[0001] This application is a Continuation of co-pending application Ser. No. 09/709,554, filed on Nov. 13, 2000, which claims priority of Korean Application No. 1999-50281 filed on Nov. 12, 1999. The entire contents of each of these applications are hereby incorporated by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a data information display method of a data broadcasting receiver and an apparatus thereof, and in particular to a data information display method of a data broadcasting receiver and an apparatus thereof which are capable of displaying data information corresponding to the present audition television picture as a simple data information picture without changing the size of the present audition television picture. [0004] 2. Description of the Prior Art [0005] Generally, in a digital data broadcasting, additional data information is transmitted from a transmitter to a receiver with an A/V (Audio/Visual) stream for a television by using digital signals. [0006] In the digital data broadcasting, the transmitter compacts separately the video and audio, encodes it, multiplexes it, and transmits the data stream to the receiver. Then the receiver receives the data stream, corrects all errors, decodes it, and demultiplexes it into the original video and audio. [0007] In order to watch the digital-data broadcasting, an additional data processing S/W program for a digital broadcasting (hereinafter, it is referred to as a data browser) is required for the receiver in order to process the A/V stream and data and to support collectively various kinds of user support services, and the format and function of the data browser is similar to the format and function of an internet web browser. [0008] The internet web browser is a S/W program based on the internet. It comprises a plurality of internet protocols, a HTML (Hyper Text Markup Language) document, a CSS (Cascading Style Sheets) Paser, a Java Script, a JAVA related engine, a formatting function for display, and its own program, and it supports most of e-mail protocols. [0009] In addition, basic functions of the data browser used for the data information display apparatus of the data broadcasting receiver will now be described. [0010] The data browser judges whether or not data is received related to the present audition broadcasting, detects the data when the data is received, informs the data receipt to a viewer by displaying an icon on a screen, and prepares a parsing, formatting, displaying of the received data information. [0011] After that, when the viewer wants to watch the data information receiving at the present and selects a "television and data broadcasting simulcast audition" item by using a remote-controller or an external input device, the data information picture is displayed. When the viewer does not watch the receiving data information, the present audition general television picture is displayed. [0012] FIG. 1 is a block diagram illustrating the conventional data information display apparatus of the data broadcasting receiver. It comprises a tuner 10 for tuning signals received through an antenna, an A/V decoder unit 20 for converting the signal tuned on the tuner 10 into an A/V stream, a screen 30 for displaying the A/V stream outputted from the A/V decoder unit 20, a data receiving unit 40 (listener) for searching whether there is the data information among the signals tuned on the tuner 10, and a PE (Presentation Engine) unit 50 for parsing and formatting the data information detected by the data receiving unit 40 and outputting the data information having the displayable format to the screen 30. [0013] Herein, the PE unit 50 comprises a user interface 57 for receiving an input signal of the viewer, a parsing unit 51 for receiving the user input signal though the user interface 57 and parsing the data information outputted from the data receiving unit 40, a formatting unit 53 for formatting the data information outputted from the parsing unit 51 in order to display, and a display unit 55 for processing the data information formatted on the formatting unit 53 so as to have the displayable format and transmitting it to the screen 30. [0014] Herein, the parsing unit 51 parses the data information outputted from the data receiving unit 40 by using the HTML (Hyper Text Markup Language) document, CSS (Cascading Style Sheet) Paser, Java Script, etc. [0015] The operation of the data information display apparatus of the general data broadcasting receiver having the above-mentioned construction will now be described. [0016] First, the signal received through the antenna is tuned on the tuner 10, the tuned A/V signal is outputted to the A/V decoder unit 20, and the A/V decoder unit 20 converts the tuned signal into the A/V stream. The A/V stream is displayed on the screen 30. [0017] Meanwhile, the data receiving unit 40 detects whether there is data information among the signals tuned on the tuner 10, and stores it when the data information is detected. After that, when the viewer requests the data information output through the user interface 57 while the data receiving unit 40 receives the data information, the parsing unit 51 detects and parses the data information stored on the data receiving unit 40, and outputs the parsed data information. And, the formatting unit 53 formats the data information outputted from the parsing unit 51, and then the display unit 55 receives the data information formatted on the formatting unit 53, processes the formatted data so as to have the displayable format, and transmits it to the screen 30. [0018] FIG. 2 is a flow chart illustrating the general data information display method of the data broadcasting receiver. First, it is detected whether the data information is received among the signals tuned on the tuner 10 through the antenna (ST1). The general television picture is displayed when the data information is not detected (ST6). When the data information is detected, as depicted in FIG. 3A, the icon (for example, `i`) for indicating the presence of data information is displayed on the right upper portion of the screen 30 (ST2). At the same time, in order to output the received data information to the screen 30, the parsing, formatting, displaying are prepared (ST3). When the viewer selects the data information (ST4), in other words, when the viewer selects the "television and data information simulcast audition" icon through the remote-controller or external input device, as depicted in FIG. 3B, the data information is displayed on the screen 30 (ST5). [0019] Meanwhile, when the viewer does not select the "television and data broadcasting simulcast audition" icon, the present audition general television picture is continually displayed (ST6). [0020] FIGS. 3A and 3B illustrate the general data information display method of the data broadcasting receiver, where the construction of the picture can be changed according to the setting of the viewer. [0021] Generally, because the switching of the picture is differently defined according to the received data information, when the data information picture is displayed, the size of the present audition general television picture decreases or only the data information picture is displayed. But, the viewer can check the size of the data information picture only after switching into the data information picture. [0022] In addition, when the general data information display apparatus of the data broadcasting receiver generates the icon for indicating the data information receipt, before the viewer selects the "television and data broadcasting simulcast audition" item by using the remote-controller or external input device, the viewer can not know the content of the data information received at the present. [0023] In addition, when the viewer selects the "television and data broadcasting simulcast audition" item by using the remote-controller or external input device, the present audition television picture is switched into the television picture and data information picture, wherein an interrupt for replacing the present audition television picture occurs because the size of the present audition television picture has to be adjusted again. Accordingly, the present audition television picture can not be displayed for a certain time. Continue reading...
