Document Type and Number:
WIPO Patent Application WO/2020/036384
Kind Code:
A1
Abstract:
the present invention provides an apparatus for transmitting a video, a method for transmitting a video, an apparatus for receiving a video, and a method for receiving a video. preferably, an apparatus for transmitting a video according to embidements of the present invention comprises an inter-view redundancy remover configured to remove redundant information of pictures for viewing positions; wherein redundant pixel information between the pictures in adjacent viewing positions is removed, a packing unit configured to pack the pictures and generate packding information; and an encoder configured to encode the pictures. preferably, the apparatus further comprises wherin the apparatus further performs multi-view packing the pictures into a packed picture and each view for the picture includes different types of a texture and a depth map, and wherein a residual of texture and a depth map are generated for a subsidiary view based on redundancy between each view. preferably, the apparatus further generates signaling information for the inter-view redundancy remover, the packing unit or the multi-view packing. preferably, an apparatus for receiving a video according to embidiments of the present invention comprises a decoder configured to decode a video including a picture and signaling information; an un-packer configured to un-pack the picture in the decoded video; a selector configured to select a picture for a viewing position and a viewport based on the signaling information; a block processor configured to perform: patch filling of the pictures based on in the signaling information, a first disparity compensation of the picture based on the signaling information, and a second disparity compensation of the picture based on the signaling information; a merger configured to merge a full picture based on the patch filled picture and the disparity compensated picture; a block boundary processor configured to reduce blocking information for the the block processor; and a renderer configured to render a picture of a viewport,
