Specific implementation mode
Fig. 1 is history video dispatching retransmission method flow chart provided in an embodiment of the present invention；Fig. 2 carries for the embodiment of the present invention
The structure chart of the scheduling system of confession.For the embodiment of the present invention in the prior art, shortage dispatching desk is scheduled history video
The realization mechanism of distribution, provides history video dispatching retransmission method, and this method is as follows：
Step S101, dispatching desk obtains history video from video and audio recording server.
As shown in Fig. 2, scheduling system provided in an embodiment of the present invention includes dispatching desk 21, video and audio recording server 22, adjusts
Server 23 is spent, the executive agent of the present embodiment is the dispatching desk 21 in scheduling system.In scheduling system, video and audio recording service
Device 22 is stored with history video, and dispatching desk 21 can retrieve the history for obtaining and being stored in video and audio recording server 22 according to search condition
Video, search condition can be the content letters for recording time information, history video of the source-information of history video, history video
Breath etc..In the present embodiment, dispatching desk 21 is integrated with scheduling controlling interface, can retrieve, download, playback history video, also may be used
It to be scheduled operation to video, such as distribution, uploads etc., user is by the scheduling controlling Interface Control dispatching desk 21 from recording
History video is obtained in recording service device 22.For example, step 1a shown in Fig. 2, dispatching desk 21 is sent out to video and audio recording server 22
History video tour control instruction is sent, indicates the history video in the request browsing video and audio recording of dispatching desk 21 server 22, recording
The history video tour control instruction that recording service device 22 is sent according to dispatching desk 21 sends history video, such as to dispatching desk 21
Step 1b shown in Fig. 2.
Step S102, the described dispatching desk plays the history video.
After dispatching desk 21 receives the history video of the transmission of video and audio recording server 22, the history video is played in real time.
Step S103, the described dispatching desk sends history video distribution order to dispatch server, so that the dispatch service
Device establishes the session relationship between at least one user equipment and the video and audio recording server so that the video and audio recording service
The history video is sent to the dispatch server by device by the session relationship, and the dispatch server is by the history
Video distribution gives at least one user equipment.
During playing the history video in real time, dispatching desk 21 can also give the history video distribution dispatching desk 21
At least one user equipment 24, in other embodiments, dispatching desk 21 can give the history video distribution to multiple user equipmenies.
The history video distribution is by dispatching desk 21 to the detailed process of at least one user equipment 24：Dispatching desk 21 is to tune
It spends server 23 and sends history video distribution order, step 2 as shown in Figure 2, dispatch server 23 receives history video point
After saying the word, the session relationship between user equipment 24 and video and audio recording server 22 is established.Dispatch server 23 establishes user
The detailed process of session relationship between equipment 24 and video and audio recording server 22 is：As shown in the step 3 of Fig. 2, dispatch service
Device 23 establishes session relationship with user equipment 24, and as shown in the step 4 of Fig. 2, dispatch server 23 and video and audio recording service
Device 22 establishes session relationship, and meeting is established by dispatch server 23 to realize user equipment 24 and video and audio recording server 22
Words relationship.Dispatch server 23 is established with video and audio recording server 22 after session relationship, as shown in the step 5 of Fig. 2, recording record
As the history video dubbing portion that server 22 sends it to dispatching desk 21 is sent to dispatch server 23, dispatch server 23
Give the history video distribution at least one user equipment 24, i.e., as step 6 of figure 2, dispatch server 23 is set to user
Standby 24 send historical video streams.User equipment 24 plays out after receiving historical video streams so that user equipment 24 played
History video is consistent with the history video that dispatching desk 21 plays, i.e. the broadcasting picture of the broadcasting pictures of user equipment 24 and dispatching desk 21
Face is consistent.
The embodiment of the present invention obtains history video by dispatching desk from video and audio recording server, and is sent to dispatch server
History video distribution order, so that dispatch server establishes the session between at least one user equipment and video and audio recording server
Relationship so that history video is sent to dispatch server by video and audio recording server by session relationship, and dispatch server will be gone through
History video distribution gives at least one user equipment, realizes the mechanism of history video dispatching forwarding.
Fig. 3 is the history video dispatching retransmission method flow chart that another embodiment of the present invention provides；Fig. 4 is that the present invention is another
The signaling diagram for the history video dispatching retransmission method that embodiment provides.History video dispatching retransmission method provided in this embodiment
It is as follows：
Step S301, the described dispatching desk sends the request of history video playing to the video and audio recording server.
Specifically, the dispatching desk sends history according to real time streaming transport protocol RTSP, to the video and audio recording server
Video playing is asked.
Step 41 as shown in Figure 4, dispatching desk send the request of history video playing, scheduling to the video and audio recording server
Based on real time streaming transport protocol (Real Time Streaming Protocol, abbreviation between platform and video and audio recording server
RTSP it) is communicated.
Step S302, the described dispatching desk receives the video and audio recording server and asks to send according to the history video playing
The history video.
Specifically, the dispatching desk receives what the video and audio recording server was sent according to history video playing request
Realtime Transport Protocol data packet, the Realtime Transport Protocol data packet carry the history video.
Step 42 as shown in Figure 4, video and audio recording server send real-time transport protocol (Real-time to dispatching desk
Transport Protocol, abbreviation RTP) data packet.
Step S303, the described dispatching desk plays the history video.
Step S304, the described dispatching desk sends history video distribution order to dispatch server, so that the dispatch service
