Embodiment Construction

[0051] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0052] For the image frames generated by screen sharing screenshots, the images of adjacent frames have a high similarity. The present invention utilizes the similarity principle of adjacent frame images of processed desktop screenshot images to repair image frames missing part of the image data due to loss of data messages, so as to achieve the purpose of improving screen sharing fluency.

[0053] The method that adopts screenshot image of the present invention to realize local area network screen sharing comprises the following steps:

[0054] S1. The image frame generated by the screen capture is divided into blocks, that is, for a picture, the present invention divides it into n regional sub-images, please refer...

Abstract

The invention discloses a method for realizing screen sharing in a local area network by using screenshot images, including but not limited to the following steps: S1, block-processing and caching the image frames generated by the screenshots; After m frames, send; S3, after the screenshot image frame is generated, perform a one-to-one comparison with the original image frame to generate the same area association mapping list information; S4, divide the data stream generated after encoding and compressing the area sub-image Segment, pack into a data message, and send it; pack the information of the same area association mapping list into a control message and send it out; S5. After the screen sharing client receives the data message, it assembles the subpackaged data in turn to form a sub-image of the area, Then assemble into a complete frame image; cache the regional sub-images of the frame image, and also cache the regional sub-image queue of m frames and the frame image queue of m frames; receive and save the same area association mapping list information of the frame image in the control message .

Description

technical field [0001] The invention relates to the technical field of computer screen sharing, in particular to a frame loss optimization method of a local area network screen sharing scheme realized by a frame-by-frame transmission method of screenshot images. Background technique [0002] The simplest and most effective way to implement screen sharing in the LAN is to establish a server through the sharing initiator; the server grabs the screen image, encodes the image in JPG format, then compresses the image, and finally divides the screen image data into multiple data packets through multicast After receiving the data message, the shared client is responsible for reparsing the data message and assembling it into a screenshot image, and then displaying it. In order to reduce the bandwidth load, data packets are usually transmitted in multicast mode. This method is the implementation method in many papers; refer to "Journal of Chengdu Institute of Information Engineering...
