Receiver for television signals

摘要

A receiver receives television signals in a plurality of channels. Each signal defines a television programme and at least a signal in one of the channels comprises compressed data defining broadcast events in the channels. The receiver produces output signals defining an image of events in the programme schedule for display on a television screen. The receiver receives data defining a dictionary representing text portions, decodes the programme scheduling data to identify text portions in the dictionary, and constructs the image of events from the identified text portions. A signal in each channel comprises a bouquet identity and a sub-bouquet identity for the channel. The receiver stores a reference bouquet identity and one or more reference sub-bouquet identities, compares the bouquet identity and sub-bouquet identity for a channel in a received signal with the reference bouquet and sub-bouquet identities and outputs the received television signal for display of the programme or other services defined thereby depending on the comparison.
