For this reason, by searching for text data, music data for the searched text data can be easily searched, and reading of desired music data becomes extremely easy.

  According to the text data synchronized recording apparatus of the present invention, the music data and the text data recorded in a separate recording apparatus are read, the desired music data is searched by referring to the read text data, and the next music is recorded. In order to facilitate data search, it is not necessary to newly add text data as a text tag to the searched music data and re-record the text tag and the music data together.

  A text data synchronized recording apparatus according to the present invention will be described below with reference to an embodiment.

  FIG. 1 is a block diagram showing a configuration of a broadcast receiver to which a text data synchronous recording apparatus according to an embodiment of the present invention is applied.

  A broadcast receiver to which a text data synchronous recording apparatus according to an embodiment of the present invention is applied receives program data that is multiplexed and transmitted, is decoded by the decoding apparatus 1, and is decoded. The data is recorded in the data recording device 2, the music data as program data and the text data corresponding to the music data are separated from the recorded data, and the separated music data is decoded by the music data decoding device 3. The decrypted music data is played back by the audio playback device 4 and the separated text data is displayed by the text data display processing device 5 and displayed on the display device 6.

  In the text data synchronous recording apparatus according to the embodiment of the present invention, the music data decoded by the music data decoding device 3 based on the recording instruction by the recording instruction device 9 and the display processing by the text data display processing device 5 are displayed. The recorded text data is synchronously recorded in the synchronous recording device 7.

  The synchronous recording device 7 can use a recording medium such as MD, CDR, and HDD. In the synchronous recording, music data is recorded on a recording track of the synchronous recording device 7 under the control of the recording control device 8 which receives the recording instruction from the recording instruction device 9, and a predetermined position of the recording track, for example, the recording Recording control is performed so that the text data corresponding to the music data is continuously recorded at the end of the track, and the music data and the text data corresponding to the music data are recorded in substantially synchronized manner.

  Further, by specifying the text data by the search instructing device 11 and instructing the search, the text data instructed to be searched is retrieved from the recorded contents of the synchronous recording device 7 under the control of the search control device 10, and the text data display Instead of the output from the processing device 5, the retrieved text data is displayed on the display device 6, the retrieved text data is confirmed from the display result, and the decoding recorded on the same recording track as the retrieved text data. The processed music data is read out, and voice reproduction processing is performed instead of the output data from the music data decoding apparatus.

  Next, recording to the synchronous recording device 7 will be described based on the flowchart of FIG.

  When the start of recording is instructed, recording of music data is started from the beginning of the new recording track (step S1), and then it is checked whether text data is received (step S2). If it is determined in step S2 that no text data has been received, recording is terminated.

  When it is determined in step S2 that the text data is received, it is checked whether the text data has been changed from the text data at the previous check (step S3).

  If it is determined in step S3 that the text data has not been changed from the previous check, it is checked whether or not the end of the recording track has been reached following step S3 (step S4). When it is determined that the recording by music data has reached the end of the recording track, the text data corresponding to the recorded music data is displayed at the end of the recording track. Subsequently, the recording is saved (step S5), and it is checked whether or not the recording instructing device 9 instructs to continue the recording (step S6). If it is determined in step S6 that a continuation instruction has been issued, the process is repeated from step S1.

  Therefore, when step S1 to step S6 to step S1 are repeated, audio data for the same text data is sequentially recorded on a plurality of recording tracks, and every time the recording track end portion is reached in this recording, the end of the recording track is reached. Text data corresponding to the music data is recorded (recorded) in the portion.

  When it is determined in the check in step S3 that the text data has been changed from the text data at the time of the previous check, this is a case where the text data corresponding to the music data has been changed. This is a case where data has been received. After step S3, the process proceeds to the end of the recording track immediately before (step S7), and the immediately preceding text data is recorded (recorded) at the end of the recording track. Is performed (step S8). Here, the music data recorded in step S7 is music data corresponding to the immediately preceding text data in step S3. The same recording track is advanced after the end of the music, and the immediately preceding text data is the text data at the end. Will be recorded.

  Following the execution of step S8, it is checked whether or not an instruction to continue recording is given (step S6). If it is determined in step S6 that a continuation instruction has been issued, the process is repeated from step S1. As described above, when step S1 to step S3, then step S7, step S8, step S6, and then step S1 are executed sequentially, the music data recorded on the new recording track in step S1 is the previous recording. The music is different from the music based on the music data recorded on the track, and the music data for the different music received next through the execution of steps S2 to S6 and S1 and the text data corresponding to the music data are recorded tracks. Will be recorded.

  As described above, the music data is recorded on the recording track of the synchronous recording device 7 and the text data corresponding to the music data is subsequently recorded at a predetermined position of the recording track, for example, the end portion. The text data corresponding to the music data is recorded substantially synchronously.

  Further, when desired music data is read from the synchronous recording device 7 recorded as described above, a search is instructed by designating text data by the search instructing device 10, and the text data instructed to search is the search control device 10. Under the control of the above, the recorded contents of the synchronous recording device 7 are searched, the searched text data are displayed on the display device 6, the search text data is confirmed from the display result, and is the same as the searched text data. The decrypted music data recorded on the recording track is read out and the sound is reproduced.

  Here, when there are a plurality of types of text data corresponding to the music data, one of the plurality of data may be selected, and the plurality of text data are concatenated and recorded as one text data. You may do it. Further, the case where music data and text data corresponding to the music data are recorded as a pair for each recording track is exemplified, but the text corresponding to the music data is recorded on the recording track of the music data when one music is finished. Data may be recorded. In such a case, the text data may be searched and the music data recorded from the next recording track may be the desired music data following the text data immediately before the searched text data.

  Furthermore, the recording track may be divided every time different text data is received. It is also possible to specify text data and not delimit the recording tracks unless text data different from the designated text data is received.

  When text data synchronous recording according to the present invention is not selected, normal recording is performed.
