Patent

CA 2625756

Systems and methods are disclosed for inserting programs into broadcasted primary programs by a conditional access (CA) module that is inserted into a host device, such as a digital-ready television. The CA module utilizes primary and secondary program map tables and/or primary and secondary packet identifiers. A splicer splices the secondary packet identifiers, which is associated with a secondary program, into the primary packet identifiers, which is associated with a program, such as a broadcasted program. Additionally, the CA module may contain memory that is capable of storing the secondary program's packet identifiers and/or program map table that can be used for insertion into the primary program.

L'invention concerne des systèmes et procédés permettant d'insérer des programmes dans des programmes principaux diffusés par un module d'accès conditionnel (CA) qui est inséré dans un dispositif hôte, par exemple une télévision prête pour le numérique. Le module CA utilise des tables d'index de programmes principales et secondaires et/ou des identificateurs de paquets principaux et secondaires. Une colleuse colle les identificateurs de paquets secondaires, qui sont associés à un programme secondaire, aux identificateurs de paquets principaux, qui sont associés à un programme, par exemple un programme diffusé. En outre, le module CA peut contenir une mémoire pouvant stocker les identificateurs de paquets du programme secondaire et/ou la table d'index de programme pouvant servir à l'insertion dans le programme principal.
