Abstract:
1. An apparatus for storing digital broadcast data in a digital broadcast receiving terminal, comprising: a receiving state sensor for sensing the receiving state of the digital broadcast data; a digital broadcast receiver for receiving the digital broadcast data frame-by-frame; a memory part for storing at least one frame of the digital broadcast data, a first TS (Time Stamp) value of a data frame stored immediately prior to entering a weak electric field strength region, and a frame interval of the digital broadcast data; a TS extractor for extracting a first TS value of the data frame; a TS shifter for adding the frame interval to the first TS value of the data frame; and a control unit for dropping the digital broadcast data received in the weak electric field strength region when the digital broadcast receiving terminal enters the weak electric field strength region, determining whether the digital broadcast receiving terminal re-enters a strong electric field strength region, shifting a second TS value of a data frame received after entering the strong electric field strength region to a value obtained by adding the frame interval to the first TS value of the data frame so as to play back the data frames received during the strong electric field strength region continuously, and resuming the storing process when the digital broadcast receiving terminal enters the strong electric field strength region.
