Embodiment Construction

[0024] The technical solution of the present invention will be described in further detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, and not to limit the present invention.

[0025] figure 1 Shown is a structural diagram of a video rendering system according to an embodiment of the present invention.

[0026] Among them, the video rendering system of the embodiment of the present invention includes a rendering unit 1, a calculation unit 2, an image storage unit 3;

[0027] Among them, the storage unit 3 is used to store multiple sets of image frame data of the video to be drawn. Wherein, the multiple groups refer to at least two groups. In this embodiment, three sets of image frame data are taken as an example for description. Among the three sets of image frame data, the first set of image frame data may include 100 frames of images, the second set of image...

Abstract

The invention relates to a video drawing system. The video drawing system comprises a drawing unit, a calculation unit and an image storage unit; the image storage unit is used for storing at least two groups of image frame data, wherein each group of image frame data comprises a frame image; the drawing unit is used for drawing at least two groups of corresponding videos according to the at leasttwo groups of image frame data stored in the image storage unit, wherein each group of image frame data corresponds to one video window; the calculation unit is used for calculating the position coordinate of the vertex of each video window in real time and determining the shielded proportion of each video window according to the coordinate position; and the drawing unit also adjusts the drawingframe rate of the video window according to the shielded proportion of the video window. Through the invention, the occupancy rate of the CPU can be reasonably reduced under the condition that CPU resources are limited, the image processing speed of the CPU is greatly improved, the overall drawing time is shortened, the overall drawing frequency is reduced, and drawing of the frame image is completed more quickly.

Description

Technical field [0001] The invention relates to the field of image processing, in particular to a video rendering method and system. Background technique [0002] At present, with the rapid development of Internet technology, remote network teaching, remote network monitoring, remote video conferencing, remote data sharing, etc. have been widely used in daily life. These applications greatly facilitate users to communicate and communicate over long distances, and in these applications, the sender needs to transmit each frame of the screen in real time, and then the receiver needs to receive and store these multiple frame images locally and then use a certain amount of The frame rate is drawn into a video animation and displayed. When data from multiple sending ends needs to be sent to the same receiving end, multiple video animations from multiple sending ends will be displayed on the receiving end at the same time. Because the video drawing operation requires a lot of CPU proc...
