    • Methods and devices of intra prediction encoding and decoding are described, so that the encoding performance of intra coding is better. A prediction encoding is performed on the same frame by using at least two intra prediction encoding modes, and information indicating the intra prediction encoding mode of each block is written into the encoded result, so as to encode different blocks by using the most appropriate modes. By using at least two intra prediction encoding modes, relevant indication information is written into the encoded result, so as to correctly perform the decoding. During decoding, the information of intra prediction encoding mode of each block of the same frame is firstly read, and then the block is decoded by using this mode. Each block is organized in a form of hierarchical tree, so as to obtain the optimal performance, and reduce the amount of the information indicating the intra prediction encoding mode of each block in the encoded result.
