Problems solved by technology

[0004] However, the inventors of the present invention have found that in the prior art, with the high-definition of the video surveillance industry, more and more high-definition videos have entered the scope of management, and the decoding of high-definition videos requires a powerful CPU. With continuous growth, the number of images that need to be decoded and displayed continues to increase, which will reduce the CPU processing speed, affect the speed and quality of decoding and display, and cause users to be unable to browse the screen in time according to actual needs

Abstract

The invention relates to the field of video monitoring, and discloses a multi-picture image decoding display method and a video monitoring terminal. By the method and the terminal, an image is played back by selecting a proper code stream according to the logic size of the image, so the consumption of a central processing unit (CPU) in the video decoding of the terminal is reduced, and the definition and smoothness of the image are further ensured. Particularly for multi-picture splitting conditions, the effect of reducing the consumption of the CPU is more remarkable.

Description

technical field [0001] The invention relates to the field of video monitoring, in particular to a technique for decoding and displaying images of a video monitoring terminal. Background technique [0002] At present, in the video surveillance industry, the screen segmentation mode is generally used, and the performance of the Central Processing Unit ("CPU") of the personal computer (Personal Computer, "PC") is increasingly high, and multiple images are decoded and displayed at the same time. Realize the functions of contrast monitoring, synchronous monitoring and tracking monitoring between images. Screen segmentation refers to dividing the display screen into multiple display blocks for image decoding and display within the logical range according to the logical dot matrix of the display screen at the application software layer. [0003] In the multi-image decoding and display mode of realizing picture division, the prior art mainly adopts such as figure 1 The method show...
