Embodiment Construction

[0034] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, and the following embodiments do not constitute a limitation of the present invention.

[0035] The general idea of ​​the present invention is to break through the existing technology of using a computer to make a UI and output it to a large display screen, using a decoder to realize ultra-high-definition video decoding, and displaying labels on the decoder. However, there is a difficulty in the implementation of the decoder solution. It is difficult to realize the label information across multiple splicing screens through the traditional UI implementation method, and it is very easy to overlap or lack data on the dividing line of the splicing screens. The present invention solves the problems of how to present UI information across CPUs and how to solve the problem of cross-screen label display between splicing screens....

Abstract

The invention discloses a user interface distributed display method and a decoding device. The main CPU of the decoding device runs a UI program to generate a complete UI user interface, and divides the UI according to the corresponding areas of the complete UI user interface on each output channel of the decoding device. User interface: send the divided UI user interface data to the display cache of the CPU corresponding to each output channel respectively, and carry the time stamp of the main CPU in the sent divided UI user interface data; the CPU corresponding to each output channel and The main CPU of the main device performs time synchronization, and synchronously displays and outputs the received UI user interface data to the corresponding splicing screen. The present invention guarantees the synchronous display effect of the UI through a dual time synchronization mechanism, breaks through the limitation that a device can only display the UI at one output port, extends the display of the UI to multiple output channels, expands the display area of ​​the UI image, and improves The display effect of the UI image.

Description

technical field [0001] The invention belongs to the technical field of video decoding, and in particular relates to a user interface distributed display method and decoding equipment. Background technique [0002] Video surveillance is an important part of the security system, and it is widely used in many occasions because of its intuition, accuracy, timeliness and rich information content. In recent years, with the rapid development of computer, network, image processing and transmission technology, the popularization trend of video surveillance has become more and more obvious. [0003] In the monitoring centers of many video surveillance systems, video walls (or large display screens) are deployed to centrally display monitoring scenes, such as command centers based on AR real-world maps. Generally speaking, on the large display screen of the monitoring center, a user interface (UI) is often superimposed on the video image. The user interface UI includes information sup...
