Description

  The present invention relates to a video display device such as a television receiver that receives a digital broadcast.

  For television receivers that receive digital broadcasts, there is no specific prior art document, but in general, video signals such as movies sent with subtitle signals from broadcast stations are sent. The received information is decoded as it is and displayed faithfully.

  By the way, the language of Japanese has various expression methods such as hiragana, katakana, and kanji, and is considered difficult compared to other languages. Especially for foreigners who want to learn Japanese, kanji is a big barrier to learning Japanese. In addition, there are many kanji characters that even Japanese people cannot read if they are young children.

  When viewing the contents of a program with subtitles in Japanese, it may not be possible to read all the subtitles depending on the viewer. However, adding phonetics to all kanji has the problem of becoming annoying or excessive service for those who want to learn Japanese.

  The present invention has been made in view of such a situation, and in a video display device such as a television receiver to which a video signal including a caption signal is input, a viewer can add a phonetic to a kanji according to his / her level. The purpose is to do so.

  In order to solve the above problems, the present invention provides an input unit to which a video signal including a caption signal is input, a signal separation unit for separating a caption signal from the video signal input to the input unit, and the signal separation A subtitle processing unit that selects a character from the subtitle signal separated in the section and adds a phonetic to a necessary kanji, and a memory that classifies and stores kanji for adding a furigana in a predetermined level unit, The subtitle processing unit is configured to read data from the memory and add a phonetic to a necessary kanji in accordance with a viewer's level selection.

  According to the present invention, subtitles in Japanese kanji can be provided in a form that matches the level of the viewer's kanji, and help the viewers who cannot read kanji, such as children and foreigners, to understand the content of the subtitles. can do.

  Hereinafter, an image display apparatus according to an embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 is a block diagram showing the overall configuration of a video display apparatus according to an embodiment of the present invention, and FIG. 2 is a block diagram showing the configuration of the main part thereof. In the figure, 1 is an antenna, 2 is a tuner for receiving a digital broadcast as an input unit to which a video signal including a caption signal is input, and 3 is a signal separation unit for separating the caption signal from the video signal received by the tuner 2. Reference numeral 4 denotes an MPEG decoder for demodulating the video signal separated by the signal separation unit 3, and 5 selects a character from the subtitle signal separated by the signal separation unit 3 to add a phonetic to a necessary kanji. A caption processing unit, 6 is a phonetic setting unit for the viewer to select a level at which he / she wants to add furigana, 7 is a memory which stores kanji for adding furigana classified into predetermined levels, and 8 is the MPEG This is a video signal generation unit for synthesizing signals from the decoder unit 4 and the caption processing unit 5 and displaying them on the display unit 9.

  Further, as shown in FIG. 2, the caption processing unit 5 includes a furigana separation unit 5A that separates a body signal from a caption signal into a body 5B and a phonetic 5C, and a phonetic composition unit 5D that combines the body 5B and a phonetic 5C again. According to the viewer's level selection, data is read from the memory 7 and furigana is added to necessary kanji.

  In such a configuration, the tuner 2 receives the signal of the channel selected by the viewer from the antenna 1. The output of the tuner 2 is sent to the signal separation unit 3, and the signal separation unit 3 separates the video / audio data and the caption data from the video signal sent from the tuner 2. The video / audio data is sent to the MPEG decoder unit 4, and the caption data is sent to the caption processing unit 5.

  FIG. 3 is a flowchart for explaining the above configuration. As shown in FIG. 3, the subtitles with furigana separated from the video are further separated into main text and furigana. Next, when the viewer has not selected the phonetic display mode in advance, the phonetic is deleted and the subtitle without the phonetic is displayed.

  If the phonetic display mode is selected, the conversion value of the subtitles, that is, the setting of the phonetic conversion level for how much kanji is added is read, and the kanji is searched from the beginning of the sentence. Next, it is determined whether or not the searched kanji is higher than the set level, and if it is determined that the kanji is higher than the set level, it is determined that furigana addition is necessary and the separated furigana is synthesized again. . If it is determined that no furigana addition is necessary, no furigana synthesis is performed. Thereafter, it is determined whether or not the subtitle has been completed. If the subtitle has been completed, the subtitle is displayed. If the subtitle has not been completed, the flow returns to the kanji search flow again to perform the next kanji search again.

  More specifically, when the caption conversion mode is selected by the phonetic setting unit 6, the caption processing unit 5 converts the caption data sent from the signal separating unit 3 into the text 5B and the phonetic 5C by the phonetic separating unit 5A. Separately, the kanji for which the furigana is required is discriminated according to the level set by the furigana setter 6. At this time, the caption processing unit 5 makes a determination while referring to the data of the level-specific kanji level table stored in the memory 7 as shown in FIG. A kanji character determined to require a furigana is added with a furigana by the furigana synthesis unit 5D. The subtitle data with the furigana added is sent to the video signal generation unit 8, where the video / audio from the MPEG decoder unit 4 is combined with the subtitles and sent to the display unit 9 as a video signal. As a result, as shown in FIGS. 5 to 7, the display unit 9 displays subtitles with kanji added to the kanji.

  For example, when the user selects the phonetic display mode level 1 using the phonetic setting device 6, the phonetic is added to “mountain”, “village”, “main”, and “taka” as shown in FIG. As shown in FIG. 6, furigana is added to “main” and “taka”, and “mountain” and “village” are kanji characters at a set level or lower, so no furigana is added. When level 3 is selected, furigana is added only to “taka” as shown in FIG. 7, and when level 4 is selected, there is no corresponding kanji, so no furigana is added as shown in FIG. . In other words, the viewer can learn how to read kanji while reading the subtitles by adding the phonetics to the subtitles according to his / her level.

  Here, as shown in FIG. 9, a user level may be provided as a setting level so that a dedicated Kanji level can be set. For example, if a user who can read “worship” but cannot read “string” is set to level 3, furigana is added to both “worship” and “string”. After the program is over, you can delete unnecessary furigana by setting so that you don't wield the “worship” next time.

  Also, when the phonetic non-display mode is selected by the phonetic setting unit 6, the caption processing unit 5 separates the caption data sent from the signal separating unit 3 into the text 5B and the phonetic 5C by the phonetic separating unit 5A, and combines the phonetics. Only the text 5B is sent to the video signal generation unit 8 without adding the furigana in the unit 5D. In the video signal generation unit 8, the video / audio from the MPEG decoder unit 4 and the subtitle are combined and sent to the display unit 9 as a video signal. As a result, as shown in FIG. 8, the display unit 9 displays the subtitle information sent from the broadcasting station with the furigana deleted.

  Here, in the present embodiment described above, the level is divided into four stages as shown in FIG. 4. However, for example, “convert all characters” or “convert characters at junior high school level or higher” may be used. .

  As described above, according to the present invention, it is possible to provide subtitles in Japanese kanji, which are difficult, according to the level of the viewer's kanji, and provide a video display device that is useful for learning Japanese. can do.
