Embodiment 1

[0068] The present invention discloses a large-screen splicing method based on multiple PCs that can be infinitely enlarged. The synchronization of each part of the image ensures the quality of the spliced ​​video image.

[0069] figure 1 As the basic framework of the present invention, the present invention discloses a multi-PC-based large-screen splicing method that can be infinitely enlarged, and the method includes the following steps:

[0070] [Step 1] Send the same video stream to multiple PC decoding terminals connected through the network, and ensure the data is sent synchronously by means of UDP multicast transmission.

[0071] Connect multiple PC decoding terminals and video sources through the network, and each PC terminal controls one or more monitors in the large screen. Under the supported size and resolution, the monitors that the PC terminal can control can be freely combined. The number of blocks, sizes and resolutions of the monitors controlled by the PC te...

Abstract

The invention discloses large screen splicing method and system, wherein the method comprises the following steps of: A, transmitting the same video stream to a plurality of PC (Personal Computer) decoding terminals connected through a network to ensure the synchronous transmission of data through the modes of UDP (User Datagram Protocol) multicasting transmission and the like; B, carrying out delay regulation on each PC decoding terminal through NTP (Network Time Protocol) clock synchronism and frame timestamp to ensure the image quality of a spliced large screen; and C, cutting and displaying part of the image by using each PC decoding terminal to ensure that the image of the spliced large screen is integral and non-overlapped. The invention realizes the infinite amplification on splicing the large screen through the infinite expansion of the PC terminal, realizes the flexible changes of the splicing size and the resolution ratio of the large screen through the arbitrary combination of the PC decoding terminals and ensures the synchronism of each part of the image of the spliced large screen as well as the uniformity and the continuity of the whole image through video delay regulation.

Description

technical field [0001] The invention belongs to the field of video display technology, and relates to a video splicing method, in particular to a multi-PC-based large-screen splicing method that can be infinitely enlarged; meanwhile, the present invention also relates to a system of the above-mentioned large-screen splicing method. Background technique [0002] In a video display system, especially in a high-definition video display system, in order to better display the detailed effect of the video image, the video image is often enlarged and then played. Due to the limited size and resolution of a single display, it cannot meet the actual needs. However, the large-screen splicing technology splices multiple displays into a large screen, and the size and resolution of the screen are doubled. Using the spliced ​​large screen to play a video, the image has a higher magnification, and the display of the details is clearer. [0003] The existing large-screen splicing technolog...
