  • the reception of new messages can be impossible because the connection with, for example, the cable is interrupted. If no messages have been received this is brought to the attention of the user by the means. This can be effected, for example, in that a message is added to the second video signal to indicate that no new messages have been received. The user can then take action to restore the reception of new messages.
  • the control means may further include means for the management of the messages stored in the storage medium 8.
  • Criteria whether a stored message may be replaced are, for example, the date at which the message has been stored or the number of times that a message has been read by the second read means 10. These criteria may also depend on the interests of the user, so that messages which are of less interest to the user are overwritten with message which are of more interest to the user. In this way, the messages displayed for the user are better in keeping with his interest profile.
