摘要

A method comprises processing multimedia program content, comprising in-band data, at least by generating hash value sequence data associated with one or more time offsets in the in-band data, and generating information specifying one or more events that are to be performed by a multimedia device at the one or more time offsets when displaying the multimedia program content to a user. The method further comprises creating event identification data comprising the hash value sequence data and the information specifying the one or more events, and sending the event identification data to a multimedia device. The invention also comprises a computer readable storage medium and a server.
