Abstract

A teletext information displaying method and the apparatus therefor for a wide-screen television receiver by which both the list and the contents of received teletext pages are displayed on a 16×9 A.R. screen, so that a user can easily find desired teletext information without the necessity of individually entering page data for page search. According to the present method and apparatus, teletext page data being received is stored in a first memory, and the list of the stored pages is created and stored in a second memory. The page list and the contents thereof are selectively displayed on a 4×3 A.R. region and a remainder region of the 16×9 A.R. screen. Also, when the channel is selected, information on the teletext pages having been received and stored and the teletext type are displayed for a predetermined time with a television picture, thereby providing convenience in use.

Claims

1. A teletext information displaying method for a wide-screen television receiver, comprising the steps of:

automatically checking whether a corresponding teletext page number is received by the receiver when the page number is selectively inputted by a user;

automatically storing the page number in a first memory location when the page number is received;

automatically checking whether an information page corresponding to the page number is received or not, automatically decoding the information page if the information page is received, and automatically forming and storing a display page in a second memory location, said display page corresponding to said information page after decoding; and

automatically displaying the page number on a 4×

3 aspect ration (A.R.) region of a 16×

9 A.R. screen, and automatically displaying the display page on a remainder region of the 16×

9 A.R. screen.

3. The teletext information displaying method of claim 1, wherein said step of checking whether a corresponding teletext page number is received when the page number is inputted by a user further comprises the steps of:

clearing a counter in a teletext information processing section;

incrementing said counter up to a maximum value;

determining whether said corresponding teletext page is received after incrementing said counter; and

storing a message indicating that no corresponding teletext page was received if said counter is incremented up to said maximum value without receiving said page.

2. A teletext information displaying method for a wide-screen television receiver, comprising the steps of:

discriminating whether teletext pages are received if a page search is demanded by a user,

automatically displaying a "no teletext" message if the teletext pages are not received,

automatically receiving and storing the teletext pages if the teletext pages are received,

automatically creating a page list of received page numbers and displaying the page list on a 4×

3 aspect ratio (A.R.) region of a 16×

9 A.R. screen and automatically displaying a first teletext page listed in the page list on a remainder region of the 16×

9 A.R. screen;

displaying on the remainder region of the 16×

9 A.R. screen a particular page selected by movement of a cursor on the list at each display step;

displaying the particular page selected on the full 16×

9 A.R. screen if enlargement of the page is demanded by the user at each display step; and

stopping the page search if page search finish data is inputted at each display step, and switching over to a television mode for displaying an input video signal.

4. A teletext information displaying method for a wide-screen television receiver, comprising the steps of:

discriminating whether teletext pages are received if a page search is demanded by a user,

automatically receiving and storing the teletext pages if the teletext pages are received,

automatically creating a page list of received page numbers and displaying the page list on a 4×

3 aspect ratio (A.R.) region of a 16×

9 A.R. screen and displaying a first teletext page listed in the page list on a remainder region of the 16×

9 A.R. screen; and

displaying on the remainder region of the 16×

9 A.R. screen a particular page selected by movement of a cursor on the list at each display step.

5. The teletext information displaying method of claim 4, further comprising the steps of:

automatically displaying a "no teletext" message if the teletext pages are not received, at the discriminating step;

displaying the particular page selected on the full 16×

9 A.R. screen if enlargement of the page is demanded by the user at each display step; and

stopping the page search if page search finish data is inputted at each display step, and switching over to a television mode for displaying an input video signal.

6. A teletext information displaying method for a wide-screen television receiver, comprising the steps of:

discriminating whether teletext pages are received if a page search is demanded by a user;

automatically receiving and storing the teletext pages if the teletext pages are received;

automatically creating a page list of received page numbers and displaying the page list on a 4×

9 aspect ratio (A.R.) region of a 16×

9 A.R. screen, and displaying a first teletext page listed in the page list on a remainder region of the 16×

9 A.R. screen; and

displaying on the remainder of the 16×

9 A.R. screen a particular page selected by movement of a cursor on the list at each display step.
