Embodiment Construction

[0071] The present invention will be explained in more detail below in conjunction with the accompanying drawings and examples. It should be noted that, but it should be noted that these embodiments are not limitations of the present invention. , methods, or structural equivalent transformations or substitutions all fall within the protection scope of the present invention.

[0072] Such as figure 1 As shown, it is a flow chart of a video image lossless encoding and decoding method of the present invention, and the method includes:

[0073] S1: Split the original video image into two initial sampling images of equal size, wherein the first initial sampling image is obtained by down-sampling the original video image, and the second initial sampling image is generated by using the lost image information of the first initial sampling image initial sampling image;

[0074] S2: Use the hardware encoder to encode and send the two initial sampling images;

[0075] S3: Use the hard...

Abstract

The present invention relates to a video image lossless encoding and decoding method, comprising: S1: splitting the original video image into two initial sampling images of equal size, wherein the first initial sampling image is obtained by down-sampling the original video image, and using The image information lost in the first initial sampling image is used to generate a second initial sampling image; S2: use a hardware encoder to encode and send the two initial sampling images; S3: use a hardware decoder to decode the received encoding result to obtain Two decoded sampled images; S4: Recombine and restore the two decoded sampled images to generate a lossless color space image. The invention also relates to a video image lossless codec system. Through a certain algorithm and structure, the present invention enables the video encoding and decoding process to use hardware codecs and realize lossless color gamut, and furthermore, in the remote graphics transmission protocol, ultra-low-latency transmission can be realized while having lossless color, Features of high frame rate.

Description

technical field [0001] The invention relates to the field of video encoding and decoding, in particular to a video image lossless encoding and decoding method and system. Background technique [0002] Video coding technology has a very wide range of uses in many industries, such as film and television, animation, TV stations, media, etc. Video coding technology can greatly reduce the amount of original video data while maintaining acceptable clarity for human eyes. At the beginning of the development of video coding technology, it was mainly used in the video field in a narrow sense. With the development of cloud computing technology, video coding technology has been widely used in the remote graphics transmission protocol of virtual desktops, which can effectively improve the remote desktop graphics experience. [0003] In the virtual desktop architecture, the remote graphics transfer protocol is very important. With the development of GPU virtualization technology, the r...
