Abstract: In accordance with embodiments, a method of transmitting a video includes inter-view redundancy removing pictures for multiple viewing positions; packing inter-view redundancy removed pictures; and/or encoding the packed pictures and/or signaling information including center view generation information, pre-generation information, view synthesis recommendation information and/or reference view information. In accordance with embodiments, a method of receiving a video includes decoding a bitstream of the video based on viewing position and/or viewport information, unpacking pictures in the decoded bitstream; view regenerating the unpacked pictures; and/or view synthesizing the view regenerated pictures.
