Abstract	The emerging MVC+D standard specifies the coding of Multiview Video plus Depth (MVD) data for enabling advanced 3D video applications. MVC+D specifications define the coding of all views of MVD at equal spatial resolution and apply a conventional MVC technique for coding the multiview texture and the depth independently. This paper presents a modified MVC+D coding scheme, where only the base view is coded at the original resolution whereas dependent views are coded at reduced resolution. To enable inter-view prediction, the base view is downsampled within the MVC coding loop to provide a relevant reference for dependent views. At the decoder side, the proposed scheme consists of a post-processing scheme which upsamples of the decoded views to their original resolution. The proposed scheme is compared against the original MVC+D scheme and an average of 4% delta bitrate reduction (dBR) in the coded views and 14.5% of dBR in the synthesized views are reported.
