Technical Field

Background
The following problems exist in the current playing system integrated with the P2P (Peer-to-Peer) kernel: on the one hand, for the user who does not want to start P2P uploading, P2P cannot be performed. On the other hand, the P2P can only be performed in a node playing in real time, whether the interactive data can be performed depends on whether the playing progress of the two playing ends is similar, and if the playing progress is far away, the effective P2P cannot be performed.

In view of the above problems, no effective solution has been proposed at present.
