4 Video processing and storage

1 Scope
This Recommendation describes architecture, functional entities, reference points and service control flow
of cloud storage in visual surveillance.

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 publication, 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 the currently valid ITU-T Recommendations is
regularly published. The reference to a document within this Recommendation does not give it, as a stand-
alone document, the status of a Recommendation.

3 Definitions

3.1 Terms defined elsewhere
This Recommendation uses the following terms defined elsewhere:

3.1.1 application [ITU-T Y.101]: A structured set of capabilities, which provide value-added functionality
supported by one or more services.
3.1.2 cloud storage [ITU-T F.743.2]: A data storage model for enabling service users to have ubiquitous,
convenient and on-demand network access to a shared pool of configurable storage resources, which can be
rapidly provisioned and released with minimal management effort or service-provider interaction. In cloud
storage systems, the physical and virtual resources can be dynamically assigned and reassigned according to
user demand.
3.1.3 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.
3.1.4 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.
3.1.5 functional architecture [ITU-T Y.2012]: A set 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 configurations. These reference
configurations identify which reference points are visible at the boundaries of equipment implementation and between
administrative domains.
NOTE 2 – The definition is not only applicable to NGNs, but also to other IP packet switch based networks.
