Transmitter, receiver and/or record carrier for use with an information signal including a coded text line having character codes and control codes for controlling display of characters defined by the character codes

A transmitter for producing an information signal for transmission through a transmission medium, the transmitter comprising:

• main data generator means for generating main data;
• sub data generator means for generating sub data including a coded text line having a number of character codes defining characters, and a number of serial control codes intermixed among the character codes for use in controlling display of the characters on a display unit having a predetermined number of character display positions which is less than the number of character codes in the coded text line, which serial control codes include horizontal scrolling control codes for use in causing and/or controlling a horizontal scrolling of the characters on the display unit;
• and
• combining means for combining the main data and the sub data into the information signal.

A receiver, comprising:

• character display means for displaying at least some characters defined by a number of character codes included in a coded text line, said character display means having a predetermined number of character display positions which is less than the number of character codes included in the coded text line;
• means for receiving an information signal having main data and sub data, the sub data including the coded text line, which coded text line also includes a number of serial control codes intermixed among the character codes for use in controlling display of the at least some characters which are to be displayed on said display means;
• and
• display control means for controlling display of the at least some characters which are to be displayed in accordance with the serial control codes, which serial control codes include marking codes for marking a portion of the character codes defining a group of the characters to be displayed on said display means.
