For example, the server 500, when the number of video display devices 100 or mobile terminals 600 connected to a chatting window related to a predetermined broadcast video is 1999 and the reference value is set to 667, the first 667 chatting windows, 667 second chatting windows, and 665 third chatting windows can be controlled to be connected.

Meanwhile, the server 500 may control a first chatting window among a plurality of chatting windows to share conversation contents with a high number of likes or recommendations to other chatting windows.

For example, while the video display device 100 accesses the first chatting window and receives and displays chatting conversation contents from the server 500, the number of preferences or recommendations in the second chatting window is greater than or equal to the reference number of conversations. The content may be received from the server 500 and displayed at a specific location in the first chat window at all times. Accordingly, it is possible to share conversation contents having a large number of preferences or recommendations.

Meanwhile, the video display device 100 may vary the display speed of chatting conversation contents when the number of conversation contents input from the outside is equal to or greater than the reference number.

For example, when the number of conversation contents input from the outside is equal to or greater than the reference number, the video display device 100 controls so that one chat conversation contents are displayed every 3 seconds, and the number of conversation contents input from the outside is equal to or greater than the reference number. , If it is less than the standard number, it is possible to control so that one chatting conversation content is displayed every 5 seconds. Accordingly, the visibility of conversation content can be improved.

Meanwhile, the video display device 100 may control the display speed of chatting conversation contents to be set based on the on/off item on the chatting setting screen. Accordingly, it is possible to selectively vary the display speed of chatting conversation contents.

Although the preferred embodiments of the present disclosure have been shown and described above, the present disclosure is not limited to the specific embodiments described above, and is common in the art to which the present invention pertains without departing from the gist of the present disclosure claimed in the claims. Of course, various modifications are possible by those with knowledge of, and these modifications should not be individually understood from the technical spirit or perspective of the present disclosure.
