Abstract: A video encoding/decoding method and apparatus using arbitrary pixels in each sub-block are disclosed. The present disclosure comprises an extractor, a first predictor, a first subtractor, a first transformer, a first quantizer, a first inverse quantizer, a first inverse transformer, a first adder, a second predictor, a second subtractor, a combiner for combining arbitrary residual pixels, a second transformer, a second quantizer, and an encoder whereby arbitrary pixels may be extracted from the respective sub-blocks of a current block and then encoded and decoded into reconstructed arbitrary pixels, which are used to predict and encode the remaining pixels of the respective sub-blocks. According to the disclosed encoding and decoding of a video, an intra prediction of pixels in a block to currently encode or decode is improved in accuracy to increase the video coding efficiency.
