A method and apparatus for encoding data into a digital program stream includes receiving a digital program stream having a pre-allocated data channel, where the pre-allocated data channel has a pre-defined bandwidth. In one embodiment, metadata may be received and an unused portion of the pre-defined bandwidth of the pre-allocated channel may be determined. In another embodiment, metadata may be encoded into the unused portion of the pre- defined bandwidth.

L'invention concerne un procédé et un appareil de codage de données dans un flux de programme numérique qui comprend la réception d'un flux de programme numérique ayant un canal de données préalloué, le canal de données préalloué ayant une bande passante prédéfinie. Dans un mode de réalisation, des métadonnées peuvent être reçues et une partie non utilisée de la bande passante prédéfinie du canal préalloué peut être déterminée. Dans un autre mode de réalisation, des métadonnées peuvent être codées dans la partie inutilisée de la bande passante prédéfinie.
