Abstract
A rate control for a VCR or the like records digitized image data by compression coding technologies so that the code amount of the compression coded data becomes a predetermined code amount or less. Even in the case where an interleave is performed among a plurality of blocks, the prediction error of the code amount after the interleave can be reduced and the rate control can be precisely performed by quantizing so that the same quantization table is assigned to each of the interleaved blocks in pre-scanning in the pre-stage of an interleave memory.
