Method and device for realizing mutual positioning and character fast recording of video data and text data

Abstract

The embodiment of the invention provides a method and device for realizing mutual positioning and character fast recording of video data and text data. A method for positioning text data by use of video data comprises the following steps of: inputting the video data, text data associated with the video data and the time label information, wherein the time label information includes the corresponding relationship between the paragraph value of the text data and the relative time length, and the relative time length is the time length from the start time point of the video data to the time label generation time point; in the playing process of the video data, obtaining the video relative time value after the positioning according to the positioning operation of a user on the video data; searching the time label information for the relative time length proximal to the video relative time value and the paragraph value corresponding to the proximal relative time length; and positioning the text data to the paragraph corresponding to the searched paragraph value according to the searched paragraph value. The method can position the text data by use of the video data.

Description

technical field [0001] The invention relates to a field of interaction between text and video data in a video and text recording system, in particular to a method and device for mutual positioning of video data and text data, and a method and device for quickly entering text. Background technique [0002] Video and text recording is a relatively new industry. It is often used for court clerks to record video transcripts and interrogation records in the interrogation room of the Public Security Procuratorate. high expectation. Therefore, in application industries such as public security, procuratorate, and law that cannot be equipped with stenographers, it is difficult to enter electronic transcripts through information equipment. [0003] Video recording is to convert and compress analog signals into digital signals through image acquisition equipment, and then record video information through streaming media network transmission or hard disk video recorders.

AI Technical Summary

Problems solved by technology

However, in the current recording system, video and text are relatively separated, and there is no correlation. After recording, it is impossible to conveniently modify the text content according to the video and audio to achieve the proofreading effect.

[0006] In addition, the inventor also found in the process of realizing the present invention that video and text in the prior art cannot effectively interact, and a method of using video data to control text data and using text data to control video data is needed. means
