Embodiment Construction

[0025] The specific implementation of the video image transmission and playing method of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] figure 1 A flow chart of a video image transmission and playing method of an embodiment is shown, including the following steps:

[0027] at the sending end;

[0028] Step S101, extract background images and moving images from each frame of images in the original video stream.

[0029] Specifically, the original video images include: real-time collected RGB video images, YUV video images, or locally stored DVD format video images, RMVB format video images, and the like.

[0030] In one embodiment, during the process of extracting moving images, a static extraction method or a dynamic extraction method may be used to extract moving object regions.

[0031] When the moving object region is extracted in a static manner, the moving image is a circumscribed rectangular image of the...

Abstract

The invention provides a method and system for transmitting and playing video images. The method comprises the following steps of: respectively extracting background images and moving images from frame images of an original video stream; calculating and recording the coordinate position of each frame moving image relative to the background images; abstracting background images from the extracted background images according to a set frame period, and recording frame positions of the abstracted background images in the original video stream; transmitting the moving images and corresponding coordinate position information of the moving images as well as the abstracted background images and corresponding frame position information of the abstracted background images; receiving the moving images and the corresponding coordinate position information of the moving images as well as the background images and the corresponding frame position information of the background images; and playing the received moving images and background images according to the frame position information and the coordinate position information. According to the method and the system, provided by the invention, the frame rate of transmitted video files is lower than that of the original video stream, the data processing amount and information capacity of video frames are reduced, and the real-time performance in video playing is improved.

Description

technical field [0001] The invention relates to video image processing technology, in particular to a video image transmission and playing method and system. Background technique [0002] There is a large amount of redundant information between adjacent frames of video images. Although the H.264 standard proposes many advanced video compression methods for video, which remove a large amount of redundant information within and between frames, these compression methods are based on high Computational complexity is the cost, and high algorithmic complexity reduces video compression and decoding efficiency, limiting real-time video transmission. [0003] In the patent document with the publication number CN100469108C, it is disclosed that a continuous video stream is generated in the local area where the information changes, and the background information that does not change only needs to be collected, stored, and transmitted once in the video conferencing system. , the amount...
