  The processing device includes at least one of a subtitle-included video file in which subtitles are superimposed on a video and a subtitle-free video file in which subtitles are not superimposed on a video from a content file for television broadcasting having closed captions. Is generated. Video files generated by the processing device (one or more captioned video files, captionless video files, etc.) are stored in a server that provides information via the Internet.

  The terminal device requests the server for a video file (one or a plurality of captioned video files, captionless video files, etc.). In response to a request from the terminal device, the server provides the terminal device with a video file (one or more captioned video files, captionless video files, etc.). The terminal device processes a video file (one or a plurality of subtitle-included video files, subtitle-free video files, etc.) received from the server, and reproduces subtitle-present video, subtitle-free video, and the like.

  According to the content confirmation system of the present embodiment as described above, if there is a terminal device having a function of connecting to the Internet and a function of processing (decoding or the like) a video file and reproducing the content, the content having the closed caption Can be previewed. In other words, even when there is no dedicated device for playing back content having closed captions, it is possible to preview content having closed captions.

  In the content confirmation system of this embodiment, video files (one or more captioned video files, captionless video files, etc.) are provided via the Internet. The degree of freedom increases. As a result, the efficiency of the confirmation work before broadcasting the content having the closed caption is further improved.

  Hereinafter, the configuration of the processing device and the terminal device of the present embodiment will be described in detail. Note that the hardware configurations of the processing device and the terminal device of the present embodiment are the same as the hardware configurations of the processing device and the terminal device of all the following embodiments.

  First, an example of the hardware configuration of the processing device and the terminal device will be described. Each function provided in each of the processing device and the terminal device of the present embodiment includes a CPU (Central Processing Unit) of an arbitrary computer, a memory, a program loaded into the memory, and a storage unit such as a hard disk for storing the program (the device is previously installed). In addition to programs stored from the shipping stage, storage media such as CDs (Compact Discs) and programs downloaded from servers on the Internet, etc.), hardware and software centering on network connection interfaces Realized by any combination of It will be understood by those skilled in the art that there are various modifications to the implementation method and apparatus.

  FIG. 1 is a block diagram illustrating a hardware configuration of each of the processing device and the terminal device according to the present embodiment. As shown in FIG. 1, each of the processing device and the terminal device includes a processor 1A, a memory 2A, an input / output interface 3A, a peripheral circuit 4A, and a bus 5A. The peripheral circuit 4A includes various modules. Note that the processing device and the terminal device may not have the peripheral circuit 4A.

  The bus 5A is a data transmission path through which the processor 1A, the memory 2A, the peripheral circuit 4A, and the input / output interface 3A transmit / receive data to / from each other. The processor 1A is an arithmetic processing device such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit). The memory 2A is a memory such as a RAM (Random Access Memory) or a ROM (Read Only Memory). The input / output interface 3A is an interface for acquiring information from an input device (eg, keyboard, mouse, microphone, etc.), external device, external server, external sensor, etc., and an output device (eg, display, speaker, printer, mailer). Etc.), an interface for outputting information to an external device, an external server, etc. The processor 1A can issue a command to each module and perform a calculation based on the calculation result.

  Next, the functional configuration of the processing apparatus 10 will be described. FIG. 2 shows an example of a functional block diagram of the processing apparatus 10. As illustrated, the processing apparatus 10 includes a generation unit 11.

  The generation unit 11 generates at least one of one or a plurality of subtitle-included video files and subtitle-free video files from a television broadcast content file having closed captions (hereinafter, “CC-added TV content file”). Generate. For example, the generation unit 11 may generate both a captioned video file and a captionless video file from a TV content file with CC. In addition, the generation unit 11 generates only a captioned video file. In addition, the generation unit 11 may generate only a captionless video file.

  The content file for TV with CC includes a video file in which no caption is superimposed on the video and caption data. FIG. 3 schematically shows an example of the data structure of the content file for TV with CC. The content file for TV with CC is, for example, an MXF (material exchange format) file. As shown in the figure, the content file for TV with CC includes metadata, a video file in which captions are not superimposed on the video (hereinafter sometimes referred to as “original video file”), an audio file, and ancillary data. Can be included.

  The metadata indicates technical parameters of video / audio, information on contents (eg, performers), time code, and the like.

  Ancillary data includes subtitle data. The caption data indicates a character string to be superimposed on the video, a display timing (display start timing and display end timing) of each character string, a display position (position in the video) of each character string, and the like. Note that the caption data may indicate the character string, display timing, display position, and the like for each of a plurality of video formats in which at least one of resolution and aspect ratio is different from each other. Examples of the video format include high definition video (HD), standard definition television (SD), and one seg (mobile).

  The generation unit 11 can transcode (down-convert) the original video file included in the TV content file with CC to generate a subtitle-free video file.

  Moreover, the production | generation part 11 can superimpose a character on the image | video of the original video file contained in the content file for TV with CC, and can trans | transform (down-convert) the said file, and can produce | generate a video file with a caption.

  For example, the generation unit 11 specifies a frame on which each character string is superimposed from among a plurality of frames included in the original video file, based on each character string included in the caption data and the display timing of each character string. And the production | generation part 11 superimposes each character string on the predetermined position (display position of each character string shown by subtitle data) of the specified flame | frame. By performing this process for all the frames on which the character string is superimposed, a video file in which captions are superimposed on the video is generated. Note that the generation unit 11 may generate a caption-included video file for each of a plurality of video formats (eg, HD, SD, one segment) having at least one of resolution and aspect ratio different from each other.

  For example, as illustrated in FIG. 4, the generation unit 11 may generate four video files from one CC-attached TV content file. The number of video files to be generated is not limited to that shown in FIG. For example, as shown in FIG. 5, two video files may be generated from one CC content file for CC. The video format of the captioned video file generated in this case is arbitrary. In addition, although not shown, the generation unit 11 may generate other numbers of video files.

  The content file for TV with CC may be a CM (commercial message) content file or a program content file. Further, the file formats of the captioned video file and the captionless video file are not particularly limited, but examples thereof include MP4.

  The video files (one or a plurality of subtitle-included video files, subtitle-free video files, etc.) generated by the generation unit 11 and the audio files included in the content file for television broadcasting include content identification information (for example, : Content name) and stored in a server that provides information via the Internet. For example, the processing apparatus 10 may transmit information to the server, the information may be stored in the server by other means, or the processing apparatus 10 may be the server. Hereinafter, a server that stores a video file (one or a plurality of subtitle-included video files, subtitle-free video files, etc.) and an audio file in association with content identification information (eg, content name) is referred to as “content providing server”. "

  Next, the functional configuration of the terminal device 20 will be described. FIG. 6 shows an example of a functional block diagram of the terminal device 20. As illustrated, the terminal device 20 includes a transmission unit 21, a reception unit 22, and a reproduction unit 23. The terminal device 20 is, for example, a personal computer, a smartphone, a tablet terminal, or the like, but may be other.

  The transmission unit 21 transmits a content request to the content providing server (external device). In the content request, for example, one content is specified. In response to the content request, the content providing server returns a video file (one or a plurality of subtitle-included video files, subtitle-free video files, etc.) and an audio file associated with the designated content. Examples of a method for providing a moving image file including video and audio include a progressive download method and a streaming method.

  The receiving unit 22 receives a video file (one or a plurality of subtitle-included video files, subtitle-free video files, etc.) and an audio file transmitted from the content providing server.

  The playback unit 23 plays back the specified content using the video files (one or more captioned video files, captionless video files, etc.) and audio files received by the receiving unit 22. As a result, for example, video is displayed via a display, and audio is output via a speaker. When the captioned video file is processed, the captioned video is played. When the captionless video file is processed, the captionless video is played.

  FIG. 7 shows an example of the processing flow of the terminal device 20. In S10, the transmission unit 21 transmits a content request to the content providing server (external device). In the content request, for example, one content is specified.

  In S11, the receiving unit 22 receives a video file (one or a plurality of subtitle-included video files, subtitle-free video files, etc.) and an audio file transmitted from the content providing server in response to the content request in S10.

  In S12, the reproduction unit 23 processes the moving image file (including the video file and the audio file) received in S11, and reproduces the content. When the captioned video file is processed, the captioned video is played. When the captionless video file is processed, the captionless video is played.

  According to the content confirmation system of the present embodiment described above, if there is the terminal device 20 having a function of connecting to the Internet and a function of processing a video file and reproducing the content, the content having the closed caption is previewed. It becomes possible. In other words, even when there is no dedicated device for playing back content having closed captions, it is possible to preview content having closed captions.

  Moreover, in the content confirmation system of this embodiment, since a subtitle-included video file and a subtitle-free video file are provided via the Internet, the degree of freedom for viewing a subtitle-capable video and subtitle-free video is increased. As a result, the efficiency of the confirmation work before broadcasting the content having the closed caption is further improved.

<Second Embodiment>
In the content confirmation system of the present embodiment, the terminal device 20 reproduces content by a characteristic method using one or a plurality of subtitle-included video files and subtitle-free video files. The configuration of the processing apparatus 10 is the same as that of the first embodiment. Hereinafter, the configuration of the terminal device 20 will be described in detail.

  FIG. 8 shows an example of a functional block diagram of the terminal device 20. As illustrated, the terminal device 20 includes a transmission unit 21, a reception unit 22, a reproduction unit 23, and a reception unit 24. The functional configurations of the transmission unit 21 and the reception unit 22 are the same as those in the first embodiment. The playback unit 23 has functions described below in addition to the functions described in the first embodiment.

  The reproduction unit 23 reproduces one or a plurality of captioned videos and captionless videos one by one. The accepting unit 24 accepts a switching input for switching video to be displayed on the screen. Then, the playback unit 23 switches the video to be played back between one or a plurality of captioned videos and captionless videos in accordance with the switching input.

  The receiving unit 24 receives various inputs from the user via various input devices such as a mouse, a keyboard, a touch panel display, a physical button, and a microphone (the same applies to all the following embodiments).

"Switching method 1"
For example, when the playback unit 23 switches from playback of the first video to playback of the second video in response to the switching input, the playback unit 23 starts from the playback stop position of the first video (elapsed time from the beginning of the content) to the second video. Video playback may be started.

  The first video is one of one or more subtitled video and subtitleless video, and the second video is the first video of one or more subtitled video and no subtitle video. It is a different video. The playback stop position may be indicated by an elapsed time from the beginning of the content.

  FIG. 9 shows an example of processing for playback while switching between one captioned video and one captionless video. ts indicates the content start position, and te indicates the content end position. t1 to t4 indicate elapsed time from ts.

  In the case of the illustrated example, first, a captionless video is played. The reproduction start position at this time is ts. Then, the switching input is made when the subtitle-free video is reproduced up to t1. The video displayed by this switching input is switched from a captionless video to a captioned video. Then, the captioned video is reproduced from the time t1. After that, the switching input is made when the subtitle-equipped video is reproduced up to t2. The video displayed by this switching input is switched from the video with caption to the video without caption. The subtitle-free video is reproduced from the time t2. Thereafter, the switching input is performed when the subtitle-free video is reproduced up to t3. The video displayed by this switching input is switched from a captionless video to a captioned video. Then, the captioned video is reproduced from time t3. After that, the switching input is performed when the subtitle-equipped video is reproduced until t4. The video displayed by this switching input is switched from the video with caption to the video without caption. The subtitle-free video is reproduced from the time t4.

  FIG. 10 shows an example of a process of playing while switching between a plurality of captioned videos and one captionless video. ts indicates the content start position, and te indicates the content end position. t1 to t6 indicate elapsed time from ts.

  In the case of the illustrated example, first, a captionless video is played. The reproduction start position at this time is ts. Then, the switching input is made when the subtitle-free video is reproduced up to t1. The video displayed by this switching input is switched from a captionless video to a captioned video (SD). The captioned video (SD) is reproduced from the time t1. Thereafter, the switching input is made when the captioned video (SD) is reproduced up to t2. The video displayed by this switching input is switched from captioned video (SD) to captioned video (HD). The captioned video (HD) is reproduced from the time t2. After that, the switching input is made when the captioned video (HD) is reproduced until t3. The video displayed by this switching input is switched from captioned video (HD) to captioned video (SD). The captioned video (SD) is reproduced from the time t3.

  After that, the switching input is performed when the captioned video (SD) is reproduced until t4. The video displayed by this switching input is switched from the captioned video (SD) to the captioned video (mobile). The subtitle-equipped video (mobile phone) is played back from time t4. After that, the switching input is made when the captioned video (mobile phone) is reproduced until t5. The video displayed by this switching input is switched from the video with caption (mobile phone) to the video without caption. The subtitle-free video is reproduced from the time t5. Thereafter, switching input is performed when the non-captioned video is reproduced up to t6. The video displayed by this switching input is switched from a captionless video to a captioned video (HD). Then, the captioned video (HD) is reproduced from the time t6.

  As a modification of the switching method, when the playback unit 23 switches from playback of the first video to playback of the second video according to the switching input, the playback stop position of the first video (elapsed from the beginning of the content) The reproduction of the second video may be started from a predetermined time before (time).

  FIG. 17 shows an example of the process of the modification. ts indicates the content start position, and te indicates the content end position. t1 to t4 indicate elapsed time from ts.

  In the case of the illustrated example, first, a captionless video is played. The reproduction start position at this time is ts. Then, the switching input is made when the subtitle-free video is reproduced up to t1. The video displayed by this switching input is switched from a captionless video to a captioned video. The subtitle-equipped video is reproduced from the time (t1-q) (the position going back from time t1 by time q). After that, the switching input is made when the subtitle-equipped video is reproduced up to t2. The video displayed by this switching input is switched from the video with caption to the video without caption. Then, the non-captioned video is reproduced from the time (t2-q). Thereafter, the switching input is performed when the subtitle-free video is reproduced up to t3. The video displayed by this switching input is switched from a captionless video to a captioned video. The subtitle-equipped video is reproduced from the time (t3-q). After that, the switching input is performed when the subtitle-equipped video is reproduced until t4. The video displayed by this switching input is switched from the video with caption to the video without caption. The subtitle-free video is reproduced from the time (t4-q).

  The difference between one or a plurality of subtitled video and non-captioned video is “whether or not subtitles are superimposed”, “resolution”, “aspect ratio”, and the like, and the content and content length are the same. For this reason, according to the above playback method of starting playback of the second video from the playback stop position of the first video (eg, the position at which time t has elapsed from the beginning of the content), the presence or absence of subtitles according to the switching input, The subtitle display position, subtitle size, resolution, aspect ratio, and the like are switched, but the content can be seamlessly switched without interruption.

"Switching method 2"
The playback unit 23 may manage the playback stop position (elapsed time from the beginning of the content) for each of a plurality of videos. Then, when the video displayed on the screen is switched by the switching input, the reproduction unit 23 may reproduce the video newly displayed on the screen from the previous reproduction stop position of the video.

  The first video is one of one or more subtitled video and subtitleless video, and the second video is the first video of one or more subtitled video and no subtitle video. It is a different video. The playback stop position may be indicated by an elapsed time from the beginning of the content.

  Here, a specific example of the switching method will be described using an example in which screen display is performed while switching between captionless video and captioned video. First, it is assumed that a non-captioned video is reproduced from ts and a switching input is made at the time of reproduction up to t1. The video displayed by this switching input is switched from a captionless video to a captioned video. Then, the captioned video is reproduced from the time ts. Thereafter, it is assumed that the switching input is made when the captioned video is reproduced up to t′1. The video displayed by this switching input is switched from the video with caption to the video without caption. The subtitle-free video is reproduced from the time t1. t1 and t′1 may be the same or different. Thereafter, it is assumed that the switching input is made when the non-captioned video is reproduced up to t2. The video displayed by this switching input is switched from a captionless video to a captioned video. Then, the captioned video is reproduced from the time t′1. Thereafter, the same processing is repeated.

  Note that, in the case of the above example, the playback unit 23 performs both switching from one video to the other video and vice versa in response to a user switching input. As a modified example, the playback unit 23 may perform switching from one video to the other according to a switching input from the user, and may perform the reverse switching automatically.

  Here, a specific example of the modification will be described by taking as an example a case where screen display is performed while switching between a captionless video and a captioned video. First, it is assumed that a subtitle-free video is reproduced from ts, and the user's switching input is made at the time of reproduction up to t1. The video displayed by this switching input is switched from a captionless video to a captioned video. Then, the captioned video is reproduced from the time ts. After that, when the subtitle-equipped video is reproduced up to t1, the playback unit 23 automatically switches the video displayed on the screen from the subtitle-equipped video to the subtitle-free video. The subtitle-free video is reproduced from the time t1. Thereafter, it is assumed that the user's switching input is made when the non-captioned video is reproduced up to t2. The video displayed by this switching input is switched from a captionless video to a captioned video. Then, the captioned video is reproduced from the time t1. Thereafter, when the subtitle-equipped video is reproduced up to t2, the reproducing unit 23 automatically switches the video displayed on the screen from the subtitle-equipped video to the subtitle-free video. The subtitle-free video is reproduced from the time t2. Thereafter, the same processing is repeated.

"Switching method 3"
The playback unit 23 may play back the second video from the beginning of the content when switching from playback of the first video to playback of the second video in response to the switching input. That is, when the video displayed on the screen is switched by the switching input, the reproducing unit 23 may reproduce the video newly displayed on the screen from the beginning of the content.

  The first video is one of one or more subtitled video and subtitleless video, and the second video is the first video of one or more subtitled video and no subtitle video. It is a different video. The playback stop position may be indicated by an elapsed time from the beginning of the content.

  According to the content confirmation system of this embodiment described above, it is possible to realize the same operational effects as those of the first embodiment. Moreover, according to the terminal device 20 of this embodiment, it can reproduce | regenerate, switching one or some subtitle | video with a subtitle | subtitle, and a non-subtitle | video. For this reason, it is possible to check these images continuously while comparing them with each other.

<Third Embodiment>
In the content confirmation system of this embodiment, the terminal device 20 reproduces content by using a characteristic method different from that of the second embodiment, using one or a plurality of captioned video files and subtitle-free video files. The configuration of the processing apparatus 10 is the same as that of the first embodiment. Hereinafter, the configuration of the terminal device 20 will be described in detail.

  FIG. 8 shows an example of a functional block diagram of the terminal device 20. As illustrated, the terminal device 20 includes a transmission unit 21, a reception unit 22, a reproduction unit 23, and a reception unit 24. The functional configurations of the transmission unit 21 and the reception unit 22 are the same as those in the first embodiment. The playback unit 23 has functions described below in addition to the functions described in the first embodiment.

  The reproduction unit 23 simultaneously reproduces one or more captioned videos and no captioned videos in time synchronization, and displays one or more captioned videos and captionless videos side by side. The receiving unit 24 receives a playback control input. The playback unit 23 similarly controls (with the same content) all of one or a plurality of captioned videos and non-captioned videos according to the playback control input. Examples of the contents of the reproduction control include, but are not limited to, pause, stop, fast forward, rewind, skip (moving the reproduction position to a predetermined position), speed reproduction (reproduction faster than normal), and the like.

  FIG. 11 schematically shows an example of a screen displayed on the display during content reproduction by the method of the present embodiment. In the example shown in the figure, three captioned videos and one captionless video are simultaneously displayed on the screen. These are played back in time synchronization. That is, the elapsed times from the beginning of the content all match. Note that the content and content length of one or a plurality of captioned video and non-captioned video are the same.
