Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a video distribution system that provides viewers with video captured by a video camera or the like (digital camera) in real time.
[0002]
[Prior art]
In recent years, the general public has a large number of IT devices, and the distribution of information using the Internet has also become common.
[0003]
For example, in the video distribution system using the conventional video camera shown in FIG. 10, the encoder built-in adapter 1 is attached to the video camera 2, and the memory card 3, the wireless LAN card 4 or the wired LAN is further attached. In this description, the wireless LAN card 4 is assumed.
[0004]
For example, a wedding reception banquet hall is photographed with the video camera 2, and this video signal is transmitted via the personal computer 6 using the Internet 10 (broadband). That is, the broadband modem router 11 is used.
[0005]
Then, a user (for example, a relative) at a remote location accesses the personal computer 6 using the personal computer 9 (hereinafter referred to as a “personal computer for viewers”) to view the video captured by the video camera 2 in real time.
[0006]
In the case of using the above-described broadband, when an image is transmitted, an IP address is acquired from a broadband provider (not shown) and transmitted.
[0007]
[Problems to be solved by the invention]
However, in order for the viewer to view the photographer's video, the video stored in the server cannot be displayed on the viewer's personal computer unless the IP address of the sender's personal computer is notified by telephone or the like. .
[0008]
That is, in order to show the transmitted video, the sender must notify the IP address (dynamic IP) each time, which is troublesome.
[0009]
In addition, obtaining a fixed IP address when using broadband to save the effort is generally expensive.
[0010]
Furthermore, since the fixed IP address is assigned based on the line to which the sender's personal computer is connected, the video camera and the sender's personal computer are moved to another location and connected to the other location. When the image is taken and the image is transmitted, the same address as the previously assigned fixed IP address cannot be used.
[0011]
That is, there is a problem that, even though a high-cost fixed IP address is acquired, the fixed IP address cannot be used, so that the photographing location cannot be easily moved freely.
[0012]
In addition, if the shooting location is moved because it may be costly, a new fixed IP address must be notified to the viewer each time, so that there is a problem that it takes time to notify the IP address for each distribution. there were.
[0013]
In order to solve such a problem, a method using a server is also used.
[0014]
For example, the video distribution system shown in FIG. 9 takes a picture of a wedding reception hall with a video camera 2 and transmits this video signal via the personal computer 6 using the Internet 10 (broadband). That is, the broadband modem router 11 is used.
[0015]
Then, a user (for example, a relative) at a remote location accesses the personal computer 6 using the personal computer 9 (hereinafter referred to as a “personal computer for viewers”) to view the video captured by the video camera 2 in real time. In such a method, the problem of the IP address as shown in FIG. 10 does not occur.
[0016]
However, in the method using the server as shown in FIG. 9, the captured video is stored in the site server, and the captured video of the server is acquired using the IP address of the sender's personal computer notified of the viewer's personal computer. Since this is a method, when there are a large number of senders, access concentrates on the server, and a large load is applied.
[0017]
For this reason, since it is necessary to strengthen a network and a server, there existed a subject that cost became high.
[0018]
The present invention has been made in view of the above problems, and an object of the present invention is to obtain a video distribution system that does not increase the cost even when the shooting location is changed and does not impose a load on the network and the server.
[0019]
[Means for Solving the Problems]

DETAILED DESCRIPTION OF THE INVENTION
<Embodiment 1>
FIG. 1 is a schematic configuration diagram of a distribution system according to the first embodiment.
[0026]
In the video distribution system, the sender A first accesses the site server 11 and performs user registration. When the user registration is completed, the server logs in to the server and requests “URL with access key” for specifying the page of the sender A. The server generates a unique “URL with access key” Ui and informs the sender.
[0027]
Next, the sender notifies the viewer of the “URL with access key” Ui generated from the server together with the scheduled delivery date and time by e-mail or the like.
[0028]
When the distribution is actually started, the distributor logs in to the site server again, transmits the video shot by the video camera 2 from the sender's personal computer 10 and starts transmission to the “URL with access key” Ui. This is set in the server. The server automatically obtains the “IP address” P of the sender's personal computer at the timing of the setting, and the video source of the “URL with access key” Ui is distributed from the “IP address” P Associate.
[0029]
When the viewer accesses the “URL with access key” Ui with an Internet browser at the scheduled delivery date and time, the server of the site determines the access key of this URL and determines that the user is authorized by the sender A. At the same time, an HTML file describing that the video source is “IP address” P is returned to the viewer's browser. The viewer's browser interprets the HTML file and requests the video from the “IP address” P that is the video source. That is, the viewer can directly view the video from the personal computer 10 without going through the server 11.
[0030]
As shown in FIG. 1, the server 11 includes at least a recipient condition acquisition processing unit 15, a URL code creation processing unit 16, a reservation table creation processing unit 17, and an HTML file transmission processing unit 18.
[0031]
The receiver condition acquisition unit 15 first performs authentication by accessing from the sender's personal computer 10 and transmits screen data for setting when and what to distribute to the sender's personal computer 10. The distribution reservation data transmitted from is acquired and notified to the URL code creation processing unit 16.
[0032]
The URL code creation processing unit 16 generates a URL code based on the limited number of distribution reservation data. The created URL code is notified to the transmission terminal.
[0033]
In the URL code generation processing unit 16, the reservation table creation processing unit 17 generates a reservation table in which distribution reservation data is described.
[0034]
The sender's personal computer 10 can access the server and set distribution permission for each generated URL.
[0035]
The video source URL transmission processing unit 18 adds the IP address to the reservation table when the video distribution is notified from the sender's personal computer 10, the IP address is notified, and the video request is received from the receiver's personal computer 9, and authentication is performed. Then, the IP is embedded in the HTML file tag and transmitted to the personal computer 9 of the recipient.
[0036]
Further, the sender's personal computer 10 includes at least an IP address transmission processing unit 20 and a mailer 22 according to a program transmitted from the server 11. The personal computer 10 has a browser function and a mail function.
[0037]
The IP address transmission processing unit 20 acquires an IP address (dynamic IP address) given from the provider 12 when a connection request is made to the network 14 at the time of distribution, and transmits this IP address to the server 11.
[0038]
On the other hand, in the video camera 2, the encoder built-in adapter 1 is attached to the video camera 2, and the wireless LAN card 4 is further attached, and an IP (hereinafter referred to as “local IP”) is assigned by the personal computer 10.
[0039]
The operation of the video distribution system configured as described above will be described using the sequences of FIGS. In the present embodiment, it will be described as shooting at the wedding reception hall A.
[0040]
A photographer who operates the video camera 2 (with built-in wireless LAN) connects the sender's personal computer 10 to the network 14. In this connection, the provider 12 assigns an IP address to the sender's personal computer 10 (d1).
[0041]
Then, the sender's personal computer 10 accesses the server for authentication, receives the program, logs in, and receives the distribution reservation screen shown in FIG. 4 (d2, d3).
[0042]
This distribution reservation screen includes a title name of distribution video, a scheduled distribution date and time, a limited number of distribution, a password, and the like.
[0043]
When distributing to one person, single is selected, and in the case of many, URL issuing for the limited number of persons is selected. The sender's personal computer 10 transmits these reservation data to the server 11 (d4).
[0044]
The receiver condition acquisition unit 15 of the server 11 causes the URL creation processing unit 16 to generate a URL code based on the limited number of distribution reservation data. For example, when the limited number of people is two, the URL creation processing unit 16 generates a URL code as shown in FIG. That is, the sender side has made a distribution reservation.
[0045]
Next, the server 11 transmits a URL code based on the distribution reservation data to the sender's personal computer 10 (d5, see FIG. 6).
[0046]
In this screen, the sender inputs a predetermined item and transmits it (d6). For example, the delivery destination (recipient ID, password, etc.) is input. In addition, video screen setting data, background, and the like are input and transmitted.
[0047]
When all the settings are completed, a confirmation command is input and transmitted to the server 11 (d7).
[0048]
When the server 11 receives the confirmation command, the reservation table creation processing unit 17 generates the reservation table shown in FIG. 7 in which the URL code generated in the URL code generation processing unit 16 is associated with the user ID of the recipient. To do.
[0049]
On the other hand, the sender notifies the viewer of the generated URL, user ID, etc. using the mailer (d8). For example, a message indicating that Mr. A's wedding will be broadcast at this URL between 12:00 and 14:00 on October 1 is notified by e-mail.
[0050]
Further, the sender can access the server again and set permission / non-permission of distribution for each generated URL.
[0051]
The viewer accesses the site with the URL transmitted by e-mail, inputs the user ID, password, etc., and transmits them (d9).
[0052]
The server 11 determines whether the URL that has been accessed is permitted to be distributed to the sender. If the URL is not permitted, the server 11 is not connected. If the URL is permitted, the user ID and password of the viewer's personal computer 9 exist in the table. In this case, the corresponding URL is transmitted to the viewer's personal computer 9 (d10). In other words, authentication is performed on the server side and the receiving side, and only a recipient who is permitted in advance can obtain the stream distribution.
[0053]
The viewer uses this URL code to access the server 11 (d11) and inquires whether there is a delivery (d12).
[0054]
When the server 11 is not distributed, the server 11 transmits a preparation for distribution to the viewer's personal computer 9 (d13). In that case, the personal computer 9 makes an inquiry again.
[0055]
That is, since the viewer's personal computer can access the server with the URL transmitted by e-mail, there is no need to perform processing such as login. For this reason, the load on the server is reduced.
[0056]
When shooting of the venue starts with the video camera 2, the sender inputs transmission ON to the personal computer 10 (d16).
[0057]
When the transmission is turned on, the personal computer 10 transmits a distribution start to the server 11 and transmits an IP address at the same time (d17). The server 11 adds the sent IP address to the reservation table, transmits a transmission start (HTML, d18), the viewer's personal computer 9 RELEATs and returns reception possible (d19). An IP address is embedded in the tag of the stored HTML file and transmitted (d20).
[0058]
That is, the IP address of the video source (stream 23 of the personal computer 10) is transmitted. Next, the viewer makes a transmission request with the IP address of this video source (d21). Since this IP address is the sender's personal computer 10, the video data stream indicated by the IP address is directly sent to the viewer's personal computer 9.
[0059]
That is, since the video data is distributed from the sender's personal computer 10, the load on the server 11 is reduced.
[0060]
Further, since the distribution is inquired of the server 11 and the video distribution is received from the transmission-side personal computer, the server 11 can perform billing management for the viewer or the sender.
[0061]
Furthermore, even if the sender moves for some reason, the server 11 rewrites the reservation table with the newly sent IP address, and the viewer's personal computer with the IP address of the video source in which the new IP address is embedded in the HTML file. Therefore, even if the location is moved, the video is provided from a personal computer having a new video source IP address. For this reason, even if it moves a place, it does not cost.
[0062]
<Embodiment 2>
FIG. 8 is a schematic configuration diagram of the video distribution system according to the second embodiment. The second embodiment is a case where the video camera 30 has an Internet function and a browser function.
[0063]
When such a video camera 30 is used, an IP address (dynamic IP address) given by the provider 12 when a connection request is made to the network 14 by accessing the server 11 using the Internet function is obtained. An IP address transmission processing unit 20 that transmits an IP address to the server 11 is provided.
[0064]
That is, as in the first embodiment, the server 11 of the site creates a URL based on the conditions of the distributor, transmits the IP address assigned by the provider 12 from the video camera 30, and requests the video request from the viewer's personal computer 9. Accordingly, the URL embedded with the IP address is transmitted as the URL of the video source, and the viewer directly transmits the video captured by the video camera 30 using the URL of the video source. That is, the viewer receives real-time video distribution without going through the server.
[0065]
In the above embodiment, the wedding pattern is distributed as a video from the venue. However, the video camera and personal computer of this system are installed at the daycare center or at home and connected to the network, so that the child can work from a remote workplace. You may decide to look at a demented elderly person and a pet.
[0066]
【The invention's effect】
As described above, according to the present invention, the site server creates a URL based on the distributor condition, causes the sender terminal to transmit the dynamic IP address given by the provider, and makes a video request from the viewer terminal. Along with this, an HTML file in which the IP address is embedded is transmitted.
[0067]
Then, the viewer directly transmits the video photographed by the video camera 2 from the sender's personal computer 10 using the IP address of the video source. In other words, since the viewer receives the video distribution in real time without going through the server, an effect of reducing the load on the server is obtained.
[0068]
Even if the sender moves, the IP address is re-registered in the server, and the URL notified to the viewer is the server's URL, so the new IP address embedded in the HTML file returned from the server The viewer accesses the terminal on the transmission side using. In other words, even if the location is moved, the URL address can be used as it is, so that the cost is reduced and the viewer does not have to be aware of the IP address of the sender. Since permission / non-permission can be set, there is an effect that the sender can set which viewer is permitted to view each distribution.
