    摘要: The present disclosure provides a method and apparatus for intra prediction encoding/decoding. The method includes: selecting an intra prediction mode of each block to be encoded; encoding a residual block generated through an intra prediction of the block according to the selected intra prediction mode to generate a coefficient bit; encoding a mode identifier for indicating the intra prediction mode according to the predetermined mode determination method to generate a mode bit; generating a bitstream including a mode bit field including a mode bit for one or more blocks and a coefficient bit field including a coefficient bit for the block; and including a mode bit field pointer for identifying the mode bit field in the bitstream. The present disclosure simplifies the process of selecting a prediction mode in a video compression to improve a compression speed and decreases a size of compressed data to improve the compression efficiency.

    摘要: The present disclosure relates to a method and apparatus for encoding/decoding a motion vector and a method and apparatus for encoding/decoding video using same. The motion vector encoding method includes selecting a predicted motion vector candidate set including one or more predicted motion vector candidates for a block; determining one or more search ranges for predicted motion vector candidate set; selecting one predicted motion vector candidate among one or more predicted motion vector candidates as predicted motion vector for each search point with respect to each search point within search range by first determination criterion prearranged with video decoding apparatus; selecting one predicted motion vector among the predicted motion vectors for each search point by a second determination criterion not prearranged with the video decoding apparatus, and determining predicted motion vector, differential motion vector, and current motion vector; and generating and encoding the differential motion vector as motion information.
