摘要： The present invention relates to a method and an apparatus for encoding/decoding a video using a split layer. The video encoding/decoding method generates an encoded image data by encoding a current block partitioned into a plurality of subblocks, generates an encoded partition information data by encoding partition information of the current block, generates a bitstream including the encoded image data and the encoded partition information data, and then reconstructs the video image from the generated bitstream. According to the present disclosure, when encoding a high resolution video with variable sized blocks, various block shapes may be used for the encoding, and efficient encoding and decoding of the block partition information can improve the compression efficiency.

摘要： An inter-prediction method and a video encoding/decoding method using the inter-prediction method are disclosed. The video encoding method using inter-prediction includes: encoding a first picture that serves as a reference for random access; inter-prediction encoding a block included in a second picture, which is displayed before the first picture, by using a plurality of reference pictures; generating reference picture information representing whether a past picture, which is displayed before the second picture, is used as a reference picture for encoding the second picture; and transmitting the encoded first and second pictures and the reference picture information.
