The present invention relates to a video information delivery and display system and a video information delivery and display method for delivering and providing video information using display devices set in cars of a train.
Recently, systems are proposed and put to practical use that deliver and provide video information to passengers using display devices set in cars of a train (see, for example, Patent Literatures 1 and 2).
In these video information delivery and display systems in the past, contents forming guidance screens for destination guidance and the like (hereinafter referred to as “guidance contents”) are stored in advance in storing units of the display devices as one content for each of the screens.
In this way, in the video information delivery and display system in the past, one guidance content is displayed for each of the screens stored in the storing unit. Therefore, even when information is the same except a part of train information such as a train type, a destination, or a car number, it is necessary to create one guidance content anew and store the guidance content in the storing unit. Therefore, there is a problem in that a data storage volume increases according to the number of guidance contents.
In the video information delivery and display system in the past, when the video information delivery and display system copes with, for example, addition of a station, even if there are common parts such as a train type, a destination, and a car number, it is necessary to create an entire guidance content anew. Therefore, there is a problem in that an increase in guidance contents is caused. Further, when it is desired to add, for example, date information, date information data has to be added to all guidance contents. Therefore, there is a problem in that considerable time and labor are required for correction of the guidance contents.
To solve these problems, in Patent Literature 3, in a system including display devices that display a guidance screen of a still image corresponding to train information, storing units are provided that store part contents, which are contents at a part level, respectively corresponding to pieces of information forming the guidance screen, a necessary part content is selected from the storing units according to train information, and the selected part content is arranged in a predetermined position on the guidance screen, whereby the guidance screen is formed. Consequently, it is possible to reduce a data storage volume and easily cope with addition and correction of guidance contents.

Patent Literature 2: Japanese Patent Application Laid-open No. 2003-95105
Patent Literature 3: Japanese Patent No. 3875950
However, in the system described in Patent Literature 3, because the guidance screen is the still image, there is a problem in that an amount of information provided to passengers and attention of the passengers to the information are generally small compared with those in the case of, for example, a moving image. On the other hand, it is also conceivable to display, for example, a guidance screen of a moving image on the display devices in the train. However, in the system in the past, there is a problem in that an enormous data storage capacity is necessary for the display of the moving image.
The present invention has been devised in view of the above and it is an object of the present invention to provide a video information delivery and display system and a video information delivery and display method that can increase an amount of information provided to passengers and attention of the passengers to the information while substantially reducing a data storage capacity necessary for display of guidance contents and can easily cope with addition and correction of display contents.
In order to solve above-mentioned problems and achieve the object of the present invention, according to an aspect of the present invention, there is provided a video information delivery and display system including: train information devices respectively mounted on cars, which form a train, and configured to manage train information in association with one another; display devices respectively mounted on the cars and including display units configured to display a guidance screen; a part-content storing unit configured to store a part content, which is a content at a part level, used for formation of the guidance screen; a part-arrangement-definition-data storing unit configured to store part arrangement definition data for defining arrangement of the part content on the guidance screen; a part-action-definition-data storing unit configured to store part action definition data for defining an action of the part content on the guidance screen; and a guidance-screen creating unit configured to select, according to a guidance content displayed on the guidance screen, based on the train information obtained from the train information devices, the part content used for the formation of the guidance screen from the part-content storing unit, arrange the selected part content on the guidance screen according to the part arrangement definition data, and cause the arranged part content to act according to the part action definition data to thereby cause the display units to display the guidance content.
According to another aspect of the present invention, there is provided a video information delivery and display method for, in a train including: train information devices respectively mounted on cars, which form a train, and configured to manage train information in association with one another; display devices respectively mounted on the cars and including display units configured to display a guidance screen; and a part-content storing unit configured to store a part content, which is a content at a part level, used for formation of the guidance screen, delivering video information and causing the display devices to display the video information, the video information delivery and display method including: acquiring the train information from the train information devices; selecting, according to a guidance content displayed on the guidance screen, based on the train information, the part content used for the formation of the guidance screen from the part-content storing unit; and arranging the selected part content on the guidance screen according to the part arrangement definition data and causing the arranged part content to act according to the part action definition data to thereby cause the display units to display the guidance content.
According to the present invention, the part content is caused to act to form the guidance screen. Therefore, it is possible to substantially reduce a data storage capacity necessary for display. According to the present invention, it is possible to increase an amount of information provided to passengers and attention of the passengers to the information compared with provision of information performed by using a still image.
According to the present invention, the guidance screen is formed by the part content and the arrangement and the actions of the part content are defined by the part arrangement definition data and the part action definition data. Therefore, it is possible to easily cope with addition and correction of display contents.
Embodiments of a video information delivery and display system and a video information delivery and display method according to the present invention are explained in detail below based on the drawings. The present invention is not limited by the embodiments.
The train information device 10 is a train information central device amounted on, for example, the front car (the first car). The train information devices 11 are train information terminal devices respectively mounted on the cars. The train information devices 10 and 11 are connected to each other via a transmission line 12. The train information devices 10 and 11 perform management, collection, and the like of train information in cooperation with each other and share the train information. The train information device 10 is connected to various control devices and controls the train information devices 11. Examples of train information managed by the train information devices 10 and 11 include starting station information, train type information, number car information, destination information, train name information, traveling location information, speed information, and door opening and closing information. These kinds of train information can be notified from the video information delivery device 20 to the diverting devices 21 via a transmission line 22.
The video information delivery device 20 is mounted on, for example, the front car and performs delivery of stored video information as needed. The video information delivery device 20 is connected to the train information device 10 and the radio transceiver 50 in the same car. Further, the video information delivery device 20 is connected to the diverting devices 21, which are respectively mounted on the cars, via the transmission line 22. The diverting devices 21 are respectively connected to, for example, a plurality of display devices 30. In other words, for example, the display devices 30 are respectively mounted on the cars.
Service information and the like of a route are transmitted from the ground station 51 to the onboard system 70. The transmitted service information and the like of the route are received by the radio transceiver 50. The received service information and the like of the route are transmitted to the train information device 10 through the video information delivery device 20 and further transmitted to the train information devices 11, which are mounted on the cars, via the transmission line 12. Service information (e.g., a destination, a train type, and a starting station) of the train is input to and set in the train information device 10 during the start of a service. These kinds of service information input and set during the start of the service are transmitted to the train information devices 11 in the cars via the transmission line 12. Train information including the service information and the like of the route collected by the train information devices 11 in the cars is transmitted to and received from each other via the transmission line 12. These kinds of train information are shared by the train information devices 11 and the train information device 10. The train information devices 11 in the cars respectively transmit the train information to the display devices 30 via the diverting devices 21. These kinds of service information can be notified from the video information delivery device 20 to the diverting devices 21 via the transmission line 22.
The video information delivery device 20 acquires video information from the ground station 51 via the radio transceiver 50. This video information is, for example, part content data explained later. The video information delivery device 20 transmits the received video information to the display devices 30, which are mounted on the cars, through, for example, a route same as the route for the delivery of the train information, i.e., through the train information device 10, the train information devices 11, and the diverting devices 21. Instead of being acquired from the ground station 51, the video information can be directly input to the video information delivery device 20 using a storage medium, a notebook PC, or the like (not shown). Besides the above route, a transmission route of the video information from the video information delivery device 20 to the display devices 30 can be a route directly reaching the display devices 30 through the diverting devices 21, and not through the train information devices 10 and 11. In this case, the diverting devices 21 divert a signal, which flows through the transmission line 22, to the display devices 30 provided in the cars. In this way, these kinds of train information can be notified from the video information delivery device 20 to the diverting devices 21 via the transmission line 22.
An overview of guidance screen creation processing by the screen creating unit 32 is explained. Details of an operation are explained later. First, in this embodiment, as in the case of the still image described in Patent Literature 3, a guidance screen is formed by assembling parts. For example, as shown in
Subsequently, the screen creating unit 32 arranges, referring to the part arrangement definition data stored in the part-arrangement-definition-data storing unit 31B, the part contents (the train type 101, the destination 102, the car number 103, the guidance type 104, the station name 105, etc.) respectively in predetermined positions on the guidance screen 1. In other words, the screen creating unit 32 forms a guidance screen 1 by pasting the selected part contents to the guidance screen 1 and assembling the part contents. The guidance screen 1 formed in this way is an initial screen (a first frame) that forms guidance contents.
Each of the part contents has a small data volume compared with one guidance screen. The part contents can be diverted to various guidance contents. Therefore, it is possible to reduce a data storage capacity of the entire system by using such part contents.
In this embodiment, not only sections (e.g., the train type 101 shown in
The screen creating unit 32 refers to the part action definition data stored in the part-action-definition-data storing unit 31C. The part action definition data defines the actions of part contents on the guidance screen 1. Examples of the actions of the part contents include a moving action, a rotating action, an expanding or reducing action, and an appearing or disappearing action. The appearing or disappearing action represents a change in which the transmittance of the part contents temporally changes and the part contents gradually appear from a transparent state or gradually shift to the transparent state. A change in a color (changes in a hue, a tint, brightness, etc.) can be included in this action. Besides, various actions can be defined.
The screen creating unit 32 sequentially creates the guidance screen 1 in which the part contents are caused to act according to the part action definition data and performs display of guidance contents by causing the display unit 33 to display the guidance screen 1. As explained later in detail, the screen creating unit 32 creates a screen in which the part contents are caused to slightly act from the initial screen and creates a screen in which the part contents are further caused to slightly act from the created screen. In this way, the screen creating unit 32 sequentially creates a plurality of screens in which the part contents are caused to act according to the part action definition data and performs display of guidance contents by displaying these screens in time series.
The operation in this embodiment is explained in detail with reference to
As shown in
As shown in
Subsequently, the screen-creation-instruction-file generating unit 32A determines a train state based on the acquired train information (S2). Specifically, the train information is classified into, for example, train information during a stop at a station, train information during traveling, and train information during approach to the next station. The screen-creation-instruction-file generating unit 32A determines, from the acquired train information, in which of the three states the train is. These three states are an example. Other classifications can be adopted.
When it is determined as a result of the determination of the train state at S2 that the train is, for example, stopping at a station, the screen-creation-instruction-file generating unit 32A determines, referring to the guidance display order data during a stop at a station stored in the guidance-display-order-data storing unit 31D, guidance contents (referred to as roles) that should be sequentially displayed at the station at which the train stops (S3). In an example shown in
When it is determined as a result of the determination of the train state at S2 that the train is traveling, the screen-creation-instruction-file generating unit 32A determines, referring to the guidance display order data during traveling stored in the guidance-display-order-data storing unit 31D, guidance contents (roles) that should be sequentially displayed during traveling (S4). In the example shown in
When it is determined as a result of the determination of the train state at S2 that the train is approaching the next station, the screen-creation-instruction-file generating unit 32A determines, referring to the guidance display order data during approach to the next station stored in the guidance-display-order-data storing unit 31D, guidance contents (roles) that should be sequentially displayed during approach to the next station (S5). In the example shown in
The screen-creation-instruction-file generating unit 32A determines, according to the guidance contents (roles) that should be displayed, based on the train information, part contents used for formation of the guidance screen 1 (S6). For example, as shown in
The screen-creation-instruction-file generating unit 32A acquires initial arrangement information on the guidance screen 1 of the part contents by referring to the part arrangement definition data stored in the part-arrangement-definition-data storing unit 31B and acquirers initial information concerning actions of the part contents by referring to the part action definition data stored in the part-action-definition-data storing unit 31C. The screen-creation-instruction-file generating unit 32A generates, from these kinds of acquired information, an initial file 6A in which creation instruction contents for creating a first frame forming a guidance content are described (S7). The initial file 6A is one of the screen creation instruction files 6 described above. A screen creation instruction file can be created by, for example, embedding the acquired information in a template file (not shown) prepared in advance for each of guidance contents. The template file serving as a basis of such a screen creation instruction file is stored in the storing unit 31 in advance.
As the part arrangement definition data, arrangement positions of the part contents used for the formation are defined, for example, for each type of a guidance content or guidance, by, for example, coordinate values of an XY coordinate set on the guidance screen 1. The part action definition data defines an action of each of parts (i.e., each of part contents) forming the guidance screen 1. As a specific example of the part action definition data, for example, concerning a part P1, it is described that the part P1 is rotated 90° counterclockwise at constant angular velocity on the guidance screen 1 from 0 second at the start to T seconds at the end. For example, concerning a part P2, it is described that the part P2 stands still from 0 second at the start to T1 seconds, moves at equal velocity in a fixed direction from T1 seconds to T2 seconds, and stands still again from T2 seconds to T seconds at the end. For example, concerning a part P3, it is described that the part P3 does not act. For example, concerning a part P4, it is described that transmittance is 100% from 0 second at the start to T3 seconds, the transmittance decreases to 50% from T3 seconds to T4 seconds, and the part P4 is displayed at fixed transmittance again from T4 seconds to T seconds at the end. For example, concerning a part P5, it is described that the part P5 is displayed at a size of 100% from 0 second at the start to T5 seconds, the size is increased to 150% from T5 seconds to T6 seconds, and a fixed size is maintained again from T5 seconds to T seconds at the end.
The initial file 6A includes an instruction for initial arrangement positions of part contents obtained from the part arrangement definition data and includes, for example, when the transmittance of the part contents temporally changes, an instruction for initial transmittance (i.e., initial information of the action) obtained from the part action definition data. Besides, the initial file 6A includes information necessary for creation of the first frame such as information concerning association of the part contents used for the formation and image files actually stored in the part-content storing unit 31A. The initial file 6A is desirably, for example, a text file for the purpose of a reduction in a data storage capacity. In this case, instruction contents necessary for creation of the guidance screen 1 are described in a text format.
The screen-creation-instruction-file generating unit 32A generates, based on the part action definition data, a plurality of difference files 6B in which creation instruction contents of remaining all frames following the first frame are individually described (S7). These difference files 6B are files for instructing creation of difference display contents for the continuous frames and are the screen creation instruction files 6.
To specifically explain the difference files 6B, it is assumed that the guidance contents are formed in, for example, T seconds and, for example, M frames are generated and displayed in T seconds (M is an integer equal to or larger than 2). M is set to a number equal to or larger than a number for allowing the guidance contents to be smoothly displayed. Action examples of parts described in the part action definition data are explained with the action of the part P1 as an example. It is assumed that the part P1 rotates 90° counterclockwise on the guidance screen 1 in T seconds. Then, the part P1 rotates (90/M)° counterclockwise among the continuous frames. The screen-creation-instruction-file generating unit 32A calculates, as in this example, based on the description of the part action definition data, actions among the frames as difference information and describes the difference information in the difference files 6B. Specifically, after generating the initial file 6A, the screen-creation-instruction-file generating unit 32A generates a first difference file 6B in which difference information indicating that, for example, the part P1 rotates (90/M)° counterclockwise is described as a creation instruction content for a second frame following the first frame. In this configuration, the second frame can be created by the initial file 6A and the first difference file 6B. Similarly, the screen-creation-instruction-file generating unit 32A generates a second difference file 6B in which a creation instruction content for a third frame following the second frame is described as a difference display content between the frames. The third frame can be created by the initial file 6A and the first and second difference files 6B. The same holds true in other cases. The initial file 6A and the difference files 6B are stored in the storing unit 31.
As explained above, in this embodiment, the screen-creation-instruction-file generating unit 32A generates the initial file 6A and the difference files 6B as the screen creation instruction files 6 for creating a plurality of frames forming a guidance content. However, instead of generating the difference files 6B, it is also possible to create files similar to the initial file 6A for all the frames. For example, instead of generating the first difference frame 6B to correspond to the second frame, it is also possible to generate, from the beginning, a file obtained by combining the contents of the initial file 6A and the first difference file 6B. As in this embodiment, because the difference files 6B are generated, it is unnecessary to describe redundant contents among the frames. Therefore, there is an effect that a data storage capacity can be reduced.
Display processing for guidance contents by the image-file generating unit 32B is explained. As shown in
On the other hand, when the display is a display of a frame after the first frame (a frame other than the first frame) as a result of the determination at S8 (No at S8), the image-file generating unit 32B generates, based on data contents obtained by reflecting contents of the difference files 6B for creating a display target frame on screen creation instruction data used in the last display, the image file 8 corresponding to the data contents (S9). The screen creation instruction data used in the previous display is data of the initial file 6A or the initial file 6A and the difference files 6B used for creation of a file displayed immediately before the display. For example, when a second frame is displayed, the screen creation instruction data used in the last display is data of the initial file 6A. For example, when a third frame is displayed, the screen creation instruction data used in the last display is data of the initial file 6A and the first difference file 6B. In other words, contents of the difference files 6B of the display target frame are added to data used for creation of an immediately preceding frame and already expanded on a memory to simplify the processing and realize a reduction in a data storage capacity.
Subsequently, the image-file generating unit 32B outputs an image based on the generated image file 8 to the display unit 33 as a display target frame (S11). Thereafter, the same operation is repeated until display of all frames ends. In this way, the image-file generating unit 32B generates the image files 8 respectively based on the screen creation instruction files 6 for the number of generated frames and expands and displays these image files 8 in time series on the display unit 33 to display guidance contents (roles).
The image-file generating unit 32B generates an image adjusted to a size of an actual guidance screen from the image files 8 and stores this image in a frame buffer (not shown) provided in the display unit 33. The display unit 33 reads out the image in the frame buffer and displays the image on a screen.
It is desirable to set the capacity of the frame buffer to a capacity enough for storing a plurality of guidance contents. In this case, the image-file generating unit 32B can store, for example, an image group concerning a guidance content scheduled to be displayed next in the frame buffer in addition to an image group concerning a guidance content currently displayed. Consequently, after the end of display of the guidance content currently displayed, image groups concerning a guidance content scheduled to be displayed next can be immediately read out and displayed sequentially. Therefore, a display switching becomes smooth.
The image-file generating unit 32B can generate an image from the image files 8 and, after storing this image in the frame buffer, erase the image files 8, whose image generation ends. Consequently, it is unnecessary to store the image files 8 having a large data size after the image generation. It is possible to substantially reduce a data storage capacity.
In guidance during traveling shown in
In
When a data format of data stored in the part-content storing unit 31A is, for example, so-called vector data, the image-file generating unit 32B can easily generate, based on the initial file 6A and the difference files 6B, an image file obtained by causing part contents to act. However, this embodiment is not limited to a display method employing this data format.
Specifically, characters are changed from “Kasumigaseki in Chinese characters” to “Kasumigaseki in hiragana characters”.
In
The part contents 120 and 121 are respectively still images on which “Kasumigaseki in hiragana characters” and “Kasumigaseki in Chinese characters” are inscribed.
As shown in
Subsequently, for “frame (2N+1)”, which is a (2N+1)th frame displayed after the elapse of 2 seconds, it is described in the difference files 6B used for creation of the frame that “the transmittance of the part P changes by −α and the transmittance of the part Q changes by +α”. After the image file 8 is created based on the difference files 6B and the initial file 6A, an image corresponding to the image file 8 is output to the display unit 33. Thereafter, an operation performed up to “frame (3N+1)” is as explained with reference to
As it is seen from comparison of the display content of the part P shown in
As a result, “Kasumigaseki in hiragana characters” is displayed.
The action is obtained by combining the actions of the part content 110 shown in
As explained above, according to this embodiment, the guidance screen 1 for the guidance contents is formed using the part contents. Therefore, it is possible to substantially reduce a data storage capacity necessary for display, i.e., the capacity of the storing unit 31.
According to this embodiment, it is possible to increase an amount of information provided to passengers and attentions of the passengers to the information, a visual appealing effect to the passengers increases, and it is possible to more effectively provide information compared with provision of information performed by using a still image.
According to this embodiment, the guidance screen 1 is formed by the part contents. The arrangements and the actions of the part contents are defined by the part arrangement definition data and the part action definition data. Therefore, it is possible to easily cope with additions and corrections of display contents.
In this embodiment, the difference files 6B are generated as the screen creation instruction files for creating the second and subsequent frames. Therefore, it is unnecessary to describe redundant display contents among the frames. It is possible to reduce a data storage capacity.
The image-file generating unit 32B can generate an image from the image files 8 and, after storing this image in the frame buffer, erase the image files 8, whose image generation ends. Consequently, it is unnecessary to store the image files 8 having a large data size after the image generation. It is possible to substantially reduce a data storage capacity.
The image file generation processing by the image-file generating unit 32B concerning a guidance content currently displayed and the generation processing for a screen creation instruction file by the screen-creation-instruction-file generating unit 32A concerning a guidance content scheduled to be displayed next can be performed in parallel. Consequently, a creation of a screen creation instruction file for the next guidance content is not started after the end of display of the guidance content currently displayed. A period in which no guidance content is displayed does not occur between the guidance contents.
In
For example, in the guidance during traveling shown in
A change in a color can also be added to the actions of part contents. For example, as the train approaches the next station, it is also possible to perform display for increasing attentions of passengers by, for example, gradually changing character displays from black to blue and from blue to red.
In this embodiment, functions necessary for guidance content creation such as the screen creating unit 32, the part-content storing unit 31A, the part-arrangement-definition-data storing unit 31B, and the part-action-definition-data storing unit 31C are provided in the display device 30. When a plurality of the display devices 30 are provided in a car, such a configuration is suitable for displaying different guidance contents for each of the display devices 30.
On the other hand, the functions necessary for guidance content creation can also be provided in, for example, the diverting devices 21 shown in
As still another configuration, the functions necessary for guidance content creation can also be provided in, for example, the video information delivery device 20. Such a configuration is still more inexpensive because the number of the set screen creating units 32 is further reduced. The configuration is suitable for displaying the same guidance contents in all the display devices 30 in the train. In this case, the video information delivery device 20 delivers created guidance contents to the display devices 30 rather than delivering part contents.
According to this embodiment, a still image can also be displayed. Specifically, all part contents only have to be defined as “no action” in the part action definition data. For example, in
In the guidance contents in this embodiment, it is also possible to embed a photographed video in a part of the guidance screen 1, display this photographed video at a same timing as the timing for frame display, and cause a photographed video display section to act, for example, move in the guidance screen 1. However, because the photographed video requires a large data size, it is desirable to use the photographed video while limiting the data size. When such a photographed video is used, as in Patent Literature 3, a route for transmitting data from the video information delivery device 20 to the display devices 30 can be divided for transmission of part contents and transmission of the photographed video. In other words, in Patent Literature 3, the photographed video is transmitted to the display devices 30 directly through the diverting devices 21 without being transmitted through the train information devices 11.
In the first embodiment, the system and the method for selecting, based on train information obtained from the train information devices 11, part contents necessary for formation of guidance contents from the part content group stored in the part-content storing unit 31A in advance, assembling these part contents, and giving actions to the part contents to perform display of the guidance contents are explained.
In the second embodiment, a system and a method for incorporating, in guidance contents, information not directly obtained from the train information devices 11, for example, temporary information provided from the outside of a train and displaying the temporary information are explained. The temporary information is, for example, service information, accident information, or a news flash. Such temporary information is provided from, for example, the ground station 51 by radio communication.
To perform the display shown in
In the display example shown in
In the above explanation, the temporary information is obtained from, for example, the ground station 51. However, the temporary information can be input to the video information delivery device 20 via a predetermined input means by, for example, a crew member on a car. For example, the crew member can input temporary information concerning a failure, an accident, or a sick person in a train on which the crew member works to the video information delivery device 20 via an input screen or the like of an onboard monitor device. The temporary information input onboard is displayed by telop on the guidance content in the same manner as described above. Therefore, it is possible to provide information having higher real-time properties than the information from the ground station 51.
According to this embodiment, for example, temporary information provided from the outside of a train or input onboard is processed into a part content as a character drawing and the part content is incorporated in a moving image of a guidance content and displayed. Therefore, it is possible to provide passengers with the temporary information on a real-time basis. The other components, actions, and effects of this embodiment are the same as those in the first embodiment.
In this embodiment, as a specific example of the actions of part contents, actions of parts displayed as if the parts are rotating on a guidance screen according to a combination of reducing and expanding actions are explained. A configuration and the like of this embodiment are the same as those in the first and second embodiment. Actions are defined in part action definition data.
As shown in
Specifically, display switching is performed from “Kasumigaseki in hiragana characters” of the part R to “Kasumigaseki” of the part S.
The top section in the figure indicates an action start state and the bottom section indicates an action end state. The part R is displayed based on a part content 126 shown in
First, the action of the part R is explained. In the figure, the vertical direction is referred to as a first direction and a direction orthogonal to the first direction is referred to as a second direction. The part R is reduced at, for example, a fixed reducing speed (referred to as a first reducing speed) in the first direction in a state in which an end E1, which is one end of the part R in the first direction, is fixed not to move in the first direction. Specifically, the action of the part R is specified such that the part R reduces in the first direction from the start of the action to the end of the action and has no width in the first direction in an action end state. Therefore, an end E2, which is the other end of the part R, opposed to the end E1 moves downward at the first reducing speed, whereby an area where the part S is displayed is formed on the upper side of the end E2 and this formed area gradually increases.
The part R reduces in the first direction and also reduces in the second direction. However, reducing speed of the part R in the second direction increases at a fixed rate from 0 to predetermined reducing speed (referred to as second reducing speed) from the end E2 toward the end E1. Therefore, the length of the end E2 is fixed but the length of the end E1 decreases as time elapses. Therefore, there is an effect that the part R is displayed with temporally-changing perspective given thereto. The part R looks as if the part R is rotating downward with the second direction as a rotation axis. In the upper section of
The action of the part S is explained. For convenience of explanation, the action of the part S is specified as an opposite action of an action from the end of the action to the start of the action in time reversal. Specifically, when the part S shifts from the action end state in the bottom section of
According to this embodiment, by combining a combination of reducing actions of the part R and a combination of expanding actions of the part S as explained above, it is possible to display the parts R and S as if the parts R and S are rotating.

In the explanation of this embodiment, the rotating direction is downward in the figures. However, the same explanation applies when the rotating direction is an arbitrary direction of the guidance screen.
As explained above, the present invention is useful as a video information delivery and display system and a video information delivery and display method that can increase an amount of information provided to passengers and substantially reduce a data storage capacity.
