However, even if the other information is the same, it is necessary to newly create one guidance content and store it in the storage unit. Therefore, there is a problem that the data storage capacity increases according to the number of guidance contents.

  In addition, in the conventional video information distribution and display system, it is necessary to newly create the entire guidance content even if there are common parts such as train type, destination, and car number when responding to the expansion of stations, etc. There has been a problem in that the content of guidance is increased. Furthermore, for example, when it is desired to add date information or the like, the date information data must be added to all the guidance contents, and there is a problem that a great deal of time and labor is required to correct the guidance contents.

  With respect to these problems, in Patent Document 3, in a system including a display device that displays a still image guide screen corresponding to train information, content at a component level corresponding to each piece of information constituting the guide screen is used. A storage unit for storing a part content is provided, a necessary part content is selected from the storage unit according to the train information, and the selected part content is arranged at a predetermined position on the guide screen to configure a guide screen. Yes. As a result, the data storage capacity can be reduced, and the guidance content can be easily added or modified.

  Embodiments of a video information delivery / display system and a video information delivery / display method according to the present invention will be described below in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.

Embodiment 1 FIG.
FIG. 1 is a diagram showing an overall configuration of a video information delivery / display system according to the present embodiment. The video information distribution and display system according to the present embodiment includes an on-vehicle system 70 constructed on a train composed of a plurality of vehicles (No. 1 to No. n; n is an integer of 2 or more), and a ground system. And a ground station 51. The on-board system 70 includes train information devices 10 and 11, a video information distribution device 20, a branching device 21, a display device 30, a wireless transmission / reception device 50, and the like. The on-board system 70 can transmit / receive data to / from the ground station 51 by the wireless transmission / reception device 50.

  The train information device 10 is, for example, a train information central device mounted on the leading vehicle (car 1), and the train information device 11 is a train information terminal device mounted on each vehicle. The train information devices 10 and 11 are connected to each other via a transmission line 12, and manage and collect train information in cooperation with each other and share train information. The train information device 10 is connected to various control devices and controls the train information device 11. Examples of train information managed by the train information devices 10 and 11 include departure station information, train type information, car information, destination information, train name information, travel position information, speed information, door opening / closing information, and the like. Note that the train information may be notified from the video information distribution device 20 to the branch device 21 via the transmission path 22.

  The video information distribution device 20 is mounted on, for example, the leading vehicle, and distributes the video information held as necessary. The video information distribution device 20 is connected to the train information device 10 and the wireless transmission / reception device 50 of the vehicle. Further, the video information distribution device 20 is connected to a branch device 21 mounted on each vehicle via a transmission path 22, and each of the branch devices 21 is connected to, for example, a plurality of display devices 30. That is, for example, a plurality of display devices 30 are mounted on each vehicle.

  Route information and the like are transmitted from the ground station 51 to the on-board system 70, and the transmitted route information and the like are received by the wireless transmission / reception device 50. The received route operation information and the like are transmitted to the train information device 10 via the video information distribution device 20 and further transmitted to the train information device 11 mounted on each vehicle via the transmission path 12. The train information device 10 is input and set with the train operation information (for example, destination, train type, departure station, etc.) at the start of operation. The operation information input and set at the start of the operation is transmitted to the train information device 11 of each vehicle via the transmission path 12. Moreover, the train information collected by the train information device 11 of each vehicle is transmitted / received to / from each other via the transmission path 12, and the train information is shared by the train information device 11 and the train information device 10. The train information device 11 of each vehicle transmits train information to the display device 30 via the branch device 21. Note that the operation information information may be notified from the video information distribution device 20 to the branching device 21 via the transmission path 22.

  In addition, the video information distribution device 20 acquires video information from the ground station 51 by the wireless transmission / reception device 50. This video information is, for example, component content data described later. The video information distribution device 20 displays the received video information on a display device mounted on each vehicle via, for example, the same route as the distribution of train information, that is, the train information device 10, the train information device 11, and the branch device 21. 30. Instead of acquiring the video information from the ground station 51, it is also possible to directly input the video information to the video information distribution apparatus 20 using a storage medium, a notebook PC or the like (not shown). In addition to the above, the transmission path of the video information from the video information distribution device 20 to the display device 30 is a route that directly reaches the display device 30 via the branch device 21 without passing through the train information devices 10 and 11. It can also be. At this time, the branching device 21 branches the signal flowing through the transmission path 22 to the display device 30 provided in each vehicle. In this way, the train information may be notified from the video information distribution device 20 to the branch device 21 via the transmission path 22.

  FIG. 2 is a block diagram illustrating a configuration of the display device 30. The display device 30 includes a storage unit 31 such as a memory that stores various definition data and component content data, which will be described later, a screen creation unit 32 that is connected to the storage unit 31 and creates a guide screen for video information, and the screen And a display unit 33 that displays the guidance screen created by the creation unit 32. The screen creation unit 32 is realized by, for example, hardware such as a CPU and predetermined software that operates in cooperation with the hardware.

  FIG. 3 is a diagram illustrating an example of the contents stored in the storage unit 31. As shown in FIG. 3, the storage unit 31 defines a component content storage unit 31 </ b> A that stores component content that is component-level content used for the configuration of the guide screen, and the arrangement position of the component content on the guide screen. A component arrangement definition data storage unit 31B that stores the component arrangement definition data and a component operation definition data storage unit 31C that stores the component operation definition data that defines the operation of the component content on the guidance screen are provided. As will be described later, the component content is an image as a component. The component arrangement definition data is described in, for example, a text format in the component arrangement definition data file. The component operation definition data is described in, for example, a text format in the component operation definition data file. In FIG. 3, the storage unit 31 collectively shows storage areas in the display device 30. Therefore, it does not necessarily indicate that the component content storage unit 31A, the component arrangement definition data storage unit 31B, and the component operation definition data storage unit 31C are all stored in the same storage medium. May be stored in the storage medium.

  Here, an outline of the guide screen creation process by the screen creation unit 32 will be described. Details of the operation will be described later. First, in the present embodiment, as in the case of the still image described in Patent Document 3, the guide screen is configured by assembling parts. For example, as shown in FIG. 4, when each information of train type 101, destination 102, car number 103, guidance type 104, and station name 105 is displayed on the guidance screen 1, these information are respectively set as parts (parts). Constitute. Then, after acquiring train information from the train information device 11, the screen creation unit 32 selects a component content corresponding to the train information obtained for each part from the component content storage unit 31A. For example, when it is determined that the train type is “Each Station Stop” based on the train information, the screen creation unit 32 selects “Each Stop_Yuki” as the component content to be used for displaying the train type 101. The same applies to other parts, and the screen creation unit 32 selects part contents corresponding to the train information. The component content group stored in the component content storage unit 31A is still image data and is distributed from the video information distribution device 20.

  Subsequently, the screen creation unit 32 refers to the component arrangement definition data stored in the component arrangement definition data storage unit 31B, and each component content (train type) is displayed at a predetermined position on the guide screen 1 as shown in FIG. 101, destination 102, car number 103, guidance type 104, station name 105, etc.). That is, the screen creation unit 32 configures the guidance screen 1 by pasting each selected component content on the guidance screen 1 and assembling the component content. The guide screen 1 configured in this way is an initial screen (first frame) that forms guide content.

  Since each component content has a smaller data capacity than a single guidance screen, and the component content can be used for various guidance contents, the entire system can be obtained by using such component content. As a result, the data storage capacity can be reduced.

  Moreover, in this Embodiment, not only a part (for example, train classification 101 etc. of FIG. 4) in which display content changes depending on train information is used as a part, but a part in which display content does not depend on train information (for example, A base part etc.) can also be a part. When at least one part is defined, the remaining part of the guidance screen 1 can be regarded as a part. For example, when considering a configuration in which the train type 101, destination 102, car number 103, guidance type 104, station name 105, etc. in FIG. 4 are pasted on a base part having a uniform background color, the base part can also be regarded as a part. it can. By converting parts of the display content that do not depend on train information into parts, such parts may be shared between different guidance contents, which contributes to a reduction in content storage capacity of the entire system. For example, the map part used for the plane route map is effective because it can be shared.

  Next, the screen creation unit 32 refers to the component operation definition data stored in the component operation definition data storage unit 31C. The component operation definition data defines the operation of each component content on the guidance screen 1. Examples of the operation of the component content include a movement operation, a rotation operation, an enlargement or reduction operation, and an appearance or disappearance operation. Here, the appearance or disappearance operation represents a change in which the transparency of the component content changes with time and gradually appears from the transparent state or gradually shifts to the transparent state. Also, color changes (changes in hue, color, brightness, etc.) can be included in this operation. Various other operations can be defined.

  FIG. 5 is a diagram illustrating an operation example of the component content 110. FIG. 5A shows an operation in which the component content 110 is translated in one direction. Arrows indicate the direction of movement. FIG. 5B shows an operation in which the component content 110 </ b> A rotates clockwise in the guidance screen 1. Further, the component content 110B shows an operation in which the display content rotates in the direction of the arrow about a horizontal axis parallel to the guide screen 1. In this case, the arrangement position of the component content 110B does not change, but the display content rotates. FIG. 5C shows an operation for expanding the component content 110. FIG. 5D shows an operation in which the component content 110 is translated in the direction of the arrow and its transparency increases with time, so that the component content 110 is gradually made transparent.

  Next, the screen creation unit 32 sequentially creates the guidance screen 1 in which each component content is operated according to the component operation definition data, and displays the guidance screen 1 on the display unit 33 to display the guidance content. Although details will be described later, a screen in which each component content is slightly operated with respect to the initial screen is created, and a screen in which each component content is slightly operated is created with respect to the created screen. A plurality of screens in which the component contents are operated according to the component operation definition data are sequentially created, and the guidance contents are displayed by displaying these screens in time series.

  Next, the operation of the present embodiment will be described in detail with reference to FIGS. 6 is a diagram showing the functional configuration of the screen creation unit 32, FIG. 7 is a diagram showing a more detailed example of the contents stored in the storage unit 31, FIG. 8 is a flowchart showing the operation of the present embodiment, and FIG. FIG. 10 is a diagram illustrating an example of guidance display between stations.

  As shown in FIG. 6, the screen creation unit 32 creates a screen creation instruction file that is a file in which creation instruction contents of a plurality of frames (component images) that are continuous in time series constituting the guide content are described. An instruction file generation unit 32A and an image file generation unit 32B that generates each frame based on the screen creation instruction file are configured. As shown in FIG. 7, in addition to the configuration of FIG. 3, the storage unit 31 stores station stop guidance display order data, traveling guidance display order data, and station approaching guidance display order data, which will be described later. A guidance display order data storage unit 31D is provided.

  As shown in FIG. 8, first, the screen creation instruction file generation unit 32A acquires train information (S1). The train information may be acquired directly from the train information device 11 or may be acquired from the storage unit 31 after being temporarily stored in the storage unit 31.

  Next, the screen creation instruction file generation unit 32A determines the train state based on the acquired train information (S2). Specifically, the train state is classified as, for example, when the station is stopped, traveling, or approaching the next station, and the screen creation instruction file generation unit 32A determines whether the train is in any of the three states from the obtained train information. It is judged whether it is in the state of. Note that these three states are examples, and other classifications may be adopted.

  As a result of the determination of the train state in S2, for example, if it is determined that the train is stopped at the station, the screen creation instruction file generation unit 32A displays the guidance display order during the station stop stored in the guidance display order data storage unit 31D. With reference to the data, guidance contents (referred to as rolls) to be sequentially displayed at the stop station are determined (S3). In the example shown in FIG. 10, when the train is stopped at, for example, the “National Diet Building” station, the “station equipment guidance” that is the guidance content is displayed. This displays the “station equipment guidance” at the station. This is because what should be described in the guidance display order data during stoppage. The “station equipment guide” is repeatedly displayed in units of a predetermined time (this time is T seconds).

  When it is determined that the train is traveling as a result of the determination of the train state in S2, the screen creation instruction file generation unit 32A stores the traveling guidance display order data stored in the guidance display order data storage unit 31D. Referring to FIG. 4, guidance contents (rolls) to be sequentially displayed during traveling are determined (S4). In the example shown in FIG. 10, when the train is traveling between “National Diet Building-Kasumigaseki” stations, “Neighboring route guidance (Japanese)”, “Nearby route guidance ( (English) ”,“ Wide-area route guidance (Japanese) ”, and“ Transfer guidance ”are displayed in this order. In addition, the guidance contents of “Nearby Route Guidance (Japanese)”, “Nearby Route Guidance (English)”, “Wide Area Route Guidance (Japanese)”, and “Transfer Guidance” each have T seconds as described above. It is displayed as a unit, and these roles are repeatedly displayed.

  If it is determined as a result of the determination of the train state in S2 that the train is approaching the next station, the screen creation instruction file generation unit 32A guides the station approaching information stored in the guidance display order data storage unit 31D. With reference to the display order data, guidance contents (rolls) to be sequentially displayed while approaching the next station are determined (S5). In the example shown in FIG. 10, when the train is approaching “Kasumigaseki” station, for example, “next station facility guidance” and “door opening guidance” are displayed in this order according to the station approaching guidance display order data. Further, the guidance contents of “next station facility guidance” and “door opening guidance” are each displayed in units of T seconds as described above, and these rolls are repeatedly displayed. Note that whether or not the train is approaching the next station is determined based on, for example, whether or not the distance from the train to the next station is a predetermined distance or less.

  Next, the screen creation instruction file generation unit 32A determines the component content used for the configuration of the guidance screen 1 based on the train information according to the guidance content (roll) to be displayed (S6). For example, as shown in FIG. 4, when the train type 101 is one of the parts, when it is determined that the train is “stop at each station” based on the train information, “each stop_yuki” Is determined.

  Subsequently, the screen creation instruction file generation unit 32A refers to the component placement definition data stored in the component placement definition data storage unit 31B, acquires initial placement information on the guidance screen 1 of each component content, and performs component operations. In order to acquire the initial information of the operation of each component content with reference to the component operation definition data stored in the definition data storage unit 31C, and to create the first frame constituting the guidance content from the acquired information An initial file 6A describing the contents of the creation instruction is generated (S7). The initial file 6A is one of the screen creation instruction files 6 described above. The screen creation instruction file can be created, for example, by embedding the acquired information in a template file (not shown) prepared in advance for each guidance content. A template file serving as a basis for such a screen creation instruction file is stored in the storage unit 31 in advance.

  Here, the component arrangement definition data defines, for example, for each guidance content or guidance type, the arrangement position of each component content used in the configuration by, for example, coordinate values based on XY coordinates set on the guidance screen 1. The component operation definition data defines an operation for each part (that is, for each component content) constituting the guide screen 1. If the specific example is given, about the part P1, for example, it will be described that it rotates counterclockwise on the guidance screen 1 at a constant angular velocity of 90 ° from the start 0 seconds to the end T seconds. For example, the part P2 is in a stationary state from the start 0 seconds to T1 seconds, is moved at a constant speed from the T1 seconds to T2 seconds, and is in a stationary state again from the T2 seconds to the end T seconds. The effect is described. For example, regarding the part P3, it is described that there is no operation. For example, for part P4, the transparency is 100% from the start 0 second to T3 seconds, the transparency decreases to 50% from T3 seconds to T4 seconds, and again from T4 seconds to the end T seconds. It is described that the display is performed with a certain transparency. Also, for example, for part P5, the display is displayed in 100% size from the start 0 second to T5 second, the size is expanded to 150% from T5 second to T6 second, and from T5 second to the end T second. Is described to maintain a certain size again.

  The initial file 6A includes an initial location position of the component content obtained from the component placement definition data, and the initial transparency obtained from the component operation definition data (when the transparency of the component content changes with time). That is, in addition to an instruction of the above-described initial operation information), the first frame is created such as association information between the component content used in the configuration and the image file actually stored in the component content storage unit 31A. Contains necessary information. The initial file 6A is preferably a text file, for example, for the purpose of reducing the data storage capacity. In this case, the instruction content necessary for creating the guidance screen 1 is described in a text format.

  Next, the screen creation instruction file generation unit 32A generates a plurality of difference files 6B that individually describe the creation instruction contents of all the remaining frames following the first frame based on the component operation definition data (S7). . These difference files 6B are files for instructing creation of the difference display contents for consecutive frames, and are the screen creation instruction file 6 described above.

  Here, in order to specifically describe the difference file 6B, it is assumed that the guidance content is composed of T seconds, for example, and M frames are generated and displayed during this period (where M is an integer of 2 or more). ). Note that M is set to a number equal to or greater than the smooth display of guidance content. Further, as an example of the operation of the parts described in the component operation definition data, for example, the operation of the above-described part P1 will be described as an example. That is, the part P1 is rotated 90 degrees counterclockwise on the guidance screen 1 in T seconds. Then, the part P1 rotates counterclockwise (90 / M) ° between successive frames. As shown in this example, the screen creation instruction file generation unit 32A calculates the motion between each frame as difference information based on the description of the component motion definition data, and describes this in the difference file 6B. Specifically, after generating the initial file 6A, the screen creation instruction file generation unit 32A turns the part P1 counterclockwise (90 / M) as the creation instruction content of the second frame following the first frame. A first difference file 6B in which difference information such as rotation is described is generated. 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 generation unit 32A generates the second difference file 6B in which the creation instruction content of the third frame following the second frame is described as the 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 applies to other cases. The initial file 6A and the difference file 6B are stored in the storage unit 31.

  Thus, in the present embodiment, the initial file 6A and the difference file 6B are generated as the screen creation instruction file 6 for creating a plurality of frames constituting the guide content. However, instead of generating the difference file 6B, a file similar to the initial file 6A can be created for all frames. For example, instead of generating the first difference file 6B corresponding to the second frame, a file combining the contents of the initial file 6A and the first difference file 6B can be generated from the beginning. Since the difference file 6B is generated as in the present embodiment, it is not necessary to describe the contents that overlap between frames, so that the data storage capacity can be reduced accordingly.

  Next, the guidance content display processing by the image file generation unit 32B will be described. As shown in FIG. 9, the image file generation unit 32B first determines whether or not the display is the display of the first frame (S8). When the display is started, the first frame is displayed, that is, the first frame is displayed (S8, yes). In this case, the image file generation unit 32B is based on the initial file 6A, and the component content storage unit. A necessary component content is selected from 31A, and the first image file 8 is generated (S9). The image file 8 is an RGB file, for example. Then, the image file generation unit 32B outputs an image based on the generated first image file 8 to the display unit 33 as the first frame (S11).

  On the other hand, if the result of determination in S8 is that the display is from the first frame onwards (other than the first frame) (S8, No), the image file generation unit 32B displays the screen creation instruction data used in the previous display. Based on the data contents reflecting the contents of the difference file 6B for creating the target frame, the corresponding image file 8 is generated (S9). Here, the screen creation instruction data used in the previous display is the data of the initial file 6A or the initial file 6A and the difference file 6B used for creating the frame displayed immediately before. For example, when displaying the second frame, the screen creation instruction data used in the previous display is the data of the initial file 6A. For example, when the third frame is displayed, the screen creation instruction data used in the previous display is data of the initial file 6A and the first difference file 6B. That is, the processing is simplified and the data storage capacity is reduced by adding the contents of the difference file 6B of the display target frame to the data already used for creating the previous frame and developed in the memory.

  Subsequently, the image file generation 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 the display of all frames is completed. As described above, the image file generation unit 32B generates the image files 8 based on the generated screen creation instruction files 6 for the number of frames, and develops these image files 8 on the display unit 33 so as to be time-sequential. The guidance content (role) is displayed by displaying on the screen.

  Here, the image file generation unit 32B generates an image that matches the size of the actual guidance screen from the image file 8, and stores this image in a frame buffer (not shown) provided in the display unit 33. The display unit 33 reads the image in the frame buffer and displays it on the screen.

  It is desirable that the frame buffer has a capacity capable of storing a plurality of guidance contents. In this case, the image file generation unit 32B can store, in the frame buffer, an image group related to the guidance content to be displayed next, in addition to the image group related to the guidance content being displayed. As a result, immediately after the display of the guidance content being displayed, the image group relating to the guidance content to be displayed next can be read out and displayed sequentially, so that display switching is smooth.

  Further, the image file generation unit 32B can generate an image from the image file 8, store the image in the frame buffer, and then erase the image file 8 that has been generated. In this way, it is not necessary to store the image file 8 having a large data size after the image generation, and the data storage capacity can be greatly reduced.

  Further, in the traveling guidance of FIG. 10, four types of rolls are displayed in order for each T seconds. For example, “Nearby route guidance (English)” is displayed after “Nearby route guidance (Japanese)”. Therefore, while the image file generation unit 32B performs the processing of FIG. 9 and displays “Neighboring route guidance (Japanese)” on the display unit 33, the screen creation instruction file generation unit 32A The process shown in FIG. 8 for the “neighboring route guidance (English)” to be displayed can be performed to generate the initial file 6A and the difference file 6B. That is, an image file creation process by the image file generation unit 32B regarding the guidance content being displayed and a screen creation instruction file 6 generation process (FIG. 8) by the screen creation instruction file generation unit 32A regarding the guidance content to be displayed next (FIG. 8). Can be processed in parallel. Thus, there is no need to start display processing after waiting for generation of all the screen creation instruction files 6 for the four types of rolls, and the configuration is suitable for smoothly transitioning between the rolls.

  In FIG. 10, for example, when the train is in a running state, the image generation processing by the image file generation unit 32B related to the traveling guidance content scheduled to be displayed next to the guidance content being displayed, and the display schedule in the next station approaching state. The image generation processing by the image file generation unit 32B relating to the next station approaching guidance content can be processed in parallel. For example, during the display of “Nearby route guidance (Japanese)” of the traveling guidance content, an image generation process related to “Nearby route guidance (English)” and an image related to “Next station equipment guidance” of the next station approaching guidance content Generation processing can also be performed in parallel. Thereby, when a train state change occurs, display can be smoothly switched by giving an interrupt instruction to the image file generation unit 32B. In addition, the image group of each guidance content created by parallel processing is stored in the frame buffer as described above.

  The image file generation unit 32B, based on the initial file 6A and the difference file 6B, when the data format of the data stored in the component content storage unit 31A is, for example, so-called vector data (also referred to as vector data), An operated image file can be easily generated. However, the present embodiment is not limited to the display method using this data format.

FIG. 11 is a diagram schematically illustrating the guide content display method described above, and FIG. 12 is a diagram illustrating an example of the component content displayed in FIG. 11. FIG. 11 shows an example in which the display content of a part P that is one of the parts constituting the guidance screen 1 changes between, for example, the second to third seconds, and the displayed station names are switched.
In other words, the characters are changed from “Kasumigaseki” to “Kasugagaseki”.
FIG. 12 shows the component content 120 arranged in the part P and the component content 121 arranged in the part Q.
The component contents 120 and 121 are still image images in which “Kasugagaseki” and “Kasumigaseki” are written, respectively.

  As shown in FIG. 11, for the first frame “frame 1”, the initial file 6A describes arrangement information and the like regarding all parts, and the image file 8 is based on the initial file 6A. After the creation, a corresponding image is output on the display unit 33. Further, since there is no change in the display of the guidance screen 1 from the start 0 second to the second second, for example, the operation is not set in the difference file 6B, and the same image is output by the same image file 8 as “Frame 1”. . In the following, it is assumed that, for example, N frames are displayed per second.

  Subsequently, with respect to “frame (2N + 1)”, which is the (2N + 1) -th frame displayed after 2 seconds have elapsed, the difference file 6B used for the creation has “the transparency of part P is −α, “The transmittance of the part Q changes by + α” is described. Then, after the image file 8 is created based on the difference file 6B and the initial file 6A, an image corresponding to the display unit 33 is output. Thereafter, the operations up to “frame (3N + 1)” are as described with reference to FIGS.

As can be seen from the comparison between the display contents of the part P in FIG. 11 and the part content 120 in FIG. 12, the part content 120 is displayed from the second to the third second from the second to the second. When the transparency of the component content 120 decreases and the transparency of the component content 121 increases, the operation is defined so that the character replacement is completed in the third second.
As a result, “Kasumi is cough” is displayed.
The operation is a combination of the operations of the component content 110 in FIG. 5D (except for translation).

  As described above, according to the present embodiment, since the guidance content guide screen 1 is configured using the component content, the data storage capacity necessary for display, that is, the capacity of the storage unit 31 is set as follows. It can be greatly reduced.

  In addition, according to the present embodiment, it is possible to increase the amount of information provided to the passenger and the degree of attention compared to the case where a still image is used, and the visual appeal effect to the passenger is increased, which is more effective. Information can be provided.

  In addition, according to the present embodiment, the guide screen 1 is composed of component contents, and the arrangement and operation of the component content are defined by the component arrangement definition data and the component operation definition data. It is possible to easily cope with correction.

  In the present embodiment, since the difference file 6B is generated as a screen creation instruction file for creating the second and subsequent frames, there is no need to describe the display content overlapping between frames. Minute data storage capacity can be reduced.

  Further, the image file generation unit 32B can generate an image from the image file 8, store the image in the frame buffer, and then erase the image file 8 for which image generation has been completed. In this way, it is not necessary to store the image file 8 having a large data size after the image generation, and the data storage capacity can be greatly reduced.

  In addition, the image file generation process by the image file generation unit 32B regarding the guidance content being displayed and the screen creation instruction file generation process by the screen creation instruction file generation unit 32A regarding the guidance content to be displayed next are performed in parallel. be able to. As a result, creation of a screen creation instruction file for the next guidance content is not started after the display of the guidance content being displayed, and a period during which no guidance content is displayed does not occur.

  Further, in FIG. 10, the image generation processing related to the guidance content scheduled to be displayed next to the currently displayed guidance content and the image generation processing related to the guidance content scheduled to be displayed in the train state scheduled next to the train state are performed in parallel. Can also be done. Thereby, when a train state change occurs, display can be smoothly switched by giving an interrupt instruction to the image file generation unit 32B.

  Further, in the running guidance of FIG. 10, for example, the display content of the lower half display area of the guidance screen changes according to the guidance content, but the display content of the upper half display area does not change between the guidance contents. . For example, when the guidance content “Nearby route guidance (Japanese)” and the guidance content “Nearby route guidance (English)” are compared, the display content changes only in the lower half of the display area. Therefore, if the guidance screen is divided into a plurality of display areas and the initial file 6A and the difference file 6B are created in units of display areas, the guidance content is repeatedly displayed in units of T seconds as shown in FIG. In addition, these files relating to the display area where the display content does not change can be shared with each other. Thereby, the generation processing load of the screen creation instruction file 6 can be reduced.

  In addition, a color change can be added to the operation of the partial content. For example, as the train approaches the next station, for example, the character display may be gradually changed from black to blue to red to display the passengers with increasing attention.

  In the present embodiment, functions necessary for creating guidance content such as the screen creation unit 32, the component content storage unit 31A, the component arrangement definition data storage unit 31B, and the component operation definition data storage unit 31C are provided in the display device 30. It was set as the structure provided. Such a configuration is suitable for displaying different guidance contents for each display device 30 when a plurality of display devices 30 are provided in the vehicle.

  On the other hand, the function necessary for creating the guidance content can be provided in, for example, the branching device 21 of FIG. In FIG. 1, a plurality of display devices 30 are connected to one branch device 21. According to such a configuration, even when a plurality of display devices 30 are provided in the vehicle, the screen creation units 32 corresponding to the number of the branch devices 21 are provided, so that the cost is lower than that of the present embodiment. It becomes the composition. However, such a configuration is suitable for displaying the same guidance content on all the display devices 30 in the vehicle.

  As another configuration, a function necessary for creating the guidance content can be provided in the video information distribution apparatus 20, for example. In such a configuration, the number of installed screen creation units 32 is further reduced, so that the configuration is further inexpensive. However, the configuration is suitable for displaying the same guidance content on all the display devices 30 in the train. . In this case, the video information distribution device 20 distributes the created guidance content to the display device 30 instead of distributing the component content.

  Note that still images can be displayed according to this embodiment. That is, it is only necessary to define “no operation” for all component contents in the component operation definition data. For example, in FIG. 11, a substantially still image is displayed from the start of display to the second second.

  Further, in the guidance content of the present embodiment, the captured video is embedded in a part of the guidance screen 1, the captured video is displayed at the same timing as the frame display, and the captured video display portion is moved within the guidance screen 1 It can also be made. However, since the captured video requires a data size, it is preferable to use the data with a limited data size. Further, when such a photographed video is used, a route for transmitting data from the video information distribution device 20 to the display device 30 is divided into a case where component contents are transmitted and a case where captured images are transmitted as in Patent Document 3. It can also be configured. That is, in Patent Document 3, the captured image is transmitted directly to the display device 30 via the branch device 21 without passing through the train information device 11.

Embodiment 2. FIG.
In the first embodiment, based on the train information obtained from the train information device 11, the part content necessary for the configuration of the guidance content is selected from the part content group stored in advance in the part content storage unit 31A, and these part contents are selected. The system and method for displaying the guidance content by assembling and further adding operations have been described.

  In the present embodiment, a system and method that is information that cannot be obtained directly from the train information apparatus 11 and that displays, for example, temporary information provided from outside the train in the guidance content will be described. Here, the temporary information is, for example, operation information, accident information, or breaking news. Such temporary information is provided from the ground station 51 by wireless communication, for example.

  FIG. 13 is a diagram showing a display example of guidance content according to the present embodiment, and FIG. 14 shows an example of component content in which temporary information (for example, temporary operation information) described in text is represented as a character drawing. FIG. In FIG. 13, the part 80 for displaying the temporary information is overwritten on the display portion of the “station equipment guidance” on the guidance screen 1. 14 is selected as the part 80, and the operation of the component content 125 is defined so that characters move in the direction of the arrow shown in FIG. Thus, in the part 80, temporary operation information is displayed as a so-called telop, and the display content is displayed while moving in the direction of the arrow.

  In order to perform the display as shown in FIG. 13, the screen creation instruction file generation unit 32 </ b> A creates the component content 125 obtained by processing the contents into character drawing after the temporary information is obtained. In addition, the component placement definition data defines in advance the initial placement position of the component content created corresponding to the temporary information, and the component operation definition data contains the component content created corresponding to the temporary information. Is previously defined. FIG. 13 shows an example of the initial arrangement position and operation. The screen creation instruction file generation unit 32A relates to the created component content 125 and the component content constituting the guidance screen 1 based on the component arrangement definition data and the component operation definition data, and the initial file 6A described in the first embodiment and A difference file 6B is generated. Then, the image file generation unit 32B sequentially generates an image file for each frame based on the initial file 6A and the difference file 6B, and outputs an image corresponding to the image file to the display unit 33.

  By the way, in the display example of FIG. 13, the temporary operation information display by the parts 80 is performed in the form of being overwritten on the guidance content being displayed. Therefore, there is a problem that a part of the guidance content becomes invisible. Therefore, when displaying the temporary information, the entire guidance content being displayed is reduced and displayed in the guidance screen 1, and the part 80 is arranged in the formed blank portion. It is also possible to define an action to do In this case, although the entire guidance content is reduced and it is somewhat difficult to see, the telop display does not overwrite a part of the guidance content, so that a part of the guidance content is not displayed.

  In the above description, the temporary information is obtained from, for example, the ground station 51. However, the temporary information is input to the video information distribution apparatus 20 by a crew member or the like via a predetermined input unit on the vehicle, for example. May be. For example, a crew member can input temporary information such as a failure, an accident, or a sick person occurring in the own train to the video information distribution device 20 via an input screen of the on-board monitor device. As described above, the temporary information input on the vehicle is displayed as a telop on the guidance content in the same manner as described above, thereby providing information with higher real-time characteristics than the information from the ground station 51.

  According to the present embodiment, for example, extra information provided from outside the train or input on the vehicle is processed as character drawing into part content, and this is incorporated into a moving image of guidance content for display. Temporary information can be provided to passengers in real time. Other configurations, operations, and effects of the present embodiment are the same as those of the first embodiment.

Embodiment 3 FIG.
In the present embodiment, as a specific example of the operation of the component content, an operation that is displayed as if the part is rotating on the guidance screen by a combination of reduction / enlargement operations will be described. The configuration of the present embodiment is the same as that of the first and second embodiments, and the operation is defined in the component operation definition data.

  FIG. 15 is a diagram illustrating an example of the operation of the component content in the present embodiment, FIG. 16 is a diagram illustrating an example of the component content, and FIG. 17 is a schematic diagram illustrating the reduction direction of the parts R and S.

As shown in FIG. 15, for example, in a rectangular area on the guidance screen, the parts R and S are displayed so that the parts R and S rotate when the part R is reduced and the part S is enlarged.
Specifically, the display is switched from “Kasumi Seki” of part R to “Kasumigaseki” of part S.
In the figure, the uppermost row shows the operation start state, and the lowermost row shows the operation end state. Further, the part R is displayed based on the part content 126 of FIG. 16, and the part S is displayed based on the part content 127 of FIG.

  First, the operation of the part R will be described. In the figure, the vertical direction is referred to as a first direction, and the direction orthogonal to the first direction is referred to as a second direction. The part R is reduced in the first direction, for example, at a constant reduction speed (referred to as a first reduction speed) in a state in which the end E1 which is one end in the first direction is fixed so as not to move in the first direction. The That is, the part R is contracted in the first direction from the operation start to the operation end, and the operation is defined so that the width in the first direction becomes 0 in the operation end state. Accordingly, the end E2 which is the other end of the part R facing the end E1 moves downward at the first reduction speed, thereby forming a region where the part S is displayed above the end E2. In addition, the formation area gradually increases.

  The part R is reduced in the first direction and also in the second direction, but the reduction speed in the second direction is from 0 toward a predetermined reduction speed (second speed) from the end E2 toward the end E1. It is increasing at a constant rate. Therefore, the length of the end portion E2 remains fixed, but the length of the end portion E1 becomes shorter as time elapses, so that there is an effect of displaying with a perspective that changes with time. It looks like it is rotating downward about the second direction as the axis of rotation. In the upper part of FIG. 17, the reduction direction of the part R is schematically indicated by an arrow. Here, in order to show that the reduction speed increases as it goes downward, it is described that the size of the horizontal arrow increases as it goes downward.

  Next, the operation of the part S will be described. For convenience of explanation, the operation of the part S is defined as the reverse operation of the operation when the time is reversed from the end of the operation to the start of the operation. That is, when shifting from the operation end state in the lowermost stage in FIG. 15 to the operation start state in the uppermost stage, the part S is fixed so that the end F1 that is one end in the first direction does not move in the first direction. Thus, the image is reduced in the first direction at the first reduction speed. That is, the operation of the part S is regulated so that the part S is reduced in the first direction and the width in the first direction is 0 in the operation start state. In addition, the part S is reduced in the first direction and also in the second direction, but the reduction speed in the second direction is from 0 to the second reduction speed from the end F2 toward the end F1. It is increasing at a certain rate. As a result, the part S can also be displayed with a perspective that changes with time in the same manner as the part R. In the lower part of FIG. 17, the reduction direction of the part S when the time is reversed is schematically indicated by arrows. However, when the operation of the part S is viewed in the time positive direction, it actually corresponds to an enlargement operation. Further, as shown in FIG. 15, the end portion F2 of the part S and the end portion E2 of the part R are arranged to face each other.

  According to the present embodiment, by combining the combination of the reduction operation of the part R and the combination of the expansion operation of the part S as described above, the parts R and S can be displayed as rotating.

  Further, the present embodiment can be similarly applied not only to the case of two parts but also to the case of three or more parts. Note that it is naturally possible to display the part R or the part S alone, and in this case, the character display disappears or appears so as to rotate.

  Further, in the present embodiment, the case where the rotation direction is downward in the figure has been described, but the same applies to the case where the rotation direction is an arbitrary direction on the guidance screen.

  As described above, the present invention is useful as a video information delivery / display system and a video information delivery / display method that can increase the amount of information provided to passengers and greatly reduce the data storage capacity.
