TECHNICAL FIELD OF THE INVENTION
The present invention relates to a video content distribution system for a mobile device that wirelessly transmits images, advertisements, news, and the like to mobile devices such as an aircraft, a bus, and a train to provide passengers with detailed contents.
[0002]
[Prior art]
If you travel far away by transportation, you must sit for a long time. Therefore, in order to keep the passengers from getting bored even when sitting for a long time, it is widely practiced to display a movie as a service for passengers when the flight time on an international flight is long.
[0003]
For example, several movies are screened according to the boarding time. Recently, a service in which a passenger can freely select a movie by providing a liquid crystal monitor in a seat has appeared.
[0004]
The content suitable for passengers includes content adapted to the language of the passenger, the latest news video of the destination, and commercial video of products sold in the destination country.
[0005]
Most of the passengers of the aircraft are classified into tourists, business travelers, or returnees according to the airline, destination, period, and time zone. For this reason, the speaking language and audience are fairly uniform. On the other hand, it is said that sitting in a chair for a long time has a fairly high probability of seeing images, and it is said that if you play movies, sightseeing and business information, and advertisements tailored to the audience, customer satisfaction will rise considerably and the effect of advertising will be high. .
[0006]
However, airplanes, buses, and trains (hereinafter collectively referred to as mobile devices) do not always travel on the same route, but often travel on various routes. Therefore, it is necessary to change the content to be shown in the machine each time (by manually replacing a recording medium such as a video tape or a DVD).
[0007]
On the other hand, there is also a system in which a mobile device receives the latest news of a passenger or a video of a live sports event in real time and distributes it to the passenger (for example, Patent Document 1).
[0008]
[Patent Document 1]
JP 2001-503947 A
[Problems to be solved by the invention]

[0012]
In addition, in selecting the video content, the user has to select the appropriate language desired by the passengers of the mobile device according to the destination, period, time zone, etc. of the mobile device. In addition, movies were chosen to end within the time of arrival at the destination.
[0013]
On the other hand, news is news distributed by a specific broadcasting station, and tourist information is a sightseeing route created by a specific trader.
[0014]
However, for passengers who have visited the site many times for sightseeing, business, etc., they often provide more interesting information.
[0015]
That is, there has been a problem that the delivery of the video content to the passenger of the conventional mobile device does not deliver the detailed video content.
[0016]

[0047]
Optical communication is a transmission method suitable for aircraft since it has no radio wave interference, is non-contact, and has high confidentiality. At this time, a compression technique such as MPEG may be used.
[0048]
In addition, tuners are constantly receiving news from around the world via satellite and updating television programs in the database to the latest.
[0049]
(Operation explanation)
The operation of the mobile device video content distribution system configured as described above will be described below using the sequence of FIG.
[0050]
When the door of the aircraft 1 is opened after the boarding gate 12 is adhered to the door of the aircraft 1, when the in-flight optical transceiver 14 of the aircraft 1 and the optical transceiver 13 of the boarding gate 12 are depressed by the start switch 19, Perform optical axis alignment.
[0051]
Then, the passenger aircraft content distribution server 3 of the video distribution site 8 transmits a start signal via the optical transceiver 13 (d1).
[0052]
Next, the passenger aircraft content distribution server 3 of the video distribution site 8 transmits an ID request signal (d2), and the passenger video distribution server 2 authenticates whether the ID request signal is correct with the reception of the ID request signal, When the authentication result is "OK", the unique ID registered in advance is transmitted (d3).
[0053]
After receiving and authenticating the unique ID from the optical transceiver 13, the passenger aircraft content distribution server 3 of the video distribution site 8 transmits an operation information request to the in-flight optical transceiver 14 via the optical transceiver 13 (d <b> 4). ).
[0054]
The passenger video distribution server 2 in the aircraft 1 reads out the operation information A2i stored in the database 24 and transmits it via the optical transceiver 13 (d5).
[0055]
Upon receiving the operation information A2i from the passenger video distribution server 2, the passenger aircraft video distribution server 3 of the airport building determines the tendency of the customer base based on the operation information A2i, and extracts the optimal passenger video content ( d6), and transmit (d7).
[0056]
For example, it is known that, depending on a departure place, an arrival place, a departure day, and a time zone, what kind of required language is good and what kind of content is good show a certain tendency. For this reason, in the present embodiment, the operation information A2i is used as a parameter, a tendency that matches the parameter is calculated, and operation information that matches the calculated tendency is extracted.
[0057]
Although not shown in the present embodiment, the boarding reception server may be accessed to extract the customer layer of the passenger list of the boarding flight, and to extract the tendency of adding this customer layer to the above-described parameters.
[0058]
Next, the passenger content extracting unit 27 extracts, from the database server 4, optimal passenger aircraft video content corresponding to the passenger tendency determined by the operation information determining unit 26.
[0059]
At the time of this extraction, a movie shorter than the boarding time is first set as a first candidate. Then, for example, two movies that match the language of the airport country are further selected from the first candidates. Next, two movies in the language of the destination country are selected from the first candidates. Then, one movie in the language of the country of the airline is selected from the first candidate movies. Of course, if each language is busy, the number of movies selected in another language may be increased.
[0060]
Next, a commercial image is selected. First, two commercial videos whose destination country and registered distribution country name match are selected. Next, for example, two commercial videos in which the country of the airline and the registered distribution country match are selected.
[0061]
Then select the news. News selects the news of the destination country. This news has been updated to the latest. Thus, the content to be transmitted is determined.
[0062]
Therefore, the movie is stored in the distribution server of the aircraft in accordance with the language of the airport, the language of the destination country, and the language of the airline company. Therefore, most passengers can select a movie in a language suitable for themselves. In addition, since the distribution server can store many types of movies in the same language, passengers can select from many movies.
[0063]
In addition, because news is received from the storage server at the airport, the latest news in the destination country immediately before departure can be viewed. Also, there is no need to provide a news receiving system on the aircraft.
[0064]
In addition, since the commercial requesting company receives commercials on the most efficient aircraft, advertising efficiency is high. Further, since the advertisement fee is paid based on the number of times of actual transmission, there is no waste in cost.
[0065]
Further, it is not necessary to accumulate a large number of movies in the storage device of the aircraft, so that the storage capacity can be reduced and the cost can be reduced.
[0066]
Next, the content distribution unit 28 transmits the passenger video content A2i to the optical transceiver 13 provided in the boarding gate 12 via the interface 11. That is, the video content is not manually carried into the aircraft. In addition, since the communication speed is 100 Mbps and 1 Gbps, and the content is distributed in the airplane, the content corresponding to the customer layer is distributed in a short time.
[0067]
On the other hand, the passenger video distribution server 2 in the aircraft 1 receives the passenger video content A2i and stores it in the database (d8). Then, an error check is performed (d9), and if there is no error, an end signal is transmitted to the passenger aircraft content distribution server 3 via the in-flight optical transceiver 13 and the optical transceiver 14 (d10).
[0068]
On the other hand, the passenger aircraft content distribution server 3 updates the data of the advertisement billing for the advertiser (d11). For example, during periods of congestion in August, the advertising billing fee is increased, and during periods of no congestion, the fee is reduced.
[0069]
Then, billing data is charged to the advertiser according to the number of distributions of the advertisement (d12).
[0070]
On the other hand, the passenger video distribution server 2 deletes all the old contents which are real-time information such as news in the database server 4 and saves the newly transmitted contents.
[0071]
(In-flight operation)
When the aircraft 1 departs and reaches a safe altitude, video distribution is started. The passenger operates the passenger terminal 16 in each seat to select content such as a movie or news and requests distribution.
[0072]
The passenger video distribution server 2 distributes the requested content to the passenger terminal 16. The distributed content is reproduced on the monitor.
[0073]
For example, as shown in FIG. 5, a menu screen is displayed on the monitor, from which the passenger selects desired content. FIG. 5 shows that the content is provided in English and Japanese.
[0074]
In particular, local information is information provided by the local information provider on the Internet prior to boarding, providing information on the status of sightseeing spots, pitfalls, and the status of athletes. Therefore, the passenger can obtain detailed information in advance.
[0075]
【The invention's effect】
As described above, according to the present invention, even if the video content is not manually replaced according to the route of the mobile device, when the mobile device is bonded to the gate of the boarding building, the destination of the mobile device, the passenger layer, The corresponding content is automatically transmitted from the video distribution terminal system in the boarding building to the passenger video terminal distribution system by light communication.
[0076]
That is, there is obtained an effect that contents corresponding to a passenger class can be provided in a short time without affecting the equipment of the mobile device and at a reduced cost.
[0077]
Further, the latest information on the site is collected by the web server, and when the mobile device is bonded to the gate of the boarding building, it is automatically transmitted to the passenger video terminal distribution system by light communication, which is further interesting. The effect is that information can be provided to passengers. Commercial advertisers are also more efficient in advertising and less costly.
