Abstract

PROBLEM TO BE SOLVED: To provide a portable terminal which allows efficient viewing of program data while avoiding reduction in the number of times of copy restriction.SOLUTION: A server is configured to store N-th consecutive program data (N is an integer not smaller than 1) representing distributed consecutive programs and to be capable of moving program data to the portable terminal. The portable terminal comprises: reproduction means capable of reproducing the N-th consecutive program data moved from the server; and control means for controlling moving processing of the program data between the server and the terminal device. The control means determines whether reproduction of the N-th consecutive program data by the reproduction means has been completed or not by the reproduction means. When determining that the reproduction has been completed, the control means accesses to the server to determine whether there is (N+1)-th consecutive program data. When determining that there is (N+1)-th consecutive program data, the control means executes moving processing from the portable terminal to the server relating to the N-th consecutive program data and executes moving processing of the (N+1)-th consecutive program data from the server to the portable terminal.

Description

  The present invention relates to a portable terminal and a broadcast program storage system, and more particularly to a portable terminal and a broadcast program storage system that reproduce program data having copy restrictions.

  In recent years, a recording / reproducing apparatus (hereinafter also referred to as a server) that receives program data representing a television broadcast program transmitted from a broadcast station and stores the program data in a storage unit has become widespread (Patent Documents 1 and 2).

  In response to a program data output instruction from the user, the program data stored in the storage unit is decoded, moving image data of the program data is displayed on a display device, and audio data of the program data is output to a speaker. Thus, the user can view the program data stored in the storage unit of the server.

  In addition, with the spread of network technology, a method in which other external devices and servers operate in cooperation has also become popular. For example, it is possible to connect a server and a mobile terminal, copy program data stored in the storage unit of the server to the mobile terminal, and view the program data according to the user's preference on the mobile terminal ( Patent Document 3).

  It is also possible to operate a mobile device such as a portable terminal to instruct a server that is fixedly installed to record program data (Patent Document 4).

  On the other hand, various techniques for appropriately managing contents and preventing illegal downloads have been proposed (Patent Document 5).

JP 2001-256692 A JP 2006-60630 A JP 2006-279698 A JP 2008-288725 A Special table 2009-536482 gazette

  Although the technique described in Patent Document 5 is digital music content, copy restrictions are often provided in recent years for program data such as broadcast programs.

As copy restrictions, “copy once” and “dubbing 10” are mainly cited.
“Copy Once” refers to a mechanism for copying content for one generation (Copy One Generation).

  “Dubbing 10” is a mechanism that allows copying 9 times and moving only once.

  “Copy once” and “dubbing 10” are the same in that they control “copy only for one generation”, but the origin of “generation” is different.

  Since “copy once” starts from broadcasting, it was the first generation copy at the time of recording on the recording / playback apparatus. Therefore, in the case of “copy once”, copying from a recording / reproducing apparatus (for example, HDD recorder or the like) to another external device is impossible and only moving is possible. Etc.), and when recording on a recording / playback device (such as an HDD recorder), it is not the first generation, and copying from that to another medium (DVD, memory card, etc.) is the first generation. There is.

  In the dubbing 10, the number of first-generation copies is 9 times, the move is 1 time, and the second-generation copy is prohibited.

  In order to access the server and view the program data on the mobile terminal without reducing the copy limit frequency when there is such a copy restriction, conventionally, the program data stored in the server is manually moved to the mobile terminal ( After moving and viewing, it is necessary to move (move) to the server again, which is a very complicated operation.

  The present invention has been made to solve the above problems, and provides a portable terminal and a broadcast program storage system capable of efficiently viewing program data without reducing the number of times of copying. The purpose is to do.

  A mobile terminal according to an aspect of the present invention is a mobile terminal provided so as to be able to communicate with a server for storing distributed program data having copy restrictions, and the server is an Nth representing a distributed continuous program. Continuous program data (N is an integer equal to or greater than 1) is stored, and the program data is configured to be movable with respect to the mobile terminal, and the mobile terminal is capable of reproducing the Nth continuous program data moved from the server; And control means for controlling the program data transfer process with the server. The control means determines whether or not the reproduction of the Nth continuous program data has been completed by the reproduction means. If the reproduction means determines that the reproduction has been completed, the control means accesses the server and has the (N + 1) th continuous program data. If it is determined that there is (N + 1) th continuous program data, the mobile terminal performs a movement process from the portable terminal to the server for the Nth continuous program data, and the (N + 1) th continuous program from the server to the portable terminal. Execute data movement processing.

  Preferably, the control means accesses the server at a predetermined time and determines whether or not the (N + 1) th continuous program data is included.

  Preferably, the control means measures the load ratio of the portable terminal, and when the load ratio is less than a predetermined value, accesses the server to determine whether or not the (N + 1) th continuous program data is included.

  Preferably, the control means determines that the reproduction has been completed when a predetermined ratio or more of the total reproduction time is reproduced for the reproduction of the Nth continuous program data.

  Preferably, the control means determines that the reproduction of the Nth continuous program data is completed according to an operation instruction from the user.

  Preferably, the program data has a program identifier including information on the number of episodes of the continuous program, and the control means accesses the server and talks of the number next to the number of stories included in the program identifier of the Nth consecutive program data. It is determined whether or not information indicating the number or the last story has (N + 1) th continuous program data included in the program identifier.

  A broadcast program storage system according to an aspect of the present invention includes a server for storing distributed program data having copy restrictions and a mobile terminal, and the server includes Nth continuous program data representing the distributed continuous program. (N is an integer greater than or equal to 1) and program data can be moved with respect to the mobile terminal. The mobile terminal can play back the Nth continuous program data moved from the server, a server, Control means for controlling the movement processing of the program data between the control means, the control means judges whether or not the reproduction of the Nth continuous program data is completed by the reproduction means, and judges that the reproduction is completed In this case, the server is accessed to determine whether or not the (N + 1) th continuous program data is present. If it is determined that the (N + 1) th continuous program data is present, the Nth continuous program data is determined. For running the moving process to the server from the portable terminal, the relative mobile terminal from the server (N + 1) executes a moving process of continuous program data.

  It is possible to view program data efficiently without reducing the copy limit number.

The input unit 29 receives various operation instructions from the user.
For example, it is assumed that the user can view the program data stored in the storage area 22 of the storage unit 21 by a predetermined operation instruction according to the operation of the input unit 29. For example, the reproduction of the program data is started by executing a selection operation for reproducing the program data of the title A and the Nth episode stored in the storage area 22.

FIG. 5 is a diagram for explaining the movement of program data according to the present embodiment.
Referring to FIG. 5 (A), a case where title A and Nth episode program data are stored in server (HDD recorder) 1 is shown. In addition, program data of the same title A and (N + 1) th episode is stored. Here, it is assumed that dubbing 10 is set as the copy restriction.

  With reference to FIG. 5 (B), the case where the program data of the title A and the Nth story stored in the server 1 is moved to the mobile terminal (mobile phone) 2 is shown.

As a result, the copy number of the program data stored in the server 1 is nine.
The portable terminal 2 stores title A and Nth episode program data.

  In this state, it is assumed that the user can view program data stored in accordance with a predetermined operation instruction according to the operation of the input unit 29 in the mobile terminal 2. For example, the reproduction of the program data is started by executing a selection operation for reproducing the program data of the title A and the Nth episode.

  Referring to FIG. 5C, after viewing of the title A and the Nth episode program data is finished in portable terminal (mobile phone) 2, title A is transferred from portable terminal (mobile phone) 2 to server 1. The program data of the Nth episode is moved.

  As a result, as the program data stored in the server 1, the program data of the title A and the Nth episode copy number is stored together with the program data of the title A and the Nth episode copy count of 9. Therefore, by moving instead of deleting the program data, the program data copy count is restored, and the portable terminal 2 can view the program data without reducing the copy limit count.

  Referring to FIG. 5D, the case where the program data of title A and (N + 1) th story stored in server 1 is moved to mobile terminal (mobile phone) 2 is shown.

As a result, the copy number of the program data stored in the server 1 is nine.
The portable terminal 2 stores the program data of the title A and the (N + 1) th episode.

  In this state, it is assumed that the user can view program data stored in accordance with a predetermined operation instruction according to the operation of the input unit 29 in the mobile terminal 2. For example, the reproduction of the program data is started by executing a selection operation for reproducing the program data of the title A and the (N + 1) th episode.

  The movement of the program data can be executed in accordance with the user's operation instruction (manual) via the input unit, but in the present embodiment, the case where it is automatically executed without depending on the user's operation instruction will be described. To do.

  Specifically, a method of storing the program data of the title A and the (N + 1) th episode in the portable terminal 2 without the user's operation when viewing the program data of the title A and the Nth episode will be described. However, regarding the program data of the title A and the first episode, the storage in the storage area 22 of the portable terminal 2 is executed according to a user operation instruction. The program data may be moved from the server 1 side to the portable terminal 2 in accordance with a user operation instruction, or the program data may be moved by accessing the server 1 from the portable terminal 2 side.

  FIG. 6 is a flowchart illustrating program data playback processing in portable terminal 2 according to the present embodiment. The processing is mainly processing executed by the CPU 24. The reproduction process can be executed when program data is stored in the storage area 22 of the storage unit 21 of the mobile terminal 2.

  Referring to FIG. 6, CPU 24 determines whether reproduction of program data has been started (step S2). Specifically, the CPU 24 determines whether or not an instruction to start reproduction is given to the program data stored in the storage area 22 via the input unit 29.

  In step S2, when the reproduction of the program data is started, the CPU 24 next determines whether or not the program data has been interrupted (step S4). Specifically, it is determined whether or not the interruption flag is on in a movement flag status described later.

  If it is determined in step S4 that the program data has been interrupted (YES in step S4), the CPU 24 reproduces the interrupted program data (step S16).

Then, the process proceeds to step S8.
When CPU 24 determines that the program data has not been interrupted (NO in step S4), it reproduces the program data (step S6). That is, the program data is reproduced from the beginning.

  Next, the CPU 24 determines whether or not the reproduction is interrupted or whether or not the reproduction is finished (step S8). Specifically, the CPU 24 determines whether or not an instruction to interrupt the reproduction of the program data is given via the input unit 29. Alternatively, it is determined whether or not the program data has been reproduced to the end.

  If the CPU 24 determines in step S8 that the reproduction is interrupted, the process proceeds to step S10. On the other hand, if it is determined that the reproduction is not interrupted, the process returns to step S6 and the reproduction is continued until the program data is completed.

  If the CPU 24 determines in step S8 that the reproduction of the program data has ended, the process proceeds to step S10.

  In step S10, the CPU 24 determines whether or not the reproduction completion condition has been reached.

  If it is determined in step S10 that the reproduction completion condition has been reached, the CPU 24 turns on the reproduction completion flag (step S12). In this example, the case where the condition for completion of reproduction is satisfied includes not only the case where program data is reproduced to the end but also the case where reproduction of 90% or more of the total reproduction time is completed, for example. Shall. Alternatively, the case where the reproduction is completed according to a predetermined operation instruction by the user even when the reproduction time is less than 90% is included. For example, there is a case where a selection screen for determining whether or not reproduction is considered to be complete is displayed, and an operation instruction is given on the selection screen to regard that reproduction is complete or the like.

Then, the process ends (END).
On the other hand, if the CPU 24 determines in step S10 that the reproduction completion condition has not been reached (NO in step S10), it turns on the interruption flag (step S14). When the interruption flag is turned on, information necessary for reproducing the program data from the interruption point is stored again. For example, information such as the interrupted time can be included.

Then, the process ends (END).
Next, a moving process for moving program data (N episodes) stored in the portable terminal 2 that has been reproduced to the server 1 and moving other related program data (N + 1 episodes) from the server 1 will be described. .

  FIG. 7 is a flowchart illustrating program data movement processing in portable terminal 2 according to the present embodiment. The processing is mainly processing executed by the CPU 24.

  Referring to FIG. 7, CPU 24 determines whether it is a designated time (step S20). In the present embodiment, a case where program data movement processing is executed at a designated time designated in advance by the user will be described as an example.

  Next, when it is determined that it is the designated time (YES in step S20), the CPU 24 next determines whether or not the server 1 is already connected (step S22). That is, it is determined whether the portable terminal 2 is in a state where it can communicate with the server 1.

  In step S22, if the CPU 24 determines that it is already connected to the server 1 (YES in step S22), it checks the movement flag status (step S24).

FIG. 8 is a diagram for explaining the movement flag status according to the present embodiment.
With reference to FIG. 8, the movement flag status is stored in the storage area 22 of the storage unit 21. Here, a case where a movement flag and a reproduction completion flag are provided is shown. When the movement flag is “0”, it indicates that there is no movement of program data. It is an initial state. When the movement flag is “1”, it indicates that the reproduced program data has been moved to the server 1.

  When the reproduction completion flag is “0”, it indicates that the reproduction of the stored program data has not been completed. When the reproduction completion flag is “1”, it indicates that the reproduction of the stored program data has been completed.

  As states of possible values, the initial state is a movement flag, and the reproduction completion flag is “0” or “0”. When the reproduction of the program data is completed, the movement flag and the reproduction completion flag are “0” and “1”. When the movement of the reproduced program data is completed, the movement flag and the reproduction completion flag are “1” and “1”.

  Referring to FIG. 7 again, next, CPU 24 determines whether or not a movement process is necessary based on the movement flag status (step S26). Specifically, it is determined whether or not the reproduction completion flag is “1”.

  If the CPU 24 determines that movement processing is necessary (YES in step S26), it next determines whether there is movement target program data (step S28). Specifically, as an example, the next program data is accessed based on the program identifier (title A, Nth episode) of the program data according to the list related to the program information stored in the management table 13 by accessing the server 1. It is determined whether (title A, (N + 1) story) is stored in the storage area 12 of the server 1. For example, for the same title, it is possible to determine whether there is program data of the next number with respect to the number of stories. In the case of “last episode” or “last episode” program data regarding the number of episodes, the number of episodes may not be specified by the following number as the program identifier of the program data. If the program identifier is not specified in the next number, for example, the (N + 1) th episode, it is determined whether or not a character such as “final story” or “final episode” is included, and the character is included. If it is, it can be determined that there is program data to be moved. “Final story” or “final episode” is an example, and is an example of a character that identifies the end of continuous program data. The end of the continuous program data may be specified by another character or the like. Any case may be used as long as it can be specified. That is, in this example, the program data of “last episode” or “last episode” can be similarly processed as the (N + 1) -th episode program.

  In step S28, when CPU 24 determines that there is program data to be moved (YES in step S28), CPU 24 determines whether or not there is a program data storage capacity (step S30). Specifically, it is determined whether or not there is a storage capacity capable of storing the next program data in the storage area 22. At this time, in this example, since the program data is moved to the server 1 and the next program data is moved from the server 1, the next program data is taken into consideration in consideration of the capacity of the program data to be moved to the server 1. The storage capacity may be determined as to whether or not it can be moved from the server 1.

  In step S30, when CPU 24 determines that there is a program data storage capacity (YES in step S30), CPU 24 determines whether there is program data that has been played back (step S32). Specifically, the movement flag status is confirmed to determine whether or not the movement flag is “0”. This is because when the movement flag is “1”, the program data that has already been reproduced has been moved to the server 1.

  If the CPU 24 determines in step S32 that there is program data that has been played back (YES in step S32), it moves the program data to the server 1 (step S34). For example, the CPU 24 moves the program data of the title A and the Nth episode stored in the storage area 22 to the server 1 via the communication unit 28.

  Next, the CPU 24 updates the movement flag status (step 36). Specifically, the CPU 24 sets the movement flag of the movement flag status to “1”.

  Then, the CPU 24 moves program data from the server 1 (step S38). Specifically, as an example, the program data next to the title A and the Nth episode (title A, the (N + 1) th episode) is accessed according to the list related to the program information stored in the management table 13 by accessing the server 1. Is moved to the portable terminal 2. In response to the instruction, the server 1 transmits the program data of the title A and the (N + 1) th episode to the mobile terminal 2 via the communication unit 18. Then, the portable terminal 2 receives the program data of the title A and the (N + 1) th episode transmitted from the server 1 via the communication unit 28 and stores them in the storage area 22. Thereby, the program data of the title A and the (N + 1) th episode can be reproduced.

  Next, the CPU 24 resets the movement flag status (step S40). Specifically, the initial state is restored. That is, both the movement flag and the reproduction completion flag are set to “0”.

Then, the process ends (END).
If the CPU 24 determines in step S32 that there is no program data that has been played back (NO in step S32), the process proceeds to step S38. Specifically, the movement flag status is confirmed, and if the movement flag is “1”, since the program data that has been reproduced has already been moved, steps S34 and S36 are skipped.

Subsequent processing is the same as described above.
In step S28, when CPU 24 determines that there is no program data to be moved (NO in step S28), CPU 24 determines whether there is program data that has been played back (step S42). Specifically, the movement flag status is confirmed to determine whether or not the movement flag is “0”. This is because when the movement flag is “1”, the program data that has already been reproduced has been moved to the server 1. A case where it is determined that there is no program data to be moved includes, for example, a case where program data of the next number of stories is not stored in the storage area 12 of the server 1.

  CPU 24 also proceeds to step S42 when determining that there is no program data storage capacity (NO in step S30).

  If it is determined in step S42 that there is program data that has been played back (YES in step S42), the CPU 24 determines whether to move the program data that has been played back (step S44). Specifically, as an example, a selection screen as to whether to move the program data that has been reproduced is presented to the user, and a determination is made according to the user's selection instruction.

  In step S44, when CPU 24 determines to move the program data that has been reproduced (YES in step S44), it moves the program data to server 1 (step S46). Specifically, for example, the CPU 24 moves the program data of the title A and the Nth episode stored in the storage area 22 to the server 1 via the communication unit 28.

  Then, the CPU 24 updates the movement flag status (step S48). Specifically, the CPU 24 sets the movement flag of the movement flag status to “1”.

  Then, the process ends (END). Even when program data of the next number of stories is not stored in the storage area 12 of the server 1, the program data that has been reproduced can be moved to the server 1 to secure the storage area. In addition, by moving the program data that has been played back in advance to the server 1, it is possible to quickly execute the process related to the movement of the program data of the next number of stories.

  On the other hand, if the CPU 24 determines in step S42 that there is no reproduction completed program data (NO in step S42), or if it is determined in step S44 that the program data is not to be moved (NO in step S44). The process is terminated (end). Specifically, the movement flag status is confirmed, and if the movement flag is “1”, the program is already completed and the process is terminated.

  For example, a case will be described in which the portable terminal 2 according to the present embodiment reproduces the program data of the title A and the first episode in accordance with a user operation instruction and the reproduction is completed.

  When the designated time comes, the flowchart of FIG. 7 is executed, and when it is determined that the reproduction of the program data of the title A and the first episode is completed (that is, the reproduction completion flag of the movement flag status is “ 1 ”), the program data of the title A and the first episode is moved to the server 1 via the communication unit 28. Then, the portable terminal 2 receives the title A and the program data of the second episode from the server 1 via the communication unit 28 and stores them in the storage area 22. Then, the portable terminal 2 again performs the same processing as described above with reference to FIG. 7 when the reproduction of the program data of the title A and the second episode is completed according to the user's operation instruction when the designated time comes. Execute. That is, the program data of the title A and the second episode is moved to the server 1 and the program data of the third episode is moved from the server 1. The same applies to the subsequent processing.

  By this processing, for example, when the reproduction of the program data of the title A and the first episode is completed, the user automatically acquires the program data of the title A and the second episode that are continuous programs from the server 1. It can be played back on the mobile terminal 2. At this time, the program data moved from the server 1 to the portable terminal 2 can be moved back to the server 1 and returned, so that the processing can be executed without reducing the copy limit count. And since the said process is automatically performed when the designated time comes, program data can be efficiently reproduced (viewed) without forcing the user to perform complicated operations.

  The designated time can be set by the user, and the program data moving process can be executed more efficiently by setting the period when the user does not operate the portable terminal 2.

  Further, for example, for program data broadcasted weekly as a continuous program, after the user completes the reproduction of the program data of the first episode, the program data of the next number of episodes after that is not stored in the server 1 However, after being stored in the server 1, it is possible to move the program data of the next number of stories to the portable terminal 2 without user operation.

  In this example, the case of executing the movement process flow of FIG. 7 at the specified time is described. However, the user does not specify, but for example, the CPU 24 measures the load ratio of the mobile terminal 2. Thus, when the load ratio is less than the predetermined value, the movement process flow of FIG. 7 may be executed. In the case of the process, the process can be executed at a time when no load is applied, and an efficient movement process is possible. Moreover, you may make it perform the said process for every predetermined period.

  In addition to the designated time, a designated date / time, a designated day of the week, etc. may be set to execute the movement process flow of FIG.

  In this example, the case of dubbing 10 has been described as copy restriction. However, the present invention can be similarly applied to the case of copy once.

  In this example, the program data distributed from the broadcasting station has been described as an example. However, the program data is not limited to the program data distributed from the broadcasting station, and may be, for example, program data downloaded from the outside via a network. There may be.

  The embodiment disclosed this time is an exemplification, and the present invention is not limited to the above contents. The scope of the present invention is defined by the terms of the claims, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
