摘要
The invention concerns a method and equipment for allocating to a television programme already conditionally accessed a complementary conditional access. The method consists in the following steps: receiving a message by means (102A, 112) provided with access rights to a programme, restoring the control words, constituting complementary access control and access entitlement messages corresponding to a complementary access system and re-emitting the unmodified initial programme with, in addition, the complementary messages linked to the complementary access control. The invention is applicable in the field of television.
