Embodiment 1

[0018] Embodiment 1: a kind of audio-visual and graphic text synchronous playing method of the present embodiment, such as figure 1 and figure 2 shown, including the following steps:

[0019] Establish synchronization information between video and audio content and graphic content, associating frames of video and audio content with the beginning and end of paragraphs of graphic content, or the beginning and end of sentences, or words, words, or images;

[0020] Video, audio and graphics are displayed in two windows or two areas of a window, and the window or area can be hidden;

[0021] The player supports video and audio mode (only play audio and video), graphic mode (only display pictures and / or text), mixed mode (video and audio content is played while graphic content is also displayed synchronously), and supports video and audio to Automatic synchronization of graphics and graphics to video and audio;

[0022] Manual switching means that the user pauses or stops the vi...

Embodiment 2

[0029] Embodiment 2: A kind of audio-visual and picture-text synchronous playing method of the present embodiment, except the mode that embodiment 1 comprises, playback device also supports audio mode, only plays audio content under the audio mode, and the screen of playback device does not display Video content and graphic content. The playback device is connected to the body controller of the car. When it is detected that the speed of the car is not 0, if the current mode is graphic mode, audio-visual mode or mixed mode, it will automatically switch to audio mode to prevent the driver from being distracted. to the screen of the playback device to maximize driving safety. When the vehicle speed becomes 0 again and exceeds 30 seconds, the playback device automatically switches from the audio mode to the previous mode, and the driver can continue to watch. When switching between different modes, the content being played is kept in sync, that is, the progress after switching is...

Abstract

The invention discloses a video-audio and picture-text synchronous playing method, comprising the following steps of: at first, establishing a synchronous relation between video-audio contents and picture-text contents through a compiling system so as to ensure that frames of the video-audio contents correspond to pages, paragraphs and sentences of the picture-text contents; packing the synchronous relation as a playing control instruction with the video-audio contents and the picture-text contents together so as to form an independent media packet file; and when a user obtains the media packet file, encrypting the video-audio contents, the picture-text contents and the control instruction respectively by a player. When the media package file is played, the user can select playing modes which comprises a video-audio mode and a picture-text mode. When the user converts the playing mode in a watching process, a playing point of a converted content corresponds to a non-converted content. The player synchronizes playing schedules of the video-audio contents and the picture-text contents according to the control instruction. The video-audio and picture-text synchronous playing method provided by the invention is applicable to various playing devices.

Description

technical field [0001] The invention relates to the playing and switching of media files, in particular to a method for synchronously playing video, audio and graphics. Background technique [0002] At present, multimedia players such as computers, smart phones, and smart terminals can play video and audio content, and can also display pictures and text content. At present, a large number of novels and comics have been adapted into movies, TV or animation, and many novels have been recorded as audio novels.
