Description

Video display system

The present invention relates to a video display system that can be used in a passenger seat in a moving body such as an aircraft or a train, and more particularly to a technique for displaying a good caption language for a plurality of passenger seats.

In recent years, an example in which an image / audio distribution system is installed in a moving body such as an aircraft and an information distribution service is provided for seat terminal devices installed in passenger seats has become widespread. This system usually includes a seat terminal device that is viewed and operated by a passenger in a seat, and a shared monitor that is shared by a plurality of passengers and operated by a flight attendant, and the seat terminal device and the shared monitor are subtitles associated with the video. The function to display is provided. With regard to subtitles, it is required to display a plurality of languages, but selection of the optimal language has become an issue. That is, for the seat terminal device of each seat, it is possible for the passenger to select the language that suits him / herself, but for the shared monitor, it is necessary to support viewing from passengers in multiple seats, It includes various factors such as viewing conditions related to the position of the arrangement. For this reason, it is necessary to display a language that can be viewed by as many passengers as possible.

As a conventional technique for dealing with this problem, a broadcast receiving device capable of displaying a plurality of subtitles, a DVD (Digital Versatile Disc) playback device, a subtitle display system for transmitting desired subtitle information for each theater seat, and the like have been proposed. (For example, refer to Patent Documents 1 to 3), and an announcement system for passengers in an aircraft discloses a technique related to multilingual communication in which a passenger can select a plurality of languages (for example, Patent Document 4). reference).

However, conventionally, a shared monitor that is viewed by a plurality of passengers has been set by a crew member, and an optimal subtitle language cannot always be selected. In addition, viewing conditions of the shared monitor differ depending on the seating position and the like, and language display that is easy to read for many passengers cannot be performed.

Furthermore, the conventional method of selecting the announcement language based on the language information from the passenger and distributing it throughout the aircraft is a common monitor when the information provision area is divided and multiple shared monitors are used. There is no function to select and provide a language for each, and improving the language display on the shared monitor is an important issue.

FIG. 9 is a flowchart showing a subtitle display procedure in the present system 1.

In this system 1, as shown in FIG. 4, the shared monitor 50 is connected to the server device 10 via the control device 20, and receives information related to video, a plurality of sounds, a plurality of subtitles, and the like from the server device 10. The information is provided to the passengers of each seat in the information providing area 100. At this time, the control device 20 receives information such as language information from the server device 10 and the seat terminal device 40, and receives information related to the display of subtitles on the shared monitor 50 (hereinafter abbreviated as “subtitle display information”). Generate.

Hereinafter, the procedure until the subtitles are displayed on the shared monitor 50 will be described with reference to FIG.

First, in the system 1, when the operation related to the display of subtitles on the shared monitor 50 starts (step S <b> 1), the language information collection unit 21 of the control device 20 causes the passenger to use his / her seat in each seat terminal device 40. In order to specify the display language to be used, it is confirmed whether information relating to the language (hereinafter abbreviated as “seat language information”) has been input (step S2). When the seat language information has been input, the input information transmitted from the seat terminal device 40 is received and used. When the seat language information is not input, a predetermined standard language is used.

Next, the display language selection unit 22 of the control device 20 aggregates the seat language information received from each seat terminal device 40 and shares based on the aggregation result of the seat language information and the provision area information related to the shared monitor 50. Language information to be displayed on the monitor 50 (hereinafter abbreviated as “monitor language information”) is selected (step S3), and the requirement (seat information) related to language display is added to generate caption display information ( Step S4). Thereafter, instruction information related to subtitle display is transmitted to the shared monitor 50 based on the generated subtitle display information (step S5). The shared monitor 50 performs output (display) based on the instruction information received from the control device 20 (step S6).

When subtitles are displayed on the shared monitor 50, the language information collection unit 21 of the control device 20 checks whether or not there is a change in seat language information counted from each seat terminal device 40 at a predetermined interval (step S7). When the seat language information changes (in the case of “Yes”), the process returns to step S2, the seat language information is confirmed, and the following procedure is performed. If there is no change in the seat language information (in the case of “No”), the setting of subtitle display on the shared monitor 50 is continued as it is, and the control operation related to subtitle display in the control device 20 is ended (step S8).

When there are a plurality of languages generated as monitor language information, the control device 20 sets a plurality of languages for the shared monitor 50, and the shared monitor 50 displays a plurality of subtitles.

Next, a method for generating monitor language information will be explained using examples.

FIG. 5 shows that the number of seats in the information provision area A is 16, the number of languages that can be displayed on the seat terminal device 40 and the shared monitor 50 is 3, and the breakdown of the seat language information received from the seat terminal device 40 is Japanese 9. The case of English 6 and Chinese 1 is shown. In this example, a threshold is used for generating monitor language information to be displayed on the shared monitor 50. The threshold value is calculated as the number of seats divided by the number of languages (16 ÷ 3≈5), and Japanese and English, which are designated as numbers greater than or equal to the threshold, are selected and set as the display language of the shared monitor 50.

FIG. 6 shows an example in which priority is set in advance for each seat, and a language to be displayed on the shared monitor 50 is selected using this priority information. Priorities are quantified based on “ease of viewing”. In this example, priorities 2 to 5 relating to the visibility of the shared monitor 50 are given according to the arrangement position of each seat. In the information provision area B, the number of seats is 16, the number of languages that can be displayed on the seat terminal device 40 and the shared monitor 50 is 3, and the breakdown of the seat language information received from the seat terminal device 40 is Japanese 9, English 6, Chinese 1. In this case, the acquisition point for each language is calculated by multiplying the seat language information of each seat by the priority, and Japanese 38, English 22, and Chinese 2 are obtained. The threshold value is calculated as total acquired points (62) ÷ number of languages (3) ≈21, and Japanese and English, which are designated as the number more than the threshold value, are selected and set as the display language of the shared monitor 50 Do.

Note that when “easy to see (visibility)” is used as a priority criterion, a method such as “in front”, “not too close”, or “not too far” may be used as a determination item.

Next, in the shared monitor 50, when selecting and outputting (displaying) the subtitle language accompanying the video based on the monitor language information received from the control device 20, an example of adding requirements related to language display is shown in FIG. A description will be given using 7A and 7B.

7A and 7B are examples corresponding to the tabulation result of seat language information by changing the size and display position of the subtitles, and are set to the seat so that it can be easily seen from a seat far from the shared monitor 50. The case where the subtitle size of the language is increased or the subtitle is displayed in the upper part is shown.

FIG. 7A is an example in which the subtitles in the language specified in the rear seat are displayed in the upper row, and since many Japanese are specified in the rear seats (second and third rows), Japanese subtitles are displayed. It is displayed in the column above the shared monitor 50. FIG. 7B is an example in which the subtitles in the language specified in the rear seat are displayed in large size. Since many Japanese are specified in the rear seats (second and third columns), the English subtitles are displayed in English subtitles. On the other hand, Japanese subtitles are displayed larger.

Next, application examples related to the configuration of the system 1 will be described with reference to FIG.

FIG. 8 shows a case where the system 1 includes a plurality of information providing areas which are service providing areas. This example shows a case where the information providing area 100 (FIG. 1) in the aircraft is divided to provide, for example, five information providing areas A to E. For the shared monitor 50, four small information providing areas A to D and shared monitors 51 to 54 are provided inside the information providing area E. The information providing areas A to D are set corresponding to the shared monitors 51 to 54, respectively. The information providing areas A to D may overlap each other. In a seat in an overlapping area, good visibility can be obtained by using a shared monitor in another area. Further, the shared monitors 51 to 54 generate monitor language information from the respective provided area information and seat language information, generate subtitle display information by adding requirements related to language display, and share the monitors 51 to 54. Set to, and output (display).

In the above embodiment, the seat terminal device 40 equipped with a personal display monitor is installed on the back of the passenger's seat, and the passenger can view the distribution video on the personal display monitor. The seat terminal device 40 is not installed on the back of the seat shown in FIG. 10A, and the passenger may watch the video on the shared monitor 50 (not shown) and listen to only the sound through the headphones 41. In this case, a seat terminal device (individual viewing unit) not equipped with a personal display monitor is installed below the seat (not shown), and the headphones 41 are connected to the seat terminal device. Also, since there is no personal display monitor in front of the passengers, a controller 42 is provided for selecting content and viewing language. The controller 42 is also connected to the seat terminal device. FIG. 10B is an enlarged view of the controller 42, and the passenger may select the content and the viewing language by operating the keys of the operation unit 44 while confirming the display contents of the display panel 43 of the controller 42.

In the above-described embodiment, it is assumed that all passengers are viewing the seat terminal device 40. However, the seat is vacant or the passenger is turned off without wishing to view the seat terminal device 40. In some cases, seat language information cannot be collected, and the priority and threshold value of the display language may be set except for those seats.

As described above, when the video display system 1 according to the present embodiment is used, information related to the language specified in the plurality of seat terminal devices 40 is collected and displayed on the shared monitor 50 based on the collected seat language information. It is possible to display the subtitles on the shared monitor 50 by determining the language to be used and adding requirements such as visibility related to the language display. Therefore, in the shared monitor 50, it is possible to display a language with excellent visibility reflecting the actual usage in the plurality of seat terminal devices 40.
