Apparatus and method for reproducing video segment for digital video cassette recorder

摘要

The method comprises the steps of: error-correction decoding (310) reproduced sync block data; determining whether there is any remaining error in the error-corrected sync block data, to select the error-corrected sync block data in the previous frame if an error remains, and select the error-corrected sync block data in the current frame if no error remains (320); saving the selected sync block data in a frame buffer (330); forming a segment (340) with selected sync blocks; determining whether the data is reproduced in variable-speed to process continuous data bits only between DCT blocks within a sync block when the data is reproduced in variable-speed, and process continuous data bits between DCT blocks within a sync block and between sync blocks within a video segment if not; variable-length decoding (350) the processed data; and performing an inverse discrete cosine transform (IDCT) operation for the variable-length decoded data. A decision regarding the continuity of data and the corresponding data processing are not needed, and thus the DVCR can minimize the refresh time of the data frame to be displayed.
