Embodiment

Below, the embodiment to subtitling view level setting method of the present invention is elaborated with reference to the accompanying drawings.

At first, the formation element among each figure has all been added corresponding symbol, shows in different figure even should note identical formation element, also might use identical symbol.

Simultaneously, for the present invention is described, under the prerequisite that does not influence purport of the present invention, just do not elaborate for known relevant formation or function.

Fig. 1 is that the digital video playback devices that is applicable to subtitling view level setting method of the present invention constitutes skeleton diagram.

At first, subtitling view level setting method of the present invention can be applicable to various types of digital video playback devices such as DVD player.As shown in Figure 1, digital video playback devices 100 comprises following each several part: CD 10, light picker 11, Play System 12, audio decoder 13, Video Decoder 14, text decoder 15, memory 16, microprocessor 17 and OSD generating apparatus 18 etc.

Here, microprocessor 17 can be according to user's request, before the captioned test of in CD 10, playing the earliest, perhaps in the head part, adding subtitling view level identification literal under the situation that has the head part, after this, when playing CD 10, with before the captioned test or the head partial memory subtitling view level identification literal serve as according to control output caption data.Here, subtitling view level identification literal not only can be inserted into before the captioned test of playing the earliest or the head part in, also can deposit the front-end and back-end of the caption content of the subregion that does not show output captions content of text in.

Simultaneously, in the data file of playing CD 10 stored, for example playing AVI, WMA, during DivX files such as MPEG, control device 17 can controls playing system 12 move, as shown in Figure 2, the DivX file of CD 10 stored with the voice data of the video data of MPEG-4 form and MP3 format according to an A/V file (Audio ﹠amp; Video File) stores, also store the subtitle texts (Text File) such as (Subtitle) of DVD.Here, text comprises having smi, srt, txt, sub, ssa, the file of extension name such as ass.

In addition, the DivX voice data that audio decoder 13 can read out Play System 12 is decoded according to MP3 format, and the audio frequency of output high tone quality, the DivX video data that Video Decoder 14 can read out Play System 12 is decoded according to the MPEG-4 form, and the video of output high image quality.

Simultaneously, text decoder 15 can utilize the text-converted table (Text Conversion Table) of a kind of any language (Language), after the DivX text data decoding that Play System 12 is read out is converted to corresponding language-specific character image, by Video Decoder 14 on the main video image of playing output with the overlapping demonstration of captions image format.

In addition, as mentioned above, microprocessor 17 identifies and is inserted into the subtitling view level identification literal that the captioned test of playing the earliest is preceding or the head part is interior when reading the DivX text, and according to subtitling view level identification literal, captioned test is exported or is not exported in control.

But, when the output captioned test, as shown in Figure 2, Fig. 2 is the running figure that plays the captioned test file, microprocessor 17 must be selected the text-converted table with corresponding any one language of country code from a plurality of text-converted tables of memory 18 stored management, for example select English (Language-EN), French (Language-FR), Korean (Language-KR) text-converted table etc.Text decoder 15 utilizes selected English text conversion table, and text data is converted to the English letter image, and plays output.

Fig. 3 is the action flow chart that is used to illustrate subtitling view level setting method of the present invention.

Step 302, at first, the user utilizes subtitle file editing equipments such as computer, view level is discerned literal, for example " sex (SEX) " or contents such as " 19 years old " are inserted into position (a) before the captioned test of playing with the form of subtitle file the earliest shown in Fig. 4 (Fig. 4 is the view that shows captioned test file pattern) with the form of text, perhaps be inserted into the position, front-end and back-end (b) of not wanting the caption content exported, generate the view level subtitle file that restriction shows captions.

Here, the form of subtitle file shown in Figure 4 is shown as the subtitle file form of expansion ＂ smi ＂ by name, as shown in Figure 4, it is by constituting with the lower part: show the marker character " " SAMI " " that subtitle file begins and finishes, " "/SAMI " ", the marker character " " HEAD " " that shows the head part, " "/HEAD " ", the marker character " " Title " " that shows title, " "/Title " ", the marker character " " STYLE " " that shows the captions type, " "/STYLE " ", the marker character " " BODY " " of demonstration captioned test content, " "/BODY " " etc.

Therefore, when the user wishes that whole captioned test contents do not show as captions, just can be shown in (a) among Fig. 4, view level identification literal ＂ SEX ＂ is inserted in the position before the captioned test of playing the earliest, perhaps when the user wishes that part captions content of text does not show as captions, just can be shown in (b) among Fig. 4, insert view level identification literal " SEX " respectively in the front-end and back-end of relevant captioned test, the edlin of going forward side by side is stored as the view level subtitle file then.

Step 304, as mentioned above, at the video file, audio file and the subtitle file inediting subtitle file that constitute the DivX file, and after generating new view level subtitle file, the user judges whether to be in broadcast DivX file mode earlier in order to watch video image.

Step 306, when requiring to play the DivX file, microprocessor 17 is play the requirement of DivX file according to the user, read out the DivX file of CD 10 stored by Play System 12 after, utilize audio decoder 13 and Video Decoder 14, voice data and video data are exported with the form of high tone quality audio frequency and high image quality video, simultaneously, subtitle file is stored in the memory 16, will has the caption content and the video image overlapping broadcast on main video image synchronously that constitute as shown in Figure 4.

Step 308, when playing subtitle file, microprocessor 17 judge (a) that whether exist in the captioned test content among Fig. 4 and (b) shown in view level discern literal.

Step 310, if there are view level identification literal such as ＂ SEX ＂ or 19 years old ＂ of ＂ in the captioned test content, for example, shown in (a) among Fig. 4, if before the captioned test of playing the earliest, there is view level identification literal, just control does not show the content of exporting whole captioned tests, if shown in (b) among Fig. 4, there is view level identification literal in the front-end and back-end in certain zone, just control, only in the interval that has view level identification literal, do not show the content of exporting captioned test.

Step 312 in addition, does not exist in the captioned test content under the situation of view level identification literal fully, and microprocessor 17 is just just like the overlapping demonstration output text subtitle images on main video image that continues toward ground.Promptly, for playing captioned test, microprocessor 17 retrieves setting various countries' mother tongue lockings (Parental Lock) level other standardization country code (Country Code) in memory 16, for example retrieve the country code (USA) of representing the U.S., simultaneously, from the multiple text-converted table of memory 16 stored, retrieve and the corresponding text-converted table of country code (USA), for example retrieve English (Language-EN) text-converted table, and control text decoder 15 operations, utilize the English text conversion table, the text data decoding that Play System 12 is read out is converted to the English letter image, and carries out the operation of a series of broadcast DivX texts.

As mentioned above, according to the present invention, can realize following subtitling view level setting method: in the title picture that receives by Digital Television or download by the internet, in the caption content interval that needs restriction captions show, set view level identification literal, when the play title picture, discerning literal with the view level that exists in the subtitle file is foundation, shows the output captions selectively.
