These platforms need to access the camera footage from the port security project and request that each unit and department add its own OSD tag to the video.

This invention enables the full reuse of cameras in the construction of port area security systems. When multiple higher-level departments access the same video feed, each feed has its own unique OSD tag, which can avoid the duplication of cameras in the same location.

[0063] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, and in order to make the above and other objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention are described below.

[0069] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0070] With the development of smart ports, the construction of smart port security has received attention from all levels of units and departments. Due to the sensitivity of port security systems, especially the monitoring video of important locations such as port customs and border inspection, they have attracted the attention of multiple departments. Due to spatial location and cost constraints, it is not possible to deploy cameras in the same location for each unit to use individually. Therefore, it is necessary to reuse a single camera so that all units can access it simultaneously, and add a unique OSD tag to each unit's video stream. To address this problem, the inventor conceived of fully reusing cameras in the construction of port security systems, with each superior department overlaying its own unique OSD tag when accessing the same video feed.

[0071] To address this, this invention provides a method for displaying video differentiation symbols. This method enables the full reuse of cameras in port area security system construction. When multiple higher-level departments access the same video feed, each feed carries its own unique OSD tag, avoiding the duplication of camera deployments in the same location. The specific execution steps are as follows: Figure 1 As shown, it includes:

[0072] 101. Obtain the decoded target video stream.

[0073] This invention provides a video differentiation symbol display method based on a single-camera, multi-user multiplexed OSD display system. The display system includes a video access section, a video processing section, and a video management section. The video access section can be multiple video surveillance platforms already established at the port, such as the Hikvision 8600 platform, Huawei IVS3800 platform, etc., without specific limitations in this step. The display system retrieves the target video stream from the multiple video surveillance platforms already established at the port based on instructions sent by various superior units and departments. The video processing section processes the video stream data retrieved from the video access section through secondary encoding and outputs it to the superior units and departments. The video management section integrates resource management, multi-level permission management, OSD overlay management, system operation control management, database management, and information publishing management of the display system, without specific limitations in this step.

[0074] The target video stream is the video from surveillance cameras that each superior unit and department needs to access; the decoded target video stream is the video stream data obtained by decoding the target video stream accessed through the video access part based on the access instructions of each superior unit and department.

[0075] 102. Superimpose the target symbol onto the decoded target video stream to obtain a video stream with superimposed target symbol.

[0076] According to step 101, the decoded target video stream is obtained. Target symbols are then superimposed on the decoded target video stream using OSD overlay management to obtain the overlaid target symbol video stream. The target symbols are exclusive symbols of the superior units and departments that need to retrieve the target video stream. These superior units and departments can be public security, customs, border inspection, emergency response, maritime affairs, port groups, etc. The target symbols can be graphic symbols, names, abbreviations, or mixed symbols of graphics and names of the units and departments, etc. This step does not impose specific limitations. For example, when a customs unit retrieves port surveillance video, the surveillance video displayed on the client side of the customs platform contains customs graphic symbols.

[0077] 103. Encode the video stream with the superimposed target symbol and send it to the target video playback platform corresponding to the target symbol.

[0078] According to step 102, the superimposed target symbol video stream is obtained. The superimposed target symbol video stream is then encoded. The encoding method can be the ITU's H.261 or H.263 encoding / decoding standards, which are not specifically limited in this step. The target symbol can be obtained from the superimposed target symbol video stream. Based on the target symbol, the corresponding target video playback platform can be obtained through a preset mapping table. The target video playback platform is the video playback platform corresponding to the target video playback client that sends the command to retrieve the target video stream to the display system. The target video playback platform can be a customs platform, a border inspection platform, etc., and the target video playback client is the terminal using the target video playback platform, such as a customs platform and a corresponding monitoring terminal. This step is not specifically limited in this step.

[0079] 104. The target video playback platform receives and decodes the encoded video stream overlaid with target symbols.

[0080] The decoding method can be the ITU-T H.261 or H.263 encoding / decoding standards; this step is not specifically limited. The target video playback platform receives the encoded video stream with superimposed target symbols sent by the video processing unit, decodes it, and stores it in the target video playback platform for playback and display by the target video playback client corresponding to the target video playback platform.

[0081] 105. The target video playback client corresponding to the target video playback platform plays the video stream with the target symbol superimposed.

[0082] The target video playback client is a client that retrieves the video stream with superimposed target symbols through the target video playback platform; for example, the target video playback platform is a border inspection platform, and the target video playback client is a computer terminal of a department of a border inspection agency; the retrieved video stream with superimposed target symbols is a monitoring screen of a certain location in a port, and the upper left corner of the monitoring screen has the abbreviation "border inspection" of the border inspection agency.

[0083] Based on the above Figure 1 As can be seen from the implementation of the embodiments, this invention provides a method for displaying differentiated video symbols. When video surveillance platforms of higher-level units and departments access camera footage from port security projects, they wish to add OSD tags specific to each unit and department to the video. However, in the existing technology, there are no precedents or technologies for this application, and due to environmental factors on-site, it is impossible to install multiple cameras in the same location for different higher-level units and departments to access. To address this, this invention obtains a decoded target video stream; superimposes target symbols onto the decoded target video stream to obtain a superimposed target symbol video stream; encodes the superimposed target symbol video stream and sends it to the target video playback platform corresponding to the target symbol; the target video playback platform receives and decodes the encoded superimposed target symbol video stream; and the target video playback client corresponding to the target video playback platform plays the superimposed target symbol video stream. Therefore, this invention enables the full reuse of cameras in port security system construction, allowing multiple higher-level departments to access the same video feed with their own unique OSD tags, thus avoiding the duplication of camera installations in the same location.

[0084] Furthermore, as a response to Figure 1 Further refinement and extension of the illustrated embodiment, this invention also provides another method for displaying video differentiation symbols, such as... Figure 2 As shown, the specific steps are as follows:

[0085] 201. Determine if the target video stream exists on the currently accessed video playback platform.

[0086] This invention provides a video differentiation symbol display method based on a single-camera, multi-user multiplexing OSD display system. The display system includes a unified management platform, with one GB28181 national standard streaming media gateway configured in each of the north and south directions of the unified management platform, serving as the upper and lower levels respectively for video access and output. This GB28181 national standard streaming media gateway supports simultaneous access and cascading of multiple heterogeneous platforms. It supports interfacing with the upper-level platform using the GB / T28181 and RTMP standards, and accessing the lower-level platform using a proprietary SDK protocol, HTTP, GB / T28181 standard, ONVIF standard, RTSP standard, and RTMP standard. The southbound GB28181 national standard streaming media gateway is specifically responsible for retrieving video streams from the Hikvision 8600 platform via the GB28181 protocol. The northbound GB28181 national standard streaming media gateway is responsible for pushing video streams to multiple different video platforms at the higher level via the GB28181 protocol. It also meets the requirements for east-west access resource management, multi-level permission management, OSD overlay management, system operation control management, database management, and information publishing management. Access function management is performed as needed, and this step does not specify any limitations. Furthermore, the east-west interface "decoding / encoding gateway" handles video calls and concurrent processing. The "decoding / encoding gateway" can concurrently decode 30-60 video streams (from the front-end cameras) forwarded from the unified management platform, then overlay the corresponding OSD tags, and then encode them. The unified management platform then forwards the video stream processed by the "decoding / encoding gateway" to any one of the multiple higher-level video platforms. Controlled by a unified management platform, it automatically outputs video streams with different compression methods to multiple upstream platforms, such as supporting mixed compression and output of 1080P, 720P, D1, etc. under different H.265 or H.264 encodings. The unified management platform's OSD control management commands provide the OSD and target video stream encoding as needed.

[0087] This invention acquires video recordings through a unified management platform. Like real-time video streams, each video recording can independently undergo five (or more) different OSD overlays, along with a second encoding. The recordings are then transmitted to the upper-level video platform via a northbound GB28181 national standard streaming media gateway. Playback is handled by the unified management platform software. The unified management platform supports video expansion capabilities, managing 1000-5000 video channels, and can transfer streams to the upper-level platform on demand (via a "decoding / encoding gateway"), with future expansion capabilities. The upper-level video platforms include public security, customs, border inspection, emergency response, maritime affairs, and port groups, while the lower-level video platform is the Hikvision 8600 platform. The unified management platform retrieves video streams from the lower-level video platforms.

[0088] The method for determining whether the target video stream exists on the currently accessed video playback platform is illustrated with an example:

[0089] The target video stream is a video stream captured by a camera within the video stream stored on the Hikvision 8600 platform at the port, for example, video data captured by camera number 2 on section A of the port. The determination is made as to whether the video data captured by camera number 2 on section A of the port has been accessed, that is, whether a video playback platform has accessed the video data captured by camera number 2 on section A of the port. The currently accessing video playback platform is the border inspection unit's video platform.

[0090] 202. If so, then further determine whether the priority of the currently accessed video playback platform corresponding to the target video stream is lower than that of the target video playback platform.

[0091] Let's take step 201 as an example:

[0092] The target video playback platform is the video platform that needs to access the "video data captured by camera No. 2 in section A of the port", such as the customs unit video platform; when it is determined through step 201 that the target video stream "video data captured by camera No. 2 in section A of the port" exists in the currently accessed video playback platform "border inspection unit video platform", it is further determined whether the priority of the currently accessed video playback platform "border inspection unit video platform" is lower than the priority of the target video playback platform "customs unit video platform";

[0093] The priorities of the border inspection unit's video platform and the customs unit's video platform are defined by preset priority rules. These rules assign priority to each higher-level video platform. For example, the public security unit's video platform is level 6, the customs unit's video platform is level 5, the border inspection unit's video platform is level 4, the emergency response unit's video platform is level 3, the maritime unit's video platform is level 2, and the port group's video platform is level 1. Therefore, in this example, the priorities of the border inspection unit's video platform and the customs unit's video platform are level 4 and level 5, respectively.

[0094] 203. If so, stop the current access of the target video stream to the video playback platform; obtain the target video stream corresponding to the target video playback platform, and decode the target video stream.

[0095] Let's take step 202 as an example:

[0096] The unified management platform determines whether the priority (level 4) of the currently accessing video playback platform "Border Inspection Unit Video Platform" is lower than the priority (level 5) of the target video playback platform "Customs Unit Video Platform". If the determination result is yes, the unified management platform stops the currently accessing video playback platform "Border Inspection Unit Video Platform" from accessing the target video stream "Video data captured by camera No. 2 in Port A section". Then, the unified management platform obtains the target video stream "Video data captured by camera No. 2 in Port A section" that the target video playback platform "Customs Unit Video Platform" needs to access, and decodes the target video stream "Video data captured by camera No. 2 in Port A section" through the unified management platform's "decoding / encoding gateway" to obtain the decoded target video stream.

[0097] Furthermore, if not, the target video playback platforms are ordered according to a preset priority rule, with at least two target video playback platforms. When the currently accessing video playback platform stops accessing the target video stream, the stop duration corresponding to the currently accessing video playback platform is monitored. If the stop duration reaches a preset duration threshold, the target video stream corresponding to the target video playback platform is obtained and decoded. This ensures that subsequent accesses by multiple target video playback platforms follow the pre-ordered access sequence.

[0098] The steps are illustrated using the example above:

[0099] The preset priority rules stipulate that the priorities of each superior unit are as follows: public security unit video platform is level 6, customs unit video platform is level 5, border inspection unit video platform is level 4, emergency unit video platform is level 3, maritime unit video platform is level 2, and port group unit video platform is level 1. For example, if there are three target video playback platforms, namely emergency unit video platform (level 3), maritime unit video platform (level 2), and port group unit video platform (level 1), then it is determined whether the priority (level 4) of the currently accessed video playback platform "border inspection unit video platform" is lower than that of the target video playback platform (there are three target video playback platforms, all with priorities lower than level 3). If the determination result is no, then the three target video playback platforms are sorted from highest to lowest priority, and this sorting is used as the access order of the target video stream. Therefore, the access order of the target video stream is: emergency unit video platform (level 3), maritime unit video platform (level 2), and port group unit video platform (level 1).

[0100] When the currently accessing video playback platform "Border Inspection Unit Video Platform" stops accessing the target video stream "Video data captured by camera No. 2 in Port Section A", the stop duration (10 seconds) corresponding to the currently accessing video playback platform is monitored; if the stop duration (10 seconds) reaches the preset duration threshold (10 seconds), the unified management platform obtains the target video stream "Video data captured by camera No. 2 in Port Section A" and decodes the target video stream through the "Decoding / Encoding Gateway"; each of the target video playback platforms sends an access command to the unified management platform in the access order (Emergency Unit Video Platform (Level 3), Maritime Unit Video Platform (Level 2), Port Group Unit Video Platform (Level 1)) to access the target video stream.

[0101] 204. Obtain the decoded target video stream.

[0102] This step combines the description of step 101 in the above method, and the same content will not be repeated here.

[0103] Obtain the access instruction for the target video stream sent by the target video playback client; based on the access instruction, obtain the target video playback platform corresponding to the target video playback client and the target video stream to be accessed corresponding to the target video playback platform; calculate the resource data value according to the target video stream to be accessed; determine whether the resource data value is greater than a preset gateway computing power threshold; if not, obtain the target video stream based on the access instruction for the target video stream, and decode the target video stream to obtain the decoded target video stream; if yes, obtain the target video stream and send it directly to the target video playback platform.

[0104] Example 1:

[0105] The target video playback client is Computer No. 1 in Department A of the port group, and the target video playback platform is the "Port Group Video Platform". When Computer No. 1 sends an access command to the unified management platform through the "Port Group Video Platform", the unified management platform obtains the target video playback platform "Port Group Video Platform" and the target video stream "video stream captured by Camera No. 2 on Port A section" based on the access command sent by the target video playback platform "Port Group Video Platform" (the access command contains the target video playback platform and the target video stream information to be accessed). "Video data"; For example: if the preset gateway computing power threshold is 100, when the resource data value of the target video stream "video data captured by camera No. 2 in section A of the port" is 110, the unified management platform obtains the target video stream and sends the original video directly to the target video playback platform without processing; if the resource data value of the target video stream "video data captured by camera No. 2 in section A of the port" is 95, the target video stream is obtained based on the access instruction for the target video stream, and the target video stream is decoded to obtain the decoded target video stream.

[0106] Example 2:

[0107] The target video playback clients are five in total: computer number 1 in Department A of the port group, computer number 1 in Department A of the public security unit, computer number 1 in Department A of the customs unit, computer number 1 in Department A of the border inspection unit, and computer number 1 in Department A of the emergency response unit. Each of these five target video clients sends an access command to the unified management platform through its respective video playback platform, accessing the target video stream "video data captured by camera number 2 on section A of the port". Assuming the preset gateway computing power threshold is 100, and the resource data value of the target video stream "video data captured by camera number 2 on section A of the port" is 30, then the pre-accessed target... If the resource data value of the video stream "video data captured by camera No. 2 in section A of the port" is 5 multiplied by 30, which equals 150, then the unified management platform obtains the target video stream and sends the original video directly to the target video playback platform without processing. If the resource data value of the target video stream "video data captured by camera No. 2 in section A of the port" is 15, then the resource data value of the target video stream "video data captured by camera No. 2 in section A of the port" that is to be accessed is 5 multiplied by 15, which equals 75. Then, based on the access instruction for the target video stream, the target video stream is obtained and decoded to obtain the decoded target video stream.

[0108] 205. Superimpose the target symbol onto the decoded target video stream to obtain a video stream with superimposed target symbol.

[0109] This step combines the description of step 102 in the above method, and the same content will not be repeated here.

[0110] Based on the target video playback platform, the target symbol corresponding to the target video playback platform is obtained through a preset mapping table; the target symbol corresponding to the target video playback platform is superimposed on the decoded target video stream to obtain the superimposed target symbol video stream.

[0111] Let's take step 203 as an example:

[0112] When the target video playback platform "Emergency Unit Video Platform" sends an access command to the unified management platform, the unified management platform obtains the superimposed symbol "Emergency Unit Name" of the target video playback platform "Emergency Unit Video Platform" through a preset mapping table based on the access command sent by the target video playback platform "Emergency Unit Video Platform". The unified management platform's "OSD Overlay Management" overlays the symbol "Emergency Unit Name" onto the decoded target video stream. Then, the "Decoding / Encoding Gateway" performs secondary encoding on the target video stream "Video Data Captured by Camera No. 2 on Port A Section" with the superimposed symbol. The unified management platform then sends the encoded target video stream with the superimposed symbol to the target video playback platform "Emergency Unit Video Platform" through the GB28181 national standard streaming media gateway.

[0113] Furthermore, the target video playback client corresponding to the target video playback platform plays the overlaid target symbol video stream according to a preset access rule, and there are at least two target video playback clients corresponding to the target video playback platform. The preset access rule refers to the order in which the target video playback clients send access commands.
