Embodiment
The embodiment of the invention relates to the live professional realization of video, and the realization of video storage playback business, respectively the implementation procedure of two kinds of business is described in detail below in conjunction with accompanying drawing.
Referring to Fig. 2, be the live professional schematic flow sheet of the video in the embodiment of the invention.This flow process has been described based on video monitoring system shown in Figure 1, the live professional specific implementation process of video.As shown in the figure, this flow process can comprise:
Step 201, video terminal is initiated video traffic request message (the live telecast request of having access to as video) to SCM, and this message carries following user profile, and these information can be imported by the user:
Parameter A 1: motion detection boundary information and detected object size threshold values;
Parameter A 2: mass motion metered valve value, i.e. video image motion total amount threshold value;
Parameter A 3: do not accept the maximum duration of video flowing, the maximum duration of the not receiver, video stream that is promptly allowed;
Parameter A 4: the video pixel information that the user is provided with, as (w, h).
Wherein, the effect of each parameter and implication are described as follows:
Parameter A 1: being mainly used in the video camera visual range, drawing some object of which movement borders, can be the rectangle of one or more sealings, also can be one or more straight line.When passing across the border, represent that this video image is the user's interest video image as the object (being the object of size) of certain size more than or equal to the inspected object size threshold value;
Parameter A 2: be used to be provided with total video motion threshold values, when this threshold values that the video motion amount of current video is set more than or equal to the user, the expression current video image is the user's interest video image;
Parameter A 3: in order to compensate owing to the accumulative total that does not have video transmission to cause some videos to change for a long time, can upgrade the video of video terminal in maximum cycle, parameter A 3 has defined should the maximum update cycle.Further, when fault detect,, then can think to have produced fault if do not detect video in indicated cycle in parameter A 3.
Parameter A 4: expression video terminal acceptable Pixel Information, the flow of the high more video data of pixel also can be big more, and the user can dynamic according to demand setup parameter A4.
In the above parameter, parameter A 1, parameter A 2 and parameter A 3 are foundations that SCM judges whether to satisfy the forwarding condition, can be referred to as motion detection parameters or motion detection information, and wherein parameter A 3 is an optional parameters; Parameter A 4 is foundations that video encoder is encoded.There are certain complementation in parameter A 1 and parameter A 2, and as in some outdoor environments, what overall threshold values (parameter A 2) can be provided with is higher relatively, adds some object of which movement boundary informations (parameter A 1) simultaneously.As when to a tree and surrounding environment when monitoring, can the wind tree is moving not to cause too much video Data Transmission because of having, and during the borderline region around the people enters tree, can in time trigger the video relevant treatment again.
In the step 201, SCM can receive the video live telecast of a plurality of video terminals initiations and have access to request message.
Step 202, after SCM receives the video traffic request message of video terminal, the user profile that record wherein carries, and notice EC starts coding.
In this step, SCM can start coding, the following information of portability in this indication information by sending indication information notice EC:
B parameter 1: can there be a plurality of motion detection border in the motion detection boundary information; B parameter 1 can determine according to the motion detection boundary information in the parameter A 1, and when being video image the first half 1/2 regional as the motion detection zone of parameter A 1 expression, this B parameter 1 is parameter A 1;
Minimum pixel value after cutting apart when B parameter 2:EC encoder is cut apart video image, the video pixel information that B parameter 2 is asked according to video terminal by SCM (being parameter A 4) is calculated and is obtained, this minimum pixel value is not more than the video pixel value (being parameter A 4) that video terminal is asked, when SCM receives the video traffic request of a plurality of video terminals, this minimum pixel value is not more than the set A4 parameter of any video terminal user, it can be the greatest common divisor of the set parameter A of each video terminal 4, promptly, horizontal direction pixel value in the B parameter 2 is: the greatest common divisor of the pixel value in the set parameter A 4 of each video terminal user on the horizontal direction, the vertical direction pixel value in the B parameter 2 is: the greatest common divisor of the pixel value in the set parameter A 4 of each video terminal user on the vertical direction.
Need to prove, SCM is when determining the minimum common pixels of each video terminal according to the method for getting greatest common divisor, then the numerical value of the greatest common divisor that might calculate is less, will increase the complexity and the synthetic complexity of subsequent video stream of image segmentation like this.In such cases, the numerical value of desirable one approximate greatest common divisor is as B parameter 2.
For example, parameter A 4 differences of carrying in the request message of different video terminals, the parameter A 4 that is provided with as the cellphone subscriber may be (176 * 144 pixel), the parameter A 4 that the PC user is provided with may be (720 * 576 pixel).Comprise promptly that at the video terminal of initiating request the cellphone subscriber comprises pc user's situation again, the parameter A 4 that the desirable cellphone subscriber of SCM is provided with is (176 * 144 pixel) as each video terminal user's minimum common pixels; If the both is the PC user, then minimum pixel is (720 * 576).Can prepare for follow-up SCM transmits to the video data of video terminal like this,, thereby save data traffic for the cellphone subscriber if the cellphone subscriber only needs to transmit the video of (176 * 144) pixel.Can be fit to the requirement of different users like this, consider the characteristics that some user terminals are charged by flow, satisfy this part user's charging demand pixel.
Step 203, EC carries out video coding according to the indication information of receiving.
Concrete, the video coding process of EC can comprise: go out the motion total amount information of present image according to the former frame image calculation, promptly the motion total amount of present image reality is expressed as parameters C 1, and parameters C 1 is that SCM judges whether one of foundation of transmitting video flowing; Motion detection boundary information (being B parameter 1) according to video terminal user setting, calculate the size (being expressed as parameters C 2) of largest object in the object that passes through detection boundaries, if exist a plurality of detection boundaries then correspondence have a plurality of parameters C 2, parameters C 2 is that SCM judges whether one of foundation of transmitting video flowing; Carry out the video dividing processing according to 2 pairs of frame of video that receive of B parameter, and each frame of video after cutting apart encoded respectively, can on the frame of video behind the coding, stamp label,, after making things convenient for the video terminal decoding, carry out the video reorganization to distinguish segmentation times or image pixel value.
Concrete, the process that EC is cut apart frame of video can comprise:
Steps A, EC are carried out the interlacing sampling to view data, and the image pixel value that obtains after sampling carries out every the row sampling the arbitrary parts of images data that obtain after this sampling during still greater than described minimum pixel value; If the image pixel value that obtains after the interlacing sampling is equal to or less than described minimum pixel value, then finish the sample process process;
When step B, EC judge that the image pixel value that obtains is still greater than described minimum pixel value after the row sampling, choose the arbitrary parts of images data that obtain after the sampling and change steps A over to; If the image pixel value that obtains is equal to or less than described minimum pixel value, then finish the sample process process after the row sampling.
Above-mentioned flow process can mainly comprise as shown in Figure 3:
Step 301 is carried out the interlacing sampling to view data.As, be split as odd-numbered line L1 and even number line L2 two parts data.
Step 302, the image pixel after the judgement sampling are equal to or less than minimum pixel (being B parameter 2), if then finish sampling process; Otherwise, change step 303 over to.
Step 303 is chosen a part of view data wantonly and is changed step 304 over to from the view data after sampling last time, as choose the view data of odd-numbered line L1 from two parts data of odd-numbered line L1 and even number line L2.
Step 304 is carried out every the row sampling view data.As L1 partial data, after the row sampling, obtain L11, L12 two parts data to selecting.
Step 305, the image pixel after the judgement sampling are equal to or less than minimum pixel (being B parameter 2), if then finish sampling process; Otherwise change step 306 over to.
Step 306 is chosen a part of view data wantonly and is changed step 301 over to from the view data after sampling last time, as chooses the view data of L11 part and change step 301 over to.
For example, if through after cutting apart for n time, obtain B parameter 2 and be that (then above-mentioned cutting procedure can be as shown in Figure 4 for w0, frame of video h0), wherein the video data of the different pixel values that obtains after partly representing to cut apart of solid line.
Certainly, also can carry out earlier carrying out the interlacing sampling again every the row sampling.(W H) under the situation identical with B parameter 2, then need not to carry out the video image dividing processing in the pixel of the video flowing of input.
Step 204, the information that SCM is provided with when submitting the video traffic request to according to the video terminal of preserving judges whether video flowing to be transmitted to this video terminal, and when satisfying the forwarding condition, the video flowing of transmitting after EC encodes is given this video terminal.
Concrete, for a video terminal of initiating the video traffic request, SCM is transmitted to this video terminal with the video flowing behind the EC coding when judgement one of meets the following conditions:
D1: according to the moving boundaries that this video terminal is provided with, during object size threshold value in the parameter A 1 that the object size parameter C2 that passes through detection boundaries is provided with greater than this video terminal; This kind situation shows that the object that has size to surpass setting threshold has passed through detection boundaries, has promptly entered surveyed area;
D2: during parameter A 2 that the motion total amount parameters C 1 of current video frame is provided with greater than this video terminal; This kind situation shows that bigger variation may take place current video image;
D3: last time is when having surpassed the parameter A 3 of this video terminal setting to the difference of time that this video terminal is transmitted video flowing and current time; This kind situation shows that having longer a period of time to change video terminal does not receive video flowing.
Wherein, above-mentioned Rule of judgment D3 is an optional condition.
SCM is after above-mentioned forwarding condition is satisfied in judgement, can be to the video flowing after video terminal is transmitted coding, repeating process can be: the parameter A 4 that SCM is provided with according to this video terminal, whether check in the video flowing after current EC encodes has pixel value to meet the video flowing of parameter A 4, if there is the satisfactory video flowing of pixel then to transmit this video flowing, otherwise the pixel according to each video flowing behind the coding makes up transmission to video flowing.
Wherein, when the set parameter A 4 of video terminal user be 2 nDoubly when B parameter 2, the video flowing with respective pixel values that SCM will obtain after will encoding sends to this video terminal; When the set parameter A 4 of video terminal user is not an above-mentioned parameter (promptly 2 nDoubly to B parameter 2) time, at least 2 video flowings that SCM will obtain after will encoding send to this video terminal, and total pixel count of these video flowings should be not less than the set parameter A of this video terminal 4, wherein, n 〉=0.For example, be example with video segmentation result shown in Figure 3, the minimum pixel B2 of the video flowing behind the EC coding be (w0, h0), then:
The parameter A 4 that is provided with when video terminal be (4w0, in the time of 4h0), directly (4w0 4h0) sends to this video terminal to SCM, and this send mode can be described as direct transmission with 4 times of video flowings to B parameter 2;
The parameter A 4 that is provided with when video terminal is (3w0, in the time of 3h0), SCM is with 1 times of video flowing (w0 to B parameter 2, h0) and 2 times to the video flowing (2w0 of B parameter 2,2h0) send to this video terminal, so that this video terminal synthesizes pixel for (3w0, video flowing 3h0), this send mode can be described as combination and send with this 2 road video flowing;
The parameter A 4 of the setting in video is (7w0, in the time of 7h0), SCM is with 4 times of video flowing (4w0 to B parameter 2,4h0), 2 times to the video flowing (2w0 of B parameter 2,2h0) (w0 h0) sends to this video terminal, is (7w0 so that this video terminal synthesizes pixel with this 3 road video flowing with 1 times of video flowing to B parameter 2, video flowing 7h0), this send mode is the combination send mode.
Step 205, video terminal carries out decoding and displaying according to the video flowing that receives.Wherein, the video flowing that receives when video terminal is when making up the video flowing that sends, also to need each road video flowing is recombinated after respectively each decoding video stream being finished, and the video image pixel after the reorganization is the video pixel that this video terminal is asked.

In order to save the EC resource, in another embodiment of the present invention, if SCM judges the current video terminal initiation video traffic request (promptly being in idle condition) that do not have, then SCM can dynamically close the encoding process of EC.The video traffic type of EC comprises two classes: the video data of specifying camera is had access in video terminal request live telecast, and has RD the video data of specifying EC need be saved on the storage medium (generally to customize this business by setting the video storage plan).If EC does not have above-mentioned two kinds of service request, represent that promptly current EC is in idle condition, SCM can close EC that should the free time.
In order to increase the maintainability of whole video system, in another embodiment of the present invention, video terminal can also carry out fault detect, concrete, do not receive video data in the duration in appointment, then carry out alarm, cue circuit or equipment may take place unusually, thereby can in time note abnormalities and prompting in time, strengthen the maintainability of video system.Wherein, the duration of the described appointment set parameter (as above-mentioned parameter A 4) that can be video terminal when initiating the video traffic request also can be the unified parameter of setting of video system.
Usually, the video storage operation flow can walk abreast with the live operation flow of video and carry out.Concrete, when the live business of video was carried out, SCM currently satisfied when memory RD transmits the condition that video flowing stores judging, the video data of SCM buffer memory is transmitted to memory RD.The forwarding condition can with the live operation flow of video in to transmit the Rule of judgment of video flowing to video terminal identical.Wherein, can open up buffer area in advance among the SCM, be used for the video data encoder of buffer memory EC, the big I of this buffer area is according to the configuration parameter adjustment.Its flow process mainly may further comprise the steps:
The video terminal that is used to dispose RD sends storage configuration parameter to SCM, and these parameters can comprise:
Parameter A 1: motion detection boundary information and detected object size threshold values;
Parameter A 2: mass motion metered valve value, i.e. video image motion total amount threshold value;
Parameter A 3: do not accept the maximum duration of video flowing, the maximum duration of the not receiver, video stream that is promptly allowed;
Parameter A 4: the video pixel information that the user is provided with;
Parameter A 5: data buffer area size.
Wherein, the effect of parameter A 1～A4 and implication do not repeat them here as previously mentioned.
Follow-up processing can be basic identical with step 202～204 in the flow process shown in Figure 2, that is, SCM writes down above-mentioned storage configuration parameter, and notice EC starts coding; EC carries out video coding according to the indication information of receiving; SCM judges whether video flowing to be transmitted to RD equipment according to the storage configuration parameter of preserving, and when satisfying the forwarding condition, the video flowing of transmitting after EC encodes is given RD equipment.
Wherein, SCM opens up data buffer area according to parameter A 5, the video data that buffer memory is certain.When SCM detects need transmit the time (it is identical with forwarding condition judgment in the video live telecast operation flow to transmit condition judgment), can when video flowing is transmitted to video terminal, the video data in the buffer area also be transmitted to memory RD.
In order to increase the maintainability of whole video system, in another embodiment of the present invention, RD can also carry out storage failure and detect.Concrete, RD does not receive video data in the duration in appointment, then can point out contingent unusual by reporting message.Wherein, the duration of the described appointment set parameter (as above-mentioned parameter A 4) that can be video terminal when initiating the video traffic request also can be the unified parameter of setting of video system.
