”, from code words composing a 1-intra-frame segment of the input digital picture signal, where “nmin” denotes a lower limit of an order number “n”. The frame period NS of the special picture data and a target code amount C are decided so that the estimated code amount CF(nmin) will be equal to or smaller than the target code amount C. The input digital picture signal is recorded on a recording medium. The special picture data is recorded on predetermined positions in the recording medium.
