Description

  The present invention relates to an information transmission system using regional limited broadcasting (area broadcasting) by a general radio wave system such as terrestrial digital broadcasting waves.

Conventionally, facilities such as amusement parks have provided many services such as rides, events, restaurants, etc., and the congestion, fullness information, and waiting time information for each service provided is located near the entrance for each service provided. Or by oral communication by employees.
According to this method, visitors can obtain such information near the entrance of each service.

  However, in this method, it is necessary for the visitor to move to each provided service and check by checking the bulletin board or by checking with an employee in the vicinity. If it is desired to be prioritized, it is necessary to move and check one place at a time, so there is a problem that enormous time and labor are required, and it is extremely difficult to select and compare the entire situation.

In addition, since the visitors can only know fragmentary information, there is a problem of unevenness of congestion, leading to an increase in the burden on employees such as guidance of visitors and an increase in operating costs.
Further, as a technique related to the present invention, an electronic guidance information processing system that transmits real-time information (such as waiting time information for attractions that change from moment to moment) from a wireless broadcasting means in a theme park is known (see Patent Document 1).

In addition, a parking waiting time guidance system that detects arrival characteristic information by image processing and predicts waiting time based on visit characteristic information detected in the past (that is, by learning) is known (see Patent Document 2).
Also, assuming that you are acting with a lost child search requester (for example, a parent) before the lost child is lost, when you are requested to search for a lost child, based on the video of the lost child search requester There is known a lost child search / monitoring system that authenticates the person, searches the record information, and searches for a lost child that has been requested for retrieval in relation to the client (see Patent Document 3).

FIG. 1 is an overall configuration diagram of an information transmission system according to an embodiment of the present invention. The information transmission system 1 in FIG. 1 shows a configuration example when an optical fiber is used as a wired transmission path, and is basically the same as that called “area one seg” (area limited one seg).
The server S processes and accumulates information on various locations providing services in real time, and refers to an attraction database (attraction DB) to generate information data (mostly text data) to be provided as a program. Information on each location includes, for example, human sensor signals installed at predetermined intervals along the queue of people waiting, the number of tickets issued (including those issued electronically), and actual entry to the attractions. The number of counters of the number of people who were able to do, etc. The attraction DB stores the capacity of each attraction (number of people who can enter per unit time) and the like. An existing server (DB) that manages event information, a server that collects lost child / lost article information, and the like can also form part of the server S. A configuration may be provided in which a program having a predetermined content is stored in advance, such as for evacuation guidance in a large-scale disaster.

  The program editing device 2 automatically edits information data from the server S into a program. In the present embodiment, there are six programs as will be described later, and each program is composed of a video signal, an audio signal, caption data, BML content, and the like, which together with the program identification information (PSI) are ARIB STD- In accordance with the regulations such as B32, TS is once multiplexed for each program. These six TS streams are multiplexed as necessary, encapsulated in a DVB-ASI interface or IP packet, and output through an Ethernet (registered trademark) interface.

The transmission device 3 converts the TS stream input from the program editing device 2 into a terrestrial digital television broadcast wave (ISDB-T system) or a terrestrial digital radio broadcast wave (ISDB-T) for portable terminals in accordance with the regulations of ARIB STD-B31 and the like. SB system) signal (high frequency signal). That the OFDM segment of bandwidth (referred to as one-segment physical channel) multiple 6/14 MHz (about 429 k Hz) using a (preferably 13 or less) pieces linked bands (physical channel), and transmits the 6 programs.

  Thereafter, the channel waveform shaping and level balance are appropriately adjusted and supplied by the head amplifier 4. Further, it is converted into an analog modulated optical signal by an E / O (Electronic Optical) converter 5 and supplied to a plurality of transmission lines 7 by an optical distributor 6. In various places where the service is provided, this is converted into a high-frequency signal by an O / E (Optical Electronic) converter 8, amplified by a power amplifier 9, and transmitted from a transmitting antenna 10. Visitors can receive information by setting digital terrestrial broadcast waves in a receiving state using a mobile terminal and selecting a dedicated channel.

  FIG. 2 shows an example of the configuration of the information providing area. The information providing area is configured as a plurality of blocks corresponding to the classification (district, zone) in the facility. In FIG. 2, one transmission antenna is shown for each block. However, since the same broadcast wave signal is transmitted from all the transmission antennas, the installation position of the transmission antenna may be irrelevant to the block. Instead, each block will be equipped with a sign that can recognize which block the visitor is in, and a short-range communication device that transmits block information.

FIG. 3 is an internal configuration diagram of the program editing apparatus 2.
A network interface (net I / F) 101 is an I / F for connecting to an in-facility LAN or the Internet, and realizes communication (socket communication) with the server S.
The electronic speech API 102 is an application programming interface for accessing an electronic speech server on the Internet, and is, for example, Twitter (registered trademark) API. The electronic utterance API 102 logs in to the electronic utterance server with a user name such as a facility operator (a plurality may be provided for each attraction), and periodically acquires a timeline (list of past utterances).

  The program generation unit 103 is application software that performs overall control of the program editing device 2, sorts text information such as fullness information and waiting time acquired from the server S, and at a timing according to the program configuration. Expand to the caption device 105 and the like. In addition, a program produced by another program editing device or the like is acquired via a network and developed on the caption device 105 or the like.

  The subtitle device 105 is a device that generates each screen (moving image) shown in FIGS. 6 to 8, and draws text information and the like from the program generation unit 103 as a table, and scrolls depending on an instruction while changing the screen size. = 320 × 240 (or 320 × 180), about 15 frames / second of video is output. As a feature of the present embodiment, the scrolling speed is fixed to 1 pixel / frame, and a signal indicating that (scroll amount signal) is separately output during scrolling.

The speech synthesizer 107 reads out the text output as caption data from the program generator 103 with synthesized speech and outputs it as an audio signal. The caption PES conversion unit 104 converts the caption data from the program generation unit 103 into a PES packet and outputs the PES packet.
The BML generation unit 109 generates BML (Broadcast Markup Language) content that can be viewed (displayed) together with the program moving image on the mobile terminal based on the text information from the program generation unit 103, and generates the DML-CC data carousel (BSM). And event message). BML basically conforms to the data broadcasting operation specification C profile. The contents are electronic utterances acquired by the electronic utterance API 102, vehicle information similar to the screen drawn by the caption device 105, and the like, assuming that these are displayed on a data broadcast virtual plane of 480 × 240 pixels. BML.

The storage unit 111 stores original data (GIF file) of content, and provides the original data to the BML generation unit 109.
H. The H.264 encoder 106 encodes the video signal from the caption device 105 in real time as much as possible in accordance with ARIB STD-B32 Part 1 Appendix 3 “MPEG-4 AVC Standard Operation Guidelines for Low-Resolution Video Services”, and further converts it into a PES packet. Output. The output bit rate is about 200 kbps even at the peak. As a feature of the present embodiment, the operation of the encoder is constrained as follows in order to simplify the decoding process in the portable terminal to the limit.
First constraint: When there is no scrolling signal, all P pictures (P slices) other than a predetermined number of P pictures following the IDR picture are skipped.
Second constraint: When motion compensation is performed with a P picture, the unit is fixed to 16 × 16 pixels.
Third constraint: When there is no scrolling signal, the motion vector is fixed at 0, and when there is the signal, it is fixed at 1 (downward).
Fourth restriction: A deblocking filter is not used.
Fifth constraint: In the 4 × 4 intra prediction (I4MB), the prediction modes 6 to 8 are not used or used as much as possible.

With respect to the first constraint described above, since the prediction residual cannot be completely encoded only by the IDR picture, a predetermined number (about 0 to 3) of P pictures is left.
Regarding the fifth constraint described above, the deblocking filter blurs block noise and is not used because it has almost no effect of making unclear characters clear.
By constraining in this way, the actual number of encoded (decoded) frames is reduced to about 1/10 at the time of a still image, and an in-loop filter that occupies almost half of the decoding process can be eliminated even at the time of scrolling.

The MPEG2 AAC encoder 108 encodes the audio signal from the audio synthesizer 107 in real time as much as possible, further converts it into a PES packet and outputs it.
The carousel transmission unit 110 buffers the carousel data written from the BML generation unit, and sequentially outputs the data in sections.
The PSI / independent PES generation unit 112 generates PSI / SI (Program Specific Information / Service Information), independent PES (time stamp, etc.), and outputs the PSI / SI after sectioning.
TS multiplexing section 113 includes subtitle PES converting section 104, H.264 The outputs of the H.264 encoder 106, the MPEG2 AAC encoder 108, the carousel transmission unit 110, and the PSI / independent PES generation unit 112 are multiplexed into a 188-byte TS packet and output as a TS. Note that at timings other than IDR pictures, H.264 is used. The bit rate from the H.264 encoder 106 is very small. In the transmission apparatus 3 that has received the TS from the TS multiplexing unit 113, when the TS cannot be received at a predetermined timing, an empty transmission TSP (a 204-byte TS packet defined by the ARIB STD-B31 transmission system) is transmitted. Is supposed to be inserted.

  The TS interface unit 114 is an interface for outputting the TS from the TS multiplexing unit 113 to the transmission apparatus 3, and packetizes the TS as a stream in accordance with RFC3954, or considers the TS as a file in a predetermined unit and performs FTP, etc. IP transmission may be used, and DVB-ASI, DVB-SPI, etc., which are common in broadcasting equipment, may be used.

As described above, in the present embodiment, the program video characteristics are used to encode and broadcast so that the decoding process can be reduced, so that the risk of running out of the battery due to program viewing is reduced and the audience can watch with peace of mind. .
Moreover, information from the viewpoint of the visitor can be obtained by broadcasting the electronic utterance included in the data broadcast. Note that it is arbitrary how the data broadcasting virtual plane, the video virtual plane, and the caption virtual plane are arranged on the screen (display area) in the mobile terminal 9, and the data broadcasting virtual plane is arranged on a large part of the screen. In addition, vehicle information and the like can be seen with a clear display.

  FIG. 4 is a configuration diagram around the server unit of the information transmission system of this embodiment. Each device to be described later is connected via a local area LAN so that they can communicate with each other. The ticketing / admission management server 201 is a server for grasping the reservation status and ticketing status of an admission ticket to an amusement park and grasping the admission status by the ticket issued. The admission ticket is, for example, an RF-ID tag, and a unique ID is attached to each ticket. The ticket issuing / admission management server 201 manages the admission status based on the ID, or performs various processes in association with other information. .

  The entrance / exit gate 202 reads the IDs of the admission tickets held by the visitors (customers) and the exits, notifies the ticketing / admission management server 201 and opens / closes the gate based on the response from the ticketing / admission management server 201. To control. The attraction gate 204 is installed for each user and general customer for each attraction, reads the ID of the customer's admission ticket before entering the attraction, notifies the ticketing / admission management server 201, and issues the ticketing / admission management server 201. In accordance with the response from the user, a predetermined display is performed.

  One or more IP cameras 205 are installed in each attraction, restaurant, resting place, entrance / exit gate, parking lot, and the like, take images of them, compress them, and send them out. The image processing device 206 receives the compressed video from the IP camera 205 and detects the congestion state of the customers, the number of people in the queue, and the like by image recognition processing.

The server S corresponds to the server S of FIG. 1 and mainly performs the following processing in this embodiment.
First processing: From the information (number of reservations, the number of actual park attendants) from the ticketing / admission management server 201, the weather conditions acquired from the outside, the calendar, the congestion status information from the image processing device 206, and the past statistical database, Predict changes in the number of visitors on that day by hour. The forecast is updated regularly, and the database is also updated according to the actual number of visitors.
Second process: Based on the predicted number of visitors and the amusement park capacity, an appropriate value of the number of attractions to be recommended to the visitors is calculated.
Third process: Based on the appropriate number of attractions, a plurality of model plans are generated and provided to the park attendant, and the provision status is managed. The model plan describes the attractions to be boarded from the current time to the closing time, and the set times thereof, and the provision status is managed for each admission ticket ID of the provided customer.
Fourth processing: Based on the current crowded status of general customers and users such as each attraction, and the plan provision status, etc. Predict for each. This is done in the same way as the number of visitors. As a result, the model plan is modified or changed depending on the attraction waiting situation. In addition, each attraction will be notified of the desired ratio of general customers and users per performance.
Fifth process: Based on the model plan provision status, a notification is given to each user a predetermined time before the set time. In addition, since the actual passing time of the attraction gate 204 deviates from the time in the model plan, the following plan is corrected (customized) for each customer and provided.

  FIG. 5 shows an embodiment of transmission information, which is divided into two information sections, total area information and block information, and provides vehicle information, restaurant information, and general guidance information, respectively. 6 1 channel is assigned to 1 segment, and this is realized using a technique of bundling these and transmitting 6 segments, or 1 channel (called subchannel) is assigned per 1/2 or 1/3 segment, for a total of 3 Alternatively, it is realized by using a technique of bundling and transmitting two segments.

  The portable terminal 9 needs to be able to tune a physical channel for the segment configured as described above, and to extract and play a TS stream of a desired program (referred to as multi-segment correspondence). If necessary, it is possible to equalize the provision of information by lending terminals dedicated to in-facility channels. This lending terminal may be driven by a fuel cell that cannot be refueled unless it is a special instrument, for example.

  Further, by adopting a narrow area configuration for each block, it is possible to receive information on the entire area, and if a visitor receives block information, it is possible to immediately receive information on the neighborhood where it is currently located. That is, the block information also includes channel setting information, and when it is received by a QR code (registered trademark) reader or a communication function of Felica (registered trademark), the one-segment tuner is automatically activated (semi-) Tune to the specified channel.

  FIG. 6 is an example of a vehicle information screen display. The screen in FIG. 6 is for the whole area information (indicated in the figure as “wide area broadcast”). For the vehicle in the facility as a whole, the vehicle name and position on the map (district map number), waiting time, Information on the issuance time of the priority boarding pass is displayed in a predetermined sequence, for example, in the order of waiting time. The district map number Aiu ... has a one-to-one correspondence with the block.

  FIG. 7 shows an example of a screen display of restaurant information, where the store name and provided contents, the position on the map, full information, and waiting time information in the case of full seats are displayed. FIG. 8 shows an example of the screen display of general guidance information. In addition to displaying the event holding status and time, the position on the map, other precautions, etc., the lost / lost information and the storage location, the position on the map Is displayed.

These screen displays are displayed by real-time scrolling or scheduled scrolling when the amount of information is large.
As for the intra-block information, the same information as the entire area information is sorted in order of waiting time for each block and displayed as independent information for each block. If the user performs an operation or the like for designating the block in which the user is present on the portable terminal, only the information of the designated block is repeatedly displayed.

(First embodiment)
This embodiment explains one form of the information transmission system which added the function which provides planning, such as an attraction, to a visitor in an amusement park, The structure of a transmission part demonstrated the information transmission of FIG. 1 demonstrated previously. It is the same as the system.
In amusement parks, customers tend to always queue up somewhere, trying to enjoy more attractions. As a result, the waiting time becomes longer, and much of the admission time is spent queuing or looking for attractions with a short queue.

  In this embodiment, it guarantees that it is possible to ride even if it is not lined up, shortens waiting time by guiding customers not to line up, and customer satisfaction by increasing free action time in the amusement park accordingly. The goal is to increase the capacity of the amusement park to the maximum by spreading the density of customers within the amusement park.

In this embodiment, in order to simplify the description, it is assumed that all attractions are vehicles, and using the attractions is referred to as “boarding”. Customers who use the planning of this system are called users, and customers who do not use it are called general customers.
Next, the operation of the information transmission system of the present embodiment will be described with a focus on one user A, using the flowchart of FIG.

  [Step S1] The admission ticket has an input unit that allows a customer to input a reservation number, a contractor number, etc., and when the reservation number is input, the admission ticket is entered into the ticketing / admission management server 201. Inquire and collate and issue a ticket. The admission ticket may be a part of the admission ticket ID converted into a number (character) or a character string that can be collated with the admission ticket ID (for example, a character string obtained by URL-encoding the admission ticket ID with a one-way function process) ) Is printed in whole or in part. It is desirable that the numbers and character strings to be printed are prepared for an operation in which a group customer desires the same plan, and are random and have the number of digits necessary to identify each individual visitor on that day.

When the reservation number or the like is not input, the same as above, but it is also preferable to print a two-dimensional barcode representing the URI of the server S including the collable character string on the admission ticket.
[Step S2] When the customer A enters from the entrance / exit gate 202, the ticketing / entry management server 201 increases the number of actually attending persons who are grasped by one. The ticketing / admission management server 201 records the actual number of visitors on that day in minutes.

  [Step S3] Before and after the entrance of the customer A, the mobile terminal of the customer A performs (indirect) access to the server S via the mobile phone packet communication network. The purpose of this is to acquire an identifier for the server S to identify the portable terminal of the user A, and to notify the portable terminal of the one-segment channel broadcasted by the information transmission system of this embodiment. It is to start. As the terminal identifier, information in the X-DCM GUID header or the X-UP-SUBNO header of the HTTP request can be used.

The portable terminal accesses the server S using a two-dimensional barcode reading function. Alternatively, after accessing the well-known home page of the server S, the printed collable characters may be directly input.
The server S inquires the ticketing / admission management server 201 for the validity of the admission ticket ID (whether it is within the validity period from the ticketing time, etc.) as appropriate, and ignores the request from the mobile terminal if it is invalid. For example, a page (HTML or BML) including the media activation description is sent to the portable terminal. If BML conforming to C profile is used for this page, it becomes C profile linked content or non-linked content. The mobile terminal that has received this activates the tuner by a user operation or automatically, and tunes to the physical channel described in the media activation description.

  [Step S4] The server S also transmits a page (HTML) for requesting transmission of a mail address or transmission of (empty) mail to the mobile terminal. The mobile terminal transmits in response. If the e-mail address corresponding to the terminal identifier is known by prior reservation, this step S4 is not performed.

  [Step S5] The server S temporarily stores the information obtained in steps S2 to S3 in the customer DB. The customer DB holds the terminal identifier, e-mail address, plan data, unsuccessful plan information, actual plan time data, notification identification information, etc. using the admission ticket ID as a key. The admission ticket ID and the terminal identifier do not have to be one-to-one, and a plurality of customers may share one portable terminal.

  [Step S6] The server S performs a process corresponding to the first process described above. In other words, data close to the weather situation acquired from the outside, the calendar, the transition of the number of visitors to the day (actual result) acquired from the ticketing / admission management server 201 is searched from the past statistics DB. In the past statistics DB, all past business days or typical changes in the number of visitors are held together with weather conditions, calendars, and the like. The data found by the search does not exactly match the actual number of visitors on the day, so it is corrected by the ratio of the number of visitors to the actual number of visitors in the search data, as well as congestion status information such as the number of reservations and parking lots. By correcting the search data in consideration of the effect of the campaign, etc., it can be used as a transition of the predicted number of visitors on the day.

  [Step S7] The server S performs a process corresponding to the second process described above. In the simplest model, the total number of passengers per unit time for each attraction is the amusement park capacity, (average value of the number of visitors since the current day) x (business hours since the current day) ÷ amusement park The appropriate number of attractions is calculated based on the capacity.

[Step S8] The server S performs a process corresponding to the third process described above. The total number of permutations is _n P _m , where n is the total number of attractions in the amusement park, and m (m is an integer less than n), and the number m of boarding attractions depends on the user's preference. Is enormous, and it is impractical to simulate all combinations that select a predetermined number of model plans from these total numbers.

Therefore, a model candidate group whose total number is reduced to about several thousand is prepared for each m. This model candidate group G _m also considers past customer trends so that the orthogonality of each model included (the attractions assigned by model A and the attractions assigned by model B do not overlap at the same time) becomes high. While designing. As a result, similar (redundant) models are deceived, and models with many popular attractions tend to be gathered in a small m model candidate group.

  Then, based on the congestion status information, the weather, and the model provision status on the day, model plans of several hundred to several thousand patterns to be provided from the model candidate group are determined. These model plans are based on conditions such as desired attraction multiplier, desired required attraction, age group, gender, walking speed (amount of walking), stimulation to the semicircular canal, weather conditions, etc. (all of these are not required) ), The models are selected while confirming that the customers are not extremely concentrated on a specific attraction by simulating the situation where each model is used by the customers with the assumed popularity. The server S transmits information on this model plan (including ID etc. that can identify each model) to the program editing device 2, and the program editing device 2 edits it into BML content of one module. As an example, steps S6 to S8 are performed every 5 minutes, and the provided model plan is also periodically updated every 10 minutes.

  [Step S9] The mobile terminal views the one-segment broadcast of the designated physical channel by using the tuner function activated in step S3. One-segment broadcasting includes the BML contents of the model group created in step S8, and the user can arrive at a suitable model plan narrowed down to several by simply answering the question corresponding to the above conditions. The model group BML content has a large capacity of several MB or more, but once received, an immediate response can be obtained to operations such as changing conditions without communicating with the server. Very good. The BML content includes information such as the expiration date and the start time of the next content (program) updated every 10 minutes. Once the module is received, the tuner other than the display until the next start time is displayed. The function can be turned off. Such an operation can be realized by using an extension function for broadcasting (Browser pseudo object method) that can be used in ECMAScript of BML content, or an event message.

  [Step S10] The mobile terminal transmits the model plan information (model ID) selected by the customer A to the server S by the packet communication function of the mobile terminal. A broadcasting extension function can be used to start this communication function. One or more model IDs may be sent, and there may be a plurality of priority IDs. One or more collation-ready character strings or two-dimensional barcode reading results printed on a companion admission ticket are designated. These companions can also send a notification that they have selected the same model plan.

  [Step S11] Upon receiving the selected model plan information in step S10, the server S collates with the customer DB whether there is a matching terminal identifier, whether the plan data is empty (not selected), or the like. To check. If there is no abnormality in the check and the selected model ID is valid, a time schedule corresponding to the model plan is generated and provided to the mobile terminal in HTML or e-mail format, and the plan data is stored in the customer DB. Save as.

  The time schedule is generated as a minute-by-minute schedule for each customer based on the attraction wait state transition (particularly waiting time) obtained in the fourth process. Also, unique notification identification information that can identify individual notifications is generated and stored in the customer DB. Along with the time schedule, the mobile terminal is also notified of a URI (including notification identification information) such as a Web page (provided by the server S) that accepts a change in the time schedule. The storage of the plan data and notification identification information in the customer DB may be performed after confirming the successful provision (transmission).

  On the other hand, in the case of a check abnormality or invalid model ID, a predetermined response (for example, guidance on the change reception page) is made. In particular, when plan data is already stored in the customer DB, it is handled as a plan change, but in order to limit the number of plan changes, the change history is added to the request unsuccessful plan information. Further, when the selection of a specific model plan is extremely concentrated, the request is unsuccessful and is added to the request unsuccessful plan information.

  [Step S12] The server S performs a process corresponding to the above-described fourth process every five minutes as in steps S6 to S8. The waiting state transition of general customers can be performed in the same manner as the prediction of the number of visitors. For example, in the past statistics DB, not only the number of visitors but also the waiting state transition of each attraction is held, and the congestion status information (the length of the matrix) actually detected by the image processing apparatus 206 is obtained from the search. , Waiting time) and slightly corrected.

  On the other hand, the waiting state transition of the user is obtained by totaling the time schedules of all the users in the user DB. For example, for all passengers whose (next) attraction after a certain reference time is A1, the average of the time from the reference time to the boarding schedule or set time on the time schedule is an estimate of the attraction A1 at that reference time It is waiting time. That is, in this embodiment, the waiting state transition of the user means the state of the user who is acting according to the time schedule at an arbitrary place, not waiting in line.

  However, in the case where only the customer column becomes longer than expected at a specific attraction A2, congestion status information is also detected in the customer column and reflected in the model candidate selection in step S8 (A2 is most recently added). In addition, the schedule of a customer who is scheduled for A2 in the near future may be delayed (described later).

  [Step S13] The following steps S13 to S16 substantially correspond to the fifth process and are repeated according to the plan data. The server S monitors each plan data stored in the customer DB in units of one minute, and sends a notification email to the email address of the corresponding customer A a predetermined time before the most recent schedule (set time) in the future. Send.

  [Step S14] Based on the provided plan data (time schedule), the user goes to the first attraction A1 and is lined up in a dedicated line for the user. The attraction gates 204 are respectively installed at predetermined positions in the customer-specific row and the general customer row so that the customers in the row can pass by the number of persons or the ratio notified by the fourth process of the server S. To do.

When the line advances and the user A reaches the attraction gate 204, the admission ticket of the user A is read and notified to the server S as passage information.
[Step S15] The server S refers to the plan data of the customer DB by using the user ID of the received passing information. If the attraction A1 does not match the latest attraction in the plan, or if the passing time is the first from the plan. If the waiting time of a general customer at attraction A1 is longer than a predetermined time (for example, 30 minutes) and longer than the second predetermined time (for example, 90 minutes), the user is not permitted to pass the attraction gate 204. A signal is transmitted to the attraction gate 204, and the passage information is additionally written in the plan actual time data together with the disapproval. At this timing, whether the fairness is not impaired even if this customer's schedule is accelerated is judged in consideration of the congestion status and waiting state transition of each attraction. Send a notification email to the customer including a later schedule.

  In other cases, a signal allowing the passage is transmitted to the attraction gate 204, the passage information is added to the plan actual time data, and the subsequent schedule is corrected earlier or later depending on the actual passage time. Regarding the amount of correction, the fairness of users and general customers is considered. As a fairness, a method can be considered in which the schedule is not corrected ahead of time when the number of unauthorized passage information recordings reaches a predetermined number.

As described above, in this embodiment, as long as the gathering is delayed from the plan, as long as the attraction remains unmodified in the plan, the user can board the attraction.
[Step S16] When the attraction gate 204 receives a signal indicating that passage is not permitted, the attraction gate 204 performs predetermined operations such as display, ringing, and closing of the gate. In response to this, the staff member, for example, guides the customer who has received the signal to rearrange the signal in the customer row. If corrections are made to speed up the schedule, customers can receive notification emails and understand the situation. As described above, in this embodiment, the automatic correction of the schedule is performed when there is a change in the behavior of each user (passing through the attraction gate 204, etc.). There is no automatic correction. Also, there is no particular management of passengers after boarding.

Here, the description will be continued on the assumption that the Web page that accepts the change of the time schedule mentioned in step S11 is used.
[Step S17] The mobile terminal accesses the server S using the packet communication function based on the URI described in the notification mail received in step S11 or S15.

  [Step S18] The server S collates the notification identification information, terminal identifier, etc. included in the request from the portable terminal with the customer DB. If a matching customer ID is found, the time schedule of the plan data of the customer ID is read, and data of a Web page that displays the time schedule in an operable manner is transmitted to the portable terminal.

  [Step S19] The mobile terminal displays the received Web page, accepts an operation from the user, and finally transmits the result to the server S. As an example of the operation, an operation in which one attraction is selected from the time schedule after the present time and changed to another attraction can be considered. As a method of selecting the attraction to be changed, a conceivable method may be a lottery method for crowded attractions or a requirement to cancel other attractions in the time schedule.

[Step S20] The server S determines whether or not the change is possible based on the congestion status information and the like, and if possible, changes the plan data of the customer and saves it in the customer DB, and changes to the customer. Send a notification email to that effect.
Among the steps described above, what needs to be considered in terms of security is the handling of use registration using collable characters printed on the admission ticket. In other words, before the customer himself / herself registers, it is necessary for the third party to be able to register as a customer by impersonating the collable characters. As an example, an upper limit is set for unauthorized registration attempts from terminals with the same terminal identifier (although the characters that can be collated will be long), and the collation power of characters that can be collated (the average number of trials to reach a valid value) There is a way to make it sufficiently higher than the upper limit. In addition, the server S sends a random number and a location information acquisition request such as GPS to the portable terminal before registration, and the random number and the location information corresponding to the amusement park are sent back from the portable terminal within a predetermined time. Registration may be permitted. The position information acquisition request uses a method prescribed by X_DPA_getCurPos () when supplied from the system by BML, and a method prescribed by each communication carrier when making a request from the packet communication network.

(Second Embodiment)
The information transmission system of the present embodiment adds an advertisement PES generation unit (not shown) to the system of the above-described embodiment, supplies the output to the TS multiplexing unit 113 of FIG. 3, and performs digital signage as well. Is. That is, the advertisement PES generation unit converts a high-definition JPEG or PNG image file, a Flash file that is an animation format of Adobe Corporation, etc. into PES, and outputs the PES. At this time, a secret stream ID (which cannot be traced from PSI / SI) is used, and the bit rate is sufficiently suppressed. The TS multiplexer 113 also multiplexes the PES output from the advertisement PES generator.

  The large display terminal is a display device equipped with a one-segment tuner or the like. If a physical channel or the above-described secret PES is specified, a transmitted image or the like can be reproduced and displayed on a liquid crystal screen or electronic paper. . Since it is considered that the reception environment at the large display terminal is stable, PES multiplex transmission is used in this embodiment, but a carousel transmission system may be used.

(Third embodiment)
The information transmission system of the present embodiment uses the system of the second embodiment for safety confirmation at the time of disaster. The server S holds HTML of a screen for accepting registration of a cellular phone number or the like of a close relative (inquirer) who cannot be contacted, and outputs it to the program editing apparatus 2 at the time of a disaster, and this system as BML content Broadcast from. In addition to the telephone number, the information to be registered is basically the information of the asker, such as a name, a rough address, a face photo, etc. However, the information of the registrant may also be used (described later). The BML content has a list of mobile phone numbers registered in such a manner, and a BML script (for example, ECMAScript) that the received mobile terminal searches for a match with its own phone number from the list, Includes apps (for example, specific to mobile phone operators such as MIDP). In addition, the channel number and the broadcast time are posted at an evacuation center so that the portable terminal can receive this broadcast.

The mobile terminal receives the BML content, displays a telephone number registration screen according to the operation, and executes a script or the like. When it is realized only with a BML script, its own phone number is a character string (11 digits) that seems to be a phone number in the return value string while trying 1 to 3 for the argument of the extension function X_DPA_getIRDID (). If found, adopt it. Then, it searches its own telephone number from the list, and if there is a match, it prepares and saves the mail text and obtains the status of the communication function by X_DPA_getRevCond () as preparation for mail transmission. Then, if the mailer possible communication state, X_DPA_mailTo (), is transmitted specified destination (mail address registered person registered, or the server S) mail by packet communication network (semi) automatically . In the body of the mail, position information acquired by X_DPA_getCurPos (), an image taken by the owner of the mobile terminal on the spot, an arbitrary message, and the like can be stored.

  On the other hand, when using a mobile phone application, there is a difficulty that the application cannot be directly started from the C profile BML, or even the application cannot obtain its own phone number. Has the advantage of being accessible. Therefore, the phone number and name of the registrant are placed on the list, and the application searches the outgoing call history and address book for items that match them, and if there is, it performs a predetermined operation such as automatic mail transmission. To. As a result, the registrant can know the location of people who have a connection to the registrant.

  Regarding application activation, the BML script finds the received application for each business operator that matches the business operator of its own mobile terminal, saves it as a mobile phone application, and then sets the URI for each business operator. Open the HTML in the telco-specific browser by launchExApp () and launch the application from the HTML. Alternatively, in the BML content, a display prompting to start manually is performed. In addition to the above, this app can have various functions that are useful in the event of a disaster.

  The server S also provides the registered information of the inquiry person to the program editing apparatus 2, and the program editing apparatus 2 creates a program that sequentially displays the provided inquiry person information. This program is viewed on a large display terminal or a portable terminal installed in an evacuation center. When there is a response mail from the inquirer, the fact is also displayed on the program, and the registration itself is deleted after a predetermined time.

(Fourth embodiment)
The information transmission system according to the present embodiment is a traffic delay display system in which the system according to the second embodiment is used for actual transportation, not for amusement park vehicles. For example, in the railway, if the demand prediction and the operation (delay) situation are known, it can be predicted how much influence (stopping time) will occur on passengers, and it will be used as a judgment material on which transfer route to guide. In the traffic delay display system of this embodiment, the electronic message server is a unique server that is not on the Internet, and is used for business communication of station staff. In addition, content for station staff or the like cannot be viewed by general customers by limited reception. General passengers are provided with information such as delay information and transfer boarding information. Desirably, information on each railway company is provided in one program in the Kanto, Chubu, and other regions.

(Fifth embodiment)
The information transmission system of the present embodiment is obtained by adding a lost child search function as in Patent Document 3 to the system of the first embodiment. In other words, the image processing device 206 includes face detection, and when a person appears in the video, extracts the best shot face or whole body image, obtains a SIFT feature value (which is a multi-dimensional vector), and transmits it to the server S. The server S accumulates the received feature amount (and the extracted image) in the image DB for a certain period. When a lost person concerned (parent) communicates the characteristics of the lost child or provides an image to the server S of the center, the server S similarly obtains the feature amount from the provided image or the feature (expressed in language) that has been contacted. ) Are converted into feature amounts, and those having the same feature amounts are searched from the image DB and the live video of the camera. It is desirable that the image processing apparatus does not output the image and only the feature amount is stored in the image DB because the customer feels anxious about privacy when recording and collecting as an image.

(Sixth embodiment)
The information transmission system of this embodiment is obtained by adding a suspicious person searcher (prevention of removal) to the system of the previous fifth embodiment. In the image DB, an image of a suspicious person or its feature amount is registered, and if it is recognized as a suspicious person by feature amount comparison, it is tracked so that the behavior can be understood.

  In addition, IP cameras 205 were installed in each of the entrance / exit gates 202, etc., and an entrance ticket was inserted to acquire an image of each visitor and tried to leave with a different person (especially a suspicious person) at the time of entrance. In such a case, it is determined that the person has been taken away and an alarm is notified. Judgment should be given a wide range of conditions, such as limiting the number of people before and after the admission and the combination of adults and children.
