Recommendation ITU-T P.912 defines subjective assessment methods for evaluating the quality of one-way video used for target recognition tasks. "Target" refers to something in the video that the viewer needs to identify (e.g., a face, object, or number). Target recognition video (TRV) is video that is used as a tool in order to accomplish a specific goal through the ability to recognize specific targets of interest in a video stream. TRV can be used in various video services such as surveillance, human identification, license plate identification, telemedicine, robot control and remote monitoring and decision making.

This amendment provides a list of definitions for terms which are used regularly but often ambiguously. The reason for this ambiguity is that these terms are used in various contexts where they actually do not belong. Therefore, it was agreed to include these definitions in Recommendation P.10/G.100.

1.1 This part of ISO/IEC 18000 defines the generic architecture concepts in which item identification may commonly be required within the logistics and supply chain and defines the parameters that need to be determined in any standardized air interface definition in the subsequent parts of ISO/IEC 18000. The subsequent parts of ISO/IEC 18000 provide the specific values for definition of the air interface parameters for a particular frequency/type of air interface from which compliance (or non-compliance) with this part of ISO/IEC 18000 can be established. This part of ISO/IEC 18000 also provides a description of example conceptual architectures in which these air interfaces are often to be utilized. 1.2 This part of ISO/IEC 18000 limits its scope to transactions and data exchanges across the air interface at reference point delta (see Figure 1). The means of generating and managing such transactions, other than a requirement to achieve the transactional performance determined within this part of ISO/IEC 18000, are outside the scope of this part of ISO/IEC 18000, as is the definition or specification of any supporting hardware, firmware, software or associated equipment. 1.3 Standardization of other reference points is outside the scope of this part of ISO/IEC 18000. (See Figure 1 .) 1.4 This part of ISO/IEC 18000 is an enabling standard which supports and promotes several RFID implementations without making conclusions about the relative technical merits of any available option for any possible application. 1.5 This part of ISO/IEC 18000 also provides reference information in respect of patents that have been declared to the developers of ISO/IEC 18000 as pertinent and provides reference addresses in respect of regulations under which ISO/IEC 18000 must operate.

External terminology schemas define data as they are presented to end users of telecommunication management applications. The syntax of these data needs to be communicated over data communication interfaces to other management applications within one operator or within other companies, or to the network or service platform. External terminology schemas define identifiers, name spaces, name bindings and other data that are efficient in use to the end users. This may lead to new object classes and relations between object classes as compared to a pure conceptual approach. Hence, conceptual definitions of the information conveyed by these interfaces are not sufficient, as data syntax requirements may lead to additions and modifications of the conceptual definitions. The set of external terminology schemas is a resource of data definitions to be shared in telecommunication management applications. External terminology schemas define data used at the human computer interfaces (HCI) and to be communicated over data communication interfaces. External terminology schemas do not define these interfaces. However, ITU-T Recommendation Z.601 Data Architecture indicates how External terminology schema definitions relate to the interface definitions. External terminology schemas define the terminology and grammar of end users at their HCI. The terminology and grammar used for communication over data communication interfaces using a particular technology are defined in an internal terminology schema. Future Recommendations may provide a mapping between these schemata, but such a mapping is not provided in this Supplement . This mapping may or may not be provided via an intermediate concept schema. External terminology schemas are common for a set of user functions, data communication interfaces, and processes supported by management applications. Hence, the Directory of External Terminology Schemas will not have separate Recommendations for each of these. In summary, the following requirements apply to this directory: [R1] External terminology schemas shall define data for end user interfaces and support but do not define data communication interfaces. [R2] The use of external terminology schemas with respect to information models, e.g., Rec. M.3100-neutral, shall be defined. (See Appendix I Business Needs) [R3] The use of external terminology schemas with respect to Rec. M.3050 shall be defined. (See Appendix I)[R4] The use of external terminology schemas within the Rec. M.3020 methodology shall be defined. (See Clause 5 Rationale)

This supplement describes a proxy-aided NAT/FW traversal mechanism as a NAT traversal solution for ITU-T H.323 multimedia systems. A proxy is a logical functional entity with one or more addresses in one or more realms. It provides translation of the IP header as well as the translation of ports and addresses in the message payloads. A proxy is logically located on the edge of different realms, while it can be physically deployed in many different places in the network (private or public).

Amendment 1 to ITU-T Recommendation E.123 applies specifically to the printing of national and international telephone numbers, electronic mail addresses and Web addresses on letterheads, business cards, bills, etc. Regard has been given to the printing of existing telephone directories. The standard notation for printing telephone numbers, e-mail addresses and Web addresses helps to reduce difficulties and errors, since this address information must be entered exactly to be effective.
