According to the present invention, in a television having a caption broadcasting apparatus, when the user sets a desired language and the program being broadcast is broadcast in the set language, the television automatically changes the sound mode so that the user can listen to the broadcasting in the desired language. A language selection method of a broadcast, and in particular, a language selection of a television broadcast that allows a user to select and listen to a specific language only by using information about a broadcast language of an EDS (EXTENDED DATA SERVICE) television program transmitted from a broadcasting station. It is about a method.

At present, the sound of television broadcasting is composed of main language (MAIN) that broadcasts in its own language in voice multiple broadcasting and sub-language (S-AP) that broadcasts in another language. By selecting and switching a specific language using the voice language selection mode key, it is possible to listen to a specific language. However, it is possible to confirm which language is being broadcast for each broadcast only by actually changing the mode. Since the mode selection operation had to be performed, there was a problem that there was considerable inconvenience.

On the other hand, with the recent widespread use of television and the fact that almost all homes have at least one television, television has become an important medium for transmitting information to the general public. Information transmission using television, such as caption / text broadcasting, which has been at the forefront, has gradually started to appear.

In addition, since caption / text can transmit not only contents related to television broadcasting, but also various kinds of information, related parties and developers have used television caption / text broadcasting as various information transmission media.

At the same time, the need for standardization in caption / text information transmission has been increased in order to prevent disordered flooding of information due to the complexity and diversification in using such caption / text broadcasting for information transmission. On February 22, the data to be transmitted to the caption / text broadcasting line, that is, the specification of the contents and transmission method of the EDS, was released as draft EIA-608. In the future, the EDS using the caption / text broadcasting was draft EIA-608. It will be transmitted to the television by the standard of the call.

The present invention is to remove the hassle of language selection by the user in the voice multiple mode of the broadcast program as described above, to provide usability, and stores the language selection mode so that only the language selected by the user can always hear. When the EDS language information data according to the standard of draft EIA-608 is checked every time and any one of the main language and the sub-language of the broadcast program is selected and broadcasted in the stored language, the sound is automatically transmitted to the corresponding mode. It is an object of the present invention to provide a language selection method for television broadcasting that can be listened to only by the language selected by the user.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings of FIGS. 1 to 2.

1 is a schematic block diagram of a caption / text broadcast television for carrying out the present invention.

In a television including a caption / text data slicer and a decoder, a broadcast signal including a caption / text transmitted from a broadcasting station is first received by the tuner unit 10 in the television and is received by the intermediate frequency IC 20 by an intermediate frequency. The broadcasting signal filtered through the intermediate frequency IC 20 is outputted to the image processing unit 30 for various processing for output to the TV screen, and the 21st vertical signal is transmitted by the data slicer 40. Caption / text data including EDS data transmitted during the blanking period is sliced and sent to the decoder 50.

Caption / text data extracted by the data slicer 40 is decoded by the decoder 50 and applied to the microcomputer 60.

At this time, the microcomputer 60 determines whether it is EDS transmission according to the contents of the code input by the decoder 50, and drives the program according to the present invention according to the EDS transmission data.

FIG. 2 is a flowchart of a microcomputer 60 for carrying out the present invention. FIG. 2 (a) is a flowchart illustrating a process of processing EDS data carried on a caption / text broadcast signal.

That is, checking (A) whether the data code decoded by the decoder 50 and inputted is an EDS control code, i.e., 01h or 02h, and then whether the input data code is an EDS carrier, i.e., 06h. Check step (B), and if the two steps (A, B) are satisfied, then the same data is input to check whether the language currently set by the user and the broadcast language are the same (C). Otherwise, the process returns to step A and, if the same is the case, the step D of converting the voice mode to broadcast the corresponding language.

FIG. 2 (b) is a flowchart showing the processing flow of the microcomputer 60 for storing the language selected by the user.

(A) starting with the key input device 70 and the language setting key input installed on the remote controller, and loading the currently selected number among the numbers assigned to each language, and increasing the number from the current language number. Selecting a set language (B), and storing the number of the selected language, and at the same time outputting the OSD to the screen to inform the user of the selected language (C).

Based on the operation and effects of the present invention according to the processing flow made as described above in more detail as follows.

First, according to the transmission method of EDS data published by draft EIAS-608, EDS data is transmitted together with caption / text data in the 21st vertical blanking period of a television broadcast signal. While all of Field 2 is used, EDS data uses only Field 2.

In addition, the EDS transmission is composed of a control code for indicating that the EDS transmission is beginning or being transmitted, a carrier code for informing information about the content of the data to be transmitted, and a data code containing actual information.

The details are shown in detail in draft EIA-608. Here, the codes used in the present invention describe the codes used in the present invention and control codes indicating that the EDS information is being started or being transmitted, and 01h and 02h. The EDS carrier code indicating the language of the broadcast program is 06h, and the EDS language data is composed of two character codes, where the first code indicates information on the main language and the sound mode of the main language, and the second code Information about a sub language and a sound mode of the sub language are shown.

In this case, bits b5-b3 of the first and second character codes represent language information, bits b2-b0 represent sound modes of each language, and the language codes represented by the bits b5-b3 are as follows. same.

The EDS language information configured as described above is serviced using field 2 of caption / text broadcasting, which is received by the tuner unit 10 like the broadcast signal, frequency filtered by the intermediate frequency IC 20, and the data slicer 40. Sliced caption / text broadcast data is sent to the decoder 50.

The microcomputer 60 determines that the EDS is being transmitted according to the input code decoded by the decoder 50 and performs the command of the present invention. That is, the input control code is 01h or 02h, and the carrier code is In the case of 06h (A, B), the next input EDS data is judged and processed by language information. From the EDS language information, information on the language of the broadcast program is checked, and the main language or sub-language is currently set. If there is a language that matches the current language (C), the current sound is changed to the main language mode in which the set language is broadcast, or the sub-language mode is changed (D).

The changed language mode is output to the screen through the OSD processor 90, and the control signal for the changed mode is output to the voice processor 110.

Next, when the user wants to select a language, the user inputs a language setting key installed on the key input device 70 or a remote controller (not shown), and the remote control signal is received by the remote control receiver 80 to receive a microcomputer ( 60), the microcomputer 60 performs a language selection mode upon reception of the key signal.

That is, it loads the number of the currently set language (A), provides a language mode that can be selected while increasing the number from the set language number one by one, so that the user can press a desired language number, and is set as described above. When a language is selected (B), the number of the selected language is saved and the language is displayed on the screen by the OSD (C) so that the user can check the language selected by the user once again.

As described above, the language selection method of the television broadcast of the present invention stores the language selection mode so that only the language selected by the user is always listened, and stores the EDS language information data according to the standard of the draft EIA-608. When either the main language or the sub language of the program being checked and broadcasted is selected and broadcasted in the stored language, the sound is automatically changed to the line-by-line mode so that only the language selected by the user can be listened to. Eliminates the hassle of language selection by the user, and when the desired language is broadcast, you can listen to the program broadcast in the language at any time has the effect of helping the language practice.
