Abstract

The present invention relates to a data information display method of a data broadcasting receiver and an apparatus thereof, in particular to a data information display method of a data broadcasting receiver and an apparatus thereof which is capable of selecting a simple data information picture or a data information picture or a general television picture according to a viewer select in a digital data broadcasting, and knowing overall content of the present receiving data information without switching the present audition television picture into the data information picture when the viewer selects the simple data information picture. The present invention comprises a parsing unit for analyzing the data information, a summary information extracting unit as an additional module of the parsing unit for detecting the abridged data content of the data information, a formatting unit for formatting the data information outputted from the parsing unit in order to display it, a displaying unit for displaying and transmitting the data information formatted on the formatting unit to a screen, and a user interface for transmitting and receiving signals with the parsing unit according to the input of the viewer. Accordingly, the viewer can watch the television picture faithfully and at the same time can use the data appropriately also.

Claims

1. A data information display method for a data broadcasting receiver, comprising:

tuning signals received through an antenna and detecting whether or not data information is received among the signals tuned by a tuner;

displaying a general television picture when the data information is not detected;

parsing a HTML document among the data information when the data information is detected;

providing both first and second selectors, the first selector for displaying a summary version of the HTML document of the data information, the second selector for displaying a detailed version of the HTML document;

extracting summary information from the parsed HTML document; and

displaying simple data information on the screen as a simple data information picture by using the extracted summary information in response to a selection of the first selector, the simple data information including size information identifying a size of a television picture to be displayed with the detailed version of the HTML document,

wherein the simple data information picture is displayed on a present audition television picture as a font having a translucent ground in order to enable a viewer to view the present audition television picture with the simple data information picture superimposed over the audition television picture.

2. The data information display method for the data broadcasting receiver according to claim 1, wherein the summary information extracting process further comprises:

extracting title information of each HTML page of the HTML document; and

extracting title information of linked documents for each HTML page by extracting linked data.

3. The data information display method for the data broadcasting receiver according to claim 1, wherein the simple data information displaying step comprises:

displaying the summary version of the HTML document at a viewer'"'"'s requested time after storing the simple data information on a storing unit according to the viewer selection.

4. The data information display method for the data broadcasting receiver according to claim 2, wherein the extracting step for extracting the title information of each HTML page extracts a tag displayed as a <

title>

in each HTML document using a PE (presentation engine) unit.

5. The data information display method for the data broadcasting receiver according to claim 2, wherein the summary information extracting step further includes extracting the size information of the television picture to be displayed from the data information.

6. The data information display method for the data broadcasting receiver according to claim 2, wherein the extracting step for extracting the title information of the linked documents is performed while the HTML document is parsed.

7. The data information display method according to claim 1, wherein the step of displaying the simple data information includes displaying the summary version of the HTML document when the first selector is selected, and displaying the size information identifying a picture size of a general television picture to be displayed with the detailed version of the HTML document.
