Because of the proliferation of video streaming services, an increasing number of individuals have recently joined distribution networks. Streaming video solutions that follow the conventional concept of relying on the server and clients use a significant amount of the server’s available bandwidth. Many Peer-to-Peer (P2P) streaming techniques have been emerged in recent years in response to the growing demand for live and on-demand video streaming services delivered via wireless networks at reduced costs to the hosting providers. P2P computing is an innovative method for developing programmes that run over-dispersed networks. Traditional error correction techniques continue to be poorly adapted for video transmission, despite the growth of potentially problematic channels for video transmission, such as wireless and IP. The combination of these two reasons served as the fundamental influence for developing a new set of approaches to solve video transmission errors. These methods are known as error concealment. In this study, we present a multiple description coding technique that we call Flexible Spatial-Temporal (FST). It is more error-resistant than previous approaches, particularly when it comes to the loss of frames due to unrelated channels, which is one of the most common types of error that can occur. It offers an approach that blends geographical concealment with temporal concealment at the receiver so that the missing frames may be hidden more effectively. According to the results of the trials, the solution that was recommended is capable of achieving a decent level of watching performance of video over a P2P based wireless network.
