Embodiment Construction

[0053] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0054] The core idea of ​​the present invention is to divide the file into pages, and each page is an independent media structure (the media structure can be a standard format such as MP4 / TS / AMR / AAC, or a self-defined private format). The paging can be nested to include some access units and sub-access units (access units and sub-access units are also independent media structures, which can be called Clips), thereby improving the real-time performance of storage and reading. The media structure refers to an independent unit that can be played after being cut, such as a small MP4 file, a section of TS file, or a custom format file segment that can be streamed on demand. Each page and access unit (including sub-access units) may adopt a unified media format, or may adopt different media formats.

Abstract

The invention relates to the technical field of multimedia, in particular to a method and a device for storing and broadcasting multimedia information. The invention provides a method for storing the multimedia information, which comprises the following steps: A, multimedia documents including at least one independent paging are established or opened by preset document names, the multimedia documents include format description information of the multimedia documents, and the format description information includes conversational description agreement information and paging information; and B, the data of multimedia information to be stored is stored in each paging of the multimedia documents according to the format description information, and each paging of the multimedia documents is divided into more than one independent access unit and used for loading and storing a data packet of the paging of the multimedia documents. The invention can not only realize the real-time zero access of the multimedia information within several seconds, but also solve the problem that the access efficiency is low due to small data access and massive adaptation; and meanwhile, the data is convenient for division and mergence and compatible standard format.

Description

technical field [0001] The invention relates to the field of multimedia technology, in particular to a method and device for storing and playing multimedia information. Background technique [0002] At present, in the process of streaming real-time images, it is generally necessary to store the images for later playback. But according to the practice of most of this field at present, all is to adopt camera equipment, the live image is converted into file formats such as MP4 for playing in the future. However, for the current increasing demand for time-shifting services, this method of storage and dumping is too slow because it takes a long time to construct a complete MP4 file, and it is completely unsuitable for the demand for programs after a few seconds. [0003] In the prior art, a segmented or segmented storage is also proposed to improve the efficiency of locating the playback position. However, fragmented storage also has the disadvantages of reading and writing mor...
