## Background
CROSS-REFERENCE TO RELATED APPLICATION
The present application claims priority from Japanese Patent Application No. JP 2008-243073 filed in the Japanese Patent Office on Sep. 22, 2008, the entire content of which is incorporated herein by reference.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a display control apparatus, a display control method, and a program capable of processing a moving image of a sports game, such as a soccer game in which players chase a moving object to be propelled in the sports game (e.g., a ball) to score.
2. Description of the Related Art
A soccer game has become more and more popular in recent years. Accordingly, soccer games have been broadcasted on television.
Not only Japanese domestic soccer games but also foreign soccer games (e.g., league games in European countries and countries in South America, world cup games, preliminary rounds of European championship, and the championship game) have been broadcasted on television.
In addition, with technical advance of television display devices, such as liquid crystal monitors, and with an increase in the size of television display devices, video of soccer games including fast motions has been naturally displayed. For example, skillful dribbling and shooting scenes can be clearly and beautifully broadcasted and displayed on television display devices.
SUMMARY OF THE INVENTION
In general, out-of-door games, such as soccer games, are played on a large field. Accordingly, since it is necessary that a television camera capture the image of a wide area of the field or an area in the vicinity of a ball (the moving object to be propelled in the game), the television camera is placed at a relatively high position relative to the stadium.
Accordingly, while the game is being played, an image of a wide area of the field or a small area near the ball is displayed, and a panning, tilting, or zoom operation is performed when the image is captured, if necessary.
For example, a zoom-in operation is performed on a player who has just scored a goal or an area in which a player committed a foul. Such a zoom-in operation is widely performed, and the zoom-in operation satisfies viewers of a soccer TV broadcast.
However, in general, soccer TV broadcasts tend to show a large area of the field, and it is difficult for viewers to identify individual players.
In addition, viewers (users) who want to watch a specific player desire to zoom in the player by themselves and enjoy the game.
In order to identify individual players playing in the large field, the names of the players may be displayed in the vicinity of the heads of the players in a screen. However, with this method, the viewers may not enjoy the game.
In addition, a soccer game has a rule called offside. However, in many cases, it is difficult for the viewer to recognize the offside line. Furthermore, in some cases, it is difficult for the viewer to trace the motion and trajectory of a ball.
Still furthermore, during a 90-minute game period, onlookers are often wildly excited (e.g., at a goal scene). In such a case, it is difficult for the viewers to immediately watch the scene in a recorded video.
Accordingly, the present invention provides a display control apparatus, a display control method, and a program that allows a viewer to display desired information associated with a game on a screen during a game broadcast.
According to an embodiment of the present embodiment, a display control apparatus includes a receiving unit configured to receive a television broadcast signal containing at least remote broadcast image information, a display unit configured to display image information contained in the television broadcast signal, a recording and reproducing unit configured to record and reproduce the image information, a player information acquiring unit configured to acquire, from the remote broadcast image information, player information regarding players in a sports game included in a broadcast image signal, and a recording and reproducing control function unit configured to receive an audio signal contained in the television broadcast signal and generate an excitation graph representing a level of excitation of the broadcast sports game along a time line of the image. The recording and reproducing control function unit associates the generated excitation graph with the image of the sports game, time information, and the player information and records the generated excitation graph, the image of the sports game, the time information, and the player information in the recording and reproducing unit. Upon receiving information indicating a break in the sports game, the recording and reproducing control function unit instructs the display unit to display the excitation graph together with the image of the sports game recorded in the recording and reproducing unit.
The recording and reproducing control function unit can instruct the display unit to display the player information and the excitation graph together with the image of the sports game recorded in the recording and reproducing unit.
The recording and reproducing control function unit can instruct the display unit to display a live image together with the image of the sports game, the player information, and the excitation graph recorded in the recording and reproducing unit.
The recording and reproducing control function unit can instruct the display unit to display the excitation graph so that one of predetermined time periods along the time line of the graph is selectable.
The recording and reproducing control function unit can instruct the display unit to display the player information so that the player information regarding one of the players is selectable, and, upon receiving an instruction to select a time period for which the selected and displayed player appears in the broadcast image, the recording and reproducing control function unit can reproduce the recorded image corresponding to the selected time period and instruct the display unit to display the reproduced image.
According to another embodiment of the present invention, a display control method includes the steps of receiving a television broadcast signal containing at least remote broadcast image information, displaying image information contained in the television broadcast signal on a display unit, acquiring, from the remote broadcast image information, player information regarding players in a sports game included in a broadcast image signal, receiving an audio signal contained in the television broadcast signal and generating an excitation graph representing a level of excitation of the broadcast sports game along a time line of the image, associating the generated excitation graph with the image of the sports game, time information, and the player information and recording the generated excitation graph, the image of the sports game, the time information, and the player information in a recording and reproducing unit, and, upon receiving information indicating a break in the sports game, displaying, on the display unit, the excitation graph together with the image of the sports game recorded in the recording and reproducing unit.
According to still another embodiment of the present invention, a program includes program code for causing a computer to execute a display control process. The display control process includes the steps of receiving a television broadcast signal containing at least remote broadcast image information, displaying image information contained in the television broadcast signal on a display unit, acquiring, from the remote broadcast image information, player information regarding players in a sports game included in a broadcast image signal, receiving an audio signal contained in the television broadcast signal and generating an excitation graph representing a level of excitation of the broadcast sports game along a time line of the image, associating the generated excitation graph with the image of the sports game, time information, and the player information and recording the generated excitation graph, the image of the sports game, the time information, and the player information in a recording and reproducing unit, and, upon receiving information indicating a break in the sports game, displaying, on the display unit, the excitation graph together with the image of the sports game recorded in the recording and reproducing unit.
According to the present invention, for example, the receiving unit receives a television broadcast signal containing remote broadcast image information of a sports game, and the received remote broadcast image is displayed on the display unit.

Thereafter, the video decoding circuit 53 supplies the decoded signal PCTR to the superimposing circuit 54, the player information acquiring unit 55, the field information acquiring unit 56, and the position information acquiring unit 57.
By using the OSD control circuit 59, the superimposing circuit 54 superimposes, on the display device 20, various information (e.g., a cursor, the name of a player, the uniform number of the player, an offside line, or a ball trajectory image serving as additional information) over the signal PCTR output from the video decoding circuit 53. Thereafter, the superimposing circuit 54 displays the image.
The superimposing circuit 54 has a function of superimposing, using the OSD control circuit 59, the excitation graph over a playback video reproduced by the recording and reproducing unit 80 and displaying the image on the display device 20.
The player information acquiring unit 55 acquires the ball game information included in the broadcast video signal, such as player information IPLY regarding players (start players and reserve players) of the two soccer teams. Thereafter, the player information acquiring unit 55 stores the player information IPLY.
The player information IPLY acquired by the player information acquiring unit 55 includes the names of the players, the uniform numbers of the players, and photos of the faces of the players.
The player information acquiring unit 55 supplies the acquired and stored player information IPLY to the field information acquiring unit 56 and the OSD control circuit 59.
The field information acquiring unit 56 acquires field information IFLD from an unedited TV broadcast video of a soccer game using a correspondence between a line in an input image and a field model. Thereafter, the field information acquiring unit 56 stores the field information IFLD and, subsequently, supplies the acquired and stored field information IFLD to the field information acquiring unit 56 and the OSD control circuit 59.
The position information acquiring unit 57 acquires, from the video signal PCTR of the soccer TV broadcast, ball position information IBLP regarding a ball located inside or outside the field using the field information IFLD and position information IPLYP regarding each of the players on the basis of the field information IFLD and the player information IPLY. Thereafter, the position information acquiring unit 57 supplies the acquired ball position information IBLP and the player position information IPLYP to the OSD control circuit 59.
FIG. 3 is a block diagram illustrating an exemplary configuration of the position information acquiring unit 57 according to the present embodiment.
As shown in FIG. 3, the position information acquiring unit 57 includes a ball position information acquiring sub-unit 571 serving as a moving-object position information acquiring unit and a player position information acquiring sub-unit 572.
The ball position information acquiring sub-unit 571 acquires, from the video signal. PCTR of the soccer TV broadcast, the position information IBLP regarding the ball located inside or outside the field using the field information IFLD. Thereafter, the ball position information acquiring sub-unit 571 supplies the acquired position information IBLP to the OSD control circuit 59.
The player position information acquiring sub-unit 572 acquires, from the video signal PCTR of the soccer TV broadcast, the player information IPLYP regarding each of the players located inside or outside the field using the field information IFLD and the player information IPLY. Thereafter, the player position information acquiring sub-unit 572 supplies the acquired position information IPLYP to the OSD control circuit 59.
For example, in order to acquire the position information in the ball position information acquiring sub-unit 571 and the player position information acquiring sub-unit 572, a technology such as but not limited to the technology described in the following Non-Patent document can be applied:
The Institute of Electronics, Information and Communication Engineers Report, PRMU, Image Recognition and Media Understanding, Technical report of IEICE. PRMU, Vol. 103, No. 585 (20040116), pp. 95-100, PRMU2003-214, The Institute of Electronics, Information and Communication Engineers, ISSN: 09135685
In such a case, the position information acquiring unit 57 computes, from unedited TV broadcast image of a soccer game, a homography matrix using a correspondence between a line in the input video signal and a field model. The position information acquiring unit 57 then estimates the ball position and the player positions in the field.
Unlike video captured by a fixed camera, TV broadcast video includes moving images obtained through panning, tilting, and zoom operations. Accordingly, the homography matrix changes as time passes.
Therefore, in order to compute the homography matrix, the position information acquiring unit 57 compares the correspondences between lines in the video and the field model with each other in a space generated by parameters of Hough transform. Thus, the position information acquiring unit 57 computes a correspondence between the lines and estimates the homography matrix and, subsequently, estimates the ball position and the players' positions in the field.
For example, the ball position information and the player position information acquired by the position information acquiring unit 57 during the game play are recorded in the recording and reproducing unit 80 together with the time information and the excitation graph while the video is being recorded.
In response to an instruction signal received from the remote commander 60, the microcomputer 58 controls the control unit 50 functioning as a TV receiver. In response to an instruction signal received from the remote commander 60, the microcomputer 58 changes a channel or controls the volume.
In addition, the microcomputer 58 analyzes a signal input from the remote commander 60. In accordance with the analysis processing, the microcomputer 58 sends, to the OSD control circuit 59, an instruction to generate various information, such as a cursor, the name of a player, the uniform number of the player, the offside line, or the trajectory of the ball serving as additional information, and an instruction regarding OSD display.
In response to a command CMD of the microcomputer 58, the OSD control circuit 59 generates a variety of OSD video signals for displaying icons, characters, and figures in the display screen. The OSD control circuit 59 then outputs the OSD video signals to the superimposing circuit 54.
In addition, in response to a command CMD of the microcomputer 58, the OSD control circuit 59 generates various information, such as a cursor, the name of a player, the uniform number of the player, the offside line, the trajectory of the ball, an excitation graph, and a photo of the face of the player serving as additional information.
Subsequently, the OSD control circuit 59 outputs the generated OSD video signals to the superimposing circuit 54.
The video based on the OSD video signals is superimposed over the video based on the TV video signal output from the video decoding circuit 53 by the superimposing circuit 54. The video is then output to the display device 20.
In addition, the OSD control circuit 59 has a sub-display function of displaying, in response to the command CMD received from the microcomputer 58, the photos of the faces and the names of the players for each of the teams in a predetermined sub-area of the display area when, for example, TV broadcast video of a soccer game is displayed on the display device 20.
FIG. 4 is a functional block diagram of a main portion of the OSD control circuit 59 according to the present embodiment.
As shown in FIG. 4, the OSD control circuit 59 includes a sub-display control function unit 591, a cursor control function unit 592, an automatic tracking control function unit 593, a player information control function unit 594, an offside line control function unit 595, a ball trajectory control function unit 596, and a recording and reproducing control function unit 597.
The sub-display control function unit 591, the cursor control function unit 592, the automatic tracking control function unit 593, the player information control function unit 594, the offside line control function unit 595, the ball trajectory control function unit 596, and the recording and reproducing control function unit 597 are connected to a bus 598.
Note that the sub-display control function unit 591 functions as a player information providing unit. In addition, the offside line control function unit 595 and the ball trajectory control function unit 596 function as a line forming unit.
In addition, the sub-display control function unit 591 has a function of displaying, in response to the command CMD received from the microcomputer 58, the photos of the faces and the names of the players for each of the teams in a predetermined sub-area of the display area when, for example, TV broadcast video of a soccer game is displayed on the display device 20.
Note that the sub-display function is started in response to a sub-display command CMD submitted by the microcomputer 58 when a user selects a favorite mode using, for example, the remote commander 60.
FIG. 5 illustrates an example of a display screen of the display device including a sub-display area.
In the example of FIG. 5, a sub-display area 220 is formed and displayed in the lower section of a main display area 210 in a display area 21 of the display device 20.
A score display area 221 used for displaying the score of the game is provided in the middle of the sub-display area 220. Display areas 222 and 223 used for displaying the player information of the opposing teams are formed on either side of the score display area 221.
The sub-display control function unit 591 controls the display areas 222 and 223 so that the photos of the faces and the names (Romaji representation for Japanese players) of the players of the two teams are displayed in the display areas 222 and 223.
In addition, the sub-display control function unit 591 forms a face photo display area 224 for each of the players so that the face photo display area 224 is selectable. For example, the selected face photo display area 224 is highlighted.
Furthermore, when the sub-display control function unit 591 displays the name and uniform number of at least one of the players in the main display area 210, the sub-display control function unit 591 highlights the face photo display area 224 of the player.
As used herein, the term “highlight” refers to displaying an area with a luminance higher than that of the other areas.
For example, when a particular player is selected in the sub-display area and if the cursor control function unit 592 receives a cursor setting command CMD from the microcomputer 58, the cursor control function unit 592 displays a cursor so that the cursor surrounds a player in the field displayed in the main display area 210 using the player position information.
FIG. 6 illustrates a screen in which a cursor CSL is set on a selected player.
As shown in FIG. 6, when, for example, a particular player is selected in the sub-display area, the cursor control function unit 592 sets the cursor CSL on the player in the field displayed in the main display area 210 so that the cursor surrounds the player on the basis of the player position information.
After placing the cursor CSL on the selected player, if the cursor control function unit 592 receives a movement command CMD from the microcomputer 58, the cursor control function unit 592 moves the cursor CSL in a direction indicated by the movement command CMD. The direction corresponds to one of all directions determined by a user operation of a movement instruction switch of the remote commander 60.
After placing the cursor CSL on the selected player, if the cursor control function unit 592 receives a zoom-in command CMD from the microcomputer 58, the cursor control function unit 592 zooms in on the player indicated by the cursor CSL and the vicinity of the player by a zoom factor indicated by the zoom-in command. The zoom factor is determined by a user operation of a zoom switch of the remote commander 60.
FIG. 7 illustrates a first example of a zoom-in operation performed on a player selected using the cursor CSL. FIG. 8 illustrates a second example of a zoom-in operation performed on a player selected using the cursor CSL.
As shown in FIGS. 7 and 8, after placing the cursor CSL on the selected player, if the cursor control function unit 592 receives the zoom-in command CMD, the cursor control function unit 592 zoom in the player selected using the cursor CSL in the screen.
In the first example shown in FIG. 7, a displayed image in the main display area 210 is enlarged. In contrast, in the second example shown in FIG. 8, the size of a displayed image in the main display area 210 remains the same. However, a sub-display area 230 is formed on the right side of the drawing, and a zoom-in image of an area selected by the cursor CSL is displayed in the sub-display area 230.
The cursor control function unit 592 has a function of changing the zoom-in display image to the normal display image when the cursor control function unit 592 receives a zoom-in cancel command.
The cursor control function unit 592 further has a function of, upon receiving a cursor setting command for a ball from the microcomputer 58, setting the cursor CSL on the ball so that the cursor surrounds the ball.
FIG. 9 illustrates a screen in which the cursor CSL is set on a ball.
As shown in FIG. 9, upon receiving a cursor setting command CMD for a ball BL from the microcomputer 58, the cursor control function unit 592 sets the cursor CSL on the ball BL so that the cursor surrounds the ball BL.
Once the cursor CSL is set on a player PLY or the ball BL, the cursor control function unit 592 automatically tracks, using a tracking function of the automatic tracking control function unit 593, the player PLY or the ball while placing the cursor CSL on the player PLY or the ball BL.
For example, as shown in FIG. 9, once the cursor control function unit 592 places the cursor CSL on the player PLY or the ball BL, the automatic tracking control function unit 593 causes the cursor CSL to track the selected player PLY or ball BL. According to this tracking function, it is not necessary that the user's eyes seriously chase the player PLY or the ball BL and, therefore, the user can view a desired game scene in a relaxed state.
Upon receiving a player information display command CMD, the player information control function unit 594 displays, in the vicinity of the heads of players located within a predetermined area at the center of which is the ball BL, the names and uniform numbers of the players on the basis of the position information IBLP, the player position information IPLYP, and the player information IPLY.
If the player information control function unit 594 has received a command CMD containing a selected team name (Team A or Team B), the player information control function unit 594 displays the names and uniform numbers of the players in the vicinity of the heads of the players of the selected Team A or Team B located within the predetermined area, at the center of which is the ball BL.
The reason why the player information control function unit 594 displays the names and uniform numbers of only the players located within a predetermined area, at the center of which is the ball BL, is as follows.
During game play, the user may want to know which player is at which location. If the names and uniform numbers are displayed in the vicinity of the heads of all of the players, the screen becomes messy and, therefore, it is difficult for the user to easily view the screen. Accordingly, the names and uniform numbers of only players who possibly receive the ball are displayed.
FIG. 10 is a diagram illustrating an example in which the names and uniform numbers of only players located in the vicinity of the ball are displayed.
If the player information control function unit 594 has received a command CMD containing a selected team name (Team A or Team B), the user manually selects one of Team A and Team B. Thereafter, as shown in FIG. 10, the player information control function unit 594 displays the uniform numbers and names of the players in the vicinity of the heads of the players of the selected team located in the vicinity of the ball.
In the example shown in FIG. 10, the uniform numbers and names of players 10, 11, and 3 of Team A located in the vicinity of the ball are displayed.
In addition, the photo of the faces of the players having the displayed uniform numbers and names are highlighted in the face photo display area 224 of the sub-display area 220.
Upon receiving an offside line display command CMD, the offside line control function unit 595 displays the offside line in the main display area 210 on the basis of the field information IFLD, the ball position information IBLP, the player position information IPLYP, and the player information IPLY.
Upon receiving a ball trajectory display command CMD, the ball trajectory control function unit 596 displays a ball trajectory in the main display area 210 on the basis of the field information IFLD, the ball position information IBLP, the player position information IPLYP, and the player information IPLY.
Note that the offside line and the ball trajectory can be displayed on the screen at the same time or can be selectively and separately displayed.
FIG. 11 is a diagram illustrating a first example in which an offside line and a ball trajectory are displayed. FIG. 12 is a diagram illustrating a second example in which an offside line and a ball trajectory are displayed.
In FIGS. 11 and 12, an offside line LOFSD and a ball trajectory LTRBL are displayed in the same screen at the same time. In FIG. 11, for example, players on Team A are moving towards the goal of Team B (on offense), and only one offside line LOFSD is displayed. FIG. 12 illustrates a scene in which Team A and Team B are playing offence and defense in the midfield. Accordingly, in FIG. 12, two offside lines LOFSD are displayed.
As can be seen from FIGS. 11 and 12, the offside line LOFSD is not a thin line (a simple line), such as a field line. The offside line LOFSD has a width W that is substantially the same as the length of the stride of a player. For example, the offside line LOFSD is displayed with a semi-transparent color.
Unlike video captured by a fixed camera, TV broadcast video includes moving images obtained through panning, tilting, and zoom operations. Accordingly, if the offside line LOFSD is formed with a thin line, such as a field line, it may be difficult for the viewers to recognize the offside line LOFSD. Thus, according to the present embodiment, the offside line LOFSD has a certain width. In this way, the viewers can easily recognize the offside line LOFSD at any viewing angle and watch the soccer game with a high realistic sensation.
The recording and reproducing control function unit 597 receives the audio signal AUD from the audio decoding circuit 52 and generates an excitation graph that represents the level of excitation of onlookers along a time line of the video using the audio level of cheers.
The recording and reproducing control function unit 597 associates the generated excitation graph with time information, the player information IPLY, the player position information IPLYP, and the field information IFLD and records the excitation graph in the recording and reproducing unit 80 together with the video of the game.
The recording and reproducing control function unit 597 further has a function of, upon receiving information indicating game broadcast interruption, such as a halftime break, from the microcomputer 58, displaying the game video recorded in the recording and reproducing unit 80 together with a live image, the player information, and the excitation graph.
FIG. 13 illustrates an exemplary excitation video screen generated by the recording and reproducing unit 80 and displayed on the display device 20.
In order to display the excitation video screen, the recording and reproducing control function unit 597 forms, in the display area 21 of the display device 20, a video playback sub-area 240, a live image sub-area 250, a player information display sub-area 260, and an excitation graph display sub-area 270.
The excitation video screen can be displayed by displaying various video and information in the video playback sub-area 240, the live image sub-area 250, the player information display sub-area 260, and the excitation graph display sub-area 270 formed in the display area 21 of the display device 20.
The video playback sub-area 240 accounts for about 60 to 80 percent of the display area 21. The game video recorded in the recording and reproducing unit 80 is played back in the video playback sub-area 240.
For example, as shown in FIG. 13, the recording and reproducing control function unit 597 lays out the live image sub-area 250, the player information display sub-area 260, and the excitation graph display sub-area 270 on top of each other on the right side of the display area 21 so that each of the live image sub-area 250, the player information display sub-area 260, and the excitation graph display sub-area 270 is parallel to the video playback sub-area 240.
In the example shown in FIG. 13, the live image sub-area 250, the player information display sub-area 260, and the excitation graph display sub-area 270 are sequentially formed from the top to the bottom of the display area 21.
When the ongoing game broadcast is changed to a commercial (CM) video during, for example, a halftime break, the ongoing game broadcast is displayed in the live image sub-area 250. In this way, the viewers can watch the recorded video together with the live image.
The recording and reproducing control function unit 597 forms a display sub-sub area 261 for each player in the player information display sub-area 260. For example, a photo of the face of one of the players of the teams and the name of the player (Romaji representation for a Japanese player) are displayed in the display sub-sub area 261.
In the display sub-sub area 261, the photo of the face of the selected player is displayed with lighter highlighting. The team name is displayed to the left of the photo. The name and the uniform number of the player are displayed to the right of the photo.
A selected player whose information is displayed in the player information display sub-area 260 can be changed by the viewer (the user) by operating, for example, an up-down key of the remote commander 60.
The recording and reproducing control function unit 597 reads, from the recording and reproducing unit 80, an excitation graph 271 that represents the level of the excitation along the time line of the current broadcast game by using, for example, the level of cheers. Thereafter, the recording and reproducing control function unit 597 displays the excitation graph 271 in the excitation graph display sub-area 270.
The viewer can select one of predetermined periods in the time line of the excitation graph 271 by operating, for example, a left-right key of the remote commander 60. The excitation graph 271 in the selected period is highlighted with a frame.
In addition, the excitation graph 271 is displayed so as to represent the excitation level of the game in a spectrum fashion. Furthermore, for a period for which a player selected and displayed in the player information display sub-area 260 is being displayed in the game video, the excitation graph 271 is displayed with a highlight as indicated by a reference symbol “HLT”.
The recording and reproducing control function unit 597 basically performs control so as to display, in the video playback sub-area 240, the recorded video corresponding to the period selected using frame highlighting in the excitation graph 271 displayed in the excitation graph display sub-area 270.
Accordingly, the user can select any player displayed in the player information display sub-area 260. Thereafter, the user can use a cursor and select a highlighted and high-excitation period of the excitation graph 271 displayed in the excitation graph display sub-area 270.
With such an operation, the user can immediately display, in the video playback sub-area 240, video corresponding to a period for which a desired player appears and the onlookers of the game are excited.
The present embodiment has been described with reference to the case in which recorded video corresponding to the period selected using a highlight frame in the excitation graph 271 displayed in the excitation graph display sub-area 270 is played back in the video playback sub-area 240. However, a method for playing back video in the video playback sub-area 240 is not limited thereto. For example, video in which a player selected in the player information display sub-area 260 appears may be displayed in the video playback sub-area 240 if desired.
As described above, according to the present embodiment, by using the control function of the recording and reproducing control function unit 597, periods in which a selected player appears is indicated by highlight frames in the spectrum along the time line. By selecting one of the periods having a high excitation level using the cursor, playback of the corresponding video can be immediately started.
The remote commander 60 has a function of wirelessly transmitting, to the microcomputer 58 of the control unit 50, a channel selection command and a variety of display control commands regarding a game using, for example, infrared light.
When the user operates the remote commander 60, an infrared light command that instructs one of a variety of operations performed by the control unit 50 serving as a TV receiver is input to the light receiving unit 70. Thereafter, the command is converted into an electrical signal and is input to the microcomputer 58.
When a command signal received from the remote commander 60 is a signal instructing selection of a particular channel, the microcomputer 58 outputs a channel selection command corresponding to the signal to the TV tuner 51.
When a command signal received from the remote commander 60 is a signal instructing display control regarding a game, the microcomputer 58 outputs a command CMD corresponding to the signal to the OSD control circuit 59.
FIGS. 14A to 14D illustrate an exemplary configuration of the remote commander 60 according to the present embodiment. FIG. 14A is a front view of the remote commander 60. FIGS. 14B and 14C are side views of the remote commander 60. FIG. 14D is a back view of the remote commander 60.
The remote commander 60 includes a power switch 61, a channel up-down switch 62, and a volume up-down switch 63.
The power switch 61 is disposed on one of the side surfaces. The power switch 61 is operated in order to power on or off the TV receiver.
The channel up-down switch 62 is operated in order to change the current TV channel to the previous TV channel or the next TV channel.
The volume up-down switch 63 is operated in order to increase or decrease the output audio level.
Note that the remote commander 60 includes number keys thereon. However, the number keys are not shown in FIGS. 14A to 14D. For example, the number keys are used to select a TV channel corresponding to the number.

The four-way stick switch unit 64 includes a peripheral ring portion 641 and a push button 642 disposed at the center of the four-way stick switch unit 64. The ring portion 641 includes four buttons that allow a four-way stick to provide four functions. For example, the lower right button can serve as a zoom function button. The four switches also function as UP, DOWN, LEFT, and RIGHT keys for moving the cursor CSL upwards, downwards, leftwards, and rightwards, respectively. Furthermore, the zoom level can be determined in accordance with an amount of pushing of the push button 642.
The first function ON/OFF switch 65 is operated in order to turn on or off the player information display function.
The second function ON/OFF switch 66 is operated in order to turn on or off the offside line display function and the ball trajectory display function.
The third function ON/OFF switch 67 is operated in order to turn on or off the live image display function, the player information display function, the excitation graph display function, and the recorded video display function.
The team changeover switch 68 is disposed on the back side of the remote commander 60 in the upper section. For example, the team changeover switch 68 is operated in order to select one of Team A and Team B which are opponents of a soccer game.
The recording and reproducing unit 80 associates the received video with the excitation graph, the time information, the player information IPLY, the player position information IPLYP, and the field information IFLD and records the video. In addition, the recording and reproducing unit 80 displays the live image and reproduces the player information IPLY and the excitation graph as well as playing back the recorded game video.
An exemplary operation performed by the display control apparatus 10 according to the present embodiment is described with reference to a flowchart shown in FIG. 15.
After a user operates the power switch 61 of the power switch 61 so as to power on the display control apparatus 10 (step ST1), the user operates the number keys or the channel up-down switch 62 so as to instruct the display control apparatus 10 to select a predetermined TV channel (step ST2).
In this way, a command signal output from the remote commander 60 is input to the microcomputer 58 via the light receiving unit 70 of the control unit 50.
Upon receiving the command signal, the microcomputer 58 outputs, to the TV tuner 51, a TV channel selection command for selecting a TV channel that broadcasts, for example, a soccer TV game. Upon receiving the TV channel selection command, the TV tuner 51 selects a predetermined TV channel. Subsequently, the TV tuner 51 outputs the audio signal to the audio decoding circuit 52 and the video signal to the video decoding circuit 53.
The video signal is decoded by the video decoding circuit 53 and is sent to the display device 20 via the superimposing circuit 54. Thus, an image based on the decoded video signal is displayed on the display device 20. In addition, the audio decoding circuit 52 decodes the audio signal and outputs the decoded audio signal to the speaker 30.
In this way, the soccer TV broadcast is displayed on the display device 20 (step ST3), and the TV audio signal is output from the speaker 30.
In addition, the video signal PCTR decoded by the video decoding circuit 53 is supplied to the player information acquiring unit 55, the field information acquiring unit 56, and the position information acquiring unit 57.
The player information acquiring unit 55 acquires the ball game information included in the broadcast video signal, such as the player information IPLY regarding players (start players and reserve players) of the two soccer teams. Thereafter, the player information acquiring unit 55 stores the player information IPLY in a storage unit (not shown) (step ST4).
The acquired and stored player information IPLY is supplied to the field information acquiring unit 56 and the OSD control circuit 59.
The field information acquiring unit 56 acquires the field information IFLD from an unedited TV broadcast video of a soccer game using a correspondence between a line in an input image and a field model. Thereafter, the field information acquiring unit 56 stores the field information IFLD (step ST5). Subsequently, the field information acquiring unit 56 supplies the acquired and stored field information IFLD to the field information acquiring unit 56 and the OSD control circuit 59.
The position information acquiring unit 57 acquires, from the video signal PCTR of the soccer TV broadcast, the position information IBLP regarding a ball located inside or outside the field using the field information IFLD and the position information IPLYP regarding each of the players on the basis of the field information IFLD and the player information IPLY (steps ST6 and ST7). Thereafter, the position information acquiring unit 57 supplies the acquired ball position information IBLP and the player position information IPLYP to the OSD control circuit 59.
In addition, the recording and reproducing control function unit 597 of the OSD control circuit 59 receives the audio signal AUD from the audio decoding circuit 52, the player information IPLY, the player position information IPLYP, the field information IFLD, and the ball position information IBLP. The recording and reproducing control function unit 597 generates an excitation graph that represents the level of excitation of onlookers along a time line of the video using the audio level of cheers (step ST8). Thereafter, the recording and reproducing control function unit 597 associates the generated excitation graph with time information, the player information IPLY, the player position information IPLYP, and the field information IFLD and records the excitation graph in the recording and reproducing unit 80 together with the video of the game (step ST9).
At that time, if a user who watches the soccer TV broadcast selects a favorite mode and submits a command to display player information using the remote commander 60, processing shown in FIG. 16 is performed.
Upon receiving the command, the microcomputer 58 submits a sub-display command CMD to the sub-display control function unit 591 of the OSD control circuit 59. The sub-display control function unit 591 displays a predetermined sub-area of the display area including the photos of the faces and the names of the players for each of the teams via the superimposing circuit 54 (step ST10). In such a case, for example, as shown in FIG. 5, the sub-display area 220 is formed and displayed in the lower section of a main display area 210 in a display area 21 of the display device 20. For example, the photos of the faces and the names (Romaji representation for Japanese players) of the players of each of the two teams are displayed.
When the user selects the face photo display area 224 in which a favorite player displayed in the sub-display area 220 is to be displayed using the UP, DOWN, LEFT, and RIGHT keys (step ST11), the face photo display area 224 of the favorite player is highlighted, for example.
Thereafter, for example, a particular player is selected in the sub-display area, and the OSD control circuit receives a cursor setting command CMD from the microcomputer 58.
Thus, the cursor control function unit 592 of the OSD control circuit 59 displays the cursor CSL so that the cursor CSL surrounds the player in the field displayed in the main display area 210 (step ST12).
At that time, if the user instructs to move the cursor CSL using the UP, DOWN, LEFT, and RIGHT keys of the remote commander 60, a movement command CMD is input from the microcomputer 58 to the OSD control circuit 59 (step ST13).
Upon receiving the movement command CMD from the microcomputer 58, the cursor control function unit 592 moves, using the superimposing circuit 54, the cursor CSL in a direction indicated by the movement command CMD (step ST14). The direction corresponds to one of all directions determined by a user operation of a movement instruction switch of the remote commander 60.
In addition, if the user performs a predetermined key operation on the four-way stick switch unit 64 of the remote commander 60 and instructs a zoom operation and the zoom level using the push button 642, a zoom-in command CMD is input from the microcomputer 58 to the OSD control circuit 59 (ST15).
In this way, the cursor control function unit 592 receives the zoom-in command from the microcomputer 58, and the cursor control function unit 592 zooms in the player indicated by the cursor CSL by a zoom factor indicated by the zoom-in command using the superimposing circuit 54 (step ST16).
In this case, as shown in FIG. 7, the image displayed in the main display area 210 is magnified.
Alternatively, as shown in FIG. 8, the size of a displayed image in the main display area 210 remains the same. However, the sub-display area 230 is formed on the right side of the drawing, and a zoom-in image of an area selected by the cursor CSL is displayed in the sub-display area 230.
At that time, if the user submits a zoom-in cancel instruction using the remote commander 60, a zoom-in cancel command CMD is input from the microcomputer 58 to the OSD control circuit 59 (step ST17).
Upon receiving the zoom-in cancel command CMD from the microcomputer 58, the cursor control function unit 592 changes the zoom-in display image to the normal display image (step ST18).
In addition, as in the case of the cursor setting on a player, when the user submits a cursor setting instruction for the ball BL, the processing as shown in FIG. 17 is performed.
When the cursor setting instruction is submitted, the OSD control circuit 59 receives a cursor setting command CMD for a ball BL from the microcomputer 58. Upon receiving the cursor setting command CMD, the cursor control function unit 592 of the OSD control circuit 59 places the cursor CSL on the ball BL displayed in the field in the main display area 210 so that the cursor CSL surrounds the ball BL (steps ST20 and ST21).
At that time, if the user instructs to move the cursor CSL using the UP, DOWN, LEFT, and RIGHT keys of the remote commander 60, a movement command CMD is input from the microcomputer 58 to the OSD control circuit 59 (step ST22).
Upon receiving the movement command CMD from the microcomputer 58, the cursor control function unit 592 moves, using the superimposing circuit 54, the cursor CSL in a direction indicated by the movement command CMD (step ST23). The direction corresponds to one of all directions determined by a user operation of a movement instruction switch of the remote commander 60.
In addition, if the user performs a predetermined key operation on the four-way stick switch unit 64 of the remote commander 60 and instructs a zoom operation and the zoom level using the push button 642, a zoom-in command CMD is input from the microcomputer 58 to the OSD control circuit 59 (ST24).
In this way, the cursor control function unit 592 receives the zoom-in command from the microcomputer 58, and the cursor control function unit 592 zooms in the ball BL indicated by the cursor CSL by a zoom factor indicated by the zoom-in command using the superimposing circuit 54 (step ST25).
In this case, as shown in FIG. 9, the image displayed in the main display area 210 is magnified.
At that time, if the user submits a zoom-in cancel instruction using the remote commander 60, a zoom-in cancel command CMD is input from the microcomputer 58 to the OSD control circuit 59 (step ST26).
Upon receiving the zoom-in cancel command CMD from the microcomputer 58, the cursor control function unit 592 changes the zoom-in display image to the normal display image (step ST27).
When, as illustrated by the flowchart in FIG. 16 or 17, a cursor is placed on a player or a ball, the automatic tracking process is started, as illustrated by the flowchart in FIG. 18.
If a player PLY or a ball BL is selected for the cursor control function unit 592 by using the cursor CSL (step ST30), the player PLY or the ball BL is automatically tracked using the tracking function of the automatic tracking control function unit 593 (step ST31). At that time, the automatic tracking control function unit 593 moves the cursor CSL so that the cursor CSL automatically follows the player PLY or the ball BL.
When the user submits an automatic tracking cancel instruction using the remote commander 60, an automatic tracking cancel command CMD is input from the microcomputer 58 to the OSD control circuit 59 (step ST32). Upon receiving the automatic tracking cancel command CMD from the microcomputer 58, the cursor control function unit 592 changes the display image to the normal display image (step ST33).
In addition, when the user submits a player information display instruction using the first function ON/OFF switch 65 of the remote commander 60, the processing as shown in FIG. 19 is performed.
When the player information display instruction is submitted, a player information display command CMD is input from the microcomputer 58 to the OSD control circuit 59. Upon receiving the player information display command CMD (step ST40), the player information control function unit 594 of the OSD control circuit 59 selects players located within a predetermined area, at the center of which is the ball BL, on the basis of the ball position information IBLP, the player position information IPLYP, and the player information IPLY (step ST41). Thereafter, if the player information control function unit 594 has received a command CMD containing a selected team name (Team A or Team B), the player information control function unit 594 displays the names and uniform numbers of the players in the vicinity of the heads of the players of the selected Team A or Team B located within the predetermined area, at the center of which is the ball BL (step ST42).
If the player information control function unit 594 has received a command CMD containing a selected team name (Team A or Team B), the user manually selects one of Team A and Team B. Thereafter, as shown in FIG. 10, the player information control function unit 594 displays the uniform numbers and names of the players in the vicinity of the heads of the players of the selected team located in the vicinity of the ball.
In the example shown in FIG. 10, the uniform numbers and names of players 10, 11, and 3 of Team A located in the vicinity of the ball are displayed.
In addition, the photo of the faces of the players having the displayed uniform numbers and names are highlighted in the face photo display area 224 of the sub-display area 220.
In addition, when the user who is watching a TV broadcast of a soccer game submits an offside-line and ball-trajectory display instruction using the second function ON/OFF switch 66 of the remote commander 60, the processing as shown in FIG. 20 is performed.
When the offside-line and ball-trajectory display instruction is submitted, the OSD control circuit 59 receives an offside-line and ball-trajectory display command CMD from the microcomputer 58 (step ST50).
The offside line control function unit 595 of the OSD control circuit 59 receives an offside-line display command CMD, while the ball trajectory control function unit 596 of the OSD control circuit 59 receives a ball-trajectory display command CMD.
Upon receiving the offside-line display command CMD, the offside line control function unit 595 displays the offside line in the main display area 210 using the superimposing circuit 54 on the basis of the field information IFLD, the ball position information IBLP, the player position information IPLYP, and the player information IPLY (step ST51).
Note that, unlike a field line which is a thin line, the offside line LOFSD is displayed so as to have a width that is substantially the same as the length of the stride of a player, for example.
In addition, upon receiving a ball trajectory display command CMD, the ball trajectory control function unit 596 displays a ball trajectory in the main display area 210 on the basis of the field information IFLD, the ball position information IBLP, the player position information IPLYP, and the player information IPLY (step ST52).
For example, as shown in FIGS. 11 and 12, the offside line LOFSD and the ball trajectory LTRBL are displayed in the same screen at the same time. In FIG. 11, for example, players on Team A are moving towards the goal of Team B (on offense), and only one offside lines LOFSD is displayed. FIG. 12 illustrates a scene in which Teams A and B are playing offence and defense in the midfield. Accordingly, in FIG. 12, two offside lines LOFSD are displayed.
When the OSD control circuit 59 receives information indicating a break in the soccer TV broadcast (e.g., a halftime break) from the microcomputer 58, the processing as shown in FIG. 21 is performed.
Subsequently, as shown in FIG. 21, when the user who is watching TV broadcast of a soccer game operates the third function ON/OFF switch 67 of the remote commander 60 (step ST60), the processing shown in steps ST61 to ST67 is performed.
At that time, as shown in FIG. 13, the recording and reproducing control function unit 597 forms, in the display area 21 of the display device 20, the video playback sub-area 240, the live image sub-area 250, the player information display sub-area 260, and the excitation graph display sub-area 270.
Thereafter, the recording and reproducing control function unit 597 displays the live image, the player information, and the excitation graph together with the video of the game recorded in the recording and reproducing unit 80 (steps ST61 to ST64).
When the ongoing game broadcast is changed to a commercial (CM) video during, for example, a halftime break, the current broad cast video is displayed in the live image sub-area 250.
The recording and reproducing control function unit 597 forms a display sub-sub area 261 for each player in the player information display sub-area 260. For example, a photo of the face of one of the players of the teams and the name of the player (Romaji representation for a Japanese player) are displayed in the display sub-sub area 261.
In the display sub-sub area 261, the photo of the face of the selected player is displayed with lighter highlighting. The team name is displayed to the left of the photo. The name and the uniform number of the player are displayed to the right of the photo.
The recording and reproducing control function unit 597 reads, from the recording and reproducing unit 80, an excitation graph 271 that represents the level of the excitation along the time line of the current broadcast game by using, for example, the level of cheers. Thereafter, the recording and reproducing control function unit 597 displays the excitation graph 271 in the excitation graph display sub-area 270.
In addition, for a period for which a player selected and displayed in the player information display sub-area 260 is being displayed in the TV broadcast video, the excitation graph 271 is displayed with a highlight as indicated by a reference symbol “HLT”.
At that time, the user selects a desired player to be displayed in the playback video using the UP/DOWN keys of the remote commander 60 (step ST65). Thereafter, the user operates the RIGHT/LEFT keys of the remote commander 60 and selects a highlighted and high-excitation period of the excitation graph 271 for which the selected player appears (step ST66).
Upon receiving the selection command, the recording and reproducing control function unit 597 displays the recorded video corresponding to the selected period in the video playback sub-area 240 (step ST67). Note that the selected period is highlighted with a frame in the excitation graph 271 displayed in the excitation graph display sub-area 270 and, during the period, the selected player appears in the video.
With such an operation, the user can immediately display, in the video playback sub-area 240, video corresponding to a period for which a desired player appears and the onlookers of the game are excited.
