MPEG conversion system for converting digital video signals, MPEG conversion apparatus and recording medium memorizing a software of the MPEG conversion system

摘要

An MPEG conversion system for converting digital video signals transferred from a digital video camera to a personal computer into MPEG data and saving into a data storage apparatus is disclosed. When an intermediate working area for the conversion is entirely occupied, the camera is stopped. After the position of the tape at this time is read and memorized, the tape is rewound to a prescribed position. When the working area has a vacancy, the camera is started and, when the tape exactly reaches the memorized position, the writing of the digital video signals into the working area is resumed. The digital video signals are then converted into MPEG data. Images of a high quality are produced without frame drops or excessive occupation of the disk space even when a low speed personal computer is used. MPEG data can be obtained automatically by leaving the apparatus standing without manipulation for a prescribed time.
