{APPARATUS FOR DISPLAY OF DATA INFORMATION}

The present invention relates to a data information display device, and more particularly, to separate an auxiliary output device by separating data information such as OSD (On Screen Display) information and subtitle information from a main screen in a video device such as a broadcast playback device. The present invention relates to a data information display apparatus capable of outputting an image through a video.

As is well known, the broadcast reproducing apparatus is a device for receiving and reproducing a broadcast signal transmitted from a broadcasting station, and is a PVR (Personal) which records and reproduces information on a television system, a set-top box, and a hard disk built into the television main body. Video Recorder).

In conventional analog television broadcasting, video signals to be transmitted are modulated by AM or FM and transmitted through radio waves or cables. With the recent development of digital technologies such as digital image compression and digital modulation and demodulation, the standardization of digital television (DTV) broadcasting has advanced, and the existing terrestrial, satellite, and cable broadcasting have been digitized based on the Moving Picture Experts Group (MPEG). .

As such, digital broadcasting can provide higher quality of service than analog service according to the development of digital video / audio compression technology and digital transmission technology, and can transmit multiple broadcast programs in the same bandwidth, digital communication media and digital storage. There is an advantage in that interoperability with the media can be improved.

Meanwhile, a broadcast signal received through a digital broadcast channel includes not only a video signal and an audio signal, but also a data signal, and the data signal is displayed on the main screen by an OSD information output method, which is a kind of graphical user interface (GUI). Through video output.

In addition, relatively recent broadcast contents are increasingly used for subtitles, and subtitle information for this is mixed into a video signal, received, and processed together with the video signal to be output through a main screen.

It is configured to include the output unit 800.

The first image output unit 600 and / or the second of the subtitle information included in the image signal and / or the OSD information by the data signal are configured by the data information display apparatus according to the present invention configured as described above. A process of displaying through the image output unit 800 will be described. In the following description, a process of receiving and reproducing a general video signal will be omitted, and a process of displaying caption information and OSD information will be described with reference to FIGS. 4 and 5.

Referring to FIG. 4, a process of displaying caption information according to an embodiment of the present invention will be described below.

First, when a separate display for caption information is selected and requested through the user input unit 300, the controller 400 generates a control signal for commanding a separate display of the caption information from the main screen and generates data of the signal processor 500. The control signal provided to the processing unit 530 and provided to the data processing unit 530 is input to the display positioning unit 535, and the display positioning unit 535 is based on the control signal provided from the control unit 400. The setting state of the split display function for the caption information is checked (S911).

When the caption separation display function is set based on the result of checking in step S911 (S912), the caption information extracting unit 531 separates and extracts caption information from the image signal decoded by the image processing unit 520 (S913). Subtitle display data corresponding to the extracted subtitle information is generated (S914). Here, the caption information extracting unit 531 may identify and extract caption information by using an information identifier included in the caption information indicating that the caption information is caption information.

The display position determiner 535 determines the type of the caption information based on the form identifier included in the caption information extracted by the caption information extractor 531 and indicates the caption type. Decide That is, it is determined whether the subtitle display data is to be displayed through which of the graphic display 810 and the sentence display 820 constituting the auxiliary output device 801.

The display position determiner 535 provides the caption display data to the second image output unit 800 together with the positioning signal so that the caption information can be displayed corresponding to the position where the display of the caption information is determined. The image output unit 800 outputs and displays the caption display data through one of the graphic display unit 810 and the sentence display unit 820 based on the positioning signal (S915).

The display process of the OSD information according to an embodiment of the present invention will be described with reference to FIG. 5 below.

First, when a separate display for OSD information is selected and requested through the user input unit 300, the controller 400 generates a control signal for commanding a separate display of the OSD information from the main screen, thereby generating data of the signal processor 500. The control signal provided to the processing unit 530 and provided to the data processing unit 530 is input to the display positioning unit 535, and the display positioning unit 535 is based on the control signal provided from the control unit 400. The setting state of the separate display function for the OSD information is checked (S921).

In addition, when the output of the OSD information is selected (S922), the OSD processing unit 533 separates and extracts the ODS information from the data signal separated and input by the demultiplexer 510, and extracts the OSD display data corresponding to the extracted OSD information. It generates (S923).

The display position determiner 535 displays the OSD through any one of the first image output unit 600 and the second image output unit 800 based on the setting state of the separate display function for the OSD information confirmed in step S921. Determines whether to display data.

In addition, the display position determiner 535 may provide the output information to any one of the first image output unit 600 and the second image output unit 800 so that the OSD information can be displayed corresponding to the position where the display of the OSD information is determined. Provides OSD display data. In this case, since the separated display function of the OSD information is selected at step S921 (S924), the OSD display data is provided to the second image output unit 800.

Then, the second image output unit 800 outputs and displays the OSD display data through any one of the graphic display 810 and the sentence display 820 (S925). Here, the OSD information may be implemented to be output and displayed through any one of the graphic display unit 810 and the sentence display unit 820 based on the positioning signal of the display position determiner 535 similar to the subtitle information.

If the separate display of the OSD information is not selected and requested through the user input unit 300, the display position determiner 535 provides the OSD display data to the first image output unit 600 and the first image display unit 600. The image output unit 600 outputs the OSD display data together with the main screen corresponding to the image signal through the main screen output device 610 (S926).
