A video playback system and related devices for jointly displaying videos on multiple screens

Abstract

The invention provides a multiscreen video playing system dynamically generating scaled videos, and a related device. The system comprises a video playing device with a main display, portable communication devices with screens, and a multiscreen display control server. The multiscreen display control server transmits contents of a target video to the video playing device through a network, and the video playing device uses the main display to display the target video. In a process that the main display displays the target video, if the multiscreen display control server receives selection information corresponding to positions of local regions in the main display, the multiscreen display control server would dynamically generate scaled videos corresponding to images displayed in the local regions, and transmits contents of the scaled videos to the portable communication devices through the network, so that the portable communication devices can synchronously display the scaled videos using screens. Using the portable communication devices to display the scaled videos, content integrity of the target video displayed by the main display can be maintained.

Description

technical field [0001] The present invention relates to a video playing system, in particular to a video playing system and a related multi-screen control device which jointly display videos through multiple screens. Background technique [0002] With the advancement of technology, portable communication devices capable of connecting to the Internet and displaying videos, such as smart phones, tablet computers, and handheld game consoles, are becoming more and more popular. In order to take into account the convenience of portability and use, the size of the screen that can be mounted on the portable communication device is very limited, so it cannot provide a larger display screen for users to watch. [0003] In the related art, a plurality of screens can be pre-connected to a computer host with signal lines to form a video-wall system that can jointly display the same video through the plurality of screens. The video signal to be displayed on the traditional video wall sy...

Problems solved by technology

Therefore, the number, size, and placement of the screens in the TV wall must be configured in accordance with the format of the video signal in the computer host, and cannot be changed flexibly.

[0004] However, different portable communication devices may have screens of different sizes and may use different operating systems

If you want to use the framework of the traditional video wall system to connect multiple portable communication devices to jointly display the same video, it is necessary to set limits on the number, screen size, operating system, and placement of portable communication devices , making it impossible for users to flexibly match various portable communication devices according to their preferences to jointly display the same video

In this way, the convenience and flexibility of use will be seriously reduced, and the user's acceptance and application range will be reduced.
