6、illance Summary The purpose of Recommendation ITU-T F.743 is to define a visual surveillance service based on IP networks. The visual surveillance service provides the display and storage of the video captured by multiple remote cameras over an IP network for multiple users. It also provides other f
7、unctionalities such as remote control and alarming. This Recommendation provides the service description, a brief functional model, application scenarios and requirements for the visual surveillance service. The requirements for the visual surveillance service are derived from the scenarios of diffe
8、rent applications that a visual surveillance service can support. Therefore, the service requirements meet the needs of different kinds of users and enables interoperability among visual surveillance systems of different telecom operators and units of different vendors.

ITU-T F.743 (12/2009) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and
10、 communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide bas
11、is. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resol
12、ution 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. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration
13、and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are
14、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 not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the poss
15、ibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the
16、Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest inform
17、ation and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/. ITU 2010 All rights reserved.

32、d if conformance to this Recommendation is to be claimed. The keywords “is recommended“ indicate a requirement which is recommended but which is not absolutely required. Thus this requirement need not be present to claim conformance. The keywords “can optionally“ indicate an optional requirement whi
33、ch is permissible, without implying any sense of being recommended. This term is not intended to imply that the vendors implementation must provide the option and the feature can be optionally enabled by the network operator/service provider. Rather, it means the vendor may optionally provide the fe
34、ature and still claim conformance to this Recommendation. 6 Prose description Visual surveillance can provide real-time surveilled video from one or more cameras possibly located in large, complex and spatially distributed regions; hence, users can monitor and analyze remote sites. Further, the surv
35、eilled video can be recorded for replaying. Visual surveillance systems connect users and premises units with cameras and other assistant functions by various access networks. Surveilled media flow can be delivered to any specified user terminal. Users can get surveilled video in any place whenever
36、accessible. Rec. ITU-T F.743 (12/2009) 3 The surveilled video is mainly delivered from surveilled sites or from a system platform to users in one direction; however, audio flow may be bidirectionally delivered for instant communication. Premises units can be remotely controlled for the purposes such
37、 as object detection and recognition. External alarm information can be directly introduced to the visual surveillance platform or by the premises unit. The system may also generate alarm information as a result of automated intelligent analysis. All alarm information should be processed by the syst
38、em in time with operations such as triggered recording, sending notice to users and so on. Figure 1 shows a simple visual surveillance system functional model. Figure 1 VS system model A visual surveillance service system consists of premises units (PUs), a VS platform and customer units (CUs). A PU
39、 is located at a surveilled site to collect video, audio, alarm signals and other information, which can be conveyed to the VS platform and is transmitted, delivered, stored or processed by the VS platform. VS service subscribers (or users) watch the video, control the PUs remotely, and receive alar
40、m information via CUs wherever accessible. PUs and CUs can access the VS system via a fixed or a mobile network. A VS system may interwork with other systems or units such as alarm related systems, GPS, GIS, IPTV, video conference, PSTN, SMS, 3G, e-mail, IM systems, and so on. These systems are deno
41、ted by dashed rectangles in Figure 1. The alarm related systems can collect alarm signals and execute corresponding operations. 7 Scenarios This clause describes typical service scenarios illustrating the visual surveillance service and deriving its service requirements. 7.1 Real-time surveillance 7
42、.1.1 Scenario 1 Bob has subscribed to the VS service. Alice is Bobs wife. Bob, John and Smith are good friends. VS Platform PU CU User Alarm Related Systems GPS, GIS Other Systems Surveilled Object 4 Rec. ITU-T F.743 (12/2009) Step 1: Bob logs into the VS system via his PC in his office. There is a
43、camera list on the left side of the screen, which displays detailed information for each camera that Bob can access. On the right side of the screen, an electronic map of Bobs house is displayed, which can be zoomed in or zoomed out. Each camera is marked on this map. When Bob clicks a camera, a sur
44、veillance window which can be resized appears on the screen. There are also subtitles at the bottom of the surveillance window, displaying the current time, the name of the surveilled site and other information. Step 2: While watching the surveillance video, Bob can save the current view as a still
45、picture or begin to record the video at any time. The system will prompt Bob when he runs out of storage. Step 3: Bob is not satisfied with the current position of the camera, so he clicks the direction buttons on the screen to pan/tilt/zoom (PTZ) the camera to meet his need. As Bob feels that some
46、positions are used frequently, he saves them into the profile. Each of these positions is called a preset position. When a preset position is selected, the camera is panned/tilted/zoomed to that position. In addition, when Bob feels that the video is not bright enough, he turns on the auxiliary ligh
47、t near the camera by clicking the appropriate button on the screen. Step 4: Meanwhile, Alice is accessing the same camera via her mobile phone. Alice is enabled to operate the PTZ control of this camera remotely as well as Bob. However, since only one user can pan/tilt/zoom the camera at one time, a
48、nd Bob is now operating the PTZ control, Alice can only watch the video rather than control the camera. When Bob stops controlling, Alice begins to control the camera in the manner as Bob did. Step 5: Bob, John and Smith want to share their cameras installed in their gardens, so they apply the VS sy
49、stem for a closed user group. Bob is the sponsor and organizer of this closed user group. After the group is created, Bob invites John and Smith to the group, and they accept Bobs invitation. Finally, they set their garden cameras “shared within closed user group“. Now, they can mutually visit each others garden cameras. Step 6: In order to acquaint the citizens with up-to-date traffic conditions, a number of public cameras are installed on the streets. People can visit those cameras via the VS system. One day, Bob is going to go
