The controller 200 may control to directly play the music data stored in the memory 180.

2 illustrates an RDS data format for explaining the present invention.

The RDS data is composed of group units, and one group has four blocks, and each block has 26 bits (16 bits of information words + 10 bits of check words) and is transmitted in groups. Since the signal indicating the boundary between each group or each block is not inserted, the start of a group or block must be identified using an offset word in a check word. The information word contains information for providing various services, and the check word has information used for data error detection and correction. The offsetr includes information indicating a starting point of the block and the number of blocks within the group.

The RDS data format is divided into an A type group shown in FIG. 2A and a B type group shown in FIG. 2B. An area not used for the RDS data format (hereinafter, referred to as an 'ODA area') is provided differently to the A type group and the B type group. That is, in the type A group of FIG. 2A, the ODA area is provided in the second block-first area (5bit), the third block-second area (16bit), and the fourth block-third area (16bit). In the type B group of FIG. 2B, the ODA area is provided in the second block-the first area (5 bits) and the fourth block-the fourth area (16 bits).

The first regions in the A type group and the B type group are provided with the decode bits of 5 bits B0 to B4 as shown in FIG. 2C. Among them, B0 to B2 (3 bits) are used to decode data stored in the third region and the fourth region in the A type / B type group. The B2 bits are decoder control bits d0 to d3 (Decoder control bits), and B0 to B1 represent data addresses of the second area, the third area, and the fourth area. The B3 bit means that the data currently being received is the last data, and the B4 bit means that the data currently being received is the start data. For example, in FIG. 2C, when B2 bit is 'd0' and both B1 bit and B0 bit are '0', it means that data C0 to C15 or D0 to D15 linked to the data address are being received.

Referring to FIG. 2C, eight types of characters may be received in the type A group through regions of the third block and the fourth block, and thus, a total of 16 characters may be received. Referring to FIG. The type group is set to receive eight characters through the area of the fourth block. In addition, Arabic numerals 1 to 8 at the bottom of the C0 to C15 bits and the D0 to D15 bits in FIG. 2C indicate the order of receiving data.

On the other hand, title information is input to the areas provided in the second area and the third area of the A type group, and artist information is input to the fourth area of the B type group.

Next, a data storage device and a method thereof according to the present invention having the configuration as described above will be described in detail step by step.

In the present embodiment, a method of inputting music information to be stored (bookmark) and a method of automatically storing music on the air will be described with reference to the bookmarked music information. The music data storage device of the present embodiment should be a device capable of performing a Radio Data System (RDS) function.

First, a method of bookmarking music information in a storage device according to the present invention will be described with reference to FIG. 3.

If the music that the listener wants to store is being received while listening to the music broadcast signal, in step 100, the listener requests a bookmark by manipulating the bookmark selector 160 so that the music information can be automatically stored later. The bookmark selection signal generated by the bookmark selection unit 160 is transmitted to the controller 200, and the controller 200 receives the RDS data transmitted together with the music broadcast signal from the RDS decoder 150. . The song information includes at least one piece of information identifying music data, such as title and artist information. That is, when the RDS data of the music broadcast signal is transmitted by the A type group, reference is made to the title information input to the second and third areas. When the RDS data of the music broadcast signal is transmitted by the B type group, the artist information input to the fourth area. Will be referenced. Of course, the A type group and the B type group may be mixed and transmitted.

For example, when a song (title) information is received by RDS data having an A-type group, and the song information is 'spring, summer, autumn and winter', a total of eight characters can be received. Referring to the bits B0 to B4 and C0 to C15 shown in FIG. 2C, song information is received as shown in Table 1 below.

TABLE 1

In other words,

If B1 = 0, B0 = 0, then C15-C8 = spring, C7-C0 = F;

If B1 = 0, B0 = 1, C15 ~ C8 = name, C7 ~ C0 = go;

If B1 = 1, B0 = 0, then C15 ~ C8 = C7 ~ C0 = off;

If B1 = 1 and B0 = 1, then C15 ~ C8 = Wool:

Next, in step 101, the controller 200 checks whether the received song information ('spring, summer, autumn, and winter') is present in the bookmark list of the memory 180 by the method described above. The bookmark list includes music titles and artist information.

If the song information does not exist in the bookmark list, the controller 200 records the song (title) information in the bookmark list of the memory 180 in step 102. That is, since the song information is received, the received song information 'spring summer autumn winter' is recorded. However, the A type group can receive a total of 16 characters because there are two areas (2/3 areas) storing title information. Therefore, a title longer than the song information can be received. In addition, even when the artist information is received using the B type group, the process proceeds in the same manner as the song information reception. In addition, since the A-type group and the B-type group may be received in combination, in this case, title information and artist information may be recorded respectively.

Subsequently, in step 101, when the song information already exists in the bookmark list, the song information is not recorded. In this case, a notice message or voice message indicating that the song information is already recorded in the bookmark list is notified to the listener through the display unit 190 and / or a speaker.

Subsequently, a process of storing the bookmarked music information when it is broadcast will be described in detail with reference to FIG. 4. Here, as shown in [Table 1], the song information 'spring summer autumn winter' is stored and will be described as an example of storing when the music having the title is broadcast.

In operation 200, when the music having the title of 'Spring, Summer, Autumn and Winter' is received from the ODA region of the RDS data while receiving the broadcast signal, the controller 200 bookmarks the information having the song title stored in the memory 180. Check if it exists in the list.

As a result of the checking, if the current song information exists in the bookmark list, the controller 200 automatically stores music information regarding the song information. In this case, since the music information may be stored in the memory 180, in step 201, the controller 200 checks whether the current song information exists in the music data list previously stored in the memory 180. If the current song information is music data not stored in the memory 180, the controller 200 controls the recording / reproducing unit 170 to perform a recording operation.

Then, in step 202, the recording / reproducing unit 170 controls the music data separated from the music broadcasting signal received through the tuner unit 100 under the control of the control unit 200, that is, titled 'spring summer autumn winter'. Receives the music data having from the IF amplifier 110 and stores in the memory 180. In addition, the controller 200 records newly stored song information in a data list stored in the memory 180.

In step 203, the controller 200 checks whether recording of the music data is completed. As a result of the checking, when recording of the music data is completed, in step 204, the controller 200 deletes the current song information from the bookmark list.

If the current song information exists in the song list in step 201, the song information is deleted from the bookmark list by performing step 204.

As described above, in the present invention, when music data having song information that matches the bookmarked song information is broadcast using the bookmark function, the music data may be stored at the same time as the music data starts.

Although described with reference to the illustrated embodiment of the present invention as described above, this is merely exemplary, those skilled in the art to which the present invention pertains various modifications without departing from the spirit and scope of the present invention. It will be apparent that other embodiments may be modified and equivalent. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.

Music data storage device and method according to the present invention as described in detail above, it is possible to bookmark the song information to be stored by using the ODA area of the RDS data, and also the music matching the bookmarked song information in the broadcast When this flows out, the music can be stored at the same time as the start of the music, and thus the complete music can be stored without any loss, and there is no key operation for recording start and end, thereby improving user convenience.
