[0024] Reference figure 1 , The existing DIBR-based 3D playback system includes two parts: transmitting and receiving. The depth map data stream D 0 Perform deep preprocessing to get D 1 , Using H.264 / AVC and other BDCT-based encoders to the depth map data stream D 1 And reference graph data flow I 0 Perform encoding, send the encoded data into the transmission channel, and reach the receiving end through the transmission channel, and use the corresponding decoder to decode the compressed data to obtain the reference compressed image I'and the depth compressed image D', and the reference compressed image I'and depth The compressed image D'removes the compression effect, and obtains the reference image I” and the depth image D” after the compression effect is eliminated, and then uses the depth image rendering DIBR technology to render the reference image I” and the depth image D” after the compression effect is eliminated as 3D images and displayed in 3D TV, the method of the pr...
