Description

  The present invention relates to a segment metadata production management server and a segment metadata production system in which production of segment metadata describing information about a section of a video to be broadcast is produced by a plurality of producers.

  In the server-type broadcast that is scheduled to start broadcasting soon, the broadcast video and information, and the video and information acquired by communication are stored in the receiver, and various services for using the stored video and information are provided. Is done. One of these various services is to use segment metadata, which is information about video segments, to watch only a part of the stored video, or to extract only the highlights of the program and watch the digest There is something that can be done.

Conventionally, as a method of automatically generating segment metadata, a method using automatic recognition technology such as video and audio (for example, refer to Patent Document 1) or a method using a program configuration table and video switching information (for example, non-discrimination). Patent Document 1) has been proposed.
Patent Publication 2004-86124 Kazuhiko Takabayashi, Kenjiro Kai: “Examination of utilization of video switching information as metadata”, 2001 Annual Conference of the Institute of Image Information and Television Engineers, August 2001

  However, in the above conventional method of generating segment metadata using automatic recognition technology, segment metadata may not be extracted with high accuracy if speech recognition is not performed appropriately. In addition, in the conventional method for generating segment metadata using the program configuration table and video switching information, segment metadata cannot be generated from a viewpoint not related to the program configuration table.

  Therefore, in the past, with regard to the segment metadata produced by the method by which the creator manually creates segment metadata while referring to the video, or by the method using the automatic recognition technology or the program configuration table and the video switching information, It was necessary for the producer to check and correct it.

  By the way, some programs have a large number of segment metadata to be produced, confirmed and corrected in one program, and in that case, it is difficult to perform the work alone. In particular, when creating, confirming, and correcting segment metadata in real time, it is necessary to share the work among multiple producers, and duplication and omissions in segment metadata creation, confirmation, and correction work Could occur.

  Also, unlike conventional video / audio editing and subtitle production, segment metadata may include one video segment in multiple segment metadata. When time division is performed by the number of creators, an imbalance may occur, such as the load on a specific producer becoming high at a specific timing, or the load on a specific producer becoming low.

  The present invention has been made in view of the above-described conventional circumstances, and is capable of producing, confirming, or correcting a plurality of segment metadata without causing duplication or omission. An object is to provide a production management server and a segment metadata production system.

And input means for inputting program configuration information;
Based on the information specifying the occurrence order, the segment metadata to be produced is classified into array type segment metadata that can be arranged in time series and event type segment metadata that occurs irregularly, and the classified Array-type segment metadata is created for each producer as the segment metadata to be produced, confirmed, or modified based on information related to the production of the segment metadata including past production history information, production number and production person information. Assigned assignment means to assign,
Notifying means for notifying the segment metadata production / confirmation / correction terminal for producing, confirming or modifying the segment metadata of the allocated array type segment metadata and the event type segment metadata It is characterized by that. According to this configuration, segment metadata that can be produced in chronological order can be appropriately assigned to the set production person based on past production history information, so there is no duplication or omission, Multiple segment metadata can be created, confirmed or modified in parallel by multiple personnel.

  The segment metadata production management server of the present invention is the production, confirmed, or modified after the responsible assignment means receives a production, confirmation, or modification completion notification from the segment metadata production / confirmation / correction terminal. The remaining segment metadata excluding the segment metadata that has already been allocated is reassigned. According to this configuration, the remaining segment metadata can be appropriately assigned to the set production personnel in sequence, so multiple segment metadata can be efficiently handled by multiple personnel without duplication or omissions. Can be produced, confirmed and corrected.

  The segment metadata production management server of the present invention is characterized in that the information specifying the generation order is script information used at the time of program production. According to this configuration, based on the script information, it is possible to accurately organize the segment metadata to be produced in chronological order. Therefore, it is possible to efficiently produce multiple segment metadata for multiple persons in charge. Can be confirmed and corrected.

  According to the present invention, a plurality of persons in charge can efficiently execute production, confirmation, or correction of segment metadata.

  FIG. 1 is a diagram showing a configuration of a segment metadata production system in the embodiment of the present invention. The segment metadata production system includes a segment metadata production management server 10, a segment metadata production / confirmation / correction terminal 20, and a LAN 30 that connects the server and the terminal.

  The segment metadata production management server 10 further includes a segment metadata production management unit 100, a communication unit 110, a database 120, an input unit 130, and the like. The segment metadata production management unit 100 further includes a charge assignment unit 101 and a notification unit 102.

  The segment metadata production management unit 100 generates segment metadata to be produced based on information 131 related to segment metadata production input from the input unit 130 and past production history information stored in the database 120. Categorized into segment metadata whose occurrence timing can be specified (that is, segment metadata that can be arranged in time series) and segment metadata whose occurrence timing cannot be specified (that is, segment metadata that occurs irregularly) To do. Further, the assignment assignment unit 101 determines assignment of which production person in charge produces, confirms, or corrects at which segment metadata production / confirmation / correction terminal for the segment metadata whose generation timing can be specified. . The notification unit 102 notifies each segment metadata production / confirmation / correction terminal 20 of the determined assignment.

  The communication unit 110 communicates with the segment metadata production / confirmation / correction terminal 20. The database 120 stores past production history information, rules on a program to be described later, and the like.

  The segment metadata production / confirmation / correction terminal 20 includes a plurality of client terminals (client terminals 20a to 20d in the example of FIG. 1). The client terminal further includes a display unit 200, an input unit 210, and a notification. Part 220.

  The display unit 200 displays segment metadata for production or confirmation / correction. The input unit 210 performs input for producing, confirming, and correcting segment metadata. The notification unit 220 notifies the segment metadata production management server at the start or completion of production or confirmation / modification of segment metadata.

  FIG. 2 is a flowchart showing an operation procedure of the segment metadata production management server according to the embodiment of the present invention. First, in the segment metadata production management unit 100 of the segment metadata production management server 10, information related to segment metadata production, that is, a production person / production terminal, a type of program, segment metadata scheduled to be produced, and program configuration information Is input from the input unit 130 (step S100).

  Here, the program configuration information is, for example, information regarding the configuration of news items and broadcast schedule start / end times of items in the case of news programs, and in the case of a baseball broadcast program, first order, first / second , Information about the composition of the game, such as a record player.

  Next, the segment metadata production management unit 100 selects the corresponding past from the past production history information and the rule information on the program stored in the database 120 based on the input information about the segment metadata production. Production history information and rule information on the program are acquired (step S101).

  Here, the rule information on the program is information for specifying the order of occurrence of events, that is, the order of occurrence of segment metadata. For example, in the case of a baseball broadcast program, information on baseball game rules is applicable. Therefore, when the input “program type” is baseball, past production history information and rule information regarding baseball are acquired.

  FIG. 3 is a diagram conceptually showing past production history information accumulated in the database 120. The past production history information includes information such as a program type, segment metadata production contents, production time, production person, segment metadata confirmation / modification time, confirmation / modification person, and the like.

  Next, the segment metadata production management unit 100, based on the program type, the program configuration information, and the rule information on the program, the segment metadata that is scheduled to be produced is segment metadata whose occurrence timing can be specified. Whether or not (step S102).

  If it is segment metadata whose occurrence timing can be specified, it is managed as “ordered segment metadata” (step S103), and if it is segment metadata whose occurrence timing cannot be specified, it is managed as “event type segment metadata”. (Step S104).

  Further, it is determined whether or not the segment metadata to be produced is segment metadata that requires confirmation / correction work (step S105). If confirmation / correction work is required, “confirmation / correction segment” is determined. It is managed as “metadata” (step S106).

  Next, the segment metadata production management unit 100 determines whether or not a segment metadata production start notification has been received (step S107). If the segment metadata production management unit 100 receives the start notification, it notifies each segment metadata production / confirmation / correction terminal to that effect. Is notified (step S108). In addition, the assigning / assigning unit 101 of the segment metadata production management unit 100 calculates the scheduled time required for production or confirmation / correction of the ordered segment metadata based on the past production history information, and based on the calculation result, Determine the allocation of segment metadata that the production manager is responsible for. The segment metadata to be produced or confirmed / corrected is listed for each person in charge of production (step S109).

  Here, the process of assigning segment metadata for each person in charge will be specifically described.

  In the baseball example described above, first, it can be determined from the rule information acquired from the database 120 whether or not the plurality of segment metadata to be produced is “order type”. For example, in the input program configuration information, the segment metadata relating to the batter of a player registered as a batter in an arbitrary batting order is determined to be an order type based on the rule information (that is, if the batting order is known) , The order of segment metadata regarding the batter of each inning batter is automatically determined). On the other hand, for example, segment metadata related to a home run hit by an arbitrary player cannot be predicted in advance, and is therefore managed as “event type” segment metadata.

  Next, the segment metadata classified as “order type” can be assigned to individual production managers based on the metadata production history information of past baseball programs acquired from the database 120. For example, it is possible to know which production manager has created, confirmed, and modified what type of segment metadata in the past, and how much time it took to perform such work. Depending on the most efficient allocation method (for example, assign segment metadata of the type assigned in the past to the same person as much as possible, or segment metadata with a large amount of work from the person with the shortest work time in the past. A method (such as setting to assign them in order) may be appropriately set in advance.

  Next, the notification unit 102 of the segment metadata production management unit 100 classifies the ordered segment metadata (including confirmation / correction segment metadata) determined to be assigned in step S109 and the event type segment metadata in step S102. A list of the segment metadata is notified to the corresponding segment metadata production / confirmation / correction terminal 20 for each person in charge of production (step S110).

  Next, the segment metadata production management unit 100 determines whether or not a production / confirmation / modification completion notification is received from the segment metadata production / confirmation / correction terminal 20 (step S111). When the completion notification is received, the assigned allocation unit 101 of the segment metadata production management unit 100 returns to step S108 again, and the segment metadata that has been produced or confirmed / corrected and the segment metadata that is being produced or confirmed / modified Allocation is performed again for the remaining segment metadata except for.

  Next, FIG. 4 is a flowchart showing an operation procedure of the segment metadata production / confirmation / correction terminal according to the embodiment of the present invention. First, the segment metadata production / confirmation / correction terminal 20 determines whether or not the segment metadata scheduled to be produced is received from the segment metadata production management server 10 (step S200). The order-type segment metadata, event-type segment metadata, and confirmation / correction segment metadata are separately displayed on the terminal screen (step S201).

  FIG. 5 is a diagram schematically showing a screen display in the segment metadata production / confirmation / correction terminal 20. As shown in the figure, the segment metadata displays separately the order-type segment metadata scheduled to be in charge of production and the confirmation / correction segment metadata, and event-type segment metadata that is not classified for each person in charge of production. In addition, the sequential segment metadata and confirmation / correction segment metadata scheduled for production will be the next segment to be produced, confirmed, or modified so that the creator can easily determine the segment metadata to be produced, confirmed, or modified. The metadata is highlighted (step S202).

  Next, the segment metadata production / confirmation / correction terminal 20 determines whether or not the person in charge of production has started production or confirmation / correction of segment metadata (step S203). When the production or confirmation / modification of segment metadata is started, the notification unit 220 notifies the segment metadata production management server 10 of a production / confirmation / modification start notification (step S204).

  Further, the segment metadata production / confirmation / correction terminal 20 determines whether or not the production person in charge has completed the production or confirmation / correction work of one segment metadata (step S205). 220 notifies the segment metadata production management server 10 of completion of production or confirmation / correction work (step S206).

  As described above, according to the segment metadata production management system of this embodiment, segment metadata that can be produced in order in chronological order is appropriately applied to the set production personnel based on past production history information. Since they can be assigned, a plurality of segment metadata can be simultaneously produced (concurrently) or confirmed / corrected by a plurality of persons in charge without duplication or omission. In addition, after receiving the notification of completion of production or confirmation / modification, the remaining segment metadata is reassigned in order by reassigning the remaining segment metadata excluding the segment metadata that has been produced or confirmed / modified. It can be appropriately assigned to the set production person in charge.

  In the above-described embodiment, information related to segment metadata production is input to the segment metadata production / confirmation / correction terminal 20 that can be connected to the input unit 130 of the segment metadata production management server 10 via the LAN 30. It may be performed from the unit 210.

  In the above embodiment, when the input “program type” is a drama or a variety program, any information such as a script script that can be used to grasp the progress of the program can be May be used as “rules” information.

  The present invention has an effect that segment metadata can be efficiently created, confirmed and corrected without causing missing or overlapping operations, and segment metadata describing information about a section of a broadcast video is described. This is useful for a segment metadata production management server, a segment metadata production system, and the like in which a plurality of producers share the production.
