Embodiment Construction

[0022] figure 1 An overview is given of a digital television system in which the receiver according to the invention can be used. As an example, a system is described in which audio / video (A / V) signals are distributed digitally. In principle, the invention can also be used in analog systems. The system will be described as compressing A / V signals using MPEG-2 compression. The system includes an MPEG-2 compressor 10, which is typically located at a broadcast center. A compressor receives a digital signal stream (usually an analog or digital video signal stream). The original signal is supplied by the service provider. The compressor is connected to a multiplexer and scrambler 20 . A multiplexer 20 receives a further plurality of digital signals, aggregates the transport stream and provides a compressed signal to a transmitter 30 in the broadcast center. Signals may be provided by any suitable connection, including telecommunication links. Transmitter 30 sends electromagn...

Abstract

A broadcast receiver 200 includes a receiver / decoder 210 . The receiver 200 receives a broadcast channel selected by a user from a plurality of broadcast channels available in a broadcast network The receiver makes signals broadcast via the selected channel available to the user. User input means 230 enable the user to specify a user interest profile 400 based on at least one category of preference 410, 420, 430 . An installer 220 install of all channels available in the broadcast network only those channels that meets the user interest profile 400.

Description

technical field [0001] The present invention relates to a method of setting a channel in a broadcast receiver and a broadcast receiver. Background technique [0002] US 6252635 discloses a method of setting channels in a broadcast receiver for an analog broadcast system. The network provider sends a list or channel number of all receivable broadcast stations on a tuned frequency. This list is called the channel list. Usually the channel list is transmitted together with at least one broadcast television program, for example as a teletext page transmitted on a loop. When setting up a broadcast receiver, the channel list is obtained by tuning to a channel. The channel list is then decoded and stored in memory (effectively setting all channels on the list) without any further user intervention. Thereafter, all channels can be read via the program number determined by the network provider. It is also possible to automatically set only those channels that are part of a subsc...
