In the present embodiment, the video data reproduced from the disc 90 and the video data supplied from the camera device 50 will be described as compressed video data. However, it is needless to say that these may be video data that has not been compression-encoded.

3. Configuration of Camera Device FIG. 3 is a block diagram illustrating a configuration example of the camera device 50. The lens unit 51 is a subject image (real-time world image)
As described above, it is possible to capture the scenery and the site described above. An imaging light beam incident through the lens unit 51 is transferred to a CCD (Charge Coupler) serving as a photoelectric conversion element.
ed Device) 52. The CCD 52 is provided with pixels corresponding to, for example, three primary colors of R, G, and B. The pixels corresponding to the respective colors are arranged according to a predetermined rule on the plane of the CCD substrate on which the imaging light rays incident from the lens unit 51 are imaged, and form a two-dimensional image forming area.

Since the electric signal based on the electric charge read from the CCD 52, that is, the electric charge according to the exposure from the subject is weak, the electric signal is supplied to the amplification / gain adjustment unit 53 and amplified. Then, the sampled and held process is performed on the amplified signal, the gain is further adjusted, and the signal is output to the A / D converter 54. The A / D converter 54 converts the input analog signal into digital data, and
5 The video encoding unit 55 can encode the digital data supplied from the A / D converter 54. As an encoding method, for example, MPE
A compression technique such as G2 is used. The communication unit 56 is configured as shown in FIG.
Is provided as an interface for performing data communication with the disk drive device 80 via the communication line 110 shown in FIG. Video data can be transmitted.

The control section 57 is composed of, for example, a microcomputer, and controls the entire camera device 50 via a control bus 58. For example, it is possible to control the timing for synchronizing the capturing of the imaging light beam in the CCD 52, the A / D conversion processing in the A / D converter 54, and the encoding processing in the video encoding unit 55. I have. Further, when detecting the reception of the access request information for the camera device 50, the communication unit 56 is controlled so that the video data encoded by the video encoding unit 55 is transmitted.

The control section 57 controls the lens driving system of the lens section 51 so that focus driving and iris adjustment driving can be executed.

4. Server Device Configuration, Address Table Configuration FIG. 4 is a diagram illustrating a configuration example of the server device 60.
The communication section 61 can perform data communication with the disk drive device 80 via the communication line 110. In the database 62, for example, an address table associated with the disk ID is recorded. The control unit 63 controls the communication line 1 via the control bus 64.
10 and the management of the database 62 can be performed. For example, when a transmission request or a disk ID is received from the disk drive device 80, an address table corresponding to the disk ID is searched from the database 62, and control for transmitting to the disk drive device 80 is performed. As a result, the address table is transmitted from the communication unit 61 to the disk drive device 80 that has made the transmission request.

FIG. 5 is a view for explaining a configuration example of the address table. As described above, in the database 62, for example, an address table is recorded in association with the disk ID, but FIG. 5 shows an address table # 1 corresponding to the disk ID "001". In each of the address tables # 1, # 2,..., An index corresponding to, for example, one content, or a division unit (eg, a program, a chapter, a scene, or the like in the present embodiment) obtained by dividing one content by time. Information and address information of the camera device 50 corresponding to the index information are stored. In the case of the address table # 1, as shown, the address information of the camera device 50 on the communication line 110 corresponds to the content or the index information corresponding to the program / chapter / scene in the content. It is attached. This address table is, for example, information that is set in advance (or at a certain point after the content creation) in accordance with the content when the content recorded on the disc 90 is created.

As shown in the figure, in the address table # 1, three pieces of camera address information (# 1, # 2, and # 4) are respectively provided for index information # 1, # 2, # 3, and # 4.
3), but these camera address information correspond to three camera devices 5 that are capturing the same real-time world video.
It corresponds to 0. This is the camera device 5
0 assumes that data communication with the disk drive device 80 cannot be performed (for example, a system busy or a trouble such as a failure). That is, for example, when the index information # 1 is instructed at the time of reproducing the content in the disk drive device 80, it is only necessary to be able to communicate with any of the three camera devices. Note that three camera devices 50 that capture the same real-time world image are not necessarily arranged. Therefore, the camera address information is also prepared corresponding to the camera device 50 in which the camera address information is arranged.

By constructing such an address table # 1 and associating the index information with the camera address information, in the content recorded on the disk 90, the content corresponding to the index information # 1 contains "camera address" as the camera address. 12.34.567.1 "and" 12.3
Any one of 4.567.2 and 12.34.567.3 corresponds, and the content corresponding to the index information # 3 is “34.56.5789.
1 "" 34.56.789.2 "" 34.56.78
9.3 ". Then, after the address table is transmitted to the disk drive device 80 at the time of content reproduction, one of the camera addresses is selected by setting a pointer to the address table in the disk drive device 80 as described later. You.

When the index information # 1 is specified, for example, as shown in FIG. 6, the camera address "12.3"
4.567. Based on “x”, data communication is performed with the camera device 50a that captures an image of a city landscape. Similarly, when the index information # 2 is specified, data communication is performed with the camera device 50b that is capturing the scenery of the city based on the camera address “23.45.678.x”. When the index information # 3 is specified, data communication is performed with the camera device 50c that is capturing the seascape based on the camera address “34.56.789.x”. Further, when the index information # 4 is specified, the camera address "45.67.89"
1. Based on “x”, data communication is performed with the camera device 50d that is capturing the mountain landscape. That is, according to the address table shown in FIG. 5, when the content is played back, the real-time world video is supplied to the disk drive device 80 in the order of, for example, city, town, sea, and mountain based on the index information. Will be done.

Also, as shown in FIG.
In addition to address table # 1, other disk I
Address tables # 2, # 3, # 4,... Corresponding to D
Is recorded, and an address table corresponding to the disk ID transmitted from the disk drive device 80 is selected.

As described above, in the server device 60, the address tables corresponding to the respective disks 90 on the market are centrally managed. Thus, the address table managed by the server device 60 can be reflected on each of the disks 90 via the communication line.

[0062] 5. Disc Format FIG. 7 is a diagram schematically showing a recording area formed on the disc 90. In the recording area of the disc 90, a lead-in area, a volume area, and a lead-out area are formed.

As shown in FIG. 8, for example, as shown in FIG. 8, the lead-in area stores various information (TOC (Ta
bleOf Contents) are recorded. The information recorded in the lead-in area is, for example, index information such as start time and end time as each piece of information (program, chapter, scene) of the content recorded on the disc, and capacity information of the disc 90. Recording layer number information (one layer or two layers), track path direction information (parallel or opposite), for example, recording start / end position information in a volume area indicated by a sector number, a disk ID for identifying the disk, and the like. Have been. Further, in the present embodiment, a camera link identification flag indicating whether or not the content recorded on the disc is linked to the real-time world video supplied from the camera device 50, and an address table corresponding to the disc are recorded. Server device 6
0 address information and the like are recorded.

As described with reference to FIG. 9, a volume management area, a video area, and other areas are formed as needed. The lead-out area is an area for notifying the disk drive device 80 of the end of content reproduction.

FIG. 9 is a schematic diagram for explaining each area formed in the volume area. As shown in FIG. 9A, the volume area includes a volume management area in which management information of the entire volume area is recorded, content such as a movie, and various types of content corresponding to the content. It is formed by an image area in which control information is recorded.

The volume management area is a UDF (Universa
(l) A management format is described using a (Disk Format) bridge, and it is possible to access contents recorded in the video area even by using a computer device. The video area is a video manager (VM
G ... Video Manager) and one or more video title sets (VTS ... Video Title Set).

As shown in FIG. 9B, the video manager includes video manager information (VMGI... Video Manager Information) and volume menu video information (VMGM_VOBS.

UP). The video manager information includes one or more video title sets VTS # 1 recorded in the video title set area,
Are used as control information for executing a volume menu display process in which information on the contents of VTS # 2, VTS # 3,... Is displayed. The volume menu video information (VMG_M_VOBS) includes a video object set (VBO_VBO) for displaying the volume menu.
S. Video Object Set). Note that the video object set is a video object unit (VOBU... Video Object Unit) formed by reproduction data (video data, audio data) in units of about 0.5 to about 1.0 second. Information unit. The video object unit will be described later. Following the volume menu video information, the backup video manager information (V
MGI_BUP), and the same contents as the video manager information described above are recorded.

The video title set shown in FIG. 9A can be a unit corresponding to a content such as one movie. Therefore, when only one movie is recorded as content on the disc 90, at least one video title set is recorded in the video title set area. Also, the total number in the video title set area is 9
Nine video title sets can be recorded. In the present embodiment, the division units in the video title set are also referred to as programs, chapters, scenes, and the like.

The contents of each video title set are shown in FIG.
It is shown in (c). Video Title Set Information (VTSI ... Video Title SetInformati

The same contents as I) are recorded.

FIG. 10 is a schematic diagram for explaining the structure of video title video information. Video title video information (VT
STT_VOBS) includes one or more video objects (VOB # 1 to VOB # 1) as shown in FIG.
VOB # n). Further, one video object is composed of one or more cells as shown in FIG. These cells are playback units to which unique identification information (ID # 1, # 2, # 3,...) Is attached as real-time data. Each cell is composed of two or more video object units, as shown in FIG. That is, the video object unit is managed on a cell basis. Further, as shown in FIG. 10D, the video object unit is formed by four types of packs: a navigation pack NVP, a video pack VP, an audio pack AP, and a sub-picture pack SP. Then, at the beginning of each cell, a navigation pack NVP is arranged, and subsequently, video packs VP, audio packs AP, and sub-picture packs SP for an integer number of GOPs (Groups Of Pictures) are arranged.

The navigation pack NVP is a PCI (Presentation Control Informatio) for controlling the reproduction of video and audio in the video object unit.
n) and DSI (Data Search Inf) for searching data
ormation). Video Pack VP
Is main video data, for example, video data compressed by a data compression method such as MPEG is packed. The sub-picture pack SP is obtained by packing video data for adding a main video such as a subtitle of a movie as auxiliary information to the main video data of the video pack VP. Audio Pack AP
Indicates that audio data is packed.

FIG. 11 is a diagram for explaining the structure of the pack. As shown in FIG. 11A, one pack includes a pack header and a packet, and is formed with a data length of 2048 bytes as a data unit defined as one logical block on the disk 90. Information such as a pack start code and a system clock reference (SCR) is described in the pack header. The pack start code is a code indicating the start of the pack, and the system clock reference is information synchronized with the reproduction data and is information indicating the elapsed reproduction time for the entire disk drive device 80.

FIG. 11B is a diagram for explaining the packet structure in the video pack VP, the sub-picture pack SP, and the audio pack AP. The packet header is
The packet includes a packet start code indicating the start of a packet, a stream ID indicating the type of data recorded in the packet, a packet length, and a substream ID. Therefore, in the stream ID, identification information indicating that the data recorded in the packet is one of video, sub-picture, and audio is recorded. Also, for example, stuffing bytes (dummy data) may be inserted into the video pack VP as necessary, and in such a case, stuffing byte length information is recorded in the packet header.

The navigation pack NVP is shown in FIG.
As shown in FIG. 1C, one packet is divided and PCI and DSI are recorded. That is, when the stream ID indicates the identification information indicating the navigation pack NV, the packet headers # 1 and # 2 are formed. Then, identification information indicating that PCI is recorded in packet # 1 is recorded in substream ID # 1, and similarly, DSI is recorded in packet # 2 in substream ID # 2. The identification information is recorded.

FIG. 12 is a diagram for explaining the relationship between the video object unit and the cell. As described above, FIG.
The video object units VOBU # 1, VOBU # 2,... Shown in (a) and (b) are managed in cell units. Then, as shown in FIG. 12C, one or more cells are managed as program PG # 1... Program PG # n. Further, a combination of the plurality of programs PG continuously can be managed as a program chain PGC. For example, taking a movie as an example, the program PG is a unit that divides contents according to a story, and is also called a chapter. In the present embodiment, it is also referred to as “scene”. The program chain PGC has a pre-command executed before reproducing the first cell and a post-command executed after reproducing the last cell.

In the program chain PGC, the reproduction order of the cells forming the program PG is specified, and the reproduction order is managed by attaching a cell number separately from the cell-specific identification information (cell ID). are doing. That is,
In FIG. 12C, the cells corresponding to the cell numbers are reproduced in the order of the cell numbers # 1 to #n in the program PG # 1.

For example, management information related to the program chain, such as recording position information of a video object unit managed in the program chain, is managed by the video title set information shown in FIG. Therefore, in the disk drive device 80, when the reproduction of the video title set is executed, the cell arrangement is performed with reference to the video title set information as managed by the program chain.

FIG. 13 is a diagram for explaining the relationship between real-time data and cells reproduced by the program chain. FIG. 13A shows an array of cells (ID # 1, ID # 2, ID # 3,...) Which are used as real-time data. For example, the content recorded on the disc 90 is one movie, and one video title set is one.
When managed by the program chains PGC # 1, the cells are reproduced in the order recorded on the disk 90, that is, in the same order as the cell ID, as shown in FIG. Therefore, the cell ID and the cell number match in the reproduction order. In the case where a plurality of contents having different stories and the like are recorded in one video title set, for example, FIG.
As shown in (c), the program PG is managed by separate program chains PGC # 2 and PGC # 3. In this case, each program chain PG
C # 2 and PGC # 3 arrange cells to be reproduced in the reproduction order according to the program PG. For example, in the program chain PGC # 2, the cell IDs are "# 4" and "#
2 ","# 6 ","# 7 ","# 3 ","# 5 ","# 8 ". In the program chain PGC # 3,
Cell ID is “# 7” “# 3” “# 4” “# 2” “# 5”
They are arranged in the order of “# 8” and “# 6”.

Further, as shown in FIG. 14, the programs constituting the program chain PGC can be managed in units of PTT (Part Of Title). I have. In this case, a PTT number is assigned to the program, and the program is accessed by a user operation (for example, during reproduction or cueing).
The processing is executed based on the PTT number.

As described above, the program chain and the cells can be managed so that the temporal structure of the video title set and the reproduction order for each section can be arbitrarily set. As a result, it becomes possible to select a parental level (viewing restriction) and an angle of a reproduced video on a program basis or on a cell basis.
In the case of a movie, for example, the progress of the story can be selected.

6. Control During Content Playback Hereinafter, according to the flowchart shown in FIG. 15, when disc discrimination, acquisition of an address table, camera connection processing, and the like are performed as initial processing when the disc 90 is loaded in the disc drive device 80. Next, an example of processing steps executed by the system controller 10 will be described.

The system controller 10 controls the disk 9
0 is detected, or when it is detected that the disc 90 is loaded when the power is turned on (S001), the loaded disc (for example, DV
D, CD, CD-ROM, etc.) (S00
2). For example, a process for reading the TOC is executed as an initial process when the disc is loaded. In this case, for example, by executing each servo control such as a spindle servo, a focus servo, and a tracking servo and stabilizing each servo, it is possible to shift to a state where data can be read. . That is, each servo is set based on the servo characteristics of various disks. Therefore, when the servo is settled, the disc can be identified based on the servo characteristics.

The system controller 10 determines in step S
Subsequent to the disc identification process of 002, TOC is read (S003), and a camera interlocking identification flag is detected (S004). Further, based on the detected camera linkage identification flag, it is determined whether or not the disk 90 is a camera linkage disk (S005). If it is determined that the disk is a camera-linked disk, the address information of the server device 60 recorded in the TOC is detected (S10).
006) Then, the communication unit 31 is requested to make a connection request to the server device 60 (S007).
To start the data communication process. When the disk 90 is not a camera-linked disk, the system operation with the server device 60 and the camera device 50 is not performed, and the disk drive device 80 performs the reproduction operation alone (S005 → S018).

When the system controller 10 starts the data communication process with the server device 60 as described above, it first transmits a disk ID to the server device 60 (S008). Then, it is determined whether or not the address table transmitted from the server device 60 has been received in response to the transmission processing (S009). That is, it waits for reception of the address table. If it is determined that the address table has been received,
It is stored in the RAM 41 and decrypted (S010). Note that the data communication process with the server device 60 is terminated when the address table is received, but a process example in which the data communication process with the server device 60 is continued after this time is also conceivable.

Subsequently, the address table pointers (index pointer, camera address pointer) are initialized in the RAM 41 (S011). For example, FIG.
, The initial value of each pointer is “1” and “1”, respectively. In this case, the designated camera address is “12.34.577.1”. When the system controller 10 initializes the pointer in this way, the communication unit 31 requests connection to the camera address specified by the pointer (S012). Then, based on the response from the camera device that has made the connection request, it is determined whether the camera device is currently connectable, that is, whether data communication is possible (S013).

If it is determined that the connected camera device can communicate, data communication with the camera device is started (S014). If it is determined in step S012 that the camera device that has requested the connection cannot communicate,
The camera address pointer is incremented (S01
7) Return to step S012, and make a connection request to the camera address indicated by the updated pointer. That is, for example, the next camera device that is capturing the same scenery is selected and a connection request is made. If it is determined that the camera device can communicate, data communication with the camera device is started (S014).

Subsequently, the system controller 10 increments the index pointer and initializes the address pointer (S015). Then, it is determined whether or not the incremented index pointer is the maximum value in the address table (S01).
6) If it is determined that it is not the maximum value, step S01
Return to 2. Then, a connection request is made to the camera address indicated by the pointer updated in step S015. That is, the camera corresponding to the next index (scene or the like) is selected by incrementing the index pointer. Also in this case, step S
If it is determined in step 012 that the connected camera device cannot communicate, the address pointer is incremented (S017), and the process returns to step S012 to make a connection request to the camera address indicated by the updated pointer. Thereby, for example, the next camera device that is capturing the same scenery is selected.

In this way, a connection request is made to the camera address indicated in the address table, and in step S016, the index pointer is set to the maximum value, that is, the connection request is made to the camera addresses for all indexes. If it is determined that the reproduction has been performed, the process proceeds to the content reproduction process (S018).

The flowchart shown in FIG. 15 has been described by taking as an example the processing step of connecting to all the camera devices that perform data communication before shifting to the content reproduction operation. However, as a connection processing method to the camera device, a scene (a program, a chapter) to be reproduced at any time after the reproduction operation is started is identified,
A connection request may be made to a camera address corresponding to a scene.

FIG. 17 shows that the disk drive device 80
16 is a flowchart illustrating an example of a processing operation performed by a control unit 63 of the server device 60 when the processes illustrated in steps S007 and S008 illustrated in FIG. 15 are performed.
During operation, the server device 60 is in a standby state for determining whether a connection request transmitted from the disk drive device 80 via the communication line 110 has been received (S).
101). When determining that the connection request has been received in the standby state, the control unit 63 starts data communication processing with the disk drive device 80 that has transmitted the connection request, and receives the disk ID transmitted from the disk drive device 80. It is determined whether or not it has been performed (S102). When determining that the disk ID has been detected, the control unit 63 searches the database 62 for an address table corresponding to the detected disk ID (S103). Communication unit 6
1 to transmit the selected address table to the disk drive device 80 that has received the connection request (S104). This is the return process to the disk drive device 80 that has received the connection request. Then, after transmitting the address table, the communication process with the disk drive device 80 that has received the connection request is terminated. As a result, the disk drive device 80 performs step S in FIG.
Through the steps shown in steps S009 and S010, an address table can be obtained.

FIG. 18 is a flowchart illustrating an example of a processing operation executed by the control unit 57 of the camera device 50 when the disk drive device 80 executes the process shown in step S012 shown in FIG. In the camera device, the disk drive device 8 is connected via the communication line 110 during operation, similarly to the server device 60 described above.
It is in a standby state for determining whether or not a connection request transmitted from 0 has been received (S201). If the control unit 57 determines that a connection request has been received in this standby state, the control unit 57 determines whether the camera device is currently in a connectable state, that is, in a communicable state (S202). This connection request is a connection request made in the process shown in step S012 in FIG. If it is determined that the connection is possible, the disk drive 8
A data communication process with S.0 is started (S203), and real-time world video data is transmitted (S204). After starting transmission of the real-time world video data, the control unit 57 determines whether or not a disconnection request from the disk drive device 80 has been detected (S205). The data communication process with the drive device 80 is completed (S206), and a connection request is awaited. The disconnection request is transmitted from the disk drive device 80 when the reproduction of the content recorded on the disk 90 is completed in the disk drive device 80 or when the reproduction of the content is stopped by a user operation. It is said.

If it is determined in step S202 that communication is not possible in response to the connection request from the disk drive 80, communication disable information is transmitted to the disk drive 80 (S207). For example, the situation in which the camera cannot be connected includes a busy state in which communication processing with another disk drive device 80 is being performed, a state in which communication processing cannot be performed due to a failure, and the like.

7. Video Synthesizing Process FIG.
7 is a flowchart illustrating an example of a combining process performed by the system controller 10 when a content reproduction process is performed after the initial process illustrated in FIG. When the reproduction of the content is started (S301), it is determined whether or not composite identification information indicating whether or not to combine the recorded video data with the real-time world video data is detected (S302). The composite identification information is transmitted to the video data decoding unit 2 as described above.
9 is information extracted in units of frames, for example. If it is determined that the composite identification information has been detected, the real-time world video data for one frame, for example, decoded by the video data decoder 33 is supplied to the synthesizer 30 (S
303) Then, the synthesizing unit 30 synthesizes the recorded video data and the real-time world video data (S304). The combining process will be described later. The output video data generated by being combined in step S304 is subjected to signal conversion processing in the signal conversion processing unit 34 to be converted into a television signal (S305).
If it is determined in step S302 that the combined identification information has not been detected, only the recorded video data is output from the combining unit 30, and the signal conversion processing unit 34 converts the recorded video data into a television signal. Is converted. Therefore, the content reproduced from the disc 90 is output as it is.

FIGS. 20 (a), 20 (b) and 20 (c) are schematic diagrams for explaining the synthesizing process executed by the synthesizing unit 30 in step S304 of FIG. Is shown. In this figure, frames corresponding to the passage of time t are shown in an array. In addition, in FIG. 20A, when “1” is indicated as the combination identification information, it indicates that the frame is to be combined. As shown in FIG. 20A, the frames of the recorded video data read from the disk 90 and decoded by the video data decoding unit 29 are
n, n + 1, n + 2, n + 3, n + 4, n + 5, n + 6
..., the combined identification information corresponding to frames n + 2, n + 3, and n + 4 is “1”. Therefore, the combining process is performed on these three frames, and the combining process is not performed on the other frames whose combination identification information is set to “0”. Also, the real-time world video data decoded by the video data decoding unit 33 is, as shown in FIG.
In the case where m + 1, m + 2, m + 3, m + 4, m + 5, and m + 6 are set, frames n + 2, n shown in FIG.
Frames m + 2, m + 3, and m + 4 corresponding to the timings at which the +3 and n + 4 frames are read are synthesized. Therefore, the output video data output from the synthesizing unit 30 is, as shown in FIG.
Frames n, n + 1, (n + 2) + (m + 2), (n +
3) + (m + 3), (n + 4) + (m + 4), n + 5,
n + 6.

FIGS. 21 (a), 21 (b) and 21 (c), and FIGS.
(A), (b), and (c) are schematic diagrams illustrating examples of a recorded video, a real-time world video, and an output video (composite video). In addition,
In the following description, a character is a moving part in an image such as a person or a car, and a background is a part shown behind the character. The recorded video shown in FIG.
Characters 101 and 102 related to the contents of a certain scene are displayed as images read out from. Also,
The real-time world image shown in FIG. 21B is, for example, a landscape of a mountain in the morning, for example, the sun 110, clouds 111,
Mountain 112 is shown. Then, by synthesizing these images, as an output image, the morning mountain scenery (sun 110, clouds 111,
The characters 101 and 102 are displayed with the mountain 112) as a background. Further, when the real-time world image shown as a landscape of a mountain at night shown in FIG. 22B is combined with the recorded image shown in FIG. ), The character 1 is set against the background of the mountain landscape at night (mountain 112, moon 113).
01 and 102 are displayed. Therefore, when real-time world images supplied from the same camera device 50 are combined regardless of the time zone, FIG.
As shown in (c), it is possible to generate a composite video that is a landscape with a different atmosphere. Although not shown, the same content may be transferred to another camera device 50.
When synthesized with the real-time world image supplied from the, a synthesized image with a different background can be generated.

As described with reference to FIG. 20, as a processing method for synthesizing the recorded video and the real-time world video, a frame of the recorded video and the frame of the real-time world video may be simply synthesized. A synthesis method using a key signal such as a (Chroma-key) method may be employed. In this case, as the recorded video, the background may be composed of a blue screen assuming that the video is synthesized in advance, and the real-time world video may be synthesized as the background. When the recorded video is a normal video, for example, a video portion corresponding to the character may be cut out, and the cut out portion may be combined with a real-time world video. In this case, a continuous frame of the recorded video data is compared, and a portion with a large change is synthesized with a real-time world image with a small change portion as a background. Such a combining method is shown in FIG.
Expanding the composite identification information shown in (1), for example, "0" ... no composite "1" ... simple composite "2" ... composite using chroma key method "3" ... cutout is used As the combination, the combination process may be performed based on the combination identification information.

FIG. 20 shows an example in which the recorded video is combined with the real-time world video captured by one camera device 50.
May be combined with the real-time world image captured in the step (a). In this case, the synthesizing unit 30 includes a frame memory for a recording video and a frame memory corresponding to a plurality of real-time world videos, and selectively outputs each frame data at a timing corresponding to the recording video as described in FIG. In this case, the output video data can be formed. Further, in this case, even without using a frame memory, output video data can be formed by switching frame data of a recorded video and frame data of a real-time world video on a data stream.

As described above, since the content reproduced from the disc 90 and the real-time world image captured by the camera device 50 are synthesized, the background of the content can be composed of the real-time world image. become. Therefore, it becomes possible to change the atmosphere of the same content every time the real-time world image is viewed. Also, as the content recorded on the disc 90, the background video can be omitted in consideration of synthesizing the real-time world video from the camera device 50,
The storage capacity of the disk 90 can be used efficiently.

<B> Second Embodiment In the flowchart shown in FIG. 15 as the first embodiment, the disk drive 80
An example has been described in which the server 60 is accessed and the address table is downloaded each time the server is loaded. However, if the address table once received from the server device is stored, the number of downloads of the address table can be reduced.

That is, in the disk drive device 80,
The address table downloaded from the server device 60 is stored in the RAM 41 or the flash memory 46 in association with the disk ID, and the next time the content of the same disk is reproduced, the address table is stored based on the address table stored in the RAM 41 or the like. Alternatively, an access process to the camera device may be performed. When the disk drive device 80 considers holding the address table for a relatively long time, in practice, the volatile RAM 4
Instead of 1, a method of storing the data in a nonvolatile memory such as the flash memory 46 or writing an address table on the disk 90 is preferable.

The processing steps in this case will be described with reference to the flowchart of FIG. In each of the steps shown in FIG. 23, the processing steps denoted by the same step numbers as those in FIG. FIG.
As shown in FIG. 8, when it is determined in step S005 that the loaded disk 90 is a camera-linked disk, the disk I read from the TOC of the disk 90 is read.
Based on D, the address table corresponding to the disk ID is searched (S030). That is, as described above, in the disk drive device 80, the flash memory 4
For example, a storage area of the address table is prepared as 6 and the downloaded address table is stored in association with the disk ID. Step S030
Then, in the stored address table, the address table corresponding to the current disk is searched using the disk ID.

According to the current disk 90 (disk ID), it was downloaded from the server device 60 in the past,
When the stored address table is obtained, the processing steps after step S011 may be executed based on the searched address table, as in the case of FIG.

The address table corresponding to the loaded disc 90 may not be extracted by the search in step S030. For example, the disk 90
Is the first time the disk drive 80 is loaded into the disk drive device 80. Although not shown in the flowchart of FIG. 23, if the address table is not obtained by the search in step S030, the address table is downloaded from the server device 60 as in the first embodiment. Become. That is, step S0 in FIG.
What is necessary is just to proceed to processing after 06.

As described above, the address table can be stored in the disk drive device 80, but the address table recorded in the server device 60 may be updated as necessary. Can be
In response to this, the address table stored in the disk drive device 80 also needs to be updated. For this purpose, in the disk drive device 80, for example, when the disk 90 is loaded, the address table update processing may be performed based on the update status of the address table in the server device 60. When considering such an update of the address table, both the disk drive device 80 and the server device 60 manage the address table in association with the disk ID, the camera address, and the update date and time information. Is done.

FIG. 24 is a flowchart for explaining an example of processing steps executed by the system controller 10 when updating the address table in the disk drive device 80. The updating process described in the flowchart of FIG. 24 is, for example, executed when the disc 90 is loaded, and the same processing steps as those in FIG. 15 are denoted by the same reference numerals.

When the data communication with the server device 60 is started and the disk ID is transmitted through the processing steps from step S001 to step S008, the disk I
It is determined whether or not the update date and time information of the address table transmitted from the server device 60 has been received in response to the transmission of D (S040). If it is determined that the update date and time information has been received, an address table corresponding to the disk ID is searched in the flash memory 46 or the like inside the disk drive device 80 (S041). As a result, the update date and time information of the address table recorded in the flash memory 46 or the like is detected.

Further, the received update date / time information is compared with the retrieved update date / time information (S042). If it is determined that the received update date / time information is a new date, a request for transmitting the address table to the server device 60 is issued. Yes (S04
3). When the transmission of the address table is requested, it is determined whether or not the address table transmitted from the server device 60 has been received in response to the transmission (S044). The address table recorded in the flash memory 46 or the like is updated (S045). Then, the pointer is initialized for the updated address table (S01).
1), camera connection processing (S012, S013, S01)
4, S015, S016, S017). If it is determined in step S042 that the received update date / time information is not a new date, the pointer is initialized in the address table searched from the flash memory 46 or the like in step S041 (S011), and the camera connection is established. Move on to processing.

As described above, by updating the address table as a part of the initial processing when a disc is loaded, for example, the camera connection processing can be performed based on the camera address indicated in the latest address table. Will be able to

In FIG. 24, an example in which the address table is updated as a part of the initial processing when the disc 90 is loaded has been described. However, in an environment where the disk drive device 80 and the server device 60 can always communicate with each other, the update process may be performed as needed. In this case, it is sufficient to compare the update date and time information with all the address tables recorded in the flash memory 46 or the like, and to always store the latest address table. Thereby, for example, when the processing steps of the flowchart shown in FIG. 23 are executed, the camera connection processing can be performed based on the latest address table.

FIG. 25 is a flowchart for explaining an example of processing steps executed by the control unit 63 in the server device 60 when the disk drive device 80 is enabled to execute the address table updating process as shown in FIG. It is. The same processing steps as in FIG. 17 are denoted by the same reference numerals. When the server device 60 receives the connection request from the disk drive device 80 and determines that the transmitted disk ID has been detected (S101 to S10).
2) Transmit the update date and time information of the address table corresponding to the disk ID (S111). As a result, the disk drive device 80 performs step S0 shown in FIG.
The processing steps indicated by reference numeral 42 are executed. And
Based on the transmission of the update date / time information, it is determined whether an address table update request has been received (S112). If it is determined that a transmission request has been received, the address table corresponding to the disk ID detected in step S102 is updated. Transmission is performed (S103).

As described above, the server device 60 can transmit the latest address table to the disk drive device 80. Therefore, by updating the address table of the server device 60, the disk drive device 80 capable of performing data communication with the server device 60 via the communication line 110 can obtain the latest address table.

<C> Third Embodiment In the third embodiment, a real-time world image in a time zone according to the content of the content reproduced by the disk drive device 80 is obtained.

As a real-time world image corresponding to the content, for example, if it is considered that a morning landscape is preferable,
When content plays during the day (morning, afternoon,
Regardless of whether it is midnight or the like, it is desirable to combine the morning scenery. Therefore, the address table may be configured so that a camera to be connected can be selected in consideration of a time difference, for example, in accordance with a time zone in which reproduction is performed.

FIG. 26 is an example of an address table showing camera addresses corresponding to the time zone (reproduction time zone) in which the content is reproduced. For example, based on this address table, the disk drive 8
Regardless of the playback time zone in which the content is played back at 0, a real-time world image as a morning scene (morning scene) that matches the content can be obtained. FIG.
In the address table shown in FIG. 5, camera addresses are shown for each reproduction time zone on the disk drive device 80 side, such as morning, afternoon, and midnight. Note that three camera addresses are shown in one playback time zone.
This is because the same scenery can be imaged by at least three camera devices 50 in consideration of a failure or the like, as in the case described with reference to FIG.

The camera addresses # 1, # 2, and # 3 indicate addresses to be accessed when the playback time zone in the disk drive 80 is in the morning. That is, it is the address of the camera device 50 installed in the place where the disk drive device 80 is in the morning when it is in the morning. For example, the camera address of the camera device 50 arranged in an area where there is almost no time difference from the area where the content is reproduced is shown. The camera addresses # 4, # 5, and # 6 correspond to the camera device 50 located in the region or country where the morning time zone is set when the playback time zone on the disk drive device 80 is in the afternoon. An address, that is, an address accessed in the afternoon to obtain a morning scenery is shown. Further, the camera addresses # 7, # 8, and # 9 indicate that the camera device 50 located in the region or country where the morning time zone is set when the playback time zone on the disk drive device 80 is midnight.
, That is, the address accessed to obtain the morning scenery in the late night time zone.

When the disk drive 80 downloads such an address table and performs camera connection processing, the camera address pointer is set based on the current time measured by the timer 37, for example. Just do it. Therefore, the process transition in this case is as shown in the flowchart of FIG. Similar to the flowchart shown in FIG. 15, after the disc is loaded, the processing steps shown in steps S001 to S010 are performed. In this example, in step S010, the address table shown in FIG. 26 is read. Then, the current time measured by the timer 37 is determined as the time at which the content is reproduced (S701). If it is determined that the current time zone is in the morning, as the pointer initialization processing, the index pointer is set to “1”, the camera address pointer is set to “1”, and the maximum value of the camera address pointer is set to “3”. "(S702), and the process proceeds to step S012. If it is determined in step S701 that the current time is afternoon, the index pointer is set to "1", the camera address pointer is set to "4", and the maximum value of the camera address pointer is set to "6". (S703). further,
If it is determined in step S701 that the current time is midnight, initialization is performed by setting the index pointer to "1" and the camera address pointer to "7", and further sets the maximum value of the camera address pointer to "9" ( S70
4).

Thus, regardless of the playback time zone, that is, the time zone in which the content is to be played back on the disk drive device 80 side, it is possible to obtain a real-time world image as, for example, a morning scene corresponding to the content. Become. That is, according to the processing in steps S012 to S016, if the current time (reproduction time zone) in the disk drive device 80 is in the morning, the camera address pointer is set to “1”.
To “3”, a real-time world image of the morning scenery is obtained. When the current time (reproduction time zone) in the disk drive device 80 is in the afternoon, the camera address pointer is set to any one of “4” to “6”. can get. Further, when the current time (reproduction time zone) in the disk drive device 80 is midnight, the camera address pointer is set to any one of "7" to "9". Is obtained. Note that, of course, this example is a case where the content of the content itself is set so as to require the synthesis of a real-time world image as a landscape in the morning. When the content itself is created in consideration of, for example, the synthesis of a real-time world video at midnight, the address table described above stores the actual time at midnight irrespective of the current time (reproduction time zone) in the disk drive device 80. It is generated so that the address of the camera device 50 from which the time world video is obtained can be obtained.

FIGS. 26 and 27 illustrate an example in which camera addresses corresponding to the playback time zone on the disk drive device 80, for example, in the morning, afternoon, and late at night, are managed in the same address table. However, an address table corresponding to each reproduction time zone may be individually managed. In this case, in the server device 60, address tables corresponding to, for example, morning, afternoon, and midnight reproduction time zones are individually formed and stored. Then, the disk drive device 80 sends the disk ID together with the connection request.
And the current time information measured by the timer 37 is transmitted to the server device 60. Thereby, the server device 6
In the case of 0, the address table is selected and transmitted based on the disk ID and the current time information, so that the disk drive device 80 can obtain the address table corresponding to the current time (reproduction time zone). However, if the server device 60 knows the installation position (country / region) of the disk drive device 80 and the server device 60 can determine the current time on the disk drive device 80 in consideration of the time difference, It is not necessary for the disk drive device 80 to transmit the current time information to the server device 60.

Note that other examples of the configuration of the address table are also conceivable. In the above example, a real-time world image in a time zone corresponding to the content of the content is obtained. In other words, for example, when the morning scenery is appropriate as the content of the content, a real-time world image as the morning scenery is always obtained regardless of the content playback time zone. Conversely, it is conceivable to obtain a real-time world image in the time (reproduction time zone) on the disk drive device 80 side or the time zone desired by the user, regardless of the content content. That is, in the address table of FIG. 26, different camera address pointers can be set for the playback time zone of the disk drive device 80 according to morning / afternoon / midnight. Time zone)
An address table in which camera addresses are set separately in the morning / afternoon / midnight is also conceivable. In this way, the scenery according to the current time on the disk drive device 80 side, the scenery in the time zone always shifted from the current time, or the scenery in the time zone desired by the user can be obtained as the real-time world image. Will be able to However, when the address table is divided into morning / afternoon / midnight as a local time zone, the address table needs to be constantly updated as time progresses.

Further, similarly to the above example, when real-time world video in a time zone corresponding to the content of the content is to be obtained, the region where the content is provided (the area of the disk drive device 80 where the content is reproduced). If the installation position (country of sale, etc.) is a wide area with a time difference, an address table corresponding to the installation position of the disk drive device 80 is required. Alternatively, as described above, the address table based on the local time at which the camera device 50 is installed is generated, and information indicating the time zone of the video requested by the content is recorded on the disc 90 or the like corresponding to the content. Need to be Then
It is possible to select the camera device 50 that is capturing the scenery of the time zone required by the content from the address table and establish communication.

It is also conceivable to use a regional code. In the disk drive device 80 and the disk 90,
An area code (regional code) is set for each area used for shipment. This area code is set, for example, to limit the reproduction of the disc 90. When the area codes of both the disc drive device 80 and the disc 90 match, the reproduction is permitted.
By using this region code, it is also possible to specify a region where the reproduction of the disc 90 is performed, and to select a camera address suitable for the region. In this case, the address table may be configured such that the classification such as morning, afternoon, and midnight shown in FIG. 26 is made to correspond to each area code. That is, in the disk drive device 80, the disk I
When the address table downloaded based on D is used, by setting the pointer based on the area code, it becomes possible to select a different camera address for each area for the same scene. Also, in this case, even when playing the same scene with the same content,
Real-time world images (for example, landscapes related to the region) that differ depending on the region can be synthesized, and it is possible to realize an enjoyment method corresponding to each region. When specifying a more detailed area than the area indicated by the area code, area information that can indicate a detailed area may be set as lower order information of the area code.

<D> Fourth Embodiment In the fourth embodiment, the operation of the camera device can be controlled according to the content to be reproduced. When the disk drive device 80 receives the real-time world video imaged by the camera device 50, the disk drive device 80 controls the camera device 50, such as zooming, or arranges the camera device 50 on a camera platform. By controlling the camera platform, it becomes possible to cause the camera device 50 to capture a real-time world image in correspondence with a certain content.

In this case, the configurations of the camera device 50 and the camera platform are shown in FIG. As shown in FIG. 28, the configuration of the camera device 50 is substantially the same as the configuration shown in FIG. 3, but is arranged on a camera platform. The control unit 57 is configured as shown in FIG.
Performs the video signal processing related to the imaging described in
Based on the imaging control information (lens system control information and pan head control information) received in step (1), it is possible to perform drive control such as zoom drive of the lens unit 51 and drive control such as pan and tilt of the pan head. Have been.

It is assumed that the content recorded on the disk 90 includes imaging control information. The imaging control information is superimposed on the recording video signal in a frame unit, for example, similarly to the combined identification information described with reference to FIG. The extracted imaging control information (lens system control information and pan head control information) is transmitted to the communication unit 3
1 is transmitted to the camera device 50. With the lens system control information as the imaging control information transmitted in this way, the control unit 57 can perform lens driving such as zooming on the lens system 51, for example. The control unit 57 is supplied from the transmission unit 56.
Pan head control information relating to the angle of the camera device 50 can be supplied to the pan head 70.

The camera device 50 is arranged on a camera platform 70. For example, the camera device 5 that is disposed
A drive unit 71 for changing the imaging angle of 0 and a control unit 72 for controlling the drive of the drive unit 71 are provided. The control unit 72 is, for example, the control unit 57 of the camera device 50.
The driving of the drive unit 71 is controlled based on the imaging control information supplied from. As a result, the imaging angle of the camera device 50 can be changed (that is, panned or tilted), for example, in an upward direction, a downward direction, a rightward direction, a leftward direction, or the like. Note that by controlling the communication unit 31 so that the lens system control information and the camera platform control information are separately transmitted from the disk drive device 80, the camera platform control information is directly transmitted to the camera platform 7.
It is also possible to send to 0.

FIG. 29 is a schematic diagram for explaining the imaging control information superimposed on each frame of the recording video data supplied from the video data decoding unit 29 to the synthesizing unit 30, for example. In this figure, for example, in frame n + 2, zoom instruction information as lens system control information together with composite identification information,
An example is shown in which right direction instruction information is superimposed as pan head control information. Therefore, the zoom instruction information and the rightward instruction information are extracted by decoding the frame n + 2 in the video data decoding unit 29 and transmitted by the communication unit 31. As a result, the camera device 50 performs zoom drive, and the pan head 70 performs drive control to turn the imaging angle of the camera device 50 rightward. Therefore, as the real-time world video supplied to the disk drive device 80, the scenery in the right direction is enlarged and captured with respect to the video before the drive control is performed. That is, by setting the imaging control information in association with the content, the real-time world video imaged by the same camera device 50 can be specialized for the content.

Note that the combined identification information may be managed in an address table. In this case, as shown in FIG. 30, for example, the combined identification information may be recorded in association with the camera address information. As a result, the disk drive device 80 can select the combining method for each scene corresponding to the index information, for example. Similarly, it is also possible to manage the imaging control information in the address table. Again,
What is necessary is just to record the lens system control information and the camera platform control information in correspondence with the camera address information. When reproducing the content, the disk drive device 80 transmits zoom control, angle control, and the like for each scene by transmitting lens system control information and camera platform control information corresponding to the scene to be reproduced to the camera device 50. Will be able to

Further, the camera address and the imaging control information may be managed in the lead-in area of the disk 90. As a result, the camera address and the imaging control information can be associated with the content recorded on the disk 90, and the camera device can be selected for each content. Furthermore, by associating the imaging control information with the division unit obtained by dividing the content for each time, different real-time world images based on the imaging control information can be obtained from the same camera device as the content is reproduced. Become like

FIG. 31 is a diagram for explaining an example in which camera addresses and imaging control information are managed in the lead-in area of the disk 90. In the index information, imaging control information corresponding to a segment unit is recorded together with a start time and an end time which are each segment information (program, chapter, scene). Then, a camera address corresponding to the content is recorded as link information, so that a camera device that performs data communication can be indicated to the disk drive device 80. Therefore, in the disk drive device 80, when the disk 90 on which the lead-in area shown in FIG. 31 is formed is loaded, data communication with the camera device 50 is started based on the camera address, and reproduction of the content is executed. I do. Then, for example, if scene # 1 is being played, zoom (enlarge)
If the scene # 2 is being reproduced, zoom (reduction) is performed, and if the scene # 3 is being reproduced, the imaging control information corresponding to each scene is transmitted to the camera device 50, such as tilt (up). That is, the disk drive device 8
A value of 0 allows the imaging control information corresponding to the scene to be sequentially transmitted to the camera device 50 with the lapse of time of the content reproduction.

FIG. 32 is a flowchart for explaining an example of processing steps performed by the system controller 10 of the disk drive device 80 when the disk 90 having the lead-in area shown in FIG. 31 is loaded. Processing steps denoted by the same step numbers as those in FIG. 15 are the same processing. That is, when the disc 90 is loaded, disc identification, reading of TOC data, and detection of a camera link flag are performed (S001 to S004). When it is determined that the loaded disk 90 is a camera-linked disk (S005), a camera address is detected from the lead-in area (S801), and a data communication process with the camera device 50 is started based on the camera address. (S802). As a result, real-time world video data is supplied from the camera device 50 to the disk drive device 80. Further, the reproduction of the content is started (S
803), the imaging control information corresponding to the scene being reproduced is transmitted to the camera device 50 performing the data communication (S804). If it is determined in step S005 that the loaded disk 90 is not a camera-linked disk, for example, the content is simply reproduced (S80).
5).

By performing such processing, the disk drive device 80 performs data communication with the camera device 50 corresponding to the content recorded on the loaded disk 90 to obtain a real-time world image. become able to. Then, various imaging controls can be executed by the camera device 50 based on the imaging control information, so that it is possible to obtain a different real-time world image for each scene, for example. In other words, referring to FIG. 6, when a city image is used as a background of a certain content, FIG.
The camera address of the camera device 50a is recorded in the lead-in area shown in FIG. Further, by recording the imaging control information as needed, it becomes possible to enlarge the image of a city, which is a real-time world image, or change the imaging angle for each scene, for example. In other words, the disk drive device 80 can obtain different images, for example, for each scene from the same camera device 50a during the reproduction of the content. When two or more different contents are recorded on one disc 90, for example, data communication with a different camera device 50 for each content may be performed. In this case, for example, a camera address corresponding to each content may be recorded in the lead-in area.

<E> Fifth Embodiment In a fifth embodiment, an address table is stored in a disk. In each of the embodiments described above, an example is described in which the server device 60 manages an address table, which is link information with the camera device 50, and the disk drive device 80 downloads the address table as needed. Then, the address table is managed by the disk 90. That is, the content table and the address table corresponding to the content are recorded in the disc 90 in advance. Disk drive device 8
No. 0 communicates with the camera device 50 based on the address table read from the disk 90, receives the supply of the real-time world video, combines this with the content data reproduced from the disk 90, and outputs it. In this case, in terms of processing related to the address table, the server device 60
Can be unnecessary. However, the server device 60 is necessary in consideration of the update described later.

In this case, the address table shown in FIG. 5 or FIG. 30 is recorded in, for example, the TOC of the lead-in area of the disk 90. Then, in the disk drive device 80, when shifting to the process of playing the content after the disk 90 is loaded, the address table may be read from the TOC and the camera connection process may be performed. The processing steps in this case are as shown in the flowchart of FIG. 33, for example. As can be seen from a comparison between the processing steps shown in the flowchart shown in this figure and the processing steps shown in the flowchart shown in FIG. 15, step S901 is different. That is, if it is determined in step S005 that the disc is a camera-linked disc, the address table recorded on the disc 90 is read (S90).
1) Initialize the index pointer and the camera address pointer (S011). Subsequent processing is the same as in FIG.

As described above, by recording the address table on the disk 90, it is not necessary to perform the communication processing (S006 to S010) with the server device 60 shown in FIG. This can reduce the processing load,
It is possible to quickly shift to the camera connection processing.

Other possible locations for recording the address table on the disk 90 are as follows. As an optical disk, a so-called partial ROM disk in which a storage area formed on one disk is divided into a read-only ROM area and a rewritable RAM area is known. Using such a partial ROM disk, for example, the contents that do not need to be rewritten
Area, and the address table is recorded in the RAM area. As a result, similar to the processing steps described in the flowchart of FIG. 31, the camera connection processing can be performed without the communication processing with the server device 60.

Further, by updating the address table in the RAM area of the disk 90, the address table can be updated. In this case, the address table is recorded in the RAM area together with the update date and time information. Then, similarly to the process described in the flowchart of FIG. 24, the RAM area of the disk 90 is compared with the update date / time information recorded in the server device 60, and when it is determined that the update date / time of the server device 60 is newer, Downloads the address table from the server device 60 and
Update the address table recorded in the RAM area. By performing such update processing, the disk 90
Will be able to record the latest address table. As a result, the disk 90 can indicate the latest address table to the loaded disk drive device 80.

By the way, in the disk drive device 80 shown in FIG. 2, when data is recorded as an address table on the disk 90, first, the received address table is subjected to error correction processing in the error correction unit 32,
After that, write processing (write pulse) is generated by performing an encoding process according to the recording data format on the disk 90. Then, the write data may be supplied to the laser driver 18 and the laser driver 18 may be controlled to output a laser power at a recording level. The laser light generated in this manner is irradiated onto the recording surface of the disk 90 via the objective lens 2, so that an address table can be recorded on the disk 90.

<F> Sixth Embodiment In a sixth embodiment, a disk drive communicates with a camera device based on a camera address input or specified by a user to supply a real-time world image. This is combined with the content data reproduced from the disc and output. That is, in each of the above embodiments, an example is described in which the address of the camera to be connected is managed by the address table. However, here, the user operates the operation unit 38 provided in the disk drive device 80 to allow the user to operate. It is possible to select a real-time world image arbitrarily. In this case, the server device 60 may be unnecessary. Further, the address table is not used, or is used in parallel with the user operation of this embodiment.

For input of the camera address, the user may input a value as a camera address using the operation unit 38 or the like, or a menu for displaying a real-time world image as a guide. A video signal may be generated and supplied to a monitor device. As described above, by enabling the user to select a real-time world image, the user can enjoy the content by arranging the image. In other words, it becomes possible to appreciate the background or the like of a different real-time world image every time reproduction is performed. When the user can select a real-time world image, the selection history is managed, and a camera address with a high selection frequency is preferentially selected to execute the camera connection process. Good. The selection history information may be recorded in the flash memory 46 or the like of the disk drive device 80 in association with, for example, a disk ID or the like, or may be recorded on the disk 90. This allows
Based on the selection history information, it is possible to automatically select a real-time world video that is selected by the user and that is frequently selected.

<G> Seventh Embodiment The first to third embodiments are basically the same as the disk I.
D based on the address table corresponding to D
The example of accessing 0 has been described. That is, an address table is prepared corresponding to the disk 90.
In the seventh embodiment, it is assumed that the server device 60 has an address table for keyword management, and that keywords are recorded on the disc 90 corresponding to contents. Then, when reproducing the disc 90, the disk drive device 80 transmits a keyword corresponding to the content to the server device 60, and receives an address table corresponding to the keyword from the server device 60. The disk drive device 80 communicates with the camera device 50 based on the address table, and receives the supply of the real-time world image. This is combined with the recorded video of the content reproduced from the disc 90 and output. That is, a keyword is used as information for specifying the address table, instead of the disk ID.

FIG. 36 shows a state in which a keyword is recorded in the lead-in area of the disc 90 in correspondence with the index information of the content (for example, an index corresponding to the content or a scene obtained by dividing the content). . That is, in the index information, information such as "sea" and "mountain" are recorded as keywords corresponding to the segment units, together with the start time and the end time as each segment information (program, chapter, scene).
The capacity information, the number of layers, the track path direction, the recording start / end position information, the camera interlocking identification flag, and the server device address are described in FIG. 8 described in the first embodiment.
Is the same as

On the other hand, the database 62 of the server device 60
Stores an address table as shown in FIG. In this address table, keywords such as "sea", "city", "mountain", "town" ...
The camera address is stored. For example, in unit number 1 forming the address table, camera addresses # 1, # 2, and # 3 corresponding to the keyword "sea" are stored. That is, the address of the camera device 50 installed on the coast or the like and imaging the seascape. The reason why a plurality of camera addresses # 1, # 2, and # 3 are stored is to cope with a busy state or a failure as described in the above embodiments.

In this case, the processing of the disk drive device 80 is as shown in FIG. The processing example of FIG. 34 is based on the processing of FIG. 15, and the same processing steps are denoted by the same step numbers (S001 to S0).
07, S009 to S018). In this case, step S0
After a communication request is made to the server device 60 at 07, a keyword recorded on the disk 90 as shown in FIG. 36 is transmitted as step S901. The processing after receiving the address table is the same as in FIG.

On the other hand, the controller 63 in the server device 60
Is as shown in FIG. In step S101, the server device 60 is in a standby state for determining whether a connection request transmitted from the disk drive device 80 via the communication line 110 has been received. If the control unit 63 determines that a connection request has been received in this standby state,
A data communication process with the disk drive device 80 that has transmitted the connection request is started, and the disk drive device 80
It is determined whether or not the keyword transmitted from is received (S121). When determining that the keyword is detected, the control unit 63 searches the database 62 for an address table corresponding to the detected keyword (S12).
2). That is, as shown in FIG. 37, an address table unit with a matching keyword is searched.

After the search in step S122, the communication unit 61 is controlled to transmit the selected address table unit to the disk drive device 80 that has received the connection request (S104). This is the return process to the disk drive device 80 that has received the connection request. Then, after transmitting the address table, the communication process with the disk drive device 80 that has received the connection request is terminated. Thus, in the disk drive device 80, the address table can be obtained as one or a plurality of address table units corresponding to the keyword.

Therefore, according to the content (keyword) of a scene or the like reproduced from the disc 90, data communication can be performed with the corresponding camera device 50, and a real-time world image can be received. By such a process, a background image or the like suitable for the content of a scene or the like specified by the keyword is obtained.
This makes it possible to synthesize and output the recorded video.

Although the keywords are recorded in the disc 90 in advance, the keywords on the disc 90 may be non-rewritable information or may be rewritable. In the case of rewritable information, the user can obtain a desired background image by rewriting the information with an arbitrary keyword. Alternatively, only the recording area (or management structure) of the keyword may be prepared on the disc 90, so that the user can arbitrarily set the keyword.
Further, the keyword may not be recorded on the disk 90 but may be stored in the RAM 41 or the flash memory 46. At this time, the keyword may be stored in association with the disc ID, or the user may set a keyword irrespective of the content of the disc 90.

<H> Eighth Embodiment In the first, second, third, fifth, and seventh embodiments,
The disk drive 80 takes in the address table in some form and communicates with the camera device 50. The eighth embodiment is an example in which the server device 60 manages communication between the disk drive device 80 and the camera device based on the address table without the disk drive device 80 directly handling the address table. It is.

That is, first, the address table is stored in the database 62 of the server device 60. The disk drive device 80 stores the disk I of the disk 90 to be reproduced.
D is transmitted to the server device 60. The server device 60 searches the address table from the disk ID and the like, and manages the communication between the corresponding camera device 50 and the disk drive device 80. That is, in this example, the address table itself is not supplied to the disk drive device 80.

In this case, the processing of the disk drive device 80 is as shown in FIG. In FIG. 38, the same processing steps as those in FIG. 15 are denoted by the same step numbers (S001 to S008, S018). In this case, the processing up to step S008, that is, the processing from sending a communication request to the server device 60 and transmitting the disk ID is the same as that in FIG. Thereafter, in step S1001, the system controller 10 waits for communication with the camera device 50 to be established. And the camera device 50
When the communication with is established and the real-time world video is received, the content reproduction is started in step S018. That is, the disk drive device 80 does not perform control for communication with the camera device 50, but simply waits for establishment of communication with the camera device 50 and transmission of a real-time world image.

On the other hand, the control unit 63 in the server device 60
Is as shown in FIG. In step S131, the server device 60 is in a standby state for determining whether a connection request transmitted from the disk drive device 80 via the communication line 110 has been received. If the control unit 63 determines that a connection request has been received in this standby state,
A data communication process with the disk drive device 80 that has transmitted the connection request is started, and the disk drive device 80
It is determined whether or not the disk ID transmitted from is received (S132). When determining that the disk ID has been detected, the control unit 63 subsequently acquires the current time (S13).
3). For example, a clock unit is provided in the server device 60, and the current time is acquired from the clock unit. The current time information may be received from the disk drive device 80. Subsequently, an address table is searched from the database 62 based on the received disk ID and the acquired current time (S134).

In the case of the address table configuration shown in FIG. 5 described in the first embodiment, a search can be performed only from the disk ID. As described in the third embodiment, when the contents of the address table corresponding to the disk ID further correspond to the time (time zone), the address table (camera address) is obtained from the disk ID and the current time. Can be searched. Further, the database 62 stores the IP addresses of the camera devices 50 around the world, time and weather information of installation locations, and connection statuses of the devices, and if these are updated in real time, optimal real time It is also possible to determine the camera device 50 that can acquire a world image and determine whether connection is possible. In this case, the search method can be an existing method such as a method like a Web search site or a dictionary search. Further, the search target need not necessarily be the database managed by the server device 60.

When the control unit 63 searches the corresponding address table and obtains the camera address of the camera device 50 to communicate with, it controls the communication unit 61 and transmits a connection request to the camera device 50 of the camera address. Let it. However, this connection request is a connection request from the disk drive device 80.

The camera device 50 performs the processing of FIG. 18 in the same manner as in the first embodiment, and performs communication processing in response to a connection request from the disk drive device 80 transmitted from the server device 60. . Thus, the real-time world image is transmitted to the disk drive device 80 as described above. In the disk drive device 80, the real-time world video data transmitted from the camera device 50 is combined with the recorded video data reproduced from the disk 90 and output by the processing in FIG.

In this example, the connectable camera device 50 can be determined by searching the database.
In a case where information as to whether or not each camera device 50 can communicate is not included in the database, the server device 60
It is possible to execute the pointer setting process for determining the communicable camera device 50, that is, the process described as being performed on the disk drive device 80 side in steps S011 to S016 in FIG. 15, and then perform the connection request in step S135. Conceivable.

As described above, in the case of this embodiment, the server device 60 executes the communication control between the disk drive device 80 and the camera device 50, and the address table is held only by the server device 60. It will be good. This is because the server device 60 can centrally manage the address table and the disk drive device 8
0 has the advantage that the communication control processing load with the camera device 50 and the need to receive or update the address table are not required.

The communication between the camera device 50 and the disk drive device 80, that is, the transmission of the real-time world video data may be performed by the camera device 50 directly transmitting the data to the disk drive device 80 or by the camera device 50 once. The information may be transmitted to the server device 60 and transmitted to the disk drive device 80 via the server device 60.
As a modified example, when the server device 60 determines the camera device 50 that performs communication, the server device 60 transmits the camera address to the disk drive device 80, and the disk drive device 8
0 itself may establish communication with the camera device 50.

Further, based on the processing of the first embodiment, in the third and seventh embodiments, acquisition of a real-time world image according to the reproduction time zone, real-time world Although the example of acquiring a video has been described, an example of acquiring a real-time world video according to a reproduction time zone and acquiring a real-time world video according to a keyword based on the processing of the eighth embodiment are described. Is of course also possible.

<I> Ninth Embodiment A ninth embodiment is a processing mode of the eighth embodiment, that is, a mode in which the server device 60 manages communication between the disk drive device 80 and the camera device 50. , A real-time world video of the weather according to the content of the content reproduced by the disk drive device 80 can be obtained.

[0160] As a real-time world image corresponding to a content scene, for example, if it is considered that a fine landscape is preferable, a real-time world image is obtained from the camera device 50 installed in a currently sunny area. It is desirable.
For a scene in which a person has an umbrella as a character to be reproduced, for example, a camera device 50 installed in a currently rainy area so that the background image is a rainy landscape.
It is desirable to obtain a real-time world video from. Therefore, the address table may be configured so that the camera device 50 in an appropriate weather area can be selected according to the content (scene or the like) to be reproduced. Also,
The disk 90 only needs to record weather information corresponding to a scene or the like.

FIG. 42 shows a state where the index information of the content (for example, the index corresponding to the content or the scene obtained by dividing the content) is recorded in the lead-in area of the disc 90 in correspondence with the weather information. I have. That is, in the index information, information such as “sunny”, “cloudy”, and “rain” are recorded as weather information corresponding to the segment unit, together with the start time and the end time as each segment information (program, chapter, scene). ing. Note that the capacity information, the number of layers, the track path direction,
The recording start / end position information, camera interworking identification flag, server device address, and disk ID are the same as those in FIG. 8 described in the first embodiment.

FIG. 43 is an example of an address table in which camera addresses are indicated according to the local weather. For example, based on this address table, it is possible to obtain a real-time world image which is a landscape of the weather according to the contents of the content (the weather information). FIG.
In the address table shown in (2), camera addresses are shown in accordance with the weather at the site (where the camera device 50 is installed). Note that three camera addresses are indicated in one weather, as in the case described with reference to FIG. 5, the same scenery can be imaged by at least three camera devices 50 in consideration of a failure or the like. It is because it is made possible.

The camera addresses # 1, # 2, and # 3 correspond to the camera devices 50 installed in the currently sunny area.
Is shown. Also, camera address #
4, # 5, and # 6 indicate addresses of the camera devices 50 installed in the currently cloudy area. Further, the camera addresses # 7, # 8, and # 9 indicate the addresses of the camera devices 50 installed in the area that is currently raining. This address table is updated in real time. That is, the server device 60 always collects the weather information of all over the world (the area where the camera device 50 is installed), and accordingly, the contents of the address table,
That is, the camera address is updated.

The processing of the disk drive 80 is shown in FIG.
become that way. In FIG. 40, the same process steps as those in FIG. 38 are denoted by the same step numbers (S0
01 to S007, S1001, and S018). In this case, when the system controller 10 makes a communication request to the server device 60 by the processing up to step S007, in step S1101, the system controller 10 transmits the weather information corresponding to each index information as shown in FIG. . Thereafter, in step S1001, the process waits for the communication with the camera device 50 to be established. When the communication with the camera device 50 is established and the real-time world image is received, the content is determined in step S018. Starting playback is the same as in FIG.

On the other hand, the control unit 63 in the server device 60
Is as shown in FIG. In step S131, the server device 60 is in a standby state for determining whether a connection request transmitted from the disk drive device 80 via the communication line 110 has been received. If the control unit 63 determines that a connection request has been received in this standby state,
A data communication process with the disk drive device 80 that has transmitted the connection request is started, and the disk drive device 80
It is determined whether or not the disk ID transmitted from is received (S132). When determining that the disk ID has been detected, the control unit 63 subsequently searches the database 62 for an address table based on the received disk ID (S140). That is, an address table having a structure as shown in FIG. 43 is searched.

Subsequently, based on the weather information received together with the disc ID, a camera address pointer is set according to the weather requested by the content (scene). First, the variable n indicating the index pointer is set to “1” (S
141). Thereby, for example, processing corresponding to the first index information (scene) # 1 in FIG. 42 is performed. In step S142, the content of the weather information of index information #n (that is, # 1) is determined. If the weather information corresponding to the index information (scene) # 1 is “clear”, the index pointer is set to “n”, ie, “1”, and the camera address pointer is set to “1” as pointer initialization processing. Then, the maximum value of the camera address pointer is set to "3" (S143), and step S146 is performed.
Proceed to. If it is determined in step S142 that the weather information is "cloudy", the index pointer is set to "n (= 1)", the camera address pointer is set to "4", and the maximum value of the camera address pointer is set to "4". 6 "
(S144). If it is determined in step S142 that the weather information is “rain”, initialization is performed by setting the index pointer to “n (= 1)” and the camera address pointer to “7”, and further setting the maximum value of the camera address pointer to It is set to "9" (S145).

As a result, a real-time world image of the weather corresponding to the content scene # 1 can be obtained. That is, the processing of steps S146 to S149 is the same as that of FIG.
7 is basically the same as the processing described as steps S012 to S014, and when the weather information is fine,
Since the camera address pointer is set to any one of "1" to "3", communication between the camera device 50 and the disk drive device 80 installed in a sunny area is performed. This example is similar to the eighth embodiment, except that the server 6
0 performs communication management between the disk drive device 80 and the camera device 50, and FIG.
0 processing. Therefore, as step F149,
The server device 60 transmits a connection request from the disk drive device 80 to the camera device 50 at the camera address designated by the pointer. In response, the camera device 5
0 indicates that the real-time world image is transmitted to the disk drive device 80. When the weather information is cloudy, the camera address pointer is set to any one of “4” to “6”, so that the communication between the camera device 50 and the disk drive device 80 installed in the cloudy area is performed. Furthermore, if the weather information is rain, the camera address pointer will be "7" ~
Since any one of “9” is set, communication between the camera device 50 and the disk drive device 80 installed in the rainy area is performed.

In step S150, the variable n serving as the value of the index pointer is incremented, and the camera address pointer is initialized. Then, step S1
In 51, it is determined whether or not the table of the index pointer #n exists, that is, whether or not the processing corresponding to all scenes has been completed, and if not completed, the process returns to step S142. Therefore, next, the process corresponding to the second index information (scene) # 2 in FIG. 42 is performed. That is, similarly, in steps S142 to S154, the index pointer, the camera address pointer, and the maximum value of the camera address pointer are set based on the weather information.
In steps S149 to S149, the camera device 50 corresponding to the weather information of the index information #n (that is, # 2) is selected, and communication between the camera device 50 and the disk drive device 80 is established.

By the above processing, the real time world image in the designated weather state can be acquired for each scene to be reproduced by the disk drive device 80, and can be synthesized and output as a background image.

In the address table of the example shown in FIG. 43, the camera address is managed by the index pointer and the local weather matrix. However, the camera address may be managed only by the local weather. That is, in this example, the camera address is selected based on only the weather information designated as the weather requested by the content (or scene).

Although the address table of FIG. 43 has been described with an example in which camera addresses corresponding to each weather are managed by the same address table, the address tables corresponding to each weather may be individually managed. Good. In that case, the address table may be searched based on the weather information.

Further, although the weather information is recorded on the disc 90 for each scene (index information), one weather information may be recorded for the entire content or the entire disc. Furthermore, weather information recorded on the disc 90 in accordance with the content or the scene,
It is conceivable that the user can rewrite it. For example, if the camera address of each weather is stored for each index in the address table as shown in FIG. 43, even if the user arbitrarily rewrites the weather information (for example, changes “sunny” to “rain”), You can get a real-time world picture of the necessary weather accordingly.

Further, the weather information may not be recorded on the disk 90. For example, when the disk 90 is reproduced, the user may arbitrarily designate the weather by operating the operation unit 38 or the like, and the designated weather may be transmitted to the server device 60 as weather information. Then, a real-time world image in the weather specified by the user can be obtained.

In the above example, the processing for obtaining the real-time world image of the weather according to the contents of the contents is performed. Real-time world image of the weather according to the weather of the installation location). In this case, a function for detecting a weather condition such as a humidity sensor is prepared in the disk drive device 80, and the detected weather condition is used as weather information in the server device 60.
May be transmitted to the user. Alternatively, the server device 60 may be provided with a humidity sensor so that the weather condition can be detected.

By the way, the selection of the camera device 50 according to the weather is performed according to the processing of the first embodiment.
That is, the server device 60 transmits the address table to the disk drive device 80, and
Is basically applicable to a system operation mode in which a camera address is selected from an address table. Further, in the third embodiment, an example has been described in which a real-time world image in a time zone according to the content is obtained regardless of the current time on the disk drive device 80 side. The choice of this ninth
As in the case of the embodiment, the processing may be executed on the server device 60 side. That is, in the description of the third embodiment, in FIG. 27, in steps S701 to S016 as processing on the disk drive device 80 side, pointer setting for camera address selection according to the current time is performed. The processing is performed on the server device 60 side as in steps S142 to S151 of FIG. In this case, the server device 60 may receive the time information measured by the clock unit 37 from the disk drive device 80, or the server device 60 may be able to measure the current time of the disk drive device 80. I just need.

<J> Tenth Embodiment In the above-described first to ninth embodiments, the content reproduction device section is the disk drive device 80, and the content is reproduced from the disc 90. May be downloaded from a distribution server or the like. The tenth embodiment is an example in which a real-time world video is synthesized when a content downloaded by a playback device is played back.

FIG. 44 shows the system configuration. The same parts as those in FIG. in this case,
The content reproducing device 81 is, for example, a personal computer or a so-called MP3 player, and is connected to the content server 100 via a network (communication line 110).
It is assumed to be a device capable of downloading content data from the device.

[0178] The content reproducing apparatus 81 has at least the structure of a storage section, a communication section, a reproduction processing section, and a control section. The storage unit is, for example, a hard disk drive (HDD), a solid-state memory, or a portable medium.
Stores downloaded content data. The communication unit communicates with the content server 10 via the communication line 110.
0, perform data communication with the server device 60 and the camera device 50. The reproduction processing unit performs a synthesizing process on the content data stored in the storage unit with a real-time world video and outputs the result. The control unit controls the operation of each of these units.

The content server 100 transmits content data in response to a download request from the content reproducing device 81, for example. At this time, together with the content data, a content ID, a camera link identification flag, a server device address (address of the server device 60), and the like are also transmitted. The content reproducing device 81 stores these information together with the content data. The server device 60 holds and manages an address table and manages communication between the camera device 50 and the content reproduction device 81 in the same manner as in the above-described example. May be provided.

The process of the control unit of the content reproducing device 81 when reproducing the downloaded content data is as shown in FIG. When the user instructs to reproduce a certain content stored in the internal storage unit, the process advances from step S1201 to S1202,
The content ID is detected. Further, the camera-linked identification flag stored corresponding to the content ID is detected (S1203), and it is determined whether the content is camera-linked content (S1204). If the content is camera-linked content, the address of the server device 60 is read (S
1205), a communication request is made to the server device 60 (S1206). When the communication is established, the content ID is transmitted to the server device 60 (S120).
7).

Thereafter, in step S1208, content reproduction device 81 waits for communication with camera device 50 to be established. When communication with the camera device 50 is established and real-time world images are received,
In step S1209, content reproduction output is started.

On the other hand, in this case, the server device 60 may perform the processing of FIG. 39 described above. Ie, disk I
As an alternative to D, the address table is searched using the content ID, and the camera address of the camera device 50 to communicate with is obtained. Then, a connection request from the content reproduction device 81 is transmitted to the camera device 50 of the camera address.

The camera device 50 performs the processing of FIG. 18 in the same manner as in the first embodiment, and performs communication processing in response to the connection request from the disk drive device 80 transmitted from the server device 60. . As a result, the real-time world video is transmitted to the content reproduction device 81 as described above. The content reproducing device 81 combines the real-time world video data transmitted from the camera device 50 with the video data of the content reproduced from the storage unit and outputs the same by the same processing as in FIG.

As described above, the real-time world video can be synthesized and output not only for the content recorded and provided on the disk 90 but also for the content downloaded via the communication line 110. In addition, the above-mentioned second to ninth
The embodiments described above and the various modifications described in the description thereof can be applied to the playback of downloaded content.

<K> Application Examples Although various embodiments have been described above, more various application examples are conceivable as the present invention. The following is a brief description.

First, as an example of use of the above embodiment, for example, the disc drive device 80 is used as a home playback device, and the disc 90 is used to record contents such as guidance and advertisement in a supermarket or a showroom. Then, data communication can be performed with the camera device 50 that images the inside of a sales floor or a showroom of a supermarket. By distributing such discs to users at supermarkets and showrooms, users can view information and advertisements of supermarkets, which are regarded as contents in each home, and also provide real-time world images, such as sales floor conditions. Will be able to see.

Further, the car navigation device is used as a playback device (disk drive device), and navigation information such as a map is recorded as content on a recording medium such as a disk. Then, for example, by performing data communication with a camera device monitoring an expressway, it is possible to combine and display navigation information and a road situation as a real-time world image. Therefore, the user can grasp a desired condition of the highway while driving his own vehicle, and can select an efficient route based on the condition. In a car navigation device, for example, by linking it with a camera device monitoring a parking lot, it becomes possible to show the degree of congestion of a target parking lot as a real-time world image.

[0188] Further, a disk drive device (content reproducing device) can be applied as a game device. That is, when playing a disk (or download content) as so-called game software, a real-time world image is combined with a character background as a game image. In particular, by changing the camera device 50 to be communicated according to the progress of the game (the progress of the game stage) or the content of the stage, a background image corresponding to the progress of the game or the content can be obtained.

[0189] Further, the data content reproduced as a disc or download content may be text data or the like, and a real-time world image may be synthesized and output on the background. For example, an introduction sentence such as a region, a trip, or a country is set as text data, and at the time of reproducing the text data, a real-time world image is actually synthesized and output from the camera device 50 installed in the region / country where the introduction is made. This is very suitable.

Furthermore, by recording karaoke audio and subtitles as contents to be recorded on the recording medium, and using real-time world video supplied from the camera device as the background of the subtitles, the disk capacity can be reduced. And the cost of production of the background can be reduced.

Further, in the fourth embodiment, an example in which the disk drive device 80 controls the operation (zoom, pan, etc.) of the camera device 50 has been described. It is also conceivable that one camera device 50 can directly communicate with the camera 80 and the real-time world image captured by the camera device 50 is synthesized with the reproduced video. That is, the disk drive device 8
For 0, a dedicated camera device 50 that can communicate in any communication mode is provided, and the system is completed.
