Title (EN) METHOD AND DEVICE FOR DIRECTLY ACCESSING DATA CONTAINED IN A FLOW
(FR) PROCEDE ET DISPOSITIF D'ACCES DIRECT A DES DONNEES CONTENUES DANS UN FLUX.
Abstract:
(EN) The invention concerns a method wherein an encoding device generates a flow (F2) in which a binary data (bi) is associated with each frame (Ti), said binary data representing a change of encoding parameters (PVi) used to encode the encoded data (DDCi) contained in the frame associated with said binary data.
(FR) Ce dispositif de codage génère un flux (F2) dans lequel une donnée binaire (bi) est associée à chaque trame (Ti), cette donnée binaire étant représentative d'un changement des paramètres (PVi) de codage utilisés pour coder des données codées (DDCi) contenues dans la trame associée à cette donnée binaire.
