File comment information generation method

Abstract

Embodiments of the invention relate a file comment information generation method. The method comprises the following steps: receiving a to-be-commented file by a host computer; obtaining audio data according to a time shaft and acquiring dot matrix image data acquired by a device in a dot matrix area corresponding to the to-be-commented file; adding a time strap to the audio data so as to generate an audio file; recognizing the dot matrix image data so as to obtain a recognition track; and generating the audio file and the recognition track into comment information and injecting the comment information into the to-be-commented file so as to obtain a standardized file and play the standardized file. According to the file comment information generation method provided by the embodiments of the invention, the synchronous playing of the audio explanation and comment information can be realized, and the method is simple to realize and convenient to use.

Description

technical field [0001] The invention relates to the technical field of information processing, in particular to a method for generating document annotation information. Background technique [0002] In the process of daily office work, education and teaching, it is often necessary to annotate electronic documents (word, PPT, etc.) and share them with others. Especially when the teacher is teaching, he needs to explain the topic to the students. Therefore, it is necessary to add the annotation information and the audio of the explanation to the prepared electronic version of the courseware, and show the annotated courseware to the students. [0003] In the prior art, if you want to add annotation information to the electronic version of the courseware, you can only rely on the annotation function that comes with the software. The implementation method is relatively simple, it is not flexible enough to use, and it is impossible to realize the synchronous playback of audio expl...
