Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] The segmented storage format of streaming media files is as follows: figure 1 As shown in , it is divided into two parts: the global index and the fragment file, and the two parts are associated through the directory (the name of the fragment file). The global index file part contains the basic description information (SDP information) of the requested storage medium and the index information of each fragment file (such as figure 2 shown); the fragmented file part is mainly used to store the multimedia information of each specific data packet, and also includes the index information of each media data packet (such as image 3 shown). The index information of the fragment file is stored in the global index file, and its purpose is to locate which fragment the specific data packet is located in; the index information of the da...

Abstract

The invention discloses a method for real-time storing and playing multimedia image information. The method for storing includes the following steps: (a) a slicing base directory is established according to names of stored files, and a global index file is established in the slicing base directory; information of a session description protocol in a multimedia file and index information of a slicing file are stored in the global index file, the session description protocol is called as SDP information for short hereinafter; (b)according to the regulation recorded in the index information of the slicing file in the global index file, a directory of the slicing file is established; and (c) the slicing file is established under the directory of the slicing file, and the slicing file includes the index information of each media data packet and the content of each data packet. The method for playing utilizes the global index and a slicing index to position the data packet so as to carry out the operation of playing. By adopting the method in the invention, the storage of file has simple format with small difficulty for implementation, and the cost of the storage device is saved; meanwhile, the experience and feeling of users on the media program is improved.

Description

technical field [0001] The invention relates to a method for storing and replaying real-time multimedia image information during live broadcasting. Background technique [0002] At present, in the process of streaming real-time images, it is generally necessary to store the images for later playback. However, according to the current practice of most industries, camera equipment is used to convert live images into file formats such as MP4 for later playback. In some patents, segmented storage is also proposed to improve the positioning of playback positions. However, for the current time-shift service needs to be supported, this method of storage and dumping is completely unsuitable for the demand for programs after a few seconds because the storage speed is too slow and it takes a long time to construct a complete Mp4 file. Therefore, a new storage format needs to be proposed to meet the requirements for file storage of multimedia images. At present, there is no storage f...
