Embodiment

With reference to accompanying drawing, the effective embodiment about television set of the present invention and method for storing caption information thereof is described in detail as follows:

Fig. 1 constitutes block diagram for TV of the present invention, and Fig. 2 is a TV subtitling information storage method flow chart of the present invention, and Fig. 3 is the embodiment diagrammatic sketch of word storing and setting window of the present invention, and Fig. 4 stores the embodiment diagrammatic sketch of word display window for the present invention.

As shown in Figure 1, TV of the present invention comprises that following part constitutes: multiple signals separate by the multiple signals separated part (11) of the video/audio data of multiplexed a plurality of channels and additional information transmission stream; Filter the chapters and sections filter (12) of additional information in above-mentioned multiple signals separated part (11) output; Resolve promptly, analyze the data analysis portion (13) of above-mentioned chapters and sections filter (12) output; The apply flexibly frequency, the ignorant word of user, captions word of data that above-mentioned data analysis portion (13) is analyzed and word are stored in (14b) database of (14c) (14) of the 1st to the 3rd database (14a) respectively; The video/audio decoder (15) of the video/audio data of decoding multiple signals separated part (11) output; Output and other video/audio signal of handling video/audio decoder are the video/audio handling part (18) of real screen output and the output of sound sound; Display part (19) for the vision signal of output video/audio treatment part on picture (18) output; In order to export from the loud speaker (20) of the audio signal of video/audio handling part (18) output; The setting of being undertaken by word storing and setting window according to the user, with the 1st and the 2nd database is benchmark, by the word caption data that above-mentioned data analysis portion (13) analyzes of classifying, is stored in the 3rd database, and, form and store the control part that word dynamically shows by other display window.

At this moment, database (14) also comprises the 4th database that stores the known word of user in order to import.

With reference to Fig. 2 to Fig. 4, the TV subtitling information storage method of the present invention about as above constituting is described as follows:

At first, the present invention has possessed in order to allow the user at TV (screen display) OSD menu, sets the word storing and setting menu of word memory function.

If the user selects word storing and setting menu (30), as Fig. 3, show the storage word successively by finally stored order, in the one side, show the word scope that the user wants to store (apply flexibly frequency, word, an ignorant word that does not store now), and show to possess for the execute key (31) of the execution of selecting the word memory function and termination and abort key (32), in order to retrieve the scroll key (33) that stores word, to eliminate the cancel key (34) that stores word and the OSD window of whole cancel key (35) for a part or whole part.

For this reason, the user can select the word scope at the OSD window as Fig. 3, retrieves and eliminate required word by scroll key, sets the executing state or the abort state of memory function by execute key (31) or abort key (32).

As Fig. 2, at the state of such user's end setup, control part (17) judges whether to obtain the input (S21) as the word stored command key (captions word folder) of remote controller hot key (Hot-key).

Then, above-mentioned judged result (S21) obtains the input of word stored command key (captions word folder), and control part is confirmed the content that the user sets by above-mentioned captions word folder, judges the executing state (S22) that present word stores.

And, above-mentioned judged result (S22), if be in the executing state that word stores now, control part (17) is by above-mentioned demultiplexer (11), chapters and sections filter (12) and data analysis portion (13), analyze by above-mentioned demultiplexer (11), chapters and sections filter (12) and data analysis portion (13), analysis is stored in the caption data of database (14), presses word classification (S23).

Then, control part (17) is input into closed captioning task (24) in order with the word of above-mentioned classification, and by the order of importing, judges whether to be included in the word scope (S25) that the user sets by 3 window.

And above-mentioned judged result (S25) is included in the word of setting the word scope, and control part (17) is stored in the 3rd database (14c) of above-mentioned database (14) with word, that is, and and for the D/B (S26) of storing subtitling word.

At this moment, when the word scope that the user sets was ' applying flexibly frequency ', if above-mentioned word is corresponding to apply flexibly the word that frequency is the 1st database (14a) of benchmark, control part (17) was stored in word the 3rd database (14c) of storing subtitling word, otherwise, do not store.

And when the word scope was ' the ignorant word of user ', with reference to the 4th database, when the word scope was ' the word that does not store ', except that reference the 3rd database, the word storing mode was identical with the situation of ' applying flexibly frequency '.

When carrying out the above-mentioned stage (S26), as Fig. 4, the side in the picture field dynamically shows the word (S26) that stores with the OSD form successively by nearest order.

Both, the word that stores had been presented at top side (40) recently, if store new word again, this word is presented at the top side, and former word moves down (50).

At this moment, by the word stored command key (captions word folder key) in above-mentioned stage (S22), the expression of the OSD of above-mentioned Fig. 4 will disappear again, and word stores and also will end.

Simultaneously, if when the above-mentioned stage, the storage of (S22) word was in ' termination ' state, both, pressed abort key (32) at the setting window of Fig. 3, when memory function is set at abort state, the word that just identical with Fig. 4 form stores till showing now.

But because this moment, the word storage was in abort state, (S27) is different with the above-mentioned stage, with the word that stores till the stationary state demonstration now.

Simultaneously, the user also may wish from the captions information that is presented at picture, stores the captions information in own required field.

For this reason, the invention provides the field memory function.

Promptly, the user utilizes key input mediums such as remote controller, after from the captions field of picture, specifying the field of wishing, by other key (for example, storage key), control part (17) is discerned, and extract phase is answered the captions information of above-mentioned designated field, is stored in the 1st to the 3rd database (14a-14c) the appointment storage art in addition of database (14).

Above-mentioned captions information by user's designated field stores the captions information that has precedence over word and stores.
