Video segmenting storage method and system applied to media data access

Abstract

The invention discloses a video segmenting storage method and system applied to media data access. The method comprises the steps that: S101: high-code-rate materials are loaded; S102: segmenting processing is carried out high-code-rate video and audio files / signals according to fixed time or according to groups of pictures; S103: the high-code-rate materials and low-code-rate internet video fileswith the same contents with the high-code-rate materials form a time-domain corresponding relationship; S104: every when one segment file is partitioned, information of MPD / M3U8 is updated; S105: information recorded in MPD / M3U8 files comprises segment file information of media files; and S106: in the MPD / M3U8 files, files of a high-code-rate part are separately described. The system comprises amedia data server, an internet access terminal, a file simulation service module and a professional network access terminal. The video segmenting storage method and system disclosed by the invention sufficiently accord with the characteristics of the category of media files, are beneficial for transmitting video and audio files while accessing, and improve production efficiency.

Description

technical field [0001] The present invention relates to media data storage technology, in particular to a video slice storage method and system applied to media data access. Background technique [0002] Existing media data access technologies include media data access on professional video networks and media data access on the Internet / mobile network. The media data access of the professional video network is mainly through file sharing, and the media files are obtained through the professional link. There are many media data access methods on the Internet / mobile network: connection-oriented streaming media technologies such as RTSP / RTP, connectionless HTTP progressive download, HTTP-based dynamic adaptive streaming access represented by MPEG-DASH / HLS . [0003] There are still some deficiencies in the existing media data access technologies: 1) The video and audio file storage solutions are not fully designed for video characteristics. Metadata separation, redundant fil...

AI Technical Summary

Problems solved by technology

[0003] There are still some deficiencies in existing media data access technologies: 1) The video and audio file storage scheme is not fully designed for video characteristics, and some video and audio storage is mostly based on general storage and general file systems, without considering video characteristics, such as video Metadata separation, redundant file systems, etc.

So that when accessing a file, only the entire file can be accessed, but not a part of it, which undoubtedly reduces the efficiency of access and also causes a large waste of bandwidth

Technologies such as MPEG-DASH applied to the Internet / mobile network have improved the storage and access of video and audio files, but professional video networks, as an important part of video and audio sources, cannot meet such requirements; 2) professional video networks and the Internet / Mobile network separation, does not meet the trend of converged development

[0004] The radio and television media industry mainly uses professional high-code materials in the whole process from collection to broadcasting, and these materials have a high demand for bandwidth, which cannot be supported by general network bandwidth.
