DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0007]
FIG. 1 is a system configuration diagram of an embodiment of an inter-airport moving image distribution system according to the present invention.
[0008]
In this embodiment, multicast routers A1, A2, A3, and A4 that bundle networks of New Chitose, Haneda, Osaka, and Fukuoka airports, and local videos of New Chitose, Haneda, Osaka, and Fukuoka airports, respectively. TVs C11, C12, C13, and C21, which are display devices for displaying regional images other than their own airports at New Chitose, Haneda, Osaka, and Fukuoka airports. , C22, C23, C31, C32, C33, C41, C42, and C43, and the multicast routers A1, A2, A3, and A4 are connected by a communication network such as the Internet.
[0009]
At New Chitose Airport, the video camera B1 and the televisions C11, C12, and C13 are connected to the multicast router A1 via a network (not shown) via a network to form a subnet D1, and at Haneda Airport, the video camera B2 and televisions C21, C22, and C23 are connected to a multicast router A2 via a network (not shown) via a network to form a subnet D2. In Osaka Airport, a video camera B3 and televisions C31, C32, C33 is connected to the multicast router A3 through a personal computer (not shown) to form a subnet D3. At Fukuoka Airport, the video camera B4 and the televisions C41, C42, C43 are connected to a personal computer (not shown). Via multicast router A4 It is connected by a network constituting a subnet D4.
[0010]
The multicast routers A1, A2, A3, and A4 are devices that relay moving image data that flows on the network to other networks, and correspond to multicast that designates a plurality of partners and transmits the same data.
[0011]
Video cameras B1, B2, B3, and B4 are installed at locations where each airport or nearby city of the airport can be photographed. It is preferable to do.
[0012]
Next, the operation of the present embodiment will be described in detail with reference to FIGS. FIG. 2 is a flowchart for explaining the operation of the embodiment of the inter-airport moving image distribution system according to the present invention, and FIG. 3 shows the transmission of the moving image data of the embodiment of the inter-airport moving image distribution system according to the present invention. FIG. 4 is an explanatory diagram for explaining a route, and FIG. 4 is a diagram showing a display example at Haneda Airport in the embodiment of the inter-airport moving image distribution system according to the present invention.
[0013]
An example will be described in which images from New Chitose Airport are displayed at Haneda, Osaka, and Fukuoka airports. First, in order to display the image of New Chitose, a multicast group G1 is configured by using an appropriate multicast address M1 with the video camera B1 in the subnet D1, the television C21 in the subnet D2, the television C31 in the subnet D3, and the television C41 in the subnet D4. (Step S1).
[0014]
Note that since the multicast group G1 has members extending over the subnets D1, D2, D3, and D4, a distance-vector multicast routing protocol (hereinafter referred to as DVMRP) or the like is used. By using this, the multicast packet can be passed over each multicast router A1, A2, A3, A4.
[0015]
The video camera B1 in the subnet D1 takes a picture of New Chitose Airport or the neighboring city of New Chitose Airport (step S2), and the video taken by the video camera B1 is converted into video data on a personal computer (not shown) (step S3). The converted moving image data is transmitted as a multicast packet to the multicast router A1 with the multicast address M1 (step S4).
[0016]
In the multicast router A1, since the moving image data addressed to the multicast address M1 is to be transmitted to the multicast router A2 based on DVMRP, the received moving image data is transmitted to the multicast router A2 (step S5).
[0017]
In the multicast router A2, since the moving image data addressed to the multicast address M1 is to be transmitted to the television C21 and the multicast router A3 based on DVMRP, the received moving image data is transmitted to the television C21 and the multicast router A3. (Step S6).
[0018]
Similarly, the moving image data is transmitted to the television C31 and the multicast router A4 (step S7), and is transmitted to the television C41 (step S8), whereby the moving image data is distributed to all members in the multicast group G1.
[0019]
Through the procedure described above, video shot at New Chitose will be distributed to the airports in Haneda, Osaka, and Fukuoka in real time as video data via the network. It is delivered to each airport according to the procedure.
[0020]
As described above, according to the present embodiment, by distributing moving image data over a network connecting airports, the weather information of the destination is visually provided to the user as a video, By conveying the weather information of the destination as an actual feeling, it is possible to provide a better user service and improve the ability of the airport user to attract customers.
[0021]
That is, according to the present embodiment, for example, it is more direct to the airport user to know how cold it is to see the person wearing the coat deeper than the temperature of 10 degrees. Therefore, if you travel by airplane, you can get to the destination in 1 or 2 hours, so the weather and temperature conditions at the time of departure From this, the situation at the time of arrival can be assumed.
[0022]
In this embodiment, each television C11, C12, C13, C21, C22, C23, C31, C32, C33, C41, C42, C43 has a one-to-one correspondence with the video cameras B1, B2, B3, B4 at each airport. Although compatible, each video camera B1, B2 by joining another multicast group on each TV C11, C12, C13, C21, C22, C23, C31, C32, C33, C41, C42, C43 side , B3, and B4 can be received.
[0023]
That is, when there is a multicast group G1 to which the video camera B1 of New Chitose Airport (subnet D1) belongs and a multicast group G2 to which the video camera B2 of Haneda Airport (subnet D2) belongs, the television C31 at Osaka Airport (subnet D3). By selecting whether to join the multicast group G1 or the multicast group G2 on the side, information from New Chitose Airport or Haneda Airport can be selectively displayed on one television C31.
[0024]
The multicast group may be selected by the user using an input means such as a touch panel, and the user can select the multicast group in conjunction with a device that can detect the destination of the user as information, such as a ticket issuing machine. A multicast group that can receive moving image data from the user's destination may be selected without being conscious of the destination. When linked to a ticket-issuing machine, a TV can be installed in the vicinity of the ticket-issuing machine to check weather information at the destination airport without having to specify it at the time of ticket purchase or check-in. It becomes possible.
[0025]
Note that the present invention is not limited to the above-described embodiments, and it is obvious that the embodiments can be appropriately changed within the scope of the technical idea of the present invention. In addition, the number, position, shape, and the like of the constituent members are not limited to the above-described embodiment, and can be set to a number, position, shape, and the like that are suitable for implementing the present invention. In each figure, the same numerals are given to the same component.
[0026]
【The invention's effect】
The inter-airport video distribution system and the inter-airport video distribution method of the present invention visually provide weather information of a destination to a user as a video by distributing video data over a network connecting the airports. By conveying the weather information of the destination to the user as an actual feeling, it is possible to provide a better user service and improve the ability of the airport user to attract customers.
[0027]
That is, the inter-airport video distribution system and the inter-airport video distribution method of the present invention directly convey information such as how cold it is to see a person wearing a coat deeply rather than a temperature of 10 degrees. At the time of departure, airport users want to know the destination information most quickly, and when traveling by plane, they can arrive at the destination in 1 or 2 hours in the country. From the weather and temperature conditions of the destination, it is possible to assume the situation at the time of arrival.
