By the way, as described above, the operation state of the television receiver operated by the user is displayed as an OSD character to provide a very convenient function for the user. However, the subtitle signal is included in the broadcast signal transmitted from the current broadcasting station to display a predetermined screen. If the OSD characters are output in the middle of the subtitles being outputted, the two characters are overlapped and outputted, thereby preventing the user from identifying the broadcasted subtitles.

Accordingly, the present invention was created in view of the above circumstances, by adjusting the position of the output OSD text so that the text and OSD text is not duplicated if the user selects the OSD text output function in the middle of the current text is output. An object of the present invention is to provide a television receiver with a guide character position control function, which enables a user to recognize a broadcasting subtitle without missing it.

A television receiver having a guide character position control function according to the present invention for realizing the above object includes a video detector for detecting a video signal, and a video processor for processing a video signal detected by the video detector. In a receiver; The analog / digital converter converts and outputs the composite video signal output from the image detector into a digital signal, and the position of the subtitles in the broadcast signal based on the digital video signal output from the analog / digital converter. Recognizable character recognition unit, character position storage unit for storing the position data of the subtitles recognized by the character recognition unit, OSD control data storage unit for storing data according to the output position of the OSD character, and OSD output function is selected Control to output the OSD text at the original position if the broadcast caption does not exist, and control the OSD generator based on the OSD control data so that the OSD text does not overlap with the broadcast caption when the broadcast caption exists. Characterized in that configured to include.

Therefore, according to the above, if the OSD character is output by the user while the broadcasting subtitle is continuously monitored, the OSD character is not overlapped with the broadcasting character so that the OSD character is not outputted. By adjusting the position, the user can recognize the broadcast subtitle without missing it.

Next, an embodiment according to the present invention will be described.

2 is a block diagram showing the configuration of a television receiver having a guide character position control function according to an embodiment of the present invention. In FIG. 1, the same reference numerals are assigned to parts performing the same functions as those of FIG. 1, and detailed description thereof will be omitted.

In the drawing, reference numeral 100 denotes a microprocessor as a control unit for controlling the overall apparatus, and 101 denotes an analog / digital converter 101 for converting and outputting a composite image signal which is detected by the image detector 6 to be output. ) 102 is a character recognition unit that recognizes the caption included in the broadcast signal based on the digital signal output from the analog-to-digital converter 101, and also derives the position data of the caption.

Reference numeral 103 denotes a character position storage unit for storing position data of the subtitles derived by the character recognition unit 102, and 104 controls OSD control data for storing control data such as position, size, and magnification of the OSD characters. It is wealth.

Next, the embodiment according to the present invention having the above-described configuration will be described in more detail.

First, when a user selects a channel using the input means of the remote controller 7, the microprocessor 100 controls the tuner 2 to tune the broadcast signal of the corresponding channel. The broadcast signal is processed by audio and video, respectively, and outputted to each of the speaker 12 and the CRT 17.

The analog-to-digital converter 101 converts the composite video signal output from the image detector 6 into a digital signal and outputs the digital signal.

At this time, when a user selects an OSD output function, for example, a volume up-down function, a channel up-down function, and the like, the microprocessor 100 once drives the character recognition unit 102.

Then, the character recognition unit 102 determines whether the caption image is output based on the digital image signal converted and output from the analog / digital converter 101. In this case, when the caption recognition unit 102 recognizes the caption image from the broadcast signal, the character recognition unit 102 stores the position data of the caption image in the character position storage unit 103 and outputs a predetermined result signal according to the recognition of the caption image. It is output to the processor 100.

Subsequently, the microprocessor 100 reads predetermined OSD control data from the OSD control data storage 104 and drives the OSD generator 14 based on the read OSD control data. At this time, the microprocessor 100 reads the OSD control data stored in the OSD control data storage unit 104 on the basis of the character position data stored in the character position storage unit 103. And OSD characters do not overlap.

That is, according to the above, if the OSD subtitles are output by the user while the subtitles are being output continuously while the subtitles are being output, the corresponding OSD characters do not overlap with the broadcast subtitles. By adjusting the position, the user can recognize the broadcast subtitle without missing it.

In addition, this invention is not limited to the said Example, It can variously deform and implement within the range which does not deviate from the technical summary of this invention.

As described above, according to the present invention, if the user selects the OSD text output function in the middle of the current text is output, the user does not miss the broadcast subtitle by adjusting the position of the output OSD text so that the text and OSD text is not duplicated. It is possible to realize a television receiver equipped with a guiding character position control function that enables recognition without a notice.
