Abstract

The invention discloses an unmanned aerial vehicle air-ground video transmission method. The method comprises the steps of preprocessing custom data; obtaining an image compression code stream; packaging the preprocessed custom data into a preset field of an image compression code stream to obtain a new image compression code stream; packaging the new image compressed code stream into streaming media video data; transmitting the packaged streaming media video data to a receiving end; analyzing the streaming media video data to obtain an image compressed code stream; analyzing the image compressed code stream to obtain user-defined data in a preset field; decoding the image compressed code stream to obtain an original video image; and processing the original video image to obtain a new video image. According to the method, the custom data is embedded into the video code stream, video decoding is not influenced, and the custom data is completely lossless. According to the method, the purity of the video pictures is reserved, synchronization becomes simple, delay is reduced, and performance consumption is reduced.

Description

technical field [0001] The invention relates to the field of UAV air-to-ground data transmission, in particular to a UAV air-to-ground video transmission method. Background technique [0002] UAV air-to-ground video transmission currently mainly relies on the image transmission data link, and for most data links, they use the technical solution of broadcasting and television, which only supports data transmission that conforms to the video and audio packaging format, such as encapsulating video streams into MPEGTS In the video application of the UAV, what we see on the ground is not only the video, but also such as the status of the aircraft, various data parameters when the aircraft is flying, etc. The previous solution is the video in the air In the processing equipment, these data are drawn on the video screen in the form of subtitles in real time, and then encoded, encapsulated and transmitted. After the video data is received on the ground, it is decoded and played, and...
