Embodiment 1

[0204] It can be known from the above embodiments that when the data source received by the BM-SC network element is a non-DASH data source, the format of the media description file included in the data source may be in MPD format or in non-MPD format. This embodiment is mainly described for the case that the format of the media description file is not in the MPD format.

[0205] Step S2514, after the terminal receives the SA file sent by the BM-SC network element from the public channel broadcast, it parses the content of the media description file corresponding to the program to be played in the terminal from the received SA file (same as the above-mentioned content of the third media description file), and at the same time obtain the channel access method corresponding to the program to be played.

[0206] In step S2516, the terminal accesses the channel through the channel access method acquired in step S2514, and receives the media segment file corresponding to the ...

Embodiment 2

[0209] This embodiment mainly describes the situation when the format of the media description file is the MPD format.

[0210] Step S2528, the terminal receives the SA file sent by the BM-SC network element from the public channel broadcast and receives the media segment file through the channel information corresponding to the content of the third media description file recorded in the SA file (the step S2528 is the same as the above-mentioned Step S2514 and Step S2516);

[0211] Step S2530, the terminal judges whether the format of the media segment file includes the format of the media segment defined in the DASH protocol, if the judgment result is that the format of the media segment file does not include the format of the media segment defined in the DASH protocol , go to step S2532, otherwise go to step S2536;

[0212] Step S2532, after determining that the format of the media segment file does not include the format of the media segment defined in the DASH pro...

Abstract

The present invention provides a stream media transmission method, playback method, transmission device and playback device, comprising: receiving a data source to be transmitted in a multimedia broadcast multicast service MBMS system, wherein the data source to be transmitted includes: the first A media description file and corresponding media fragmentation file, this first media description file is used to describe the stream media data characteristic of media fragmentation file; If the data source to be transmitted is the non-dynamic adaptive streaming media DASH data source, then will The format of the first media description file is converted into the MPD format of the media presentation description to obtain the second media description file; and the content and media segment files in the second media description file are broadcasted. It solves the problem that the non-DASH data source cannot be sent to the terminal in the MBMS system existing in the related art.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a stream media transmission method, a playback method, a transmission device and a playback device. Background technique [0002] There are many ways of streaming media transmission based on hypertext transfer protocol (HyperText Transfer Protocol, referred to as HTTP) adaptive streaming transmission, the following dynamic adaptive streaming media (Dynamic Adaptive Streaming over HTTP, referred to as DASH) and real-time streaming (HTTP Live Streaming, referred to as HLS) as an example for illustration. [0003] Both DASH and HLS are currently mainstream streaming media transmission methods based on HTTP adaptive streaming transmission. They are characterized by continuously sending media fragment files in HTTP mode to achieve media data transmission. Among them, HLS was launched by Apple in 2009, and DASH It was launched in 2011 by the Moving Picture Experts Group (MPEG for sh...
