However, in the present invention, even in the case of recording, it is possible to participate in the quiz (can receive the TV synchronization service), so that the correct answer can be slowly seen at the viewer's pace, and the customer satisfaction of the viewer can be improved. . In addition, in that case, depending on the viewer, since the CM program is watched a plurality of times, the effect of the CM program as a CM can be improved. In addition, by updating the contents of the TV synchronization service, even if you answer the quiz once, you will want to watch the CM program again, so it is possible to further improve the CM effect of the CM program It becomes. In addition, about the update of the content of TV synchronous service, it is also possible to notify by other TV program, the said CM program, a magazine, or radio. In this case, only the service control data of the service server 2 is updated, and it is not necessary to update the CM program itself. Therefore, the effect of the CM program can be improved at low cost.

FIG. 5 is a diagram for explaining an outline of a method for setting coordinates (positions) of coordinates on a screen and correct answers of quizzes. FIG. 5A is the same as FIG. 4C and shows a state in which the video 202 is displayed on the screen 200. This video 202 is composed of normal video data 202a and message data 202b as image data for synthesis. In FIG. 5B, the screen mask 221 shown in FIG. 5C is further synthesized. However, the screen mask 221 is not actually displayed on the screen 200. In the video 202, dummy points 204-1 to 204-n and correct points 205 that can be clicked (selected) with a pointing device are set. They are set by the coordinates of the dummy position 117, the position mask designation 118, the position mask designation 122, and the screen mask 221.
In the example of this figure, it is as follows.
(A) Dummy point 204-1:
Dummy position 117-1 of service control data 100: (h6, v1)
Position mask specification 118-1 of service control data 100: Screen mask 221
(B) Dummy point 204-2:
Dummy position 117-2 of service control data 100: (h2, v3)
Position mask specification 118-2 of service control data 100: Screen mask 221
(C) Correct answer point 205
Correct answer designation position 121 of service control data 100: (h4, v2)
Position mask specification 118-2 of service control data 100: Screen mask 221
In the example of this figure, the position display flag 125 is turned off, and the markers indicating the dummy points 204-1 to 204-2 and the correct point 205 are not displayed.

  Thus, in the present invention, an image mask is designated, and the position of each point is designated using the coordinates in the image mask. Here, the image mask can correspond to any screen size by changing in a similar manner corresponding to the size of the screen 200 of the display device 28.

  Further, the screen mask is not limited to the screen mask 221, but for example, the screen mask 222 in which coordinates can be set more finely than the screen mask 221 as shown in FIG. A screen mask (SMP3) 223 whose coordinates are different depending on the location as shown in (e) can be used. Since the screen mask 221 is relatively coarsely divided, it is suitable for a simple quiz and is suitable for the recording / playback apparatus 1 for TV. Since the screen mask 222 is relatively finely divided, it is suitable for a quiz to be solved over time, and is suitable for the recording / playback apparatus 1 for PC. The screen mask 223 has a coarsely divided area and a finely divided area, and is intermediate between the screen mask 221 and the screen mask 222.

  FIG. 6 is a schematic diagram illustrating the advantage of using an image mask. FIG. 6A shows the case where the image mask of the present invention is used, and FIG. 6B shows the case where the conventional screen coordinates are used. Referring to FIG. 6A, in the present invention, in order to specify the point 231 of the video 202, it is only necessary to specify the image cell 221 and its coordinates (h7, v3). If the image mask is standardized, its expression can be simplified, and the amount of data combining the image mask and coordinates can be reduced. On the other hand, referring to FIG. 6B, if absolute coordinates are used to specify the point 231 of the video 202, at least two points P1 (x1, y1) and P2 (x2, y2) are necessary. Depending on the situation, 4 points may be required. This increases the amount of coordinate data. In addition, in order to transmit the point 231 as information related to the CM program by a general medium such as a magazine, a newspaper, or oral media, the expression method using the image coordinates and coordinates is the expression method using absolute coordinates. In comparison, it is preferable because it is easy to understand and can easily communicate.

  Furthermore, if this method is used, the position on the image can be designated only by general-purpose instructions (eg, identification information and coordinates for designating an image mask) regardless of the physical screen configuration and shape. Thereby, it is effective as a standard interface for realizing various services provided by using the position on the image.

  FIG. 7 is a schematic diagram showing an image when the quiz is answered correctly. FIG. 7A shows a case where the viewer clicks the correct point 205 (FIG. 5) of the video 202 with the pointer 240 of the pointing device. Here, the viewer clicks the lotion bottle 241 placed on the table 242 with reference to the hint “bottle” of the hint message 112 described in the message data 202b. FIG. 7B shows a change on the video 202 that occurs as a result of clicking the correct answer point. Based on the data (scores, messages, and symbols) of the score 123 of the service control data 100, message data 243 and a symbol 245 are generated and displayed. That is, in the video 202, a symbol 245 visually indicating the correct answer and a message 243 indicating the score 123 acquired by the correct answer and the total points (obtained from the service server 2 via the network 4; described later) are displayed. .

  FIG. 8 is a schematic diagram illustrating another image mask and advantages of using it. FIG. 8A shows the case where the image mask of the present invention is used, and FIG. 8B shows the case where the conventional screen coordinates are used. Referring to FIG. 8A, in the present invention, in order to specify the point 272 on the screen 200, it is only necessary to specify the image mask 226 and its coordinates (P2, R4). If the image mask is standardized, its expression can be simplified, and the amount of data combining the image mask and coordinates can be reduced. On the other hand, referring to FIG. 8B, when absolute coordinates are used to designate a point 272a that is substantially the same as the point 272 on the screen 200, P3 (x3, y3), P4 (x4, y4),. At least 10 points (x12, y12) are necessary, and the amount of coordinate data increases. In addition, in order to transmit the point 272 as information related to the CM program by general media such as magazines, newspapers, and oral media, the expression method using the image coordinates and coordinates is the expression method using absolute coordinates. In comparison, it is preferable because it is easy to understand and can easily communicate. The image mask having such a shape is preferably applied to a game such as a dart, a circular shape or a concentric circular shape that exists in the natural world such as a typhoon, a plant stem, a nebula, or the earth.

  FIG. 9 is a schematic diagram illustrating the advantage of using another image mask. This figure shows a case where the image mask 227 having an oblique grid shape according to the present invention is used. In this case, the same effect as in the case of FIG. 8 can be obtained as compared with the case of using the coordinates of the conventional screen. The image mask having such a shape is preferably applied to an object or a position that is tilted in the natural world and an artificial structure.

  The above screen masks are merely examples, and the present invention is not limited to these examples. That is, various screen masks can be set by arranging grids so as to correspond to various geometric shapes. Here, to arrange the grid so as to correspond to the geometric shape is to set the grid so that the position in the geometric shape can be expressed only with simple coordinates. And the various image masks 221, 222, 223, 226, and 227 described above, such as arranging a grid with radial lines extending from the center.

  FIG. 10 is a diagram illustrating an outline of a method for displaying the correct coordinates (positions) of the quiz on the screen. In the case of FIG. 5C, the markers indicating the dummy points 204-1 and 204-2 and the correct answer point 205 are not clearly shown on the screen 200. However, as shown in this figure, it may be clearly shown as markers (indicated by double circles) indicating dummy points 234-1 and 234-2 and correct answer points 235. In this case, for example, every time the “→” button of the remote controller is pressed, dummy point 234-1 (double circle marker) → correction point 235 (double circle marker) → dummy point 234-2 (double circle marker) Alternatively, the pointer of the pointing device may be moved and selected with the enter button.

  As a case where a marker display indicating each point is used, it is used, for example, when it is desired to make a quiz easy, or when it is difficult for a viewer to determine a position. For example, when the display of the marker indicating each point is not used, the viewer clicks on the screen with a pointing device in a trial and error manner according to the hint message and searches for the correct point. This is used when you want to give hints by word of mouth.

  FIG. 11 is a diagram for explaining a video size changing method. In the case where the display device 28 is a PC monitor or a large digital TV, in addition to the case where the display device 28 is displayed in full screen, such as the screen 200 displayed on the right side in the figure, the screen in the full screen screen 200a displayed on the left side in the figure. It may be partially displayed as in 200b. When a part of the screen 200a is displayed as in the screen 200b, coordinate conversion (address conversion) is performed. The coordinate conversion method can be easily performed by similarity conversion by acquiring the position and size of the TV display window (screen 200b) in the screen 200a.

  In addition, image conversion between a high-definition image having an aspect ratio of 16: 9 and an ordinary image having an aspect ratio of 4: 3 is performed in an ordinary TV receiver, but in the expansion / compression of the image at that time, By similarly expanding and compressing the image mask, this method can be used effectively, and the same effect can be obtained.

  Next, an outline of a TV synchronization service to which the recording / playback apparatus and service server of the present invention are applied will be described by taking an information providing service in a drama program as an example. FIG. 12 is a diagram for explaining the outline of the TV synchronization service. This figure shows a drama program as an example of a TV program. This drama program includes an information providing service. That is, the service type 111 of the service control data 100 indicates the information providing service. FIG. 12A shows a time chart of this drama program. 12B to 12D show images displayed on the screen 200 of the display device 28 at each time in the time chart of FIG.

  Referring to FIG. 12A, this drama program is shown in FIG. 12B from the HOC (Head of Contents) indicating the start to the target video start time (TC1) 105 of the service control data 100. 207 is displayed on the screen 200 of the display device 28. Thereafter, for the video playback time (α) 106 from the target video start time (TC1) 105 to the target video end time (TC2) 107, the video 208 shown in FIG. 12C is displayed. Thereafter, from the target video end time (TC2) 107 to the end of the drama program, the video 209 shown in FIG. 12D is displayed.

  With reference to FIG. 12B, the information providing service is not performed during the time (target video start time (TC1) 105) during which the video 207 is displayed. Therefore, the hint message is not displayed, and only the normal video data 207a is displayed.

  Referring to FIG. 12C, the video 208 includes a screen mask, normal video data 208a, a hint message 208b as image data for synthesis, a pointer 240, and a click point 251. In this case, in the service control data, dummy positions 117-1 to 117-n and corresponding position mask designations 118-1 to 118-n correspond to the click point 251. In this case, the dummy position 117-1 is the position (coordinates) of the click point 251 displayed on the screen of the display device 28. The position mask designation 118-1 corresponds to the dummy position 117-1 and serves as a screen mask for determining coordinates for designating the position of the click point 251. The hint message 112 is a message displayed on the video 208. The return Web URL 127 is a URL for providing information of the service server 2. When there are a plurality of click points for providing information, dummy positions 117-1 to 117-n and corresponding position mask designations 118-1 to 118-n are set, and a return Web URL 127 is also set for each click point. In this figure, when the viewer clicks a click point 251 on the screen 200 with a pointer 240, the recording / playback apparatus 1 can access the URL corresponding to the service server 2 and provide information.

  Referring to FIG. 12D, the information providing service is not performed during the time when the video 209 is displayed. After the information is provided or when the viewer does not provide the information, a video 209 that is a continuation of the video 208 is displayed. Therefore, only normal video data 209a is displayed.

  When other information is provided as a TV synchronization service in other scenes in the drama program, service control data is prepared for each scene. Also, when a CM program for performing a TV synchronization service is inserted in the middle of a drama program, service control data corresponding to the CM program is prepared.

  FIG. 13 is a schematic diagram illustrating a case where a click point is clicked. FIG. 13A shows a situation where the viewer clicks the click point 251 on the screen 200 with the pointer 240 in FIG. FIG. 13B shows a message screen 250 displayed on the screen 200. In response to the viewer clicking the click point 251 with the pointer 240, the recording / playback apparatus 1 accesses a predetermined URL of the service server 2, acquires the corresponding data in the URL, and displays it as a message screen 250. indicate. Here, the types of information that can be provided for the brick house 253 in the video 208 are displayed.

  FIG. 14 is a schematic diagram illustrating a case where the message screen is clicked. FIG. 14A shows a screen 261 displayed when “1) a brick house location map” is clicked in the information provision. FIG. 14B shows a screen 262 displayed when “2) Brick house history” is clicked in the information provision. FIG. 14C shows a screen 263 that is displayed when “3) Brick house visit tour” is clicked in the information provision. The screen data displayed in FIGS. 14A to 14C is acquired by accessing the URL indicated in the return Web URL 127. The information providing function in FIGS. 13 and 14 can be realized by the Web browser function of the TV synchronization service control unit 17. In this case, the original video 208 is temporarily stopped.

  Next, the operation of the embodiment of the TV content synchronization system to which the recording / playback apparatus and service server of the present invention are applied (the operation method of the recording / playback apparatus, the operation method of the service server, and the embodiment of the TV content synchronization method). explain. 15A and 15B are flowcharts showing the operation of the embodiment of the TV content synchronization system to which the recording / playback apparatus and service server of the present invention are applied.

First, an operation for recording a TV program of the broadcasting system 3 by the recording / reproducing apparatus 1 will be described.
Broadcast system 3 broadcasts a TV program (step S01). Then, the broadcast system 3 transmits the TV program data to the outside (step S02). However, the TV program data here does not need to include data relating to the TV synchronization service, and may be the same as the conventional TV program data. The recording / playback apparatus 1 receives the TV program data with the antenna 25. In addition, the broadcast server 51 of the broadcast system 3 generates service control data related to a TV program that performs a TV synchronization service among the TV programs to be broadcast. Then, the EPG data of the TV program that performs the TV synchronization service and its service control data are transmitted to the service server 2 (step S03). The service server 2 stores the EPG data in the EPG / search server 42 and the service control data in the control server 41. At this time, the EPG data and the service control data are associated with each other.

  Note that generation and transmission of service control data may be performed before the broadcast or after the broadcast. Further, after the broadcast, the service control data may be updated as appropriate. In the present invention, when performing the TV synchronization service, it is not necessary to embed data specially in the TV program data or to modify the TV program data. That is, a TV synchronization service can be provided as a retrofit for a program that has already been broadcast. Therefore, the TV program data can be easily produced, and the contents of the TV synchronization service can be corrected while watching the viewer's reaction.

  The antenna 25 receives TV program data indicating a TV program from the broadcasting system 3 by radio waves and supplies it to the receiving unit 11. The receiving unit 11 detects a radio wave indicating TV program data and acquires TV program data. Based on the user input (example: input to the remote control input control unit 16 by remote control operation), the recording / playback unit 14 records the TV program data (step S05). Accordingly, the recording / playback unit 14 stores the TV program data in the recorded program file storage unit 23 as a recorded program file. The EPG separation control unit 15 extracts EPG data from the TV program data to be recorded, and stores it in the EPG data storage unit 22 (step S06). At this time, the EPG separation control unit 15 associates the EPG data in the EPG data storage unit 22 with the recorded program file in the recorded program file storage unit 23.

Next, an operation for searching for a TV program providing a TV synchronization service in the recording / playback apparatus 1 will be described.
The recording / playback unit 14 acquires EPG data in the EPG data storage unit 22 based on user input (example: input to the remote control input control unit 16 by remote control operation) and stores it in the recorded program file storage unit 23. A list of EPG data of the recorded program file is displayed on the display device 28 (step S11). FIG. 16 is a schematic diagram of a screen displaying a list of recorded program files. On the screen 280, a recorded program file list 281, an operation button 282, and a TV synchronization service control button 283 are displayed. A list 281 shows EPG data for specifying a recorded program file stored in the recorded program file storage unit 23 in a table format. An operation button 282 indicates a button for performing selection or reproduction with the pointer of the pointing device of the remote controller. The TV synchronization service control button 283 is a button for searching for a recorded program file displayed in the list 281 that is performing the TV synchronization service.

  When the TV synchronization service control button 283 is pressed by the user's remote control operation, the incoming remote control input control unit 16 receives remote control operation data (TV synchronization service search signal) indicating the content of the user's remote control operation from the remote control. Is output to the TV synchronization service control unit 17 (step S12). In the case of the TV synchronization service search signal, the TV synchronization service control unit 17 inquires TV programs that can receive the TV synchronization service among the TV programs stored in the recorded program file storage unit 23. To instruct. Specifically, EPG data associated with the TV program stored in the recorded program file storage unit 23 is read from the EPG data storage unit 22, and the same EPG data as the EPG data is stored in the EPG / search server 42 of the service server 2. Search whether there is. The TV synchronization service control data detection unit 20 accesses the service server 2 via the Internet connection unit 21 and the network 4 based on an instruction from the TV synchronization service control unit 17. Then, an inquiry is made to the EPG / search server 42 as to whether or not the EPG data in the EPG data storage unit 22 is included in a TV program (EPG data) for which service control data is registered (step S13). Based on the inquiry from the recording / playback apparatus 1 (user), the EPG / search server 42 determines whether there is a TV program stored in the recorded program file storage unit 23 among the TV programs with registered service control data. Search for. More specifically, the EPG data of the EPG data storage unit 22 is searched for in the EPG data of the EPG / search server 42 (step S14). The EPG / search server 42 transmits the search result to the recording / playback apparatus 1 (step S15).

  The TV synchronization service control data detection unit 20 that has received the search result via the network 4 and the Internet connection unit 21 determines whether there is a TV synchronization service for the EPG data in the EPG data storage unit 22 based on the search result. (Step S16). If there is a TV synchronization service, the EPG / search server 42 is requested for service control data corresponding to the corresponding EPG data (step S17). The EPG / search server 42 notifies the control server 41 of the corresponding EPG data together with the identification data of the recording / playback apparatus 1. The control server 41 extracts service control data corresponding to the corresponding EPG data (step S18) and transmits it to the recording / playback apparatus 1 via the network 4 (step S19).

  The TV synchronization service control data detection unit 20 receives the service control data and stores it in the control data storage unit 24 (step S20). In addition, the EPG data corresponding to the service control data is output to the TV synchronization service control unit 17. The TV synchronization service control unit 17 outputs EPG data corresponding to the service control data to the recording / playback unit 14 via the playback synchronization control unit 18. Based on the EPG data, the recording / playback unit 14 updates the EPG data list of the recorded program file and displays it on the display device 28 (step S21). FIG. 17 is a schematic diagram of a screen displaying a list of recorded program files after update. In the recorded program file list 281 on the screen 280, for example, a mark 286 that can newly receive the TV synchronization service is added to the # 2 TV program (EPG data). Also, a TV synchronization service button 285 is provided so that a TV synchronization service can be received when the # 2 TV program is reproduced. The operation button 282 and the TV synchronization service control button 283 are the same as those in FIG.

  However, when displaying the updated recorded program file list after a while after receiving the service control data, the TV synchronization service control unit 17 checks the validity period 113 of the service control data, and the validity period has passed. Does not display the mark 286 that can receive the TV synchronization service. Even in this case, by executing the operations of steps S11 to S21 again, if there is an updated TV synchronization service, a mark 286 that can receive the updated TV synchronization service is newly displayed. As described above, according to the present invention, it is possible to provide a new TV synchronization service whose contents are changed after the valid period has passed.

Next, an operation for receiving the TV synchronization service in the recording / playback apparatus 1 will be described.
When the TV program # 2 is selected by the user's remote control operation and the reproduction of the TV synchronization service button 285 and the operation button is pressed, the remote control input control unit 16 displays remote control operation data indicating the content of the user's remote control operation. (TV synchronization service use signal + reproduction signal) is received from the remote controller and output to the TV synchronization service control unit 17 (step S31). The TV synchronization service control unit 17 selects the service of the selected TV program based on the EPG data of the selected TV program, the program code 101 of the service control data in the control data storage unit 24, the program broadcast date and time, and the channel 102. Control data is acquired from the control data storage unit 24. Then, the reproduction synchronization control unit 18 is instructed to reproduce the TV program. Further, the marker setting / detecting unit 19 is instructed to operate in synchronization with the reproduction of the TV program. The playback synchronization control unit 18 instructs the recording / playback unit 14 to play back the TV program in synchronization with the operation of the marker setting / detection unit 19. The recording / playback unit 14 takes out the recorded program file of the TV program from the recorded program file storage unit 23 based on an instruction from the playback synchronization control unit 18, and synchronizes with the operation of the marker setting / detection unit 19. The file is reproduced (step S32).

  Since the marker setting / detecting unit 19 is synchronized with the recording / reproducing unit 14, the marker setting / detecting unit 19 grasps the time (HOC) when the recording / reproducing unit 14 starts reproducing the recorded program file. The marker setting / detecting unit 19 receives service control data from the TV synchronization service control unit 17 (example: in the case of a quiz, service type 111, hint message 112, dummy positions 117-1 to 117-n, position mask designation 118-1). -118-n, correct position specification 121, position mask specification 122, score 123, position display flag 125), image data for synthesis is generated. Then, when the target video start time (TC1) 105 is reached based on the service control data (step S33), the generated image data for synthesis is synchronized with the playback operation of the recording / playback unit 14 and the image synthesis unit 13 Output to. The image composition unit 13 synthesizes the video data and the composition image data and outputs them to the display device 28 (step S34). The display device 28 displays the synthesized video.

When the synthesized video is displayed on the display device 28, if there is an input to the remote control input control unit 16 by the user's remote control operation (step S35), the TV synchronization service control unit 17 performs processing related to the input. (Step S36). For example, in the case of a quiz, when the pointer of the pointing device of the remote controller clicks on the point specified by the correct position designation 121 and the position mask designation 122, the TV synchronization service control unit 17 recognizes that the quiz has been won. In this case, the TV synchronization service control unit 17 extracts the ID indicating the user (recording / playback apparatus 1) to be displayed, the acquired score (score 123), and the URL for performing the quiz process (return WebURL 127). In the case of providing information, a URL for providing information (return Web URL 127) is extracted. Then, request data including the extracted information is transmitted to the service server 2. The service server 2 executes processing related to the request content based on the request data (step S38). For example, in the case of a quiz, based on the user ID, the score acquired in the personal score management server 43 is recorded, and the total score acquired by the user ID is calculated. In the case of information provision, the requested information and related information are acquired by accessing an external server or its own database. Thereafter, result data indicating the result of executing the processing related to the request content is returned to the recording / reproducing apparatus 1 (step S39). For example, in the case of a quiz, the personal score management server 43 transmits the total score acquired by the user ID to the recording / playback apparatus 1. In the case of providing information, the requested information (data, URL, etc.) is transmitted to the recording / playback apparatus 1. The TV synchronization service control unit 17 displays the result on the display device 28 (step S40). At this time, the recording / playback unit 14 may completely stop the playback of the recorded program file, or may pause and display it on the still screen. For example, in the case of a quiz, the marker setting / detecting unit 19 synthesizes the score obtained by the user, its message, and a symbol based on the received total score and score 123, and outputs the synthesized image data to the image synthesizing unit 13. . The image synthesizing unit 13 synthesizes the image data for synthesis with the video data (still screen) and causes the display device 28 to display it. In the case of providing information, the recording / playback unit 14 completely stops playback of the recorded program file, and displays an information providing screen (such as an information providing URL HP (homepage)). In either case, the return is performed by the user's remote control operation (example: playback button operation). When returning, the marker setting / detecting unit 19 and the recording / playback unit 14 are synchronized.
Steps S33 to S40 are repeated until the TV program ends (step S41).

  Through the above operation, the TV content synchronization method to which the recording / playback apparatus and service server of the present invention are applied can be implemented. According to the present invention, an interactive TV synchronization service can be received even for a TV program recorded by a viewer. The contents and service period of the TV synchronization service can be freely changed after the TV program broadcast ends. In addition, a TV synchronization service can be provided for the TV program without special processing of the TV program broadcast data itself.

  Note that the coordinate setting using the screen mask in the above description has one stage of the screen mask, but the screen mask may have a plurality of stages. FIG. 18 is a diagram for explaining an outline of a method for setting coordinates on the screen. This figure shows the case where the screen mask has two stages. First, as a first step, the point 270 is specified by coordinates (h6, v3) using the screen mask 221 in the screen 200 on the left side. Next, as a second stage, the point 271 is specified by coordinates (h5, v3) using the screen mask 225 at the point 270 on the right side. In this case, the point 271 is specified by the screen mask 221: coordinates (h6, v3) × screen mask 225: coordinates (h5, v3). In this case, the point 271 can be specified in more detail with less information. If the same screen masks 221 and 225 are used, the point 271 can be specified in more detail with a smaller amount of information.

  The service control data in this case will be described. FIG. 19 is a diagram showing the contents of the service control data. The service control data 100a is basically the same as the service control data 100.
