Problems solved by technology

[0005] However, the prior art multimedia uses time to record audio-visual video sequences. Generally, users tend to be confused about similar time-series records, and cannot remember in detail when the audio-visual clips appear.
Therefore, the search method of the prior art relies solely on memory and blind carpet-like search methods. For audio-visual files with larger and larger capacities, searching for target audio-visual clips is like finding a needle in a haystack. method is not efficient
Although there are other prior technologies that search by comparison methods such as graphics and sound waves, the process is too complicated and inconvenient to use
Therefore, there are still problems to be solved urgently in the search efficiency of the search method for multimedia content in the prior art

Embodiment Construction

[0033] In order to achieve the above object, the present invention adopts the technical means and its effects, hereby give preferred embodiments, and illustrate as follows in conjunction with the accompanying drawings.

[0034] Although the general user's memory is easy to confuse the time when the desired video clip appears, but the sound and dialogue appearing in the special screen will be deeply remembered. Therefore, the multimedia content searching method of the present invention mainly forms the subtitles of the multimedia in a retrievable manner, allowing users to use the dialogue strings that are easier to recall as a method for searching for the desired video and audio segments in the multimedia content.

[0035] Generally, multimedia content stores subtitles and audio, video and video files separately. Take DVD multimedia files as an example, please refer to figure 2 , for the file content of the DVD multimedia. DVD multimedia generally includes two folders, inclu...

Abstract

The invention relates to a method for searching multimedia contents, which comprises the following steps: firstly, retrieving subtitle information of a multimedia file; secondly, identifying subtitle pictures of the subtitle information to form a searchable character subtitle fragments; forming a subtitle index file with the character subtitle fragments and the occurrence time thereof; retrieving a subtitle fragment list containing a keyword string; playing and inspecting multimedia when the multimedia skips to the occurrence time of the subtitle fragments in the list; and when a target audio-visual fragment is not searched, typing in other keyword strings to retrieve again, and searching the target audio-visual fragment to improve the searching efficiency.

Description

technical field [0001] The present invention relates to a method for searching video and audio clips, in particular to multimedia with subtitles, using keyword strings to quickly search for required video and audio clips in multimedia content. Background technique [0002] With the advancement of multimedia technology, the era of high-definition audio-visual has come. The audio-visual multimedia will rapidly increase from 4.7GB DVD audio-visual multimedia to 25GB (single-layer), or even 50GB (double-layer) BD (Blu-ray) multimedia. As the data becomes larger and larger, a faster search method is needed to efficiently find the required video and audio clips in the multimedia. [0003] Such as figure 1 Shown is the flow of the search method for multimedia content in the prior art. Because the audio-visual file of multimedia in the prior art utilizes time to record audio-visual video sequences, and the audio-visual video is divided into several sections of scene paragraphs to ...
