Problems solved by technology
However, the multimedia recording technology used in the traditional multimedia interactive technology is usually limited to the recording of several common media information, such as audio and video, etc., but during playback, the synchronization between various media cannot be achieved.
For example, media information includes PPT documents and corresponding videos. When a user browses a PPT, the video cannot be linked with the PPT, so that when the user turns to a certain page of the PPT, the video is automatically positioned to the corresponding playback position; similarly, when When the user browses the video, the PPT cannot locate the corresponding page along with the playback position of the video
Therefore, existing recording devices have problems such as a single media format and poor interactive retrieval capabilities among media information.
A recording device or method that can truly record a variety of media information, retain the association between various media formats, and realize the interaction between various media formats has not yet appeared
[0003] At the same time, when recording multiple media, due to reasons such as time asynchrony of each media recording device, it will be difficult to synchronize the media when playing multimedia information

The invention provide a simultaneous recording method for a variety of media, comprising a recording step in which media files of a variety of formats are recorded, and a simultaneous marking step in which the recording progress of other types of media files is recorded when a predetermined key event happens to a media type. The invention further provides a method for simultaneously playing a variety of media files recorded by the method. The involved media files are played according to the recording progress of the media files recorded when each key event happens. The invention further provides a recording and playback device employing the method.
Description
technical field [0001] The invention relates to a multimedia recording method and system, in particular to a method and system capable of synchronous recording of multiple media and synchronous playback. technical background [0002] With the development of information technology and electronic technology, multimedia interactive technology has been applied in various exhibition halls, such as: museums, science and technology museums, enterprise exhibition halls, school classrooms and so on. However, the multimedia recording technology used in the traditional multimedia interactive technology is usually limited to the recording of several common media information, such as audio and video, etc., but during playback, the synchronization between various media cannot be achieved. For example, media information includes PPT documents and corresponding videos. When a user browses a PPT, the video cannot be linked with the PPT, so that when the user turns to a certain page of the PP...
