Abstract

The present invention provides a video information delivery and display system including display devices respectively mounted on cars of a train 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, and a guidance-screen creating unit configured to select, according to a guidance content displayed on the guidance screen, based on train information, 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 part arrangement definition data, and cause the part content to act according to part action definition data to thereby cause the display units to display the guidance content.

First claim

The invention claimed is:

1. A video information delivery and display system comprising:
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 plurality of part contents, each of the part contents 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 relative to other contents on the guidance screen;
a part-action-definition-data storing unit configured to store part action definition data for individually defining an action of the part content itself on the guidance screen; and
a screen creating unit configured to select; according to a guidance content displayed on the guidance screen, based on a train state which has been determine based on the train information obtained from the train information devices, one of the part contents 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, sequentially create, for each of a plurality of continuous frames in time series obtained by changing little by little the arranged part content on the guidance screen according to the part action definition data, image files serving as sources of creating the frames, display the frames based on the image files on the display units in time series, and erase the image files from a memory after the display.

2. The video information delivery and display system according to claim 1 , wherein a number of frames created by the screen creating unit in one second is set to a number for making the display in time series of the guidance content on the display units smooth.

3. A video information delivery and display system comprising:
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 plurality of part contents, each of the part contents 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 relative to other contents on the guidance screen;
a part-action-definition-data storing unit configured to store part action definition data for individually defining an action of the part content itself on the guidance screen; and
a screen creating unit configured to; select, according to a guidance content displayed on the guidance screen, based on a train state which has been determined based on the train information obtained from the train information devices, one of the part contents 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, sequentially create, for each of a plurality of frames continuous in time series obtained by changing little by little the arranged part content on the guidance screen according to the part action definition data, image files serving as sources of creating the frames, and display the frames based on the image files on the display units in time series, and erase the image files from a memory after the display.

4. The video information delivery and display system according to claim 1 , wherein the action of the part content includes at least one of a moving action, a rotating action, an expanding or reducing action, an appearing or disappearing action, and a change in a color.

5. The video information delivery and display system according to claim 1 , wherein the screen creating unit creates, based on initial arrangement information on the guidance screen of the part content obtained from the part arrangement definition data and initial information of the action of the part content obtained from the part action definition data, a first frame using the part content and creates frames after the first frame formed by causing the part content to act little by little on the guidance screen according to the part action definition data.

6. The video information delivery and display system according to claim 5 , wherein the guidance-screen creating unit includes:
a screen-creation-instruction-file generating unit configured to generate a plurality of screen creation instruction files in which creation instruction contents of the frames included in the guidance content are respectively described; and
an image-file generating unit configured to generate the frames based on the screen creation instruction files.

7. The video information delivery and display system according to claim 6 , wherein the plurality of screen creation instruction files include an initial file in which a creation instruction content necessary for creation of the first frame, which is an initial screen of the guidance content, is described and difference files respectively generated for the remaining frames excluding the first frame, creation instruction contents of the difference files being difference display contents between the frames and frames immediately prior to the frames.

8. The video information delivery and display system according to claim 7 , wherein the screen-creation-instruction-file generating unit determines, according to the guidance content, based on the train information, the part content used for the formation of the guidance screen from the part-content storing unit, generates the initial file for creating the first frame by acquiring initial arrangement information on the guidance screen of the part content referring to the part arrangement definition data and acquiring initial information of the action of the part content referring to the part action definition data, and creates the difference file referring to the part action definition data.

9. The video information delivery and display system according to claim 7 , wherein the image-file creating unit determines whether display of the guidance content is display of the first frame, when the display of the guidance content is the display of the first frame as a result of the determination, after selecting, based on the initial file, the part content used for the formation of the guidance screen from the part-content storing unit and generating an image file, outputs an image based on the generated image file to the display units as the first frame, and, when the display of the guidance content is display of a frame after the first frame as a result of the determination, after generating an image file corresponding to the display target frame using data obtained by reflecting a content of the difference file for creating the display target frame on data used for creation of a frame immediately prior to the display target frame, outputs an image based on the generated image file to the display units as the display target frame.

10. The video information delivery and display system according to claim 6 , wherein, after storing an image generated from the image file in frame buffers of the display devices, the image-file generating unit erases the image file.

11. The video information delivery and display syst
