Description

TECHNICAL FIELD [0001] The present invention relates to a video streaming system for a railway vehicle, and a railway vehicle including the same. BACKGROUND ART [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video streaming system for a railroad car and a railroad car including the same. More particularly, the present invention relates to a video streaming system for a railroad car, And a railway vehicle including the same.

The camera and the monitor of the railway vehicle broadcasting system are connected to a ring network constituted by an Ethernet switch. In this network configuration, cameras and other images can be checked through a monitor fixed at a specific location. Therefore, since it is difficult to confirm the camera image while the crew of the railway vehicle is moving, it is difficult to expect an immediate response to emergency situations such as fire and accidents. In addition, the passenger of the railway vehicle views the image only by the designated monitor, and thus the convenience is reduced.

In addition, a video transmission service may cause a load on the network, which may result in degradation of image quality such as image delay and omission, and other system function errors.

The camera 120 is installed in the railway vehicle and can photograph the set area. In addition, the camera 120 may process the photographed image to generate camera image data. In addition, the camera 120 may connect to the network and transmit camera image data to at least one of the streaming server 140 and the control unit 150 through the network.

The display unit 130 may be installed at a predetermined position of the railway vehicle. Also, the display unit 130 can connect to the network 110 and receive image data through the network 110. [ Also, the display unit 130 can output the received image data. Here, the display unit 130 may include various means for displaying images such as a cathode ray tube, a liquid crystal display, an organic light emitting display, and a plasma display.

The streaming server 140 may store first service image data for providing a viewing service. In addition, the streaming server 140 may receive camera image data from the camera 120. [

The streaming server 140 may provide the display unit 130 with the first service video data. In addition, the streaming server 140 may receive at least one of the camera image data and the first service image data by receiving the video streaming request from the mobile terminal 300 and classifying the authority of the user of the mobile terminal 300 .

Specifically, the streaming server 140 may provide the first service video data to the display unit 130 under the control of the controller 150. [ When the streaming server 140 receives the video streaming request from the mobile terminal 300, the streaming server 140 classifies the streaming service level by authenticating the user information through the mobile terminal 300, And provide the camera image data and the first service image data to the terminal 300. Also, the streaming server 140 may provide only the first service image data to the mobile terminal 300 of the second class among the streaming service classes.

Here, a video streaming method of the streaming server 140 will be described with reference to FIG.

3 is a flowchart illustrating a video streaming method of a streaming server according to an embodiment of the present invention.

First, the streaming server 140 may receive a video streaming request from the mobile terminal 300 (S110).

Next, the streaming server 140 requests identification information and a password from the mobile terminal 300 to receive the identification information and the password from the mobile terminal 300 in order to provide the video streaming service (S120).

Next, the streaming server 140 may identify the streaming service class of the mobile terminal 300 by verifying the identification information and the password received from the mobile terminal 300 (S130).

Through the verification, the streaming server 140 can confirm the streaming service level of the user of the mobile terminal 300 according to the identification information. Here, the streaming service class may be classified into the first class and the second class.

Next, the streaming server 140 may provide the streaming service to the mobile terminal 300 according to the checked streaming service class.

If the streaming service level of the user of the mobile terminal 300 is the first level, the streaming server 140 determines that the user of the mobile terminal 300 is a flight attendant and transmits the first service image data And camera image data.

The mobile terminal 300 receiving the first service image data and the camera image data can output one of the first service image data and the camera image data as an image according to the user's selection. A user of the mobile terminal 300 can view an image of one of the first service image data and the camera image data through the mobile terminal 300. At this time, the user of the mobile terminal 300 can view the real-time situation in the railway car by watching the image by the camera image data.

In addition, when the streaming service class of the user of the mobile terminal 300 is the second class, the streaming server 140 may provide the first service image data to the mobile terminal 300. The mobile terminal 300 receiving the first service image data can output the first service image data as an image. The user of the mobile terminal 300 can view an image based on the first service image data. At this time, the user of the mobile terminal 300 can view an image while moving.

The streaming server 140 may provide the first service image data to the display unit 130 through the network 110 in a wired manner. In addition, the streaming server 140 may provide the first service image data to the mobile terminal 300 via the network 110 or directly in a wireless manner.

Referring back to FIG. 2, the controller 150 may control the camera 120, the display unit 130, and the streaming server 140. For example, the control unit 150 can control shooting of the camera 120, video display of the display unit 130, streaming service of the streaming server 140, and the like.

In addition, the controller 150 may store the second service image data to back up data for the viewing service. Also, the controller 150 may compare the first service video data and the second service video data and synchronize them.

Here, the synchronization method of the control unit 150 will be described with reference to FIG.

4 is a flowchart illustrating a synchronization method of a controller according to an embodiment of the present invention.

First, the control unit 150 may request the streaming server 140 to store the service video data (S210).

Next, the control unit 150 can compare the service image data received from the streaming server 140 with the stored service image data (S220).

Here, the controller 150 may compare the first service image data and the second service image data.

If the first service image data and the second service image data are not the same, the controller 150 may synchronize the service image data (S230).

The control unit 150 may back up and store the first service video data, and may restore the first service video data using the second service video data stored when the streaming server 140 is abnormal.

Meanwhile, the first service image data or the second service image data may include at least one of a movie, a TV broadcast, and an advertisement.

The present invention can improve the viewing convenience of the passenger because the passenger can view not only the fixed display but also the camera image or other image provided by the railway car to his or her mobile device.

In addition, the present invention can improve the safety of a passenger because the crew can view an image of a camera or other images with a device carried while the passenger is moving and cope with an emergency immediately.

Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. In addition, it is a matter of course that various modifications and variations are possible without departing from the scope of the technical idea of the present invention by anyone having ordinary skill in the art.
