Abstract
The method for processing a multiview video signal according to the present invention acquires motion information generated by predictively coding a picture of a reference point, acquires motion information on a part of a block of the picture from among the motion information generated by predictively coding the picture of a non-reference point, and compresses the motion information acquired for every picture of the reference point and non-reference point and stores the compressed motion information.
Claims12
A method for processing a multiview video signal, comprising:
- acquiring reference view motion information of all blocks included in a reference view picture, wherein the reference view picture is included in a reference view;
- acquiring non-reference view motion information on part of blocks included in a non-reference view picture, wherein the non-reference view picture is included in a non-reference view and the non-reference view picture is coded using the information of reference view;
- and
- compressing the reference view motion information and the non-reference view motion information by predetermined resolution;
- and
- storing the compressed reference view motion information and the compressed non-reference view motion information in a decoded picture buffer unit,
- wherein a number of the all blocks from which the reference view motion information is acquired is larger than a number of the part of blocks from which the non-reference view motion information is acquired,
- wherein each of the reference view picture and the non-reference picture is composed of 8M*8M blocks (M being a natural number),
- wherein the number of the reference view motion information is 8M*8M,
- wherein the acquiring the non-reference view motion information on part of blocks of the non-reference view picture comprises:
- determining 2M*2M blocks for each 4M*4M block in the picture of the non-reference view;
- and
- acquiring the non-reference view motion information on the determined 2M*2M blocks as representative motion information of the 4M*4M blocks,
- wherein the decoded picture buffer allocates a size of the decoded picture buffer in which the compressed reference view motion information is stored to be larger than a size of the decoded picture buffer in which the compressed non-reference view motion information is stored.
