Embodiment 1

[0046] This embodiment provides a streaming media file storage method, such as figure 1 shown, including:

[0047] 101. Divide the media file into at least one sub-media file, where each sub-media file includes a header data segment and a TS data segment.

[0048] Specifically, the header data segment includes: a self information segment, a media information segment, and a frame information segment, the self information segment stores a media file identification number ID, and the media information segment stores a time parameter of a sub-media file, The frame rate of the media file, the frame information section stores the key frame index table and the frame index table of the sub-media file; the TS data section stores the TS stream data corresponding to the header data section.

[0049] 102. Store all sub-media files of the media file.

[0050] The execution subject of this embodiment may be a streaming media file storage device, such as a storage server.

[0051] The med...

Embodiment 2

[0079] Embodiments of the present invention provide a streaming media file storage method, such as figure 1 shown, including:

[0080] 101. Divide the media file into at least one sub-media file, where each sub-media file includes a header data segment and a TS data segment.

[0081] When dividing the media file, when the frame number is greater than the frame index table of the sub-media file or the frame number of the key frame is greater than the length of the key frame index table of the sub-media file, the media file must be divided. When setting the length of key frame index table and frame index table, you can adjust the ratio of key frame index table and frame index table to achieve the most effective space utilization rate. After setting, the length of key frame index table and frame index table will be determined. For specific division examples, please refer to the following Figure 9 section description.

[0082] Of course, when the frame number is less than the ...

Embodiment 3

[0112] This embodiment provides a streaming media file playback method, please refer to Figure 10 ,include:

[0113] 11. Receive a connection establishment request sent by the client, where the connection establishment request carries a file ID to which the client wants to establish a connection.

[0114] 12. Search for a media file corresponding to the file ID, where the media file is divided into at least one sub-media file.

[0115] 13. After finding the media file corresponding to the file ID, send a reply message to the client, the reply message carrying the video type, audio type, and DRM mark of the media file.

[0116] 14. Receive the play instruction sent by the client, where the start time point is carried in the play instruction.

[0117] 15. Comparing the starting time point selected by the client with the time parameters of all sub-media files of the media file, and determining the target sub-media file, the target sub-media file contains the starting point sel...

Abstract

The embodiment of the invention discloses a storage and playing method, device and system of a streaming media file, which can improve the reading efficiency of a media file. The storage method of the streaming media file comprises the following steps of: dividing the media file into at least one media subfile, wherein each media subfile comprises a head data section and a TS (Transport Stream) data section; the head data section comprises a self information section, a media information section and a frame information section; the self information section stores a media file identification (ID); the media information section stores the time parameter of the media subfile and the frame rate of the media file; the frame information section stores a key frame index table and a frame index table of the media subfile; the TS data section stores TS stream data corresponding to the head data section; and storing all the media subfiles of the media file. The embodiment of the invention is mainly applied to a system for supporting the storage and playing of the streaming media file.

Description

technical field [0001] The invention relates to the field of multimedia, in particular to a method, device and system for storing and playing streaming media files. Background technique [0002] As network infrastructure improves, display technology evolves. High-quality programs such as high-definition TV, high-definition movies, and 3D movies have been able to enter ordinary families. In the application of Internet video and Internet Protocol Television (IPTV), such high-quality program video on demand (Video on demand, VOD) services will occupy a large proportion. [0003] Most of the existing technologies are based on file formats such as MP4 and 3GP, store them in slices, and build key frame indexes in private segments based on files such as MP4 and 3GP. This method solves some problems such as storage and redundancy, but increases the complexity of streaming media implementation. The streaming media server needs to parse file formats such as MP4 and 3GP, and read me...
