Embodiment 1

[0063] figure 1 It shows the implementation flowchart of the video coding method provided by Embodiment 1 of the present invention. For the convenience of description, only the parts related to the embodiment of the present invention are shown, and the details are as follows:

[0064] In step S101, the focus point of the user's eye on the video screen is detected.

[0065] In the embodiment of the present invention, the user terminal uses a stereo camera to shoot the user, and obtains the three-dimensional position of the user's eyeball relative to the display screen, and then detects the posture angle of the user's eyeball to determine the focus point of the user on the video screen, and finally sends The information of the focal point is sent to the video acquisition terminal. It should be noted that the display screen is a display screen of the user terminal, and video images are displayed on the display screen.

[0066] In step S102, the collected video image is divided ...

Abstract

The invention is suitable for the technical field of video coding and decoding, and provides a video coding and decoding method and system. The video coding and decoding method comprises the following steps of: before network video coding, obtaining a focusing point of a user eyeball on a video picture, zoning a video image according to the focusing point; then dividing the video image into at least two independent video images according to frames of the divided images, reducing the independent video images according to a proportion one by one; and finally, carrying out video coding on the reduced independent video images. Subsequently, the system can execute corresponding decoding according to the treatment before video coding. According to the invention, the definition of the video image near the focusing point of the user eyeball can be effectively maintained, and the data volume of the un-attended video image is reduced. Meanwhile, the invention has the advantages of labor cost saving, lower requirement of a computing capacity of a processor, simple and easy operation, and high efficiency.

Description

technical field [0001] The invention belongs to the technical field of video encoding and decoding, and in particular relates to a video encoding and decoding method and system. Background technique [0002] Due to the huge amount of video data and the limited network bandwidth, video generally needs to be compressed to reduce the amount of data transmission during network transmission. The current network video compression methods are all one-way, and do not perform compression processing according to the status of the user watching the video. [0003] The human visual system generally only has a clear field of vision at about 2 degrees from the center point, and images outside this angle will become blurred as the angle increases. Most of the blurred image parts are filled with details through the memory of the human brain, so as to reconstruct the entire image in the mind. Therefore, the amount of data in the video at each moment is much higher than the amount of data t...
