9、nternational Telecommunication Union) is the United Nations Specialized Agency in the field of telecommuni- cations. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the ITU. The ITU-T is responsible for studying technical, operating and tariff questions and issuing R

10、ecommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these

11、topics. The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with IS0 and IEC. NOTE In this R

12、ecommendation, the expression ”Administration” is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. INTELLECTUAL PROPERTY RIGHTS The ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve

13、 the use of a claimed Intellectual Property Right. The 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 Recommendation development process. As of the date of approval of this Rec

14、ommendation, the ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent datab

The National Bodies should provide t

This disposition solves the language and the legal problems raised from different countries. 2 Normative ref

39、mmunication and coordination; means of financial support for the operation When the appropriate National Body accepts the request, a probationary authorization is given to start operation of the REGAUT. During this probationary period, the REGAUT will be required to provide the appropriate National

40、Body with registered images, based on non-disclosure agreements as deemed necessary. The National Body will determine compliance of the registered images to the standard. Following the successful demonstration of compliance, the probationary number is updated to a definitive, final number and the ac

41、tual REGAUTs operations may begin. The registration numbers will be clearly differentiated when applied to probationary REGAUTs and final REGAUTs. Once approved and operational, the REGAUT shall create a number of registers for private and/or public use, and will be required to provide information r

42、egarding the items in the register. The REGAUT, at a minimum shall provide: registration process description (maybe some particular conditions); registration content in terms of quantity and numbering; on-going test period news and recommendations to users; ITU-T Rec.

Each registrant should be able to access his own registration status and review his registered images.

44、To reduce the size of the registered files and the risk of getting it disclosed, a typical registration process only registers vignettes, which are small representations of the original images, carrying ail the tags for IPR protection and a native sample taken into the original file for authenticati

45、on purposes. 5 Submission, review, and appeal process This clause provides requirements for the submission and approval of new or updated profiles, tags, colour spaces, markers and compression types as defined previously. Additionally, this clause recommends ways for the establishment of a new REGAU

46、T (Registration Authority) whose purpose will be to register images. Ali the registration processes have a common set of requirements for the submitter as well as requirements and processes based on the category of submission (PTSMCR) and are described in detail below. 5.1 Submission process The reg

47、istration submission process conforms to the specifications described in clause 4 and is graphically shown in Figure 5-1, which shows the process flow for submission of a new item to the relevant PTSMCR Authority. This process flow is focused on access based on an Internet based submission and appro

48、val system, but could be applied to other (non-electronic) processes as provided for by the Authority. The registrant (individual or institution) shall submit a request for registration of a new item to the PTSMCR Authority, possibly via Internet access, for example. The first operation is the ident

49、ification of the registrant, which takes the steps shown on the block diagram: either the registrant is unknown to the PTSMCR Authority, or previously registered an item and is listed in the PTSMCR Authority registers. If it is the first time the registrant provided a submission to the Authority, they must complete a general identification form. In order to provide some level of security to the registration process, a password is set by the registrant and must be used every time the registrant contacts the PTSMCR Authority for an active operation (this exclude
