Embodiment
The present invention proposes a kind of data transmission method based on screen protection, the method is applied in the supervisory control system comprising VM server, VC and data transfer equipment, in live flow process (namely VC checks live data), this data transfer equipment is MS server, namely sends data (i.e. live data) by MS server to VC; In playback flow process (namely VC checks Video data), this data transfer equipment is DM server, namely sends data (i.e. Video data) by DM server to VC.
In the process of data transfer equipment to VC transmission data, (namely in live flow process, MS server sends data to VC; Or in playback flow process, DM server sends data to VC), as shown in Figure 2, the data transmission method based on screen protection provided by the invention comprises the following steps:
Step 201, VM server obtains the current screen protection state of VC, and this screen protection state is for being in screen protection state (i.e. screen protection enabled state) or not being in screen protection state (namely enabled state is gone in screen protection).
VM server obtains the current screen protection state of VC, specifically comprises:
Mode one, monitor self by when not being in screen protection state variation for being in screen protection state at VC; by VM server, the current message notice being in screen protection state to VM server, is determined that the current screen protection state of VC is for being in screen protection state by VC (can realize correlation function by the XP on VC).
Self is monitored by when being in screen protection state variation for not being in screen protection state at VC; by VM server, the current message notice not being in screen protection state to VM server, is determined that the current screen protection state of VC is not for be in screen protection state by VC.
In the present invention, the default monitoring program (by installing corresponding plug-in unit to realize when installing video monitoring software) monitored screen protection process can be installed on VC, and by presetting the situation of change of monitoring program monitoring current screen guard mode; Current by not being in screen protection state variation for after being in screen protection state at VC, VC monitors situation of change by default monitoring program, thus monitors self by not being in screen protection state variation for being in screen protection state; Current by being in screen protection state variation for after not being in screen protection state at VC, VC monitors situation of change by default monitoring program, thus monitors self by being in screen protection state variation for not to be in screen protection state.
It should be noted that; VC by HTTP (Hyper Text Transfer Protocol, HTML (Hypertext Markup Language)) message by self current be in screen protection state information or self current message notice not being in screen protection state to VM server.
In actual applications, owing to VC can there be multiple use pane, and received by different use panes and show different data, therefore VC can also carry all use pane information of self in HTTP message, in subsequent process, notification data forwarding unit stops sending data corresponding to all use panes, the handling process corresponding due to each use pane is identical, follow-uply repeats no more, and uses the process of pane to be described for one.
(this predetermined period can be selected according to practical experience according to predetermined period for mode two, VM server, such as, 10 minutes) inquire about whether VC is current is in screen protection state, and when to be that VC is current be in screen protection state (namely VC responds self and is currently in screen protection state) to Query Result, determine that the current screen protection state of VC is for being in screen protection state; When to be that VC is current be not in screen protection state (namely VC responds self and is not currently in screen protection state) to Query Result, determine that the current screen protection state of VC is not for be in screen protection state.
It should be noted that, VM server is by SIP (Session Initiation Protocol, conversation initialized protocol) message regularly inquires about whether VC is current is in screen protection state, VC is current be in screen protection state time, self current result being in screen protection state can be responded; VC is current be not in screen protection state time, can be responded self and currently not be in screen protection state.
Step 202, when the current screen protection state of VC is for being in screen protection state, VM server notification data forwarding unit stops sending data to VC.
In the present invention, in live flow process, this data transfer equipment is MS server, and VM server can utilize MAI message informing MS server to stop sending data to VC; Afterwards, MS server will directly abandon the data sending to VC send to the data of VC (namely EC sends to the data of VC by MS server) receiving after, to stop sending data to VC, namely MS server receives only the data sending to VC, but not by data retransmission to VC.
Further; determine that the current screen protection state of VC is by after to be in screen protection state variation be not in screen protection state (two kinds of modes by step 201 are known) at VM server; then VM server needs notice MS server to continue to send data to VC; afterwards; the data received directly can be sent to VC send to the data of VC (namely EC sends to the data of VC by MS server) receiving after by MS server.
It should be noted that VM server is when notifying that MS server stops sending data to VC, EC can't stop sending data to MS server, just MS server not by data retransmission to VC; Therefore, when needs continue to send data to VC, the data from EC directly can be sent to VC by MS server, do not need to re-establish the processes such as the negotiation of live data.
In the present invention, in playback flow process, this data transfer equipment is DM server, and VM server can utilize RTSP (Real Time Streaming Protocol, real time streaming transport protocol) message informing DM server to stop sending data to VC; Afterwards, DM server sends to the data of VC (namely DM server is not reading the data sending to VC from memory device) by stopping obtaining, to stop sending data to VC, namely DM server does not obtain the data sending to VC, does not send data to VC yet.
Further; determine that the current screen protection state of VC is by after to be in screen protection state variation be not in screen protection state (two kinds of modes by step 201 are known) at VM server; then VM server needs notice DM server to continue to send data (the play message by RTSP realizes) to VC; afterwards; DM server obtains again needs to send to the data of VC (namely DM server reads from memory device the data needing to send to VC), and the data of acquisition are sent to VC.
Owing to needing the temporal information of the Video data knowing playback in playback flow process, therefore can also comprise in the present invention: monitor self by being in screen protection state variation for after not being in screen protection state at VC, VC needs to be obtained from the time point s (namely before user program request to time point s) of the data be in the time period t (being in the time period t of screen protection state by starting timer record self) of screen protection state and playback before being in screen protection state; Afterwards, VC by the message notice of time period t and time point s to VM server; VM server notice DM server continues to data corresponding to VC transmitting time section t and time point s, by DM server from time point s adds data corresponding to time period t (namely playback duration is time period t+time point s), again obtain the data sending to VC, and the data of acquisition are sent to VC.
Such as; before being in screen protection state, the time point s of playback of data is 2011.10.10.08.10.10; and the time period t being in screen protection state is when being 30s, then DM server needs from the data that 2011.10.10.08.10.40 is corresponding, again obtains the data sending to VC.
It should be noted that, VM server continues to data corresponding to VC transmitting time section t and time point s by the play message informing DM server of RTSP, and VM server only needs to add above-mentioned time period t and time point s sum (for starting the time of playing) in the clock field of play message.
