2 is a flowchart showing in detail the operation of the music album generating method in the optical recording and reproducing apparatus according to the present invention.

First, the microcomputer 12 determines whether the music album generation signal according to the user's operation is input from the key input unit 8 (S10), and when the music album generation signal according to the user's operation is input, the current optical record reproduction is performed. It is determined whether the device is in the time shift and disc recording mode (S20).

If the current optical recording and reproducing apparatus is not in the time shift and disc recording mode, the microcomputer 12 notifies the user that the music album generating function selected by the user is not possible and ends (S30).

As a result of the above-described determination in step S20, if the current optical recording / reproducing apparatus is in the time shift and disc recording mode, the microcomputer 12 outputs a control command to the audio decoder unit 6 and selects the audio data tuned to the tuner unit 2. The audio frequency extraction unit 8 can be driven by modifying the output path such that the output is output to the MPEG processing unit 14 through the audio frequency extraction unit 8 (S40).

Then, the audio frequency extraction unit 8 extracts the frequency component at the time of the music album generation selection of the broadcast program tuned to the tuner 2 and outputs the frequency component to the MPEG processor 14 (S50).

The audio frequency extractor 8 extracts a frequency component of audio data when a predetermined time interval (for example, 3 seconds or longer) elapses after the music album generation selection time point. 14) (S60).

The MPEG processing unit 14 compares the frequency components at the time of the music album generation and selection selected at step S50 and S60 with the frequency components after a predetermined time interval under the control of the microcomputer 12 (S70). It is determined whether the predetermined number or more (for example, five or more / less) can be determined (S80). At this time, in addition to determining how many or more identical frequency components exist, the MPEG processor 14 may use a method of determining whether a predetermined time (for example, five minutes) has elapsed. This is because music typically does not last more than five minutes in a broadcast program.

As a result of the determination, if the same frequency component is present in a predetermined number or more, the MPEG processor 14 considers that the music is not finished and continuously stores the music information and repeats the operation after step S60 (S90).

However, if the same frequency component does not exist more than a predetermined number as a result of the above-described determination in step S80, the MPEG processor 14 regards the music as the end point of the music and stops storing (S100). Music information on the broadcast program currently received and processed until the end of the music is stored in the storage unit 18 (S110).

After storing music information from a music album generation selection time point to a music end time point, the MPEG processing unit 14 stores the audio data stored in the nonvolatile memory 24 according to a time shift function under the control of the microcomputer 12. Search for (S120).

In the audio frequency extracting section 8, the audio data stored in the nonvolatile memory 24 has audio data at a predetermined time interval (for example, 3 seconds or longer) before the music album generation time. Extract the frequency component with respect to the output to the MPEG processor (14) (S130).

The MPEG processor 14 compares the frequency components of the music album generation time selected at step S50 and S130 with the frequency components before a predetermined time interval under the control of the microcomputer 12 (S140). It is determined whether the component is a predetermined number or more (S150). In this case, the MPEG processor 14 may use a method for determining whether a predetermined time has elapsed, in addition to determining how many or more identical frequency components exist as described above.

As a result of the determination, if the same frequency component is present in a predetermined number or more, the MPEG processor 14 considers that the music is not finished and continuously stores the music information and repeats the operation after step S130 (S160).

However, if the same frequency component does not exist more than a predetermined number as a result of the above-described determination in step S150, the MPEG processor 14 considers the music start time and stops storing (S170). Music information on the broadcast program stored in the nonvolatile memory 24 until the music start time is stored in the storage unit 18 (S180).

Subsequently, the MPEG processing unit 14 controls the music information from the music album creation time point to the end time of the music album and the music information from the music album generation time point to the music start point as one music file under the control of the microcomputer 12. The combination is generated (S190), and the generated one music file is stored in the storage unit 18 (S200).

Thus, users who use the optical recording and playback apparatus, although not the same high quality as the record, can start storing while watching a broadcast program without missing the separated music at the beginning and end to implement their own meaningful music album. Will be.

Herein, while the present invention has been described with reference to the preferred embodiments, those skilled in the art will variously modify the present invention without departing from the spirit and scope of the invention as set forth in the claims below. And can be changed.

As described above, according to the apparatus and generation method of the music album in the optical recording and playback apparatus of the present invention, even if a user who views a music channel or a drama selects a music album generation in the course of a particular music, the entire part of the music By automatically tracking and storing the file as a file, users who use the optical recording and playback device can conveniently play and listen to favorite music used for broadcasting anytime and anywhere. This has the effect of creating an advanced image.
