Wherein, the c attributes in this message include IP and port number information with m attributes；A attributes include coded format.Should
Understand, form above is example value, is changed according to actual environment, but is all the definition of the SDP message of the standard that follows.
P7~P9:Session Initiation Protocol message according to standard, sets up the video flowing for completing S3 steps, and now, P7 is carried at media
The SDP message of reason equipment, P8 returns to the SDP message with the coding/decoding apparatus of medium processing device pairing.
Particularly point out, the video media stream information that S3 points are received, before returning to video by S2, S1 point, can be according to above
Signaling negotiation message, make video scaling treatment, specifically, the video of S3 is defined by HD video, when the video point that S3 is returned
Video resolution size of the resolution more than S2, S1, then make video diminution treatment；When the video resolution that S3 is returned is equal to S2, S1
Video resolution size, then directly forward；When video resolution of the video resolution less than S2, S1 that S3 is returned, then by S3
The video that point is received is that, with reference to filling, the region of lack of fill is supplemented with black, afterwards will with the central point of the video image of S2
The video of filling returns to S2 points.
P10~P15:Session Initiation Protocol message according to standard, sets up the video flowing for completing S4 steps, and now, P10 is carried and divided
The SDP message of portion's monitor terminal, the P11 transparent transmissions SDP message, P12 returns to the medium processing device with branch's monitor terminal pairing
SDP message, the P12 transparent transmissions SDP message；During medium processing device is the step of P11, according to the account of the camera retrieved for examination,
The camera resource that judgement treatment is retrieved for examination is same, then according to previously mentioned video scaling treatment mechanism, by Video processing
After be then forwarded to branch's monitor terminal, but making scaling before processing, if it is judged that, there is the identical resolution of scaling treatment
The video flowing of rate, then be transmitted to S4 points after the video flowing after scaling directly being made into copy process.
It should be appreciated that on stream, the video flowing process that S3 sets up can shift to an earlier date the video flowing process set up in S1, S2, only
Before requiring modification to the INVITE signaling sequences of coding/decoding apparatus A, so, meet video by adjusting the signaling sequence in flow
The treatment of distribution, also in the shielded scope of this patent.
The present invention provides a kind of dispensing device of monitor video, including monitor terminal, monitoring server, media handling set
Standby, coding/decoding apparatus, camera；The invention further relates to a kind of distribution method of monitor video；The present invention realizes branch's monitoring eventually
When the video of control point is retrieved for examination at end, the video flowing do not set up again in coding/decoding apparatus, but, directly from media handling
After equipment compares treatment as video, distribution video is flowed in branch's monitor terminal, saves video stream data, while follow-up any prison
Control terminal retrieves for examination the camera video of control point, is all to distribute data after comparing treatment from medium processing device, has broken monitoring
The limitation of the video call number of point, the signaling message of saving sets up the video stream transmission procedure of process and big data quantity；
The present invention optimizes video flowing call processor system of the medium processing device to camera resource, so as to carry under limited bandwidth
Bandwidth availability ratio high.
The above, only presently preferred embodiments of the present invention not makees any formal limitation to the present invention；It is all
The those of ordinary skill of the industry can shown in by specification accompanying drawing and the above and swimmingly implement the present invention；But, it is all
Those skilled in the art without departing from the scope of the present invention, are done using disclosed above technology contents
The equivalent variations of a little variation, modification and evolution for going out, are Equivalent embodiments of the invention；Meanwhile, it is all according to of the invention
Variation, modification and evolution of any equivalent variations that substantial technological is made to above example etc., still fall within skill of the invention
Within the protection domain of art scheme.
