JP4401220B2 - Highlight scene extraction device and highlight scene distribution system - Google Patents

Description

Regardless of professionals and amateurs, there is a strong need to see baseball hitting scenes, scolding scenes, and fine play catching scenes even during matches. In addition, there are many needs for people who do not have enough time to watch all the games and want to see only such scenes.
In order to meet such needs, the present invention distributes a highlight scene extraction device that extracts various highlight scenes of players in baseball (including sports such as softball and the like) and the extracted highlight scene. About the system.

As a program editing and sending system for extracting and sending highlight scenes in sports broadcasts and the like, the one described in Patent Document 1 has been proposed.
The outline of the system described in Patent Document 1 will be described with reference to FIG.
In this system, in the task of designating the IN point (video start point) and OUT point (video end point) of a highlight scene in sports broadcasting etc., the automatic scene division function ( The candidate scene list is displayed by the function of detecting scene switching and dividing the scene), and then the operator determines one point to set the highlight scene.
That is, as shown in FIG. 8A, a scene change is detected from a video to create a candidate scene list, the operator confirms this scene list, sets an IN point, and extracts a highlight scene.
In the example of FIG. 8 (b), the video from when the batter enters the batter box until the first hit is divided into scenes, and the operator sets the OUT point when the play result is confirmed. Referring to this scene list, the IN point of the highlight scene is set and the highlight scene is extracted.
As described above, in the case of using the live video in baseball, the OUT point of the video is first set when the hitting result or the like is confirmed, and the IN point is selected from the candidate scene list. Select and set the highlight scene.
Japanese Patent Laid-Open No. 11-8824

However, with this method, it is difficult to set the IN point and OUT point of the highlight scene while viewing the live video. This is because the OUT point of the highlight scene can be set for the first time when the hitting result is known, and then the highlight scene is seen separately from the live video of the ongoing game. This is because the IN point is set.
Thus, in order to set a highlight scene by the conventional method, it is necessary to set the IN point on a screen different from the live video. For this reason, in the above system, an operator different from the person who checks the current game situation is required. In addition, since setting the IN point requires time to look over the candidate scene, it is difficult to distribute the highlight scene immediately after the result of hitting or the like is confirmed.
The present invention has been made to solve the above-mentioned problems, and it is possible to easily extract a highlight scene in baseball while watching the current game situation and to distribute the extracted highlight scene. An object of the present invention is to provide a highlight scene extraction device and a highlight scene distribution system.

In order to solve the above problem, in the present invention, the video time length is determined based on the play result such as the batting result, and the time point that goes back by this video time length from the OUT point is defined as the IN point, and from the IN point to the OUT point. Are extracted as highlight scenes.
Therefore, the play result and the time length of the extracted video are associated in advance. In the case of hitting results, the pitching time is set from the pitcher's pitching time and the running time from the batter to the base where the batter advances. For example, assuming that the pitching time is ts and the running time between troughs is tr, the video time length when the hit result is a hit is “ts + tr”, the video time length when the second hit is “ts + 2 × tr”, and the like. In the case of running alone, the video time length is set from the running time from the original kite to the advanced kite.
Then, the OUT point of the highlight scene is determined from the time when the result such as the hit result is fixed, the IN point is determined from the video time length associated with the result and the OUT point, and the highlight scene is extracted. The correspondence between the play result and the time length of the extracted video may be stored in a correspondence table, and the video time length may be obtained with reference to the correspondence table.
If the OUT point and the play result such as the hit result are set manually, the extraction and distribution of the highlight scene can be performed by inputting only the result of the advancement state as the hit result and the time that becomes the OUT point. It can be done automatically.
For this reason, it is possible to create and distribute a highlight scene only by paying attention to the live video during the game without re-examining the previous video in order to set the IN point.
On the other hand, an electronic tag such as an RFID tag is attached by a player, and the electronic tag reading means is installed on the heel, and the player's play result and OUT point are set based on the read electronic tag information and the read time. May be.
In this case, since the result of hitting and the OUT point can be set from the time on the player's base, batter information, etc., the highlight scene can be automatically created.
Therefore, according to the present invention, a baseball highlight scene can be efficiently created without placing a burden on the operator.

According to the present invention, a highlight scene in baseball can be easily extracted even when it is manually performed while viewing the current game situation. Also, by using a network such as the Internet, the extracted highlight scene video can be distributed to the viewer.
Furthermore, if an electronic tag is attached to the player and an electronic tag reading means is installed on the heel or the like, a highlight scene can be automatically extracted and distributed.

When the game starts, the shooting means 12 shoots batters, runners and the like, and encodes the video by the encoding processing unit 11b.
Hereinafter, a case where a batter hits a hit will be described as an example.
As described above, the electronic tag is attached to the player, and the electronic tag information is read by the electronic tag information reading devices 10a to 10d provided in the respective cages and sent to the measuring device control means 13.
As shown in FIG. 2B, when the player enters the batter box, the electronic tag information reading devices 10a to 10d read the electronic tag attached to the player by the electronic tag information reading device 10a. The attribute of batter B is associated with the unique information. When the player progresses, the attribute of the player is switched to the runner R.
When the batter B hits a hit, the batter B runs to the first base after hitting and stays on the base for a certain time because it is a hit.
In the measuring device control means 13, a time Tl longer than the time required for the player to go out and return to the bench is set as a condition value for determining the advance position.
When the batter B stays in the bag for a time longer than the time Tl, the measuring device control means 13 determines that the player having the batter attribute has stayed at the top for a certain time, and the hit result of this batter Is confirmed as a hit.
Moreover, the measuring device control means 13 measures the running time t01 between the home base and the first base of the player.

Now, the measuring device control means 13 that has confirmed the hit result as a hit transmits this information to the video extraction means 11c. As shown in FIG. 2A, the video extracting unit 11c sets the time at this time as the OUT time for setting the highlight scene.
Then, referring to the correspondence table shown in FIG. 2 (b), from the pitcher average time tp0 set in advance and the home base-one-spot running time t01 measured by the measuring device control means 13, the batting result Is set to tp0 + t01.
As shown in FIGS. 3A to 3E, the time from when the pitcher enters the pitching motion until the pitcher reaches the batter is set as the pitcher average pitch time tp0. When he / she goes out, the running time t01, t12, t23, t30 between each of the athletes is measured and used as the running time.
2B, the video time length is set to tp0 + t01 in the case of a hit, and the video time length is set to tp0 + t01 + t12 in the case of a double hit. When hitting, etc., the video time length is set based on the average pitch time and the running time between each base.

When the video time length is set as described above, the video extraction unit 11c sets an IN time that is retroactive from the OUT time by a determined video time length, as shown in FIG. Then, the video from the IN time to the OUT time is extracted as a highlight scene from the encoded video.
In the above description, the case of a hit has been described. For example, if a runner steals the runner, the player proceeds to the next kite and stays in the kite for a predetermined time or longer. Then, the OUT time is set from that time, and the IN time is set from the run time of the runner, and the highlight scene is extracted in the same manner as described above. Also, highlight scenes such as fine play may be extracted using information other than the above-described electronic tag information such as the size of cheering at a baseball field.

When the highlight scene is extracted, the video extraction unit 11c acquires the player information of the player from the player information storage unit 11a, highlights the player's hits and other play results, highlight scene, and player information from the distribution server 14. Registration is performed in the scene storage unit 14a via the communication control units 11d and 14d and the data registration processing unit 14b.
When a service user views a baseball highlight scene, a predetermined URL of the distribution server 14 is accessed from each individual viewing terminal 15 or the like.
For example, the distribution processing unit 14c sets an input screen as illustrated in FIG. When the general viewer selects a player name on the same screen, the distribution processing unit 14c of the distribution server 14 selects the highlight scene of the corresponding player from the highlight scene storage means 14a, and the screen as shown in FIG. Delivered to the viewing terminal 15 or the like. As a result, the service user can view the highlight scene of the designated player.
