KR970078479A - Title: Selectable caption broadcasting, receiving apparatus and method with dual metabolic caption transmission function - Google Patents

Abstract

The present invention relates to a viewer-selectable caption broadcasting, receiving apparatus, and method, and more particularly, to a caption broadcasting apparatus, a receiving apparatus, and a method for receiving a dual metabolism information, And if the mode is selected by the viewer after storing in the respective storage units, the character data of the corresponding mode is synthesized with the video signal and then output to the screen.

Therefore, in the present invention, it is possible to display not only the familiar English but also a variety of third-language foreign language information such as German and French, on a television screen when watching a movie.

Claims (4)

A viewer-selectable caption broadcasting apparatus for inserting and transmitting caption information in any one horizontal line which does not affect a broadcasting signal for every field of a television signal, the apparatus comprising: a Korean alphabet information input means for inputting Korean alphabet information; A foreign language dialog information input means for inputting foreign language dialog information; Odd field detection means for receiving a count value of the synchronization counter means and detecting an odd field by the count value; Switching means driven by the three output signals to the odd field detection means and selectively outputting the Hangul Metabolic Information or the foreign language dialog information; Character code generation means for converting the metabolism information output from the switching means into a document code; A data packet modulating means for modulating the character code by a digital modulation method; And transmission means for synthesizing the modulated data packet with a video signal and transmitting the modulated data packet. A viewer-selectable subtitle broadcasting method for inserting subtitle information into an arbitrary horizontal line that does not affect a broadcasting signal for every field of a television signal and transmitting the subtitle information, the method comprising: receiving a count value of a synchronous counter to be transmitted; Determining whether the counted value is an odd number; If the odd number is an odd number in the determination step, inputting the Korean alphabet information; Inputting foreign language dialog information by recognizing that the even field is an even field in the determination step; And converting the meta information into a video signal and synthesizing it with a video signal, and transmitting the encoded video signal. A receiving apparatus of a viewer-selectable caption broadcasting in which caption information is inserted and transmitted on any one horizontal line that does not affect a broadcasting signal for every field of a television signal and the viewer selectively displays the caption information upon reception, A Korean language metabolism information storage unit for storing metabolism information; A foreign language dialogue information storage unit for storing foreign language dialogue information; A sequence input means for selecting a function related to a subtitle; The character code received by the analog / digital conversion means is checked and stored in the Korean-language metabolism information storage unit if it is the Korean-language metabolism information, and if the foreign-language metabolism information is stored in the foreign-language metabolism information storage unit, And a caption control means for reading the character data from the font ROM in accordance with the metabolism information read out from the corresponding storage portion according to the mode selected by the control means and displaying it on the screen. Receiving apparatus for a viewer-selectable caption broadcasting. A method of receiving a viewer-selected caption broadcasting in which caption information is inserted and transmitted on any one horizontal line that does not affect a broadcasting signal for each field of a television signal and the viewer selectively displays the caption information upon reception, Extracting a caption signal of a video signal of the television signal; Reconstructing the extracted caption signal into digital data; Detecting an error of the recovered data; Checking the data to determine whether it is the Korean alphabet information; Reading the character data of the Hangul dialog information from the font ROM and storing the read character data in the Hangul dialog information storing unit; Reading the character data of the foreign language dialog information from the font ROM and storing it in the foreign language dialog information storage if the foreign language dialog information is determined in the determining step; Checking whether the mode selected by the command input means is a Hangul dialogue mode; Reading character data from the Hangul Metabolic information storage unit in the Hangul dialog mode in the checking step; Reading the character data from the foreign language metabolism information storage unit if the foreign language ambassador mode is selected in the checking step; And synthesizing the character data with a video signal and then outputting the synthesized video data on a screen. ※ Note: It is disclosed by the contents of the first application.
