Specific embodiment
With reference to the accompanying drawing, further description of the specific embodiments of the present invention.Following embodiment is only used for more
Technical solution of the present invention is clearly demonstrated, and not intended to limit the protection scope of the present invention.
Fig. 1 shows the data cached flow diagram for sending processing method of one kind provided in this embodiment, such as Fig. 1 institute
Show, data cached transmission processing method provided in this embodiment includes following treatment process:
S101, when server receives the reception message of client transmission, using the first scheduled rate to the client
Send the data cached of the server；
Wherein, the message that receives is the message that the client receives multicast sequence number；
First scheduled rate receives the rate of multicast data flow lower than the server.
In the present embodiment, the server refers to fast channel switching server namely FCC (Fast Channel
Change) server.The client refers to video playing terminal, also referred to as terminal player.
In the present embodiment, the data cached application back for sending processing method provided in an embodiment of the present invention under introducing first
Scape: the live broadcast service of internet television (IPTV, Internet Protocol Television) is different from traditional broadcast business,
It is to be decoded as the multicast group where video playing terminal is firstly added channel code stream, then to received multicast channel code stream.
That is, different from traditional broadcasting and TV live streaming, the live streaming IP-based multicast pattern of IPTV service is carried out.In the live streaming of IPTV service
In, the video flowing that content and service provider is provided is based on TS (Transport Stream) format more and is transmitted, to ensure to regard
Frequency stream orderly can be distributed to client, need to be packaged by RTP (Reliable Transport Protocol),
Then it pushes again and is distributed to client.Simultaneously as the video coding algorithm that IPTV is used, the channel code stream of live streaming is encoded as
The image sequence being made of I frame, P frame and B frame, as shown in Fig. 2, I frame is usually that (Group of Pictures is drawn each GOP
Face group) first frame, as the reference point of random access, image, I frame one can be indirectly displayed as by moderately compressing
As compression efficiency it is minimum and volume is maximum, B frame and P frame need correctly to be parsed and be shown based on sagittal frame, press
Contracting efficiency is big and volume is small with respect to I frame, and the GOP of typical TS is as shown in Figure 2.For between video quality and transmission volume size
The GOP of balance, the TS stream that content service provider provides is generally 2 seconds.When client receives rtp streaming, the first frame received may be
Any frame of two I frame (key frame) compartments, if the I frame that client receives first, due to the characteristic of I frame, client can be with
Directly display and show picture, if what client first received is P frame and B frame, the characteristics of due to P, B frame, before needing to rely on to I frame
Preamble frame between to this frame is parsed, and the picture of this frame could be generated, and due to the characteristics of being broadcast live, I frame and preamble frame
It has distributed, it is impossible to send out again, so client, which needs waiting to receive next I frame, to be shown, can directly result in prolong in this way
The waiting time of first picture when long channel switching.Pass through deployment in IPTV service to improve the experience of channel switching
FCC (Fast Channel Change) server solves, as shown in figure 3, FCC server is first accessed when client request,
FCC server can quickly navigate to the I frame of caching, and I frame and subsequent frame sequence are quickly then distributed to client, client's termination
It is shown broadcasting after receiving frame sequence, meanwhile, multicast server is accessed, after the frame sequence that multicast and FCC are sent, is switched to
It is played out on multicast.Since the first frame that FCC server issues client is I frame packet forever, so terminal can quickly be shown
Channel information.
But while channel switching speed is promoted, another question is brought, to the band of the access network of user side
Width can bring biggish fluctuation, in live streaming, the influences such as Caton may be brought to play the influence of experience.Meanwhile terminal
Player receives multicast data flow and the unicast stream of FCC simultaneously, causes large effect to the cache policy etc. of player.For example, Fig. 3
The service procedure after it joined FCC server is broadcast live for the IPTV of a standard, it is assumed here that the average bit rate of channel is 1.
From figure 3, it can be seen that in step 6, the unicast stream of FCC can be sent, sent with the rate of 1+X (X > 0 therein), from this
When start the received bandwidth of terminal are as follows: the unicast stream bandwidth 1* (1+X) of FCC.Start in step 9, multicast network equipment also starts
Multicast data flow is sent to terminal device, the rate of multicast data flow is 1*1, bandwidth 1, since this moment, the received bandwidth of terminal
Are as follows: bandwidth+unicast stream bandwidth=1+1+X=2+X of multicast data flow.To the 13rd step, after finishing unicast, bandwidth is restored to group
The bandwidth for broadcasting stream is X.It is can be seen that from Fig. 3 and in being described above when providing FCC service with constant rate of speed, bandwidth maximum 2
+ X, that is, the 2 times or more of channel bit rate, it is larger to the bandwidth contributions of the access network of the network equipment, user, it is possible to lead
Cause the problems such as playing Caton.
Based on above-mentioned application background it is found that when terminal player request FCC server provides unicast media stream, FCC clothes
Business device needs quickly to navigate to from the channel of request caching apart from current time is nearest or secondary close I frame position, then by I
Frame and subsequent frame sequence are given to client.If the rate for assuming that FCC server receives multicast data flow is 1, unicast is sent to client
The rate of stream is (1+X), and X is the difference for being sent to the rate and the received multicast reception rate of the client of client.By
Fig. 3 can be seen that in step 6, and FCC sends unicast stream with the rate of 1+X (X > 0 therein), and terminal receives from now on
Bandwidth are as follows: the unicast stream bandwidth 1 of FCC × (1+X).Start in step 9, multicast network equipment also starts to send to terminal device
Multicast data flow, the rate of multicast data flow are 1 × 1, bandwidth 1, since this moment, the received bandwidth of terminal are as follows: the band of multicast data flow
Width+unicast stream bandwidth=1+1+X=2+X.When FCC server provides FCC service with constant rate of speed, bandwidth maximum 2+X,
It is exactly the 2 times or more of channel bit rate, it is larger to the bandwidth contributions of the access network of the network equipment, user, in some instances it may even be possible to cause to broadcast
The problems such as putting Caton.Therefore, in the present embodiment, during FCC server service, in order to guarantee that client is able to carry out fastly
The channel switching of speed avoids client from the problems such as playing Caton occur, below will be to this using the thought that a kind of rate reduces
The concrete methods of realizing that embodiment provides, which is given, to be described in detail.
It is understood that co-existing in following material time node, respectively T in IPTV live broadcast service1、T0、
T1、T2、T3:
| Moment | Description |
| T1 | At the time of the every IDR frame that FCC server is chosen corresponds to |
| T0 | At the time of FCC server is connected to client request FCC service |
| T1 | At the time of FCC server notifies client that multicast is added |
| T2 | At the time of the multicast sequence number that client notification receives |
| T3 | At the time of server reissues multicast sequence number |
In the present embodiment, from above-mentioned moment T2Start, namely when FCC server receives client's termination of client transmission
When receiving the message of multicast sequence number, since client has begun receiving multicast data at this time, FCC server only needs
Data cached client is sent to for remaining with low speed mode.Namely when FCC server receives client transmission
When client receives the message of multicast sequence number, preset by using receiving the first of multicast data flow rate lower than FCC server
Rate to client send FCC server it is data cached, thus reduce FCC server operation and high bandwidth output when
Between, convenient for promoting service ability, while the data volume of client process is effectively reduced, improves the efficiency and stabilization of client
Property, avoid the problems such as playing Caton.
As shown from the above technical solution, data cached transmission processing method provided in an embodiment of the present invention, when server is received
When the client sent to client receives the message of multicast sequence number, multicast data flow rate is received by using lower than server
The first scheduled rate to client send server it is data cached, thus reduce server operation and high bandwidth output
Time while effectively reducing the data volume of client process convenient for promoting service ability, improve client efficiency and
Stability avoids the problems such as playing Caton.
Content based on the above embodiment disappears in the reception that the server receives client transmission in the present embodiment
Before breath, the data cached transmission processing method further include:
Step 100: when the server receives the request service of the client, using the second scheduled rate to described
Client sends the data cached of the server；Wherein, second scheduled rate is higher than server reception multicast data flow
Rate.
In the present embodiment, the request service that the server receives the client refers to the client to unicast stream
Request service.
In embodiment, from above-mentioned moment T0Start, namely when FCC server receives the FCC request clothes of the client
When business, due to being necessary to ensure that it is data cached that client can be received quickly at this time, therefore need buffer number with higher rate
According to client is sent to, therefore, when FCC server receives the FCC request service of client, connect using the server is higher than
The second scheduled rate for receiving multicast data flow rate sends the data cached of the server to the client.
Content based on the various embodiments described above, in the present embodiment, the data cached transmission processing method further include:
The client addition group is notified to cast to the server and receive connecing for the client transmission in the server
In the period for receiving message, the slow of the server is sent to the client using the rate that the server receives multicast data flow
Deposit data.
In the present embodiment, from above-mentioned moment T1Start, will be delayed since FCC server has already been through with higher rate
" fast hair stage " that data are sent to client is rushed, therefore, the task of FCC server at this time is to ensure that client can be steady
Transition, it is therefore possible to use it is a kind of between lower first scheduled rate and higher second scheduled rate in
Etc. rates buffered data is sent to client, therefore, FCC server notice client addition group cast to FCC server receive
In the period of the reception message sent to client (namely above-mentioned T1To T2In period), it can preferably use the FCC
The rate that server receives multicast data flow sends the data cached of FCC server to client.
According to the description of embodiments above it is found that in embodiments of the present invention, three phases, respectively T can be divided into altogether0
To T1Period, T1To T2Period and T2To T3Period.Wherein, in T0To T1In period, since FCC is serviced at this time
It is data cached that device is necessary to ensure that client can be received quickly, therefore needs that buffered data is sent to client with higher rate
Therefore end is during this period of time sent using higher second scheduled rate to client data cached.And in T1To T2Time
In section, rank " is sent out for what buffered data was sent to client with higher rate fastly since FCC server at this time has already been through
Section ", therefore, FCC server need to only ensure client can smooth transition, therefore can be lower than using one kind in this period
The moderate rate (rate as received multicast data flow using the server) of second scheduled rate is sent to client to be cached
Data.And in T2To T3In period, since client has begun receiving multicast data at this time, FCC server only needs
By it is remaining it is data cached client is sent to low speed mode, therefore can be during this period of time lower than using one kind
First scheduled rate of the moderate rate sends data cached to client.It can be seen that the embodiment of the present invention is different
Period with different rates to client send server end it is data cached, and rate variation pattern be gradually decrease, thus
It the time for reducing operation and the high bandwidth output of server, convenient for promoting service ability, while effectively reducing at client
The data volume of reason improves the efficiency and stability of client, avoids the problems such as playing Caton.In addition, the embodiment of the present invention mentions
This section in different times supplied sends the data cached control mode of server end to client with different rates, realizes
Get up also relatively simple, avoid complicated control strategy, reduce the operation of FCC server, convenient for promoting service ability.
In addition, in embodiments of the present invention, it is preferable that first scheduled rate is that the server receives multicast data flow
X times of rate；Second scheduled rate is 1+X times of the rate that the server receives multicast data flow；Wherein, X is to be sent to
The unicast stream rate of the client and the difference of the received multicast data flow rate of the client.
It should be noted that working as X≤0, it will lead to when picture is slow and multicast switches of client viewing, be easy to appear
The discontinuous phenomenon of picture.If X is excessive, it will lead to picture and sound and quickly play obviously, poor user experience, in some instances it may even be possible to cause
It complains, while may result in phenomena such as FCC server buffer is used up, picture is caused to postpone, therefore, X value preferably takes a phase
To suitable value, if the value range of X is preferably 0.2≤X≤0.4, in addition, as a kind of more preferably scheme, X value can be with
It is set as 0.3.Below with reference to content shown in Fig. 4 and Fig. 5 to data cached transmission processing method provided in an embodiment of the present invention to
Give further explanation explanation.
Referring to fig. 4 and Fig. 5, the embodiment of the present invention include being respectively as follows: there are three the stage of control altogether
First stage: T0 to the T1 period (fast hair stage):
It is data cached that FCC server end is sent with the rate of 1+X, it is ensured that client can quickly receive data, meanwhile,
It has been sent as far as possible by data cached.
Second stage: T1 to the T2 period (even hair stage):
When FCC server end distribute fastly it is complete, with 1 rate send FCC server end it is data cached, it is ensured that client can
Smooth transition.
Phase III: T2 to the T3 period (slow hair stage):
