    Abstract: Provided are a method and a device for encoding a video to improve an intra prediction processing speed, and a method and a device for decoding the video. The method for encoding a video performs parallel intra prediction and includes: obtaining, by using pixels of peripheral blocks processed prior to a plurality of adjacent blocks, reference pixels used for intra prediction of each of the plurality of adjacent blocks; performing, by using the obtained reference pixels, intra prediction in parallel for each of the plurality of adjacent blocks; and adding reference pixel syntax information to a bitstream.

    Abstract: An image encoding method includes generating symbols by performing transformation and quantization according to a transformation block, on a block that performs prediction according to a prediction mode; updating a probability index of a current sub block by using a probability index of a previous sub block among sub blocks included in the transformation block; determining a rate according to a bit length of the current sub block by using the probably index; determining a rate of the transformation block by using rates of the sub blocks; determining a distortion by using a difference between an original image and a reconstruction image according to transformation and quantization; and determining a rate-distortion (R-D) cost by using the distortion and the rate.

    Abstract: A processing apparatus has a processor including a first memory. The processor divides a frame in video content into a plurality of coding units (CUs), and encodes the plurality of CUs in a diagonal direction to generate an encoded frame, wherein when a first CU is encoded based on a first encoding type, the processor is further configured to load, from a second memory, a first partial region of a reference frame corresponding to first position information of the first CU to the first memory and encode the first CU based on the first partial region of the reference frame loaded from the second memory, and wherein, when the first CU is encoded based on a second encoding type, the processor is further configured to encode the first CU based on a first reference pixel value corresponding to the first position information of the first CU from the first memory.
