2. Description of the Related Art With the recent improvement in computer processing technology, the field of application has been expanding more and more. Computer systems are widely used in various research institutions such as universities, offices of companies, and even ordinary households, and many daily tasks are implemented on computers.

For example, game machines that rely on computer processing have become widespread in arcades, ordinary homes, and the like. That is, the rules related to the game and the processing operation of the game are described in a computer processing language, and the program described in the computer processing language format is executed on a processor of a game machine (or a personal computer).
The execution results, that is, the scenes of the game and the progress of the game are displayed on a display screen.

[0005] Game software describing the game operation is generally a ROM (Read Only Memory).
y) It is supplied, that is, distributed on the market, in a form stored in a portable non-volatile recording medium such as a cartridge, a magnetic disk, or an optical disk, which is detachable from the game machine body and portable.

Further, a game system of a type in which a recording medium on which "game data" used during execution of specific game software is recorded is additionally purchased and the data is updated has already been put to practical use. This type of game data includes real-world data used for games that simulate phenomena or events in the real world.
Data.

For example, for a so-called baseball game, the team's performance and ranking in professional baseball, which is an event in the real world, or the performance of each player (for a fielder, batting average / scoring area batting average, batting average, number of home runs, etc.) By supplying real data such as the number of wins and losses, the ERA, the number of strikeouts, etc., a pitcher can enjoy the game development like a professional baseball game in the real world. For example, it is possible to enjoy the game with a new feeling simply by sequentially updating the player's individual performance and team ranking based on the final performance of each year without changing the game software or the game machine itself.

For game software or game machines such as the above-mentioned professional baseball game, real data is transferred to, for example, an FD (floppy disk) or CD-RO.
M and can be stored on a portable recording medium and distributed to each end user.

Recently, due to the spread of the Internet and the like, a network system for interconnecting computers has penetrated deeply into ordinary households. Therefore, a business form in which the above-described real data is distributed via the Internet is also assumed. Users can provide WWW (Wo) that provides real data.
The user can access the ld Wide Web) site and select the title of the game desired to be purchased from the menu list displayed on the browser screen to receive real data relating to the game. That is, each end user can relatively easily renew the game development by downloading real data via the Internet.

The information distribution to the game user does not include the game software itself, but only the real data portion related to the game. However, real data is
If it is not distributed in a specific data file format that can be deciphered by the program of the game software itself, it cannot be used on the receiving side.

However, in order to unify such file formats, the burden on the distributor or the receiver becomes excessive.

[0012] Further, since information distribution via a network such as the Internet involves the use of a line, a burden such as a communication load on the line and a line use cost is also generated.

[0036]

Embodiments of the present invention will be described below in detail with reference to the drawings.

The present invention proposes to distribute real data for game software using data broadcasting in digital satellite data broadcasting. For example,
When the broadcast program is a professional baseball broadcast, real data such as personal results of players used in baseball games is distributed as a data broadcast. According to such a distribution form, both the information distributor and the receiver have less burden. Further, since the provided real data is associated with the broadcast program, the receiver can smoothly and efficiently perform data processing after reception (that is, installation of data in the game machine, etc.). .

First, a system of the entire digital satellite data broadcasting will be described. However, for the sake of convenience, the digital satellite data broadcasting in Japan will be referred to specifically, but it should be understood that the gist of the present invention is not necessarily limited to this.

FIG. 1 shows a schematic configuration of a digital satellite data broadcasting system 1000 provided for implementing the present invention. As shown in FIG. 1, the digital satellite data broadcasting system includes a broadcasting station (Broadc) that provides a broadcasting service.

order) 10. One or more broadcasting stations 1 exist on the ground, and broadcasting satellites 5 are scattered far above the earth. Further, the receiving stations 10 correspond to general homes and the like, and actually exist innumerable on the ground. Data distribution via the broadcasting station 1 and the broadcasting satellite 5, that is, broadcasting is one-way communication.

Further, between each receiving station 10 and the broadcasting station 1,
It may be bidirectionally connected by a wide area network 7 such as the Internet or a dedicated line (not shown). For example, the Internet 7 can be used as an uplink from the receiving station 10 to the broadcasting station 1. For example, a partial on-demand broadcast service using the Internet 7 can be provided. In this case, the receiving system 10 includes a high-speed analog telephone line of 56 kbps or more, high-speed wireless communication of about 10 to 64 kbps, and a 128 kbps ISDN (Integrat).

rk) or 5 to 30 Mbps class cable.

In Japan, ARIB (Radio Telecommunications Industry Association) is leading the standardization work on digital satellite data broadcasting. According to this, in digital satellite data broadcasting, digital transmission data accompanying a broadcast program is distributed in parallel in addition to real-time video and audio data (real-time AV data) constituting a satellite broadcast program body. . More specifically, MPEG (Motion)
It is transmitted as broadcast waves in the form of a “transport stream” (described later) configured by multiplexing digital transmission data with real-time AV data compressed by a predetermined compression method such as Picture Experts Group 2.

Here, the structure of contents distributed by digital satellite data broadcasting will be described with reference to FIGS.

FIG. 2 schematically shows the structure of broadcast content transmitted as a broadcast wave in digital satellite data broadcasting. As shown in the figure, the broadcast content is an MPEG (Motion Picture Exp).
(Transport stream is composed of OSI (O / Os), which is a multiplex of digital transmission data and real-time AV data compressed by a predetermined compression method such as
pen Systems Interconnection
on) is classified into the transport layer of the reference model).
The former real-time AV data constitutes a satellite broadcast program main body, and the latter digital transmission data constitutes a data broadcast such as broadcast program information attached to the broadcast program main body.

The digital transmission data part is composed of a plurality of data modules. Each data module is
It contains various information associated with the broadcast program body. An example of the broadcast program information is the EPG (Electric P) described above.
(program guide: electronic program information) (E
The PG includes not only presentation information such as a broadcast schedule and a program name of a broadcast program, but also functions such as recording reservation to a VTR. Further, the broadcast program information can include information unique to the broadcast program main body, such as the title and date of the broadcast program main body and the casting of the program.

As shown in FIG. 2, the digital transmission data portion is formed into a data carousel (rotating horse type data), and each data module repeatedly appears during the broadcast of the program main body. . As a result, the receiving system 10 can acquire a data module at an arbitrary timing during a program broadcast period, and can omit a cache memory. Further, an automatic start flag for synchronizing with the display output time of the module can be embedded in the real-time AV data compressed by MPEG2.

FIG. 3 schematically shows the data structure of the data module. As shown in the figure, one data module includes a control program (hereinafter, also referred to as a “multimedia coding application”) that defines the display and output of the data broadcast, a script that defines the operation, It is composed of a plurality of resource elements such as audio, text data, mono-media data such as still images and moving images. Each monomedia data is an object that constitutes a part of the data broadcast, and is handled by the multimedia coding application in an integrated manner.

Each resource element constituting the data module is an independent file having a predetermined format. Audio data includes, for example, AIFF, WAV,
A still image is described in an audio-only file format such as AAC, and a still image is described in an image-only file format such as JPEG, PNG, and GIF. The first resource location information describes position information of each resource element in the data module.

The "multimedia coding application" is a program for controlling the display and output of EPG, advertisement information, and various data broadcasts attached to the broadcast program body. In the ARIB described above, XML (extended Markup) is used as a format (format) for describing a multimedia encoding application.
(Language) -based data broadcasting standardization work is being studied.

XML is a description language in which the definition of tags is arbitrary, that is, there is no restriction on how to describe attributes. Therefore, XML has a high degree of freedom and a high affinity with general-purpose computers and the Internet. Allowing arbitrary definitions of tags is, in other words, intended to treat a character string written in a document as meaningful data. That is, each tag data delimited by the tag can be expressed as data having a meaning other than a mere display purpose by the definition of the tag. Furthermore, by defining the structure of the tag, it is possible to structure and describe the XML instance or the data in the instance.

The distribution content described in the XML language format is given a meaning in accordance with the definition of the tag. Therefore, data that is originally for digital broadcasting can be exchanged between various types of information devices such as computers, televisions, and telephones.

There is no need to construct a special data distribution system in order to convert an XML instance defined by a tag defined for television display as game data, and to create and distribute data contents. The cost burden associated with is also small. In short, data broadcasting can be applied to the distribution of real data used by game software. For example, a game that simulates development related to broadcast programs
If the real data used in the software is distributed in the time zone of the broadcast program, the receiving end user can perform the processing of the received data in conjunction with the broadcast content.

Note that the definition of the tag in the XML instance, that is, the definition of the document type, is based on the DTD (Docum).
ent Type Definition) document. Further, since the XML instance itself does not include style information for specifying an actual expression format, a style sheet may be attached. The style sheet is XSL (extensible Stylesh)

ation).

Also, apart from the style sheet, audio,
A script that defines the operation of multimedia content composed of various types of monomedia data such as text, still images, and moving images may be distributed (for example, the script may be JavaScript, ECMAScript, or Jsc).
It is described in a script language such as "ript". Where X
In standards such as ML and XSL, basically ECMASc
It is defined to write a script with "ript").

FIG. 4 schematically shows a configuration for transmitting digital transmission data in the broadcasting station 1, that is, the transmission system. The transmission system 1 includes a production unit 10
0, a transmission unit 200, and a transmission unit 300.
Hereinafter, each unit will be described.

The production unit 100 corresponds to a site where each content of broadcast program information to be transmitted as digital transmission data is produced. That is, the production unit 100 outputs the XML (eX
Tensible Markup Language)
A style sheet that defines the expression format of a document or its XML document, various types of monomedia data such as still images, moving images, audio, and subtitles (text) as objects included in broadcast program information (hereinafter referred to as “AV / subtitles”) Do)
Create each resource element that makes up the data module.

The XML document is a multimedia encoding application for data broadcasting (described above), and is created using, for example, a commercial authoring tool. XML
The content described in the language format has meaning according to the definition of the tag. Therefore, data originally for digital broadcasting can be exchanged with another information device such as a personal computer or a game machine. There is no need to build a special data distribution system in order to convert XML instances defined by tags defined for television display as game data, and costs related to production and distribution of data contents. The burden is reduced.

These broadcast contents are, for example, LAN (Local Area Ne) laid in the broadcast station 1.
2) to the sending unit 200.

In the sending section 200, the content transmitting system 20
1. Baseband control system 102 and AV encoder 20
3. The transmission data is packetized by each of the subtitle super insertions 205 and passed to the transmission unit 300.

In the transmission section 300, the data of the distribution content, that is, the XML document,
01 and is passed to the content transmission system 302. The combining unit 304 combines output data of each of the content transmission system 302 and the AV subtitle super transmission system 303. Then, the modulation section 305 performs RF modulation on the combined signal and transmits the resultant signal to the receiving station 10 via the RF transmission path.

In the RF transmission path, an RF signal is first transmitted from a transmitting antenna provided in the broadcasting station 1 to the broadcasting satellite 5, and then received by the receiving antenna of the receiving station 10 via the broadcasting satellite 5. .

If real data used in game software that simulates development related to a broadcast program is distributed in the time zone of the broadcast program, the receiving end user can process the received data with the broadcast program. It can be performed in conjunction with the contents of the program body. For example, if a professional baseball program is being broadcast, by distributing a data module storing real data for a baseball game in a data carousel system (described above), viewers, that is, end users, Opportunities for real data acquisition can be easily recalled.

In the receiving system 10, the CPU 11 as a main controller is interconnected with each hardware component via a bus 50, and executes comprehensive control on each component. The receiving system 10 according to the present embodiment includes the game machine interface 7
It is unique in that it is interconnected with the game console 70 via 0A. Hereinafter, each unit will be described.

A broadcast wave received by an antenna (not shown) is supplied to a tuner 51. The broadcast wave conforms to a prescribed format. More specifically, the “transformer” is a “transformer” in which real-time AV data as a broadcast program body and digital transmission data composed of a plurality of data modules in a data carousel are multiplexed. It is configured as a "port stream" (described above). The broadcast wave may be a cable broadcast wave or a terrestrial wave in addition to the above-described broadcast wave, and is not particularly limited.

The tuner 51 tunes a broadcast wave of a predetermined channel, that is, selects a channel according to an instruction from the CPU 11, and outputs received data to a subsequent demodulator 52.
The demodulator 52 demodulates the digitally modulated received data. Note that the configuration of the tuner 11 can be changed or expanded as appropriate depending on whether the transmitted broadcast wave is analog or digital.

The TS decoder 53 interprets this transport stream, separates the transport stream into real-time AV data and MPEG-2 compressed real-time AV data and digital transmission data, and sends the former to the AV decoder 54 and the latter into a bus. The data is transmitted to the CPU 11 via 50. The TS decoder 53 may have a buffer memory 53A for storing work data locally.

Upon receiving the real-time AV data compressed by the MPEG2 system from the TS decoder 53, the AV decoder 54 separates the video data into compressed video data and compressed audio data. The video data is subjected to MPEG2 decompression processing to reproduce the original video signal, and the audio data is subjected to PCM (Pulse Code Modulatio).
n) After decoding, it is synthesized with an additional sound to produce a reproduced audio signal. The AV decoder 54 may have a buffer memory 54A for storing work data locally. The reproduced video signal is output to the display 61 via the multiplexer 55B, and the reproduced audio signal is output to the speaker 62 via the multiplexer 55A.

IEEE 1394 interface 15
Is a serial high-speed interface capable of transmitting and receiving data of about several tens MBps. An IEEE 1394-compatible external device can be daisy-chain connected or tree-connected to the 1 1394 port. In the game machine 70 according to the present embodiment, a game controller 92 for a user (that is, a game player) to input a command or the like to a running game is mounted on the IEEE1394 port.

The game controller 92 outputs an operation signal corresponding to an input operation from the game player.

Card Standard ".

One example of a PC card is an EEPROM (El
electrically erasable and P
This is a memory card including a non-volatile and erasable / rewritable memory chip such as a programmable ROM. However, the removable memory card 93
Is not limited to the form factor of the PC card, and may be a so-called “memory stick”.

The memory card 93 can store various parameters related to the progress of the game, for example. One example of the parameter is real data (described later) which is sequentially referred to in the development of the game. It is preferable that the media for storing the real data also hold the date data when the real data was generated. Further, the memory card 93 can store various data relating to the progress of the game.

As described above, the game machine 70 according to the present embodiment is interconnected with the receiving system 10 via the receiver interface 70B. The receiver interface 70B is dedicated hardware for realizing file transfer such as an XML instance between the bus 85 in the game machine 70 and the receiving system 10.

However, it is sufficient that predetermined data can be transferred between the receiving system 10 and the game machine 70, and the form of the interface provided by the interface 70A is not particularly limited. Furthermore, the receiving system 10
The connection form between the game device 70 and the
It is not limited to a cable connection via 0A. For example, instead of the interface 70A, IR communication may be used. Alternatively, the present invention, which will be described later, is not limited to wired or wireless communication, and has no data transfer interface, and performs data transfer via a portable recording medium such as a memory card 65. Such a processing operation can be similarly realized.

In order to configure the game machine 70,
Many electric circuits and the like other than those shown in FIG. 6 are required.
However, since these are well known to those skilled in the art and do not constitute the gist of the present invention, they are omitted in this specification. Also, it should be noted that only some of the connections between the hardware blocks in the drawings are shown in order to avoid complication of the drawings.

Next, the processing realized in the game machine 70 will be described in detail.

In response to the operation of turning on a power switch (not shown), the game machine 70 is powered on.

At this time, if a recording medium is loaded in the media drive 74, the CPU 71
3 instructs the media drive 74 to read the program data from the recording medium in accordance with the operating procedure specified by the operating system stored in the storage medium 3. The program data on the recording medium is, for example, a “baseball game” that simulates the rules of baseball, and data related to the game.

The media drive 74 reads the image data, audio data, and program data stored in the loaded recording medium in accordance with a read command from the CPU 71.
Read data etc. The read data is subjected to error correction processing in a decoder 75.

The image data after the error correction processing is transferred to the bus 8
After being supplied to the decompressing device 81 via 5 and subjected to decompression processing, it is supplied to the drawing processor 79 and written in the non-display area of the buffer memory 79A.

Further, the audio data after the error correction processing is
The data is supplied to the main memory 72 or the audio processor 80 and is written to the main memory 72 or the buffer memory 80A.

The program data after the error correction processing is supplied to the main memory 72 and written.

The CPU 71 starts the program data loaded in the main memory 72, that is, the game, and in accordance with an instruction command input from the user (ie, a player) through the game controller 92,
Control game development. That is, control of image processing and sound processing and control of other internal operations are appropriately performed in accordance with the contents of instructions from the player.

The result of the overall control by the CPU 71 is T
Screen output and audio output are performed via the V monitor 91, and the player can play while observing the progress of the game.

By the way, the contents of instructions from the player via the game controller 92 include updating of real data related to the game. For example, if the game body is a virtual professional baseball game simulating professional baseball in the real world, the real data is
Competition record of each professional baseball team in the real world, personal record of each professional baseball player (for fielders, it is the number of hits such as number of home runs, batting average, batting average, RBI, victory RBI, etc. , ERA, strikeout, etc.).

On the game screen activated by the program data read from the recording medium, one or more selection menu icons for, for example, starting a game or inputting a player name are provided. The selection operation is performed via the keyboard. The real
The update of data is displayed as an icon as one of the options in the selection menu. Alternatively, a dedicated button for instructing the update of the real data may be prepared on the game controller 92.

The game player can instruct updating of real data by selecting an icon or operating a button. Then, in response to the input of the update instruction, the real data update routine starts. The computer program describing the real data update routine is read from, for example, the same recording medium that stores the program data of the game main body.
However, in realizing the present invention, the mode of providing the real data update program itself is not particularly limited. For example, the program may be stored in the ROM 73 in the game machine 70 in advance.

When the real data update routine is started, the CPU 71 sets the broadcasting station 1 for digital satellite data broadcasting.
Receives from the receiving system 10 via the receiver interface 70B, and temporarily writes it to the main memory 72.

According to the standardized specification developed mainly by ARIB, a multimedia encoding application is an XML instance described in an XML language format (described above). The broadcasting station 1 distributes digital transmission data formed by converting a plurality of data modules including an XML instance into a data carousel (rotating horse) together with a broadcast program body composed of real-time AV data (described above). That is, the same XML instance is repeatedly delivered during the broadcast of the program, so that the receiving system 1
No. 0 can receive an XML instance at an arbitrary timing during program broadcasting and transfer it to the game machine 70 side.

Then, the CPU 71 stores the main memory 7
2 from one or more XML instances stored in
A search is made to see if there is any data that can be used in the game currently being played. Since XML is a type of language in which data attributes are defined using tags (described above), it is easy to determine the presence or absence of data corresponding to a game by referring to the data that is defined by the tag definition in the XML instance. You can judge.

In general, data having information related to a broadcast program main body is written in the digital transmission data.
If real data usable for game software having progress related to a broadcast program (or simulating the broadcast program) is distributed in the time zone of the broadcast program,
For the end user on the receiving side, the processing operation on the received data can be performed in conjunction with the contents of the broadcast program body. For example, if a professional baseball program is being broadcast, if a data module storing real data for a baseball game is distributed by the data carousel method (described above), the viewer, that is, the game player will be・ Easily recall opportunities and time zones where data can be obtained.

Hereinafter, a processing procedure for acquiring real data will be described more specifically, taking a baseball game simulating professional baseball in the real world as an example.
FIG. 7 illustrates the processing procedure in the form of a flowchart. However, in this example, the satellite broadcast is broadcasting a professional baseball broadcast, and a multimedia encoded data broadcast for the purpose of displaying player results on a screen is performed simultaneously and in parallel with the relay broadcast. It is assumed that Less than,
Each step of the flowchart will be described.

A game player can instruct updating of real data by selecting an icon or operating a button. Then, in response to the input of the update instruction, the real data update routine starts. The computer program describing the real data update routine is read from, for example, the same recording medium that stores the program data of the game main body.

In the updating routine, first, the X received by the receiving system 10 as a part of the broadcast content is
The ML instance has the interface 70A, 70B
Via the main memory 72 in the game machine 70
(Step S11).

A team selection screen is displayed on the screen of the TV monitor 91, and the player of the game uses the game controller 92 to select the name of the team whose data is to be updated (step S12).

In response to the team name selection operation, it is determined whether or not data corresponding to the selected team exists in the XML instance (step S13). X
An ML instance is a DTD (Document Ty
The data attribute is arbitrarily defined by defining a tag by a (pe Definition) document (described above). Therefore, the presence or absence of the relevant data can be easily determined by referring to the data meaningful by the definition of the tag in the XML instance.

If data on the corresponding team cannot be found in the XML instance, step S
Proceeding to 14, the error message such as "There is no data for the selected team" is displayed on the screen of the TV monitor 91, but the data update process is not performed.

On the other hand, if the data of the corresponding team can be found in the XML instance, the flow advances to step S15 to extract the date data written in the XML instance. Next, in step S16, this XM
The date data of the L instance is compared in magnitude with the date data relating to the real data of the team currently in use. The real data currently used and its date data are written in the memory card 93, for example.

When the date data of the XML instance is not large, that is, not new, there is no point in updating the real data. Therefore, in this case, the process proceeds to step S17, and only an error message such as "the data of the selected team has been updated" is displayed on the screen of the TV monitor 91, and the data updating process is not performed.

On the other hand, if the date data of the XML instance is large, that is, if it is new, step S18
To execute the data update process. More specifically, necessary real data is sequentially extracted from the XML instance, and is replaced with real data currently in use held in the memory card 93 or the like.

After the real data update process is completed in step S18, or after an error message is displayed in step S14 or S17, a confirmation screen for continuing the real data update process appears on the TV monitor 91.
Displayed above (step S19). The game player can respond to the confirmation screen via, for example, the game controller 92.

When the player instructs the end of the data update work, the entire processing routine ends. On the other hand, if the user instructs to continue the data update, step S
Then, the process returns to step S12 and the same processing as above is repeatedly executed to continue updating the real data.

According to the processing procedure defined by the flowchart shown in FIG. 7, it is possible to easily convert multimedia-encoded data for displaying player results and the like on a screen as real data for a game. Please fully understand.

Note that the connection between the receiving system 10 and the game machine 70 is not limited to the cable connection using the interfaces 70A and 70B, but may be a wireless connection using IR communication or the like. Alternatively, data may be transferred via a memory card (described above).

By configuring 005 with a nonvolatile storage device, the progress of the game is not lost even when the power of the game machine 70 is shut off. For example, even if the game being executed is interrupted, the game can be restarted from the point of interruption by accessing the progress storage unit 1005, fetching and activating the stored progress data.

The game introduced into the game machine 70
Software is used to create real-world events (for example,
