US Patent 12107697 Media stream sending method and apparatus, and device

A media stream sending method provides a live media stream for a client that enters a live broadcast room. A proxy server receives, from a first client, a first live broadcast room request message for requesting to enter the live broadcast room; the proxy server determines a role of the first client based on the first live broadcast room request message; and if the role of the first client is a slave user, the proxy server sends a first live media stream cached in the proxy server to the first client, where the first live media stream is a media stream that is sent by a media server to a second client through the proxy server, and a role of the second client is a master user.
