Abstract
A data recording device for recording video data and/or audio data on a recording medium comprises a compression-encoding unit for compressing and encoding an inputted data stream, hierarchizing a variable data block, and blocking a plurality of generated lower-level data blocks as an upper-level data block, a data block temporary storage unit for temporality storing at least one upper-level data block generated in the compression-encoding unit and including n number (n is a given natural number) of lower-level data blocks; and a control unit for managing a size of the upper-level data block generated in the compression-encoding unit and controlling the compression-encoding unit to perform blocking of data blocks in such a way that the upper-level data block includes a plurality of lower-level data blocks to an extent that a size of the upper-level data block does not exceed a capacity of the data block temporary storage unit.
