JP 2003-208756 A

  In recent years, the spread of digital broadcasting has been rapidly progressing, and in addition to CS digital broadcasting and BS digital broadcasting, digital broadcasting services using terrestrial waves have begun, and various types of content (program data) can be viewed and recorded through digital broadcasting. Can be done. In digital broadcasting, since program data is compressed and digitized, a program can be recorded on a hard disk device (hereinafter abbreviated as HDD), which is a general digital data storage medium, and is widely used. For example, a digital broadcast receiving device with a built-in HDD can be used for receiving digital broadcasts and recording received program data.

  In addition, with the diversification of digital broadcast programs, the usage of viewing program data after recording it on a storage medium is increasing. As a medium for recording the received program data, a removable recording medium such as a DVD (Digital Versatile Disk) or a removable HDD has been used in addition to the HDD. Thus, the user can select a medium for recording program data according to his / her preference and application.

  On the other hand, the HDD built in the digital broadcast receiving apparatus can record a large amount of program data, and has an advantage that the recorded program can be easily reproduced. However, the HDD cannot be easily exchanged or carried. is there. For this reason, there is a demand for medium change in which program data recorded on the HDD is desired to be recorded (copied or moved) on a removable recording medium such as a DVD or a removable HDD.

  However, digital copy program data is subjected to digital copy control for the purpose of copyright protection. Specifically, copy control information such as what can be recorded without restriction by a digital broadcast receiving apparatus, etc., which allows recording only once but does not permit further copying (“copy once”), and does not permit recording itself. Is added to each program.

  For example, in Patent Document 1, when the copy control information is copy-once, a program having the control information is not a non-exchangeable recording medium such as an HDD, but a second recording medium can be replaced. A process of recording on a recording medium is disclosed.

  As described above, the digital broadcast program is basically subjected to “copy once” copy control, and a program once recorded cannot be copied to another recording medium. For this reason, there was a problem that the user could not do what was normally done with the conventional analog broadcasting, and the convenience of the user deteriorated. For example, programs on home and mobile devices where programs recorded on the HDD cannot be backed up while remaining on the HDD, or programs recorded on the home recording control device are copied to the mobile device for viewing. At present, it is very inconvenient because it cannot share data.

  Since program copying is restricted in this way, when attempting to move a recorded program to another recording medium, the user moves the program. However, there is a problem in that when trying to move a “copy once” program to another recording medium, if the move fails for some reason, important data is lost. In addition, there is a problem that it is not possible to cope with a case where the user accidentally performs an operation and moves unintentionally. In addition, in the case of HD (High Definition) resolution programs where the number of scanning lines is increased to improve image quality, the image quality is reduced to standard definition SD (Standard Definition) resolution for recording media that do not support HD resolution. However, in this case, the copy source HD resolution program is erased, and there is a problem that viewing at the HD resolution becomes impossible.

  On the other hand, there is a problem in making it possible to copy program data without restriction due to the characteristics of digital data that image quality does not deteriorate, and it is desirable to place some restrictions on copying of program data.

  The present invention appropriately satisfies the conflicting requirements of the above-mentioned user and copyright holder, and allows a copy of another generation to be copied under a specific condition for a program for which “copy once” is set. Realize control. Accordingly, an object of the present invention is to provide an information recording / reproducing apparatus capable of improving user convenience without damaging the copyright of program data.

  In short, the present invention aims to improve the usability of the recording control apparatus.

  The above object can be achieved by the invention described in the claims.

  According to the present invention, the usability of the recording control apparatus can be improved.

The structural example of the content recording control information containing the generation control flag concerning this embodiment is shown. It is a block diagram which shows the structure of the recording control apparatus concerning this embodiment. It is a structural example of the display message which shows a recording prohibition program with respect to a user.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 6 is a diagram schematically illustrating a configuration example of the recording control apparatus according to the embodiment. Here, some of the processing functions of the recording control apparatus are the same as the processing functions of the conventional recording control apparatus, and other parts are added in the present embodiment. Each of these processing functions is realized mainly by executing a control processing program (software) according to this embodiment processed by a CPU that is a control microprocessor.

  The recording control device 1 includes an antenna 2 that receives broadcast radio waves (signals), a tuner / demodulation unit 3 that performs channel selection of received signals, signal demodulation and video signal generation, and digital data conversion and encoding of the demodulated video signals. A reception processing unit 4 that performs (for example, data compression by MPEG2 encoding), and outputs signals from the reception processing unit 4 such as an MPEG2 program stream (PS: Program Stream) or a transport stream (TS: Transport Stream). And a recording / reproduction control unit 7 for converting the data structure. The program data that can be recorded as described above is, for example, the HDD 13 and the removable HDD 14 managed by the storage management unit 10 as storage means provided in the recording control device, or a recording medium (not shown) that can be removed from the recording control device. (But not on a medium such as a DVD). The state and recording capacity of an external recording medium such as a DVD are managed by the recording medium management unit 11, and the recording capacity of the HDD 13 and the removable HDD 14 are managed by the accumulation management unit 10. The removable HDD 14 is a replaceable type of the HDD 13 and can be removed / attached from the recording control apparatus 1. Removal / attachment with respect to the recording control apparatus 1 is detected by the insertion / removal detection unit 9.

  Further, the signal output from the recording control device 1 is processed by the recording / reproduction control unit 7, the reproduction signal output 5, and the output processing unit 6. The recording / playback control unit 7 separates and extracts video and audio data from the PS or TS format signal recorded in the removable HDD 14 or the like, and the playback signal output unit 5 decodes the video signal and D / D of the decoded signal. A (digital / analog) conversion is performed. The output processing unit 6 performs output processing of video / audio signals to a television monitor or the like.

  Broadcast radio waves received by the antenna 2 are selectively extracted based on the channel selected by the tuner / demodulator 3. A user of the recording control device 1 records (records) broadcast program data of a desired channel on the removable HDD 14, for example, based on an output from the tuner / demodulator 3, or outputs from the removable HDD 14 or a recording medium. You can watch videos based on it. In general, the recording control apparatus 1 can handle an externally input signal. A user can view a signal input from the external input management unit 12 via the input terminal 15 on the TV monitor via the output / processing unit 6 from the recording / playback control unit 7 or record it on the removable HDD 14. Is possible.

  The copy control information management unit 8 is a unit that performs processing according to the present embodiment. The copy control information management means 8 extracts information related to copy control of each program from detailed information related to the program acquired by the recording / playback control unit 7 and analyzes copy control information such as “copy once”, for example. The processing related to copyright protection to be executed is executed. Specifically, for a program having copy control information as “copy once”, an instruction is recorded as to whether to record the copy control information as “copy once” or to record the copy control information as “no more copy”. / Reproduction control unit 7

  FIG. 1 shows a basic processing procedure of a recording operation for performing copy control of a program based on a generation control flag in the recording control apparatus according to the present embodiment.

  Step S101 is processing for determining whether or not the recording control apparatus is in a state of recording (recording) a program. This corresponds to the case where the user instructs recording of a specific program, or the case where the recording control apparatus automatically performs program recording based on a keyword or the like set by the user. When program recording is performed, the process proceeds to step S102, and digital copy control information relating to the recording-designated program is acquired. The digital copy control information includes various types of information describing the limit on the number of copies.

  FIG. 4 shows a description example of the digital copy control information. FIG. 4 describes four types of digital copy control information and their definitions. “Copy free” is a program that can be copied (recorded) without any restrictions. In this case, there is no limit on the number of copies. “Copy once” indicates a program that is allowed to be copied for only one generation, and a program once recorded on an HDD or the like cannot be copied to another recording medium. In general, however, movement is possible. “No more copy” is a state in which copying is not permitted any more, and corresponds to a state after a “copy once” program is recorded on the HDD or another recording medium. That is, when a conventional “copy once” program is recorded on a recording medium such as an HDD, the program is a program having digital control information of “no more copy”. “Copy never” is a program whose copy is prohibited, and cannot be recorded on a recording medium such as an HDD or a DVD. Control information related to these programs is generally carried by broadcast radio waves together with program data from a broadcasting station that performs digital broadcasting.

  Step S103 in FIG. 1 is a determination process based on the digital copy control information acquired in step S102. If it is determined in step S103 that the program is permitted to be copied, that is, if recording is to be performed on a “copy free” or “copy once” program, the process proceeds to step S104. Step S104 is processing for determining whether the designated program is “copy free” or “copy once”. If the program to be recorded is “copy free”, it is not necessary to perform copy control, and the process proceeds to step S107 to execute the recording process. When a “copy once” program is to be recorded, the process proceeds from step S104 to step S105, and the presence or absence of a generation control flag for the designated program is confirmed.

  Here, the generation control flag is a flag according to the present embodiment, and is used to control the copy generation (number of copies) of the program.

  FIG. 5 shows a configuration example of program recording control information including a generation control flag. Program recording control information describes information used when a program (content) is recorded on a storage medium, and is generally carried by broadcast waves along with program data from the broadcasting station (program copyright holder) side. Be taken. The program recording control information 500 includes a control information tag 501, a control information length 502 indicating the information length of the program recording control information, information 503 indicating whether the program may be temporarily stored, The allowable storage time 504 of programs that are allowed to be stored in a normal manner is included. The generation control flag 505 is information for program generation management used in the present embodiment. By switching ON / OFF of the generation control flag 505 (for example, 1 and 0 indicate ON and OFF), generation management at the time of program recording can be easily realized on the recording control device side. In the present embodiment, the generation control information is described as a flag, but the information format is not limited to this.

  In step S105 in FIG. 1, if the generation control flag is not set for the designated program, the process proceeds to step S108, and the copy control information of the recording destination for the designated program is changed from “copy once” to “no more copy” ( Update. As a result, as in the conventional copy control, it is possible to make a state in which subsequent recording cannot be performed for the recorded program. For example, when a broadcast program is recorded on the removable HDD 14 of FIG. 6, the copy control information of the recorded program is recorded and held as “no more copy”. In this case, the program can be moved from the removable HDD 14 to the HDD 13 or the like, but the program cannot be copied. Even when there is a recording control apparatus that cannot recognize the generation control flag, it is possible to perform conventional processing in step S108.

  On the other hand, if the generation control flag is set in step S105, the process proceeds to step S106. In step S106, the copy control information is not changed (updated), and the program of “copy once” is set as “copy once” again and is recorded and held in a removable HDD as a recording destination. As a result, the program that has been copied (program recording) in step S107 after step S106 can be copied from the recording destination to another recording medium by another generation. For example, when a broadcast program is recorded on the removable HDD 14 in FIG. 6, the program can be copied again to a recording medium such as a DVD managed by the recording medium management unit 11.

  For a program having digital copy control information of “copy never”, that is, a program determined to be unrecordable in step S103, the user is notified in step S109 that the program cannot be recorded, and the process is terminated. In this case, program recording is not executed. Note that the notification to the user in step S109 is performed, for example, by displaying a warning message on a television monitor.

  FIG. 7 shows a display example of a warning message regarding a recording prohibited program. In the display message 700, for example, a warning message stating that “the designated program cannot be recorded (copied)” is displayed, and information 701 such as the program name and broadcast date / time of the designated program is displayed. Yes. Further, by displaying a confirmation message “Do you want to record another program?” And selection buttons “Yes” 702 and “No” 703 for selecting an operation, another program is displayed to the user. Can be prompted to record. If there is no response from the user, the message may be automatically deleted after the display for a certain time. The message configuration is not limited to this.

  As described above, according to the configuration of the present embodiment, it is possible to perform appropriate copy control for a program for which “copy once” is set. As a result, it is convenient for the user, and program recording with copyright protection can be performed in a manner that reflects the intention of the broadcast station, that is, the program copyright holder. Note that the order and configuration of the processing shown in FIG. 1 are not limited to this. For example, the determination in step S105 may be configured to shift to step S108 when the generation control flag is set. Further, the notification to the user in step S109 is not limited to the message display on the TV monitor, and various notification methods such as notification by warning sound, LED blinking, and e-mail transmission to the mobile phone can be taken.

  FIG. 2 shows a processing procedure of a recording operation for performing copy control at the time of broadcast reception based on the generation control flag in the recording control apparatus according to the present embodiment. The same functional parts as those in FIG. 1 are denoted by the same reference numerals, and the description thereof is omitted unless particularly necessary. 2 is different from FIG. 1 in the process of determining whether or not the broadcast is directly received in step S203.

  Step S201 is a process for determining whether or not program recording or program copying is designated. Here, the program copy mainly means that a program once recorded is copied (duplicated) to another recording medium. For example, a “copy once” program recorded in a removable HDD is recorded in another recording medium. This corresponds to the case of copying to a medium.

  In step S202, it is determined whether or not recording or copying is possible for a program for which recording or copying is instructed. If the program recording / copying is not permitted, the user is notified in step S205 and the recording / copying process is terminated. If program recording / copying is possible, the process proceeds from step S202 to step S104 to determine whether the designated program is a program having digital copy control information of “copy once”.

Step S203 is a process for determining whether to directly record the broadcast received by the recording control apparatus or to record / copy the program data other than the broadcast.
In this embodiment, the recording control apparatus controls to record and hold the copy control information of the recording destination as “copy once” only for the “copy once” program received via the antenna 2 or the tuner / demodulator 3. It is characterized by that. That is, if direct broadcast recording is instructed, the process proceeds from step S203 to step 105 and step S106, and the copy control information of the program recording destination is processed as “copy once”.

  If it is determined in step S203 that the broadcast is not directly received, the process proceeds to step S108, and the copy control information of the program at the recording destination is recorded as “no more copy”. In this case, copying cannot be performed from the recording destination to another recording destination. Step S206 provided before step S108 is a process for clearly indicating to the user that copying cannot be performed from the recording destination and prompting the user to be alerted. The process is similar to the message screen shown in FIG. Can do. Note that the case where the broadcast is not received directly means that, for example, a program recorded on a storage medium such as a removable HDD is copied to another recording medium or input from the outside of the recording control apparatus via the external input management unit 12 This corresponds to a case where the digital signal (program data) recorded is recorded on a removable HDD or an external recording medium.

  As described above, the configuration of the embodiment shown in FIG. 2 makes it possible to record the copy control information as “copy once” only when receiving program data transmitted from a broadcasting station or the like. As a result, the recording data of the broadcast program received by the recording control device can be copied to another recording medium, the inconvenience in handling the recorded program, which has been a problem, can be eliminated, and the recording medium Conventionally, digital copy control can be performed for secondary use of program data such as program copy between.

  FIG. 3 shows a processing procedure of a recording operation for performing copy control of a program on the basis of the recording availability information of the recording destination in the recording control apparatus according to the present embodiment. The same functional parts as those in FIG. 1 are denoted by the same reference numerals, and the description thereof is omitted unless particularly necessary.

  If recording is possible in step S103, it is determined in step S301 whether the program recording destination is in a recordable state. If the recording is possible, nothing is performed and the process proceeds to the “copy once” determination in step S104.

  When the recording destination is in an unrecordable state, specifically, when the removable HDD 14 designated as the recording destination is removed from the recording control device, or the recording destination medium records the designated program. If the remaining capacity is not sufficient, the process proceeds from step S301 to step S302 to determine whether or not to change the recording destination. Whether or not to make a change may be confirmed by confirming the change with a confirmation message or the like to the user, or may be determined in advance by the user as a setting of the recording control apparatus. If the recording destination is not changed in step S302, it is determined that the designated program cannot be recorded, and the process is terminated via step S109.

  When the change of the recording destination is selected, the process proceeds from step S302 to step S303, and the generation maintenance mode is set. At this time, the recording destination is changed by the recording / reproduction control unit 7 selecting an appropriate recording destination based on the information on the storage recording medium managed by the storage management unit 10 and the recording medium management unit 11. Can do. For example, when the removable HDD 14 set as the recording destination is in a state where recording is not possible, a process of performing alternative recording on the HDD 13 is performed.

  Step S304 is processing for determining the generation maintenance mode set in step S303. “Generation maintenance mode” is a mode provided to perform the same processing as the generation control flag in FIG. 1 and FIG. 2, but it is not a form of receiving from a broadcast signal, and can be freely set inside the recording control device Information. If the generation maintenance mode is valid, the process of step S106 is performed. If the generation maintenance mode is invalid, the process branches to perform the process of step S108. That is, only when the program recording destination is changed in step S302, the program recording to the recording destination is executed while maintaining the copy control information of “copy once” in step S106 and step S107. After completion of the recording process in step S107, the generation maintaining mode is canceled in step S305, and the process ends. Note that the order and configuration of the processing shown in FIG. 3 are not limited to this. For example, when the recording destination is not changed in S302, a configuration is adopted in which a part of the program is recorded by the capacity that can be recorded. Is also possible.

  As described above, with the configuration of the embodiment shown in FIG. 3, when the recording destination cannot be recorded, a program having copy control information of “copy once” with respect to the alternative recording destination is recorded while maintaining the “copy once” generation. It becomes possible to do. As a result, when a program is recorded to a recording destination that is not intended by the user, the recorded program can be copied to another recording destination for one generation only, improving user convenience. It becomes possible to make it.

  As described above, in each embodiment, the HDD 13 and the removable HDD 14 are described as examples of the storage medium. However, the storage medium is not limited to this, and for example, a configuration in which a plurality of removable HDDs are mounted in the recording control apparatus may be employed. Absent. Further, the case where the generation control flag is used has been mainly described. However, for example, the confirmation of the presence / absence of the generation control flag performed in step S105 in FIG. 2 is omitted. It is also possible to adopt an embodiment in which a program is recorded on a recording destination as “copy once” shown in FIG. Although broadcast reception has been described, broadcast transmission means is not limited to radio waves, and transmission using, for example, IP packets can also be used.

  Another embodiment is a recording apparatus for recording program information, a recording unit for recording program information, and a copy for managing copy control information added to the program information and information relating to a copy of the program information A control information management unit and a predetermined condition when the copy control information managed by the copy control information management unit is copy-once (for example, a flag added to program information (if there is a flag related to generation control, a program information recording unit) The program information is not recorded as re-copy prohibited, and when there is no generation control flag, the program information is recorded as re-copy prohibited in the recording unit), the program information input source (the input source is broadcast receiving means) When the input source is not broadcast receiving means, the program information is controlled not to be recorded in the recording unit as being prohibited from being copied again. Control whether to record the program information in the recording unit as re-copying prohibition based on whether or not the recording can be recorded on the recording medium designated by the user). And a recording device having a unit. As another embodiment, an external recording medium can be mounted and a recording apparatus for recording program information, which manages copy control information added to the program information and information relating to copying of the program information. A copy control information management unit that performs a predetermined condition when the copy control information managed by the copy control information management unit is copy-once (for example, a flag added to the program information and the program information as in the other embodiments described above) And a control unit that controls whether or not the program information is recorded on the external recording medium as being prohibited from being copied again, based on the input source and whether or not the recording can be performed on the recording medium designated by the user. Conceivable.

As described above, by performing appropriate copy control for a program for which “Copy Once” is set, program recording is easy for the user and does not impair copyright for the program copyright holder. It can be performed. Further, by maintaining the copy generation information only when receiving a program transmitted from a broadcasting station or the like, it is possible to perform conventional copy control for secondary use of program data.
