    摘要: Methods and devices for encoding/decoding a video bitstream are provided. The decoding method includes: a slice bitstream is received, wherein the slice bitstream carries parameter set indication information for indicating a camera parameter set; the camera parameters are acquired from the camera parameter set indicated by the parameter set indication information; and the slice bitstream is decoded according to the acquired camera parameters. By the present invention, the technical problem of lower encoding/decoding efficiency caused by the fact that encoding/decoding can only be normally implemented by carrying the camera parameters in the slice bitstream in the conventional art is solved, and the technical effect of improving the encoding/decoding efficiency is achieved.

    摘要: Provided are a method and device for decoding and encoding supplemental auxiliary information of a three-dimensional video sequence. The method includes: obtaining supplemental auxiliary information for constructing a stereo-pair from a three-dimensional video sequence bitstream, the supplemental auxiliary information being used for indicating that the stereo-pair is constructed from a reconstructed three-dimensional video sequence, and the reconstructed three-dimensional video sequence being obtained by decoding the three-dimensional video sequence bitstream. The present invention solves the technical problem in the prior art that degraded displaying quality of a constructed stereo-pair appears because of the lack of supplemental auxiliary information in a three-dimensional video sequence bitstream, and achieves the technical effect of improving the display quality of a constructed stereoscopic video.
