DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device and a method therefor, and is suitably applied to, for example, a television receiver capable of receiving teletext.

[0002]

2. Description of the Related Art Conventionally, in teletext, digital data (hereinafter, referred to as text data) of text programs such as news and sports information.
This is called program data) is time-division multiplexed into a vertical blanking interval of a video signal included in an analog television signal, and the obtained broadcast signal is transmitted.

In this case, the program data is generated in units of textual programs, and comprises a header section 1 and a data storage section 2 as shown in FIG.

[0004] The header section 1 stores program management information such as a program number (000 to 999) added in advance to the corresponding character program, and the data storage section 2 stores the character management information. Page data obtained by sequentially encoding screen data generated using characters and graphics for each program page using a hybrid encoding method (an encoding method combining a pattern transmission method and a character code transmission method). Is stored.

By the way, in text broadcasting, sound information such as music (hereinafter referred to as an additional sound) can be broadcast as a text program, and such additional sound data (hereinafter referred to as "additional sound"). This is referred to as additional sound data) is added to the screen data as needed.

[0006] Here, a television receiver capable of receiving such a teletext broadcast receives a broadcast signal of a designated channel from among broadcast signals of a plurality of channels, and obtains the broadcast signal based on the received broadcast signal. By transmitting the video signal to a cathode ray tube (CRT), a television image based on the video signal is displayed on a display screen of the cathode ray tube.

[0007] In this television receiver,
At this time, program data that is time-division multiplexed in the vertical blanking interval of the video signal is extracted and stored in a memory. When a desired character program is selected and designated by a user, the corresponding program is selected from this memory. While reading out the program data, the page data in the program data is sequentially decoded,
The obtained screen data and additional sound data are sent to a cathode ray tube or a speaker.

As a result, a character screen based on the screen data is sequentially displayed on the display screen of the cathode ray tube so as to be turned over, and an additional sound based on the additional sound data is emitted from the speaker, and thus the user desires. It is made possible to watch a text program.

[0009]

As a television receiver having such a configuration, there is a television receiver provided with a cathode ray tube of a wide television system. In this type of television receiver, a character screen and a television image are simultaneously displayed on the display screen of the cathode ray tube, so that the television image can be viewed together with the character screen.

Here, the character screen is the display screen of the cathode ray tube.
It is generated in a predetermined size (hereinafter referred to as a character reference size) such that it is displayed at a predetermined angle of view of approximately 3 to 4 using 92 scanning lines. However, if the character screen is displayed on the display screen of the cathode ray tube at the character standard size,
This display screen (for example, having 525 scanning lines)
Is displayed relatively small, making it difficult to see.

Accordingly, recently, as shown in FIG. 11, a first display area of a size corresponding to the character reference size is provided on the right side of the display screen 3 in the horizontal direction (hereinafter simply referred to as the horizontal direction) in the cathode ray tube. 4 and a second display area 5 having a size larger than the first display area 4 is provided on the left side in the horizontal direction, and the first and second display areas 4 are provided.
And 5, the character screen and the television image are switched and displayed as necessary, so that the character screen is displayed in the first display area 4 at the character reference size, but the second display area 5 is displayed. Inside, the character screen is enlarged and displayed.

In this display screen 3, various operation commands for a text program, such as changing a text program and turning pages of a text screen, can be selectively designated in an empty area near the first display area 4. An operation panel 6 is displayed so that the user can input various operation commands while looking at the display screen 3, thus improving operability.

By the way, in such a configuration of the display screen 3, the operation panel 6 is displayed apart from the first and second display areas 4 and 5, respectively, and the operation panel 6 is displayed in the first and second display areas 4 and 5. Can be switched as necessary, and it is difficult to determine which of the first and second display areas 4 and 5 the operation panel 6 corresponds to, and the usability is poor. There was a case.

For this reason, when the character screen is displayed in the first display area 4, the operation panel 6 is connected above the first display area 4, and the character screen is enlarged. When displayed in the second display area 5, the operation panel 6 is enlarged so as to have a size corresponding to the size of the second display area 5, and is enlarged above the second display area 5. It is considered that usability can be improved by connecting and displaying the character screen and the operation panel 6 in such a manner as to always correspond to each other.

In the program data, as shown in FIG. 12, additional information (hereinafter referred to as a header) for recognizing a character program such as a program name and a program number defined in advance to be represented by 31 characters or less. It is considered that this header information is displayed together with the operation panel 6 above the first and second display areas 4 and 5. Thus, it is considered that the character program being displayed can be easily recognized based on the header information, and the usability can be further improved.

Incidentally, the header information is generated in a predetermined size (hereinafter, referred to as a header reference size) which is displayed on the display screen 3 using 12 scanning lines. Are connected and displayed with this header reference size, and are enlarged and connected in the second display area 5.

If the character screen and the header information are enlarged at a magnification other than an integral multiple in the vertical direction (hereinafter, simply referred to as the vertical direction) and the horizontal direction of the display screen, the calculation by this enlargement processing becomes complicated. The configuration of the circuit that executes this enlargement processing becomes complicated. For this reason, the character screen and the header information are enlarged about twice in the vertical and horizontal directions, respectively, in consideration of the size of the display screen 3 of the cathode ray tube,
This simplifies the calculation of the enlargement processing and simplifies the configuration of the circuit that executes the enlargement processing.

When the character screen is displayed in the second display area 5 and the header information and the operation panel are sequentially connected to the upper side of the second display area 5, the entire vertical width is reduced. The width becomes smaller than a predetermined vertical width (525 lines) on the display screen of the cathode ray tube.

However, since the image may be distorted at the vertical end of the display screen 3, the header information and the operation panel are actually connected sequentially to the second display area 5 on the display screen 3 of the cathode ray tube. The image is displayed within a width slightly shorter than the entire vertical width (hereinafter, referred to as an effective display width). For this reason, when a character screen is displayed in the second display area 5, a part of either the operation panel 6 connected to the second display area 5 or the header information is displayed. Thus, there was a problem that the usability was difficult to improve.

The present invention has been made in consideration of the above points, and has as its object to propose a display device and a method thereof that can improve the usability.

[0021]

According to the present invention, there is provided a display device, comprising: a display device for generating screen data of a character screen and header information enlarged from a reference size based on program data; Means,
A storage unit for storing panel data of an operation panel of a predetermined size corresponding to the size of the character screen in advance; a screen data generated by the screen data generation unit; and a display screen based on the panel data stored in the storage unit. The character screen and the operation panel are displayed so that the character screen and the operation panel are connected along the vertical direction of the display screen, and the operation panel is scrolled along the vertical direction at a predetermined timing for a predetermined period. And a display control means for displaying header information.

As a result, the character screen, the operation panel, and the header information can be displayed in association with each other within the effective display width of the display screen.

Also, in the present invention, in the display method, a first step of generating screen data of a character screen and header information enlarged from a reference size based on program data, a screen data and a size of the character screen Based on the panel data of the operation panel of a predetermined size corresponding to the above, the display screen is displayed so that the character screen and the operation panel are connected along the vertical direction of the display screen, and the operation panel is displayed at a predetermined timing for a predetermined period.
