Real Time Broadcasting Method of Sports Events Using Wireless Network Communication Technology

Abstract

With the increase of time, the problem of image quality reduction caused by unbalanced network load will appear in the real-time broadcasting of sports events. A real-time broadcasting method of sports events is designed by using wireless network communication technology. Audio and video decoding and coding are divided into two independent threads working at the same time, which can make the frame rate reach the HD standard and enhance the stability of the encoding and decoding process. The GAN model is used to enhance the rate conversion. In the inter frame mode, integer transformation, quantization, reordering and entropy coding are performed on the residual block to complete the coding of the macroblock, which is stored or transmitted through the NAL layer. Wireless network communication technology is applied to distribute the number of channels in the space of mutual interference and balance the load of relay network. For the viewer, after receiving the streaming media data block, analyze the RTP packet, decode the video data, and then play the video. The test results show that the real-time broadcasting method of sports events using wireless network communication technology can improve PSNR, reduce the distortion of video sequence and ensure the stability of output picture.
