Title (EN) ENCODER AND DECODER
(FR) CODEUR ET DECODEUR
Abstract:
(EN) 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.
(FR) L'invention concerne des procédés et des dispositifs de codage/décodage de flux binaire. Le décodeur comprend une unité d'extraction d'informations de condition utilisant des informations arborescentes de syntaxe qui indiquent une structure hiérarchique entre des éléments de syntaxe correspondant respectivement aux bits d'un flux binaire d'entrée et des informations de description de règle qui indiquent la connectivité entre les éléments de syntaxe; et une unité de décodage décodant les données contenues dans le flux binaire en données d'image de mouvement utilisant des informations de reconnaissance. En conséquence, il est possible de décoder des flux binaires codés selon une variété de types (syntaxe, sémantique) correspondant à une variété de normes (par exemple, MPEG-1, MPEG-2, MPEG-4 et MPEG-4 AVC) par utilisation du même procédé de reconnaissance d'informations.
