Problems solved by technology

However, due to the inherent characteristics of wireless channels, such as low reliability, easy packet loss, and bandwidth that may change at any time, the development and promotion of mobile audio and video services are limited to a certain extent.
At the same time, the heterogeneity of mobile terminals also increases the difficulty of implementing mobile audio and video
At present, the two main problems that seriously affect the user experience are "delay" and "poor quality". How to ensure the service quality of mobile audio and video services has become a research hotspot in the field of multimedia and mobile communication
