Embodiment Construction

[0039] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0040] The video data pixel matrix conversion method designed and realized by the present invention can effectively compress the data at the video sending end, and at the same time perform lossy restoration of the data at the receiving end, which reduces the occupancy rate of video data to the network transmission bandwidth and saves network transmission resources. figure 1 Be the method flowchart of the present invention, below in conjunction with figure 2 and image 3 The specific implementation method of the present invention is introduced in detail.

[0041] [Step 1] Build an image frame model;

[0042]The image frame is composed of pixels distributed on the entire image frame, and the image frame at a certain moment is abstractly modeled, assuming that the resolution of the video is m×n, where m and n represent the number of rows of pixels in t...

Abstract

The invention provides a video data transmission method based on high-dimensional matrix transformation, and the method comprises the steps: building an image frame model, enabling a video data transmitting end to carry out the compression transformation of a pixel matrix of transmitted video data in the image frame model, and then carrying out the reduction transformation of the pixel matrix of received video data in the image frame model. According to the invention, the occupancy rate of the video service on the transmission bandwidth is greatly reduced; through a video data lossy compression algorithm in the invention, the actual transmitted video service volume is reduced to one fourth of the original video service volume, the data capacity of the original video is greatly compressed,the occupancy rate of the video data on the network transmission bandwidth is reduced, and the network transmission resources are saved.

Description

technical field [0001] The present invention relates to the technical field of data link data transmission, especially under the requirement of transmitting huge video data in a tactical data link system with limited bandwidth resources, in order to solve the problem of video data compression and restoration, an effective and feasible video data transfer method. Background technique [0002] The data link is a real-time information processing, exchange and distribution system linking the command center and each participating unit on the digital battlefield. It is a message format and communication protocol according to regulations, and is used for real-time data transmission of various tactical information. and processing system. As an important tactical information, video information will play an increasingly important role in the future battlefield. The existing data link network has limited transmission bandwidth, and in addition to video information, a large amount of ...
