11、EWORD The 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 studyin
12、g technical, 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
13、which, in 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
14、and IEC. NOTE 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
15、(to ensure, 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 wo
16、rds does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU 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 co
17、ncerning the 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
18、 patents, which 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/.

ITU-T H.626.1 (03/2013) 1 Recommendation ITU-T H.626.1 Architecture for mobile visual surveillance 1 Scope The visual surveillance (VS) service is a telecommunication service focusing on audio and video application techn
22、ology that is used to remotely capture multimedia (such as video, image, audio and various alarm signals) and present them to the end user in a friendly manner, based on a managed broadband network with ensured quality, security and reliability. This Recommendation focuses on the architecture of a v
23、isual surveillance system with mobile units, as well as on the service flow related to mobile units, such as a mobile customer unit (M_CU), accessing real-time video streams from a visual surveillance system. This Recommendation defines the architecture, functional requirements, model, entities and
24、reference points of the mobile visual surveillance system, based on the architecture defined in ITU-T H.626. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation. At the time of pu
25、blication, the editions indicated were valid. All Recommendations and other references are subject to revision; users of this Recommendation are therefore encouraged to investigate the possibility of applying the most recent edition of the Recommendations and other references listed below. A list of
26、 the currently valid ITU-T Recommendations is regularly published.

30、ide value-added functionality supported by one or more services. 2 Rec. ITU-T H.626.1 (03/2013) 3.1.2 customer ITU-T M.60: An entity which receives services offered by a service provider based on a contractual relationship. It may include the role of a network user. NOTE In this Recommendation, Cust
31、omer has the same meaning as End User. 3.1.3 customer unit ITU-T H.626: A device located at the customer part of a visual surveillance system and used to present multimedia information (such as audio, video, image, alarm signal, etc.) to the end user. 3.1.4 functional architecture ITU-T Y.2012: A se
32、t of functional entities and the reference points between them used to describe the structure of an NGN. These functional entities are separated by reference points, and thus they define the distribution of functions. NOTE 1 The functional entities can be used to describe a set of reference configur
33、ations. These reference configurations identify which reference points are visible at the boundaries of equipment implementations and between administrative domains. NOTE 2 The definition is not only applicable to NGN, but also to other IP packet switch-based networks. 3.1.5 functional entity ITU-T
34、Y.2012: An entity that comprises an indivisible set of specific functions. Functional entities are logical concepts, while groupings of functional entities are used to describe practical, physical implementations. 3.1.6 interface ITU-T Y.101: A shared boundary between two functional units. NOTE An i
35、nterface is defined by various characteristics pertaining to the functions, physical interconnections, signal exchanges and other characteristics as appropriate. 3.1.7 media ITU-T Y.101: Plural of medium. 3.1.8 medium ITU-T Y.101: a) Specific physical support for transmission or storage of informati
36、on; b) Type of presentation of information (i.e., video, audio, text, etc.). 3.1.9 premises unit ITU-T H.626: A device located at the remote part of a visual surveillance system and used to capture multimedia information (such as audio, video, image, alarm signal, etc.) from a surveilled object. 3.1
37、.10 reference point ITU-T Y.2012: A conceptual point at the conjunction of two non-overlapping functional entities that can be used to identify the type of information passing between these functional entities. NOTE A reference point may correspond to one or more physical interfaces between pieces o
38、f equipment. 3.1.11 role ITU-T Y.110: The role is a business activity which fits in a value chain. The role is constrained by the smallest scale of business activity which could exist independently in the industry and so a marketplace will exist for every relationship between roles. 3.1.12 service I
39、TU-T Y.101: A structure set of capabilities intended to support applications. 3.1.13 service platform ITU-T H.626: A series of devices and subsystems located at the central part of a visual surveillance system.

40、to customers. The main functions include service control function, media switching, distribution, storage, control and management functions. 3.1.14 surveillant ITU-T H.626: An individual performing surveillance. 3.1.15 surveilled object ITU-T H.626: The target (such as site, human, and related envir
41、onment) on which surveillance is performed. 3.1.16 visual surveillance ITU-T H.626: A telecommunication service focusing on video (but including audio) application technology, which is used to remotely capture multimedia (such as audio, video, image, alarm signal, etc.) and present them to the end u

43、ed in a customers mobile devices. The M_CU is used to initiate the service and provide customers with video viewing. 3.2.2 mobile service portal (MSP): A series of devices and subsystems located at the central part of a mobile visual surveillance system. The MSP is the business application platform
44、of the mobile visual surveillance system. Its main functions include a unified access entrance to the business entrance of user authentication and the display list of users monitoring permissions. The MSP can carry out user authentication, query the list of monitoring permissions, synchronize user a
45、ccount information, and assist service management through the exchange of information with the centre managing unit (CMU). 3.2.3 packet-switched streaming service (PSS): A device located at the central part of a mobile visual surveillance system. The PSS is the stream media server that processes med
46、ia stream distribution between the M_CU and the VAU. The main functions of the PSS include: responding to the service request message sent by the M_CU; receiving the real-time media stream from the VAU; and distributing the stream to multiple M_CUs. 3.2.4 video access unit (VAU): A device located at
47、 the central part of a mobile visual surveillance system. The VAU is used to implement communication between the mobile customer unit (M_CU) and the units defined in ITU-T H.626.
