9、International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technica
10、l, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in
11、turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. N
12、OTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure
13、, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does n
14、ot suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTSITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning th
15、e evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, w
16、hich may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/.

20、ation describes the service scenarios, functional requirements and reference model for visual surveillance system interworking (VSSI), based on the requirements and architectures defined by ITU-T F.743, ITU-T H.626, ITU-T H.626.1 and ITU-T H.627. A visual surveillance (VS) service is a telecommunica
21、tion service focusing on video (and audio) application technology, which is used to remotely capture multimedia (such as audio, video, image and various alarm signals), and present them to end users in a friendly manner (including accessibility aspects), based on a broadband network with ensured qua
22、lity, security and reliability. The VSSI mechanism can achieve cross-system scheduling of multimedia (such as video, audio and image) and enables the resource and data sharing of different visual surveillance systems (VSSs). 2 References The following ITU-T Recommendations and other references conta

The platform is used to integrate the capabilities of differe
32、nt visual surveillance systems and enable the resource and data sharing of different visual surveillance systems. 4 Abbreviations and acronyms This Recommendation uses the following abbreviations and acronyms: CMU Centre Management Unit CU Customer Unit PTZ Pan/Tilt/Zoom PU Premises Unit QoE Quality

34、mmendation: The keywords “is required to“ indicate a requirement that must be strictly followed and from which no deviation is permitted if conformance to this recommendation is to be claimed. The keywords “is recommended“ indicate a requirement that is recommended, but which is not absolutely requi
35、red. Thus this requirement need not be present to claim conformance. Rec. ITU-T F.743.3 (07/2016) 3 6 Scenarios This clause describes typical service scenarios illustrating visual surveillance system interworking (VSSI) and deriving its service requirements. Each visual surveillance system (VSS) has
36、 its own centre management unit (CMU), and different VSSs have different CMUs. 6.1 Cross-system real-time surveillance Case 1: Cross-system interoperation Bus company A, traffic management department B and police department C have their own VSSs. The bus company installs its VSS in its buses and bus
37、 stations. The traffic management department installs its VSS on the main traffic roads of the city. The police department also installs its VSS on some streets of city. Those VSSs can be connected by the VSSI mechanism. Customer Li is a member of the police department. Li can directly view the real
38、-time video of the VSSs of A, B and C so that he can find and handle any emergency by synthesizing a wide range of information. Step 1: The VSSs of A, B and C are interconnected through a VSSI mechanism. The VSSs of A and B open the resource access privilege for the user from C. Step 2: Li logs into
39、 the VSS of C. There, he can view a list that displays detailed information for each camera, including the camera name and position of the VSSs of A, B and C. To track a suspected target trajectory, Li watches the multiple real-time videos from the three VSSs by clicking the corresponding cameras. S
40、tep 3: While watching a surveillance video, Li can make a screenshot of it or begin to record it at any time. Step 4: If Li is not satisfied with the positioning, he can click the direction buttons on the screen to pan/tilt/zoom (PTZ) the camera to meet his need. Step 5: If an abnormal event occurs
41、in the monitoring region, the corresponding VSS can send an alert message to Li. Then Li can switch to that real-time video to observe the developing situation. Case 2: Multiple system unified access The traffic management departments of city A, city B and city C have deployed their respective VSSs
42、in the three cities. Administrator Bob of the provincial/state traffic management department wants to view the current traffic situations in all cities. Step 1: The VSSs of A, B and C are connected to a VSSI platform, which provides a resource access privilege for the user of the platform. Step 2: B
43、ob logs into the VSSI platform via his PC. There, he can view a list that displays detailed information for each camera of the three VSSs. To view the current traffic situations in the three cities, Bob simultaneously watches the multiple real-time videos from different VSSs by clicking the correspo
44、nding cameras. Step 3: If Bob is not satisfied with the positioning, he can click the direction buttons on the screen to pan/tilt/zoom (PTZ) the camera to meet his need. 6.2 Cross-system surveillance video download and playback When a burglary happens in a community, the police officer will fetch th
45、e recorded surveillance video of the community and the nearby roads to find a clue about the suspicion. Step 1: Li logs into the VSS of the police department via his computer. Step 2: The VSS provides multiple query conditions for retrieving video recordings, e.g., camera position, video starting ti
46、me and video duration. Li searches the related video recordings made before and after the incident time in the VSSs of the traffic management department and police department, and retrieves some relevant results. Li replays these video recordings 4 Rec. ITU-T F.743.3 (07/2016) to checking for any su
47、spicious behaviour. Li can play these recordings at normal speed or fast forward/backward, pause, search a specified position, stop, etc. Step 3: To further investigate the evidence, Li downloads some key video records from the VSS of the traffic management department and send the video copies to ot
48、her case investigation departments. 6.3 Alarm across different systems Administrator Bob in system A needs to receive alarm signals when premises unit (PU) of system B is triggered by some kind of event, but the customer of system A and the PU of system B are not within the same system, this scenari
49、o can be realized with the interaction of the system interworking gateway (SIG). The simplified procedure for alarm across different systems is as follows (see clause 6.1, Case 2): Step 1: Bob connects the service control unit (SCU) in system A to require an alarm signal when the PU of system B is triggered by some predefined event. Step 2: The SCU in system A performs lookup process (with the interaction of the SIG) and finds the PU of system B. Step 3: Bob sends a request to the SCU in system A to subscribe to the alarm s
