Embodiment Construction

[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0051] figure 1 It is a schematic flowchart of an embodiment of the video data compression method of the present invention. Such as figure 1 Shown, the compression method of video data of the present invention comprises:

[0052] Step S100, collecting video images. In a specific implementation, the desktop video image may be collected in step S100. For example, when the user performs remote control on the second computer from the first computer, the video image of the user's operation needs to be captured on the second computer and sent to the first computer, so that the desktop display images of the two computers are synchronized .

[0053] Step S101, when the collected video image is a key frame, perform video compression on the collected video image. In the specific i...

Abstract

The embodiment of the invention discloses a method and a device for compressing and decompressing video data and a mobile terminal, wherein the compressing method comprises the following steps of: collecting a video image; when the collected video image is a key frame, performing video compression of the collected video image; when the collected video image is not a key frame, performing difference operation of the collected video image and a video image collected previously; obtaining a difference image; and performing video compression of the difference image. According to the embodiment of the invention, with the premise of ensuring high compression rate of data compression, intact data can be ensured.

Description

technical field [0001] The invention relates to the field of video compression, in particular to a video data compression and decompression method, device and mobile terminal. Background technique [0002] At present, it is often necessary to compress the video before transmitting the compressed video data over the network, so as to reduce network transmission volume and save network bandwidth. However, conventional compression and decompression methods (such as (MPEG, Moving Picture Experts Group), (AVI, Audio Video Interleaved), etc.) are currently used to compress video data. Compression damage, cannot guarantee that the data will be compressed and decompressed intact. Contents of the invention [0003] The problem to be solved by the present invention is to provide a video data compression method, a video data decompression method, a video data compression device, a video data decompression device, and a mobile terminal. The invention can guarantee the integrity of t...
