Abstract

PROBLEM TO BE SOLVED: To solve the problem that even the animation data of any moving image which does not interest a user so much are distributed through a network 1 since once the distribution of animation data is started from a server 6, the distribution of the animation data is continued until the stop of the distribution is requested to from a terminal 2 to the server 6, or until the stop of the distribution is voluntarily performed by the server 6. SOLUTION: At the time of accepting the distribution condition of a moving image from a terminal 12 through the Internet 11, a server 16 retrieves the moving image matched with the distribution condition, and distributes the animation data of the moving image through the Internet 11 to the terminal 12.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data distribution system and a data distribution method for distributing moving image data of a moving image using a communication network.

[0002]

2. Description of the Related Art FIG. 4 shows, for example, "Interface J".
an. 2000, page 120 to page 126, is a configuration diagram showing a conventional data distribution system, in which 1 is an Internet serving as a communication network, 2 is a terminal used by a user, and 2 is a terminal used by a user. It has a function of transmitting a moving image data distribution request, receiving moving image data from the server 6 via the Internet 1, and displaying a moving image on the monitor 3 according to the moving image data. A monitor 3 displays a moving image.

[0003] 4 is a subject, 5 is a camera for photographing the subject 4, 6 is a moving image photographed by the camera 5,
The server 6 stores the moving image data, which is the encoded data, in a state in which the moving image data can be distributed to the terminal 2 on the Internet 1. When the server 6 receives a distribution request of the moving image data from the terminal 2 via the Internet 1, the server 6 Internet 1
It has a function of distributing to the terminal 2 via the terminal. FIG. 5 is a time chart showing transmission and reception of data among the camera 5, the server 6, the terminal 2, and the monitor 3.

Next, the operation will be described. The moving image of the subject 4 captured by the camera 5 is supplied to the server 6,
The server 6 encodes the moving image, stores the moving image data as the encoded data in a state where the moving image data can be distributed to the terminal 2 on the Internet 1, and discards the moving image data after a predetermined time.

[0005] Before the moving image data is discarded, when the user transmits a request for distribution of the moving image data to the server 6 via the Internet 1 using the terminal 2, the distribution of the moving image data from the server 6 via the Internet 1 is started. Be started. Terminal 2
Receives the moving image data from the server 6, reproduces a moving image according to the moving image data, and displays the moving image on the monitor 3. The distribution of the moving image data is continued until the terminal 2 requests the server 6 to stop the distribution or the server 6 voluntarily stops the distribution.

In the example of FIG. 5, the camera 5 sends a moving image A, a moving image B, a moving image C, a moving image D, a moving image E, a moving image F, a moving image G, and a moving image H to the server 6. Has been sent.
Each of the moving images A to H symbolically shows a moving image for a certain period. In such a state, when the server 6 receives the distribution request of the moving image data from the terminal 2 via the Internet 1, the server 6 distributes the moving image data of the moving image received from the camera 5 to the terminal 2 via the Internet 1 thereafter. In the example of FIG. 5, the moving image data BF of the moving images BF is distributed to the terminal 2.

When the terminal 2 receives the moving image data BD from the server 6 via the network 1, the terminal 2
ＤD are decoded and the reproduced moving images BD are output to the monitor 3, whereby the monitor 3 displays the reproduced moving images BD.
However, in the example of FIG. 5, after the terminal 2 receives the moving image data D, the user transmits a request to stop the distribution of the moving image data to the server 6 using the terminal 2.
F is not decoded. Note that, upon receiving the distribution stop request from the terminal 2 via the network 1, the server 6 stops the distribution of the moving image data thereafter. Therefore, the moving image data G is not distributed.

[0008]

Since the conventional data distribution system is configured as described above, when the distribution of moving image data is started from the server 6, the terminal 2 transmits the moving image data to the server 6.
, Or until the server 6 voluntarily stops distribution. For this reason, even if a moving image is of little interest to the user, the network 1
There is a problem that video data is distributed through the Internet.

[0009] Further, unless the user decodes the moving image data and displays the moving image on the monitor 3, the user cannot determine whether or not the moving image is required by the user.
Needs to constantly receive and decode moving image data and display the moving image on the monitor 3. As a result, there is a problem in that network resources such as energy and line capacity consumed by the terminal 2 tend to be wasted.

[0010] Furthermore, if such a moving image drips, the convenience is the same as that of a television broadcast, so that moving image transmission via a communication network that tends to have lower image quality than that of a television broadcast is less competitive. As a result, there has been a problem that the data distributor cannot obtain proper profit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below. Embodiment 1 FIG. FIG. 1 is a configuration diagram showing a data distribution system according to Embodiment 1 of the present invention.
Reference numeral 1 denotes an Internet serving as a communication network; 12 denotes a terminal used by a user; the terminal 12 sets a distribution condition of a moving image, transmits the distribution condition, and transmits a moving image of the moving image that matches the distribution condition. Upon receiving the data, it has a function of displaying a moving image on the monitor 13 in accordance with the moving image data. A monitor 13 displays a moving image.

Reference numeral 14 denotes a subject, 15 denotes a camera for photographing the subject 14, 16 denotes a state in which a moving image photographed by the camera 15 is encoded, and moving image data as the encoded data can be distributed to the terminal 12 on the Internet 11. The server 16 is connected to the terminal 12 via the Internet 1
When a distribution condition of a moving image is received via the Internet 1, a function of searching for a moving image that matches the distribution condition and distributing moving image data of the moving image to the terminal 12 via the Internet 11 is provided. FIG. 2 is a time chart showing a data distribution method according to the first embodiment of the present invention.

Next, the operation will be described. The moving image of the subject 14 photographed by the camera 15 is supplied to the server 16, which encodes the moving image and transmits the encoded moving image data to the terminal 1 on the Internet 11.
2 and are discarded after a certain period of time.

Before the moving image data is discarded, when the user transmits a moving image distribution condition to be described later to the server 16 via the Internet 11 using the terminal 12,
From 6, the distribution of the moving image data of the moving image matching the distribution condition is started via the Internet 11. Terminal 12
When receiving moving image data from the server 16, the moving image is reproduced according to the moving image data and the moving image is displayed on the monitor 13. The distribution of the moving image data is performed by the terminal 1
2 to the server 16 to request the stop of the distribution or the server 16 voluntarily stops the distribution.

In the example shown in FIG.
, A moving image A, a moving image B, a moving image C, a moving image D,
A moving image E, a moving image F, a moving image G, a moving image H,..., A moving image N are transmitted. Each of the moving images A to N symbolically represents a moving image for a certain period. In this state, when the user uses the terminal 12 to determine a condition of a moving image to be viewed on the terminal 12 (delivery condition of the moving image), the terminal 12 transmits the distribution condition to the server 16.

Here, there are the following moving image distribution conditions. For example, in a professional baseball broadcast of a giant game on X / Y, there may be a case where it is desired to distribute a moving image in which an appearance scene of an M player or a T player or a hit scene of someone is shot. In this case, the user sets the following distribution conditions. Delivery condition = xxx (++) However, X / Y, professional baseball broadcast giant game M player T player Someone's hit

Upon receiving the distribution conditions from the terminal 12 via the Internet 11, the server 16 searches the moving images received from the camera 15 after receiving the distribution conditions for a moving image that matches the distribution conditions. Then, the moving image data of the moving image is distributed to the terminal 12 via the Internet 11. For example, when the moving image E matches the distribution condition, the moving image data E in which the moving image E is encoded is distributed to the terminal 12.
At this time, if the distribution of the moving image data E cannot be started immediately, the moving image data E is transferred to the server 1 for a necessary time.
6 and then distributes all of the moving image data E. If it is not necessary to distribute all of the video data E,
The moving image data E until the start of the distribution is discarded, and the moving image data E from the time when the distribution is started is distributed. In the example of FIG. 2, the server 16 transmits a server / terminal connection request when distributing the moving image data E. However, the terminal 12 and the server 16 are always connected as in packet transmission. In this case, it is not always necessary to transmit the server / terminal connection request.

When the terminal 12 receives the moving image data E from the server 16 via the network 11, the terminal 12 decodes the moving image data E and outputs the reproduced moving image E to the monitor 13, so that the monitor 13 indicate. In the example of FIG. 2, the moving image F following the moving image E is also determined by the server 16 as the moving image F
Is delivered to the terminal 12. When the terminal 12 receives the moving image data F from the server 16 via the network 11,
The moving image data F is decoded and the reproduced moving image F is displayed on the monitor 13.
, The monitor 13 displays the reproduced moving image F.

In the example of FIG. 2, since the moving image G following the moving image F does not match the distribution condition, the moving image data G of the moving image G is not distributed from the server 16 to the terminal 12. Thereafter, a search is made for a moving image that matches the distribution condition. Since the moving image I matches the distribution condition, the moving image data I of the moving image I is distributed to the terminal 12. When the terminal 12 receives the moving image data I from the server 16 via the network 11, the terminal 13 decodes the moving image data I and outputs the reproduced moving image I to the monitor 13 so that the monitor 13 displays the reproduced moving image I.

When the user operates the terminal 12 to stop the distribution of the moving image data or sets a timer in advance, the terminal 12 transmits a distribution stop request to the server 16. The server 16 that has received the distribution stop request does not distribute the moving image data to the terminal 12 thereafter.

In the above example, the server 16 checks whether or not the contents of the moving image received from the camera 15 are compatible with the distribution conditions received from the terminal 12. Is distributed to the terminal 12, but the distribution conditions received from the terminal 12 do not relate to the contents of the moving image, and whether or not the distribution conditions are satisfied is determined not from the contents of the moving image itself. , Server 1
6 can use any information, for example, information set in the server 16 by the administrator of the server 16, information accumulated in the past regarding the subject 14,
Whether or not the person watching the moving image No. 5 satisfies the above condition may be determined based on information set in the server 16 or the like.

As is clear from the above, the first embodiment
According to this, when receiving a moving image distribution condition from the terminal 12 via the Internet 11, the server 16 searches for a moving image matching the distribution condition, and distributes the moving image data of the moving image to the terminal 12 via the Internet 11. With such a configuration, it is possible to display only a moving image desired by the user, and it is possible to effectively use network resources.

When the terminal 12 has the function of receiving a mobile phone, the line connection wait state is maintained until the server 16 starts distributing the moving image data via the Internet 11, and the server 16 sets the distribution condition. Since the terminal 12 can be connected to the Internet 11 only when the moving image data of the moving image matching the above is distributed, the use of the Internet 11 accompanying the reception of unnecessary moving image data can be avoided. Therefore, payment of useless use cost of the Internet 11 is exempted, and power consumption of the terminal 12 can be reduced.

The server administrator can also select a moving image required by the user, so that a service different from that of ordinary television broadcasting can be provided to the user, and an opportunity for the user to set conditions desired for distribution. Alternatively, each time video data is distributed to a terminal by a telephone function, a network usage fee or a distribution service fee can be collected. For a network manager such as a telephone service provider, the amount of data information can be reduced, so that the Internet 11 can be used effectively. Also, every time the terminal 12 is connected to the Internet 11 by a telephone function, Usage fees,
This can be an opportunity to collect a distribution service fee.

Embodiment 2 FIG. 3 is a time chart showing a data distribution method according to the second embodiment of the present invention. In the second embodiment, an operation when a telephone is mounted on the terminal 12 and the server 16 will be described.

In the example of FIG. 3, the camera 15
, A moving image A, a moving image B, a moving image C, a moving image D,
A moving image E, a moving image F, a moving image G, a moving image H,..., A moving image N are transmitted. Each of the moving images A to N symbolically represents a moving image for a certain period.

In such a state, the user operates the terminal 12
, A terminal connection request is transmitted from the terminal 12 to the terminal-side telephone. Upon receiving the request, the terminal-side telephone sends a line connection request to the server-side telephone function access unit (or a relay point that is always connected to the telephone line), and the terminal-side telephone and the server-side telephone function access unit Request a line connection. The server-side telephone function access unit returns a line connection response to the terminal-side telephone when connection preparation is completed. The terminal-side telephone receiving this returns a telephone connection completion response to the terminal 12. Thereby, the terminal 1
This means that a network route for transmitting data from the second to the server 16 has been secured.

Next, when the user uses the terminal 12 to set the conditions of the moving image to be viewed, the distribution conditions are transmitted to the server 16 using the above-mentioned network route. These operations simply determine the conditions of the moving image that the user wants to watch on the terminal 12, and thereafter the terminal-side telephone of the terminal 12 automatically operates the telephone line and sends the distribution conditions to the server 16. You may enable it to transmit. Then, the terminal 12
Transmits a telephone line disconnection request to the terminal-side telephone, and upon receiving the request, the terminal-side telephone 16 transmits a line disconnection request to the server-side telephone function access unit. As a result, the connection by the telephone line between the terminal-side telephone and the server-side telephone access response unit is interrupted, and the user can put the terminal-side telephone in a call waiting state, so that the power consumption of the terminal-side telephone and the terminal 12 is reduced. Can be reduced.

When receiving the distribution conditions from the terminal 12 via the Internet 11, the server 16 searches the moving images received from the camera 15 after receiving the distribution conditions for a moving image that matches the distribution conditions. . For example, moving image D
In the case where the distribution conditions are met, the following processing is performed.

The server 16 sends a telephone connection request to the server-side telephone function access unit. Upon receiving the telephone connection request, the server-side telephone function access unit transmits the line connection request to the terminal-side telephone. The terminal-side telephone receiving this line connection request transmits a line connection response to the server-side telephone function access unit as soon as it is ready to receive data. At this time, the terminal-side telephone receiving the line connection request may automatically transmit the line connection response, or the user may intentionally operate the terminal 12 or the terminal-side telephone to transmit the line connection response. You may. Upon receiving the line connection response, the server-side telephone function access unit transmits a telephone connection completion response to the server 16. As a result, a network path for distributing moving image data is secured between the server 16 and the terminal 12.

Next, the moving image data D of the moving image D that matches the distribution conditions set by the terminal 12 is distributed to the terminal 12. At this time, the telephone connection request from the server 16, the line connection request of the server-side telephone function access unit receiving the request, the line connection response of the terminal-side telephone receiving the request, and the telephone connection of the server-side telephone function access unit receiving the request The connection completion response is received by the server 16, and the server 16 transmits the moving image data D to the terminal 1.
In the case where it takes a long time to start the transmission in Step 2, the moving image data D generated during that time may be stored in the server, and after the data transmission is started, all of the moving image data D may be distributed. . Alternatively, the moving image data D until the connection is secured may be discarded, and the moving image data D from the time when the network route is secured may be delivered. Further, the image quality of the moving image data to be delivered may be changed according to the data transferable amount of the secured network route or the capacity of the server 16.

Upon receiving the moving image data D from the server 16 via the network 11, the terminal 12 decodes the moving image data D and outputs the reproduced moving image D to the monitor 13 so that the monitor 13 indicate. If the moving image E following the moving image D also satisfies the distribution condition, the server 16 continues to transmit the moving image data E of the moving image E to the terminal 12.
Deliver to. The terminal 12 is connected from the server 16 to the network 1
When the moving image data E is received via
Is decoded and the reproduced moving image E is output to the monitor 13, whereby the monitor 13 displays the reproduced moving image E.

If the moving image F following the moving image E does not satisfy the distribution condition, the server 16 transmits a telephone line disconnection request to the server-side telephone access responding unit. A line disconnection request is transmitted to the terminal-side telephone. As a result, the connection via the telephone line between the server-side telephone access response unit and the terminal-side telephone is interrupted, and the user can place the terminal-side telephone in a call waiting state, thereby reducing the power consumption of the terminal-side telephone. it can. Also, since the terminal 12 does not need to create a reproduced moving image from the moving image data during this time, power consumption can be reduced. That is, until the terminal-side telephone receives an incoming call,
The power consumption of the terminal 12 can also be reduced since the terminal 12 can also be turned off to be in the standby state.

The server 16 then searches for a moving image that satisfies the distribution condition. If the moving image I satisfies the distribution condition, the server 16 communicates with the terminal 12 in the case of the moving image D. In the same manner as described above, the video data I of the moving image I is distributed to the terminal 12 after securing the network route.
The terminal 12 decodes the reproduced moving image I from the moving image data I, transmits the decoded moving image I to the monitor 13, and displays the reproduced moving image.

When the moving image J following the moving image I does not satisfy the distribution conditions, the connection between the server-side telephone function access unit and the terminal-side telephone is established by the telephone line, as in the case of the moving image F. Interrupt. When the user transmits a distribution stop request from the terminal 12 to the server 16 because the user performs a service stop operation using the terminal 12 or sets a timer in advance, the server 16 that has received the distribution stop request Does not distribute the moving image data to the terminal 12 thereafter. Also, when the user operates the terminal 12 or the terminal-side telephone to transmit a telephone disconnection request or a line disconnection request, the server 16 stops or terminates the distribution of the moving image data.

As is clear from the above, this embodiment 2
According to this, when receiving a moving image distribution condition from the terminal 12 via the Internet 11, the server 16 searches for a moving image matching the distribution condition, and distributes the moving image data of the moving image to the terminal 12 via the Internet 11. With such a configuration, it is possible to display only a moving image desired by the user, and it is possible to effectively use network resources.

In the second embodiment, the function of the server-side telephone function access unit has been described as being incorporated in the server 16, but the present invention is not limited to this.
For example, it may be somewhere on the network 11.

Embodiment 3 In the second embodiment, when the server-side telephone function access unit transmits a line connection request in response to the telephone connection request from the server 16, the terminal-side telephone automatically returns a line connection response, and the server-side telephone function access When the server 16 starts distributing the moving image data by returning the telephone connection response completion, the server 16 sends the moving image data distribution start notification to the terminal 12 when the server 16 starts distributing the moving image data. , And the distribution of the moving image data may be started when the notification of the acceptance of the moving image data is received from the terminal 12. As a result, it is possible to distribute the moving image data after confirming the user's intention.

Embodiment 4 Although not specifically mentioned in the first and second embodiments, the distribution service fee may be charged to the mobile phone (telephone) of the terminal 12 every time the server 16 distributes the moving image data. However, the method of collecting the distribution service fee is not limited to the charging for the mobile phone, and for example, the moving image distributor may directly charge using a credit card or the like. As a result, the distribution service fee is charged only when the necessary moving image data is distributed to the user, so that there is an effect that a reasonable fee collection system can be constructed.
In addition, the terminal 1 determines the amount of video data to be distributed from the server 16 to the terminal 12 and the line connection time required for the information.
The second telephone may be charged.

Embodiment 5 FIG. In the fourth embodiment, the case where the server 16 charges the telephone of the terminal 12 every time the server 16 distributes the moving image data. However, the server 16 distributes the moving image data of the moving image that matches the distribution condition. In doing so, a distribution service fee corresponding to the degree of matching of the distribution conditions may be charged to the mobile phone (telephone) of the terminal 12. However, the method of collecting the distribution service fee is not limited to the charging for the mobile phone, and for example, the moving image distributor may directly charge using a credit card or the like.

Thus, if the distribution condition is satisfied by 100%, a distribution service fee of, for example, 12 yen is collected, but if the distribution condition is satisfied by 50%, only a distribution service fee of 10 yen is collected. To build a toll collection system. For example, in a case where a hit scene of a giant M player is set as a distribution condition, if a moving image of the hit scene exists, 12 yen is charged by distributing moving image data of the moving image, and If there is no moving image of the scene, it may be possible to charge 10 yen by distributing moving image data of a hit scene other than a hit.

Embodiment 6 FIG. In the above-described fourth embodiment, the distribution service fee is charged to the telephone set of the terminal 12 every time the server 16 distributes the moving image data. However, according to the image quality of the reproduced image based on the moving image data distributed from the server 16, The distribution service fee may be charged to the mobile phone (telephone) of the terminal 12. However, the method of collecting the distribution service fee is not limited to the charging for the mobile phone, and for example, the moving image distributor may directly charge using a credit card or the like.
As a result, a higher delivery service fee can be charged for a delivery service with a higher image quality, so that a rational fee collection system can be constructed.

Embodiment 7 In the fourth embodiment, the distribution service fee is charged to the telephone set of the terminal 12 every time the server 16 distributes the moving image data. However, the distribution service is set according to the contents and the number of distribution conditions set by the terminal 12. The service fee may be charged to the mobile phone (telephone) of the terminal 12. However, the method of collecting the distribution service fee is not limited to the charging for the mobile phone, and for example, the moving image distributor may directly charge using a credit card or the like.

When a user selects an arbitrary distribution condition from a plurality of distribution conditions presented by the server 16 when setting a distribution condition using the terminal 12, a search for the server 16 is generally performed. Although the processing load is considered to be relatively light, if the user sets the distribution conditions independently, there is a high possibility that the ambiguous distribution conditions will be set, and if the ambiguous distribution conditions are set, the server 16 requires an ambiguous search, so the load is considered to be heavy. Therefore, if the distribution service is charged with a higher distribution service fee as the content of the distribution condition becomes more complicated or vague, a reasonable fee collection system is obtained.

As the number of distribution conditions, there are various forms such as a case where five conditions are required to be matched and a case where only one condition is satisfied. Considering the load on the server 16 side, As the number of distribution conditions increases, it becomes more difficult to search for a moving image that matches the distribution conditions. Therefore, if the higher the number of distribution conditions, the higher the distribution service fee, the more reasonable the fee collection system.

Embodiment 8 FIG. In the above fourth embodiment, the case where the delivery service fee is charged to the telephone of the terminal 12 every time the server 16 distributes the moving image data has been described. However, even if the number of times the server 16 distributes the moving image data increases or decreases, A fixed amount of distribution service fee may be charged to the mobile phone (telephone) of the terminal 12 for a certain period. However, the method of collecting the distribution service fee is not limited to the charging for the mobile phone, and for example, the moving image distributor may directly charge using a credit card or the like. For example, in the case where distribution service fees are collected on a monthly basis, a contract form in which a fixed fee is collected regardless of how many times the distribution service is used in one month can be adopted. Accordingly, a user who has a high degree of use of the distribution service can fully use the distribution service without worrying about the number of times the distribution service is used.

Embodiment 9 In the first embodiment, when setting the distribution conditions of the moving image, the Internet 11
Is set irrespective of the degree of congestion, but when a distribution request is received from many terminals 12 at once, the server 16
Therefore, the number of terminals 12 to be serviced needs to be limited.

Therefore, the setting range of the distribution condition by the terminal 12 may be changed according to the degree of congestion of the Internet 11. For example, when the Internet 11 is not congested, setting of distribution conditions for distributing moving images such as professional baseball, soccer, drama, and news programs is permitted, but when the Internet 11 is congested,
The setting of the distribution condition of the moving image related to professional baseball is rejected. This may cause the Internet 11 to move in a direction in which the congestion degree decreases.

Further, a distribution service fee according to the degree of congestion of the Internet 11 may be charged to the portable telephone (telephone) of the terminal 12. That is, if the higher the congestion degree of the Internet 11 is, the higher the distribution service fee is charged, the Internet 11 may move in a direction in which the congestion degree decreases.
