[0084]
The reproduction control unit 67 reproduces data stored in the storage 64 and supplies it to the decoder 68. When the compressed encrypted data and the decryption key are supplied from the reproduction control unit 67, the decryptor 68 decrypts the compressed encrypted data using the decryption key, and obtains the compressed official song data obtained as a result. The data decompression unit 69 is supplied. Further, when the sample audio is supplied from the reproduction control unit 67, the decoder 68 supplies the sample audio to the data decompression unit 69 as it is.
[0085]
When the official music data and sample audio supplied from the decoder 68 are compressed, the data decompression unit 69 decompresses the compressed official music data and sample audio, and the D / A converter 28 (FIG. 5). ). When the display data supplied from the selector 63 is compressed, the data decompression unit 70 decompresses the compressed display data and supplies the decompressed display data to the display device 30. The data expansion units 69 and 70 output the data as it is when the data supplied thereto is not compressed.
[0086]
Next, processing of the signal processing unit 27 of FIG. 9 will be described with reference to the flowchart of FIG.
[0087]
The main broadcast data from the ECC circuit 25 is supplied to the data expansion unit 61, and the data expansion unit 61 expands the main broadcast data and supplies it to the speaker 29 via the D / A converter 28. As a result, the main broadcast is output from the speaker 29.
[0088]
On the other hand, the data broadcast data from the ECC circuit 26 is supplied to the DMUX 62, where it is separated into bookmark data and data broadcast content. Further, in the DMUX 62, the data broadcasting content is separated into display data, sample audio, compressed / encrypted data, etc., and supplied to the selector 63 together with bookmark data.
[0089]
The selector 63 temporarily stores the data from the DMUX 63 in the memory 63 </ b> A, and thereafter sequentially updates the stored contents to data newly supplied from the DMUX 63. That is, in the memory 63A, for example, the bookmark data is updated for each data frame, and the data broadcasting content is updated, for example, every time one song broadcast by the main broadcast ends.
[0090]
Then, as shown in the flowchart of FIG. 10, first, in step S11, it is determined whether or not the operation unit 31 has been operated so as to output display data. If it is determined that such operation has been performed, In step S12, the selector 63 reads the display data stored in the memory 63A, supplies the display data to the display device 30 via the data decompression unit 70, and returns to step S11. Thereby, the display device 30 displays, for example, a jacket photo, an artist photo, a title, a singer name, and the like of the song currently being broadcast in the main broadcast.
[0091]
If it is determined in step S11 that the operation unit 31 is not operated to output display data, the process proceeds to step S13, and it is determined whether or not the operation unit 31 has been bookmarked. If it is determined in step S13 that the operation unit 31 has been bookmarked, that is, the user is interested in a song broadcast in the main broadcast (interesting), and the user adds a bookmark to the song. When the operation is performed, the process proceeds to step S14, and the selector 63 reads the bookmark data, sample sound, compressed encrypted data, and the like stored in the memory 63A, supplies them to the storage 64 for storage, and returns to step S11. In other words, the storage 64 stores (records) bookmark data, sample audio, compressed encrypted data, and the like for a song broadcast in the main broadcast when the operation unit 31 is bookmarked.
[0092]
Here, as described above, in the memory 63A, the content for data broadcasting is updated every time one song of the main broadcast is finished. If the operation unit 31 is bookmarked while the song is being broadcast, it is stored in the storage 64, but if the bookmark is not operated, it is deleted from the user terminal 3.
[0093]
On the other hand, if it is determined in step S13 that the operation unit 31 has not been bookmarked, the process proceeds to step S15, and it is determined whether or not the operation unit 31 has been operated to output sample audio. If it is determined in step S15 that the operation unit 31 has been operated to output sample audio, the process proceeds to step S16, and the reproduction control unit 67 reads the sample audio stored therein from the storage 64, and the decoder 68, the data decompression unit 69 and the D / A converter 28 are supplied to the speaker 29, and the process returns to step S11. Thereby, sample sound is output from the speaker 29.
[0094]
Here, even if the operation unit 31 is bookmarked and the compressed and encrypted data for a certain song is stored in the storage 64, the user forgets what the song is. It may end up. Therefore, in such a case, it is possible to recall what kind of music it was by reproducing and listening to the sample audio as described above.
[0095]
On the other hand, if it is determined in step S15 that the operation unit 31 has not been operated to output sample audio, the process proceeds to step S17 to determine whether or not the operation unit 31 has been downloaded to request the decryption key download. Determined. If it is determined in step S17 that the operation unit 31 has been downloaded, the process proceeds to step S18, and the download processing unit 65 performs a process of downloading a decryption key.
