Embodiment Construction

[0044] The present invention will be further described below in conjunction with the accompanying drawings.

[0045] like figure 1 As shown, a Netty-based distributed screen rendering and screen playback control method, including player screen distributed rendering display, player screen control action synchronization and screen control data synchronization;

[0046] The distributed rendering display of the player screen is based on the split-screen rendering of the same screen by several players to realize the overall display of the screen on a large screen (resolution above 10,000). The location and size of the screen and the content of the area where the monitoring screen is displayed, so that several players can display a monitoring screen;

[0047] Player screen control action synchronization is used to broadcast the interactive actions on the screen to all distributed players, so that after the distributed player receives the action synchronization command, it will exec...

Abstract

The invention discloses a distributed picture rendering and picture playing control method, which comprises the following steps: a player monitors a picture distributed rendering display, a player monitors a picture control action synchronization and a picture control data synchronization; the player monitors a picture control action synchronization and a picture control data synchronization. Theinvention provides a distributed playing software system of a large screen visualization platform. Through an asynchronous, event-driven network application framework, control commands and control data are pushed directly to the client, the real-time synchronization of control actions and data of distributed player software pictures is realized, and the problem of picture rendering and synchronization when super-resolution or multiple graphics workstations display the same picture is effectively solved.

Description

technical field [0001] The invention relates to a Netty-based distributed picture rendering and picture playing control method, which belongs to the field of image processing. Background technique [0002] In the prior art, as far as the large-screen hardware system is concerned, it is generally composed of a graphics workstation, a splicing controller and a large screen. In this mode, the player software playback mode is a single-screen mode, and the software program runs on a On the graphics workstation host, the entire content of the monitoring screen is displayed through full-screen mode rendering. However, as the size and resolution of large screens continue to increase, a single graphics workstation is not enough to support the entire large-screen image display. The traditional method is to stretch the image signals of the graphics workstation through the splicing controller, and the output of the graphics workstation The image signal covers the large screen area, but...
