Description

  The present invention relates to a technology for reserving and editing content, and more particularly to a technology for automatically correcting a time lag of acquired content and efficiently editing various content including live content. Things.

  A point at which a scene is switched by turning on / off a camera in a video or a joint of video editing (fade, wipe, etc.) is called cut. A shot refers to a section between cuts. As a technique for detecting a cut and extracting a shot or the like, there is a technique described in Patent Document 1, for example.

  A set of shots and cuts whose recording interval is within a predetermined time is defined as one “topic”. In general, topics are meaningful moving images or still images. For example, if a CM is included in one program, the CM is one of the topics. In this specification, an element that constitutes a content such as a shot is referred to as “element content”.

  Patent Literature 1 describes a cut-out method and a shot detection method that can detect temporally slow scene (shot) changes and enable uniform real-time processing of an image including flash light. A plurality of cuts and shots can be detected by using the technique described in Patent Literature 1. Although desired program content can be created based on the detected cuts and shots, in the prior art, this editing is often performed manually, which is troublesome.

In addition, there has been a demand for a technology for efficiently creating and editing program contents by combining various contents including live contents.

  An object of the present invention is to provide an editing apparatus for editing a program content configured by combining a plurality of contents, the storage means for storing program progress information, and an existing content based on content information input according to the program progress information. An existing content acquisition unit for acquiring the live content reservation start time and the reservation end time, and a live content acquisition unit for acquiring the live content based on the reservation start time and the reservation end time, based on the program progress information, Means for combining the existing content and the live content and outputting the program content as program content.

  ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to acquire a live content automatically by a live reservation based on program progress information, to incorporate it into a program including existing content, and to edit a desired program. The content information is, for example, topic information described in the embodiment.

  The editing device may further include a change unit that changes the program progress information based on a time length of the existing content acquired by the existing content acquisition unit or a time length of the live content acquired by the live content acquisition unit. And the changing means changes the program progress information with reference to the priority of each content constituting the program content.

  Therefore, it is possible to create a program having a configuration suitable for the situation by changing the program progress information.

  The existing content acquisition unit may retrieve content attached to the existing content by searching for metadata attached to the existing content based on the input content information. In this way, the desired existing content can be automatically obtained.

The editing apparatus may further include a correction unit configured to correct a start portion or an end portion of the acquired content and make the content suitable for use in the program content. Can be automatically corrected.
The correction means includes: a start time or an end time of a time frame of one content in the program progress information; and a start time or an end time of at least one element content among the acquired element contents constituting the one content. Based on the above, the acquired one content may be corrected for each element content unit. Further, the correction means can correct the one content in units of the element content using one correction pattern of a plurality of correction patterns. Further, the correction unit corrects the one content using a correction pattern selected by the user, and the editing device displays the correction pattern selected by the user as identification information of the user and the correction pattern. The correction pattern may be stored in association with information on the used content, and using the stored correction pattern information, a means for recommending a specific correction pattern when the user creates new program content may be provided.

Further, since a plurality of correction patterns can be used, it is possible to perform editing more suitable for the purpose.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows a configuration of a system according to an embodiment of the present invention. As shown in FIG. 1, the system according to the embodiment of the present invention includes an editing device 1, an indexing device 2, and an encoding processing device 3. An outline of the operation of the present system will be described with reference to the flow of FIG.

(Overview of the system)
In the editing device 1, first, a user inputs program progress information on a program configuration (step S1). This program progress information is stored in the storage device of the editing device 1, and can be changed and updated as needed. As a result, the user can use the program progress information that has already been saved, and can reduce the burden of creating new program progress information. The program progress information is the basis of the program configuration, and includes information on the time frame of each topic constituting the program and information on the priority of each topic. Live content and existing content are automatically combined according to the program progress information.

  Next, the user inputs topic information for a plurality of topics constituting the program based on the program progress information (step S2). The topic information is information about the topic, for example, a live or content ID, a live or content name, time information, a topic summary, and the like.

  Next, live insertion reservation and existing content acquisition are performed according to the operation from the user (step S3). In the existing content acquisition, the content matching the time length in the topic information and the program progress information input by the user is acquired by metadata search. In this case, it is assumed that indexing of existing content (processing such as shot identification) has already been performed.

  Based on the live insertion reservation, the encoding processing device 3 performs the encoding process on the live content, and the indexing device 2 performs the indexing process on the encoded live content (step S4). Note that the indexing process refers to performing a process such as identification of a shot.

  The encoded video encoding file (* .asf) and the scene analysis information (* .xml) of the indexed content are sent to the editing device 1. If the indexing process of the existing content has not been performed at the time of step S3, the indexing process of the existing content is also performed at step S4, and the metadata search for the existing content is performed after step S4.

  The editing device 1 performs editing according to the program progress information (step S5). That is, according to the program progress information, the acquired contents (topics) are combined into a program content. At this time, the topic is automatically corrected for the time frame in the program progress information. More specifically, correction processing such as removing unnecessary portions is performed from live content or content acquired as a topic by metadata search, and content used in program content is cut out and incorporated into the program. In this specification, the term “content” is used to mean both live content and existing content unless otherwise specified.

  As described later, the above correction is performed according to a correction pattern selected from a plurality of correction patterns. Which correction pattern to use can be automatically determined by the editing apparatus 1 or can be selected by the user. Further, by providing the user with editing functions such as deletion, rearrangement, selection of thumbnails, and the like, unnecessary shots in the topic, the user can also edit in detail.

  Thereafter, the intended edited program content is output (step S6). As one form of output, it is possible to incorporate a Web page (* .html) into a predetermined homepage template, transfer it to a server, and immediately publish the edited program content to the Web.

  In the configuration shown in FIG. 1, each of the editing device 1, the indexing device 2, and the encoding processing device 3 is obtained by installing a program for executing the processing described in the present embodiment on a general computer. realizable. Further, the editing device 1, the indexing device 2, and the encoding processing device 3 can be realized by one computer, or any two of them can be realized by one computer. Each of these computers may be remotely located and connected to a network.

  Further, the program for performing the processing according to the present embodiment includes a computer-readable recording medium such as an FD (floppy (registered trademark) disk), an MO, a ROM, a memory card, a CD-ROM, a DVD, and a removable disk. And can be stored and distributed. Further, the program can be provided through a network such as the Internet or e-mail.

(Details of the editing device 1)
Next, the configuration of the editing apparatus 1 will be described in detail with reference to FIG. As shown in FIG. 3, the editing apparatus 1 according to the present embodiment generates program progress information in response to input of information on which program progress information is based, and stores a program progress information creating unit 10 for storing the program progress information in a storage device. It has a program progress information management unit 11 for updating and managing the received program progress information, and a topic information collection unit 12 for inputting topic information.

  The editing device 1 also has a situation determination unit 13. The situation determination unit 13 holds the content of the program progress information in the scheduling unit 14, and the time length of the content acquired based on the live content or the topic information is longer than the time length of the corresponding topic in the initially set program progress information. In such a case, the program progress information management unit 11 is notified of, for example, extending the time length of the topic in the program progress information according to the priority of the topic. In addition, as a result of extending the time length of a topic with a higher priority, a process for deleting the time frame of a topic with a lower priority from the program progress information or shortening the time length of the topic is also performed.

  Further, the editing device 1 has a topic information synthesis unit 15 for acquiring topics constituting the program content. The topic information synthesis unit 15 has a content matching processing unit 16 and a metadata search unit 17. The content matching processing unit 16 performs a process of extracting a content that matches the input topic information as a topic. More specifically, the content matching processing unit 16 passes the input topic information to the metadata search unit 17, and the metadata search unit 17 searches for metadata in the target content based on the topic information, and The part is passed to the content matching processing unit 16. Further, the content matching processing unit 16 has a content reservation insertion unit 18 for reserving and acquiring live content, and a priority processing unit 19 for processing the prioritized topics.

  The priority processing unit 19 operates in cooperation with the situation determination unit 13. For example, when the time length of a high-priority topic increases and the time length of a low-priority topic needs to be shortened, the content corresponding to the low-priority topic is determined based on information input in advance. For example, only a specific scene or the like is obtained using the metadata search unit 17. Further, when the situation determination unit 13 detects that the time length of a certain topic is different from the program progress information, the priority processing unit 19 displays a screen for changing the priority input in the program progress information, and It is also possible for the user to change the priority.

  Further, the editing device 1 has an editing unit 20 and an output unit 21. The editing unit 20 includes a correction unit 22 that corrects a shot to be incorporated into a time frame of the program progress information in a unit of a shot in accordance with a predetermined correction pattern, and a correction pattern display unit that displays a plurality of correction patterns for the user to select. 23, a correction pattern storage unit 24 that stores the correction pattern selected by the user in association with the user and the content type, and a statistical processing unit 25 that performs statistical processing on the stored correction pattern. And a teaching unit 26 for teaching a user a recommended correction pattern when correcting a specific content. The editing unit 20 has an editing function unit 27 for manually or automatically editing topics such as deleting unnecessary scenes, rearranging topics, and selecting thumbnails.

  The output unit 21 is a functional unit for outputting the edited program content, and includes a homepage screen creating unit 28 for selecting a template incorporating the program content created according to the program progress information and creating a homepage. The editing device 1 also has a time correction unit 29 for adjusting the time between the devices, and a clock unit 30 for time synchronization between the editing device 1 and the indexing device 2.

  Hereinafter, the operation of the editing apparatus 1 shown in FIG. 3 will be described with reference to the sequence chart of FIG. In the sequence chart of FIG. 4, the part of the editing device 1 is called an editing system, and the part of the indexing device 2 and the encoding processing device 3 is called a generation system.

  In the live reservation, since the time set in the editing device 1 is used for live capturing by the indexing device 2, first, the time adjustment (time synchronization) between the editing device 1 and the indexing device 2 is performed by the clock unit 30. This is performed (step S11).

  When the information (start time, end time, etc. of the time frame of each topic) that is the basis of the program progress information is input to the program progress information creating unit 10, and the program progress information is created based on this information (step S12), A screen for inputting topic information corresponding to the program progress information is displayed. The user inputs topic information of a topic to be inserted into a corresponding time frame in the program progress information (step S13). When the topic is live content relayed from a studio or the like, the user inputs the corresponding topic information (information for specifying the live content), the reservation start time of the live, and the reservation end time. Note that the live content includes not only true live content but also live content (such as VOD content) stored on a tape or the like. Note that what is stored on a tape or the like is also called pseudo live content.

  Subsequently, for the existing content, a metadata search for the existing content is performed based on the topic information, and a desired topic is extracted from the content (step S14). For the live content, a live reservation is made based on the input information.

  The above metadata search process is an existing technology, and can be realized by performing a matching search between metadata attached to the content to be searched and metadata of the input topic information. The metadata is, for example, a content ID, a content title, date and time (including the IN and OUT time zones), a summary, a keyword, a copyright-related information such as a watermark, a content outline, and the like.

  As the input of the topic information, various information can be input. For example, each topic information for a plurality of topics as shown in FIG. 5 is input using a user interface shown as an example in FIG. It is possible.

  In the example shown in FIG. 5, topics 1, 3, and 4 are contents obtained from existing content files, and topic 2 is content obtained by live reservation. As shown in FIG. 7A, when all topic information is input based on the program progress information, content (topic) having a predetermined time length corresponding to each topic information is extracted (FIG. 7B). ). In addition to the program configuration shown in FIG. 5, a program configuration having a tree structure as shown in FIG. 8 may be used. In addition, a program configuration including a combination of only existing contents or a combination of only live contents can be adopted.

  Note that the flow of time in the program progress information is relative. For example, the start time of the first topic is set to 0, and the subsequent time frame (start time, end time) is represented by the elapsed time from that time frame. In the case of live content, reservation and acquisition are performed at the actual time, but on the program progress information, the start and end of the live content are expressed by the relative time. That is, the actual reservation start time corresponds to the start time on the program progress information (this may be called the reservation start time), and the actual reservation end time is the end time on the program progress information (this is the reservation end time). In some cases). In the case of existing content, for example, the start portion of the acquired content is applied to the relative time of the program progress information in accordance with the start of the time frame corresponding to the content. Alternatively, the start point of the acquired content may be placed a predetermined number of shots in time before the start time of the time frame corresponding to the content.

  In FIG. 4, when the live reservation ends, the capture of live content including several shots immediately before the live reservation start time and several shots immediately after the reservation end time is automatically started based on the input reservation start time. That is, the indexing device 2 captures live content via the encoding processing device 3 (steps S16 and S17), and the indexing device 2 performs indexing processing such as shot detection on the encoded live content. (Step S18).

  When the loading is completed (step S19), the video data (* .asf) and the index data (* .xml) of the indexed content are sent from the indexing device 2 to the editing device 1. Topics are generated from the created indexing file.

  Next, editing is performed (step S20). In the editing apparatus 1, topics obtained from existing content and live content are combined according to program progress information. Further, an automatic selection process of a thumbnail image for each topic is performed. The thumbnail image reflects the result of the scene analysis by indexing, and automatically selects a frame suitable for the topic outline.However, the one with the longest shot may be selected, or another method may be used. You may. The editing apparatus 1 updates the program progress information according to the acquired time length of the topic, corrects the topic, and the like.

  Regarding this correction, especially in the case of live, in actual operation, the live may not have started from the reservation start time, so the live content taken in by the indexing device 2 by specifying the reservation start time is included in the program content. May not be appropriate as content used in Therefore, in order to appropriately extract a topic as live content, it is necessary for the editing unit 20 to correct this shift. In addition, for example, there is a case where a performer closes his or her eyes in the first part of a video, and correction is performed except for a shot including such a video. Further, for example, a correction is made with the first shot in which the performer emits sound as the start shot. In the editing apparatus 1 according to the present embodiment, this correction can be automatically performed, or the edited image can be displayed to the user in shot units, and the user can perform correction in shot units. Whether the correction is performed automatically or the user performs the correction while looking at the editing screen can be selected, for example, when inputting topic information. Further, there is a method of correcting a plurality of patterns, and a user can select a desired correction pattern. Furthermore, it is also possible to statistically process correction patterns used by the user in the past and automatically select a correction pattern, or present a recommended correction pattern to the user.

  This correction is performed not only for live content but also for existing content as needed. In other words, if the content extracted from the existing content by metadata search or the like remains, for example, the beginning or end of the content may be inappropriate for adopting as a topic. Is automatically removed.

  After the correction is completed, a homepage screen is generated and output (step S21). That is, the VOD program content is output to the output screen shown in FIG. 9 using the output style sheet of the HTML file. It is also possible to upload and upload a WMT file to create and output a home page as shown in FIG.

  In the series of processes described above, automatic updating of program progress information and correction of topics will be described.

(Automatic update of program progress information)
First, automatic updating of program progress information will be described. As described above, the program progress information includes time frames of a plurality of topics. In addition, the priority is input in association with the frame of each topic in the program progress information.

  Here, when a topic that matches the topic information input according to the program progress information is obtained, the situation determination unit 13 compares the time length corresponding to the topic in the program progress information with the time length of the extracted topic. If there is a difference between the two time lengths, the program progress information management unit 11 is notified to reduce or expand the time frame corresponding to the topic in the program progress information, and the program progress information management unit 11 Make changes. However, the priority of the topic is considered.

  For example, as shown in FIG. 11, when topic 1 has the highest priority and topic 4 has the lowest priority, if the content of topic 1 is longer than the initially set time length in the program progress information, The time length in the program progress information of the topic 1 is increased. Since the overall time length of the program content in the program progress information is substantially constant, as a result of increasing the time length of topic 1, the time length allocated to other topics decreases. Therefore, in the case of FIG. 11, the topic 4 with the lowest priority is deleted. If the topic 1 is not long enough to delete the topic 4, the time length of the topic 4 is appropriately reduced. In this case, the topic 4 is configured such that only a specific scene in the target content is extracted in shot units so as to match the reduced time length. What scenes are extracted when the time length is reduced can be set when topic information is input.

(Topic correction)
Next, a method of topic correction in shot units will be described with reference to FIG. This correction method can be applied whether or not the program progress information is automatically updated. The target topic for which the program progress information has been automatically updated does not go out of the time frame of the program progress information, but there is a video portion that is not suitable for use, for example, at the end of the topic within the frame. In such cases, the correction is effective from the viewpoint of deleting it. Also, if the program progress information is not automatically updated, the time length of the acquired topic may be longer or shorter than the originally set time frame of the program progress information. The correction is also effective. Further, since the correction is performed on a shot-by-shot basis, the correction can be performed efficiently.

  First, an outline of this correction method will be described with reference to FIG. FIG. 12 shows an example of live content. Assume that the time frame (reservation start time-reservation end time) in the program progress information is AB, and the desired live scenes in the content actually acquired by the generation system are shot C, shot D, and shot E. . In this case, in the correction method of the present invention, a shot that includes the start time of a shot (also referred to as a start point) between the reservation start time and the reservation end time is adopted as a topic. In other words, a shot having a start point after the reservation start time and having a start point closest to the reservation start time and a shot having a start point before the reservation end time and having a start point closest to the reservation end time The shot up to the shot having the point is adopted. Hereinafter, even when the content is not live content, the start time of the time frame in the program progress information is referred to as a reservation start time, and the end time is referred to as a reservation end time.

  In the case of FIG. 12A, since the head times of the shots C and D are between the start time and the end time in the reservation, the shots C and D are adopted, but the head time of the shot E is included in the reservation time. Not adopted. The above correction may be performed automatically, or the user may be presented with an image in shot units to select a shot to be adopted. For example, when it is empirically known that a shot straddling the reservation start time is not an appropriate shot, the above automatic correction is particularly effective.

  If the general correction in units of frames is performed manually without using the above method, a large number of frames are included in the shifted part as shown in FIG. It is necessary to make corrections while confirming each one, and the corrections require a lot of time and labor.

  On the other hand, as shown in FIG. 12C, by using the correction method of the present invention, the correction can be automatically performed in units of shots, so that the correction time can be greatly reduced as compared with the case of performing correction in units of frames.

  By the above-mentioned correction, in addition to the topic extracted first, the topic can be extracted at an appropriate break by being approximately adapted to the time length of the reservation start time-reservation end time. In addition, for example, the shot x in FIG. This is also effective from the viewpoint that when there is a possibility that a video in which the performer has closed eyes may be automatically deleted.

(About correction pattern)
The correction can be performed by various methods other than the method shown in FIG. FIG. 13 exemplifies a correction method for eight patterns including the method shown in FIG. In each pattern, the first shot and the last shot adopted as a topic are shown. In each shot, a black circle indicates the start point of the shot, and a white circle indicates the end point of the shot. Further, x attached to a black or white circle indicates a point of interest (start point or end point). As shown in the figure, (a) to (d) focus on the start point of the shot, and (e) to (h) focus on the end point of the shot.

  In the pattern of FIG. 13B, shots having a start point before the reservation start time and shots having a start point before the reservation end time from shots having the start point closest to the reservation start time, Shots up to the shot having the start point closest to the reservation end time are adopted. In (c), a shot having a start point after the reservation start time and having a start point closest to the reservation start time is a shot having a start point after the reservation end time and closest to the reservation end time. The shots up to the shot having the starting point are adopted. In (d), a shot having a start point before the reservation start time and having a start point closest to the reservation start time is a shot having a start point after the reservation end time and having a start point after the reservation end time. Employ shots up to the shot with the closest starting point.

  (E) to (h) correspond to those obtained by replacing “start point” in (a) to (d) with “end point”. For example, in (e), a shot having an end point after the reservation start time and a shot having an end point closest to the reservation start time is a shot having an end point before the reservation end time, and The shots up to the shot having the closest end point are adopted.

  In each of the above correction patterns, a shot whose start point or end point is closest to the reservation start time or the reservation end time is used, but a shot closest to a plurality of shots may be used instead of the closest shot. For example, when the shot closest to the third on the start time side is used, for example, a shot as shown in FIG. 14 is employed in the pattern (b). That is, a shot having a start point before the reservation start time and a shot having a start point closest to the reservation start time and a shot having a start point before the reservation end time and Take the shots up to the shot with the closest starting point (= first).

  For example, after editing (or when inputting topic information), the user selects which correction pattern to use for each topic. In addition, the user can select a correction pattern while viewing the editing screen, and specify the distance (what number) between the start point and the end point from the reservation start time or the reservation end time. Then, the editing apparatus 1 performs the correction using the correction pattern based on the user's selection.

  The automatic correction can be performed, for example, according to the flow shown in FIG. The example of FIG. 15 is an example of the correction pattern shown in FIG.

  First, a correction pattern selected by the user is obtained. If the correction pattern is the pattern (a) in FIG. 13, the processing according to the flow of the pattern (a) is performed. In the flow of the pattern (a), first, a reservation start time is obtained (step S32). Then, after the reservation start time, the head position of the shot closest to the reservation start time is acquired (step S33). If the start position of the shot cannot be obtained, the process ends (step S35). If the start position has been acquired, it is checked whether the start position is within the end time (step S36). If it is not within the end time, the process ends. If it is within the end time, the shot having the head position is adopted as the shot in the content of the program (step S37), and the process returns to step S33 to acquire the head position of the next shot temporally later. Then, the above processing is repeated.

  In addition to the processing described above, a start point closest to the reservation end time is obtained, and a shot of the start point closest to the reservation start time after the reservation start time is obtained. A process of adopting a shot up to a shot may be used. The same processing is performed for other patterns.

  Further, in the flow of FIG. 15, if a time obtained by subtracting a predetermined time (for example, the average of the shot time length) from the reservation start time is newly set as the reservation start time instead of the reservation start time, the pattern (b) in the pattern (b) This can be a correction processing flow. Similarly, in the flow of FIG. 15, by setting a time obtained by adding a predetermined time from the reservation end time to the new reservation end time, the processing flow of the pattern (c) can be obtained. Processing from such a viewpoint can be performed on other patterns.

  Further, in addition to the above-described correction using the correction pattern, the correction can be automatically performed using the rule shown in FIG. That is, when there is a reservation start time between the start point and the end point of the shot, the one that is closer to the reservation start time is selected from the start point and the end point. If the start point is selected, a shot having the start point is adopted. If the end point is selected, the next shot after the shot including the end point is adopted as the first shot. Similarly, at the reservation end time, a start point and an end point that are closer to the reservation end time are selected.

  In addition, in order to delete a shot including a video in which the performer has closed eyes in the video start portion, the video in which the performer has open eyes is stored in the editing apparatus 1, and similar images are stored using the video. Perform an image search to detect the first shot including the video with the performer's eyes open from the reservation start time or from a time before the reservation start time by a predetermined time, and adopt the shot as the start shot It is also possible.

  Further, from the viewpoint of adopting a shot including a video in which the voice of the performer has started as a start shot, from a reservation start time, or from a time a predetermined time before the reservation start time, the audio intensity is set to a predetermined threshold. It is also possible to detect the first shot that includes the portion that exceeds, and use that shot as the start shot.

(Automatic selection of correction pattern)
The editing apparatus 1 can automatically select a correction pattern and perform correction based on the correction pattern selected by the user in the past. In addition, the automatically selected pattern can be presented to the user as a recommended correction pattern, and can be confirmed by the user. The presentation of the recommended correction pattern may be performed when the topic information is input, or may be performed in an editing scene. Hereinafter, a process of automatically selecting a correction pattern will be described.

  For example, it is assumed that a certain user creates a program having the topic configuration shown in FIG. 17 for the first time, and the correction pattern selected by the user in each topic is as shown in FIG. This correction pattern information is stored in the correction pattern storage unit 23 together with the user ID and topic information corresponding to each topic. Then, when the user next creates a program, the correction unit 22 refers to the information stored in the correction pattern storage unit 23 so that the topic related to the topic information stored in the correction pattern storage unit 23 For, the same correction pattern as the correction pattern used previously for the topic is automatically selected. Then, correction is performed using the correction pattern. Alternatively, the correction pattern display unit 23 displays the correction pattern. When the correction pattern is displayed, the user may use the correction pattern as it is or may change it to another correction pattern.

  In addition, as shown in FIG. 18, correction patterns in a plurality of program creations by a user are stored and statistical processing is performed, so that a correction pattern can be automatically selected when a new program is created. . For example, in a plurality of correction pattern selections, for a topic related to a specific content, if the specific correction pattern is the largest, the specific correction pattern is selected for the topic related to the specific content.
