IMAGE DATA PROCESSING DEVICE AND METHOD

摘要

An image data processing method of processing MPEG-coded image data composed of data groups (Pack_V) each of which has an auxiliary recording area (AUX_V), begins with an I-picture or a P-picture, and includes a B-picture. When a recording medium contains a data group to be tag-recorded and a data group preceded by EditPack_V_h including a copy picture and/or stuffing bytes, the EditPack_V_h is separated and removed in a first tag recording, and a second tag recording is conducted. This eliminates unnecessary stuffing or a copy picture, thus preventing deterioration in image quality in a second tag recording.
