The invention discloses a multi-channel received video transmission method and device. The method comprises the following steps: acquiring a plurality of corresponding data packet sequences respectively obtained by a plurality of receiving ends; judging whether a first data packet correspondingly obtained by the first receiving end is lost or not according to the serial number mark; if no packet loss exists, only outputting the first data packet sequence; if there is packet loss, according to the serial number mark corresponding to the packet loss, obtaining the data packet missing the first data packet sequence from the data packet sequences obtained by other receiving ends, combining the data packet missing the first data packet sequence with the first data packet sequence according to the sequence of the serial number mark to obtain a recombined data packet sequence, and only outputting the recombined data packet sequence. According to the multi-channel receiving video transmission method and device provided by the invention, the total receiving end is started to receive the data of the plurality of receiving ends, the data of the plurality of receiving ends are fused and complemented, and redundancy is removed, so that the problem of lagging caused by uneven signal quality of the receiving ends and repeated switching in the prior art is solved.
Description
technical field [0001] The invention relates to the technical field of wireless video transmission, in particular to a multi-channel receiving video transmission method and device. Background technique [0002] UAV is an unmanned aircraft operated by radio remote control equipment and self-contained program control device. There is no cockpit on board, but equipment such as autopilot and program control device are installed. The personnel on the ground, on the ship, or at the remote control station of the parent aircraft track, locate, remotely control, telemeter and digitally transmit it through radar and other equipment. Under the radio control, it can take off like an ordinary aircraft or be launched into the air with a booster rocket, and it can also be taken into the air by the parent aircraft for flight. When recovering, it can automatically land in the same way as the common aircraft landing process, and can also be recovered by remote control with a parachute or a ...
