Abstract

The embodiment of the invention provides a streaming media transmission method, device and system, user equipment and a server and relates to the technical field of communications, the method comprises the following steps: the UE receives USD information of the first media file and an MPD file, wherein the USD information comprises a distribution mode element, the distribution mode element comprises indication information, and the indication information is used for indicating a first media stream file of the first media file or a media content fragment of the first media stream file sent in aunicast mode; when the UE is in the MBMS service area, obtaining media content fragments of a second media stream file in a broadcast mode according to the USD information; and when the UE is not in the MBMS service area, obtaining the media content fragment of the first media stream file from a specified server in a unicast mode according to the indication information. According to the invention,seamless switching of streaming media from broadcast to unicast can be realized.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a streaming media transmission method and system, user equipment and server. Background technique [0002] With the continuous development of information technology, streaming media service traffic will occupy an increasing proportion in the network, and streaming media transmission technology has become the focus of people's increasing attention. Hypertext transfer protocol (Hypertext transfer protocol, referred to as HTTP) dynamic adaptive streaming media (Dynamic Adaptive Streaming over HTTP, referred to as DASH), is a streaming media transmission technology based on HTTP, the technology can dynamically adapt to changes in wireless channels and has the deployment The advantages of being simple and not affected by firewalls are expected to become the mainstream streaming media transmission technology of the next generation. [0003] The DASH technology is mainly ...
