Abstract: A method for eliminating the need for custom interfaces between client PC applications and DVB-T receivers. The method uses existing TCP/IP structure to provide details of all currently active connections, and uses a cross reference system on DVB-T SI to identify any filter state changes that are needed. This system obtains filter information by polling the UDP Listener Table or by detecting IGMP status changes. These methods are implemented in receiving terminals, and overcome significant limitations to current methods.

Abstract: A digital video broadcasting network allows a group of end user terminals to dynamically select and receive broadcast content by transmitting program identifiers for a plurality of broadcasting content providers through program specific information (PSI/SI) layer signalling over multiple transport streams.
