  The present invention relates to a data processing apparatus and a data processing program for generating information indicating a section to be reproduced in program information (hereinafter referred to as reproduction information).

  2. Description of the Related Art In recent years, data processing devices that record and play back programs due to the increase in capacity and price of digital recording media such as optical discs and hard disks such as DVD-RAMs, digital recording of digital signals from VTR devices that record analog signals Shifting to a recording device. In addition, this trend is expected to accelerate with the start of digital terrestrial broadcasting.

  There are many advantages of recording with digital signals. One of them is the advantage of easy editing. For example, in the program material, digest playback that extracts and plays back only the part that the user wants to watch, and commercial cut playback that cuts the commercial material inserted between the program material and plays back only the program material, are easily realized. it can.

  For these, a playlist which is a general function of the data processing apparatus is used. The user designates the start point and end point of the necessary part in the recorded data and records it as a playlist. Thereby, digest playback, commercial skip playback, and the like are possible.

  However, in order to create a playlist, the user must search for a necessary portion from a large amount of recorded data and manually specify the start point and end point of the playback section.

  In view of this, there has been proposed one in which a commercial skip function realized in an analog recording apparatus is applied to a digital data processing apparatus (see, for example, Patent Document 1). The data processing apparatus in this proposal records program information including commercial material and position information indicating the position of the commercial material, and reproduces the program information by skipping the commercial based on the position information indicating the position of the commercial material. To do.

  Also, data processing methods and data processing that can efficiently record program information by transmitting and receiving information such as news inserted in a program and extended time of broadcasting over a network, not limited to commercials. An apparatus has also been proposed (see, for example, Patent Document 2). In this method, when a certain program is broadcasted, reproduction information including program start / end time, commercial / news start / end time, etc. based on the broadcast performance of the program is provided on the operator's server. The A user who has received and recorded the program can obtain playback information of the program by accessing the server of the operator through the network. Since the user reproduces the recorded program based on the obtained reproduction information, the user can reproduce the program while skipping commercials and news.

  Hereinafter, a conventional data processing apparatus will be described with reference to FIG. FIG. 11 is a block diagram showing a functional block diagram of a conventional data processing apparatus in a format that can be easily compared with the present invention.

  The conventional data processing apparatus stores the received program information in the recording medium 14. At that time, the program material information detection unit 13 detects information on the broadcast environment such as a broadcasting station and a broadcast date, and information on the encoding method and recording method from the program information, and accumulates them in the recording medium 14. The reproduction information transmission / reception unit 12 acquires reproduction information based on the broadcast performance of the received program information by accessing a provider's server via the network. The reproduction information includes, for example, time information of the broadcasted program, that is, data indicating the start point and end point of the program, and the start point and end point of the inserted data such as CM and news. The received reproduction information is also stored in the recording medium 14. The control unit 17 sends a control signal to the decoding unit 15 so as to decode the program information stored in the recording medium 14 based on the reproduction information. The decoding unit 15 decodes the program information under the control of the control unit 17. In addition, the control unit 17 sends a control signal to the reproduction information editing unit 16. Under the control of the control unit 17, the reproduction information editing unit 16 reads the reproduction information from the recording medium 14, and performs editing, recording, and the like.

As described above, the conventional data processing apparatus acquires reproduction information based on the broadcast performance via the network, and reproduces and edits the digital data based on the acquired reproduction information. Therefore, according to the conventional data processing apparatus, it is possible to automate reproduction and recording operations only for the main program.

The data processing device 20b can receive the broadcast wave from the broadcast station 18b by the receiving circuit 23b, and can record / reproduce and edit the received broadcast. The broadcast received by the data processing device 20b is decoded and output from the output terminal 27b and displayed on the display device 29b.

  The data processing device 20a and the data processing device 20b output or capture time management information and other information from the input / output terminal 25a and the input / output terminal 25b to the network 22. For example, the data processing devices 20a and 20b can access the databases 21a and 21b provided in the broadcasting stations 18a and 18b to acquire program information and the like. Further, the data processing device 20a can exchange data regarding, for example, broadcasted programs with the data processing device 20b via the network 22.

  An example of the data flow in the present embodiment is as follows. First, the data processing device 20a receives and records the program A1 information from the broadcasting station 18a. At that time, the data processing device 20a accesses the database 21a of the broadcasting station 18a to acquire and record the time management information of the program A1 information. On the other hand, the data processing device 20b receives and records program A2 information, which is a rebroadcast of the program A1 information, from the broadcasting station 18b. The data processing device 20b accesses the database 21b of the broadcasting station 18b to acquire and record time management information of the program A2 information. Furthermore, in the data processing device 20b, reproduction information for digest reproduction of the program A2 information is created and recorded by the user's manual work. The data processing device 20a acquires the time management information and digest reproduction information about the program A2 information recorded in the data processing device 20b via the network, and based on these information, the reproduction information about the program A1 information.

  The above data flow is an example, and the present invention is not limited to this.

  Further, the present invention is not limited to the system configuration shown in FIG. For example, in the system configuration shown in FIG. 1, in the data processing devices 20a and 20b, the data communication function including the input / output terminals 25a and 25b, the data output function including the output terminals 27a and 27b, and the receiving circuits 23a and 23b are one device. However, any one of the data communication function, the data output function, and the receiving circuit may be configured by another device, or the display devices 29a and 29b are incorporated in the data processing devices 20a and 20b. It may be a device. Further, the data processing devices 20a and 20b can further include at least one of a function for reproducing and editing recorded program information.

  In addition, a program for realizing the functions included in the data devices 20a and 20b is installed in an arbitrary personal computer or a dedicated device, for example, from a recording medium such as a CD-ROM or downloaded via a communication line. Thus, a data processing apparatus can be configured.

  FIG. 2 is a block diagram showing the configuration of the data processing device 20a. As shown in FIG. 2, the data processing device 20a includes a time management information transmission / reception unit 1, a reproduction information transmission / reception unit 2, a time information detection unit 3, a program material information detection unit 4, a time management information editing unit 5, a recording medium 6, A decoding unit 7, a time management information difference calculation unit 8, a reproduction information generation unit 9, a reproduction information editing unit 10, and a control unit 11 are provided. In the present embodiment, the data processing device 20b has the same configuration as that shown in FIG.

  The program information received from the broadcasting station 18a by the data processing device 20a passes through the time information detection unit 3 and is recorded on the recording medium 6. The program information is broadcast, for example, in a stream format defined by the MPEG-2 standard.

  The time information detection unit 3 detects and extracts time information from the received program information. The time information is information indicating the start position and the end position of the program material and insertion material included in the program information. The time information is sent together with the program material through broadcasting, or is sent from the broadcasting station as a data broadcast before the program material is broadcast or after the program material is broadcast. The time information detector 3 mainly detects time information.

  The program material information detection unit 4 detects program material information from the received program information. The program material information includes, for example, program specifying information for specifying a broadcasting environment such as a broadcasting station, a broadcasting date, and a program name, encoding information such as a data format and a transfer rate of the program information, and the like. The program material information detection unit 4 acquires program material information from, for example, PSI (Program Specific Information), SI (Service Information), and header information of the program material included in the program information. PSI is information necessary for selecting a required program defined in the MPEG system standard, and SI is program arrangement information defined by ARIB (Association of Ratio Industries and Businesses).

  The time management information editing unit 5 generates time management information by combining the time information detected by the time information detection unit 3 and the program material information detected by the program material information detection unit 4.

  The time management information is recorded on the recording medium 6 in association with the program information. The recording medium 6 stores program information, time management information, and reproduction information in different areas.

  The time management information may be detected and generated from the program information received in this way, but may be received from a network or external media. The time management information transmission / reception unit 1 receives time management information as a data stream from, for example, an external medium such as a network or a CD-ROM, and records the data in the recording medium 6.

  The time management information transmitting / receiving unit 1 can obtain, for example, time management information of a program broadcast received from the broadcast station 18a from the database 21b of the broadcast station 18a via a network and record it on the recording medium 6. Also, time management information of the same material program information broadcast in the broadcasting environment different from the broadcasting station 18a, that is, the broadcasting station 18b, can be acquired from the database 21b of the broadcasting station 18b and recorded in the recording medium 6. Further, the time management information transmitting / receiving unit 1 may transmit the time management information recorded on the recording medium 6 to a network or an external medium.

  The reproduction information transmission / reception unit 2 receives reproduction information from the outside of a data processing apparatus such as an external medium such as a network or a CD-ROM, and records it on the recording medium 6. Also, the time management information recorded on the recording medium 6 is transmitted to a network or an external medium. The reproduction information includes, for example, a playlist indicating the start point and end point of the section to be reproduced.

  The time management information difference calculation unit 8 calculates a difference in time management information based on the time management information recorded on the recording medium 6. For example, the time management information editing unit 5 edits and records the time management information based on the program information received from the broadcasting station 18a, and the same material acquired by the time management information transmitting / receiving unit 1 from the database 21b of the broadcasting station 18b. The difference between the program information and the time management information is calculated.

  The reproduction information generating unit 9 is recorded on the recording medium 6 based on the reproduction information received by the reproduction information transmitting / receiving unit 2 from the outside and recorded on the recording medium 6 and the difference information calculated by the time management information difference calculating unit 8. The reproduction information for reproducing the program information is calculated.

  The reproduction information editing unit 10 edits reproduction information recorded on the recording medium 6.

  Further, when the program specifying information is changed, or when the reproduction information referring to the program material is changed, the time management information editing unit 5 changes the contents of the time management information recorded on the recording medium 6. To do.

  The control unit 11 outputs control signals to the time management information difference calculation unit 8, the reproduction information generation unit 9, the reproduction information editing unit 10, and the decoding unit 7, and records the time management information and reproduction information recorded on the recording medium 6. Based on the above, the desired reproduction information is obtained. Specifically, based on various information described in the time management information, processing for reading out related program information, time management information, reproduction information, etc. from the recording medium 6, processing for calculating based on the read data, recording medium 6 is controlled. The control unit 11 controls the decoding unit 7 based on the reproduction information, and reproduces the program information by decoding the program information.

  Next, the processing flow of the data processing device 20a in the present embodiment will be described with reference to FIGS. FIG. 3 shows a process from when the data processing apparatus 20a records program information until it acquires reproduction information and time management information from the data processing apparatus 20b and calculates reproduction information usable in the data processing apparatus 20a. It is the flowchart shown.

  First, the data processing device 20a receives the data of the program A1 information from the broadcasting station A18 and records it on the recording medium 6 (S1). It is assumed that the program A1 information includes the program material G. FIG. 4 is a diagram showing an example of recorded program A1 information. As shown in FIG. 4, the program A1 information is composed of program materials G1 to G4 and materials (inserted materials) 32 to 35 other than the program materials. The inserted material is margin data 32 and 33 provided for reliably recording the program, the commercial 34 inserted in the program, and the news 35 inserted in the program A1.

  The data processing device 20a starts recording the program A1 information from the recording start point 36, and records the program material G1 from the program start point 37. The CM 34 is recorded from the CM start point 38, the recording of the CM 34 is ended at the CM end point 39, and the recording of the program material G2 is resumed. The editing start point 40 and the editing end point 41 indicate positions (time information) from which part of the data of the program material G is deleted, and the data processing device 20a can recognize the program materials G2 and G3 without being aware of the editing points. Make a record. The news 35 is recorded from the news start point 42, the recording of the news 35 is ended at the news end point 43, and the recording of the program material G4 is resumed. The program ends at the program end point 44 and the recording ends at the recording stop point 45.

  Next, as shown in FIG. 3, time management information B1 of the data of the program A1 information recorded in S1 is generated (S2). As described above, the time management information B1 is time management of time information detected from the program A1 information by the time information detection unit 3 and program material information detected from the program A1 information by the program material information detection unit 4. It is generated by the information editing unit 5 editing. The generated time management information B1 is recorded on the recording medium 6 (S3).

  The time management information acquisition / generation method is not limited to this. For example, based on the information obtained by the program material information detection unit 4 analyzing the header information of the program material G included in the program A1 information recorded in S1, the time management information transmission / reception unit 1 is connected via the network. The time management information of the program A1 information can be acquired from the database 21a of the broadcasting station 18a.

  Here, the time management information will be described. FIG. 5 is a diagram illustrating an example of a data configuration of the time management information B1 related to the program A1 information including the program material G. The time management information B1 includes program identification information 47, program material identification information 48, reproduction information identification information 49, and time information 50.

  The program specifying information 47 is information for specifying a broadcast environment in which the program material G is broadcast, and includes, for example, a program name, a broadcasting station, a broadcasting date and time, a channel number, an event number, and the like. The event number is a number that uniquely determines a program defined in ARIB. The program identification information 47 identifies the program A1 handled by the time management information B1. For example, in the database 21a of the broadcasting station 18a, information such as which program was broadcast in which broadcasting environment is recorded. In this database 21a, a key for searching for the program A1 handled by the time management information B1. This information is the program specifying information 47.

  The program material identification information 48 is information for identifying the program material G. By the program material identification information 48, the program material G and the time management information B1 are associated. The program material identification information 48 is information issued by the creator who created the program material, and is information that makes it possible to uniquely identify the program material. For example, the broadcasting station 18a, which is the publisher that issued the program material identification information, or the authority that has the rights, manages the program material identification information on the database 21a. For example, when the broadcasting station 18b broadcasts the program A2 including the program material G, program specifying information for specifying the program A2 is registered in the database of the broadcasting station 18a. The program specifying information of the registered program A2 and the program material identification information of the program material G are managed in association with each other on the database 21a. As described above, when a program including the program material G is broadcast, the program specifying information of the program is registered in the database 21 a and managed in association with the program material G. The program material identification information 48 shown in FIG. 5 represents the identification information (XXXXXXX) of the program material G.

  The reproduction information specifying information 49 includes, for example, reference data and a reference data length. The reference data is a reproduction information name of reproduction information referring to the program A1 information specified by the program specifying information 47. The reference data length is a data length of data referred to by reproduction information that refers to the program A1 information. The reproduction information specifying information 49 associates reproduction information referring to the program A1 information and time management information B1 related to the program A1 information. Since the reproduction information specifying information 49 specifies reproduction information by a reproduction information name (reference data) and a reference data length, even when there are a plurality of pieces of reproduction information having the same reproduction information name, they can be distinguished.

  When the program A1 information is received and recorded on the recording medium 6, playback information (hereinafter referred to as playback information C1) having a playback section from the recording start point 36 to the recording end point 45 (see FIG. 4) in the program A1 information. Is also recorded on the recording medium 6. The control unit 11 detects the recorded reproduction information C1 from the recording medium 6, and the time management information editing unit 5 adds the reproduction information name of the reproduction information C1 to the time management information B1.

  When the data processing device 20a acquires only the time management information and the reproduction information and the program information are not recorded on the recording medium 6, the data processing device 20a is based on the reproduction information specifying information described in the acquired time management information. In addition, it is possible to acquire from the network or receive broadcasts when necessary.

  The time information 50 indicates, for example, the broadcast performance of the program on the time axis like an electronic program guide. An item having a start point, an end point, and an interval described in the time information 50 is called an action.

  Time information such as a start point, an end point, and an interval in reproduction information and time information is represented by PTS (Presentation Time Stamp). PTS is a value defined by the MPEG-2 standard, and the display timing of each frame is digitized with an accuracy of 90 kHz.

  The program start point 37, program end point 44, CM start point 38, CM end point 39, edit start point 40, edit end point 41, news start point 42, and news end point 43 in the program A1 information of FIG. It is described as the action of the time information 50. The start point of the program action 51 indicates the program start point 37, the end point of the program action 51 indicates the position of the program end point 44, and the interval between the program actions 51 indicates the interval from the program start point 37 to the program end point 44. Yes. The start point of the CM action 52 indicates the CM start point 38, the end point of the CM action 52 indicates the CM end point 39, and the interval of the commercial action 52 indicates the interval from the CM start point 38 to the CM end point 39. The start point of the edit [delete] action 53 indicates the edit [delete] start point 40, the end point of the edit [delete] action 53 indicates the edit [delete] end point 41, and the interval of the edit [delete] action 53 is deleted. The interval between the parts is shown. The start point of the news action 54 indicates the news start point 42, the end point of the news action 54 indicates the news end point 43, and the interval of the news action 54 indicates the interval from the news start point 42 to the news end point 43.

  As described above, the time information 50 includes the start and end points of the program material G, the interval between the program materials G, the start and end points of data other than the program material G, and the program in the program A1 information including the program material G. It includes information indicating the interval of data other than the material G, and when the program material G is edited, the edit start point and end point, and the interval of the edit portion, in units of frames.

  This completes the explanation of the time management information. Next, the reproduction information transmission / reception unit 2 and the time management information transmission / reception unit 1 acquire reproduction information D2 as reference reproduction information and time management information B2 as reference time management information (S4, S5). In the present embodiment, the reproduction information D2 is reproduction information created based on the same material program information (program A2 information) rebroadcasted for the same program material G in a broadcast environment different from the program A1 information. The time management information B2 is time management information regarding the program A2 information. The reproduction information D2 and the time management information B2 are generated when, for example, the program material G is rebroadcast as program A2 information at the broadcasting station 18b shown in FIG. 1, and the data processing device 20b receives and records it. Information.

  The data processing device 20a requests the reproduction information D2 from the data processing device 20b via the network 22. The data processing device 20b transmits the reproduction information D2 and time management information B2 of the program A2 information referred to by the reproduction information D2 to the data processing device 20a. The data processing device 20a obtains the reproduction information D1 of the program A2 information in the data processing device 20a based on the received reproduction information D2 and the time management information B1 recorded in the time management information B2 and S3.

  Here, the reproduction information D2 and the time management information B2 will be described.

  First, the time management information B2 will be described. FIG. 6 is a diagram showing program A2 information recorded by the data processing device 20b. The program A2 information includes actual data of the program material G, margin data 56 and 57 provided for reliably recording the program, CM 58 inserted in the program, and news 59 inserted in the program. The data processing device 20b starts recording from the recording start point 60 and records the program material G1 from the program start point 61. The CM 58 is recorded from the CM start point 62, the CM 58 recording ends at the CM end point 63, and the recording of the program material G2 is resumed. The editing start point 64 and the editing end point 65 indicate positions (time information) where the data of the program material G is partially deleted. The data processing device 20b records the program materials G2 and G3 without being aware of the editing point. I do. The news 59 is recorded from the news start point 66, the recording of the news 59 is ended at the news end point 67, and the recording of the program material G4 is resumed. The program ends at the program end point 68, and the recording ends at the recording stop point 69.

  In the program A2, CM 58 and news 59 are inserted and the program material G is edited as in the case of the program A1 broadcast on the broadcasting station 18a. However, the CM58 time in the program A2 information is different from the CM34 time in the program A1 information broadcast by the broadcasting station 18a.

  FIG. 7 is a diagram showing time management information B2 acquired by the data processing device 20b from the broadcasting station 18b. The time management information B2 includes program identification information 71, program material identification information 72, reproduction information identification information 73, and time information 74. The program start point 61, program end point 68, CM start point 62, CM end point 63, edit start point 64, edit end point 65, news start point 66, and news end point 67 in the program A2 information of FIG. It is described as an action of the time information 74. The start point of the program action 75 indicates the program start point 61, the end point of the program action 75 indicates the position of the program end point 68, and the interval between the program actions 75 indicates the interval from the program start point 61 to the program end point 68. Yes. The start point of the CM action 76 indicates the CM start point 62, the end point of the CM action 76 indicates the CM end point 63, and the interval of the CM action 76 indicates the interval from the CM start point 62 to the CM end point 63. The start point of the edit [delete] action 77 indicates the edit [delete] start point 64, the end point of the edit [delete] action 77 indicates the edit [delete] end point 65, and the interval of the edit [delete] 77 is the deleted portion. The interval is shown. The start point of the news action 78 indicates the news start point 66, the end point of the news action 78 indicates the news end point 67, and the interval of the news action 78 indicates the interval from the news start point 66 to the news end point 67.

  Here, although the program identification information 47 shown in FIG. 5 and the program identification information 71 in FIG. 7 are different, the program material G itself is the same, so the program material identification information 48 and the program material identification information 72 are the same identification information ( XXXXXXXXX). This relationship is managed by the broadcasting stations 18a and 18b.

  The reproduction information specifying information 49 and 73 is information specific to the reception environment. Since the place where the program A1 information including the program material G and the program A2 information exist is the recording medium 6 of each data processing device 20a, 20b, the respective reproduction information specifying information 49, 73 have different values. The reproduction information specifying information 73 is used to associate the time management information B2 and the reproduction information D2.

  The action items of the time information 50 and the time information 74 are the same, but the start points and intervals of the CM action 52 and the CM action 76 are different, and accordingly, the end points and intervals of the program action 51 and the program action 75 are also different.

  Next, the reproduction information D2 will be described. Here, the reproduction information D2 refers to the program A2 information, and is a playlist in which the start point and end point of the portion to be reproduced are represented by PTS. The reproduction information D2 is a playlist for digest reproduction of the program A2 information created by the data processing device 20b. Digest playback is playback by designating only the program material G or a portion that the user wants to play as a playback section, for example, by PTS. The digest playback playlist is created, for example, by the user searching for a necessary part from the recorded program A2 information and manually specifying the start point and end point.

  FIG. 8A shows an example of the reproduction information D2. The reproduction information D2 is reproduction information for reproducing only a specific part in the recorded data. FIG. 9A shows a playback section indicated by the playback information D2 in the program A2 information. The playback sections indicated by the playback information D2 are playback sections 87 to 90 in FIG. Reproduction sections P1, P2, P3, and P4 in FIG. 8A represent the reproduction sections P1, P2, P3, and P4 in FIG. 9A. IN of the reproduction section P1 of the reproduction information D2 in FIG. 8A indicates the reproduction start point 91 in FIG. OUT in the playback section P4 in FIG. 8A indicates the playback end point 92 in FIG.

  The reproduction information D2 created by the data processing device 20b may be disclosed to the outside by another communication means other than the data processing device 20b, for example, a home page or a mobile terminal. By disclosing the reproduction information D2, the user of the data processing device 20a can know the existence of the reproduction information D2, and can request the reproduction information D2 from the data processing device 20b. As a result, the reproduction information D2 and time management information B2 created by the data processing device 20b are transmitted to the data processing device 20a.

  The above is the description of the reproduction information D2 and the time management information B2. 3 again, the time management information difference calculation unit 8 in the data processing device 20a calculates the difference B between the time management information B1 (see FIG. 5) and the time management information B2 (see FIG. 7) (S6). ).

  The difference B is obtained, for example, by calculating a PTS difference for each action of the time information 50 of the time management information B1 and the time information 74 of the time management information B2. Details of an example method for calculating the difference B will be described below.

Looking at the difference between the program actions 51 and 75 in the time information 50 and 74 shown in FIG. 5 and FIG. 7, the difference at the starting point is 0 (see Equation 1).
(Formula 1)
180000 (start point of program action 51) -180000 (start point of program action 75) = 0
The difference between the end points is −50000 (see Equation 2). That is, the program action 51 ends by 50,000 earlier than the program action 75.
(Formula 2)
17510313 (end point of program action 51) -17560313 (end point of program action 75) = − 50000
Similarly, when looking at the CM actions 52 and 76, the difference between the start points is −50000 (see Equation 3). That is, the CM action 52 starts 50000 earlier than the CM action 76.
(Formula 3)
4000000 (starting point of CM action 52) −4050000 (starting point of CM action 76) = − 50000
The difference between the end points is −100,000 (see Equation 4). That is, the CM action 52 ends by 100,000 times earlier than the CM action 76.
(Formula 4)
5000000 (end point of CM action 52) −5100000 (end point of CM action 76) = − 100000
The difference between the intervals is −50000 (see Equation 5).
(Formula 5)
1000000 (interval of CM action 52) −1050000 (end point of CM action 76) = − 50000
Hereinafter, the difference can be similarly calculated for other actions.

  Based on the difference B calculated in this way, the reproduction information editing unit 10 calculates reproduction information D1 for the program A1 information recorded on the recording medium 6. For example, first, the difference D between the reproduction information D2 and the obtained reproduction information D1 can be calculated (S7), and the reproduction information D1 can be obtained from the difference D (S8). FIG. 8B is a diagram illustrating an example of the calculated reproduction information D1.

  Details of a calculation example of the reproduction information D1 shown in FIG. 8B will be described below. Here, each reproduction section P1 to P4 of the reproduction information D2 is sequentially obtained on the time axis (from the smaller PTS to the larger one), and compared with the values of the start and end points of each action, The reproduction information D1 is obtained by calculating the difference from the reproduction information D2. For example, the difference between each action is reflected on the playback sections P1, P2, P3, and P4 along the time axis, thereby obtaining the playback sections Q1, Q2, Q3, and Q4 corresponding to the sections. The obtained reproduction sections Q1 to Q4 are reproduction information D1.

The action of the time information 74 in FIG. 7 and the playback sections P1 to P4 in FIG. 8A are as shown in the following (formula 6) on the time axis.
(Formula 6)
Start point of program 75 <IN of playback section P1
<OUT of playback section P1 = start point of CM action 76 <End point of CM action 76 = IN of playback section P2
<End point of playback section P2 = start point of editing 77 ...
First, a reproduction section Q1 corresponding to the reproduction section P1 is obtained. The difference between the IN of the playback section P1 and the IN of the playback section Q1 to be obtained is 0 because the difference between the start point of the program 75 and the start point of the program 51 is 0 (see Equation 1). The difference between OUT in the playback section P1 and OUT in the playback section Q1 is −50000 because the difference between the start point of the CM action 52 and the start point of the CM action 76 is −50000 (see Equation 2). If the OUT in the playback section Q1 is not faster than the OUT in the playback section P1 by 50000, the CM will be played back. Accordingly, IN is 250,000 and OUT is 4000000 in the playback section Q1. The difference between the playback interval P1 length interval and the playback interval Q1 length interval is −50000 (OUT difference) −0 (IN difference) = − 50000. Therefore, the length interval of the playback section Q1 is 3750000 shorter than the length interval of the playback section P1 by 50,000.

  Similarly, a playback section Q2 corresponding to the playback section P2, a playback section Q2 corresponding to the playback section P2, and a playback section Q3 corresponding to the playback section P3 are obtained. As described above, the reproduction information D1 can be obtained while reflecting the difference of actions (difference of time management information) along the time axis in the difference of reproduction sections (difference of reproduction information). The reproduction information D1 is recorded on the recording medium 6 (S9).

  FIG. 9B is a diagram showing the playback section indicated by the playback information D1 shown in FIG. 8B in the program A1 information. The playback sections indicated by the playback information D1 are playback sections 81 to 84 in FIG. 9B. Reproduction sections 81 to 84 in FIG. 9B represent the reproduction sections Q1 to Q4 in FIG. The reproduction start point 85 indicates the start point of the reproduction section Q1 of the reproduction information D1. The reproduction end point 86 indicates the end point of the reproduction section Q4 of the reproduction information D1 in FIG. 9B is exactly the same as the program material G in the section from the playback start point 85 to the playback end point 86 and in the section from the playback start point 91 to the playback end point 92 in FIG. Are reproduced in units of frames. Therefore, although the program A2 information and the broadcast environment are different, even in the environment of the data processing device 20a in which the program A1 information including the same program material G is recorded, the reproduction information B2 about the program A2 information created by the data processing device 20b is included. It is possible to perform digest reproduction according to the above. If there is no change in the program material G itself, the reproduction information D2 and the reproduction information D1 faithfully reproduce the same part of the program material G in units of frames.

  The reproduction information D1 is obtained through the above flow. The user can automatically calculate the reproduction information D1 that can reproduce the program material G in his or her environment just by acquiring the necessary reproduction information D2 and time management information B2 in the same manner as the reproduction information D2.

  The processing for obtaining the reproduction information D1 is processing when the received program A1 information and program A2 information are recorded as they are in the data processing device 20a and the data processing device 20b. In this case, the amount of change in the PTS of each frame is the same in the program information when broadcast and the program information when recorded. However, depending on the recording method of program information, for example, the number of frames of image and sound and the encoding method, a unit amount (for example, PTS) representing the time of the time information of the program information is converted when recording the program information. There is. For example, this is a case where the data processing device 20a re-encodes and records the received program A1 information. In this case, for example, when the number of frames in 1 GOP (Group of Pictures) of recorded data increases, the amount of change in PTS between frames decreases. GOP (Group of Pictures) is a coding unit defined in order to enable random access to images according to the MPEG standard. Since the time management information B1 of the program A1 information is represented by the time unit amount of the program A1 information before being re-encoded and recorded, the PTS of the recorded program A1 information is the PTS of the time management information B1. Will be different. Therefore, the PTS of the action described in the time information of the time management information B1 is different from the PTS of the program A1 information actually recorded on the recording medium 6. Therefore, in order to refer to a designated frame, it is necessary to consider the ratio of the amount of change in PTS between frames (hereinafter referred to as change rate R1). Here, the change rate R1 is a ratio between the PTS change amount between frames in the time information of the time management information B1 of the program A1 information and the PTS change amount between frames of the program A1 information recorded on the recording medium 6. .

  The change rate R1 can be obtained, for example, as follows. When the program material detection unit 4 detects the program material information, the program material detection unit 4 obtains information indicating whether the time information of the program information has not been converted, or if it has been converted, what type of recording has been performed. Based on this information, the time management information difference calculation unit 8 calculates a change rate R1 of time information and uses it when calculating difference information. Further, the rate of change R1 can be calculated from the time information described in the program material G and the time information of the time management information B1. When the rate of change R1 is calculated, re-encoding is performed when the program information is recorded, and even when the time information is converted, the reproduction information generation unit 9 considers the rate of change R1 to reproduce the reproduction information. Can be requested.

  In the process shown in FIG. 3, when the reproduction information is obtained using the change rate R1, for example, a step of calculating the change rate R1 is added between S5 and S6. In S6, the time management information difference calculator 8 multiplies the PTS by the rate of change R1 to obtain the correlation of the amount of change, and calculates the difference B by the four arithmetic operations of PTS. In S7, the reproduction information generation unit 9 calculates a difference D based on the difference B and the change rate R1, and obtains reproduction information D1 from the reproduction information D in S8.

  The above is the description of the process for calculating the reproduction information D1. The data processing device 20a can reproduce only the reproduction section indicated by the reproduction information D1 in the program A1 information. Further, the data processing device 20a can record only the reproduction section indicated by the reproduction information D1 in the program A1 information on the recording medium 6, and can edit the recorded data.

  As described above, the user of the data processing device 20a acquires the reproduction information D2 about the program A2 information created by the user of the data processing device 20b and uses it for the program A1 information recorded in the data processing device 20a. be able to. Therefore, according to the data processing devices 20a and 20b in the present embodiment, it is possible to exchange and share reproduction information between users regardless of the difference in broadcasting environment. As a result, the user of the data processing device 20a can obtain reproduction information for reproducing only a part required by the user such as a digest reproduction playlist without manually specifying a reproduction section. Become.

  In the present embodiment, the target reproduction information D1 is finally calculated, but the difference D between the reproduction information D2 and the reproduction information D1 may be used as the reproduction information. In this case, the data processing device 20a can reproduce or record the same interval as the reproduction interval indicated by the reproduction information D1 based on the reproduction information D2 and the difference D.

Further, in the present embodiment, the processing of the data processing device 20a has been described, but the data processing device 20b can perform the same processing.
(Embodiment 2)
FIG. 10 is a diagram illustrating an example of a configuration of a system including the data processing device according to the second embodiment. Since the configuration of the data processing devices 20a and 20b in the second embodiment is the same as the configuration of the data processing devices 20a and 20b shown in FIG. 2, detailed description thereof is omitted.

  In this embodiment, a program broadcast in the same broadcast environment is received by a plurality of data processing devices, and each data processing device calculates a playlist for performing digest reproduction on the program information. As an example, the program H broadcast from the broadcasting station 93 (here, a song program in which a plurality of singers appear) is recorded by the data processing device 20a and the data processing device 20b, and the program H information from the broadcasting station 93 is recorded. A case where the time management information and the reproduction information are acquired will be described.

  In FIG. 10, the data processing devices 20a and 20b receive broadcast waves from the broadcast station 93 using the receiving circuits 23a and 23b, and record them as program H information. The recorded program H information is decoded and output from the output terminals 27a and 27b and displayed on the display devices 29a and 29b. The data processing devices 20 a and 20 b obtain time management information related to the recorded program H information from the database 94 of the broadcasting station 93 through the network 22. The time management information may be provided to the data processing devices 20a and 20b together with the program H information by broadcast waves. The data processing devices 20a and 20b output information about the program H and other information from the input / output terminals 25a and 25b to the network 22 and import them.

  When broadcasting the program H, the broadcast station 94 prepares reproduction information (hereinafter referred to as a digest playlist) that can be digest-reproduced for each singer who appears, and can be obtained from the data processing devices 20a and 20b. To be disclosed. The digest playlist may be disclosed through the network 22 or through broadcasting. The user of the data processing device 20a obtains only the digest playlist about the singer that he / she wants to watch by the data processing device 20a, and performs playback or editing.

  In the data processing devices 20a and 20b, when the received program H information is recorded, the program H information may be converted and recorded. For example, when the data recording method of the data processing device 20a is a recording method for recording after re-encoding the received program information, the amount of change between PTS frames of the recorded data after re-encoding is: This is different from the PTS change amount between frames of received data before re-encoding. In such a case, the unit amount indicating the time of the time information included in the program H information recorded by the data processing device 20a is a unit indicating the time of the time information included in the digest playlist provided by the broadcasting station 93 or the time management information. Will be different. Therefore, even if the data recorded by the data processing device 20a is reproduced using the digest playlist provided by the broadcasting station 93, the intended digest reproduction cannot be performed.

  Here, when the digest playlist provided by the broadcasting station 93 is a playlist that specifies time information of playback information using a standard time (system time) as in the conventional recording / playback system, it relates to the recording system. And can be played back on time according to the playback information. However, there may be an error in the system time of the data processing devices 20a and 20b, so that the accuracy of the digest playlist is low. In addition, when the time information of the reproduction information is specified using the standard time (system time), since reproduction and editing cannot be performed in units of frames, for example, compared to a playlist in which time information is specified by PTS, Accuracy is reduced.

  Therefore, for example, when the broadcast data is re-encoded and recorded, the data processing device 20a uses the PTS change amount between the frames of the broadcast data and the frames of the re-encoded data. A ratio with the PTS change amount is calculated as a change rate. Considering this rate of change, a digest playlist suitable for the program H information recorded by the data processing device 20a is obtained.

  Specifically, for each action, the reproduction information is calculated by calculating the PTS difference between the start point, the end point, and the interval in consideration of the rate of change of the PTS. Therefore, even when the PTS is redefined by re-encoding, a playlist that refers to the same frame as the data before redefinition can be calculated. The broadcast station 93 can create and provide a digest playlist based on the time management information without having to consider the difference in recording method between the data processing devices 20a and 20b.

  Although the data processing apparatus 20a has been described in the present embodiment, the same applies to the data processing apparatus 20b.

  In the first and second embodiments, the exchange of reproduction information and time management information is not only performed directly between data processing apparatuses via a network, but may be indirectly acquired via another network path or an external medium. .

  Further, the action is not limited to the above-described action, but is determined based on the broadcast environment, and includes information necessary for calculating the difference information of the time information due to the difference in the broadcast environment.

  The start point, the end point, and the interval are expressed by PTS. PTS indicates the timing at which program information is displayed, and the time information indicates the timing on the time axis. Therefore, the start point, the end point, and the interval may be expressed by offset information such as the frame number to be displayed from a specific frame.

  The program information is broadcast in the stream format defined in the MPEG-2 standard. However, if the time management information can be acquired and databased together with the program material identification information, the program information data The format and delivery method are not limited to this example.

  In addition, as an example of the reproduction information, the program information is referred to and a play list in which the start point and end point of the portion to be reproduced is represented by PTS. However, the reproduction unit of the program information can be designated and reproduced based on it. As long as the data is correct.

  In addition, although an example of reproduction information is a playlist that refers to one program material, the reproduction information may be a playlist that refers to a plurality of program materials. An example of a playlist that refers to a plurality of program materials is a Virtual Play List in the Blu-Ray Rewritable standard.

  Further, the program material specifying information of the time management information is the program name, broadcasting station, broadcasting date and time, channel number, and event number, but any information that can uniquely specify the broadcasting environment and the program material may be used.

  The reproduction information specifying information of the time management information is a playlist name that refers to the program information specified by the program specifying information of the time management information and the data length of the program information, but the address on the network indicated by HTTP As described above, information indicating a position where reproduction information referring to program information exists, information for uniquely specifying time management information and reproduction information may be used.

  The time information of the time management information is the action start point, end point, and interval expressed in PTS, but the program information shows how the program information was broadcast in time series. As long as the start frame and the offset information indicating the number of frames from the start frame are information that can identify the position in the action and the program information.

  Further, in the present embodiment, the target reproduction information is finally calculated, but a difference between the reference reproduction information and the target reproduction information may be obtained and used as the reproduction information.

  According to the embodiment of the present invention, by calculating the difference in the time information of the program information due to the difference in the broadcast environment or the reception environment, and creating or editing the reproduction information, it is possible for all users to be the same for the same program material. Can be recorded, played back and edited.

  The data processing apparatus and the data processing program of the present invention are broadcasts about the same program material as the broadcast recorded in the data processing apparatus, and broadcast reproduction information in a different broadcast environment or reception environment can be used in the data processing apparatus It is useful as a data processing apparatus and a data processing program that can be used as various reproduction information.
