  • Patent number: 9083972
    Abstract: 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.
