Signal processing system

A method of processing broadcast signals, which method includes:

• selecting a signal source from at least two available broadcast signal sources by means of logically arranged preset positions;
• reading in information from a portable information carrier;
• and
• uniquely identifying a signal source by means of a signal source name,
• wherein the information on the portable information carrier includes at least one correspondence relationship between a preset position and a signal source name.

A signal processing apparatus adapted to operate with a signal processing system having a portable information carrier adapted to store at least one correspondence relationship between a preset position and a signal source name, the signal processing apparatus comprising:

• a signal source selection device, having a plurality of logically arranged preset positions, for selecting one broadcast signal source from at least two available broadcast signal sources,
• a control device for controlling the signal processing device and the signal source selection device,
• read means for reading information from the portable information carrier,
• a memory storing, for at least one set of signal sources, at least one correspondence relationship between a preset position and a signal source,
• wherein the memory comprises a first and a second memory section, the first memory section storing at least one correspondence relationship between a signal source and a signal source name which identifies the signal source within a set of signal sources, and the second memory section storing at least one correspondence relationship between a preset position and a signal source name,
• and wherein the read means reads the correspondence relationships from the portable information carrier and stores the read correspondence relationships in the second memory section.

• and wherein the portable information carrier comprises a memory for storing at least one correspondence relationship between a preset position and a signal source name,
• and wherein the read means reads the correspondence relationships from the portable information carrier and stores the read correspondence relationships in the second memory section.
