摘要
The present invention discloses a method and a device for fast pushing a unicast stream in a Fast Channel Change (FCC), and relates to the field of Internet Protocol Television (IPTV). A server obtains a multicast join delay of a terminal, determines a minimum value of a data amount between a starting position of a fast unicast stream and a latest packet position according to the multicast join delay of the terminal, a decoding rate, a unicast push rate, and a lowest buffer data amount required for decoding, judges whether a latest I frame completely arrives according to a packet buffer state; and fast pushes the unicast stream starting from the latest I frame if the latest I frame completely arrives, and an arrived data amount starting from the latest I frame is greater than or equal to the minimum value.
