PURPOSE: A simultaneous record/playback method of moving picture data is provided to maintain time shifting performance of HDD(Hard Disk Drive) active by controlling simultaneous record/playback program number. CONSTITUTION: A record task(100) records and requests a broadcasting program transmitted through a broadcasting network. A playback task(200) reads the recorded broadcasting program. A monitoring task(300) measures an expected deadline to a light and lead request of the record task(100) and the playback task(200) to detect number of request which is not processed within an appointed time, and requests to decrease number of the recorded SD(Standard Definition) program in case a deadline miss generates over an appointed threshold in a system. An HDD(500) records the SD program requested by the record task(100). An HDD interface unit(400) controls data transmission between the record task(100) or the playback task(200) and the HDD(500). |
