| Système d'accès conditionnel téléchargeable pour les réseaux unidirectionnels – Architecture du système |
La Recommandation UIT-T J.1027 spécifie une architecture de système concernant le système d'accès conditionnel téléchargeable (DCAS) unidirectionnel pour les réseaux unidirectionnels. Un système DCAS unidirectionnel protège les contenus/services de radiodiffusion et permet de contrôler l'habilitation des consommateurs, comme les systèmes d'accès conditionnel classiques, et permettent aux terminaux tels que les boîtiers-décodeurs (STB) de s'adapter à un nouveau système d'accès conditionnel en téléchargeant et en installant le client de ce nouveau système sans changer le matériel. En particulier, un système DCAS unidirectionnel peut fonctionner pleinement dans les réseaux unidirectionnels de télévision par câble et dans d'autres réseaux unidirectionnels tels que les réseaux de télévision par satellite. |
