To further illustrate the present invention the flexible control of provided direct broadcast band and switching method, it is broadcast live below with court
Exemplified by illustrate：
On the whole, the present invention is realized for the flexible control of direct broadcast band with switching by Portal backstages, and
According to the different hardware configurations of each court, using different switching methods, specifically it is divided into the following two kinds situation.
In the case of there is special live streaming stream encoder in court：
Since court has the encoder of special user live broadcast video, the encoding stream exported is supplied to externally public straight
Service is broadcast, it at this time can be by being switched over to audio and video matrix, it is possible to replace the video pictures of input coding device.So only
It needs to dispose several broadcasting boxes in court, plays Xun Huan in box and export some spare video pictures, can such as be divided into and " open a court session
Several classes such as preparation video pictures ", " video pictures in dies non ", " emergent video pictures ", it is by switching audio and video matrix, this is several
A picture can be switched to be encoded for the encoder of live streaming, and is watched by network direct broadcasting to audient；It is and different standby
Which with video segment, on earth using, when switch, with regard to all by Portal backstages according to the progress rank of court's trial business
Section and current actual conditions determine, once it needing to switch, it is only necessary to Portal backstages send switching command and are regarded to sound
Frequency matrix, switches in this manner, is switched to non-court's trial picture from court's trial picture, speed is fast, does not influence to see
The viewing effect for the person of seeing, when player plays video, no blank screen, no picture stop are felt immediately.
In the case of not having special live streaming stream encoder in court：
In the case of not having special live streaming stream encoder in court, Portal background services is needed to be directed at this time
The client player being each broadcast live carries out transmission control instruction, but the Portal pages of each client are once player
After startup, the control to player is just lost, player can not be directly controlled.If each player can provide one at any time
Receive the serve port of control instruction, it is possible to receive the control instruction on Portal backstages, but synchronous needs solve currently to have
How many a player clients to receive this instruction and they to receive the address (IP address, serve port) of instruction be assorted
Etc..We are solved by following scheme：
For player, we reserve the port of special reception control instruction；After player is activated, player opens
The service of the reception is moved, if player starts network monitoring with the port given tacit consent to, and on the client machine of place
Other ports cause to conflict, then player can attempt the service listening port more renewed, until finding a port, as monitoring
Port；
Player is in live streaming URL, when obtaining data source, in step 1, and the port of the monitoring control instruction of player
Number it is advertised to streaming media server；
For each direct broadcast band issued on streaming media server, each direct broadcast band corresponds to unique URL addresses, stream
Media server is responsible for the IP address and listening port monitoring, collect, update current each player client of URL addresses
Number；
Streaming media server can judge whether the IP address of the terminal leads to streaming media server to each client ip
Fire wall or network address translation (NAT, Network Address Translation) are crossed, to turning by network address
These IP address lists changed will individually provide mark；
Several demanding channels are opened on streaming media server, these demanding channels each correspond to different URL addresses, play
Different video contents；User's players are used in switching channels；
Business background service monitors the live video picture of each court, and when finding that picture has abnormal, startup is broadcast
Put device channel switching instruction；Judge whether the court has the encoder of special live TV stream before sending instruction, if so, then directly
Audio and video switching matrix switching command being sent in court, then the live streaming picture of the broadcasting of client player brushed at once
It is newly other video pictures；
Business backstage can only be then played by Background control if it find that the court that switches is needed not have special encoder
The mode of device switches over.A row for obtaining direct broadcast band URL beholders are first inquired about on business backstage from streaming media server
Table, the port numbers for the server that the IP address comprising beholder is received with control instruction, notice that this list is not wrapped in the list
Containing these users Jing Guo network address translation；The new purpose frequency that the terminal player needs for watching the channel are switched simultaneously
The URL addresses in road are sent to streaming media server, have streaming media server to assist to complete a part of channel switching control；
Business backstage gets the address column for the player terminal that can push directly on switching command from streaming media server
After service port number of the table with receiving control instruction, successively to these IP address and port numbers transmission channel switching instruction, spare
Direct broadcast band address etc.；
After each terminal player receives this switching command and spare direct broadcast band address, stop current live frequency
The broadcasting in road is replaced other URL addresses that play parameter carries and is replayed；
Streaming media server is by the Redirect methods in RTSP agreements, by between streaming media server and player
TCP connection is pushed to new broadcasting URL addresses the player of these live streaming clients being hidden in behind NAT；Why
The instruction of the channel switching of all users is not pushed with streaming media server, streaming media server is mainly in view of and handles these
Business datum influences the data forwarding performance of streaming media server；
By the above method, the instruction that switching channels are sent to the player of all-network terminal is realized.
To sum up, the flexible control of direct broadcast band provided by the invention can solve backstage with switching method can not be to live streaming visitor
The problem of family end player is directly controlled is also ensured that operating in the live streaming client on public network and operating in fire prevention
Behind wall, the direct broadcast band switching control of the player client after NAT address conversions, while all live streamings can be reduced
Client is all controlled the influence that data performance is forwarded and convection media server by streaming media server.
Particular embodiments described above has carried out the purpose of the present invention, technical solution and advantageous effect further in detail
Describe in detail it is bright, it should be understood that the above is only a specific embodiment of the present invention, the guarantor being not intended to limit the present invention
