Below in conjunction with the accompanying drawings, method provided by the invention and associated terminal are described in detail with specific embodiment.
Embodiment 1：
In the embodiment of the present invention 1, a kind of method of terminal screen live streaming is provided, as shown in Fig. 2, specifically including following step
Suddenly：
S201, the first access terminal access live streaming terminal after, determine the excellent of the first access terminal according to preset rules
First grade.
In this step, priority can be determined according to first access terminal of the preset rules for access.Such as：It can basis
The access sequencing of first access terminal determines priority, i.e., the priority that the first access terminal of more early access determines is more
It is high；Or priority is determined according to the performance of the first access terminal, i.e. the first better access terminal of performance determines preferential
Grade is higher；Or determine priority according to the registration scenarios of the first access terminal, that is, the member's rank registered it is higher first
The priority that access terminal determines is more high, and specific preset rules can be configured according to actual needs, be not intended to limit here.
Further, determine that the action of priority is automated execution in this step for the first access terminal, it can also root
It modifies manually to the priority automatically determined out according to needs, such as：According to the access sequencing of the first access terminal come
When determining priority, for rear access, and higher the first access terminal of member's rank for registering can also be carried manually
Its high priority.
For the ease of the priority determined for different first access terminals is managed and subsequently definite code check when pair
Priority is inquired about, and can establish priority list.It is preferred that it can be asked in the access for receiving first the first access terminal
The priority list is established when asking, and is recorded as between priority and first access terminal that each first access terminal determines
Correspondence.
S202, the corresponding code check of priority determined in S201 is distributed for the first access terminal.
In order to solve in the prior art, to be that more matchmakers are broadcast live all in accordance with identical and high code check generation in each first access terminal
Body stream is simultaneously sent, and causes packet loss so that the first access terminal play the slack problem of media stream, can pre-set to
Few two code checks, and each code check is made to correspond to one group of priority；Every group of priority includes at least one priority, and comprising it is excellent
The higher corresponding code check of one group of priority of first grade is higher.
That is, when the first number of access terminals is less, every group of priority can be made to include a priority, i.e., it is every
A code check corresponds to a priority, and different code checks is used to generate live multimedia for the first access terminal of different priorities
Stream, compared with same high code check is used to generate live multimedia code check for the first different access terminals, the code check of use has height
Have low, packet drop can be alleviated, solve the problems, such as that the first access terminal live multimedia stream is slack.
Further, when the first number of access terminals is more, generated respectively based on correspondence for each first access terminal
The live multimedia stream resource consumption of code check is larger, and every group of priority can be made to include at least two priority, each code check pair
One group of priority is answered, can also solve problems of the prior art.Specifically, it is assumed that pre-set three code checks, i.e.,
Include the first code check, the second code check and third yard rate from high to low.It is 1000- that can make the corresponding one group of priority of the first code check
900, the corresponding one group of priority of the second code check is 899-800, and the corresponding one group of priority of third yard rate is 799-700.As it can be seen that
The first access terminal of difference of corresponding same group of priority, has different priority, but can be corresponding with identical code check.
Such as：The first access terminal of difference of the priority of 1000-900 is respectively provided with, the priority having is different, i.e. 1000-900,
But identical code check can be corresponding with, i.e. the first code check.
Also, comprising priority it is higher the corresponding code check of one group of priority it is higher, so with higher priority
First access terminal can just use the live multimedia stream based on high code rate generation, and first with lower priority connects
Enter terminal to use based on the live multimedia stream generated compared with low bit- rate.In this way, every group of first access terminal can be directed to, using this
The first access terminal of group corresponds to the code check generation live multimedia stream corresponding to priority, is sent to this group of terminal, both controlled
System resource, and solve the problems of the prior art, packet drop can be alleviated, the first access terminal is solved and play more matchmakers
The slack problem of body stream.
S203, the live multimedia stream that will be generated according to the code check distributed in S202, are sent to the first access terminal.
As above-mentioned, larger system can be consumed by regenerating live multimedia stream if each first access terminal
Resource, therefore, for the first access terminal generate live multimedia stream before, can check whether it is existing according to for this first
The live multimedia stream of the code check generation of access terminal distribution, if in the presence of can be directly transmitted, if being not present, then perform
Generation operation, this step can be performed as following steps：
If Step 1: there is currently having generated live multimedia stream, the live multimedia stream is according to for corresponding access terminal
The code check generation of distribution, then be sent to the correspondence access terminal by the live multimedia stream；
If Step 2: there is currently no live multimedia stream has been generated, which accesses eventually according to be corresponding
The code check generation of end distribution then generates live multimedia stream according to the code check for corresponding access terminal distribution, and it is right to be sent to this
Answer access terminal.
In step 203, the correspondence access terminal in step 1 and step 2 can be the first access terminal.
S204, packet loss monitoring is carried out to the live multimedia stream sent to the first access terminal.
In this step, packet loss monitoring can be carried out during being broadcast live to the first access terminal, until live streaming finishes.
When it is implemented, can be monitored by the first access terminal to the live multimedia stream received, and by packet loss
Situation notice live streaming terminal, when packet loss reaches default packet loss threshold value can also be notified with periodic advertisement, be only here
Citing, specific embodiment determines according to actual conditions, are not intended to limit here.
S205, when monitoring that packet loss is more than default packet loss threshold value, determine the of priority less than the first access terminal
Two access terminals.
In this step, when monitoring that packet loss is more than default packet loss threshold value, priority can be connect less than first first
The second access terminal for entering terminal is handled, and specific processing mode is shown in subsequent step.
S206, judge whether the current code check distributed as the second access terminal determined in S205 is pre-set code check
In lowest bit rate, if it is not, then entering step S207；Otherwise, S209 is entered step.
S207, distributed for the second access terminal in pre-set code check less than the code for being currently the distribution of the second access terminal

Rate then distributes in pre-set code check for the second access terminal and is less than the first of the code check for being currently the distribution of the second access terminal
Code check.
In this step, by reducing code check of the priority less than the second access terminal of the first access terminal, to reduce the
The bandwidth that two access terminals occupy can alleviate the packet drop of the first access terminal, be carried out so as to increase by the first access terminal
The smooth degree of live streaming.
It is preferred that the first code check belongs to pre-set code check, and for less than it is current be that the second access terminal distributes code check
Code check in maximal rate.In order to ensure the live streaming smoothness degree of the second access terminal, it is straight can be slowly reduced to its generation
The code check being based on during playing multimedia stream, if using pre-set at least two code check as at least two code check shelves, it can be with
The code check of the second access terminal is first dropped one grade.
S208, the live multimedia stream that will be generated according to the first code check distributed in S207, are sent to the second access terminal.
Enter step S204.
This step may be implemented as step：
If Step 1: there is currently having generated live multimedia stream, the live multimedia stream is according to for corresponding access terminal
The code check generation of distribution, then be sent to the correspondence access terminal by the live multimedia stream；
If Step 2: there is currently no live multimedia stream has been generated, which accesses eventually according to be corresponding
The code check generation of end distribution then generates live multimedia stream according to the code check for corresponding access terminal distribution, and it is right to be sent to this
Answer access terminal.
In the step of step S208 one and step 2, corresponding access terminal can be the second access terminal, and corresponding access is eventually
The code check of end distribution can be newly assigned first code check.
S209, when for the code check of the first access terminal distribution not being currently the lowest bit rate in pre-set code check,
The second code that is less than the code check that is currently first access terminal distribution is distributed for the first access terminal in pre-set code check
Rate.
In this step, if the code check currently distributed for the second access terminal is the lowest bit rate in pre-set code check,
And the current code check for the distribution of the first access terminal is not the lowest bit rate in pre-set code check, then is the first access terminal
It distributes in pre-set code check and is less than the second code check of the current code check for the distribution of the first access terminal.
In this step, due to priority less than the first access terminal the second access terminal code check be reduced to it is minimum,
And be that lowest bit rate in pre-set code check has not yet been reached in the code check of the first access terminal distribution, it can be by being reduced to the
The code check of one access terminal distribution to reduce the bandwidth of the first access terminal occupancy, can alleviate the packet loss of the first access terminal
Situation, so as to increase the smooth degree of live streaming.
It is preferred that the second code check belongs to pre-set code check, and for less than it is current be that the first access terminal distributes code check
Code check in maximal rate.In order to ensure the live streaming smoothness degree of the first access terminal, it is straight can be slowly reduced to its generation
The code check being based on during playing multimedia stream, if using pre-set at least two code check as at least two code check shelves, it can be with
The code check of the first access terminal is first dropped one grade.
S210, the live multimedia stream that will be generated according to the second code check distributed in S209, are sent to the first access terminal.
Enter step S204.
This step may be implemented as step：
If Step 1: there is currently having generated live multimedia stream, the live multimedia stream is according to for corresponding access terminal
The code check generation of distribution, then be sent to the correspondence access terminal by the live multimedia stream；
If Step 2: there is currently no live multimedia stream has been generated, which accesses eventually according to be corresponding
The code check generation of end distribution then generates live multimedia stream according to the code check for corresponding access terminal distribution, and it is right to be sent to this
Answer access terminal.
In the step of step S210 one and step 2, corresponding access terminal can be the first access terminal, and corresponding access is eventually
The code check of end distribution can be newly assigned second code check.
In the embodiment of the present invention, the packet drop of the first access terminal can be monitored, when the first access terminal
When packet loss reaches default packet loss threshold value, the corresponding code of the second access terminal of the first access terminal is less than by reducing priority
Rate, to alleviate the packet drop of the first access terminal, when the corresponding code check of the second access terminal has been reduced to minimum, Ke Yitong
Crossing reduces the corresponding code check of the first access terminal, to alleviate its packet drop, so that the live streaming of the first access terminal is more suitable
Freely.It is the different priority that the first different access terminals determines as it can be seen that in the embodiment of the present invention, when any first access
When packet loss occurs for terminal, connect by adjusting priority less than the code check of the second access terminal of the first access terminal or first
Enter the code check of terminal itself, it is from start to finish straight all using identical high code check generation in the prior art, being broadcast live to alleviate packet loss
