[0052] In the first embodiment of the present invention, a method for transmitting data, such as figure 1 shown, including the following specific steps:

[0053] In step S101, the server divides the multimedia service data into stream data segment files, and generates a stream data description file at the same time.

[0054] Specifically, the server evenly divides the multimedia service data into stream data segment files according to the playing duration or capacity. Each stream data segment file includes: a data segment storing playback control information, a video segment storing video data and / or an audio segment storing audio data. The stream data description file includes the initial stream data fragment file address of the multimedia service data. The playback control information includes: the playback duration of the streaming data segment file and the address of the next streaming data segment file.

[0055] Step S102, when a user download request is generated, the...

Abstract

The invention discloses a method and system for transmitting data. The method comprises: a server divides multimedia service data into stream data segment files, and simultaneously generates a stream data description file; The stream data description file is downloaded from the server, and the stream data segment file is downloaded and played based on the stream data description file. The invention can realize real-time or near real-time transmission of streaming multimedia service data, and has low cost and simple operation. The invention supports live streaming and non-live streaming multimedia service data, and the same streaming multimedia service data can also provide different code rates, which facilitates flexible combination of streaming multimedia service data providers according to requirements. In addition, since it can be used on non-real-time transport protocols, the scope of application is not restricted by firewalls.

Description

technical field [0001] The present invention relates to the technical field of data transmission, in particular to a data transmission method and system. Background technique [0002] With the development of multimedia technology, more and more clients receive and play real-time streams through the network. A common implementation method is to use streaming media technology or multimedia broadcasting technology based on RTSP (Real Time Streaming Protocol, real-time streaming protocol). In order to realize the transmission of real-time streaming data services, it is necessary to use a dedicated streaming media server. Due to the complexity of traditional streaming media technology, in order to support concurrent access by a large number of clients, it is necessary to deploy a professional streaming media server, but the cost of deploying streaming media services is huge. Therefore, streaming multimedia service providers urgently need a lower cost and simpler method for trans...
