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. |
