Then, index file is obtained and with resolution unit 110, the index file that it obtains is parsed, to obtain this index
The particular content of file, for example, obtain the particular content in above-mentioned timestamp and index information.
Wherein, index information includes corresponding audio file name and/or image file name.In one example,
When index information includes audio file name, it can also optionally include this audio file name corresponding audio frequency literary composition
One or more of information such as part size, recording time and audio frequency duration；And work as index information and include corresponding image literary composition
During part title, it can also optionally include one or more information such as this image file name corresponding image size.
Then, audio frequency and/or image acquisition unit 120 are according to cited in index information in the index file content of parsing
File name to obtain file corresponding to these titles from server, such as, the audio frequency literary composition quoted according to wherein index information
Part title and/or image file name download corresponding audio file and/or image file from server.
In addition, according to the index file of parsing, time started arranging unit 130 is configured to starting play time.
For example, time started arranging unit 130 can arrange a broadcast start time point so that current time is to beginning
Play time arrives in this period of time, and time started arranging unit 130 can download predetermined quantity or predetermined from server
The audio file of size and/or image file, for caching etc..
In one example, time started arranging unit 130 can be according to these sounds in index file content included
The size (being for example included in the index file content of parsing) of frequency file and/or image file and current speed of download are estimating
Calculate the download required time of these files, then current time is added that the moment obtained by calculated download required time is made
For above-mentioned broadcast start time point.
It should be noted that predetermined quantity or predefined size can be arranged previously according to empirical value, or by test
Mode determines, I will not elaborate.
Then, reproduction time determining unit 140 determines when commencing play out according to the timestamp comprising in index file
Between put after multiple play time.Wherein, each play time determined by reproduction time determining unit 140 is distinguished
It is associated with an audio file and/or an image file.With reference to Fig. 2, reproduction time determining unit 140 to be described
A kind of example arrangement.
As shown in Fig. 2 in this example embodiment, reproduction time determining unit 140 can include audio frequency process subelement 210 and figure
As processing subelement 220, audio frequency process subelement 210 and image procossing subelement 220 can be based respectively on setting start broadcast
Put time point to determine each play time.
Hypothesis broadcast start time point is t0, with corresponding to certain audio file name in index file content cited
Audio file D1As a example illustrating, for corresponding to other audio file names in index file content cited
The determination process of the play time of audio file may be referred to following description, will no longer repeat one by one here.
As shown in Fig. 2 audio frequency process subelement 210 can calculate audio file D first1Recording starting time ts1(example
As being included in the index file content of parsing) first recording starting time ts corresponding with respect to index file0(for example comprise
Parsing index file content in) time difference Δ t1(wherein Δ t1=ts1-ts0), then by the beginning having set
Play time t0Plus this time difference Δ t1Moment (the t of gained0+Δt1) as audio file D1Corresponding play time
TD1.
Here, the corresponding recording starting time first of index file refers to cited all audio frequency in index file content
Earliest that in the recording starting time of file name each audio file corresponding.
Similarly, with the image file D ' corresponding to certain image file name in index file content cited1For
Example illustrating, for the broadcasting of the image file corresponding to other image file names in index file content cited
The determination process of time point may be referred to following description, will no longer repeat one by one here.
As shown in Fig. 2 image procossing subelement 220 can calculate image file D ' first1Recording starting time ts '1
(being for example included in the index file content of parsing) first capture time ts corresponding with respect to index file '0(for example wrap
Be contained in the index file content of parsing) time difference Δ t2(wherein Δ t2=ts '1-ts’0), then will set
Broadcast start time point t0Plus this time difference Δ t2Moment (the t of gained0+Δt2) as image file D '1Corresponding broadcasting
Time point TD’1.
It should be noted that when only comprising audio file name (not comprising image file name) in index file,
Can only make audio frequency process subelement 210 execute alignment processing as above, and make image procossing subelement 220 not execute place
Reason.Similarly, when only comprising image file name (not comprising audio file name) in index file, image can only be made
Process subelement 220 and execute alignment processing as above, and make audio frequency process subelement 210 not execute process.
So, by the process of audio frequency process subelement 210 and image procossing subelement 220, multiple broadcastings can be obtained
Time point, and wherein each play time is all after broadcast start time point.Additionally, obtained by above process
Each play time is associated with an audio file and/or an image file respectively.For example, what above citing described broadcasts
Put time point TD1It is associated with audio file D1, and play time T of description of illustrating aboveD’1Then it is associated with image file D '1.
In addition, if if certain audio file is identical with the play time corresponding to certain image file, then this play time
It is associated with this audio file and this image file simultaneously.
By above description, obtained by being utilized respectively audio frequency process subelement 210 and image procossing subelement 220
Obtain the play time of audio file and the play time of image file, enable to realize to audio file in subsequent treatment
Relatively independent broadcasting with image file.That is, broadcasting therebetween does not interfere with each other.So, in actual treatment, such as
Fruit only needs to play audio file, then image procossing subelement 220 can be made not deal with, namely make future will not play figure
As file；Conversely, audio frequency process subelement 210 can be made not deal with the case of only needing to play image file, and make
Obtain and will not play audio file.Thereby, it is possible to come according to actual needs optionally to reduce file size to be played, so as to
Enough susceptibilitys reducing to the network bandwidth, that is, more stably can play out in the case that the network bandwidth is more unstable.
Thus, by the process of reproduction time determining unit 140, each audio file and/or each image can be obtained
Play time corresponding to file.Then, in each play time determined by reproduction time determining unit 140, play
Unit 150 plays the audio file associating with this play time and/or image file.For example, it is assumed that reproduction time determines list
Unit 140 has determined certain audio file D3Corresponding play time is moment T1, then when moment T1 arrives, broadcast unit
150 commence play out audio file D3.
Additionally, in device 100, updating block 160 termly can obtain up-to-date index file from server, with more
Newly current index file.
It should be noted that, although above example describe successively index file obtain with resolution unit 110, audio frequency and/
Or image acquisition unit 120, time started arranging unit 130, reproduction time determining unit 140, broadcast unit 150 and renewal are single
The process of unit in unit 160, but the process execution sequence of above unit is not limited to this.For example, the time started sets
Put unit 130 and reproduction time determining unit 140 synchronously can be processed with audio frequency and/or image acquisition unit 120, or
Person, time started arranging unit 130 and reproduction time determining unit 140 can also indexed file obtain and resolution unit 110
Afterwards, executed before audio frequency and/or image acquisition unit 120 process (but the process of reproduction time determining unit 140 start
Carry out after set of time unit 130), etc..
By above description, the above-mentioned broadcasting media data being used for direct-seeding according to an embodiment of the invention
Equipment, it obtains corresponding audio file and/or image file according to the index file obtaining from server from server,
The play time determining plays the audio file associating with this and/or image file respectively.With respect to such as many based on HLS
For the existing multi-medium data play-back technology such as media data play-back technology, this equipment needs to be played from server acquisition
File (can be one of audio file and image file or two kinds) less so that the susceptibility to the network bandwidth for this equipment
Relatively low, thus the susceptibility to the network bandwidth can be reduced during live that is to say, that more unstable in the network bandwidth
In the case of, can more stablize than above-mentioned existing multi-medium data play-back technology, play out glibly.
For existing mobile network's terminal, because result of broadcast when carrying out live using this equipment is more steady
Fixed, smooth, therefore this equipment is more advantageous compared to above-mentioned existing multi-medium data play-back technology.
