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.

摘要： Provided herein is a method for detecting landing quality of an aircraft. Method steps include using an aircraft data system to determine whether a vertical speed rate is greater than a first preset value when the aircraft lands; determine whether a vertical acceleration is greater than a second preset value if the vertical speed rate is not greater than the first preset value when the aircraft lands; collect landing data; generate a landing message based on the collected landing data; store or transmit the landing message; and determine the landing quality based on the landing data in the landing message.
