[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 shows a configuration diagram of an embodiment of a peer-to-peer network for realizing the program production method of the present invention. In FIG. 1, peers 1 to 6 constitute a peer-to-peer network. Here, it is assumed that the peer-to-peer network is constructed by, for example, a SIONet (semantic information network) that does not require an intermediary (broker) to search for and discover peers.
[0014]
In the present invention, arbitrary peers 1 to 6 constituting a peer-to-peer network can transmit material data such as a video material, an audio material, a text, a CG (Computer Graphics) model, a program script template, etc. Disclose on the two-peer network, and distribute the metadata as an index of the published material data to the peer-to-peer network.
[0015]
When an arbitrary peer (for example, peer 6) logs on to the peer-to-peer network, the metadata of material data published to the peer-to-peer network is acquired from peers 1 to 5. Then, based on the acquired metadata, the desired material data is searched, and the position on the peer-to-peer network where the desired material data exists, that is, the identification information of the peer that provides the desired material data is metadata. To get from.
[0016]
Then, the peer 6 that performs reproduction directly connects to peers (for example, peers 1 to 5) that provide the desired material data, and downloads or streams the desired material data. In this manner, a desired program content is generated and reproduced by combining the collected material data collection on one peer.
[0017]
FIG. 2 shows a hardware configuration diagram of an embodiment of the peer. In FIG. 1, an input device 11 includes a keyboard, a mouse, and the like, and inputs various operation signals. The display device 12 displays various windows, program contents, and the like. The interface device 13 includes a modem, a router, and the like, and is used for connecting to a network.
[0018]
The program executed by the peer is installed from a recording medium 15 such as a CD-ROM mounted on the drive device 14 to an auxiliary storage device 16 such as a hard disk, and executed by the arithmetic processing unit 17. The auxiliary storage device 16 stores various files and data. The arithmetic processing unit 17 uses the memory device 18 as a work area when executing the program. These input devices 11 to 18 are interconnected by a bus B.
[0019]
Software having the same function is installed in each of the peers 1 to 6. FIG. 3 shows a functional block diagram of one embodiment of the peer. In the figure, a publishing function unit 20 publishes material data to a peer-to-peer network. The associating function unit 21 associates metadata with the published material data, and shares and distributes the metadata via a peer-to-peer network.
[0020]
The search function unit 22 searches for desired material data based on distributed metadata. The download or streaming function unit 23 directly connects to a peer that provides desired material data, and downloads or streams desired material data. The program content generation function unit 24 generates program content by combining the acquired material data. The program content reproduction function unit 25 reproduces the program content generated by the program content generation function unit 24.
[0021]
Therefore, each of the peers 1 to 6 can be a peer that provides material data (providing peer) or a peer that generates and reproduces program content (reproduction peer). For example, in the case of a peer such as a mobile phone or a PDA (Personal Digital Assistants), whose hardware performance is lower than that of a personal computer or the like, the connection / disconnection is frequently repeated by wireless connection, the program content generation function unit 24 You can also have only.
[0022]
First, login to a peer-to-peer network will be described. When the peer 6 logs in to the peer-to-peer network, as shown by a broken line in FIG. A copy is obtained and stored in the auxiliary storage device in the peer 6.
[0023]
Further, the peer 6 creates metadata of the material data to be disclosed, distributes the metadata to the peer-to-peer network as shown by a broken line in FIG. .
[0024]
FIG. 5 shows an example of the metadata. The left column is the metadata of the text, and the right column is the metadata of the moving image. As metadata, URL (Uniform Resource Locator) as identification ID, title, summary, keyword, link destination (URL), release date and time, data size, media type, copyright, distribution type (download / streaming playback), transmission It describes the nationality, language used, category, amount of money, etc., and may also describe other items such as access rights.
[0025]
The peer 2 searches for necessary information from a plurality of metadata obtained from the peer-to-peer network. From one or a plurality of metadata obtained by this search, an identification 1D (URL) of one or a plurality of peers that have disclosed necessary material data is obtained. Then, one-to-one connection is made to each of one or a plurality of peers, and various kinds of material data are collected from the peers 1 to 5 as shown by arrows in FIG.
[0026]
In FIG. 6, the peer 6 acquires material data of a news article (text) from the peer 1, acquires material data of a sports video from the peer 2, and acquires material data of a CG (Computer Graphics) model from the peer 3. , The material data of the program script template is acquired from the peer 4, and the music material data is acquired from the peer 5. The peer 6 generates and reproduces the program content based on the collected material data group.
[0027]
FIG. 7 is a flowchart illustrating an example of a metadata acquisition process executed when each peer logs in to the peer-to-peer network. When this process is executed for a predetermined time, the process is terminated by a timer interrupt.
[0028]
In the figure, in step S10, an acquisition request indicating what category of material data is desired is issued to the partner peer connected one-to-one with the own peer. When the peer receiving the acquisition request has the material data desired by the acquisition request, the peer transmits metadata relating to the material data. If not, a response to that effect is created, but if the peer having the desired material data is known, the identification ID of the peer is added to the response and transmitted.
[0029]
Next, in step S12, metadata or a response message transmitted in response to the acquisition request from the partner peer is received, and in step S14, it is determined whether or not the metadata is received. Stores the received metadata in the auxiliary storage device in its own peer in step S16, and proceeds to step S10.
[0030]
If the response message has been received, the process proceeds to step S18, where the connection is switched to the peer with the identification ID added to the response message or another peer that has not issued the acquisition request, and the process proceeds to step S10.
[0031]
FIG. 8 is a flowchart of an embodiment of a reproducing process performed by a reproducing peer that generates and reproduces program content, FIG. 9 is a flowchart of an embodiment of a providing process performed by a providing peer that provides material data, and FIG. 4 shows a flowchart of an embodiment of a charging process executed by a charging server, respectively. Note that the billing server is one peer connected to the peer-to-peer network.
[0032]
In FIG. 8, in step S22, the playback peer searches the metadata stored in the auxiliary storage device for material or effect metadata required for program generation. If the metadata of the required material or effect is found, the process proceeds from step S24 to step S26, where a one-to-one connection is made with a peer (providing peer) having the identification ID of the found metadata. It requests the peer (providing peer) to download or stream the material data corresponding to the discovered metadata.
[0033]
Thereafter, in step S28, material data downloaded or streamed from the providing peer in response to the request is acquired and stored in the auxiliary storage device. In step S30, it notifies the accounting server that downloading or streaming has been performed.
[0034]
Next, in step S32, it is determined whether or not the search for the material or effect metadata required for program generation has been completed. If not completed, the process proceeds to step S22, and if completed, the process proceeds to step S34. In step S34, an automatic program creation process is performed, the program created in the next step S36 is reproduced, and the process ends.
[0035]
In FIG. 9, the providing peer publishes the material data stored in its own auxiliary storage device to the peer-to-peer network in step S42. Thereafter, in step S44, it is determined whether there is a request for downloading or streaming the material data from the reproduction peer to the own peer, and if there is no request for downloading or streaming, step S44 is repeated.
[0036]
If it is determined that there is a download or streaming request, the process proceeds to step S46, where the material data is downloaded or streamed to the playback peer. Thereafter, in step S48, the fact that downloading or streaming has been performed is notified to the accounting server, and the process proceeds to step S44.
[0037]
In FIG. 10, the peer as the charging server determines in step S52 whether or not there is a download or streaming notification from the reproducing peer and the providing peer, and if there is no download or streaming notification, repeats step S52. If it is determined that there is a download or streaming notification, the flow advances to step S54 to request the playback peer for the amount included in the metadata of the material data as a value for the download or streaming.
[0038]
In step S56, the unit price of download or streaming is paid to the providing peer, and the process proceeds to step S52. The unit price for the providing peer is set lower than the price for the reproducing peer, so that the charging server can obtain a profit as a commission from the difference between the price and the unit price.
[0039]
Here, the operation of the program content generation function unit 24 in the reproduction peer will be described. The program content generation function unit 24 has a function corresponding to the program generation profile generation device and the program automatic generation device (viewing terminal) described in Japanese Patent Application No. 2001-351512. The program content generation function unit 24 generates program content by combining a plurality of collected material data.
[0040]
Here, the program script template is described, for example, by TVML (TV Program Making Language), and the program script template described by TVML will be described.
[0041]
For example, in the case to various greeting depending on the time of day to the CG character, character: talk (name = BOB, text = "$ (Greeting)") When you create a named template, by the time a part of the $ (Greeting), "Hello "Or" Good evening ", a script for automatically giving a greeting is generated.
[0042]
In the program script template of the program setup shown in FIG. 11A, the file path of the model data of the CG set of the material data obtained from the other peer is replaced with ＄ (CG_MODEL_DATA) on the second line, and ＄ on the third line. (CGCASTER_MODEL_DATA) is replaced with the file path of the model data of the CG caster. Further, the standing position of the caster is set in the sixth line, and the voice quality of the caster is set in the seventh line. In addition, the position, direction, intensity, color, and camera angle of the CG lighting (set division), and the position of a virtual monitor (so-called re-imaging monitor) in the CG set are defined.
[0043]
In the program script template for generating headline news shown in FIG. 11B, first, BGM is played, a title image of the headline news is displayed, and the caster makes a foreword of "domestic and overseas headline news". Do. After that, the title (text) of the news of the material data obtained from another peer is superimposed and displayed, and the caster explains the news. Note that ＄ (JOINT) is replaced with a connecting line such as “continue”, ＄ (NEWS_TITLE) is replaced with a news title, and ＭＥ (COMMENT) is replaced with a detailed commentary on the news.
[0044]
The above-described program script template is a part of a small part of the script constituting the program, and exists for each scene of the program. In FIG. 6, the program script template is obtained from the peer 4 for the sake of explanation. However, in practice, many program script templates are obtained from a large number of peers open to the peer-to-peer network. . How to combine and use the many program script templates acquired in this way is determined freely by the peer that performs the reproduction.
[0045]
For example, when video data of a typhoon track map, text data of the title, CG model data of a weather commentator, and audio data of an announcement made by a weather commentator are collected as material data, a program content generation function is provided. As shown in FIG. 12, the program contents for displaying the typhoon course prediction diagram 31, the title 32, and the CG 33 of the weather commentator on the screen as shown in FIG. 12, and making an announcement in accordance with the movement of the mouth of the CG 33 of the weather commentator Is generated, and the program content is reproduced by the program content reproduction function unit 25. The text enclosed by a solid line 34 shown in the lower part of FIG. 12 indicates the content of the announcement.
[0046]
In this way, each peer can be both a material data provider and a user, and the information source can suppress the uniformity and promote the supply of various program contents.
