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
DASH and other technologies applied on 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 Internet / mobile Network separation does not meet the trend of converged development

Embodiment 1
[0042] Such as figure 1 As shown, a high-code file media data access system includes: a media data server and a professional network access client; the professional network access client is connected to the media data server;
[0043] The professional network access client includes: client control module, MPD / M3U8 analysis module, slice analysis module, SDK access module and player;
[0044] The client control module is used to control video playback;
[0045] The MPD / M3U8 parsing module is used for parsing MPD / M3U8 files to obtain information about media files and sliced files thereof;
[0046] The slice parsing module is used for parsing the received slice file;
[0047] The SDK access module is used to send an access request to the media data server through the SDK;
[0048] The player is used to play the parsed slice file;
[0049] The professional network access client is used for accessing the parsed slice files.
[0050] Such as figure 2 As shown, a high-code f...

The invention discloses a high-code file media data access method and system. The method includes: S1: establishing a connection; S2: acquiring the MPD / M3U8 file; S3: parsing the MPD / M3U8 file; S4: accessing the file by a professional network access client. The system includes a media data server and a professional network access client, and the professional network access client is connected with the media data server. The invention improves the access efficiency of high-code file media data, each slice is a relatively independent individual, the analysis of slices does not need the assistance of other slices, and a slice can be accessed after it is formed, realizing simultaneous acquisition, simultaneous return, and simultaneous The accessed media data access mode improves production efficiency and meets the development trend of professional video network and Internet / mobile network integration.
Description
technical field [0001] The invention relates to media data access technology, in particular to a high-code file media data access method and system. Background technique [0002] Existing media data access technologies include media data access for professional video networks and media data access for Internet / mobile networks. The media data access of the professional video network is mainly through file sharing, and media files are obtained through professional links. The format of the files is mainly broadcast and television professional video and audio formats, such as: .mxf, .avi, etc. 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, and HTTP-based dynamic adaptive streaming access represented by DASH / HLS. [0003] There are still some deficiencies in existing media data access technologies: 1) The video and audio file storage scheme is no...
