Embodiment Construction

[0012] Aiming at the technical problems raised by the background technology, the present invention provides a solution for transferring multimedia audio and video files. The solution for transferring multimedia audio and video files continuously stores multimedia audio and video files on a block storage device according to their media time. When it is necessary to query the video at a certain time later, the system can quickly locate the video and play it automatically. The scheme of the present invention is described in detail below through specific examples.

[0013] The multimedia audio and video files in this embodiment include but are not limited to files in MP4, WMV, and MR formats. The following uses the MP4 format file as an example for illustration.

[0014] Currently, several MP4 files need to be stored in a manner suitable for one-click retrieval.

[0015] First, these several MP4 files are sorted in chronological order. The system first obtains the media start ...

Abstract

The invention provides an audio and video file storage and retrieval method. The method comprises steps of sorting audio and video files to be stored according to the time order, and sequentially storing the sorted files to be stored based on block formats. The storage of each file to be stored based on the block formats comprises steps of developing block format storage zones on a storage device; filling in super-block zones with corresponding super-block information; filling in first-stage index zones with first-stage time indexes; filling in second-stage time index zones of data units with second-stage time indexes; and filling in data zones of the data units with I-frame group data. By employing the audio and video file direct storage method, a user can watch all the videos in a one-click manner just by inputting time periods of the videos to be watched in a direct storage system.

Description

technical field [0001] The invention relates to the field of storage and retrieval of video files, in particular to a method for transferring and retrieving audio and video files. Background technique [0002] At present, there are many program files stored in file formats such as MP4, WMV, RM, etc. When it is necessary to watch the video content of a certain absolute time period, the operation is very complicated. Take the MP4 file as an example, you first need to find out which MP4 video files the video to be watched is distributed in, then open the MP4 file, drag the playback position to the time to be watched on the OSD, and then watch it. For example, when watching a TV program from 14:00 to 14:20 on December 1, 2014, you first need to determine which video files the TV program is distributed in, and then drag it to the video screen to display the time as 14 :00 position to start viewing. When it is necessary to watch the time period discontinuously, it is necessary t...
