In order to be stored sequentially (S103).

When the broadcast signal reservation recording scheduling information is stored in the memory, the time is counted (S104). The counted time, that is, the current time and the start time of the broadcast programs for reserved recording stored in the memory are compared to determine whether they match each other. (S105).

As a result of the determination, when the current time coincides with the start time of one broadcast program among the plurality of reserved broadcast programs, the channel is tuned to receive the broadcast signal of the corresponding broadcast program (S106). Therefore, the broadcast signal of the corresponding broadcast program is received through the tuned frequency channel (S107).

Subsequently, it is determined whether the broadcast signal received through the tuned frequency channel is a digital broadcast signal or an analog broadcast signal (S108).

As a result of the determination, when the received broadcast signal is an analog broadcast signal, after converting the received analog broadcast signal into a digital signal (S109), the converted digital signal is encoded, if the received broadcast signal is a digital broadcast signal In this case, the received digital broadcast signal is encoded (S110) and sequentially stored in the second storage area of the memory (S111). Here, broadcast program name information may be used as a file name when storing broadcast data. That is, broadcast program name information is used as a file name in order to allow a user to easily select the playback of the reserved recorded broadcast data later.

As described above, the broadcast signal of one radio broadcast program is counted continuously during the prerecorded recording in the memory to compare the current time with the end time of the prerecorded broadcast program (S112).

As a result of the comparison, when the current time does not match the end time of the currently scheduled recording program, the broadcast signal of the corresponding broadcast program is continuously recorded in the memory until the end time of the broadcast program, and vice versa. If the time (current time) and the broadcast end time of the currently scheduled recording program match, the ongoing reservation recording process is terminated.

In addition, when the recording of the broadcast signals of all the broadcast programs reserved in the memory is checked by the start time and the end time of the broadcast program, the above process is repeatedly performed, and when the scheduled recording of all the reserved broadcast programs is completed (S113). This completes the entire scheduled recording process.

As described above, a method of reproducing the reserved recording broadcast signal according to the user's selection in the state of pre-recording all the broadcast signals of the radio broadcast program that the user intends to reserve recording will be described step by step with reference to FIG. .

6 is a flowchart illustrating an operation of a method of reproducing reserved recording broadcast data of an MP3 player according to the present invention.

As shown in FIG. 6, it is first determined whether a playback key for reproducing a reserved recording broadcast signal is input from a user (S201).

As a result of the determination, when a play key is input, all reserved recorded file names, that is, broadcast program name information stored in the second storage area of the memory are read and displayed on the display unit (S202). Here, the user may selectively delete the displayed reserved recording broadcast data.

It is determined whether one program to be played by the user is selected from the displayed broadcast program name information (S203).

As a result of the determination, if any one broadcast program is selected, the reserved recorded broadcast data corresponding to the corresponding broadcast program is read (S204), and the read broadcast data is encoded (S205).

The encoded broadcast data is D / A-converted to an analog signal so as to be reproduced through the speaker again (S206), and after a certain level amplification of the D / A-converted analog broadcast signal (S207), the amplified broadcast signal is transmitted through the speaker. It is to be reproduced (S208).

As a result, the broadcast signal reservation recording / reproducing apparatus and method of the MP3 player according to the present invention, in the MP3 player having a radio reception function, sets a scheduled recording schedule of the broadcast signal for the broadcast program desired by the user, Accordingly, the broadcast program start time and end time are checked to automatically reserve the broadcast signal of the desired broadcast program.
