Embodiment 1

[0035] This embodiment provides a method for compressing and transmitting video stream files, such as figure 1 shown, including steps:

[0036] S11: Acquiring the current image information of the video and the image information of the video image within a preset period;

[0037] S12: Comparing the image information of the video frame within the preset period with the image information of the current video frame, and acquiring a frame area whose image color scale difference is greater than a preset threshold;

[0038] S13: Reserving the picture image areas whose image color scale difference value is greater than a preset threshold value within a preset period, and replacing the picture image areas whose image color scale difference value is smaller than a preset threshold value.

[0039] In this embodiment, before step S11, it also includes:

[0040] Step S101: Obtain current terminal network status information;

[0041] Step S102: Determine whether the network status matche...

Embodiment 2

[0059] This embodiment provides a system for compressing and transmitting video stream files, such as figure 2 shown, including:

[0060] Picture image acquisition module 22: used to acquire the current picture image information of the video and the video picture image information in the preset period;

[0061] Image level comparison module 23: used to compare the image information of the video picture within the preset period with the image information of the current video picture, and obtain the picture area whose image color level difference is greater than the preset threshold;

[0062] Picture processing module 24: for retaining the picture image areas whose image color scale difference value is greater than the preset threshold value within a preset period, and replacing the picture image area whose image color scale difference value is smaller than the preset threshold value.

[0063] In this embodiment, the preset period is the residence time of human visual illusions....

Abstract

The invention provides a method and a system for compression and transmission of a video streaming file, and the method and the system are used for solving a problem of poor video play quality and influence on user experience caused by compression through reduction of video content image quality. The method comprises the following steps: S1: acquiring current screen image information of a video and video screen image information within a preset period; S2: comparing the video screen image information within the preset period with the current video screen image information, acquiring a screen region of which an image color gradation difference value is greater than a preset threshold value; S3: reserving the screen region of which the image color gradation difference value is greater than the preset threshold value within the preset period, and substituting the screen region of which the image color gradation difference value is less than the preset threshold value. With the method andthe system provided by the invention, according to duration of stay of human visual illusion, processing video images within a stay period, bit rate of a streaming media file is reduced, network resource is saved, and visual experience of users is guaranteed.

Description

technical field [0001] The invention relates to the technical field of video transmission processing, in particular to a method and system for compressing and transmitting video stream files. Background technique [0002] When the video is transmitted in real time, the video quality level can be set, and the video quality can be divided into 5 levels, which are high-definition video conferencing (HDTV), studio-quality digital TV, broadcast-quality TV, VCR-quality TV and video conference quality. [0003] When the network bandwidth is limited or the Internet tariff is high, the user generally requests the server to compress the quality of the video content to obtain a video file with a lower video quality level, thereby avoiding video transmission due to too large video content. In the process, there will be a problem of high tariffs, but the playback quality of the video will also be poor, which will affect the user experience. [0004] Visual illusion refers to the creatio...
