Patent

CA 2484519

Segmentation messages indicative of locations of upcoming events, such as the start and the end of programs and program portions, and/or rights related to the programs and program portions, are used by cable systems and the like to store programs and program portions for later retrieval and transmission to customers on request. Storage, retrieval and management of programming is thereby facilitated. Messages, such as segmentation messages, may indicate a time to an upcoming event and an elapsed time from a prior event. The messages may be placed at equal intervals between events. Methods and systems are disclosed.

On peut utiliser des messages de segmentation pour indiquer l'horaire d'événements futurs tels que le début et la fin de programmes ou de portions de programme, ou les droits y afférents; on recourt à cette fin à des systèmes de câbles ou analogues pour stocker les programmes ou leurs portions en vue de leur extraction ultérieure et de leur transmission sur demande aux clients. On facilite ainsi le stockage, l'extraction et la gestion des programmations. De tels messages peuvent indiquer le moment d'un événement futur ou le temps écoulé d'un événement antérieur. Les messages peuvent être placés à distance égale entre les événements. L'invention porte également sur les procédés et systèmes associés.
