Content control via guide data and/or metadata

摘要

Metadata of the type for instance associated with television or video Electronic Programming Guides (EPG) or Interactive Programming Guides (IPG), is transported via a digital delivery network such as the Internet to a video receiving device such as a personal video recorder (PVR). The receiving device extracts the metadata for a purpose such as determining from the metadata programming of control signals. The PVR thereby reads or interprets control signals derived from the metadata provided via the digital delivery network so as to control subsequent video recording.
