CA 2655493

Systems and method for encapsulating an MPEG program stream in an MPEG transport stream are disclosed. In one embodiment comprises the steps of: receiving a plurality of elementary streams, each of the elementary streams divided into access units; and generating an MPEG transport stream which encapsulates an MPEG program stream by combining, in order, a program stream pack header, a packetized elementary stream (PES) packet produced from one of the elementary streams, and a PES padding stream packet. so that total size of the pack header, PES packet and PES padding stream packet is equal to a size derived from a predefined pack size.

L'invention concerne des systèmes et un procédé pour encapsuler un flux de programme MPEG dans un flux de transport MPEG. Un mode de réalisation de l'invention comprend les étapes consistant à : recevoir une pluralité de flux élémentaires, chacun étant divisé en unités d'accès; et générer un flux de transport MPEG qui encapsule un flux de programme MPEG en combinant, dans l'ordre, un en-tête de paquet de flux de programme, un paquet de flux élémentaire en paquet (PES) produit à partir d'un des flux élémentaires, et un paquet de flux de remplissage PES, de sorte que la taille totale de l'en-tête de paquet, du paquet PES et du paquet de flux de remplissage PES est égale à une taille déduite d'une taille de paquet prédéfinie.
