Description

TECHNICAL FIELD

Embodiments of the present invention relate to the field of video surveillance, and in particular, to a method, an apparatus, and a system for implementing video mask.

BACKGROUND

In the field of video surveillance, a requirement of protecting personal privacy exists, and therefore mask processing needs to be performed for a video image of a part of an area shot by a camera, so that a common user sees a video picture that does not include the image of a masked part, and the image of the masked part can only be viewed by a user with advanced permission.
In the prior art, encryption processing is performed for image data of a masked part in a video, and the processed video is sent to a monitoring terminal. A user with permission is capable of decrypting the image data of the masked part in the received video to see the complete video, while a user with no permission cannot see the image of the masked part. However, in the prior art, a terminal of the user with no permission is also capable of acquiring the image data of the masked part, and if an abnormal means is used to decrypt the data of the part, the image of the masked part can be seen. This causes a security risk.
The document, WO 2006070249A1 , relates to a video surveillance system which addresses the issue of privacy rights and scrambles regions of interest in a scene in a video scene to protect the privacy of human faces and objects captured by the system. The video surveillance system is configured to identify persons and or objects captured in a region of interest of a video scene by various techniques, such as detecting changes in a scene or by face detection.
The document, US 20100149330A1 , relates to a system and method for operator-side privacy zone masking of surveillance. The system includes a video surveillance camera equipped with a coordinate engine for determining coordinates of a current field of view of the surveillance camera; and a frame encoder for embedding the determined coordinates with video frames of the current field of view.

SUMMARY

Embodiments of the present invention provide a method, an apparatus, and a system for implementing video mask, so as to solve a security risk problem resulting from sending image data of a masked part to terminals of users with different permission in the prior art.
The present invention is defined in the attached claims.

The peripheral unit 110 is configured to collect video data and send the collected video data to the monitoring platform through the transmission network. Preferably, the peripheral unit 110 may generate, according to set description information of a masked area, non-masked video data corresponding to a non-masked area and masked video data corresponding to the masked area and separately transmit them to the monitoring platform. Presentation forms of hardware of the peripheral unit 110 may be all types of camera devices, for example, webcams such as a dome camera, a box camera, and a semi-dome camera, and for another example, an analog camera and an encoder.
The monitoring platform 120 is configured to receive the masked video data and the non-masked video data that are sent by the peripheral unit 110, or obtain masked video data and non-masked video data by separating complete video data received from the peripheral unit 110, and send corresponding video data to the monitoring terminal 130 according to permission of a user of the monitoring terminal. For a user that has permission to acquire the masked video data, the monitoring platform 120 may send the masked video data and the non-masked video data to the monitoring terminal for merging and playing; alternatively, the monitoring platform 120 may merge the masked video data and the non-masked video data and send them to the monitoring terminal for playing.
The monitoring terminal 130 is configured to receive the video data sent by the monitoring platform, and if the received video data includes the non-masked video data and the masked video data, further configured to merge and play the masked video data and the non-masked video data.
FIG. 2 is a schematic flowchart of a method for implementing video mask according to a first embodiment of the present invention.
Step 210: Receive a video request sent by a first monitoring terminal, where the video request includes a device identifier, and video data of a peripheral unit identified by the device identifier includes non-masked video data corresponding to a non-masked area and masked video data corresponding to a masked area.
The masked video data and the non-masked video data may specifically be encoded by using an H.264 format.
The device identifier is used to uniquely identify the peripheral unit, and specifically, it may include an identifier of a camera of the peripheral unit, and may further include an identifier of a cloud mirror of the peripheral unit.
Step 220: Determine whether a user of the first monitoring terminal has permission to acquire first masked video data in the masked video data, where the first masked video data corresponds to a first masked area, and the first masked area includes a part or all of the masked area.
The masked area may specifically include one or more areas, where the area may be rectangular, circular, polygonal, and the like. If one area is included, the masked video data corresponding to the masked area may specifically include one channel of video data. If multiple areas are included, the masked video data corresponding to the masked area may specifically include one channel of video data, or may include multiple channels of video data, for example, each area included in the masked area corresponds to one channel of video data.
Specifically, description information of the masked area may be used to describe the masked area. The description information of the masked area specifically includes a coordinate of the masked area. For example, when the masked area includes a rectangle, the description information of the masked area may include coordinates of at least three vertexes of the rectangle, or may only include a coordinate of one vertex of the rectangle and a width and a height of the rectangle, for example (x, y, w, h), where x is the horizontal coordinate of the upper left vertex, y is the vertical coordinate of the upper left vertex, w is the width, and h is the height.
Specifically, overall permission control may be performed for the masked video data, that is, permission to access the masked video data is classified into two permission levels: having access permission and having no access permission. In this case, it can be directly determined whether a user has permission to access the masked video data. According to the implementation manner, the first masked video data is the masked video data, and the first masked area is the masked area (that is, the whole area of the masked area is included). Specifically, area-based permission control may also be performed for the masked video data. Respective permission is set for different areas, that is, video data that corresponds to different areas may correspond to different permission. For example, the masked area includes three areas, area 1 and area 2 correspond to permission A, and area 3 corresponds to permission B. For another example, the masked area includes three areas, area 1 corresponds to permission A, area 2 corresponds to permission B, and area 3 corresponds to permission C. In this case, it needs to determine whether the user has permission to access masked video data that corresponds to a specific area.
Specifically, the permission may be determined according to a password. For example, if a password that is received from the first monitoring terminal and used to acquire the first masked video data is determined to be correct (that is, a user inputs a correct password), it is determined that the user has the permission to acquire the first masked video data.
Specifically, the permission may be further determined according to a user identifier of a user of the first monitoring terminal. For example, an authorized user identifier may be preconfigured, and if the user identifier matches the authorized user identifier, it is determined that the user has the permission to acquire the first masked video data; an authorized account type may also be preconfigured, and if an account type corresponding to the user identifier matches the authorized account type, it is determined that the user has the permission to acquire the first masked video data. Optionally, the user identifier may be acquired during login of the user performed by using the monitoring terminal. In addition, the video request received in step 210 may carry the user identifier, and in this case, the user identifier carried in the video request may be acquired.
If a determined result is yes, perform step 230A. If the determined result is no, perform step 230B.
Step 230A: Acquire the first masked video data and the non-masked video data; and send the first masked video data and the non-masked video data to the first monitoring terminal, so that the first monitoring terminal merges and plays the first masked video data and the non-masked video data, or merge the first masked video data and the non-masked video data and send the merged video data to the first monitoring terminal.
Preferably, a data type of the masked video data may also be sent to the first monitoring terminal, so that the first monitoring terminal identifies the masked video data from the received video data. Specifically, the data type may specifically be included in an acquiring address (for example, a URL) that is sent to the first monitoring terminal and used to acquire the masked video data, or the data type may be included in a message that is sent to the first monitoring terminal and used to carry the acquiring address, or the data type may be sent in a process of establishing a media channel between the first monitoring terminal and a monitoring platform, where the media channel is used to transmit the masked video data.
Preferably, before the sending the first masked video data, the method may further include: sending description information of the first masked area to the first monitoring terminal, so that the first monitoring terminal merges and plays, according to the description information of the first masked area, the first masked video data and the non-masked video data that are received in step 230A. Specifically, the description information may be included in the acquiring address (for example, a URL) that is sent to the first monitoring terminal and used to acquire the masked video data, or the description information may be included in the message that is sent to the first monitoring terminal and used to carry the acquiring address, or the description information may be sent in the process of establishing the media channel used to transmit the masked video data.
Step 230B: Acquire the non-masked video data and send it to the first monitoring terminal. Optionally, specific implementations of step 230A and step 230B are as follows:

In step 230A, the acquiring the first masked video data and the non-masked video data; and sending the first masked video data and the non-masked video data to the first monitoring terminal may specifically include: generating an acquiring address (for example, a URL, acquiring address 1 for short below) of the first masked video data and an acquiring address (for example, a URL, acquiring address 2 for short below) of the non-masked video data and sending the acquiring addresses to the first monitoring terminal, receiving a request that is sent by the first monitoring terminal and includes the acquiring address 2, establishing, with the first monitoring terminal according to the acquiring address 2, a media channel used to send the non-masked video data, acquiring the non-masked video data according to the acquiring address 2, and sending the non-masked video data through the media channel; meanwhile, receiving a request that is sent by the first monitoring terminal and includes the acquiring address 1, establishing, with the first monitoring terminal according to the acquiring address 1, a media channel used to send the first masked video data, acquiring the first masked video data according to the acquiring address of the first masked video data, and sending the first masked video data through the media channel. Specifically, if the first masked video data includes multiple channels of video data, the acquiring address of the first masked video data includes acquiring addresses of the multiple channels of video data, and media channels established subsequently include multiple media channels used to transmit the multiple channels of video data.

Preferably, the acquiring address (for example, a URL) sent to the first monitoring terminal carries a data type. The data type is used to indicate that the video data that can be acquired according to the acquiring address is the non-masked video data or the masked video data. Examples of a format of a URL (universal resource locator, Universal Resource Locator) that carries the data type are as follows:

an example of a URL of the non-masked video data: rtsp://192.7.90.55:554/ipc00001?type=non-masked; and
an example of a URL of the masked video data: rtsp://192.7.90.55:554/ipc00001?type=masked;
where rtsp refers to the Real-Time Streaming Protocol.

Preferably, description information (for example, a coordinate of a masked area) of the masked area corresponding to the masked video data may be further carried in the acquiring address of the masked video data. Examples of a format of a URL that carries the data type and the description information of the masked area are as follows:

example 1 of the URL of the masked video data: rtsp://192.7.90.55:554/ipc00001?type=masked&masked coordinate 1 (x1, y1, w1, h1)&masked coordinate 2 (x2, y2, w2, h2), where in this example, the masked video data corresponds to two masked areas; and
example 2 of the URL of the masked video data: rtsp://192.7.90.55:554/ipc00001?type=masked&masked coordinate 1 (x1, y1, w1, h1), where in this example, the masked video data corresponds to one masked area.

Optionally, the monitoring platform may further send the data type and/or the description information of the masked area to the first monitoring terminal by message exchange. For example, when a URL is returned to the first monitoring terminal, the data type and/or the description information of the masked area is included in a message body of an XML structure in a message that carries the URL, as shown in the following:

           <url> rtsp://192.7.90.55:554/ipc00001?type=masked</url>
           <coordinate>
           <value>(x1,y1,w1,h1)</value>
           <value>(x2,y2,w2,h2)</value>
           <coordinate>

In addition, a user-defined structure body in an RTSP ANNOUNCE message may also be used to carry the data type and/or the description information of the masked area in the process of establishing the media channel between the first monitoring terminal and the monitoring platform. An example is shown as follows:

           S->C: ANNOUNCE rtsp://192.7.90.55:554/ipc00001 RTSP/1.0
           CSeq: 312

           Session: 47112344
           urltype: KeepOutUrl // indicating that the media stream belongs to the masked video
 data
           urlcoordinate:x1=100,y1=100,w1=200,h1=200;x2=100,y2=100,w2=200,h2=200.

In step 230A, the acquiring the first masked video data and the non-masked video data, merging the first masked video data and the non-masked video data, and sending the merged video data to the first monitoring terminal specifically includes: generating an acquiring address (for example, a URL) used to acquire the merged video data and sending it to the first monitoring terminal, receiving a request that is sent by the first monitoring terminal and includes the acquiring address, establishing, with the first monitoring terminal according to the acquiring address, a media channel used to send the merged video data, acquiring and merging the first masked video data and the non-masked video data, and sending the merged video data to the first monitoring terminal through the media channel.

Step 230B may include: generating an acquiring address of the non-masked video data and sending it to the first monitoring terminal, receiving a request that is sent by the first monitoring terminal and includes the acquiring address, establishing, with the first monitoring terminal according to the acquiring address, a media channel used to send the non-masked video data, acquiring the non-masked video data according to the acquiring address of the non-masked video data and sending the non-masked video data through the media channel.

The following describes an optional implementation manner of the first embodiment of the present invention with reference to FIG. 3.

A CU (Client Unit, client unit) in this implementation manner is client software installed on a monitoring terminal and provides monitoring personnel with functions such as real-time video surveillance, video query and playback, and a cloud mirror operation.

A monitoring platform includes an SCU (Service Control Unit, service control unit) and an MU (Media Unit, media unit). In a practical application, the SCU and the MU may be implemented in a same universal server or dedicated server, or may be separately implemented in different universal servers or dedicated servers.

Step 301: A CU sends a video request to an SCU of a monitoring platform, where the video request includes a device identifier and is used to request video data of a peripheral unit identified by the device identifier, and the video data includes non-masked video data corresponding to a non-masked area and masked video data corresponding to a masked area.

Step 302: The SCU determines whether a user of the CU has permission to acquire first masked video data in the masked video data, where the first masked video data corresponds to a first masked area, and the first masked area includes a part or all of the masked area.

Specific implementation of step 302 is the same as that of step 220, and therefore no further details are provided herein.

If a determined result is yes, steps 303A-312A are performed. In this implementation manner, it is assumed that the first masked video data includes one channel of video data.

If the determined result is no, steps 303B-308B are performed.

Steps 303A-306A: The SCU requests a URL of the first masked video data and a URL of the non-masked video data from an MU, and the MU generates the URL of the first masked video data and the URL of the non-masked video data and returns them to the SCU.

Step 307A: The SCU returns the URL of the first masked video data and the URL of the non-masked video data to the CU.

Steps 308A-309A: The CU requests the first masked video data from the MU according to the URL of the first masked video data, establishes, with the MU, a media channel used to transmit the first masked video data, and receives, through the media channel, the first masked video data sent by the MU.

Steps 310A-311A: The CU requests the non-masked video data from the MU according to the URL of the non-masked video data, establishes, with the MU, a media channel used to transmit the non-masked video data, and receives, through the media channel, the non-masked video data sent by the MU.

Step 312A: The CU merges and plays the first masked video data and the non-masked video data. Steps 303B-304B: The SCU requests a URL of the non-masked video data from the MU, and the MU generates the URL of the non-masked video data and returns it to the SCU.

Step 305B: The SCU returns the URL of the non-masked video data to the CU.

Steps 306B-307B: The CU requests the non-masked video data from the MU according to the URL of the non-masked video data, establishes, with the MU, a media channel used to transmit the non-masked video data, and receives, through the media channel, the non-masked video data sent by the MU.

Step 308B: The CU plays the non-masked video data.

According to the first embodiment of the present invention, after receiving a video request of a monitoring terminal, a monitoring platform determines permission of a user of the monitoring terminal, sends, according to a determined result, only non-masked video data to a monitoring terminal of a user that has no permission to acquire masked video data, and sends the masked video data and the non-masked video data to a monitoring terminal of a user that has permission to acquire a part or all of the masked video data, so that the monitoring terminal merges and plays the masked video data and the non-masked video data, or sends video data merged from the masked video data and the non-masked video data, thereby solving a security risk problem resulting from sending image data of a masked part to terminals of users with different permission in the prior art. In addition, according to the first embodiment of the present invention, area-based permission control may be implemented, that is, if the masked area includes multiple areas, permission may be set for each different area, and masked video data that corresponds to a part or all of an area and that a user has permission to acquire is sent to a monitoring terminal of the user according to the permission of the user, thereby implementing more accurate permission control.

It should be noted that the first embodiment of the present invention not only can be used in a real-time video surveillance scenario, but also can be used in a video view scenario (for example, video playback and video downloading). If the first embodiment is used in the video view scenario, the acquiring non-masked video data in

steps

230A and 230B is specifically reading the non-masked video data from a non-masked video file, and the acquiring masked video data in step 230A is specifically reading masked video data from a masked video file.

Correspondingly, before step 210, the following operations are performed:

Store the masked video data into the masked video file, store the non-masked video data into the non-masked video file, and establish an association between the masked video file and the non-masked video file, where the masked video file includes one or more video files.

The establishing an association between the masked video file and the non-masked video file specifically includes: recording a non-masked video index and a masked video index, and establishing an association between the non-masked video index and the masked video index, where the non-masked video index includes a device identifier of the peripheral unit, video start time and end time, indication information of the non-masked video data, and an identifier of the non-masked video file (for example, a storage address of the non-masked video file, which may specifically be an absolute path of the non-masked video file), and the indication information of the non-masked video data is used to indicate that the non-masked video index is an index of the non-masked video file; and the masked video index includes indication information of the masked video data and an identifier of the masked video file (for example, a storage address of the masked video file, which may specifically be an absolute path of the masked video file), and the indication information of the masked video data is used to indicate that the masked video index is an index of the masked video file. Preferably, both the non-masked video index and the masked video index may include indication information of a non-independent index, where the indication information of the non-independent index is used to indicate an index associated with the index. For example, the indication information of the non-independent index of the non-masked video index is used to indicate a masked video index associated with the non-masked video index. The non-masked video index and/or the masked video index may further include description information of a masked area, or information (for example, a storage address of the description information of the masked area) used to acquire the description information of the masked area. The establishing an association between the non-masked video index and the masked video index may specifically include recording an identifier (for example, an index number) of the masked video index into the non-masked video index, or may further include recording an identifier (for example, an index number) of the non-masked video index into the masked video index, or may further include recording an association between the identifier of the masked video index and the identifier of the non-masked video index. It should be noted that if the masked video data includes multiple channels of video data, a masked video index may be established for each channel of video data, and an association is established between the non-masked video index and each masked video index.

Preferably, description information of a masked area corresponding to the video file, or information used to acquire the description information of the masked area corresponding to the video file is recorded in each masked video index.

Examples of the non-masked video index and the masked video index are shown in Table 1.

Correspondingly, if the first embodiment is used in the video view scenario, the video request sent in step 210 may further include view time. In

steps

230A and 230B, the acquiring the non-masked video data is specifically acquiring video data corresponding to the view time from the non-masked video file, and may specifically include: acquiring the non-masked video index according to the identifier of the peripheral unit, the view time, and the indication information of the non-masked video data, acquiring the non-masked video file according to the identifier of the non-masked video file in the non-masked video index, and acquiring the non-masked video data corresponding to the view time from the non-masked video file. In step 230A, the acquiring the masked video data is specifically acquiring, according to the association between the masked video file and the non-masked video file, one or more video files that are associated with the non-masked video file and correspond to the first masked area and acquiring the video data corresponding to the view time from the one or more video files corresponding to the first masked area, and specifically includes: acquiring, according to the association between the non-masked video index and the masked video index (for example, according to the identifier of the masked video index in the non-masked video index), the masked video index associated with the non-masked video index, acquiring, according to the identifier of the masked video file included in the masked video index, one or more video files corresponding to the first masked area, and acquiring the video data corresponding to the view time from the one or more video files corresponding to the first masked area. Preferably, before the acquiring, according to the association, the masked video index associated with the non-masked video index, the masked video index associated with the non-masked video index may be further determined according to the indication information of the non-independent index in the non-masked video index, so as to improve efficiency of the monitoring platform in retrieving the masked video index.

Specifically, after the non-masked video index is acquired, an acquiring address used to acquire the non-masked video data may be generated according to the non-masked video index and sent to a first monitoring terminal, a request that is sent by the first monitoring terminal and includes the acquiring address of the non-masked video data is received, a media channel used to send the non-masked video data is established with the first monitoring terminal according to the acquiring address of the non-masked video data, the non-masked video data is acquired according to the acquiring address of the non-masked video data, and the non-masked video data is sent through the media channel. For example, as shown in FIG. 3, the SCU of the monitoring platform acquires the non-masked video index after receiving the video request, requests, from the MU according to the non-masked video index, a URL used to acquire the non-masked video data corresponding to the non-masked video index, and sends the URL to the CU. The MU receives the request that is sent by the CU and includes the URL, establishes, with the CU according to the URL, a media channel used to send the non-masked video data, reads the non-masked video data in the video file according to the URL, and sends the non-masked video data to the CU through the media channel. A process of sending the masked video data after the masked video index is acquired is similar to a process of sending the non-masked video data after the non-masked video index is acquired, and therefore no further details are provided herein.

Preferably, before the sending the first masked video data, the method may further include: sending description information of the first masked area to the first monitoring terminal, so that the first monitoring terminal merges and plays, according to the description information of the first masked area, the first masked video data and the non-masked video data that are received in step 230A. The method may specifically include: acquiring the non-masked video index or description information of a masked area that is included in a masked video index corresponding to the first masked video data, or acquiring the description information of the first masked area according to the non-masked video index or information that is included in the masked video index and used to acquire the description information of the first masked area, and sending the acquired description information of the first masked area to the first monitoring terminal. Specifically, the description information of the first masked area may be carried in a message that is sent to the first monitoring terminal and carries an acquiring address of the first masked video data.

Preferably, before step 230A, the method further includes receiving a masked area setting request sent by a second monitoring terminal, where the masked area setting request includes a device identifier of the peripheral unit and the description information of the masked area. After the masked area setting request is received, the description information of the masked area may be sent to the peripheral unit, and the non-masked video data and the masked video data that are sent by the peripheral unit and generated according to the description information of the masked area are received; or the masked video data and the non-masked video data may be obtained by separating, according to the description information of the masked area, complete video data received from the peripheral unit. In addition, as described in step 230A, the masked video data and the non-masked video data may be sent to the first monitoring terminal and be merged and played by the first monitoring terminal, or the masked video data and the non-masked video data may be merged and then sent to the first monitoring terminal.

It should be noted that the first monitoring terminal and the second monitoring terminal may be a same monitoring terminal.

In conclusion, an entity generating the non-masked video data and the masked video data may be a peripheral unit or a monitoring platform, and an entity merging the non-masked video data and the masked video data may be a monitoring platform or a monitoring terminal (that is, the first monitoring terminal in the first embodiment of the present invention). According to different entities performing a generation operation and a merging operation, the following separately describes three exemplary implementation manners of the first embodiment of the present invention.

A first exemplary implementation manner is as follows: As shown in FIG. 4, the peripheral unit generates the non-masked video data and the masked video data, the monitoring platform separately sends the monitoring terminal (for example, the first monitoring terminal in this embodiment) the non-masked video data and the masked video data (for example, the first masked video data in this embodiment) that a user has permission to acquire, and the monitoring terminal merges and plays the received video data.

The following introduces an exchange flowchart of the first exemplary implementation manner according to the first embodiment of the present invention with reference to FIG. 5.

Step 401: A second monitoring terminal sends a masked area setting request to a monitoring platform, where the masked area setting request includes a device identifier and description information of a masked area.

The masked area may specifically include one or more areas, where the area may be rectangular, circular, polygonal, and the like. Preferably, the description information of the masked area specifically includes a coordinate of the masked area. For example, when the masked area includes a rectangle, the description information of the masked area may include coordinates of at least three vertexes of the rectangle, or may only include a coordinate of one vertex of the rectangle and a width and a height of the rectangle, for example (x, y, w, h), where x is the horizontal coordinate of the upper left vertex, y is the vertical coordinate of the upper left vertex, w is the width, and h is the height.

Step 402: The monitoring platform sends the masked area setting request to a peripheral unit identified by the device identifier, where the masked area setting request includes the description information of the masked area.

Step 403: The peripheral unit encodes a captured video picture to generate masked video data and non-masked video data.

Specifically, the peripheral unit encodes the captured video picture into the non-masked video data corresponding to a non-masked area and the masked video data corresponding to the masked area. If the masked area includes one area, a video picture corresponding to the masked area may be encoded into one channel of video data, that is, the masked video data includes one channel of video data.

If the masked area includes multiple areas, video pictures corresponding to the multiple areas included in the masked area may be encoded into one channel of video data, that is, the masked video data includes one channel of video data; or video pictures corresponding to the multiple areas included in the masked area may be encoded into one channel of video data each, that is, the masked video data includes multiple channels of video data and each area corresponds to one channel of video data; or video pictures corresponding to areas with same permission among the multiple areas included in the masked area may be encoded into one channel of video data, that is, the areas corresponding to the same permission correspond to a same channel of video data, for example, if the masked area includes three areas, area 1 and area 2 correspond to same permission, and area 3 corresponds to another permission, video pictures corresponding to area 1 and area 2 are encoded into a same channel of video data, and a video picture corresponding to area 3 is encoded into another channel of video data.

Specifically, the video picture corresponding to the masked area may be directly encoded into the masked video data, that is, a video data frame of the masked video data includes only pixel data of the video picture corresponding to the masked area; or a video picture in the whole captured video picture may be encoded after filling the video picture by using a set pixel value so as to generate the masked video data, where the video picture corresponds to the non-masked area, that is, a video data frame of the non-masked video data includes both pixel data of the video picture corresponding to the masked area and filled pixel data.

Encoding formats include but are not limited to H.264, MPEG4, and MJPEG, and the like.

Specifically, the video picture corresponding to the non-masked area may be directly encoded into the non-masked video data, or the video picture in the whole captured video picture may be encoded after filling the video picture by using a set pixel value so as to generate the non-masked video data, where the video picture corresponds to the masked area, and the set pixel value is preferably RGB (0, 0, 0).

During the encoding, timestamps of video data frames corresponding to a same complete video picture are kept completely consistent in the masked video data and the non-masked video data.

It should be noted that in the first exemplary implementation manner, the description information of the masked area is sent by the monitoring platform to the peripheral unit. Optionally, the description information of the masked area may be preset on the peripheral unit.

Step 404: Send the generated masked video data and non-masked video data to the monitoring platform.

Preferably, the peripheral unit may further send a data type of the masked video data to the monitoring platform, so that the monitoring platform identifies the masked video data from received video data. The data type may be specifically included in an acquiring address (for example, a URL) that is sent to the monitoring platform and used to acquire the masked video data (where the monitoring platform may acquire the masked video data from the peripheral unit by using the acquiring address), or the data type may be included in a message that is sent to the monitoring platform and used to carry the acquiring address, or the data type may be sent in a process of establishing a media channel between the monitoring platform and the peripheral unit and used to transmit the masked video data.

Step 405: A first monitoring terminal sends a video request to the monitoring platform, where the video request includes the device identifier of the peripheral unit.

Step 406: Determine whether a user of the first monitoring terminal has permission to acquire first masked video data in the masked video data, where the first masked video data corresponds to a first masked area, and the first masked area includes a part or all of the masked area.

If a determined result is yes, steps 407A-409A are performed.

If the determined result is no, steps 407B-408B are performed.

Step 407A: The monitoring platform sends description information of the first masked area to the first monitoring terminal.

Step 408A: The monitoring platform sends the first masked video data and the non-masked video data to the first monitoring terminal.

Step 409A: The first monitoring terminal merges and plays the received first masked video data and non-masked video data.

Preferably, the received first masked video data and non-masked video data are merged and played according to the description information of the first masked area.

Specifically, if the first masked video data includes one channel of video data, the first masked video data is decoded to obtain a masked video data frame, the non-masked video data is decoded to obtain a non-masked video data frame, pixel data in the masked video data frame is extracted, the extracted pixel data is added, according to the description information of the first masked area, to a pixel area in a non-masked video data frame that has a same timestamp as the masked video data frame so as to generate a complete video data frame, where the pixel area corresponds to the first masked area, and the complete video data frame is played. If a video picture corresponding to the first masked area is directly encoded into the first masked video data during encoding, that is, the masked video data frame includes only pixel data of a video picture corresponding to the masked area, the extracting the pixel data in the masked video data frame is specifically extracting all pixel data in the masked video data frame. If a video picture in the whole captured video picture is encoded after filling the video picture by using a set pixel value so as to generate the masked video data during the encoding, where the video picture corresponds to the non-masked area, that is, a video data frame of the non-masked video data includes both the pixel data of the video picture corresponding to the masked area and the filled pixel data, pixel data of the pixel area in the masked video data frame is extracted according to the description information of the first masked area, where the pixel area corresponds to the first masked area.

If the first masked video data includes multiple channels of video data, each channel of video data in the first masked video data is decoded to obtain a masked video data frame of the channel of video data, the non-masked video data is decoded to obtain a non-masked video data frame, pixel data in masked video data frames of all channels of video data is extracted, where the masked video data frames have a same timestamp, the extracted pixel data is added to a pixel area in a non-masked video data frame that has the same timestamp as the masked video data frames so as to generate a complete video data frame, where the pixel area corresponds to the first masked area, and the complete video data frame is played.

Specifically, as shown in FIG. 6, both the non-masked video data and the first masked video data are transmitted to the first monitoring terminal through the RTP protocol. The first monitoring terminal receives a non-masked video data code stream and a first masked video data code stream that are encapsulated through the RTP protocol, parses the non-masked video data code stream and the first masked video data code stream to obtain the non-masked video data and the first masked video data respectively, and separately caches the non-masked video data and the first masked video data in a decoder buffer area. Frame data is synchronized according to a synchronization timestamp, that is, frame data that has a same timestamp is separately extracted from the non-masked video data and the first masked video data. The extracted frame data of the non-masked video data and the extracted frame data of the first masked video data that have the same timestamp are separately encoded to generate corresponding YUV data. Then, YUV data of the first masked video data and YUV data of the non-masked video data are merged according to the description information of the first masked area, and the merged YUV data is rendered and played.

It should be noted that if the masked video data and the non-masked video data that are sent by the peripheral unit are not received before step 404, a request for acquiring video data is sent to the peripheral unit after step 404. Specifically, video data that a user of the first monitoring terminal has permission to acquire may be requested from the peripheral unit according to the determined result in step 406. For example, if the user only has permission to acquire the non-masked video data, only the non-masked video data is requested; and if the user has permission to acquire the non-masked video data and the first masked video data, the non-masked video data and the first masked video data is requested. After receiving the request, the peripheral unit generates the requested video data and returns it to the monitoring platform. A method used by the peripheral unit to generate the non-masked video data and the first masked video data is the same as that in step 403, and therefore no further details are provided.

Step 407B: The monitoring platform forwards the non-masked video data to the first monitoring terminal.

Step 408B: The first monitoring terminal plays the received non-masked video data.

A second exemplary implementation manner 2 is as follows: As shown in FIG. 7, the peripheral unit generates the non-masked video data and the masked video data, and the monitoring platform merges the non-masked video data and the masked video data (that is, the first masked video data) that a user has permission to acquire and then sends them to the monitoring terminal.

The following introduces an exchange flowchart of the second exemplary implementation manner according to the first embodiment of the present invention with reference to FIG. 8.

Steps 501-506 are the same as steps 401-406, and therefore no further details are provided.

If a determined result in step 506 is yes, steps 507A-510A are performed.

If the determined result in step 506 is no, steps 507B-508B are performed.

Step 507A is the same as step 407A.

Step 508A: The monitoring platform merges the non-masked video data and the first masked video data.

Preferably, the first masked video data and the non-masked video data are merged according to the description information of the masked area received in step 501.

Specifically, if the first masked video data includes one channel of video data, the first masked video data is decoded to obtain a masked video data frame, the non-masked video data is decoded to obtain a non-masked video data frame, pixel data in the masked video data frame is extracted, the extracted pixel data is added to a pixel area in a non-masked video data frame that has the same timestamp as the masked video data frames so as to generate a complete video data frame, where the pixel area corresponds to the masked area, and the complete video data frame is encoded to obtain the merged video data. If a video picture corresponding to the masked area is directly encoded into the first masked video data during encoding, that is, the masked video data frame includes only pixel data of the video picture corresponding to the masked area, the extracting the pixel data in the masked video data frame is specifically extracting all pixel data in the masked video data frame. If a video picture in the whole captured video picture is encoded after filling the video picture by using a set pixel value so as to generate the first masked video data during the encoding, where the video picture corresponds to the non-masked area, that is, a video data frame of the non-masked video data includes both the pixel data of the video picture corresponding to the masked area and the filled pixel data, pixel data of a pixel area in the masked video data frame is extracted, where the pixel area corresponds to the first masked area.

If the first masked video data includes multiple channels of video data, each channel of video data in the first masked video data is decoded to obtain a masked video data frame of the channel of video data, the non-masked video data is decoded to obtain a non-masked video data frame, pixel data in masked video data frames of all channels of video data is extracted, where the masked video data frames have a same timestamp, the extracted pixel data is added to a pixel area in a non-masked video data frame that has the same timestamp as the masked video data frames so as to generate a complete video data frame, where the pixel area corresponds to the masked area, and the complete video data frame is encoded to obtain the merged video data.

Specifically, as shown in FIG. 9, both the non-masked video data and the first masked video data are transmitted to the monitoring platform through the RTP protocol. Processing after the monitoring platform receives a non-masked video data code stream and a first masked video data code stream that are encapsulated through the RTP protocol is similar to the processing after the first monitoring terminal receives a code stream in step 409A. A difference lies only in that the first monitoring terminal renders and plays YUV data after merging the YUV data, while the monitoring platform encodes merged YUV data after merging the YUV data, so as to generate the merged video data.

Step 509A: Send the merged video data to the first monitoring terminal.

Step 510A: The first monitoring terminal directly decodes and plays the merged video data.

Steps 507B-508B are the same as steps 407B-408B.

A third exemplary implementation manner is as follows: As shown in FIG. 10, the peripheral unit generates complete video data, the monitoring platform obtains the masked video data and the non-masked video data by separating the complete video data received from the peripheral unit, and separately sends the monitoring terminal the non-masked video data and the masked video data that a user has permission to acquire, and the monitoring terminal merges and plays the received masked video data and non-masked video data.

The following introduces an exchange flowchart of the third exemplary implementation manner according to the first embodiment of the present invention with reference to FIG. 11.

Step 601 is the same as step 401, and therefore no further details are provided.

Step 602: The peripheral unit encodes a captured video picture into complete video data and sends the complete video data to the monitoring platform.

Step 603: The monitoring platform obtains the masked video data corresponding to a masked area and the non-masked video data corresponding to a non-masked area by separating, according to the description information of a masked area received in step 601, the complete video data.

If the masked area includes one area, a video picture in the complete video data may be encoded into one channel of video data, that is, the masked video data includes one channel of video data, where the video picture corresponds to the masked area.

If the masked area includes multiple areas, video pictures in the complete video data that correspond to the multiple areas included in the masked area may be encoded into one channel of video data, that is, the masked video data includes one channel of video data; or video pictures in the complete video data that correspond to the multiple areas included in the masked area may be encoded into one channel of video data each, that is, the masked video data includes multiple channels of video data and each area corresponds to one channel of video data; or video pictures corresponding to areas with same permission among the multiple areas included in the masked area may be encoded into one channel of video data, that is, the areas corresponding to the same permission correspond to a same channel of video data, for example, if the masked area includes three areas, area 1 and area 2 correspond to same permission, and area 3 corresponds to another permission, video pictures corresponding to area 1 and area 2 are encoded into a same channel of video data, and a video picture corresponding to area 3 is encoded into another channel of video data.

Specifically, the video picture corresponding to the masked area may be directly encoded into the masked video data. This includes: decoding the complete video data to obtain a complete video data frame and extracting pixel data of the video picture in the complete video data frame to generate a video data frame of the masked video data, where the video picture corresponds to the masked area. A video picture in the whole captured video picture may also be encoded after filling the video picture by using a set pixel value so as to generate the masked video data, where the video picture corresponds to the non-masked area. This includes: decoding the complete video data to obtain a complete video data frame and setting a pixel value of a pixel of a pixel area in the complete video data frame as a set pixel value, where the pixel area corresponds to the non-masked area, that is, the video data frame of the non-masked video data includes both the pixel data of the video picture corresponding to the masked area and the filled pixel data.

The obtaining the non-masked video data corresponding to a non-masked area may specifically be directly encoding the video picture corresponding to the non-masked area into the non-masked video data, which includes decoding the complete video data to obtain a complete video data frame and extracting pixel data of the video picture in the complete video data frame to generate the video data frame of the non-masked video data, where the video picture corresponds to the non-masked area; or may specifically be encoding the video picture in the whole video picture after filing the video picture by using a set pixel value so as to generate the non-masked video data, where the video picture corresponds to the masked area, which includes: decoding the complete video data to obtain a complete video data frame and setting a pixel value of a pixel of a pixel area in the complete video data frame as the set pixel value, where the pixel area corresponds to the masked area, and the set pixel value is preferably RGB (0, 0, 0).

During the encoding, timestamps of video data frames corresponding to a same complete video picture are kept completely consistent in the masked video data and the non-masked video data. Encoding formats include but are not limited to H.264, MPEG4, and MJPEG.

Steps 604-605 are the same as steps 405-406.

If a determined result in step 605 is yes, steps 606A-608A are performed.

If the determined result in step 605 is no, steps 606B-607B are performed.

Steps 606A-608A are the same as steps 407A-409A.

Steps 606B-607B are the same as steps 407B-408B.
