Thus, counting means for counting the number of tracks to which message information is added and the number of tracks to which message information is not added, and counting by the counting means. If the number of tracks to which message information is added is equal to or greater than the number of tracks to which message information is not added, each track on which signal data encoded by the second encoding method is recorded is added. When message information is added to management data corresponding to a track to which no message information is added among the corresponding management data, and the number of tracks to which the message information is added is smaller than the number of tracks to which no message information is added. Data editing means for deleting the message information from the management data corresponding to the track to which the message information is added.

[0008] The counting means is based on flag information included in the data indicating the recording mode in the management data.
It is desirable to specify the track on which the recording data encoded by the second encoding method is recorded.

A recording area is allocated. The management data area of the recording / reproducing carrier 10 includes management data such as TOC (Table Of Contents) and U-TOC.
(User's-TOC) is recorded.

FIG. 2 shows the U-TOC of the recording / reproducing carrier 10.
FIG. 3 is a diagram illustrating a configuration of management data recorded in an area sector 0. As shown, the management data recorded in the U-TOC area sector 0 is from the 0th line to the 58th line.
It is composed of 588 × 4 bytes of data up to the seventh line, and includes information for managing audio signal data recorded in the program area. In FIG. 2, "
The numerical value indicated by adding "h" is a numerical value in so-called hexadecimal notation.

The P-TNOn (n; 1 to 25) provided in the twelfth to seventy-fifth rows of the management data shown in FIG.

FIG. 3 shows the U-TOC of the recording / reproducing carrier 10.
FIG. 3 is a diagram illustrating a configuration of management data recorded in an area sector 1. The management data recorded in the U-TOC area sector 1 is the same as the management data recorded in the U-TOC area sector 0, from the 0th line to the 58th line.
It consists of 588 x 4 bytes of data up to the seventh line. FIG.
Are the character information indicating the name of the disc (Disc Name) of the recording / reproducing carrier 10 and the character indicating the track name (Track Name) for each track of the audio signal data. It contains title information consisting of information.

That is, the twelfth of the management data shown in FIG.
The table pointer P-TNAm (m; 1 to 255) provided from the line to the 75th line specifies the head byte position of the parts table in which the character information indicating the disc name and the track name is recorded.

From the 78th line of the management data shown in FIG. 3, character information such as an ASCII code indicating a disc name or a track name, for example, an album title or a song title is recorded. By specifying the parts table in which such character information is recorded by the table pointer P-TNAM, the system controller 18 can determine which track corresponds to the character information. For example, in the parts table specified by the table pointer P-TNA1, the title of the first song (track number is "1") can be recorded.

The editing apparatus 100 having the above configuration will be described below.
Will be described. In the following, as an example, predetermined predetermined character information “LP:” is associated with audio signal data encoded according to the ATRAC3 method, which is an encoding method of a new standard, as message information. And is managed by management data.

Here, on the recording / reproducing carrier 10, title information for notifying the user of the recorded content is recorded in association with each track of the audio signal data to which the recording position information is given by the management data. This title information is recorded, for example, in the U-TOC area sector 1 of the recording / reproducing carrier 10 and displayed on the display unit 20 when reproducing the audio signal data.

When recording the audio signal data encoded by the ATRAC3 system, which is a new standard encoding method, the default character information "LP:" is the first three characters in the title information corresponding to the audio signal data. It is added as character information of the character.

The recording apparatus capable of recording audio signal data encoded by the encoding method of the new standard on the recording / reproducing carrier 10 does not add an operation mode for adding such predetermined character information in accordance with an instruction from a user. It is conceivable that any one of the operation modes can be set. In addition, using a recording device that does not have a function of adding the predetermined character information as title information, the audio signal data encoded by the encoding method of the new standard is used to record and reproduce the carrier signal.
Recording to 0 is conceivable. In such a case, on the recording / reproducing carrier 10, title information to which predetermined character information is added is recorded among a plurality of tracks on which audio signal data encoded by a new standard encoding method is recorded. And title information to which title information to which default character information is not added may be mixed.

Here, the recording device capable of recording the audio signal data encoded by the encoding method of the new standard on the recording / reproducing carrier 10 executes, for example, the processing shown in the flowchart of FIG.

That is, the recording apparatus determines whether or not recording of audio signal data encoded by a new standard encoding method has been instructed by an instruction from a user (step S1).

When the recording apparatus determines that recording of the audio signal data encoded by the encoding method of the new standard is not instructed (NO in step S1), the processing shown in the flowchart of FIG. 4 ends. On the other hand, the recording device
When it is determined that recording of audio signal data encoded by the encoding method of the new standard has been instructed (YES in step S1), it is determined whether an operation mode for forcibly adding default character information is set. (Step S
2). The operation mode of the recording apparatus is set in advance in accordance with, for example, instruction information input in response to a user's key operation or the like.

When the recording device determines that the operation mode for forcibly adding the default character information is set (YES in step S2), the first three characters of the title information corresponding to the track on which the audio signal data is to be recorded are set. In addition, "L
P: "is added (step S
3). On the other hand, when the recording apparatus determines that the operation mode for forcibly adding the default character information is not set (NO in step S2), the operation mode for automatically adding the default character information (automatic addition mode) is set. It is determined whether or not the setting has been made (step S4).

When the recording apparatus determines that the automatic addition mode is not set (NO in step S4), the processing shown in the flowchart of FIG. 4 ends. On the other hand, when the recording apparatus determines that the automatic addition mode is set (YES in step S4), it determines whether the setting in the automatic addition mode is to add the default character information (step S4). S5).

When the recording apparatus determines that the setting in the automatic addition mode does not add the predetermined character information (NO in step S5), it ends the process shown in the flowchart of FIG. On the other hand, when the recording apparatus determines that the setting in the automatic addition mode is to add the default character information (YES in step S5), the processing proceeds to step S3, and the first three characters of the title information are set to "L".
P: "is added to the default character information. In this manner, the recording apparatus can add the default character information to the title information according to the user's setting.

It is desirable that the editing apparatus 100 according to the embodiment of the present invention has a function as a recording apparatus for executing the processing shown in the flowchart of FIG. It is not excluded.

The recording / reproducing carrier 10 on which the audio signal data encoded by the encoding method according to the new standard is recorded is converted by the editing apparatus 100 into a spindle motor 11.
When the system controller 18 is set so as to be able to perform the rotational drive by the system controller 18, the encoding method determination unit 22 executes the processing shown in the flowchart of FIG. 5. At this time, the system controller 18 executes the operation program stored in the memory 21 and starts processing by the encoding method determination unit 22.

When the processing shown in the flow chart of FIG. 5 is started, the encoding method determining section 22 sends a command to the digital signal processing circuit 17 and is recorded on the recording / reproducing carrier 10 such as TOC or U-TOC. An instruction to read the management data is issued (step S10).

The digital signal processing circuit 17 which has received a command from the encoding method determining unit 22 controls the operations of the spindle motor 11, the optical pickup 12, the feed motor 13 and the like to read out management data. The data read from the management data area of the recording / reproducing carrier 10 is stored in the memory 21 and is held in a state where it can be analyzed by the encoding method determining unit 22.

The encoding method determination unit 22 sets the variables X and Y for counting the number of tracks where the predetermined character information is added to the title information and the number of tracks where the predetermined character information is not added to “0”. An initialization process such as (Step S11).

The encoding method determining unit 22 specifies the minimum TNO based on the management data read from the U-TOC area sector 0 of the recording / reproducing carrier 10 and recorded in the memory 21 and assigns the minimum TNO to the variable checkTNO. Substitute (Step S
12). Here, the encoding method determination unit 22 determines the pointer First TNO and the pointer L included in the management data shown in FIG.
By obtaining the ast TNO, the minimum track number (minimum TNO) and the maximum track number (maximum TNO) of the audio signal data recorded on the recording / reproducing carrier 10 can be specified.

Thereafter, the encoding method determining unit 22 determines whether the variable
It is determined whether or not the audio signal data recorded on the track specified by checkTNO has been encoded by a new standard encoding method such as the ATRAC3 method (step S13). More specifically, the encoding method determination unit 22 searches the management data read from the U-TOC area sector 0 and stored in the memory 21 and reads the parts table of the track specified by the variable checkTNO. , The encoding method of the audio signal data is specified. For example, the encoding method determination unit 22
When the 1-bit flag information included in the Track Mode in the management data shown in FIG. 2 is “0”, it is determined that the audio signal data has been encoded by the encoding method of the new standard. In addition, the encoding method determination unit 22 uses the Track Mode
When the 1-bit flag information included in the audio signal data is "1", it is determined that the audio signal data is encoded by the encoding method of the old standard.

If the encoding method determination unit 22 determines that the encoding method is that of the old standard, that is, that it is not the encoding method of the new standard (NO in step S13), the process proceeds to step S17 described later.

On the other hand, if the encoding method determining section 22 determines that the encoding method is a new standard encoding method (Y in step S13).
ES), it is determined whether or not the default character information “LP:” is added to the title information recorded corresponding to the track specified by the variable checkTNO (step S14). More specifically, the encoding method determination unit 22
Is the U-TOC area sector 1 of the recording / reproducing carrier 10
And retrieves the management data stored in the memory 21 and reads the parts table corresponding to the track specified by the variable checkTNO. At this time, the encoding method determination unit 22 determines “L” at the first three characters of the title information.
P: "character information is detected. Encoding method determination unit 2
No. 2 determines that the default character information is added when "LP:" is detected. Also, the encoding method determination unit 2
No. 2 determines that the default character information is not added when “LP:” cannot be detected.

When the encoding method determining section 22 determines that the default character information is added (YE in step S14).
S), increment the variable X by 1 (step S)
15). On the other hand, when determining that the default character information is not added (NO in step S14), the encoding method determination unit 22 increments the variable Y by 1 (step S16). In this way, the encoding method determination unit 22 counts the number of tracks on which title information to which default character information is added and the number of tracks on which title information to which default character information is not added are recorded.

Thereafter, the coding method determining unit 22 advances the process to step S17, increments the variable checkTNO by 1 (step S17), and sets the variable checkTNO to the maximum TN.
It is determined whether or not O has been exceeded (step S18).

If the encoding method determination section 22 determines that the maximum TNO has not been exceeded (NO in step S18), the process returns to step S13, and the default character information is added to the title information corresponding to the next track. The processing is continued to determine whether or not is added. On the other hand, when the encoding method determination unit 22 determines that the maximum TNO has been exceeded (YES in step S18), the processing illustrated in the flowchart of FIG. 5 ends. By executing such processing, the variables X and Y hold the number of tracks in which the default character information is added to the title information and the number of tracks in which the default character information is not added, respectively.

After that, the editing device 100 operates the operation unit 19
According to the instruction information input in response to the user's key operation or the like, or automatically when the system controller 18 detects the end of the processing shown in the flowchart of FIG.
The unified editing process shown in the flowchart of FIG. 6 is executed.
At this time, the system controller 18 executes the operation program stored in the memory 21 and starts the unified editing process shown in the flowchart of FIG.

When the unified editing process is started, the system controller 18 determines whether or not an automatic addition mode for automatically adding default character information has been set (step S20). The operation mode of the editing device 100 is set in advance according to, for example, instruction information input by the operation unit 19 in response to a key operation or the like by a user.

When the system controller 18 determines that the automatic addition mode is not set (step S20)
NO), the unified editing process shown in the flowchart of FIG. 6 ends. On the other hand, when the system controller 18 determines that the automatic addition mode is set (step S
20 (YES), it is determined whether both the variables X and Y are not “0” (step S21). Here, when both the variables X and Y are “0”, the audio signal data encoded by the encoding method of the new standard is not recorded on the recording / reproducing carrier 10, so that the title information is edited. do not have to. When either one of the variables X and Y is “0”, the title information corresponding to each track recording the audio signal data encoded by the encoding method of the new standard is the default. The information is unified to either title information to which character information is added or title information to which no character information is added. Therefore, in this case also, there is no need to edit the title information.

If the system controller 18 determines that at least one of the variables X and Y is "0" (NO in step S21), the system controller 18 ends the unified editing process shown in the flowchart of FIG. On the other hand, the system controller 18 determines that the variables X and Y are both “0”.

When the system controller 18 determines that the variable X is smaller than the variable Y (N in step S22)
O), the character information deletion process shown in the flowchart of FIG. 7 is executed (step S23). On the other hand, if the system controller 18 determines that the variable X is greater than or equal to the variable Y (YES in step S22), it executes the character information adding process shown in the flowchart of FIG. 8 (step S2).
4). Thereby, for example, ATRAC3 system,
When the audio signal data encoded by the encoding method of the new standard is recorded on a plurality of tracks on the recording / reproducing carrier 10, the title information corresponding to each track is replaced with title information to which predetermined character information is added. , And unified title information.
