At that time, the advertisement section may be skipped or fast-forwarded by the operation of the user (viewer).

JP 2008-199674 A

  An object of the present technology is to enable appropriate reproduction of a reproduction-restricted section when storing and reproducing program content including a reproduction-restricted section such as an advertisement section.

The concept of this technology is
A playback unit that plays back program content including a playback restriction section from the storage unit;
The content reproducing apparatus includes a control unit for restricting a reproducing operation of the reproducing unit so that the reproduction restriction section is normally reproduced when the reproduction restriction of the reproduction restriction section is not released.

  In the present technology, the reproduction unit reproduces the program content including the reproduction restriction section from the storage unit. For example, the storage unit may be configured by an external device connected via the Internet or a home network, in addition to the case where the content reproduction apparatus itself has the storage unit. For example, in addition to the advertisement (CM) section, the playback restriction section includes a warning section for giving a warning when viewing program content, a program promotion section for promoting another program, and a program main section. Also includes a section where the production side desires to view in normal reproduction.

  For example, the information processing apparatus further includes a receiving unit that receives the program content together with information indicating the playback restriction section or information for acquiring the information, and a storage control unit that stores the received program content in the storage unit. Is also good. In this case, it is possible to accurately recognize the playback restricted section in the program content. Further, the receiving unit may be configured to further receive information for releasing the restriction on the reproduction restriction section or information for acquiring the information. For example, the information for releasing the restriction includes the number of times the CM is skipped in which the CM skip / fast-forward does not need to be restricted, the time limit in which the CM skip / fast-forward is restricted, and the like.

  When the control of the reproduction restriction section has not been released by the control section, the reproduction operation of the reproduction section is restricted so that the reproduction restriction section is normally reproduced. For example, when the playback unit plays back the program content from the storage unit, the playback unit may limit the playback operation of the playback unit so that the playback-restricted section is normally played before the playback limit expires. Good. Then, in this case, for example, the control unit does not limit the reproduction operation of the reproduction unit when the reproduction restriction section has already been normally reproduced the predetermined number of times even before the time limit of the reproduction restriction. And so on.

  Also, in this case, for example, the playback restriction section is an advertisement section, and when the advertisement section of the program content is normally reproduced before the time limit of the reproduction restriction, an external advertisement rating measurement server is accessed to register the rating. A communication unit may be further provided. In this case, the advertisement audience rating server can perform highly accurate audience rating measurement.

  In this case, for example, the playback restriction section is an advertisement period, and when the advertisement section of the program content is normally played before the time limit of the reproduction restriction, a price granting section that gives the viewer a price for viewing the advertisement section. May be further provided. For example, the consideration giving unit may access the external point server to give points to the viewer. By giving a value to the viewer in this way, the viewer can be encouraged to view the advertisement section.

  In this case, for example, the playback restriction section is an advertisement section, and when the playback section plays back the advertisement section of the program content, the normal playback of the advertisement period is performed even after the playback restriction time limit or before the playback restriction time limit. When the number of times is equal to or more than the predetermined number, a communication unit that accesses an external advertisement providing server to acquire a replacement advertisement may be further provided. By obtaining the replacement advertisement in this way, it is possible to increase the added value of the advertisement.

  Further, for example, when the playback unit plays back the program content from the storage unit, if the number of normal playbacks of the playback limited section included in the program content is less than a predetermined number, the playback limited section performs the normal playback. To limit the reproducing operation of the reproducing unit.

  In this case, for example, the playback restriction section is an advertisement section, and when the playback section plays back the advertisement section of the program content, if the normal playback number of this advertisement section is a predetermined number or more, the playback section accesses the external advertisement providing server. And a communication unit that acquires the replacement advertisement. By obtaining the replacement advertisement in this way, it is possible to increase the added value of the advertisement.

  Also, in this case, for example, the playback restriction section is an advertisement section, and when the playback section plays back the advertisement section of the program content, when a certain period has elapsed since the storage in the storage section, an external advertisement is provided. The communication device may further include a communication unit that accesses the server and acquires the replacement advertisement. By obtaining the replacement advertisement in this way, it is possible to increase the added value of the advertisement.

  In this case, for example, the playback restriction section is an advertisement section, and further includes a communication unit that notifies an external server that the advertisement section has been normally played when the advertisement section of the program content is normally played. It may be done.

  As described above, in the present technology, when the reproduction restriction of the reproduction restriction section is not released, the reproduction operation of the reproduction unit is restricted so that the reproduction restriction section is normally reproduced. Therefore, appropriate reproduction of the reproduction restricted section can be performed.

  In the present technology, for example, in a state where the playback unit is playing back a playback restriction section, when there is a request for skip or fast forward by a viewer operation, when the playback restriction of this playback restriction section is not released And a notifying unit that notifies the viewer that the request cannot be satisfied. In this case, the user can easily know that he cannot respond to the skip or fast-forward request.

Another concept of the present technology is
A program content acquisition unit for acquiring program content including a playback restriction section,
The content transmitting apparatus includes a transmitting unit that transmits the program content together with information indicating the reproduction restriction section or information for acquiring the information.

  In the present technology, the program content acquisition section acquires the program content including the playback restricted section. The transmission unit transmits the program content together with information indicating the playback restriction section or information for acquiring the information. For example, the transmission unit may be configured to further transmit information for releasing the restriction on the reproduction restriction section or information for acquiring the information.

  As described above, in the present technology, the program content is transmitted together with the information indicating the reproduction restricted section or the information for acquiring the information. Therefore, on the receiving side, it is possible to accurately recognize the reproduction restricted section in the program content and to restrict the reproduction operation of the reproducing unit to the reproduction restricted section correctly.

  According to the present technology, it is possible to appropriately reproduce a reproduction-restricted section when storing and reproducing program content including a reproduction-restricted section such as an advertisement section. It should be noted that the effects described in this specification are merely examples and are not limited, and may have additional effects.

Hereinafter, embodiments for carrying out the invention (hereinafter, referred to as “embodiments”) will be described. The description will be made in the following order.
1. Embodiment 2. Modified example

<1. Embodiment>
[Configuration example of transmission / reception system]
FIG. 1 shows a configuration example of the transmission / reception system 10. In the transmission / reception system 10, a broadcast transmission system 100 and a program providing server (distribution server) 200 are arranged on the transmission side, and a content reproduction device 300 is arranged on the reception side. The program providing server 200 is connected to the content reproduction device 300 through a communication network 400 such as the Internet.

  On the receiving side, the television receiver 510 or the portable terminal 520 is connected to the content reproducing apparatus 300. The content reproduction device 300 and the television receiver 510 or the portable terminal 520 are connected by wire or wirelessly. In the illustrated example, the content reproduction apparatus 300 is provided separately from the television receiver 510 and the mobile terminal 520. However, a configuration in which the television receiver 510 and the mobile terminal 520 have the function of the content reproduction apparatus 300 is also available. Conceivable.

  The content reproduction device 300 is connected to various servers via the communication network 400. As various servers, there are a content usage control server 610, an advertisement audience rating measurement server 620, a point server 630, an advertisement providing server 640, a user information management server 650, a content usage history management server 660, and the like. Note that a plurality of these servers may be collectively configured as one server.

  The broadcast transmission system 100 broadcasts program contents including an advertisement section (hereinafter, appropriately referred to as a “CM section”) as a reproduction restriction section to a receiving side. The program providing server 200 transmits the program content including the CM section to the receiving side by communication. The broadcast transmission system 100 and the program providing server 200 include, for example, a program content acquisition unit that acquires program content from a storage or the like, and a transmission unit that transmits the program content. The broadcast transmission system 100 and the program providing server 200 transmit various information related to the program content together with the program content. In this case, various information is embedded in the program content.

The various information related to the program content includes, for example, the following information. Here, the information of (3) forms information indicating a CM section. Further, the information of (4) and (5) constitutes information for releasing the restriction of the CM section.
(1) ID capable of specifying program content
(2) ID that can identify CM
(3) Start time and end time in the content of each CM (4) Time limit during which CM skip / fast-forward is restricted (5) Number of times CM is played without restrictions on CM skip / fast-forward (6) Each server (cloud server) ) URL

  FIG. 2 shows an example of a data structure in a new descriptor (descriptor) included in the PMT of the MPEG2-TS or in a new box of the MP4. The field of “content_id” indicates an ID capable of specifying the program content. The “restriction_expiration_date” field indicates a time limit during which CM skip / fast-forward is restricted. Although the date “date” at which the restriction is released is shown here, it is also conceivable that it indicates the time from the recording to the release of the restriction.

  The “restriction_expiration_count” field indicates the number of times a CM has been reproduced for which no restriction is required for skipping / fast-forwarding the CM. The field of “pb_history_server_url” indicates the URL of the content use history server. The “ad_pgm_count” field indicates the number of CMs (CM sections) in the program content.

  Each field of “ad_pgm_id”, “ad_pgm_start_time”, “ad_pgm_end_time”, and “ad_pgm_server_url” repeatedly exists for the number of CMs. The “ad_pgm_id” field indicates an ID that can specify a CM. The “ad_pgm_start_time” field indicates the start time of the CM in the program content. The “ad_pgm_end_time” field indicates the end time of the CM in the program content. The field of “ad_pgm_server_url” indicates the URL of the advertisement providing server.

  The structure of the PMT is stipulated in the MPEG-2 Systems standard (ISO / IEC 13818-1), and in the case of Japanese broadcasting, ARIB standard: STD-B10. The box structure of MP4 is defined in ISO / IEC 14496-12.

  Note that instead of providing a part of the above-described various kinds of information together with the program content to the content reproduction apparatus 300, a server (cloud server) connected to the communication network 400 may provide the content reproduction apparatus 300. Depending on the information, both of them may be provided to the content reproducing apparatus 300. For example, an operation in which dynamic control is performed by overwriting information in program content with information of a cloud server is also conceivable.

  For example, it is conceivable that the information of (2)-(5) is provided from the cloud server to the content reproduction device 300. In that case, the content reproduction device 300 sends, for example, the information of (1) to the cloud server and acquires the information of (2)-(5) of each CM section included in the program content. In this case, the information of (1) constitutes information for acquiring the information of (2)-(5).

  Here, an example of a method of embedding the above various information in the program content will be described. For example, in a stream of the MPEG2-TS format, a descriptor (descriptor) stored in an existing program map table (PMT) is replaced with an ARIB (Association of Radio Industries and Business) or NextTV-F (Next Generation Television & Broadcasting Promotion Forum) may be newly defined, and its descriptor may include a field group carrying the above information.

  For example, in a file in MP4 format, a new box stored in an existing move box (moov box) or a move box (moof box) is similarly defined, and the above information is stored in the new box. A method of including a field group to carry is conceivable.

  The content reproducing device 300 receives the program content transmitted from the broadcast transmission system 100 or the program providing server 200. This program content includes the CM section as described above. As described above, various information is sent to the content reproduction device 300 together with the program content from the broadcast transmission system 100 or the program providing server 200.

  The content reproduction device 300 transmits the program content received from the broadcast transmission system 100 or the program providing server 200 to the television receiver 510 or the portable terminal 520 as it is, or accumulates it in the accumulation unit. In addition, the data may be transmitted to the television receiver 510 or the portable terminal 520 and may be stored in the storage unit. The content reproduction device 300 reproduces the program content stored in the storage unit at an appropriate timing by a user operation and transmits the program content to the television receiver 510 or the portable terminal 520.

  Here, the storage unit may be provided by the content reproduction apparatus 300 itself, or may be configured by a server connected to the communication network 400 on the cloud (for example, the program providing server 200). When the storage unit is configured by a server on the cloud, the content reproduction device 300 transmits the program content received from the broadcast transmission system 100 or the program providing server 200 to the server via the communication network 400 and stores the program content. However, the server in which the program content is stored is arranged on the cloud, the content reproduction device 300 virtually executes the storage operation, and the reproduction of the program that has been virtually stored is performed by the server on the cloud. , Via the communication network 400 and display. In this case, it is conceivable that the URL for the program on the server where the program content is stored is also included in the new descriptor included in the PMT of the MPEG2-TS or the new box of MP4.

  In addition, the content reproduction device 300 stores, in a storage unit, various information received together with the program content from the broadcast transmission system 100 or the program providing server 200, and various information obtained from the cloud server, and appropriately uses the information. I do.

  FIG. 3 shows a configuration example of the content reproduction device 300. The content reproduction device 300 includes a control unit 301, a storage unit 302, a digital tuner 303, a communication unit 304, a storage unit 305, an output unit 306, a user operation unit 307, and a display unit 308. .

  The control unit 301 includes a CPU and controls the operation of each unit of the content reproduction device 300. The storage unit 302 includes a ROM that stores control software and data, a RAM that forms a work area of the CPU, and the like. The user operation unit 307 is a part for the user to perform various operations. The display unit 308 performs a display of the status of the content reproduction device 300, display for convenience of user operation, and the like. The user operation unit 307 and the display unit 308 constitute a user interface unit.

  The digital tuner 303 receives a program content transmitted from the broadcast transmission system 100 by broadcasting. The communication unit 304 communicates with a server (cloud server) connected to the communication network 400. The communication unit 304 receives program contents distributed from the program providing server 200.

  The storage unit 305 is configured by, for example, an HDD (Hard Disk Drive). The storage unit 305 stores program content received by the digital tuner 303 and the communication unit 304 under the control of the control unit 301 based on a user operation. Further, the storage unit 305 reproduces the stored program content at an appropriate timing under the control of the control unit 301 based on a user operation. In this sense, the storage unit 305 also constitutes a playback unit.

  Note that the program content received by the digital tuner 303 or the communication unit 304 may be stored in a server on the cloud. In this case, the program content received by the digital tuner 303 or the communication unit 304 is transmitted to the server via the communication unit 304 and accumulated. However, as described above, this storage operation may be virtualized by arranging the program content on a server on the cloud in advance. In this case, under the control of the control unit 301 based on a user operation, the program content is reproduced from the server at an appropriate timing.

  The output unit 306 stores the program content received by the digital tuner 303 or the communication unit 304 or the program content reproduced by the storage unit 305 (the program content is stored in a server on the cloud) under the control of the control unit 301 based on the user operation. In this case, the program content (reproduced from the server) is selectively sent to the television receiver 510 or the portable terminal 520.

  When reproducing the program content and transmitting it to the television receiver 510 or the portable terminal 520, the content reproduction device 300 reproduces the CM section for which the reproduction restriction has not been released at the normal speed (hereinafter referred to as “normal reproduction” as appropriate). "). For example, even if there is a request for a specific operation such as skip or fast-forward by a user operation in a state where normal reproduction is being performed in this CM section, the request is not accepted.

  In this case, for example, for the user's convenience, the content reproduction device 300 notifies the user by not displaying a request for a specific operation such as skipping or fast-forwarding by image display or audio output. FIG. 4 illustrates an example of a notification display displayed on the display unit 308.

  The content reproduction device 300 determines release of the reproduction restriction based on information on the number of times of normal reproduction (see the “restriction_expiration_count” field in FIG. 2) or the expiration date (see the “restriction_expiration_date” field in FIG. 2). It is also conceivable to use both the time limit and the number of times.

  For example, for a CM section for which normal reproduction has been performed a predetermined number of times, a request for a specific operation such as skip or fast-forward during normal reproduction of the CM section is accepted. For example, for a CM section whose expiration date has passed, a request for a specific operation such as skip or fast-forward during normal reproduction of the CM section is accepted. In addition, a request for the specific operation is received for a CM section in which normal reproduction has been performed a predetermined number of times even before the time limit by using the time limit and the number of times. Here, as the information on the predetermined number of times and the time limit, a value transmitted together with the program content as described above, or a value predetermined in the regulation of broadcast / distribution is used.

  When the reproduction restriction is canceled based on the information on the number of times of normal reproduction, the content reproduction device 300 stores the value obtained by counting the number of times of reproduction of the CM section when the CM section is normally reproduced from the start time to the end time. As a method of managing the reproduction history of the CM section of the program content, as shown in FIG. 5, a table of the start time, the end time, and the number of times of reproduction is held for each CM section, and the number of times of reproduction is normally performed for the part that is normally reproduced Can be recorded. Here, the storage location of the table may be in the server on the home network or in the content usage history management server 660 on the cloud, in addition to being stored in the content reproduction device 300.

  The flowchart in FIG. 6 illustrates an example of the playback operation of the content playback device 300. The content reproduction device 300 starts processing in step ST1. Then, in step ST2, normal reproduction of the program content is started. Next, in step ST3, the content reproduction device 300 checks the current reproduction position.

  Next, in step ST4, it is determined whether or not the CM section is being reproduced. When determining that the CM section is being reproduced, the content reproduction device 300 sets a CM section flag in step ST5.

  Next, in step ST6, the content reproduction device 300 determines whether skip or fast-forward has been requested. When determining that skip or fast-forward is requested, in step ST7, the content reproduction device 300 determines whether the number of times of reproduction of this CM section is less than a predetermined required number of times.

  When determining that the number is less than the predetermined required number, the content reproduction device 300 notifies the user (viewer) in step ST8 that the request cannot be satisfied. This notification is performed by, for example, image display (see FIG. 4) or audio output, as described above. After the process of step ST8, the content reproduction device 300 moves to the process of step ST13.

  If it is determined in step ST7 that the number is not less than the required number of times, that is, the number is equal to or more than the required number of times, in step ST9, the content reproducing apparatus 300 performs the requested skip or fast forward. After the process of step ST9, the content reproduction device 300 moves to the process of step ST13.

  When determining in step ST4 that the CM section is not being played, the content reproduction device 300 determines whether or not the CM section flag is set in step ST10. When judging that the CM section flag is set, in step ST11, the content reproduction device 300 increments the number of times of reproduction of this CM section, that is, increments the number by "+1". Next, in step ST12, the content device 300 resets the CM section flag. After the process of step ST12, the content reproduction device 300 proceeds to the process of step ST13.

  When it is determined in step ST6 that neither skip nor fast-forward is requested, or when it is determined in step ST10 that the CM section flag is not set, the content reproduction device 300 immediately proceeds to the process of step ST13.

  In step ST13, the content reproduction device 300 determines whether or not a stop of the normal reproduction has been requested. When judging that the stop of the normal reproduction is not requested, the content reproduction device 300 returns to the process of step ST3, and repeats the same process as described above. On the other hand, when judging that the stop of the normal reproduction has been requested, the content reproduction apparatus 300 ends the reproduction processing in step ST15.

  In addition, as shown in FIG. 7, when playback is performed after jumping from a position A in the program content to a temporally future position B (B0, B1, B2, B3), the start time is in the range from the position A to the position B. If there is a CM section (X1, X2) inside, and the CM section has not been reproduced a predetermined number of times, it is conceivable that the CM section is normally reproduced and then reproduced from position B. It is conceivable that the CM section to be reproduced here is only a CM section having a start time immediately before the position B. If the position B is within the range of the CM section, the position B is reset to the position immediately after the CM section.

Here, “jump from position A to position B” means that normal reproduction is started after moving from position A to position B by a method other than normal reproduction, and specifically, Case.
(1) Normal reproduction is performed after the position A is reached from the position A by fast forward.
(2) Normal playback is performed after the seek bar is moved from position A to position B.
(3) A chapter selection operation starting from position A to position B is performed, and normal reproduction is started.

  The flowchart in FIG. 8 shows an example of the playback operation of the content playback device 300 at the time of this jump. The content reproduction device 300 starts processing in step ST21. Then, in step ST22, the reproduction position is set to position B. Next, in step ST23, the content reproduction device 300 determines whether or not the start position of the CM section is included between the position A and the position B.

  When determining that the start position of the CM section is included, in step ST24, the content reproduction device 300 specifies the CM section X having the latest start position retroactively from the position B. Next, in step ST25, the content reproduction device 300 determines whether the number of times of reproduction of the CM section X is less than a predetermined required number of times.

  When determining that the number is less than the predetermined required number, the content reproducing device 300 determines whether or not the position B is within the range of the CM section X in step ST26. When determining that the position B is within the range of the CM section X, the content reproduction device 300 changes the position B to the end time of the CM section X in step ST27. After the process of step ST27, the content reproducing device 300 proceeds to a process of step ST28. If it is determined in step ST26 that the position B is not within the range of the CM section X, the content reproduction device 300 immediately proceeds to the process of step ST28.

  In step ST28, the content reproduction device 300 sets the reproduction position to the start position of the CM section X. Next, in step ST29, the content reproduction device 300 starts normal reproduction. Next, in step ST30, the content reproduction device 300 determines whether or not the CM section X is being reproduced.

  When determining that the CM section X is being reproduced, the content reproduction device 300 determines whether skip or fast-forward is requested in step ST31. When determining that skip or fast-forward has been requested, the content reproduction device 300 notifies the user in step ST32 that the request cannot be satisfied.

  After the process of step ST32, the content reproduction device 300 returns to the process of step ST30, and repeats the same process as described above. When it is determined in step ST31 that neither skip nor fast-forward is requested, the content reproduction device 300 immediately returns to the process in step ST30.

  If it is determined in step ST30 that the CM section X is not being reproduced, the content reproduction device 300 proceeds to the process of step ST33. In this step ST33, the content reproduction device 300 increments the number of times of reproduction of this CM section X, that is, increments it by “+1”. Next, the content device 300 sets the reproduction position to the position B in step ST34.

  After the process of step ST34, the content reproducing device 300 proceeds to a process of step ST35. If it is determined in step ST23 that the start position of the CM section is not included, the content reproduction device 300 immediately proceeds to the process of step ST35. In step ST35, the content reproduction device 300 starts normal reproduction.

  After step ST35, the content reproduction device 300 ends the process at the time of jump in step ST36. Thereafter, the content reproduction device 300 performs the reproduction operation shown in the flowchart of FIG.

  Further, as shown in FIG. 9, when the playback is performed after jumping from the position A in the program content to the position C (C0, C1, C2) in the past in time, the CM having the latest start time retroactively from the position C It is also conceivable to perform reproduction from position C after reproducing the section.

  FIG. 10 shows an example of the playback operation of the content playback device 300 at the time of this jump. The content reproduction device 300 starts processing in step ST41. Then, in step ST42, the reproduction position is set to the position C. Next, in step ST43, the content reproducing device 300 determines whether or not there is a CM section having a start position immediately before the position C.

  When determining that there is a CM section, in step ST44, the content reproduction device 300 specifies a CM section Y having a start position immediately before the position C. Next, in step ST45, the content reproduction device 300 determines whether the number of times of reproduction in the CM section Y is less than a predetermined required number of times.

  When determining that the number is less than the predetermined required number, the content reproduction device 300 determines whether or not the position C is within the range of the CM section Y in step ST46. When determining that the position C is within the range of the CM section Y, the content reproduction device 300 changes the position C to the end time of the CM section Y in step ST47. After the process of step ST47, the content reproducing device 300 proceeds to a process of step ST48. If it is determined in step ST46 that the position C is not within the range of the CM section Y, the content reproduction device 300 immediately proceeds to the processing of step ST48.

  In step ST48, the content reproduction device 300 sets the reproduction position to the start position of the CM section Y. Next, in step ST49, the content reproduction device 300 starts normal reproduction. Next, in step ST50, the content reproduction device 300 determines whether or not the CM section Y is being reproduced.

  When determining that the CM section Y is being reproduced, the content reproduction device 300 determines in step ST51 whether skip or fast-forward is requested. When determining that skip or fast-forward has been requested, the content reproduction device 300 notifies the user in step ST52 that the request cannot be satisfied.

  After the process of step ST52, the content reproducing device 300 returns to the process of step ST50 and repeats the same process as described above. If it is determined in step ST51 that neither skip nor fast-forward is requested, the content reproduction device 300 immediately returns to the process in step ST50.

  If it is determined in step ST50 that the CM section Y is not being reproduced, the content reproduction device 300 proceeds to the process of step ST53. In step ST53, the content reproduction device 300 increments the number of times of reproduction in the CM section Y, that is, increments the number by “+1”. Next, the content device 300 sets the reproduction position to the position C in step ST54.

  After the process of step ST54, the content reproduction device 300 proceeds to a process of step ST55. If it is determined in step ST43 that the start position of the CM section is not included, the content reproduction device 300 immediately proceeds to the process of step ST55. In this step ST55, the content reproduction device 300 starts normal reproduction.

  After step ST55, the content reproduction device 300 ends the process at the time of jump in step ST56. Thereafter, the content reproduction device 300 performs the reproduction operation shown in the flowchart of FIG.

It is also conceivable to limit the reproduction of the CM section described above to the following cases (see FIG. 11).
(1) If the result d1 of subtracting the end time of the CM section Y from the time of the position C is equal to or less than a predetermined value T1, and / or the time of the position C from the start time of the nearest CM section Z in the future direction from the position C When the subtraction result d2 is equal to or greater than a predetermined value T2.
(2) When the result d1 obtained by subtracting the end time of the CM section Y from the time of the position C is equal to or less than a predetermined value T1, and / or the result d3 obtained by subtracting the time of the position C from the time of the position A is equal to or more than a predetermined value T3. Case.
(3) When the ratio of d1 to d1 + d2 is equal to or less than a predetermined value.

This is represented by the following equation.
Case 1) IF (d1 <T1) THEN "Play CM section Y"
Case 2) IF (d2> T2) THEN "Play CM section Y"
Case 3) IF (d3> T3) THEN "Play CM section Y"
Case 4) IF ((d1 <T1) and (d2> T2)) THEN "Play CM section Y"
Case 5) IF ((d1 <T1) and (d3> T3)) THEN "Play CM section Y"
Case 6) IF (d1 / (d1 + d2) <P) THEN "Play CM section Y"

  The flowchart in FIG. 12 illustrates an example of a playback operation of the content playback device 300 when the above-described limitation is performed. In this case, the processing of step ST60 is newly added between step ST44 and step ST45 with respect to the reproducing operation of the flowchart of FIG. In step ST60, the content reproduction device 300 determines whether or not the limitation requirement (any of cases 1 to 6) is satisfied, and proceeds to the process of step ST45 only when the requirement is satisfied. The rest of the reproducing operation of the flowchart of FIG. 12 is the same as the reproducing operation of the flowchart of FIG.

  When a program being broadcast or streamed is displayed on a display device such as the television receiver 510, the number of times of reproduction may be counted for the displayed CM section. For example, for a program whose broadcast has been received and displayed by the television receiver 510, the content usage history management server 660 on the cloud counts the number of times of playback, and the content playback device 300 refers to the history at the time of recording and playback of the same program. It can be reflected in the reproduction of

  Further, it is conceivable that fast-forward / rewind at a speed higher than a predetermined speed is not limited including the CM section. In addition, it is conceivable that editing such as deletion is prohibited for a CM section in which the number of times of reproduction is less than a predetermined value. On the other hand, it is conceivable to control such that the CM section in which the number of times of reproduction reaches a predetermined value is not automatically reproduced or deleted automatically.

  The number of times that the reproduction restriction of the CM section is required may be set to an extremely large value or unlimited depending on the program content. However, the number of times that each user (viewer) plays a CM section is counted by a server on the cloud, and is required when the total number reaches a predetermined value or when a small number of times is set due to rebroadcasting or the like. It is conceivable that the number of times of reproduction is changed.

  In this case, the content playback device 300 accesses the content usage control server 610 that manages the required number of times of playback directly or via the content usage history management server 660, and based on the result, restricts the playback restriction of the CM section of the program content. It is conceivable to determine the necessity. In this case, when the content reproduction device 300 of each user (viewer) performs normal reproduction of the CM section, the content reproduction device 300 notifies the cloud server that performs the totalization as described above.

  As for the reproduction of the CM section, in addition to reproducing the contents recorded in the storage unit (the storage unit in the content reproduction device 300 or on the cloud), the CM which is streamed or downloaded via the communication network 400 is also reproduced. It is possible to play.

  When selecting what is to be reproduced, it is conceivable to refer to and use the usage history of program content and / or various information related to the user. For example, it is conceivable to change the content of the CM based on the number of times the CM section has been reproduced. Specifically, for example, if not reproduced, the recorded CM is reproduced, and if reproduced, the ID of the recorded CM is sent to the advertisement providing server 640, the URL of the replacement CM is received, and the CM is transmitted from the URL. It is conceivable to acquire and play.

  Further, for example, it is conceivable to replace the CM with the latest CM prepared by the sponsor based on the reproduction date and time. Specifically, for example, after a lapse of a predetermined period from the recording date or after the time limit transmitted as broadcast / distribution metadata, the ID of the recorded CM is transmitted to the advertisement providing server 640, and the URL of the replacement CM is transmitted. It is conceivable to receive and play back a CM from the URL.

  Also, for example, user attribute information (age, gender, nationality, address, etc.), information reflecting tastes (playback / viewing / reservation / storage history of programs, etc.), and access history to CM information (together with CM) Based on detailed information broadcasted / distributed, browsing status of URL destination sites, etc.), and user feedback on CMs (like / dislike, required / unnecessary, purchased), replace with CMs that are likely to match user needs Or replace a CM that seems to be less effective.

  Specifically, for example, at the start of reproduction of the program content, the program content ID or the CM ID list in the program content, the user's attribute information, information reflecting preferences, access history to the CM information, Is sent to the advertisement providing server 640, or the advertisement providing server 640 obtains the feedback information from the user information management server 650 that stores the information, and the content reproducing apparatus 300 displays the URL list of the CM group selected based on the information. It is conceivable to play back the CM received from the providing server 640 and obtained by accessing the URLs at the playback timing of the CM section.

  In the above description, the case where the reproduction restriction is released based on the information on the number of times of normal reproduction has been described. However, when the reproduction restriction is released based on the information on the time limit, the content reproduction apparatus 300 performs substantially the same reproduction operation. I do. The playback operations shown in the flowcharts of FIGS. 13, 14, 15, and 16 respectively show the playback operations of the content playback device 300 when the release of the playback restriction is performed based on the information on the time limit. , FIG. 8, FIG. 10, and FIG. However, the processing of ST11 of FIG. 13, ST33 of FIG. 14, and ST53 of FIG. 15 may be performed only when the reproduction restriction by the time limit and the number of times is used together.

  In the flowchart of FIG. 13, the process of step ST7 in the flowchart of FIG. 6 is changed to the process of step ST7A, and the other steps are the same as those in the flowchart of FIG. In this step ST7A, the content reproduction device 300 determines whether or not the current time is before the time limit of the reproduction restriction. When judging that it is before the time limit of the reproduction restriction, the content reproduction device 300 moves to the processing of step ST8. On the other hand, when determining that it is not before the time limit of the reproduction restriction, the content reproduction device 300 proceeds to the process of step ST9.

  In the flowchart of FIG. 14, the process of step ST25 in the flowchart of FIG. 8 is changed to the process of step ST25A, and the other steps are the same as those in the flowchart of FIG. In this step ST25A, the content reproduction device 300 determines whether or not the current time is before the time limit of the reproduction restriction. When judging that it is before the time limit of the playback restriction, the content playback apparatus 300 moves to the process of step ST26. On the other hand, when determining that the current time is not before the time limit of the reproduction restriction, the content reproduction apparatus 300 proceeds to the process of step ST35.

  In the flowcharts of FIGS. 15 and 16, the process of step ST45 in the flowcharts of FIGS. 10 and 12 is changed to the process of step ST45A, respectively. Is the same. In this step ST45A, the content reproduction device 300 determines whether or not the current time is before the time limit of the reproduction restriction. When judging that it is before the reproduction time limit, the content reproduction device 300 moves to the process of step ST46. On the other hand, when determining that the current time is not before the time limit of the reproduction restriction, the content reproduction device 300 proceeds to the process of step ST55.

  By the way, in free digital broadcasting / distribution based on advertising revenue, if time-shifted viewing becomes common with the spread of digital recording / playback equipment, real-time audience rating data, which is the basis of the advertising business model, is meaningless. No longer. When a CM (CM section) is normally reproduced (reproduced at a normal speed) before a predetermined period (for example, a period during which CM skip / fast-forward is restricted), an advertisement audience rating measurement server 620 that measures audience rating is accessed. Thus, it is conceivable to add the same rating as in the case of real-time viewing.

  Here, the advertisement audience rating measurement server 620 is a server for measuring data serving as a basis for calculating an advertisement fee, recognizes CMs stored in the storage unit, and plays back the CMs in a preset viewing / listening mode. If the rate measurement condition is satisfied, it is added as the advertisement audience rating. In this case, it is possible to collect audience rating (CM audience rating) data based on actual numbers actually viewed, instead of estimated audience ratings based on samples.

  For a user (viewer), if the user views and listens to the program content stored in the storage unit during the CM skip / fast-forward restriction period, the point server 630 receives the CM as a privilege. It is conceivable to access and give points to the point card linked to the user.

  Here, the point server 630 is a server for returning the price (point) for the user viewing the CM to the viewer, and recognizes the CM stored in the storage unit, and the reproduction of the CM is set in advance. If the conditions are satisfied, points are given to the point card linked to the user. The user can use the points to pay for pay-TV viewing, pay for program playback (recorded or downloaded programs) with billing, pay for VOD (video-on-demand) services via the Internet, and the like. Things become possible.

  Even when the CM skip / fast-forward restriction period has not elapsed, if the CM is normally reproduced a predetermined number of times, for example, only once, the restriction on the CM skip / fast-forward is made at the second and subsequent times. May not be performed.

  When a predetermined time period (for example, a time period during which CM skip / fast-forward is restricted) elapses, the CM stored in the storage unit is considered to have a reduced advertising value, and the advertisement on the cloud is It is conceivable that the CM is replaced with a CM obtained from the (CM) providing server 640. As the replacement CM, a CM based on the past viewing tendency of the user (viewer) of the program content and a regional CM based on information such as the program viewing area are selected.

  Here, the advertisement (CM) providing server 640 is a server for providing a CM to a user (viewer), and if a predetermined condition is satisfied, an old CM or commercial Provide commercials with high commercial value in place of commercials with low value. In this case, regarding the CM viewing supplied from the advertisement (CM) providing server 640, it is conceivable to return the price (point) for the user viewing the CM.

  The flowchart in FIG. 17 illustrates an example of the playback operation of the content playback device 300. The content reproduction device 300 starts the process in step ST61. Then, in step ST62, in the normal reproduction state of the program content, after detecting the head of the CM section X, the process proceeds to step ST63.

  In this step ST63, the content reproduction device 300 determines whether or not the current time is before the time limit of the reproduction restriction. If it is before the time limit of the reproduction restriction, in step ST64, the content reproduction device 300 determines whether the number of times of reproduction of the CM section X is less than a predetermined required number of times. When judging that the number is less than the required number, in step ST65, the content reproduction device 300 turns on the skip / fast-forward prohibition mode.

  After the process of step ST65, the content reproduction device 300 proceeds to a process of step ST66. If it is determined in step ST63 that it is after the time limit of the reproduction restriction, or if it is determined in step ST64 that the number of times of reproduction of the CM section X is equal to or more than the required number, the content reproduction device 300 immediately proceeds to the process of step ST66. .

  In step ST66, the content reproduction device 300 determines whether or not the advertisement replacement condition is satisfied. For example, it is determined that the advertisement replacement condition is satisfied when the current time is after the time limit of the reproduction restriction, or when the reproduction number of the CM section X is equal to or more than the required number even if the current time is within the time limit of the reproduction restriction. When determining that the advertisement replacement condition is satisfied, in step ST67, the content reproduction device 300 acquires a replacement CM from the advertisement (CM) providing server 640 and performs normal reproduction.

  After the process of step ST67, the content reproducing device 300 proceeds to a process of step ST68. When determining that the advertisement replacement condition is not satisfied in step ST66, the content reproduction device 300 immediately proceeds to the process of step ST68.

  In step ST68, the content reproduction device 300 determines whether the end of the CM section X or the end of the replacement CM has been detected. When judging that it has been detected, in step ST69, the content reproduction device 300 increments the number of times of reproduction of this CM section, that is, increments the number by "+1". Next, in step ST70, the content reproduction device 300 turns off the skip / fast-forward prohibition mode.

  Next, in step ST71, the content reproduction device 300 determines whether or not the CM section X is a target of audience rating measurement. When judging that the content is to be subject to audience rating measurement, the content reproduction device 300 accesses the advertisement audience rating measurement server 620 and registers the audience rating in step ST72.

  After the process of step ST72, the content reproducing device 300 proceeds to a process of step ST73. When determining in step ST71 that the content is not a target of audience rating measurement, the content reproduction device 300 immediately proceeds to the process of step ST73.

  In this step ST73, the content reproduction device 300 determines whether or not the CM section X is a point target. When judging that the content is to be pointed, the content reproduction device 300 accesses the point server 630 in step ST74 and performs compensation (point) for viewing in the CM section X.

  After the process of step ST74, the content reproduction device 300 ends the process in step ST75. When determining in step ST73 that the content is not a point target, the content reproduction device 300 immediately ends the processing in step ST75.

  Note that the content reproduction device 300 analyzes the viewing history and recording history of the user (viewer) and presents recommended program contents in the same manner as presenting a list of program contents stored (recorded) in the storage unit. It is also conceivable to select and present from program contents provided by VOD (video on demand). In this case, as the fee required for viewing the VOD program, for example, it is possible to use the points given in the CM viewing as described above. Of course, normal credit card charging and charging by electronic money are also possible.

  Free broadcasts are broadcasts that can be viewed free of charge, but when providing high value-added content, it is conceivable to charge for recording the content. For example, as described above, payment using points given in CM viewing, billing by credit card, and billing by electronic money are also conceivable.

  In addition, a business model in which charging is performed when a recorded program is reproduced, instead of charging when recording, is also conceivable. A method of charging for each reproduction, a method of charging for the subsequent reproduction when the number of times of reproduction exceeds a certain number of times, and a method of charging for reproduction after a certain period of time instead of the number of times of reproduction are possible. When the user (viewer) selects the CM viewing, a business model that enables continuous free reproduction is also conceivable.

  As described above, in the transmission / reception system 10 shown in FIG. 1, when the reproduction restriction (skip / fast-forward prohibition) of the CM section is not released, the content reproduction apparatus 300 restricts the CM section to normal reproduction. . In this case, even if a skip / fast-forward request is made by a user operation during normal reproduction of this CM section, the request is not accepted. Therefore, when reproducing the stored program content, it is possible to appropriately reproduce the CM section included therein.

  In the transmission / reception system 10 shown in FIG. 1, the broadcast transmission system 100 or the program providing server (distribution server) 200 transmits information indicating a CM section included in the program content or information for acquiring the information. Therefore, on the receiving side, the CM section in the program content can be accurately recognized, and the reproduction operation can be correctly restricted for the CM section.
