<p>Disclosed are a 3D video code transmission method and device. The method comprises: for each frame group of a first video stream captured by a 3D video source, performing intra-frame coding on a first frame, and performing P frame coding on subsequent frames, to obtain a first video code stream; for each frame group of a second video stream captured by the 3D video source, performing motion estimation on corresponding first and second video stream frames to obtain motion vectors and residual images of the frames, performing P frame coding on the residual image of the first frame, performing B frame coding on the residual image of each subsequent frame, and saving the motion vector of each coded frame in the frame to obtain a second video code stream; encapsulating the first and second video code streams into a same multiplexing subframe of a multimedia broadcasting channel frame, storing a video stream number of the second video code stream in a reserved bit of extended information of the first video code stream, and broadcasting the channel frame. The present invention provides a 3D video service through a multimedia broadcasting channel.</p> |
