[TF]A new method to extend subtitles

    For most of the videos, there are subtitles. Sometimes people will stare at the subtitle and want more information. They may not understand the term in it, they may want to know more about the phrase, or they may just want to know whether some character or scene will show up later again. Currently, there is no efficient and user-friendly way to do it.

    This invention discloses a method to extend subtitles. It also includes the method to detect user's selection in subtitles, show the extended content and remember the watching experience. It can be used but not limited to video web site and media player app.

    When user is watching the video with subtitle, he can select the phrase that he is interested about to get more information. To make the selection to be easier, the invention will slow down the display speed when detecting user is touching the display area where subtitle shows. After user selects part of the subtitle, the invention will show the extended info about the phrase, e.g. the explanation of the phrase, the snapshot of the segment that contains the same phrase later, related info in the internet, or the advertisement matching the phrase. If user wants to resume the playing, he just clicks the subtitle area again, video play will be recovered. If user wants to check the extended content, he just moves the finger to the extended content, then the main screen will show the extended content. The invention also allows user to customize whether he wants the watching process is remembered. It means when user watches the same video again, the invention will show extended content option at the same time of the timeline.

    To detect the text of user's selection, the invention first identifies whether there is independent subtitle. If the answer is yes, the invention checks current time in the timeline and find the relative sentence in the subtitle file. With simple OCR mechanism, it can detect the location of the phrase in the entire sentence. Then it can detect user's selection easily. If the video only has embedded subtitle, the invention uses OCR mechanism compounded with voice recognition mechanism to identify the selected text.

    Below is an example about how the invention works. Assume a user is watching the video in smart phone, at 2:35 of the timeline, he is curious about the name shown in the subtitle. So he just clicks the subtitle and the play speed decreases so that the strings in subtitle

is easier to be selected. Then he swipes over the area and the invention retrieves the text from it. It searches the internet according...
