Summary: | The invention discloses a rapid start-up system for a multicast channel, which comprises a streaming server, a head end and at least one player, wherein, the head end generates or transfers the media data of the channel and sends the data; the player is provided with a buffer area used for playing the media data; the streaming media is provided with a history buffer area and the history buffer area stores a history coding stream; the coding stream sent by the head end is received by and is stored in the history buffer. When the stream server receives the multicast requirement of the player, the stream buffer fills a history coding in the history buffer area into the buffer area of the player in the unicast way. When the player joins in the multicast, the stream server stops sending the unicast; the player receives the multicast stream after joining in the multicast coding stream and splices the multicast coding stream and the unicast coding stream. The invention effectively increases the playing launch speed, |
