Embodiment one
Fig. 1 is the method flow schematic diagram of a kind of transmission audio-video and message that the embodiment of the present invention one provides.This implementation
Example be applicable to include terminal and server the network architecture.Wherein, the terminal is to play to need with audio-video and message
The iOS device asked, for example, IPhone, Ipad, Itouch or Mac, the equipment are usually held by audio-video viewing side；Institute
Stating server is that the physical equipment of audio-video service is provided for terminal.Method provided in this embodiment can be by the above-mentioned network architecture
In server execute.Referring to Fig. 1, the method for transmission audio-video and message provided in this embodiment specifically comprises the following steps
S110-S130。
Step S110, it obtains and M3U8 index corresponding to multiple slice files that cutting obtains is carried out to current audio/video flow
File.
Wherein, M3U8 index file include it is multiple slice files information (including：Duration information and resource address information).
The duration information of any one slice file, for describing the playing duration of the slice file when playing out；Resource address
Information is used to describe the storage path of the slice file on the server, usually URL (Uniform Resource
Locator, uniform resource locator).In M3U8 index file, the duration information of any one slice file is recorded in " #
EXTINF:" at position between label and " comma ", " comma " is a newline below, later immediately following the resource of slice file
Address information.
For example, the partial content of the M3U8 index file of an audio/video flow based on HLS protocol can be described as：
#EXTM3U
#EXT-X-MEDIA-SEQUENCE:6
#EXT-X-TARGETDURATION:10
#EXTINF:3.1,
http://live.example.com/1.ts
#EXTINF:4.2,
http://live.example.com/2.ts
#EXTINF:5,
http://live.example.com/3.ts
It in this example embodiment, altogether include the duration information and resource address information of three slice files.Each slice file
Information is with " #EXTINF:" label conduct beginning identifier.These three slice files duration informations be respectively：3.1,4.2
With 5, resource address information is respectively：http://live.example.com/1.ts,http://live.example.com/
2.ts and http://live.example.com/3.ts.
Step S120, it will be used to describe the content of message associated by slice file, M3U8 index file be added to, with life
The M3U8 index file of Cheng Xin.
It step S130, will be under new M3U8 index file after receiving terminal to the watching request of current audio/video flow
Issue terminal.
Terminal, can be according to new M3U8 index file from server before playing and being associated with the target slice file of message
Get the message of target slice file association.
To meet user's particular demands, it will usually corresponding by file association is sliced some or all of in current audio/video flow
Message.For example, to promote the viewing experience of user, it can be to some slices for the audio/video flow that speech scene is recorded
File is associated with the message such as the speech draft of vote interface or PPT format so that terminal play be sliced file while, together
Step plays to message associated by user and the slice file.However, traditional HLS protocol be only applicable to M3U8 index file with
It is sliced the transmission of file, does not support the transmission of other any kind of message datas.So the usual way of the prior art is to adopt
With other transmission modes, terminal will be handed down to message associated by slice file.Due to the conveyer of message and audio/video flow
System is different, so easily leading to the generation of following phenomenon：Terminal does not receive what server issued also when playing slice file
With the message of the slice file association.
In view of this, the present embodiment improves traditional HLS protocol, so that the agreement is in transmission audio-video fluxion
According to while, also in synchronous transfer and the associated message data of audio/video flow.Specific way is to modify traditional audio/video flow
M3U8 index file, associated message is carried in the M3U8 index file.
Preferably, it will be used to describe the content of message associated by slice file, be added to M3U8 index file, to generate
New M3U8 index file, including：
It will be used to describe the content of message associated by slice file, be added at the following position of M3U8 index file：
It is sliced behind the duration information of file, before resource address information.
In the present embodiment, the content for describing message associated by slice file can be message itself, Huo Zhewei
The character string of message repository location for identification.If message capacity is very big, the content is preferably used for identification message and deposits
The character string that storage space is set.On the contrary, if message capacity is smaller, the content is preferably message itself, because can make in this way
Terminal is obtained when getting the M3U8 index file after addition operation, message is directly obtained, without passing through identifier again
Server is accessed to obtain message.
Specifically, can will be used to describe the slice for the information of a slice file in M3U8 index file
The content of the message of file association is added in " #EXTINF:" at " comma " subsequent position after label, and with newline
End identifier as the content.In this way, the corresponding character string in next line position is the resource address letter of the slice file
Breath.
For example, in original M3U8 index file, the information of some slice file is：
#EXTINF:3.1,
http://live.example.com/1.ts
If the message of the slice file association is following character string：
[{“json”:{“time”:44.65,“name”:“flipover”,“type”:“event”,“parameters”:
{“file”:23 534.00,“page”:1.00}},“time”:4.1}]
Then, in the new M3U8 index file of generation, the information update of the slice file is：
#EXTINF:3.1,[{“json”:{“time”:44.65,“name”:“flipover”,“type”:“event”,
“par ameters”:{“file”:23534.00,“page”:1.00}},“time”:4.1}]
http://live.example.com/1.ts
The addition manner that above-mentioned preferable example provides, is advantageous in that：Without making larger improvement to terminal, solved in terminal
Analyse one slice file information when, as long as read behind the duration information of the slice file with the word before resource address information
Symbol string, is the content for describing message associated by the slice file；Also, even if not making corresponding improvement to terminal,
Terminal will not report an error when parsing new M3U8 index file, only can obtain and play slice file.
Certainly, it should be appreciated by those skilled in the art that also M3U8 index file can be made to take by other addition manners
With associated message.For example, by be used to describe message content add behind resource address information, using newline as
End identifier, and separated between message and resource address information with preset unique identifier (for example, comma).Terminal exists
After obtaining new M3U8 index file, when carrying out the information parsing of a slice file, as long as identifying unique identifier, read
The character string behind the identifier before newline is taken, is the content for describing message associated by the slice file.
Alternatively, associated message is not implanted into the information of each slice file of M3U8 index file, but it is independent
A mapping table is created, which is stored in M3U8 index file in the form of character string.The mapping table is for describing
Incidence relation between the resource address information of each slice file and the content for describing each message.Terminal is obtaining newly
M3U8 index file after, by reading mapping table, obtain message with this slice file association to be played.
Technical solution provided in this embodiment, improves traditional HLS protocol, and message is added to audio/video flow
M3U8 index file in, allow server to be based on HTTP for message and audio/video flow synchronous transfer to terminal, Jin Erke
With guarantee message with its associated by audio-video slice file be played simultaneously.
Based on the above technical solution, the content for describing message associated by slice file is message itself；
Message be binary form message or for include newline character string forms message；
In the content that will be used to describe message associated by slice file, it is added to before M3U8 index file, further includes：
Message is encoded using preset coding mode, to convert the message to not include the character string for having newline
The message of form.
Preferably, preset coding mode is base64 coding.
