In coding, the timestamp of the frame of video for blocking video data same complete video picture corresponding with the unshielding video data is kept completely the same.
It should be noted that, in example embodiment 1, the description information of the occlusion area is that monitor supervision platform is sent to the monitoring frontend, alternatively, and the description information of the occlusion area can also be what is pre-set on the monitoring frontend.
Step 404:By generation block video data and unshielding video data is sent to the monitor supervision platform-preferably, monitoring frontend can also send the data type for blocking video data to the monitor supervision platform, to cause the monitor supervision platform is identified from the video data received to block video data, can be specifically be sent to the monitor supervision platform be used for obtain the acquisition address for blocking video data（Such as URL) include the data type（The monitor supervision platform can obtain this to the monitoring frontend using the acquisition address and block video data）Can also be includes the data type in the message for being used to carry the acquisition address for being sent to the monitor supervision platform, can also be and sends the data type during the media channel that video data is blocked for transmitting between monitor supervision platform and monitoring frontend is set up.
Step 405:First monitor terminal sends video request to monitor supervision platform, and the video request includes the device identification of the monitoring frontend；
Step 406:Judge the user of first monitor terminal whether have obtain described in block the first authority for blocking video data in video data, described first blocks video data the first occlusion area of correspondence, and first occlusion area includes the part or all of region in the occlusion area；
If it is judged that being yes, step 407A-409A is performed;
If it is judged that being no, step 407B-408B is performed.
Step 407A:Monitor supervision platform sends the description information of first occlusion area to the first monitor terminal；Step 408A:The monitor supervision platform blocks video data by described first and unshielding video data is sent to first monitor terminal； Step 409A:The first of the first monitor terminal merging broadcasting reception blocks video data and unshielding video data.
Preferably, merge broadcasting reception according to the description information of first occlusion area first blocks video data and unshielding video data.
Specifically, if described first, which blocks video data, includes video data all the way, decode described first and block video data and draw and block video data frame, decode the unshielding video data and draw unshielding video data frame, extract the pixel data blocked in video data frame, and being added to the pixel data of extraction according to the description information of the first occlusion area with the video data frame that blocks there is the corresponding pixel region of the first occlusion area described in the unshielding video data frame of identical time stamp to generate complete video frame, and play the complete video frame.If it by the corresponding video pictures direct coding of first occlusion area is described first to block video data in coding to be, the i.e. described video data frame that blocks only includes the pixel data of the corresponding video pictures of the occlusion area, the pixel data blocked in video data frame is then extracted specifically, blocking all pixels data in video data frame described in extraction；If the corresponding video pictures in de-occlusion region in whole video pictures are blocked into the pixel data of frequency picture and the pixel data of filling using described in coding generation after the pixel value filling of setting in coding, the pixel data for blocking the corresponding pixel region of the first occlusion area in video data frame is extracted according to the description information of first occlusion area.
If described first, which blocks video data, includes multi-path video data, decode described first and block being drawn per video data all the way in video data and block video data frame per video data all the way, decoding unshielding video data draws unshielding video data frame, extract the pixel data blocked in video data frame with identical time stamp of each road video data, and being added to the pixel data of extraction with the video data frame that blocks there is in the unshielding video data frame of identical time stamp the corresponding pixel region of first occlusion area to generate complete video frame, and play the complete video frame.
Specifically, as shown in Fig. 6, the unshielding video data and described first blocks video data and transmitted by Real-time Transport Protocol to the first monitor terminal, first monitor terminal receives the unshielding stream of video data and first encapsulated by Real-time Transport Protocol and blocks stream of video data, and unshielding video data bitstream is parsed respectively Flow and block stream of video data and show that unshielding video data and first blocks video data and Slow has decoder Slow and rushes area respectively, according to the synchronous frame data of synchronized timestamp, unshielding video data and first is extracted respectively blocks the frame data in video data with identical time stamp, the frame data and first for the unshielding video data with identical time stamp that decoding is extracted block the frame data of video data to generate corresponding yuv data respectively, then block video data according to the description information of the first occlusion area synthesis first
The yuv data of yuv data and unshielding video data, and the yuv data of synthesis is rendered into broadcasting.
It should be noted that, if not starting to receive before step 404, the monitoring frontend sends blocks video data and unshielding video data, then send the request for obtaining video data to the monitoring frontend after step 404, specifically, can the user of first monitor terminal according to the judged result to the monitoring frontend acquisition request of step 406 have permission the video data of acquisition, such as, if user only has authority acquiring unshielding video data, then only ask unshielding video data, if user has permission acquisition, unshielding video data and first blocks video data, then acquisition request unshielding video data and first blocks video data, the monitoring frontend receives the video data that request is generated after the request and returns to the monitor supervision platform.The monitoring frontend generation unshielding video data and the first method for blocking video data are repeated no more with step 403.
Step 407B:The unshielding video data is transmitted to first monitor terminal by the monitor supervision platform；
Step 408B:First monitor terminal plays the unshielding video data received.Example embodiment 2:As shown in fig. 7, monitoring frontend generation unshielding video data and block video data, monitor supervision platform blocks video data by what unshielding video data and user had permission acquisition（I.e. first blocks video data）Monitor terminal is sent to after merging.
The interaction diagrams of the example embodiment 2 of the embodiment of the present invention 1 are introduced with reference to Fig. 8.Step 501-506:With step 401-406, no longer praise and state；
If the judged result of step 506 is yes, step 507A-510A is performed;
If the judged result of step 506 is no, step 507B-508B is performed. Step 507A:With step 407A;
Step 508A:Monitor supervision platform merges the unshielding video data and first and blocks video data；Preferably, the description information of the occlusion area received according to step 401 merges described first and blocks video data and unshielding video data.
Specifically, if described first, which blocks video data, includes video data all the way, decode described first and block video data and draw and block video data frame, decode the unshielding video data and draw unshielding video data frame, the pixel data in video data frame is blocked described in extracting, the pixel data of extraction is added to has the corresponding pixel region of occlusion area described in the unshielding video data frame of identical time stamp generation complete video frame with the video data frame that blocks, and encodes the complete video frame with the video data after being merged.If it by the corresponding video pictures direct coding of the occlusion area is described first to block video data in coding to be, the i.e. described video data frame that blocks only includes the pixel data of the corresponding video pictures of the occlusion area, the pixel data blocked in video data frame is then extracted specifically, blocking all pixels data in video data frame described in extraction；If the corresponding video pictures in de-occlusion region in whole video pictures are blocked into the pixel data of video counts and the pixel data of filling using coding generation described first after the pixel value filling of setting in coding, the pixel data for blocking the corresponding pixel region of the first occlusion area in video data frame is extracted.
If described first, which blocks video data, includes multi-path video data, decode described first and block being drawn per video data all the way in video data and block video data frame per video data all the way, decoding unshielding video data draws unshielding video data frame, extract the pixel data blocked in video data frame with identical time stamp of each road video data, and being added to the pixel data of extraction with the video data frame that blocks there is in the unshielding video data frame of identical time stamp the corresponding pixel region of the occlusion area to generate complete video frame, and the complete video frame is encoded with the video data after being merged.
