DIGITAL RECORDING/REPRODUCING DEVICE FOR SUPPLYING TIME SHIFT FUNCTION AND METHOD THEREFOR, CAPABLE OF REPRODUCING RECORDED DATA WHILE RECORDING THE DATA EVEN THOUGH THE DATA IS RECORDED ON DATA STORAGE MEDIUM EASILY INCAPABLE OF REALIZING TIME SHIFT FUNCTION

摘要

PURPOSE: A digital recording/reproducing device for supplying a time shift function is provided to reproduce recorded data while recording the data even though the data is recorded on a data storage medium easily incapable of realizing a time shift function, thereby supplying a time shift function to the data. CONSTITUTION: A controller(130) receives compressed video data from a video data encoder(110), records or deletes video data compressed on the first data storage medium(150) and the second data storage medium(200), or reads data recorded on the first data storage medium(150) and the second data storage medium(200), and outputs the read data to a video data decoder(170). The first data storage medium(150) has a sufficiently quick data access time and a data read/write feature to realize a time shift function. The video data decoder(170) receives the data recorded on the first and second data storage media(150,200) from the controller(130), decodes the data, and outputs the decoded data to a display device.
