20、 F.771 (2008)/Amd.1 (10/2014) Introduction Multimedia information access triggered by tag-based identification is a class of the generic multimedia services identified in Recommendation ITU-T F.700. Following the methodology given in Recommendation ITU-T F.701, this Recommendation specifies the func
21、tional model, service description and requirements for multimedia information access triggered by tag-based identification. When a users device obtains an identifier from an identification (ID) tag wherever it is attached, the device tries to find the location of associated multimedia information au
22、tomatically. Each identifier is stored in an ID tag such as a barcode, a passive/active radio frequency identification (RFID), or a smart card, so as to be recognized automatically by various types of tag readers. This feature enables the user to refer to the multimedia content without typing its ad
23、dress on a keyboard or inputting the name of objects about which relevant information is to be retrieved. This information is stored in databases somewhere in the network and provided by several service providers. Rec. ITU-T F.771 (2008)/Amd.1 (10/2014) 1 Recommendation ITU-T F.771 Service descripti
24、on and requirements for multimedia information access triggered by tag-based identification Amendment 1 Supporting multiple air interfaces Modifications introduced by this amendment are shown in revision marks. Unchanged text is replaced by ellipsis ( ). Some parts of unchanged text (clause numbers,
25、 etc.) may be kept to indicate the correct insertion points. 3.2 Terms defined in this Recommendation This Recommendation defines the following terms. 3.2.3 ID terminal: An ID terminal is a device with a capability to capture data from ID tags and write data into ID tags, and other capabilities such
26、 as communication capability and multimedia information presentation capability. The data capture capability may include a function to obtain an identifier from ID tags even with no communication capability such as barcodes and two-dimensional barcodes. Examples of equipment that use data capture te
27、chniques are digital cameras, optical scanners, radio frequency (RF) transponders, infrared data association (IrDA), galvanic wire-line, etc. Sometimes, an ID terminal is called a user terminal. An ID terminal can optionally have multiple capture devices. An ID terminal can optionally have a capabil
28、ity to communicate with multiple RF types of ID tags. An ID terminal should have a frequency band selector in case of multiple band reader/writer. NOTE As described in clause 6.1.2.1 of ITU-T H.621 Amd.1, the ID terminal may be composed of multiple ID tag Readers/Writers. For example, a camera for 1
29、-dimentional and/or 2-dimentional barcode reading and an RFID reader/writer for RFID tag reading and writing may be equipped together in an ID terminal. But also, multiple RFID readers/writers may be equipped to support different frequency bands such as HF and UHF. Otherwise, a single RFID reader/wr
30、iter may support HF and UHF bands and such an RFID reader/writer is called a dual band RFID reader/writer, or dual band RFID reader, for short. 4 Abbreviations and acronyms This Recommendation uses the following abbreviations and acronyms: 2D Two Dimensional 3D Three Dimensional B2B Business to Busi

Figure 1 High-level functional model of the multimedia information access triggered by tag-based identification 6.2 Generic service description The service defined in this Recommendation is to enable users to access multimedia information relating to real-world entities s
34、uch as objects, places and persons. Appendix I describes eight examples of the multimedia information access service triggered by tag-based identification. This service is realized by the following three operations: Rec. ITU-T F.771 (2008)/Amd.1 (10/2014) 3 1) tTag-based identifier-reading process;
35、2) ID resolution process; and 3) iInformation presentation process. 7.5 ID terminal requirements TRM-001: ID terminal is required to be equipped with at least one reader of ID tags, such as an RFID reader, IrDA receiver, or high resolution camera for barcode and two-dimensional barcode recognition.
36、An ID terminal is recommended to be equipped with a writer of ID tags. TRM-002: ID terminal is required to be equipped with a wide area public communication interface such as a mobile communication interface or an IP network interface over a Wi-Fi connection. TRM-003: ID terminal is required to be e
37、quipped with a multimedia information input/output function such as multimedia information browsing and web input function. TRM-004: When multiple ID tag readers are provided, ID terminal is required to provide the selection function of the ID tag readers. TRM-005: ID terminal can optionally be equi
38、pped with a multiple band RFID reader which supports interrogation of ID tags that use different frequency bands. TRM-006: ID terminal is required to provide a frequency band selection function if it is equipped with a multiple band RFID reader. 4 Rec. ITU-T F.771 (2008)/Amd.1 (10/2014) Appendix I S
39、ervice description in applications (This appendix does not form an integral part of this Recommendation.) I.4 Food traceability The confidence in food wavers due to problems such as bovine spongiform encephalopathy (BSE) and pesticide residue found in vegetables. Consequently, food safety has become
40、 a global issue with a central focus of the consumer. Traceability of the food chain enables tracing and tracking of food and the information at each stage of the food chain, including production, processing, distribution and sales. When a food accident occurs, consumers can search for information a
41、nd confirm the safety of the food in their refrigerators. An identifier of the food is attached to the product using RFID or a small barcode. Food chain information is associated with the identifier so that the consumer can retrieve the food information from multimedia information delivery functions
42、 via available networks. There may be a use case of dual band communication. The food chain management is a subset of the supply chain management where UHF-type RFID tags are popularly deployed. ID tags for the food traceability may be UHF-type RFID tags. An ID terminal like a cell phone needs to be
43、 equipped with a UHF-type RFID reader to capture data from a UHF-type RFID tag attached to a food item. After a safety check of a food item, and due to security reasons, an end user may want to buy the food using his/her ID terminal as a mobile commerce terminal that deploys the HF communication tec
44、hnology. For example, NFC is an HF communication technology and an NFC-equipped ID terminal can support payment for the food. From an implementation perspective, installation of two RFID readers/writers in an ID terminal is not preferable. But a dual band RFID reader/writer that supports not only a
45、single air interface but also multiple frequency bands (e.g., HF and UHF) solves the implementation difficulty. In this scenario, the ID terminal does a safety check of a food item using UHF, and does payment via HF, resulting in a dual band communication. I.8 Sightseeing information delivery Suppos
46、e that each sightseeing spot is equipped with RFIDs, infrared tags, active RF tags, or barcodes including the identifier of the location. At the sightseeing spot, a visitor with a handheld terminal automatically reads the location identifier and receives sight-seeing video clips or speech explanatio
47、n with pictures retrieved via available networks. I.9 Visitor identification and guidance service with multimedia information In this scenario, ID terminal is a kind of smart phone which has four components of interest: a UHF ID tag reader/writer, an HF ID tag, an HF ID tag reader/writer and a human
48、 presence management application. In this scenario, a visitor is given a visitor ID tag and the visitor reads that tag by the HF ID tag reader/writer and writes that information to the HF ID tag in his/her smartphone. The visitor is guided by UHF ID tags and the presence management system to the fin
49、al destination in the building. The security building has an HF ID reader at the entrance gate and UHF ID tags are installed on the walls of corridors. The HF ID reader identifies a visitor and the UHF ID reader/writer of the smart phone reads the UHF ID tags on walls and displays the direction and route to the final destination. Rec. ITU-T F.771 (2008)/Amd.1 (10/2014) 5 Therefore, a visitor who has a smartphone as described above can enter the security building by obtaining the admission credential by using the HF
