Automatic adjustment method for large-screen multi-path plug flow code rate

Abstract

The invention discloses an automatic adjustment method for a large-screen multi-path plug flow code rate. Synchronization of a screenshot and a plug flow of each plug flow sub-thread is controlled ina main thread; the condition that the terminal receives a same data frame when receiving the multiple plug flows is ensured; firstly, before the plug flow, a large screen initializes the threads of the multiple plug flows, and each thread manages a one-path plug flow interface; each plug flow thread is responsible for acquiring an image frame of the corresponding area of the large screen, and judges the differences between the image frame and the previous picture frame; if the change is relatively large, coding with a high code rate is performed and pushed to the terminal; if no change occurs,discarding the plug flow frame; if the change is relatively small, coding with a low code rate is performed and pushed to the terminal. According to the method provided by the invention, the large screen is cut into multiple areas to perform multi-video plug flow; the plug flow in high code rate and high frame rate manners is performed on the area with frequent activities; the frame rate and thecode rate of the plug flow in the area that acts unusually are reduced; therefore, the plug flow of the whole large screen achieves a clear and smooth effect.

Description

technical field [0001] The present invention belongs to the large-screen interface push flow technology, specifically a technology that divides the large screen into multi-channel push flow, and realizes the high-resolution, high bit rate, and high-fluency push flow of the large-screen multi-channel push flow in the active area Bit rate automatic adjustment method. Background technique [0002] Currently, in the solution of large-screen streaming, the traditional method is to capture the overall interface of the large screen for streaming. In this way, due to the relatively high resolution of large screens, the amount of data captured for one frame of image is very large, which puts a lot of pressure on hardware performance and network transmission, resulting in stuttering and unsmooth when pushing streams on large screens. Phenomenon that affects the streaming effect on the large screen. Contents of the invention [0003] The purpose of the present invention is to provi...
