Abstract:
A digital television receiver for receiving a plurality of digital transport streams, comprising:a) tuning means for selecting a selected signal from the digital transport streams in response to control signals; b) first signal processing means for extracting and processing a first type of information, comprising video and audio information, from the selected signal, wherein during a coupled state of the receiver, an input of the first signal processing means is effectively coupled to an output of the tuning means, and during a decoupled state of the receiver, the input of the first signal processing means is effectively decoupled from the output of the tuning means; c) second signal processing means for extracting and processing a second type of additional information from the selected signal; and d) controlling means which generate the control signals for controlling the tuning means when the receiver is in the decoupled state, said control signals being chosen such that the tuning means successively scans the digital transport streams, without user instruction, and selects a respective signal from at least a number of the digital transport streams.
