Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for receiving and recording digital music information, comprising a digital broadcast receiving and recording terminal and a portable information storage medium.
In particular, the present invention relates to a digital broadcast receiving and recording system for realizing sale of digital music information using broadcasting.

[0002]

2. Description of the Related Art One type of music content sales is CD rental. With a CD rental, you can record and enjoy only your favorite songs at a lower cost than purchasing the CD itself. In recent years, with the spread of mini discs (hereinafter referred to as MD), CD rental shops
The style of borrowing and digitally recording on MD has been established. However, the disadvantage of CD rentals is that you have to rent a CD to a rental shop or return it.

[0003] Another method for recording music content is broadcast recording. By recording what is broadcasted on radio or television, users have the advantage that they can record freely for free and do not have to borrow or return them as compared to CD rentals. On the other hand, conventional radios and televisions are analog broadcasts, and therefore have disadvantages such as poor sound quality and the need for a user to perform a recording operation while confirming the beginning and end of a song by ear when recording.

[0004] However, in recent years, digital broadcasting has started and is becoming popular. These digital broadcasts are encrypted, and in order to view them, it is necessary to purchase a receiving terminal called IRD and make a viewing contract with a broadcaster. The contract information is stored in a portable information storage medium such as an IC card, and the receiving terminal permits viewing based on the contract information in the portable information storage medium. The digital broadcast viewing contract includes a channel unit, a program unit, and the like. If a contract is made on a channel-by-channel basis, a fee is collected periodically regardless of whether or not the content is viewed. In the program unit, the fee is charged only when the user watches the program, and the fee information is stored in the portable information storage medium. The receiving terminal periodically transmits the billing information to the user management center through the telephone line. Some of these digital broadcasts broadcast music,
Digital recording is possible.

On the other hand, since digital information can be copied without deterioration, it is necessary to prevent illegal digital copying.

[0006] Japanese Patent Application Laid-Open No. 8-186667 describes a system for encrypting and transmitting music or video content requested by a user through a bidirectional digital network. In this system, the content transmitted from the information center is recorded in an encrypted state on the terminal, and when the user requests viewing of the recorded content, the terminal is recorded on a portable information storage medium. Only when the viewing is permitted based on the contract information, the decryption is performed and the viewing is performed. As described above, JP-A-8-186667 discloses that
We provide a system that enables digital recording while preventing unauthorized digital copying.

As a standard for restricting digital copying performed by connecting digital AV equipment, a serial copy management system is described as described on page 444 of the Nikkei BP Digital Encyclopedia (1998 edition). (Serial Cop
y Management System (hereinafter referred to as SCMS). SCMS
Thus, digital copying performed by connecting digital AV equipment can be limited to the first generation. For example, from CD to M
Digital copy (1st generation copy) can be performed to D, but digital copy (MD
Generation copy) cannot be performed.

[0008]

Generally, video contents are viewed in a limited place such as indoors, whereas music contents are not only indoors but also while walking, as represented by a walkman. The style of playing and listening casually in various places, such as in a car or in a car, has been established. However, in the system described in Japanese Patent Application Laid-Open No. 8-186667, since the content is recorded in an encrypted state, unauthorized digital copying can be prevented, but can be reproduced only by a dedicated terminal. In other words, it is not a suitable system when viewing the current music content from a way of enjoying. Further, the system described in Japanese Patent Application Laid-Open No. 8-186667 is not a system suitable for recording a broadcast because it is necessary to always communicate with an information center to obtain a recording permission at the time of recording.

On the other hand, there are some problems in the current digital broadcasting. With the current IRD, it is possible to digitally record music content by connecting a digital recording device such as an MD recording device. However, if you want to record only the desired song, the user can operate the digital recording device to start recording when the song you want to record is broadcast and stop recording at the end of the song, or It is necessary to perform an editing operation, such as deleting all songs other than the desired song after recording the entire song including other songs so that the song can be accommodated. In the former method, it is necessary to wait in front of the digital recording device from the start of recording to the end of recording, and it can be said that it is difficult to accurately grasp the start and end timings of a song. The latter method requires cumbersome editing after recording.

[0010] In the current MD, the title of a disc or a song can be input.
In the method of recording by connecting an MD recording device to D externally, editing work such as title input has to be performed by a user separately from the recording work, which is troublesome. This is the same when recording using a CD rental.

[0011] Further, as can be seen from the spread of CD rental, there is a need for users to record only their favorite songs and pay for them. However, the current digital broadcasting is not a billing system for each song, much less a system for billing in conjunction with recording. In other words, in the current digital broadcasting, users pay a fixed monthly contract fee regardless of recording. It can be said that this is a wasteful system to use instead of CD rental.

An object of the present invention is to provide a digital broadcast receiving and recording system which can record a favorite song and pay for the song by charging linked to the recording.

Another object of the present invention is to provide a digital broadcast receiving / recording system capable of simplifying an editing operation such as a troublesome recording operation and title input which occur with recording.

Still another object of the present invention is to provide a digital broadcast receiving / recording system which can prevent unauthorized digital copying and can reproduce and enjoy a digital broadcast recorded on a dedicated terminal other than the dedicated terminal. To provide.

[0015]

The decryption unit extracts the encryption key generation information from the digital music information and sends it to the management information storage device, and decrypts the digital music information using the encryption key obtained from the management information storage device, as before. The additional information processing means extracts additional information included in the digital music information. The condition determining means refers to the recording points included in the supplementary information and the remaining recording points recorded in the remaining recording point storage unit of the management information storage device,
If the remaining recording point is equal to or greater than the recording point, recording is permitted. If the remaining recording point is less than the recording point, recording is not permitted. When recording is permitted by the condition determining means, the writing / reading means writes the music data and the related information to the MD which is a music information storage medium. At this time, the related information is created in a predetermined configuration based on the contents of the supplementary information. The song data is SCMS

Using the encryption key sent from 3, the encrypted data 403 of the digital music information is decrypted.

As described above, the encrypted data 403 is
As shown in (b), it is composed of supplementary information 411 and music data 412. The song data extracting means 206 extracts the song data 412 from the decrypted encrypted data 403, and performs predetermined data processing, for example, conversion of the sampling rate if necessary. The reproducing means 207 reproduces the extracted music data 412 and outputs it from the speaker 230 as audio. The outline of the digital audio information listening control procedure in the digital broadcast receiving and recording terminal 2 has been described above.

Next, an outline of a recording control procedure of digital audio information in the digital broadcast receiving and recording terminal 2 will be described.

As described in the above-described listening control procedure, the received digital audio information is temporarily stored in the temporary storage unit 203. This is to enable recording from the beginning of the song and to allow recording for a while after listening. When recording is desired after listening to the digital audio information, the digital audio information desired to be recorded is designated by the recording operation means 213 to request the recording.

Here, the recording control procedure will be described with reference to the flowchart of FIG.

When recording is requested by the recording operation means 213, the digital broadcast receiving and recording terminal 2 starts recording control (step 601). Temporary control means 204 reads digital audio information 203 requested to be recorded from temporary storage section 203 (step 602). The decryption means 205 acquires the encryption key generation information 402 from the read digital audio information (step 603) and sends it to the management information storage device 3 via the management information storage device connection interface 212 (step 604). The decryption means 205 acquires the encryption key generated by the management information storage device 3 (step 605), and decrypts the encrypted data 403 of the digital music information (step 606).

The condition judging means 206 includes an additional information processing means 208
Then, the recording point 421 included in the supplementary information 411 is obtained (step 607). Next, a remaining recording point stored in the remaining recording point storage unit 302 of the management information storage device 3 is obtained (Step 608). The obtained remaining recording point is compared with the recording point 421 (step 609). If the remaining recording point is equal to or greater than the recording point 421, the recording is permitted and the process proceeds to step 610. If the remaining recording point is less than the recording point 421, the recording is not permitted and the process proceeds to step 614.

When recording is permitted by the condition determining means 209, the writing / reading means 210 records the music data 412 and related information on the music information storage medium 5 (step 6).
Ten).

Upon completion of the recording, the condition determining means 209
Remaining recording point update information is created with a value obtained by subtracting the recording point of the tune recorded from the remaining recording point acquired from the management information storage device 3 (step 611). The remaining recording point update means 209, based on the remaining recording point update information,
The remaining recording points stored in the remaining recording point storage unit 302 of the management information storage device 3 are updated (step 612).
Temporary storage control means 204 deletes the digital audio information recorded from temporary storage section 203 (step 613). The recording control ends (step 614).

As described above, according to the recording control procedure, it is possible to record a desired tune after listening.

The generation of an encryption key in the management information storage device 3 will be described. In the management information storage device 3, the encryption key generation information 402 sent from the digital broadcast reception / recording terminal 2 and the card encryption information stored in the card encryption information storage unit 303 by a predetermined method by the encryption key generation means 304. From the digital broadcast receiving and recording terminal
Send to 2.

The related information recorded on the music information storage medium 5 will be described. The related information is stored in the additional information processing unit 208.
Thus, the information is created in a predetermined configuration determined in advance from the contents of the extracted incidental information. In the first embodiment, an MD is used as the music information storage medium 5. The MD can record an arbitrary character string for each song in addition to the song data, and is used for recording the title of the song and the like. In the first embodiment, a character string to be recorded on the music information storage medium 5 as related information is formed from the song title 423 and the singer name 424 included in the supplementary information 411.

For example, as shown in FIG. 5, the song title 423 is "Bazooka! If the singer 424 is "Buster Yoshi" 502 ("" is not included), the character string recorded on the music information storage medium 5 is "Bazooka bastard!" ○ Buster Yoshi (excluding ""). In this example, ○ means a space (blank). In the first embodiment, from the song title 423 and the singer 424 of the supplementary information 411,
Although the character string to be recorded is configured, the method of configuring the related information to be recorded on the music information storage medium 5 such as which of the data included in the supplementary information 411 is to be used and how to configure the data are set in advance. If so, any format may be used, and it is not particularly limited to the example described in the first embodiment.

The recording of the music data 412 on the MD will be described. When recording music data on MD, record it by SCMS. In the first embodiment, the SCM
By using S, digital copying of recorded digital music information cannot be performed, and illegal digital copying can be prevented. On the other hand, song data and related information are recorded based on the format of the MD standard.
MD can be played and enjoyed normally on other MD playback devices.

In the above-described recording control procedure, the recording of digital audio information stored in the temporary storage unit 203 has been described. However, the tune to be recorded is designated in advance by the recording operation means 213 using, for example, a tune identifier 401 or the like. By doing so, scheduled recording is also possible.

[0049] For reservation recording, two settings are possible. First, recording is started when digital music information of a specified music piece is received. Second, even when digital music information of a designated music piece is received, recording is not immediately started, but is held in the temporary storage unit 203, and recording is performed according to a later recording request.

The reservation recording control procedure in the first setting will be described with reference to the flowchart of FIG. Recording operation means 213
When the timer recording is set, the timer recording control is started (step 701). Digital broadcast receiving means 202 receives digital music information (step 702). Temporary storage control means 204 includes a song identifier 401 of the received digital music information.
Is acquired (step 703), and compared with the song identifier of the song specified in the reserved recording (step 704). If not, the process proceeds to step 707. If they are the same, the received digital music information is stored in the temporary storage unit 203 (step 705), and then the process proceeds to recording control (step 706). Step 706
Is executed according to the recording control procedure described in the flowchart of FIG.

In the reservation recording control in the second setting,
Even if the temporary music control means 204 receives the digital music information of the designated music, it temporarily stores the digital music information in the temporary memory 203 and does not immediately shift to the recording control. Later, recording operation means
At the stage where the recording is requested by 213, the process shifts to the recording control. In this setting, it is possible to listen once, and finally select whether or not to record by the recording operation means 213. It should be noted that the digital music information once listened to is deleted from the temporary storage unit 203 irrespective of whether or not it is finally recorded.

As described above, the reservation recording control eliminates the need to perform a recording operation on the terminal at the time of broadcasting the music desired to be recorded, thereby improving usability.

In the digital broadcast receiving / recording terminal 2 according to the first embodiment, the digital music information recorded on the music information storage medium 5 is read out by the writing / reading means and reproduced by the reproducing means 207, thereby reproducing the music. The digital music information recorded on the information storage medium 5 can also be reproduced.

Next, updating of the remaining recording point information stored in the remaining recording point storage section 302 of the management information storage device 3 will be described. As will be understood from the description of the recording control procedure, the remaining recording points are consumed every time recording is performed. If the remaining recording points are exhausted, no further recording can be performed. Therefore, if it is desired to continue recording, it is necessary to add a recording point.

In this embodiment, recording points can be added by two methods. The first method is to install and use a dedicated terminal for updating the remaining recording points in a convenience store or the like. The user inserts the management information storage device 3 into the dedicated terminal and pays for the recording points to be added. The dedicated terminal is the remaining recording point storage unit 302
Is updated and the recording points for the price are added. This method is similar to purchasing a prepaid card such as a telephone card at a convenience store.

The second is a method of purchasing a recording point by communicating with a broadcasting center using a modem or the like. FIG.
FIG. 3 is a block diagram showing details of a second embodiment of the digital broadcast receiving and recording terminal 2. The difference from the first embodiment is that a center communication unit 801 is added. 2 are the same as those in FIG. 2 and the description is omitted. The user can purchase a recording point by communicating with the broadcasting center by the center communication means 801 as necessary.

The center communication means 801 is connected to a broadcasting center via a communication line using a modem 802 or the like, and transmits the number of recording points to be purchased. After collecting the fee by a predetermined method, the broadcasting center similarly transmits the remaining recording point update information to the digital broadcast receiving and recording terminal 2 via the communication line. The remaining recording point update information 209 is transmitted to the center communication unit 8
Based on the remaining recording point update information received in 01, the remaining recording points stored in the remaining recording point storage unit 302 are updated.

Regardless of the method used, once a recording point is purchased, the user can enjoy recording at his / her desired time without any particular contract or billing procedure until the remaining recording point is exhausted. it can.

In the first embodiment and the second embodiment, the recording point uses an arbitrary unit predefined by the system. However, for example, a monetary unit or the number of recordings may be used as a unit. Often, the invention is not limited to units of recording points.

As described above, in the first embodiment and the second embodiment, it is possible to record only the tune that the user listens to and likes, and the listening act corresponds to a trial listening to encourage recording.
However, if this is left as it is, the entire song can be heard without recording. Further, for example, when a reproduced sound output from a speaker is recorded, although the recording is analog recording, the recording cannot be limited to the analog recording, and the entire tune is recorded.

Therefore, from the viewpoint of trial listening, trial listening control for limiting the listening itself is necessary. Figure
9 is a specific example of the supplementary information 411 when performing the preview control. In FIG. 9, a reproduction range 901 is added. The reproduction range 901 is, for example, as shown in FIG.
2:15] 910 (excluding ""). This indicates that the music is played from a time of 1 minute 20 seconds to a time of 2 minutes 15 seconds. In the digital broadcast receiving and recording terminal 2,
As shown in FIG. 10, the music data extraction unit 206
01 is acquired from the accompanying information processing means 208, and only the music data in this range is reproduced by the reproducing means 207.

For example, if the reproduction range 901 is set so as to indicate only the first part of the music or a rust portion, it is possible to limit the listening to the case where no recording is performed while satisfying the purpose of the audition for prompting the recording. it can. In other words, the user of the digital broadcast receiving and recording terminal 2 must record the music in order to listen to the entire volume of the music.

The reproduction range 901 is not limited to the example shown in FIG. 9 as long as it can indicate an arbitrary reproduction range of the music. For example, if only the first track of a song is set to the listening range at all times, the playback range 901 is the playback time from the beginning, for example, "1:10" (meaning 1 minute and 10 seconds from the beginning).
It can also be. Similarly, it is not limited to the hour, minute, and second format.

In the first embodiment and the second embodiment,
By using MD as the music information storage medium 5, even if there is no digital broadcast receiving and recording terminal 2 which is a dedicated terminal, if it is a device that can reproduce MD, it can be listened again, and from the current way of enjoying music The system is easy to use. On the other hand, recording by SCMS can prevent unauthorized digital copying. Note that MD is used from the viewpoint of re-listening after recording.However, if MD can record additional information in addition to music data and some kind of copy protection such as SCMS can be applied, use this MD. It can be used as the music information storage medium 5 of the example. Therefore,
The present invention is not limited to using an MD at all.

In the first and second embodiments, an IC card is used as the management information storage device 3. However, there is no particular limitation as long as the same function can be realized.

[0066]

As described above, in the digital broadcast receiving and recording system of the present invention, when the condition is satisfied based on the remaining recording point information in the management information storage device, the digital music information is recorded and the accounting process is performed. With, recording linked to the recording is realized, and only the desired song can be recorded, and the price can be paid accordingly.

As another independent effect, recording control is performed in conjunction with the reception of digital music information, and not only music data but also additional information such as a song title is broadcast as digital music information, and additional information is recorded during recording. By recording the information in the music information storage medium, it is possible to simplify the cumbersome recording operation and editing work such as title input that occur with the recording.

As another independent effect, an MD is used as a music information storage medium, and received digital music information is recorded by SCMS to prevent unauthorized digital copying, and a digital broadcast reception which is a dedicated terminal. Even if it is recorded by the recording terminal, it can be played back and enjoyed by another MD reproducing device other than the digital broadcast receiving and recording terminal.
