Description

  The present invention relates to a playback device, a playback method, and a playback program for playing back program recording data.

  2. Description of the Related Art Conventionally, there is a technique for skipping a series of commercial messages (hereinafter, CM) in a television program when the recorded television program is played back and viewed. For example, there is a technique for skipping a CM by skipping to a chapter attached to recorded data of a television program. The chapter is a delimiter (or a mark) indicating the boundary between the main program and the CM, and is given by, for example, a recording device that records the program. Also, the audio format of programs and CMs are often different (for example, stereo audio and monaural audio), and chapters are assigned to, for example, change points of the audio format. Hereinafter, sections that are divided by chapters and that include only CMs are referred to as CM chapters.

  However, the chapter given to the recording data of the television program is not necessarily given to the switching point between the program and CM, and may not be given to the switching point between the program and CM. For this reason, when the user skips the CM by chapter transmission, a part of the program is skipped excessively. In this case, the user searches for a desired viewing point by rewinding or fast-forwarding while watching the screen. This operation is inconvenient for the user, and there is a problem that eyes are tired because the operation is performed while looking at the screen.

  An object of one aspect of the present invention is to provide a playback device, a playback method, and a playback program that improve the efficiency of a CM skip operation in program recording data.

An average calculating unit for calculating an average time of a section included in a predetermined range in which a time length of a section divided by a plurality of break points given to the program recording data is determined as a CM section;
A calculation unit for calculating a threshold time according to the average time;
When a skip command is received from the user during playback of the program recording data, if the time length to the next breakpoint is longer than the threshold time, the playback position is skipped by the average time and the time until the next breakpoint is reached. When the time length is shorter than the threshold time, a control unit that causes the playback position to be skipped to the next breakpoint;
Is a playback device.

Another aspect of the present invention is a playback method executed by the playback apparatus described above. In addition, another aspect of the present invention can include a playback program that causes a computer to function as a playback device, and a computer-readable recording medium that records the playback program. The computer-readable recording medium refers to a recording medium in which information such as data and programs is accumulated by electrical, magnetic, optical, mechanical, or chemical action and can be read from the computer or the like.

  FIG. 1 is a diagram illustrating an example of a hardware configuration of an information processing system. The information processing system 100 is a system for recording a television program and reproducing the program recording data. The playback device according to the first embodiment is a device included in the information processing system 100. The playback device is, for example, a Blu-ray recorder, HDD recorder, personal computer (PC), mobile phone terminal, smartphone, tablet PC, PDA (Personal Digital Assistant), TV receiver having a recording function, car navigation device, game device, etc. This is a device having a function of reproducing program recording data.

The information processing system 100 includes a CPU (Central Processing Unit) 101, a graphic processing unit 102, a memory / video controller 103, a memory 104, a TV tuner unit 105, a hard disk 106, an I / O controller 107, a network interface 108, and an input receiving unit 109. , A display unit 110 is provided.

  The input receiving unit 109 receives an operation input from the user. For example, the input reception unit 109 is a pointing device such as a touch pad, a mouse, or a touch panel, a keyboard, operation buttons, a circuit that receives a signal from a remote controller, and the like. The input reception unit 109 is connected to the I / O controller 107, and the operation signal input to the input reception unit 109 is output to the I / O controller 107.

The TV tuner unit 105 is connected to a TV antenna, and decodes a signal corresponding to a frequency of a predetermined channel from a TV broadcast radio signal received by the TV antenna. The TV tuner unit 105 is connected to the I / O controller 107, and the signal decoded by the TV tuner unit 105 is output to the I / O controller 107.

  The network interface 108 is an interface for inputting / outputting information to / from the network. The network interface 108 connects to a wired network and a wireless network. The network interface 108 is, for example, a NIC (Network Interface Card), a wireless LAN (Local Area Network) card, or the like. The network interface 108 is connected to the I / O controller 107, and data received by the network interface 108 is output to the I / O controller 107.

The hard disk 106 stores various programs and data used by the CPU 101 when executing each program. The hard disk 106 stores program recording data and a skip control program. The skip control program is a program for controlling a skip operation during reproduction of program recording data. The skip control program is an example of a “reproduction program”. The information processing system 100 may include, for example, a nonvolatile memory such as an EPROM (Erasable Programmable ROM) or a flash memory instead of the hard disk 106. The hard disk 106 is connected to the I / O controller 107, and data read from the hard disk 106 is output to the I / O controller 107.

  The I / O controller 107 includes a relatively narrow bandwidth bus, input / output ports, and the like, and connects the TV tuner unit 105, the hard disk 106, the network interface 108, and the input reception unit 109, and bridges data among them. . The I / O controller 107 is connected to the memory / video controller 103 via a dedicated bus, and data input from the TV tuner unit 105, the hard disk 106, the network interface 108, and the input receiving unit 109 is output to the memory / video controller 103. Is done.

  The memory 104 provides the CPU 101 with a storage area and a work area for loading a program stored in the hard disk 106, and is used as a buffer. The memory 104 is a semiconductor memory such as a RAM (Random Access Memory), for example.

  The CPU 101 executes various processes by loading the OS and various application programs held in the hard disk 106 into the memory 104 and executing them. There may be one CPU 101 or a plurality of CPUs. The CPU 101 is connected to the memory / video controller 103 and outputs the processing result to the memory / video controller 103.

  The memory / video controller 103 includes a bus and an input / output port having a relatively wide bandwidth, and is connected to the CPU 101, the graphic processing unit 102, and the memory 104, and performs data bridging among them. The memory / video controller 103 is connected to the I / O controller 107 by a dedicated bus.

  The graphic processing unit 102 performs image processing of an image displayed on the display unit 101. The graphic processing unit 102 is, for example, a GPU (Graphics Processing Unit). The graphic processing unit 102 is connected to the display unit 101 and outputs a processing result.

The display unit 101 is a device that displays the result of processing input from the graphic processing unit 102. The display unit 101 is, for example, a liquid crystal display, an organic EL (Electro-Luminescence
) Display and plasma display.

In addition to the information processing system 100 shown in FIG. 1, the information processing system 100 includes, for example, a portable recording medium driving device and an audio output device. The portable recording medium driving device is connected to the I / O controller 107, reads out programs and various data recorded on the portable recording medium, and outputs them to the I / O controller 107. Data read from the portable recording medium is processed by the CPU 101. Portable recording media include, for example, an SD card, a miniSD card, a microSD card, a USB (Universal Serial Bus) flash memory, a CD (Compact Disc), a DVD (Digital
Versatile Disk), Blu-ray Disc, or a recording medium such as a flash memory card.

  The playback apparatus includes at least a CPU 101, a memory 104, a hard disk 106, an input receiving unit 109, a memory / video controller 103, and an I / O controller 107 among the hardware components shown in FIG. In addition to these, the playback device includes a display unit 110, a graphic processing unit 102, a television tuner unit 105, and a network interface 108 in accordance with the form. In addition, the information processing system 100 and the playback device can add or replace components as appropriate, without being limited to the hardware illustrated in FIG.

  For example, in the playback apparatus, the CPU 101 loads a skip control program held in the hard disk 106 to the memory 104 and executes it. Through the execution of the skip control program, for example, the playback device plays back program recording data stored in the hard disk 106, accepts a skip operation input from the user, and skips the playback position. The playback device may read and play back the program recording data stored in the portable recording medium according to the form, or may play back the program recording data received from the network interface 108 through the network.

FIG. 2 is an example of a functional block diagram of the playback device 1. For example, when the CPU 101 executes a skip control program stored in the hard disk 106, the playback device 1 operates as a chapter interval acquisition unit 11, a CM average time calculation unit 12, a threshold setting unit 13, and a skip control unit 14. However, these functional blocks are not limited to being realized by executing a skip control program, and may be realized by hardware such as an electric circuit or / and an electronic circuit such as an FPGA (Field-Programmable Gate Array). .

  The chapter interval acquisition unit 11 acquires and outputs the time length of each section divided by chapters given to the program recording data.

  The CM average time calculation unit 12 receives the time length of each section output from the chapter interval acquisition unit 11. The CM average time calculation unit 12 extracts a section that can be regarded as a CM chapter from the program recording data using the CM determination range. The CM determination range is a time length range in which a section can be regarded as a CM chapter, and is set, for example, by adding an error range to a general CM interval. For example, the CM determination range is a general CM time length of 2 minutes ± error range of 1 minute. The CM average time calculation unit 12 calculates the average of the extracted time lengths of the sections and outputs the average as the CM average time. When there is no time length section corresponding to the CM determination range, the CM average time calculation unit 12 outputs a general CM time length as the CM average time. The CM average time is used as one of skip lengths when a skip operation command is input. The general CM time length and CM determination range may be set according to the type and length of the program. For example, a typical CM time length is 2 minutes for a drama, 3 minutes for a variety, and the like. For example, the CM determination range is within 1 minute for a 5-minute program, within 3 minutes for a 30-minute program, and within 6 minutes for a 60-minute program.

  The CM average time output from the CM average time calculation unit 12 is input to the threshold setting unit 13. The threshold setting unit 13 sets a skip threshold based on the CM average time. The skip threshold value is a threshold value for determining a skip operation when a skip operation command is input from the user. As the skip threshold, for example, a value obtained by adding 30 seconds to the CM average time is set. However, the number of seconds to be added is not limited to 30 seconds and can be set by the administrator. The skip threshold is a threshold for estimating the presence of a CM to which no chapter is assigned at least at the end point at the playback position when the skip operation command is input. A skip operation command is often input at, for example, the start point of a CM. For this reason, when the time length from the playback position to the next chapter when the skip operation command is input is longer than the skip threshold, the playback position is in a CM to which no chapter is assigned at least at the end point. The possibility is shown. In the present specification, the CM does not indicate a CM for advertising one product or the like, but indicates a series of CMs such as a plurality of products broadcast during the main part of the program.

  The skip control unit 14 controls a skip operation when a skip operation command is input during reproduction of program recording data. When receiving a skip operation command, the skip control unit 14 compares the time length from the current playback position to the next chapter with the skip threshold set by the threshold setting unit 13. If the time length from the playback position to the next chapter at the time of inputting a skip operation command is shorter than the skip threshold, the skip control unit 14 skips the playback position to the next chapter. If the time length from the playback position to the next chapter at the time of inputting a skip operation command is shorter than the skip threshold, which is the CM average time + predetermined value, there is a possibility that the CM is between the playback position and the next chapter. Is high. In other words, there is a high possibility that the next chapter is the end point of the CM.

  If the time length from the current playback position to the next chapter is equal to or greater than the skip threshold, it is indicated that there is a possibility that there is a CM to which no chapter is assigned at least at the end point in the section including the current playback position. The skip control unit 14 skips the reproduction position by the CM average time. This is because if the playback position is skipped to the next chapter, the main part of the program may be skipped in addition to the CM in which the chapter is not assigned to the end point. Further, by skipping the CM average time, for example, when the skip operation command is input at the start point of the CM, the playback position is near the end point of the CM to which no chapter is assigned at the end point. Can be moved.

  The skip control unit 14 sets a flag for the next chapter when the time length from the reproduction position to the next chapter when the skip operation command is input is equal to or greater than the skip threshold. When the next chapter has a flag from the playback position when the skip operation command is input next time, for example, the skip control unit 14 does not compare the time length to the next chapter with the skip threshold value. Is skipped for the CM average time. As a result, the processing can be simplified.

(Parameter calculation process flow)
FIG. 3 is an example of a flowchart of the parameter calculation process of the playback device 1. The flowchart shown in FIG. 3 is a part of processing performed by the CPU 101 executing a skip control program stored in the hard disk 106. The flowchart shown in FIG. 3 is started together with the reproduction of program recording data stored in the hard disk 106, for example. However, the present invention is not limited to this, and the flowchart shown in FIG. 3 may be executed, for example, when program recording data is stored in the hard disk 106, or program recording data stored in the hard disk 106 at a predetermined cycle. It may be executed against.

In OP1, the CPU 101 acquires the time length of each section divided into chapters assigned to the program recording data. Next, the process proceeds to OP2.

  In OP2, the CPU 101 extracts a section (CM chapter) corresponding to the CM determination range from the time length of each section. Next, the process proceeds to OP3.

  In OP3, the CPU 101 calculates the average value of the time length of the CM chapter extracted in OP2 as the CM average time. When the CM chapter is not extracted in OP2, the CM average time is set to a set value (for example, a general CM time of 2 minutes). Next, the process proceeds to OP4.

  In OP4, the CPU 101 sets a skip threshold by adding a predetermined value to the CM average time calculated in OP3. For example, the predetermined value is set to 30 seconds. Thereafter, the process shown in FIG. 3 ends.

  The process of OP1 corresponds to a part of the process of the chapter interval acquisition unit 11. The processing of OP2 and OP3 corresponds to part of the processing of the CM average time calculation unit 12. The process of OP4 corresponds to a part of the process of the threshold setting unit 13.

(Specific example of parameter calculation processing)
FIG. 4 is a diagram showing an example of program recording data to which chapters are assigned. In FIG. 4, a band graph shows the start and end of one program recording data. The horizontal axis of the band graph in FIG. 4 indicates time. Further, in the example shown in FIG. 4, the main part of the program is plain and the CM part is indicated by oblique lines.

  The program recording data shown in FIG. 4 is assigned chapters 1 to 10. However, in the example shown in FIG. 4, chapters are not given to all the boundaries between the main program and the CM, and some of them are missing. The chapter is given by the device that generated the program recording data.

  In the example shown in FIG. 4, the chapter interval acquisition unit 11 has 5 minutes 50 seconds between chapters 1-2, 3 minutes 20 seconds between chapters 2-3, 5 minutes 30 seconds between chapters 3-4, chapter 4 2-5 minutes between -5, 8 minutes 10 seconds between chapters 5-6, 11 minutes 50 seconds between chapters 6-7, 12 minutes 20 seconds between chapters 7-8, 3 minutes between chapters 8-9 Then, 4 minutes and 50 seconds are acquired between chapters 9 and 10 (OP1). For example, the elapsed time from the start of program recording data is assigned to each chapter, and the chapter interval acquisition unit 11 acquires the difference in elapsed time assigned to each chapter as the time length of each chapter interval.

  For example, in the program recording data shown in FIG. 4, it is assumed that the CM determination range is set to 2 minutes ± 1 minute. In this case, the CM average time calculation unit 12 extracts a section between chapters 4-5 (2 minutes 30 seconds) and between chapters 8-9 (3 minutes) as a CM chapter (OP2). The CM average time calculation unit 12 calculates an average value of 2 minutes and 45 seconds between the time length between chapters 4-5 (2 minutes 30 seconds) and the time length between chapters 8-9 (3 minutes) as the CM average time. (OP3).

  Next, the threshold value calculation unit 13 sets a skip threshold value (3 minutes and 15 seconds) by adding a predetermined time (30 seconds) to the CM average time (2 minutes and 45 seconds) (OP4).

  From the above, in the program recording data shown in FIG. 4, the CM average time is calculated as 2 minutes and 45 seconds, and the skip threshold is calculated as 3 minutes and 15 seconds.

(Processing flow when inputting a skip operation instruction)
FIG. 5 is an example of a flowchart of the skip control process. The flowchart shown in FIG. 5 is a part of processing performed by the CPU 101 executing a skip control program stored in the hard disk 106. The flowchart shown in FIG. 5 corresponds to part of the processing of the skip control unit 14. The flowchart shown in FIG. 5 starts when a skip operation command is input to the playback apparatus 1 from the user. The instruction for the skip operation from the user is input by, for example, operating the remote controller, pressing an input button for instructing the skip operation, or the like.

  In OP11, the CPU 101 determines whether or not a flag is set for the next chapter. When the flag is set for the next chapter (OP11: Yes), the process proceeds to OP14, and the CPU 101 skips the reproduction position by the CM average time (OP14). If the flag is not set for the next chapter (OP11: No), the process proceeds to OP12.

  In OP12, the CPU 101 compares the time length from the reproduction position to the next chapter at the time of inputting a skip operation command with the skip threshold. If the time length from the reproduction position to the next chapter at the time of inputting a skip operation command is larger than the skip threshold (OP12: Yes), the process proceeds to OP13. If the time length from the current playback position to the next chapter is less than or equal to the skip threshold (OP12: No), the process proceeds to OP15, and the CPU 101 skips the playback position to the next chapter (OP15). Thereafter, the process shown in FIG. 5 ends.

  In OP13, the CPU 101 sets a flag for the next chapter. With this flag, when a skip operation command is input next time in the same section, the processing for OP11 and OP14 is performed for the CM average time without comparing the time length to the next chapter with the threshold (OP12). The position is skipped. Next, the process proceeds to OP14, and the reproduction position is skipped by the CM average time. Thereafter, the process shown in FIG. 5 ends.

(Operation example when skip operation command is input)
FIG. 6 is a diagram illustrating an operation example 1 when a skip operation command is input. FIG. 6 shows a band graph of the same program recording data as FIG. Therefore, in the example shown in FIG. 6, the time length of each section, the CM average time (2 minutes 45 seconds), and the skip threshold (3 minutes 15 seconds) are the same as in the example shown in FIG. In the program recording data shown in FIG. 6, chapter 6 is the start point of the CM, but no chapter is given to the end point of the CM. The time length of the CM where chapter 6 is the starting point is 2 minutes 30 seconds. It is also assumed that no flag is set for any chapter when a skip operation command is input.

  In the first operation example, a case where a skip operation command is input from the user when the reproduction position is chapter 6 will be described.

  In the example shown in FIG. 6, the time length from the input of the skip operation command (chapter 6) to the next chapter 7 is 11 minutes 50 seconds, which is longer than the skip threshold (3 minutes 15 seconds) (OP12: Yes ). Therefore, the skip control unit 14 sets a flag on the chapter 7 (OP13). Further, the skip control unit 14 skips the reproduction position by the CM average time (OP14).

By skipping the playback position by the skip control unit 14, the playback position is a position advanced 15 seconds from the end point of the CM starting from the chapter 6 (CM time 2 minutes 30 seconds, CM average time 2 minutes 45 seconds) For). In this case, for example, the user searches for a desired viewing point by manually rewinding or the like. If the user-desired viewing point is the end point of the CM, in this case, the desired viewing point (CM end point) can be reached by performing a rewind operation for 15 seconds. When processing by the skip control unit 14 is not performed, the playback position is skipped to the chapter 7 when a skip operation command is input in the chapter 6. In this case, the viewing point (CM end point) desired by the user is shifted from 9 minutes 20 seconds. For example, the user performs a rewinding operation for 9 minutes 20 seconds. Therefore, by performing the process by the skip control unit 14, it is possible to reduce the operation time of the user and the time that the user continues to watch the rewind screen.

  FIG. 7 is a diagram illustrating an operation example 2 when a skip operation command is input. FIG. 7 shows a band graph of program recording data after the processing described in FIG. 6 is executed. Therefore, in the example shown in FIG. 7, the time length of each section, the CM average time (2 minutes 45 seconds), and the skip threshold (3 minutes 15 seconds) are the same as the examples shown in FIGS. The chapter 6 is the start point of the CM, but the chapter is not added to the end point of the CM as in FIG. In the program recording data shown in FIG. 7, the chapter 7 is flagged as a result of the processing described in FIG. 6. In FIG. 7, chapters whose chapter numbers are circled are chapters that are flagged.

In the operation example 2, after the process described in the operation example 1, a CM in which no chapter is assigned to the start point and the end point is included between the chapters 6-7, and at the start point of the CM, from the user A case where a skip operation command is input will be described. The start point and the end point of a CM in which no chapter is assigned to the start point and the end point between chapters 6-7 are set as point S.

  In the example shown in FIG. 6, a flag is set in the chapter 7 next to the reproduction position (point S) at the time of inputting a skip operation command (OP11: Yes). Therefore, the skip control unit 14 skips the reproduction position by the CM average time (OP14).

  By skipping the playback position by the skip control unit 14, the playback position becomes a position advanced from the point S by the CM average time (2 minutes 45 seconds). Here, it is assumed that the playback position after skipping is a position that is ahead of point E, which is the end point of the CM. The user searches for a desired viewing point by manually rewinding or the like.

  In the example shown in FIG. 7, when the processing by the skip control unit 14 is not performed, the playback position is skipped to chapter 7 when a skip operation command is input in chapter 6. In this case, a rewinding operation is performed in order to find a viewing point desired by the user (CM end point). However, in the case of the program recording data shown in FIG. 7, there is a high possibility that the user stops the rewinding operation at the point E (CM end point), and the main part existing before the point S is not noticed. There is a possibility of missing a part. As shown in the operation example 2, when the process by the skip control unit 14 is executed, oversight of the main part can be reduced.

  The display screen after skipping may be paused at the playback position after skipping, or may be played back from the playback position after skipping. Further, during the skip operation, for example, the position to which the chapter is assigned and the current reproduction position may be displayed in a band shape at the lower part of the screen of the display unit 110 (for example, FIGS. 6 and 7).

<Operational effects of the first embodiment>
When the time length to the next chapter is longer than the skip threshold, the playback device 1 of the first embodiment skips the playback position by the CM average time, not to the next chapter. Accordingly, even when there is a CM to which no chapter is assigned at the end point, the user can efficiently find the end point of the CM. Here, “efficient” means, for example, that the operation time and the number of operations for rewinding and fast-forwarding are small. Moreover, the time during which the user continues to watch the rewind or fast-forward screen can be shortened, and the burden on the user can be reduced. Also, according to the playback device 1 of the first embodiment, even if there is a CM between which chapters are not assigned at the start point and end point, a part of the main part is overlooked. Can be reduced.

  In the first embodiment, the CM average time and the skip threshold are calculated from chapters including program recording data. Since the CM time varies depending on the type and length of the program, the playback apparatus according to the first embodiment can perform skip control according to the type and length of the program.

<Modification of First Embodiment>
When a skip operation command is input, it may be determined whether or not the time length from the current playback position to the next chapter is longer than the skip threshold before executing the flowchart shown in FIG.

  FIG. 8 is an example of a flowchart of a skip control process according to a modification. The flowchart shown in FIG. 8 is a part of processing performed by the CPU 101 executing a skip control program stored in the hard disk 106. Further, the flowchart shown in FIG. 8 corresponds to a part of the processing of the skip control unit 14. The flowchart shown in FIG. 8 starts when a skip operation command is input to the playback apparatus 1 from the user. The instruction for the skip operation from the user is input by, for example, operating the remote controller, pressing an input button for instructing the skip operation, or the like.

  In OP21, the CPU 101 compares the time length from the reproduction position to the next chapter at the time of inputting a skip operation command with the skip threshold. If the time length from the reproduction position to the next chapter at the time of inputting a skip operation command is longer than the skip threshold (OP21: Yes), the flowchart shown in FIG. 5 is then executed. If the time length from the current playback position to the next chapter is equal to or less than the skip threshold (O21: No), the process proceeds to OP22, and the CPU 101 skips the playback position to the next chapter (OP22). Thereafter, the process shown in FIG. 8 ends.

  According to the flowchart of FIG. 8, even when the flag is set for the next chapter, if the time length from the playback position to the next chapter at the time of inputting a skip operation command is equal to or less than the skip threshold, the playback position is Skipped to next chapter. This is the same as a normal skip operation, and does not give the user a sense of incongruity.

(Operation example when skip operation command is input)
FIG. 9 is a diagram illustrating an operation example 3 at the time of inputting a skip operation command in the modification. FIG. 9 shows a band graph of the same program recording data as FIG. Therefore, in the example shown in FIG. 9, the time length of each section, the CM average time (2 minutes 45 seconds), and the skip threshold (3 minutes 15 seconds) are the same as in the example shown in FIG. In addition, a flag is set on the chapter 7.

  In operation example 3, a case where a skip operation command is input from the user at point X in the middle of the main part and a case where a skip operation command is input from the user at point Y in the middle of the main part will be described.

When a skip operation command is input at point X, in the example shown in FIG. 9, the time length from the input of the skip operation command (point X) to the next chapter 7 is 8 minutes and 10 seconds, and the skip threshold value Longer than (3 minutes 15 seconds) (OP21: Yes). Therefore, the skip control unit 14 executes the flowchart of FIG. 5 and the chapter 7 is flagged (FIG. 5, OP
11: Yes), the playback position is skipped by the CM average time (FIG. 5, OP14).

  When a skip operation command is input at the Y point, in the example shown in FIG. 9, the time length from the input of the skip operation command (Y point) to the next chapter 7 is 2 minutes and 40 seconds, and the skip threshold value Shorter than (3 minutes 15 seconds) (OP21: No). Accordingly, the skip control unit 14 causes the next chapter to skip the playback position (OP22).

  When a skip operation command is input at point X, the flowchart of FIG. 5 is executed, and the processing result is the same as in the first embodiment. On the other hand, when a skip operation command is input at point Y, unlike the first embodiment, the playback position is skipped to the next chapter. Since this is a normal skip operation, the user does not feel uncomfortable.
