Researching on real-time transmission multimedia image in Network teaching

In the research process of real-time transmission multimedia image in Network teaching, there is a problem of poor visual effects in network teaching, due to the current algorithm for image teaching transmission has not fully consider the human visual system. A method of real-time multimedia image transmission based on improved ROI algorithm in network teaching is proposed. In this method, the network status of the teaching is judged by the feedback of the TCP data packets. ROI image transmission is carried out with the data frame length of the multimedia image transmission in the network teaching. Under the premise of not affecting the quality of the real-time transmission of ROI in the network teaching, wavelet coefficients delayed transmission is proposed with bandwidth savings to complete the real-time transmission of multimedia image. The experimental results show that the real-time transmission of multimedia image transmission method based on the improved ROI algorithm is effective, and the visual effect is good.
