Description

  The present invention relates to a technique for recording content such as a television broadcast program on a recording medium.

Various contents such as TV broadcast programs include a part representing the contents of the program (hereinafter referred to as “main part”) and a part representing an advertisement by a company (hereinafter referred to as “commercial part”). It is common. As a technique for recording this type of content on a recording medium such as a DVD (Digital Versatile Disc), a technique has been proposed in which only the main part is selectively recorded on the recording medium excluding the commercial part (for example, a patent). Reference 1). According to this technology, the user can selectively view only the main part by playing back the content recorded on the recording medium.
JP 2003-18538 (paragraphs 0086 to 0090 and FIGS. 5 and 6)

  However, under this technique, the content from which the commercial part is excluded is recorded on the recording medium, so that even if the user subsequently desires to view the commercial part, it can no longer be viewed. On the other hand, if the content is recorded on the recording medium without removing the commercial part, the commercial part can be viewed, and the commercial part can be reproduced by fast-forwarding if necessary. However, it is difficult to accurately fast-forward only the commercial portion by manual operation. In other words, it is difficult for the user to accurately recognize the end point of the commercial part from the image being played back by fast-forwarding, and the part of the main part following the commercial is played back by fast-forwarding. Can occur.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a content processing apparatus and a program that can selectively reproduce a main part and a commercial part.

  In order to solve this problem, a content processing apparatus (recording apparatus or recording / playback apparatus) according to the present invention includes content acquisition means for acquiring content in which a main part and a commercial part are alternately arranged in time series, and content acquisition Boundary detection means for detecting the boundary between the main part and the commercial part of the content acquired by the means, content classification means for dividing the content into chapters at the boundary detected by the boundary detection means, and content classification means Recording means for recording the recorded content on a recording medium. The “chapter” in the present invention is a portion that is a unit designated as a reproduction target in the content. In other words, when any chapter is designated at the time of content reproduction, the reproduction is started from the head portion of the chapter. Therefore, in the present invention, “dividing content into chapters” means processing so that, when using (for example, reproducing) content recorded on a recording medium, a portion to be used can be specified in units of chapters. It means to do. For example, the content classifying unit generates chapter data indicating the position of the boundary detected by the boundary detecting unit. With this configuration, when a chapter is specified during content playback, the boundary position is specified based on the chapter data, and thereby the chapter to be played back is specified. The chapter data generated by the content classifying unit is recorded on the recording medium together with the content by, for example, the recording unit.

  In a preferred aspect of the present invention, attribute acquisition means for acquiring data indicating the attribute of the main part of the content is further provided, and the boundary detection means includes the attribute of the main part indicated by the data acquired by the attribute acquisition means and the commercial part. The boundary is detected based on the difference from the attribute. The attribute of the main part or the commercial part is, for example, an image or sound format included in the content. The attribute acquisition unit may receive electronic program guide data corresponding to the content acquired by the content acquisition unit from the server via a network, and acquire data indicating the attribute from the electronic program guide data.

  The present invention is also specified as a program for causing a computer to function as a content processing apparatus. That is, the program (content processing program) according to the present invention includes a content acquisition unit that acquires a content in which a main part and a commercial part are alternately arranged in time series, and the content acquired by the content acquisition unit. A boundary detection means for detecting a boundary between the main part and the commercial part, a content classification means for dividing the content into chapters at the boundary detected by the boundary detection means, and a content classification means It functions as a recording means for recording content on a recording medium. This program is provided to the computer by distribution via a network such as the Internet, and is provided in a form stored in various recording media represented by an optical disc and installed in the computer.

  According to the present invention, the main part and the commercial part are divided into chapters, and then the content is recorded on the recording medium. Therefore, the main part or commercial part can be selectively played back by appropriately specifying chapters at the time of playback, or the main part and commercial part can be played back alternately according to the intended content. And the commercial portion can be selectively reproduced.

<A-1: Functional Configuration of Embodiment>
FIG. 1 is a block diagram showing a functional configuration of a content processing apparatus according to an embodiment of the present invention. As shown in the figure, the content processing apparatus 100 includes a content acquisition unit 11, a boundary detection unit 21, a content classification unit 22, a recording unit 41, and a reproduction unit 42. Among these, the content acquisition unit 11 is a unit for acquiring content including moving images and sound. As shown in FIG. 2, the content acquired by the content acquisition unit 11 has a main part and a commercial part (“CM part” shown in FIG. 2) each including a moving image and sound. In general, commercials are included in contents (programs) provided to viewers by television broadcasting. Of the content, the part representing the original content of the program is the main part, and the part representing the content of the commercial is the commercial part. In one content, the main part and the commercial part are alternately arranged on the time axis. The content acquired by the content acquisition unit 11 is output to the boundary detection unit 21 and the content classification unit 22.

  The boundary detection unit 21 shown in FIG. 1 is a unit for detecting the boundary between the main part and the commercial part in the content supplied from the content acquisition unit 11. In FIG. 2, the position of this boundary is indicated by the symbol “B”. The boundary detection means 21 in this embodiment detects the boundary between both parts based on the difference between the audio format of the main part (hereinafter referred to as “audio format”) and the audio format of the commercial part. The audio formats include, for example, a stereo format in which audio from a plurality of channels is output in stereo, a monaural format in which audio is output in monaural, and a bilingual format in which audio in different languages is output for each channel. In general television broadcasting, the audio of the commercial part is in stereo format, and the audio of the main part is often in monaural format or bilingual format. Therefore, the boundary detection means 21 according to the present embodiment detects the boundary between the part of the content in which the audio format is the stereo format and the part in the monaural format or the bilingual format, and uses this boundary as the main part and the commercial. Identifies the boundary with the part.

  Next, the content classification unit 22 shown in FIG. 1 is a unit for dividing the content into a plurality of chapters based on the boundary detected by the boundary detection unit 21. A chapter is a section serving as a unit designated as a reproduction target in content. For example, when an instruction to skip a chapter is given while a certain chapter is being played, the playback point moves to the beginning of the next chapter. As described above, the boundary detection means 21 detects the boundary between the main part and the commercial part. Therefore, according to the content classification means 22, each of the main part and the commercial part included in the content is one as shown in FIG. It will be classified as a chapter. The content classifying unit 22 in this embodiment classifies content into chapters by generating data indicating the position of the boundary detected by the boundary detecting unit 21 (hereinafter referred to as “chapter data”). The chapter data in the present embodiment indicates the time when the beginning of each chapter starts to be reproduced when the contents are reproduced in the order of chapters (see FIG. 3). This time is based on the time when the content starts to be reproduced from the beginning. The chapter data is output from the content classification unit 22 to the recording unit 41 together with the content output from the content acquisition unit 11.

  The recording means 41 acquires the chapter data and the content (including both the main part and the commercial part) from the content classification means 22 and records them on the recording medium 4a. A typical example of the recording medium 4a is a DVD. However, various media such as other optical disks (for example, CD-R and CD-RW), magnetic disks, and magneto-optical disks may be employed as the recording medium 4a. The chapter data is recorded on the recording medium 4a so as to be included in the chapter list. As shown in FIG. 3, this chapter list is a table in which codes (here, chapter numbers) uniquely assigned to each chapter are associated with chapter data generated for the chapter.

  On the other hand, the reproducing means 42 shown in FIG. 1 reads out the content from the recording medium 4a and outputs it. The content output from the reproducing means 42 is supplied to an output device such as a display device or a sound emitting device (for example, a speaker). The reproduction means 42 can change the reproduction point as appropriate by referring to the contents of the chapter list. For example, when an instruction to skip a chapter is given when a chapter is being played, the playback means 42 shifts the playback point to the beginning of the chapter next to the chapter being played back. If only the main part is selected as a chapter to be played back in advance, the playback means 42 moves the playback point to the beginning of the next main part chapter at the timing when the playback of the main part chapter ends. (That is, skip the chapter of the commercial part between the main part).

<A-2: Hardware Configuration of Embodiment>
Next, FIG. 4 is a block diagram showing a hardware configuration of the content processing apparatus 100 according to the present embodiment. As shown in the figure, the content processing apparatus 100 includes a tuner 1a, a demodulation circuit 1b, a control device 2, a storage device 31, an input device 32, an output device 33, a recording / reproducing device 4, and a communication device 5. The demodulating circuit 1 b, the storage device 31, the input device 32, the output device 33, the recording / reproducing device 4, and the communication device 5 are connected to the control device 2 via the bus B.

  The tuner 1a selectively outputs the frequency component corresponding to the channel selection by the user among the television broadcast waves received by the antenna. On the other hand, the demodulating circuit 1b demodulates the signal output from the tuner 1a to acquire content (video signal and audio signal) and output the content to the control device 2. As described above, the content acquisition unit 11 shown in FIG. 1 is realized by the tuner 1a and the demodulation circuit 1b.

  The control device 2 is a device for controlling each part of the content processing device 100, and a CPU (Central Processing Unit) that realizes various functions by executing a program and a ROM (Read that stores a program executed by the CPU). Only Memory) and RAM (Random Access Memory) used as a work area by the CPU. The storage device 31 is a device for storing a program executed by the control device 2 and data used in association with the execution of the program, and is, for example, a hard disk device. In this storage device 31, a main part and a commercial part of content are divided into chapters, recorded on the recording medium 4a, and a program for reproducing the content recorded on the recording medium 4a (hereinafter referred to as "content processing program"). Is stored). The boundary detection means 21 and the content classification means 22 shown in FIG. 1 are realized by the control device 2 executing a content processing program.

  The input device 32 is, for example, a keyboard or a mouse, and outputs a signal corresponding to an operation given to the operator by the user from the bus B to the control device 2. The input device 32 includes an operation element (hereinafter referred to as “skip button”) 32a for skipping a chapter being reproduced. On the other hand, the output device 33 includes a display device and a sound emitting device. Among these, the display device includes a display unit such as a CRT (Cathode Ray Tube) or a liquid crystal display panel, and displays a moving image of content under the control of the control device 2. The sound emitting device is, for example, a speaker or a headphone, and outputs sound of content under the control of the control device 2.

  The recording / reproducing device 4 has a function of recording the content supplied from the control device 2 on the recording medium 4a, and a function of reading the content recorded on the recording medium 4a and outputting the content to the control device 2. That is, the recording means 41 and the reproducing means 42 shown in FIG. Note that the recording / reproducing apparatus 4 may be included in the content processing apparatus 100 or may be configured separately from the content processing apparatus 100.

  Next, the communication device 5 is means for communicating with the server 7 via a network 8 such as the Internet. The server 7 has a storage device 71. In the storage device 71, data representing an electronic program guide called EPG (Electronic Program Guide) (hereinafter referred to as “EPG data”) is stored for each content to be broadcast on television. Each EPG data includes various types of information related to content. The communication device 5 outputs the EPG data received from the server 7 via the network 8 to the control device 2.

  FIG. 5 is a diagram schematically showing the contents of EPG data prepared for one content. As shown in the figure, the EPG data includes header information D1, broadcast channel information D2, broadcast date and time information D3, content information D4, and attribute information D5. Of these, the broadcast channel information D2 includes the broadcast channel number (version) of the content and the name of the broadcast station (station). The broadcast date and time information D3 includes the time (start) and the time (end) at which the broadcast of the content is started, in addition to the date (year, month, date) at which the content is broadcast. The content information D4 includes the title of the content (program-title) and various types of information (program-subtitle) related to the content such as subtitles, outlines of contents, and performers.

  On the other hand, the attribute information D5 includes information indicating the attribute of the content. This attribute includes the audio format of the main part of the content. In the example of FIG. 5, it is assumed that the code “2” indicating the bilingual format is included in the attribute information D5. If the audio format of the main part is monaural, the code “M” is included in the attribute information D5. Furthermore, as shown in FIG. 5, when text broadcasting is performed on the content, a code “character” indicating that is included in the attribute information D5. The control device 2 detects the boundary between the main part and the commercial part based on information representing the audio format in the attribute information D5 included in the EPG data. The control device 2 can also provide the user with various information regarding the content by displaying the content of the EPG data on the display device.

<A-3: Operation of Embodiment>
Next, the operation of the content processing apparatus 100 shown in FIG. 4 will be described. When a predetermined operation is performed on the input device 32 by the user, the control device 2 reads the content processing program stored in the storage device 31 and sequentially executes it. Hereinafter, an operation when an operation for recording content on the recording medium 4a is performed (FIG. 6) and an operation when an operation for reproducing the content recorded on the recording medium 4a is performed (FIG. 6). 7) and will be described.

(1) Content recording process (FIG. 6)
First, when recording content on the recording medium 4a, the user selects a desired broadcast channel by appropriately operating the input device 32, and specifies the content to be recorded on the recording medium 4a. The control device 2 acquires EPG data corresponding to the content designated by the user from the server 7 by the communication device 5 and stores it in the RAM (step Sa1). On the other hand, the tuner 1a and the demodulation circuit 1b sequentially output each part of the content obtained from the television broadcast wave. The control device 2 acquires the content portion from the demodulation circuit 1b via the bus B and stores it in the RAM (step Sa2). Next, the control device 2 determines whether or not the content part acquired in step Sa2 includes a boundary between the main part and the commercial part (step Sa3). More specifically, the control device 2 first specifies the audio format of the main part from the attribute information D5 of the EPG data acquired in step Sa1. Secondly, the control device 2 uses a part of the content acquired in step Sa2 from a part having the same format as the previously specified voice format (for example, a main part in a bilingual format) to a different audio format. A boundary at which a part is switched (for example, a commercial part in a stereo format) or a boundary at which a voice format is switched to this is detected.

  When the boundary is detected in step Sa3, the control device 2 specifies the time of the boundary calculated from the start time of the content, and generates chapter data representing the time. And the control apparatus 2 produces | generates the record which consists of the chapter data and the number allocated to the chapter which immediately follows the boundary, and memorize | stores it in RAM (step Sa4). On the other hand, when the boundary is not detected in step Sa3, the control device 2 shifts the process to step Sa5 without passing through step Sa4.

  In step Sa5, the control device 2 outputs the content acquired in step Sa2 to the recording / reproducing device 4. Furthermore, when the record containing chapter data is produced | generated in step Sa3, the control apparatus 2 outputs this record to the recording / reproducing apparatus 4 with a content. The recording / reproducing device 4 records the content supplied from the control device 2 on the recording medium 4a, and adds a record to the chapter list when a record is supplied together with the content.

  Next, the control device 2 determines whether or not to end the content recording process on the recording medium 4a (step Sa6). Specifically, the input device 32 is given an operation for ending the recording process when the end time of the content included in the EPG data has come (that is, when the recording process has been completed for all parts of the content). If it is determined that the recording device should be terminated, the control device 2 terminates the execution of the content processing program. On the other hand, when it is determined that the recording process should not be terminated yet (for example, when the end time of the content has not yet arrived), the control device 2 shifts the processing to step Sa2 and performs the same for the next part of the content. Repeat the process.

(2) Content playback processing (FIG. 7)
Next, when reproducing the content from the recording medium 4a, the user designates any content recorded on the recording medium 4a by appropriately operating the input device 32. The control device 2 outputs an instruction to the recording / reproducing device 4 that the first chapter of the content designated by the user should be read from the recording medium 4a. In response to this instruction, the recording / reproducing apparatus 4 reads the contents from the recording medium 4a in order from the first chapter and outputs them. Thereby, the control apparatus 2 acquires each part of a content sequentially from the recording / reproducing apparatus 4 (step Sb1). Further, the control device 2 outputs the content acquired in step Sb1 to the output device 33 to reproduce the content (step Sb2). Specifically, the control device 2 outputs data representing an image of the content to the display device and outputs data representing the sound to the sound emitting device. As a result, the moving image of the content is displayed on the display device, and sound is emitted from the sound emitting device.

  Next, the control device 2 determines whether or not the skip button 32a has been operated by the user (step Sb3). If it determines with having operated here, the control apparatus 2 will select the chapter immediately after the chapter currently read out as reproduction | regeneration object (step Sb4). On the other hand, when determining that the skip button 32a has not been operated, the control device 2 shifts the processing to step Sb5 without passing through step Sb4.

  In step Sb5, the control device 2 determines whether or not the content reproduction should be terminated. Specifically, when the reproduction process is completed for all parts of the content or when an operation for ending the reproduction process is given to the input device 32, the control device 2 determines that the reproduction process should be terminated. The execution of the content processing program is terminated. On the other hand, when it is determined that the playback process should not be finished yet (for example, when the playback process has not been completed for all parts of the content), the control device 2 shifts the process to step Sb1 to play back the content. repeat. Here, when the skip button 32a is operated by the user, the next chapter is selected in step Sb4. Therefore, in the processing of step Sb1 immediately after that, the newly selected next chapter is reproduced from the top. Start to be.

  As described above, according to the present embodiment, the main part and the commercial part of the content are divided as chapters. For example, a user who does not want to view the commercial part is in a stage where playback of the commercial part is started. By operating the skip button 32a, the playback point can be immediately shifted to the next main part. Alternatively, if the skip button 32a is operated every time reproduction of the main part is started, only the commercial part can be selectively viewed. In addition, when the skip button 32a is operated, playback is started from the beginning of each chapter, so that the problem of fast forwarding to a part of a desired chapter by the fast forward operation is avoided. On the other hand, since the main part and the commercial part are recorded together on the recording medium 4a, if the user desires to view the commercial part, the commercial part is viewed unless the skip button 32a is operated. be able to. Thus, according to the present embodiment, the main part and the commercial part can be selectively reproduced.

  Although FIG. 7 illustrates the operation when each chapter is appropriately skipped, the chapter to be played back and the playback order of each chapter may be specified prior to the playback of the content. For example, data defining the playback order of each chapter included in the content (for example, “Video Title Set Information” for controlling playback of the content; hereinafter referred to as “navigation data”) is stored in advance in association with the content. May be. Under this configuration, when the earliest chapter specified as a playback target by the navigation data has been played back, playback of the next chapter specified by the navigation data is started. If there is a chapter (for example, a commercial part) that is not specified by the navigation data, the chapter is automatically skipped. Further, prior to recording the content on the recording medium 4a, the user is prompted to select a command such as “play only the main part” or “play only the commercial part”, and the chapter (only the main part only) corresponding to the selected command is prompted. Alternatively, navigation data that selectively designates only the commercial portion as a reproduction target may be generated and recorded together with the content on the recording medium 4a. According to this configuration, the user can continuously view only the main part (or only the commercial part) without requiring an operation for skipping the commercial.

  In the present embodiment, EPG data including information related to content is acquired from the server 7 via the network 8, and the boundary between the main part and the commercial part is detected based on the attribute information D5 included in the EPG data. The Therefore, the reliability of the boundary detection can be improved as compared with the configuration in which the boundary is detected according to the operation by the user.

<B: Modification>
The embodiment described above is merely an example, and various modifications can be made to this embodiment without departing from the spirit of the present invention. Specifically, the following modifications can be considered.

(1) In the above embodiment, in order to divide the content into chapters, the configuration in which the time at which the playback of each chapter should be started is generated as the chapter data. However, the content of the chapter data is not limited to this. . For example, an address at which the head portion of each chapter in the recording medium 4a is stored may be used as the chapter data. Further, in the above-described embodiment and each modified example, the configuration for creating the chapter list in order to divide the main part and the commercial part is illustrated, but the configuration for dividing the content into chapters is not limited thereto. For example, when the content is recorded on the recording medium 4a in step Sa5 in FIG. 6, chapter data (flag) indicating that the beginning portion of the main portion and the beginning portion of the commercial portion of the content are the beginning portion of the chapter. It is good also as a structure which adds. On the other hand, when reproducing the content recorded in this way, if it is detected in step Sb3 in FIG. 7 that the skip button 32a has been operated, the chapter next to the chapter that was being reproduced at that time is determined based on the chapter data. A configuration may be adopted in which a search is started and reproduction is started from the searched chapter in step Sb1 immediately after that. As described above, in the present invention, it is sufficient if the content is recorded on the recording medium so that the portion to be reproduced can be specified in units of chapters of the content recorded on the recording medium, and the content is divided into chapters. It doesn't matter how you do it.

(2) In the above-described embodiment and modification, the configuration in which each of the main part and the commercial part is divided as one chapter is illustrated, but the method of dividing the content is not limited to this. For example, as shown in FIG. 8, the main part and the subsequent commercial part may be grouped into one chapter. This configuration is realized by detecting, as a boundary, only a portion where the audio format is switched from the stereo format to the bilingual format or the monaural format in the above embodiment. Alternatively, as shown in FIG. 8 with parentheses, all boundaries between the main part and the commercial part are detected, and only the boundary when transitioning from the commercial part to the main part is selected as the chapter boundary. You may make it do. Even in these configurations, when the commercial button belonging to one chapter is being played, if the chapter button is operated, the playback point moves to the beginning of the main part belonging to the next chapter. Only the main part can be selectively viewed by appropriately operating the button 32a.

(3) The method for detecting the boundary between the main part and the commercial part in the content is not limited to the method using the difference in the audio format. For example, the user operates the input device 32 at the timing of the boundary between the main part and the commercial part during content reproduction, and the control device 2 detects the time point when this operation is detected as the boundary between the main part and the commercial part. It is good also as a structure. Further, the EPG data attribute information D5 includes information specifying the image format of the content, and is based on the difference between the image format of the main part indicated by this information and the image format of the commercial part determined in advance. Thus, a configuration may be adopted in which the boundary between both parts is detected. Examples of the image format include an NTSC (National TV Standards Committee) format, an EDTV (Extended Definition Television) -I format, and an EDTV-II format. Under this configuration, the boundary between the main part and the commercial part is detected according to whether the image is in the clear vision format or the wide clear vision format. Further, a specific identifier (flag) may be included in the boundary between the main part and the commercial part of the content, and the time point when this identifier is detected may be detected as the boundary between the main part and the commercial part. Furthermore, a boundary between the main part and the commercial part may be detected by combining a plurality of methods. In addition, a configuration that specifies an audio format or an image format without using EPG data may be employed. For example, the audio format or the image format may be specified from the received television broadcast wave. In the configuration for detecting the boundary between the main part and the commercial part without using the EPG data, the configuration for acquiring the EPG data is not necessarily required.

(4) In the above-described embodiment and each modification, the case where one content is recorded on the recording medium 4a is exemplified, but a plurality of contents may be recorded on one recording medium 4a. Of course. When a plurality of contents are recorded together with the chapter list on the recording medium 4a, the chapter lists of all the contents ("chapter list group" shown in FIG. 9) are stored in a single storage area as shown in FIG. Alternatively, as shown in FIG. 10, a configuration may be adopted in which a chapter list of the content is added to the head portion of each content (that is, a configuration in which chapter lists are distributed and recorded).

(5) In the above embodiment and the modification, the configuration for acquiring content from a television broadcast wave has been illustrated, but the content provided via the Internet, the content broadcast by CATV (Cable Television), or the broadcasting satellite The broadcast content may be acquired and recorded in the recording medium 4a. Moreover, in the said embodiment, although the structure which acquires EPG data from the server 7 was illustrated, the acquisition destination of EPG data is not restricted to this. For example, it is good also as a structure which acquires EPG data with a content from a digital television broadcast wave.

(6) In the above-described embodiment and each modified example, as shown in FIG. 6, the configuration for acquiring EPG data when recording content on the recording medium 4 a is illustrated, but EPG data is acquired in advance. It is good also as a structure to keep. For example, under a configuration in which the user can specify the broadcast time of the content and reserve the recording thereof, the EPG data may be acquired and stored in the storage device 31 at the time of the reservation.

It is a block diagram which shows the functional structure of the content processing apparatus which concerns on embodiment of this invention. It is a figure which shows the structure of the content paying attention to the main part and the commercial part. It is a figure which shows the specific content of a chapter list.
