摘要： A method and an apparatus of multi-view coding and decoding are provided. In the process of encoding multi-view video images, a frame number and view identifier information of the image that uses auxiliary reference information are written into a code stream, and sent to the decoder. The decoder obtains the frame number and the view identifier information of the image that uses the auxiliary reference information, and determines the auxiliary reference information applied to a specified image according to the frame number and the view identifier information. Errors of the image may be concealed according to the auxiliary reference information.

摘要： 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.
