    摘要: There are provided selective prediction encoding and decoding methods and selective prediction encoding and decoding devices. The selective prediction encoding device selects and performs one of an AC/DC prediction encoding method and an intra prediction encoding method which corresponds to the smaller of code amount from AC/DC prediction and an amount of AVC intra coding, records information indicating the selected encoding method in a header of a bit stream, and transmits the bit stream to the selective prediction decoding device. The selective prediction decoding device decodes the transmitted bit stream by the use of a decoding process corresponding to the information recorded in the header. Accordingly, it is possible to improve compression ratio and image quality by using the selective prediction encoding and decoding methods.

    摘要: Provided are bitstream encoding/decoding methods and devices. The decoder includes: a condition information extracting unit creating recognition information using syntax tree information indicating a hierarchical structure between syntax elements corresponding to bits of an input bitstream, respectively and rule description information indicating connectivity between the syntax elements; and a decoding unit decoding data contained in the bitstream into moving image data using the recognition information. Accordingly, it is possible to decode bitstreams encoded in a variety of types (syntax, semantics) corresponding to a variety of standards (for example, MPEG-1, MPEG-2, MPEG-4, and MPEG-4 AVC) by the use of the same information recognition method.
