Abstract
The present invention discloses an adaptive subtitle adjustment method for a video player. According to the technical scheme of the invention, a camera is arranged on the video player to capture an image in the face of the video player during the playing process. After that, the image is parsed. According to the size of a human face image in the above image, the distance between the human face and a screen can be calculated. According to the calculated distance, the size of the subtitle is adjusted. Meanwhile, the audio information and a subtitle file of an audio-video file are acquired at the same time, and the audio information is parsed to generate a dialogue time table. According to the dialogue time table, the playing time of the subtitle file is adjusted, so that a subtitle time table is kept consistent with the dialogue time table. The above method can automatically adjust the size and the time of the subtitle, and the user experience is good.
Description
Technical field
The present invention relates to audio and video player field, particularly relate to a kind of method that audio and video player self adaptation captions adjust.
Background technology
Captions (subtitlesofmotionpicture) refer to, with non-visual contents such as the dialogues in written form display TV, film, stage works, also refer to the word of films and television programs post-production.The spoken title of films and television programs, is generally present in below screen, and the captions of theatrical production, then may be shown in stage both sides or top.
After American has opened the beginning, captions are popularized rapidly America and Europe the most with crushing force.Pixel rigorous abnormal Vienna State Opera also frankness in people mind is adopted；Florida grand theater in Miami especially and then have employed English and Spanish bilingual subtitles.At Germany Wagner Music Day location Bai Luyite, Wagner German only recognized by " Temple of God " theater created, and does not the most give captions place to stay, and such exception is phoenix feathers and unicorn horns really.
Being shown in captions mode by the voice content of program, the spectators that audition can be helped more weak understand programme content.It addition, captions can be used for translating foreign language program, allow and do not understand the spectators of this foreign language, the vocal cords of original work can be heard, understand programme content simultaneously.
Overcome language barrier, the easiest for singer, such as pavarotti all one's life with the classical opera of the Italy that deduces as own duty, never set foot in moral, Russia, west, English, the uneven spectators of the opera of Mei Deng state, still more L proficiency.The appearance of captions, adds the non-mother tongue opera affinity to spectators, and the particularly success to " the Ka Jiaka Barnes & Noble baby " of those directorys rarely known by the people such as Ya Naxieke and " caprice " of Astrid Strauss is showed and performed meritorious deeds never to be obliterated.But 2005, the United Kingdom National theatre with the whole-colored English directory as characteristic also determined to use English subtitles, but attracts the sound of a piece of query.The Graham Sodd method of investing dimension gram the most held office at theater is painful to this, it is believed that this is that one appreciatory to spectators " is anaesthetized ", even have issued the language of the exasperation " demolishing " theater.But take the post as today of president at him, though there are some unwillingness in the heart to captions, but under the pressure of trend of the times, also have to give tacit consent to this present situation.
The most popular subtitling format, is divided into graphical format and text formatting two class.
Graphical format captions are made up of idx and sub file, idx is equivalent to index file, the inside includes timing code and the attribute of Subtitle Demonstration that captions occur, sub file is exactly caption data itself, owing to being picture format, so bigger, easily more than 10M (but we can by boil down to rar file, with the same less than compression under the support of unrar.dll, but a lot of space can be saved).Idx+sub can deposit the captions of polyglot, can select easily playing when.
The extension name of text formatting captions is typically srt, smi, ssa or sub (the same with graphical format suffix above, but data form is different) because being text formatting, so small-sized, the most a hundred or so come KB.Wherein srt text subtitle is most popular, because it makes and amendment is the simplest :+one captions of a time code.
The captions of existing audio and video player typically play out only in size set in advance and time, and the size that there will be word sometimes is not fully up to expectations or there is the situation of mismatch between captions and sound, at this time can only manually regulate, very inconvenient.
Patent " audio-visual caption playing system and method " (application number: 201210084901.4 applyings date: 2012-03-27) discloses a kind of audio-visual caption playing system, it is applicable to a DLNA environment, including: a server, there is provided an image file according to a DLNA agreement, and require that information provides the caption information corresponding to above-mentioned image file according to captions；And a playing device, above-mentioned image file is received according to above-mentioned DLNA agreement, serve with an ICP/IP protocol and state captions requirement information to above-mentioned server to receive above-mentioned caption information, and integrate above-mentioned image file and above-mentioned caption information to play audiovisual materials, an image file that can simultaneously play audiovisual materials and the method system of independent subtitle file can be provided by server and playing device, help user when playing film, image file and its independent subtitle file of audiovisual materials can be play simultaneously.
Although this patent gives the system and method for a kind of caption playing, but does not solve to be automatically adjusted the size of word in captions and the problem of captions time.
Summary of the invention
The technical problem to be solved is for defect involved in background technology, it is provided that a kind of method that audio and video player self adaptation captions adjust.
The present invention solves above-mentioned technical problem by the following technical solutions:
