We investigate the effect on free view synthesis quality by changing the transmission rates between multiview and depth sequences. In the simulations, we employ MVC in parallel to compress the multiview video and depth sequences at different bitrates, and compare the virtual view sequences generated by decoded stream with the original video sequences taken in the same viewpoint. Our results show that multiview depth bitrates has less effect on the view synthesis quality compared with the multiview video bitrates.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"IEICE Technical
