Abstract: The present invention relates to a method and apparatus for encoding and decoding video information. The video information encoding method according to the present invention comprises: a step of performing a prediction on a current block; and a step of entropy-encoding the predicted information and transmitting the encoded information. The step of performing a prediction comprises: a step of acquiring motion information on a neighboring block from the neighboring block of the current block; and a step of determining motion information on the current block on the basis of the acquired motion information. The transmitting step also involves transmitting information required for the prediction of the current block. According to the present invention, the complexity of video compression and the quantity of transmitted information may be reduced.

Abstract: Provided are a method and an apparatus for enoding/decoding a multi-view video using LDI. Specifically, provided are a method and an apparatus for enoding/decoding a multi-view video using LDI, which uses a linear decorrelation process to improve compression efficiency. The LDI encoding method according to present invention includes: (i) generating the LDI including multiple layers by using color and depth information of each viewpoint image of the multi-view video; (ii) performing linear decorrelation in each layer of the LDI; (iii) performing data aggregation in each linearly-decorrelated layer of the LDI; and (iv) encoding the aggregated data in each layer of the LDI to generate an encoded LDI bit stream.
