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 decoding equipment, and the method comprises: operating a UI program through a main CPU of the decoding equipment to generate acomplete UI, and segmenting the UI according to the corresponding regions of the complete UI on all output channels of the decoding equipment; sending the segmented UI data to display caches of CPUs corresponding to the output channels respectively, wherein the sent segmented UI data carries a timestamp of the main CPU; and enabling the CPU corresponding to each output channel and the main CPU ofthe main equipment to be subjected to time synchronization, and synchronously displaying and outputting the respectively received UI user interface data onto the corresponding spliced screen. The synchronous display effect of the UI is ensured through double time synchronization mechanisms, the limitation that one device can only display the UI at one output port is broken through, the display ofthe UI is expanded to a plurality of output channels, the display area of the UI image is expanded, and the display effect of the UI image is improved.

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...
