Specific embodiment
To keep the technical problem to be solved in the present invention, technical solution and advantage clearer, below in conjunction with attached drawing and tool
Body embodiment is described in detail.
In order to supply that easy reference is described in greater detail below, it should be noted that tradition is as shown in Figure 1, existing eMBMS system
System structure mainly includes content input (content source, DASH encoder), BM-SC11 broadcasting service platform, LTE network and terminal 12
(middleware supports the encapsulation to eMBMS broadcast-capable, using APP).
For content providers: existing eMBMS system needs to invest DASH encoder again, and carries out to all the elements source
It transcoding and stores again.
For APP developer: need newly-increased DASH processing module, be responsible for MPD (MPD is a kind of video format) parsing and
The processing of media slicing, including dynamic code rate adaptation.
The present invention DASH standard single for the end-to-end product support of eMBMS current in the prior art, while cannot
The problem of more preferably realizing the conversion and intercommunication between DASH and HLS, causing the wasting of resources, provides a kind of adaptive stream media skill
Conversion method, device, BM-SC and the terminal of art increase an index file conversion newly on BM-SC broadcasting service platform and carry out
Conversion between M3U8 (M3U8 is a kind of " video format ") and MPD, and select to support same media slicing format；In terminal side
Middleware and video APP between increase an index file inverse transform, the MPD received can be converted into M3U8, in this way
It can be multiplexed existing encoder device, also do not need to carry out transcoding and additional storage again to existing film source, while can also
It is multiplexed the end-to-end equipment of existing eMBMS (including chip, terminal and BM-SC platform etc.)；Operator is realized to broadcast energy
The standardized packages of power not only promote industrial chain using LTE MBMS broadcast-capable and provide business, but also promote LTE
The scale development of MBMS business lays the foundation.
As shown in figure 3, adaptive stream media technology of the embodiment of the present invention for broadcast multicast service center BM-SC
Conversion method include:
Step 301, the code stream input data for obtaining hypertext transfer protocol live streaming media HLS, wherein the code of the HLS
Input data is flowed in HLS encoder, and the code stream input data branch with dynamic self-adapting hypertext transfer protocol stream DASH
Hold same media slicing format；
Step 302, the code stream input data of the HLS is converted to the code stream input data of the DASH；
Step 303, the code stream input data of the DASH is sent to terminal.
As shown in figure 4, the conversion method of adaptive stream media technology of the embodiment of the present invention for terminal includes:
Step 401, the code stream input data for receiving dynamic self-adapting hypertext transfer protocol stream DASH, wherein the DASH
Code stream input data come from broadcast multicast service center BM-SC, and the code stream with hypertext transfer protocol live streaming media HLS

Step 402, the code stream input data of the DASH is converted to the code stream input data of HLS；
Step 403, streaming media playing is carried out according to the code stream input data of the HLS.
Briefly it is exactly after being contacted terminal and the foundation of BM-SC broadcasting service platform by network, then by the code stream of HLS
The code stream input data that input data is converted to DASH is sent to terminal, and then terminal is then converted to the code stream input data of HLS
It plays out.
Specifically, BM-SC broadcasting service platform is got the HLS's in HLS encoder (data from content source)
Code stream input data (step 301), and after being converted to the code stream input data (step 302) of DASH, last BM-SC broadcasting service
Platform is then forwarded to terminal and carries out streaming media playing (step 303), next, terminal is in the code stream input data for receiving DASH
After (step 401), code stream input data (being the application format in order to adapt to terminal) (step 402) of HLS is converted to, it is last whole
End carries out streaming media playing (step 403) according to the code stream input data of HLS.Can be multiplexed so existing encoder device,
It does not need to carry out transcoding and additional storage again to existing film source, while the end-to-end equipment of existing eMBMS can also be multiplexed yet
(including chip, terminal and BM-SC platform etc.)；Operator is realized to the standardized packages of broadcast-capable, is not only promoted
Industrial chain provides business using LTE MBMS broadcast-capable, and the scale development for promoting LTE MBMS business lays the foundation.
It should be noted that: DASH and HLS determines two aspects as adaptive stream media technology, agreement
Justice: index file format and media slicing data format.
In terms of indexed file format, HLS defines M3U8 file to describe the constituent relation of each media slicing, and DASH is then
MPD is introduced to be described.Tool is very different between the two data structure.
As shown in Fig. 2, HLS only supports MPEG-2 TS, DASH then to support following four in terms of media slicing data format
Kind frame profile.These profile are more and complicated, need not all realize in practical application, may be selected to support one of.
Wherein MPEG-2 TS Main Profile (Moving Picture Experts Group Transport Stream Main
Profile, the main frame of dynamic image expert group transport stream) file format requirements that HLS is supported are corresponded to completely, selection is supported
MPEG-2 TS Main Profile can be multiplexed current HLS encoder and multiplexing has a large amount of film sources, without transcoding and
Store multiple backups.
Since DASH and the HLS file format supported not are that can all share, the embodiment of the present invention for
In the conversion method of adaptive stream media technology for broadcast multicast service center BM-SC, the media slicing format is
The main frame MPEG-2 TS Main Profile media slicing format of state picture experts group transport stream.

List；
Step 3023, the index file format of the HLS is converted to the DASH's according to the transformational relation list
Index file format.
In order to facilitate realization, by increasing the conversion (step 3023) of index file format newly, and select to support MPEG-2 TS
Main Profile media slicing format can then input the code stream that the code stream input suitable for HLS is converted to suitable DASH,
To not only be multiplexed existing encoder and film source, but also existing eMBMS facility can be multiplexed.
In the conversion method of adaptive stream media technology of the embodiment of the present invention for terminal, step 402 includes:
Step 4021, the index file format of the DASH is obtained；

Series of tables；
Step 4023, the index file format of the DASH is converted to by the HLS according to the inverse transform relation list
Index file format.
By increasing the conversion (step 4023) of index file format newly, and select to support MPEG-2 TS Main Profile
Media slicing format can then input the code stream that the code stream input suitable for HLS is converted to suitable DASH, to both be multiplexed existing
There are encoder and film source, and existing eMBMS facility can be multiplexed.It should be noted that above-mentioned HLS and DASH index file format
Mutual transformational relation list such as table 1:
In order to transmit the code stream input data of the DASH after BM-SC conversion, the embodiment of the present invention is for broadcast group broadcast
In the conversion method of adaptive stream media technology for service center BM-SC, step 303 includes:
Step 3031, number is inputted by the code stream that timesharing long-term evolving network TD-LTE Nentwork sends the DASH
According to the terminal.
In the conversion method of adaptive stream media technology of the embodiment of the present invention for terminal, step 401 packet
