Abstract: A television program broadcasting arrangement includes a television program broadcasting network, at least one broadcast system, a television program receiver, a data network, a presence server, and a presence client. The at least one broadcast system is configured to broadcast television programs via a plurality of network channels. The television program receiver is configured to receive television programs that are broadcast via the television program broadcasting network. The presence server is configured to provide the data network with television channel presence information associated with the network channels. The presence client is configured to receive the presence information, provided by the presence server, via the data network. The presence client and television receiver are associated with one another such that the television receiver is controllable via the presence client.

Abstract: A system is described for distributing TV signals to an end-terminal. The system comprises at least one central broadcast station, a channel manager and one or more end-terminals connected to the channel manager. The broadcast station is adapted to transmit at least one TV channel signal, comprising an audio signal and a video signal and one or more service signals to the channel manager. Further, the channel manager is adapted to receive the TV channel signal, to extract the audio, video and service signals from the TV channel signal, to transform the signals into packetized elementary streams and to transmit a packetized data transport stream to the channel manager. The transport stream comprises a TV channel stream, comprising elementary audio and video streams, and a services channel stream, comprising one or more elementary service streams and the one or more end-terminals are adapted to select between the TV channel stream and the services channel stream.

Abstract: System for personalized information distribution (PID) from an information source server (1) to several user terminals (2) via an information distribution network (3) comprising several active nodes (4), forming a PID-tree (5). The active nodes comprise distribution control means (6) setting the information distribution process in the relevant active node in accordance with local distribution parameters (parm). The distribution parameters are manageable via said network by distribution control codes (dcc) originated by said user terminals or by other active nodes in the PID-tree.
