摘要： Provided is a function of providing a recordable time considering remaining memory capacity. To implement this function, an average reception rate of broadcasting data received for a predetermined time (e.g., several seconds) is calculated, and the recordable time is calculated using the calculated average reception rate and the remaining memory capacity. By doing this, even if the amount of broadcasting data to be recorded varies according to broadcasting programs, the amount of broadcasting data to be recorded can be predicted, and thereby, a user can efficiently record a desired broadcasting portion by actively determining whether the broadcasting is recorded.

摘要： An apparatus and method for storing digital broadcast data in a digital broadcast receiving terminal. If the digital broadcast receiving terminal enters a weak electric field strength region during reception of digital broadcast data, digital broadcast receiving terminal stops the process of receiving the digital broadcast data so as to check whether digital broadcast receiving terminal re-enters again into the strong electric field strength region. Then, if the digital broadcast receiving terminal re-enters the strong electric field region, the terminal shifts a TS value of a received digital broadcast data frame to the value obtained by adding a frame interval of the digital broadcast data frames to the TS value of the previous data frame that had been completely stored just before the digital broadcast receiving terminal entered the weak electric field strength region. Thus, the invention enables the digital broadcast receiving terminal to drop the digital broadcast data frames received during the weak electric field strength intervals so that it may smoothly and continuously play back the digital broadcast data frames received only during the strong electric field strength intervals.
