The MVC standard

as an extension of H.264 standard

provides a standardized codec reference for 3D videos. Real time encoding and keeping compatible with H.264 are key problems for deploying MVC in 3D applications. In this paper

a transformation mechanism is proposed based on topological sort

which maps the 2D prediction structure of MVC to 1D reference sequence of H.264

and then uses the basic coding technologies of H.264 to get MVC bit stream with syntax reconstruction. The experiment results show the proposed method could achieve real time performance for MVC-H.264 transcoding and are compatible with existing H.264 codec. The proposed method gives transformation mechanism of bit streams between MVC and H.264

which need no special designed SOC.
